The present invention relates to a toy system for presenting a mixed reality. More specifically the present invention relates to a toy system for superimposing images e.g. video, motion pictures and the like, on the real world.

For many years, there has been an expansion in the use of mixed/augmented reality to provide a unique and enjoyable

entertainment experience. Augmented reality typically involves providing a live displayed experience of a physical, real-world environment in which the real-world elements are augmented/mixed with computer-generated sensory input. It may be thought of as an extension of virtual reality where a player immerses himself into a physical environment in which physical laws and material

properties no longer have to be maintained. In a typical augmented reality application, the real world or surrounding environment is simply enhanced in some way.

The augmentation or enhancement provided by the augmented reality system may be video or data. For example, a video of an animated character may be displayed on a monitor or headset screen as an overlay to the real world the participant or user is viewing.

Recently, in sports, graphical overlays such as first down markers in football and strike zones in baseball have been provided in a live feed of a game to augment the viewer's experience and

enjoyment of the game.

Similarly, many mobile devices equipped with global position satellite (GPS) and cameras are equipped to overlay data related to the present position of the mobile device upon the image of the environment provided by the camera. An augmented reality system or device may also provide sound as an augmentation. For example, the displayed animations or data may be accompanied by digital tracks of music, speech, or sound effects.

However, the mixed/augmented reality used the cameras of the mobile devices and can accordingly only be viewed on the relatively small displays of the mobile device. A similar problem also exist using e.g. head mounted display wherein an images is shown on a semi-transparent display placed in front of the users eyes thereby allowing the user both to see the digital images, shown on the display, as well as the real world through the transparent display.

However, in both situations the digital image that are to be

"superimposed" on the real world, will only be visual on the display screen, e.g. on the mobile device, or on the semi- transparent display of the head mounted device and the size of the image can therefore only be altered by changing the size of the displayed image. This provides a number of disadvantages as the size of the digital image cannot be adapted to that of the real world, as said image will have the same size irrespectively of the surroundings, and the augmented/mixed reality will therefore not be perceived as "real".

Thus, it is a first aspect of the present invention to provide a toy system which can superimpose a digital image on the real world without distortion, and wherein the system is arranged for

adapting the digital image to the real world.

It is a second aspect of the present invention to provide a toy system, which easily can be customized and altered in relation to a new surroundings or image to be viewed.

It is a third aspect of the present invention to provide a toy system, which is easy and simple to operate.

It is a fourth aspect of the present invention to provide a toy system, which can use a conventional device as an image source.

It is a fifth aspect of the present invention to provide a simple toy system which can be easily assembled, used, and adjusted without requiring skill or training, and which can be used for playing different kinds of interactive games.

A toy system arranged for presenting a mixed reality is disclosed. The toy system is configured to hold an image source arranged for projecting at least one image onto a concave semi-transparent reflector thereby providing a magnified representation, i.e. a virtual image, appearing in the distance beyond the semi- transparent reflector. The toy system comprises adjustment means for adjusting the distance between the concave semi-transparent reflector and the image source and/or angle between the concave semi-transparent reflector and the image source. In some embodiments, the system comprises holding means for releasably securing the image source, such as a mobile device, in the system.

In some embodiments, the magnified representation of the image behind said semi-transparent reflector is magnified at least 1.5 times the size of the image displayed by the image source,

preferably at least 8 times, and even more preferably at least 2000 times the size of the image displayed by the image source.

In some embodiments, said adjustment means comprises a connecter, to which the concave semi-transparent reflector is attached, a longitudinal track in which the position of the connecter can be adjusted by slinging it back and forth along said track, and a fastening means for fastening the connecter at different positions along the track.

In some embodiments, the adjustment means are arranged for

automatically changing the distance and/or angle between the concave semi-transparent reflector and the image source, and wherein said distance and/or angle is changed based on the

distance between the image source and/or the surface (s) the magnified representation has to superimposed on.

In some embodiments, the system is arranged such that the distance between the semi-transparent reflector and the image source cannot exceed the focal length of the concave semi-transparent reflector.

In some embodiments, the concave semi-transparent reflector is placed at an angle of between 5 and 25 degrees in relation to the base of the toy system.

In some embodiments, the size of the concave semi-transparent reflector is between about 150 x 150 mm and about 400 x 400 mm.

In some embodiments, the concave semi-transparent reflector has an inner surface facing the image source having a radius of curvature between 300 mm and 1400 mm, preferably between about 600 mm to 800 mm. In some embodiments, the inner and outer surfaces of the concave semi-transparent reflector have substantially identical radii of curvature .

In some embodiments, the reflection layer of the semi-transparent reflector is the inner side layer facing the image source (3) .

In some embodiments, the transparency of the concave semi- transparent reflector is between 30 and 50%.

In some embodiments, the toy system comprises at least one dimming means e.g. a neutral-density filter.

In some embodiments, the image source is a mobile device.

In some embodiments, the image source is a concave image source, preferably a flexible OLED display.

According to an aspect, a view-through unit comprising the toy system is disclosed, wherein said view-through unit is an

integrated unit.

In some embodiments according to the above aspect, said unit is arranged for being releasable connected to a toy, e.g. a toy shooting device.

According to an aspect a toy shooting device is disclosed, the toy shooting device comprises the toy system or the view-through unit, wherein said shooting device is a toy gun, a toy bow or a similar shooting toy.

According to aspect, a gaming system comprising the toy system, the toy shooting device or the view-through unit is disclosed, where the toy system comprises controlling means, e.g. an APP, arranged for interacting with a game placed on a gaming means, and wherein said controlling means in combination with said toy system is further arranged for allowing magnified representations

relating to said game to be presented as free floating objects. In some embodiments according to above aspect, said controlling means is arranged for allowing the gaming means to respond to actions of the toy system.

According to an aspect, an interactive device comprising the toy system or the view-through unit is disclosed, wherein the system is arranged to display an image in the form of one or more figures and/or persons, and wherein said one or more figures and/or persons is projected onto the concave-transparent reflector providing a magnified representation, i.e. a virtual image, of the one or more figures and/or persons appearing in the distance beyond the semi- transparent reflector, and wherein the device comprises means for allowing the user to communicate/interact with the device.

In some embodiments according to the above aspect, the means for allowing the user to communicate/interact with the device is an artificial intelligence program.

In some embodiments according to the above aspect, the means for allowing the user to communicate/interact with the device further comprises a speech-recognition part/programme.

In some embodiments according to the above aspect, the device further comprises a camera and wherein the means for allowing the user to interact with the device is further arranged for detecting the users movements and in response to said movements provide feedback to the user.

In some embodiments according to the above aspect, the image source is a mobile device and wherein the means for allowing the user to communicate/interact with the interactive device is arranged for being downloaded to said mobile device.

According to an aspect, a communication system comprising the toy system or the view-through unit is disclosed, wherein the image source is arranged for performing a videoconference, and wherein at least one of the persons involved in said videoconference is displayed by the image source and projected onto the concave semi- transparent reflector thereby creating a magnified representation of the person behind said semi-transparent reflector.

According to an aspect, a method of using the toy system is

disclosed, wherein an image displayed by a first image source is projected onto a concave-transparent reflector thereby creating a magnified representation of the image behind said semi-transparent reflector ( 5 ) , and wherein the degree of magnification and/or focus point is adjusted by adjusting the distance and/or angle between the concave semi-transparent reflector and the image source.

These and further aspects are achieved according to the present invention by providing an toy system arranged for presenting an augmented/mixed reality, and wherein said system comprises an image source projecting at least one image onto a concave semi- transparent reflector thereby creating for a user a perceived magnified representation, i.e. a virtual image, of the at least one image behind said semi- transparent reflector, and wherein said system comprises adjustment means for adjusting the distance and/or angle between the concave semi-transparent reflector and the first image source.

The toy system is configured to attach, hold, accommodate, fasten or secure an image source. Alternatively the toy system comprises an image source. As the toy system is configured to attach, hold, accommodate, fasten or secure an image source, the image source may not be a fixed part of the system. The image source may be releasably secured to the system, thus the image source may be attached to the system and detached from the system. The image source may be replaced with a different image source. The image source may be retro-fitted to the system. The system may comprise holding means for releasably securing the image source to the system.

The image source is arranged for projecting at least one image onto a concave semi-transparent reflector thereby providing a magnified representation, i.e. a virtual image, appearing in the distance beyond the semi-transparent reflector. Thus projecting the image onto the reflector provides for a user/viewer a

perceived magnified representation of the image behind said semi- transparent reflector.

The image source may be an electronic device comprising a display. The display is configured to display an image. This image

displayed by the display is configured to be projected onto the reflector .

The electronic device may be a mobile device, such as a smart phone, a tablet etc.

The image source may an OLED (organic light-emitting diode) display, or a LED (light-emitting diode) display and/or the like.

The image source will project light rays onto the concave semi- transparent reflector and the light rays will be reflected by the concave semi-transparent reflector. Because of the concave shape the reflector, the light rays will be reflected towards the same point. A real image is formed if the light rays fully converge in given point, whereas a virtual image may be formed if the light rays do not fully converge at a given point. A real image forms a visible projection on a screen if the given screen is placed at the point of convergence. A virtual image may not form a visible projection on a screen, but the virtual image can be seen/imaged by the human eye, a camera or other optical instruments. Thus, the image projected from the image source onto the semi-transparent reflector will provide a virtual image and the virtual image will - when viewed by a user through the concave semi-transparent

reflector - be magnified, preferably to an extend where the magnified representation, i.e. the virtual image, has a size which corresponds to the surroundings of the real world on which the image is superimposed, thereby providing the augmented/mixed reality .

This can easily be achieved using the system according to

invention as the adjustment means ensures that the distance between the concave semi-transparent reflector and the image source and/or the angle between the concave semi-transparent reflector and the image source can be adjusted e.g. in dependence of which part of the real world the digital image are to be superimposed upon.

The terms "augmented reality" and "mixed reality" is used

interchangeable in the present application and refers to the concept that the real world or surrounding environment is enhanced by combining it with digital images.

It is in this respect preferred that the magnified virtual

representation of the image, that by the user is perceived to appear at a distance behind said concave semi-transparent

reflector is magnified at least 1.5 times the size of the image displayed by the image source. It is however preferred that the magnification is a much higher, such as between 8 and 2000 times the size of the image displayed by the image source, and in some situations it will be preferred that the magnification is even higher. However, the relevant magnification degree will e.g. depend on the size of image, and the object said image represents as well as the proximity to said surroundings, and the adjustment means of the toy system will ensure that the magnification degree can be changed according to the users wises.

An image projected onto the concave semi-transparent reflector from an image source that is located between the focal point and the reflective concave surface will appear to be magnified, and will provide a "magnified representation" of said image, i.e. a

magnified virtual image, that appears to be "virtually" further away to the eye both in terms of focus and location than the image is physically. Thus, the magnified virtual image will - from a user's perspective and when viewed through the concave semi- transparent reflector - appear to be present behind the semi- transparent reflector, such as appear to be located beyond the semi-transparent reflector. Thus, the virtual image will give the user the perception that the motive/character/object from the image is positioned e.g. across the room or far away in the sky.

The apparent focus point of the magnified virtual representation will vary as a function of the focal length of the concave semi- transparent reflector, the distance of the image source from said reflector, and/or the angle between the concave semi-transparent reflector and image source. Thus since the toy system according to the invention comprises adjustment means arranged for adjusting at least one of the distance between the image source and the concave semi-transparent reflector, the angle of said reflector in relation to the base, and the angle of the image source in relation to the base, it will be possible to obtain the desired perspective and/or desired degree of magnification. In the context of the present invention the term base, means the surface on which the toy system according to the invention is placed and/or mounted upon, and can be the ground, a toy etc.

Generally, as the image source approaches the focal length of the concave semi-transparent reflector, the magnification increases and the virtual image will from a user' s perspective appear to be further behind the semi-transparent reflector both in location and focus. It is preferred that the magnified representation i.e. the virtual image, should appear in the distance (e.g. at "infinity" in the optical sense) beyond the semi-transparent reflector, as this will create a very special and effectual combination of a digital image superimposed on the real world. As an example can be mentioned, that if the digital images projected onto the concave semi-transparent reflector are flying space ships, the system according to the invention will provide the viewer with the perception that said space ships are flying over the viewers actual physical location because the viewer can see the real surroundings behind the concave semi-transparent reflector. Since said space ships preferably are perceived as flying in the skies, i.e. at "infinity" in the optical sense, it is preferred that the distance between the image source and the concave semi-transparent reflector is near or at the focal length of the reflector. However, if the digital images instead were cars, it could be advantageously that the magnified virtual representations were presented to appear closer to the user, i.e. not at infinity, and in such situation the distance between the image source and the reflector should be smaller than the focal length of the concave semi-transparent reflector .

Thus, using the toy system according to the invention provides the possibility of adjusting the magnification and position of the magnified virtual representation, thereby blending real and virtual elements into seamless composite scenes. By combining the real world with magnified virtual images e.g. from video

processing and computer vision techniques, the system offer a natural view of real scenes enriched with "real size" virtual obj ects .

The magnified virtual representation that is viewable by a user through the concave semi-transparent reflector, will have an effective magnification range that can be changed without changing the apparent field of view or resolution. The image source, or the reflector, may be moved backwards and forwards, thus giving the effect of changing the magnification of the magnified virtual representation observed by the user without changing the apparent field of view or resolution. Furthermore, in order to ensure that the nominal user is able to view the complete magnified virtual representation, the angle between the reflector and the image source may be altered, by adjusting the angle of either the reflector and/or the image source.

Thus, the possibly of adjusting the distance and/or angle between the reflector and the image source, not only has the advantage that the magnified virtual representation of the digital image may be altered but also that the user easily can achieve a comfortable viewing condition.

It is further preferred that the toy system according to the invention comprises one or more predetermined fix-points, in which the concave semi-transparent reflector and/or the image source can be locked and wherein each fix-point provides a predetermined indication of the magnification degree of the virtual

representation of the digital image and how far beyond the semi- transparent reflector the magnified virtual representation appears in the distance.

In one preferred embodiment, the image source is placed at a fixed location, and the concave semi-transparent reflector can be manually moved back and forth using the adjustment means. In such an embodiment the adjustment means may comprise a connecter, to which the concave semi-transparent reflector is attached, at least one longitudinal track in which the position of the connecter can be adjusted by slinging it back and forth along said track, and a fastening means for securing the connecter at different e.g.

predetermined positions along the track. Said fastening means can be a simple nut and/or screw, but can in principal be any means that will ensure that the connecter, and accordingly the concave semi-transparent reflector, can be either displaced or maintained at a desired position along said track.

In an alternative embodiment, the adjustment means are arranged for automatically changing the distance and/or angle between the concave semi-transparent reflector, i.e. the changing and/or adjusting of one or more of the desired parameters, e.g. the distance between the reflector and the image source, are

automatically and will preferably be based on e.g. which images is projected by the image source and/or the distance between the toy system and the surface (s) the magnified virtual representation has to be superimposed on.

Accordingly, the toy system according to the invention may comprise means for measuring the distance between the toy system, e.g. the image source, and the relevant surface onto which the digital image is to superimposed upon. Such means can e.g. be a simple laser distance measuring means known in the art. The system according to the invention may then be arranged for collecting the thereby obtained data in relation to said distance, and wherein the system in dependence of said data is arranged for adjusting the angle and/or distance between the concave semi-transparent reflector and the image source.

In a preferred embodiment the system further comprises means which allows a user to add information as to the size (degree of magnification) of the desired magnified virtual representation of the image projected onto the concave semi-transparent reflector, and wherein the image source and reflectors position can be adjusted in dependence of said desired size .

Since it is possible to individually adjust the respective position of the elements of the system (image source and concave semi-transparent reflector) , the present invention allows e.g. the user to adjust the focus position of the magnified virtual representation of the image produced by the image source, yet maintain the resolution of the image. In other words, if the user wants to move the magnified virtual representation further away, the adjustment means ensures that the distance between the concave semi-transparent reflector and the image source can be adjusted, either automatically or manually. Similar the relevant position of the magnified virtual

representation can be altered by changing the angle of one or both of the concave semi-transparent reflector and the image source, e.g. by using a hinge arrangement connected to the concave semi- transparent reflector and/or the image source, thereby providing a more comfortable focus for the user.

Because the distance that the reflected image at the semi- transparent reflector, i.e. the virtual image, appears in the distance increases as the distance between image source and the reflector approaches the focal length of the reflector, the distance from concave semi- transparent reflector to the image source may preferably not exceed the focal length of said

reflector. If this distance exceeds the focal length of the concave semi-transparent reflector, the magnified virtual

representation becomes unstable and out of focus, and it is according desirable that the system is arranged such that the distance between the concave semitransparent reflector and the image source cannot exceed the focal length of the concave semi- transparent reflector.

Accordingly it is preferred that the toy system comprises a stop means for preventing that said distance excess the focal length of the concave semi-transparent reflector. This can in a simple embodiment be obtained by ensuring that the path/track on which the image source and/or concave semi-transparent reflector can be displaced in relation to each other, only has a length which corresponds to the focal length of the reflector, however

different means for obtaining the same effect are well known in the art and are accordingly also contemplated within the scope of the present application. A reflective substantially spherical surface of radius "R" will have a focal length of R/2. For purposes of this application, the radius of the concave semi-transparent reflector will be defined as the general curvature of the inner surface of said reflector, i.e. the side of the concave semi-transparent reflector that is facing the image source.

In use the magnified virtual representation provided by the toy system according to the invention, will together with the real world create a reality (augmented reality) of a definition and a scale never seen before and will result in a much more realistic look than anything previously achieved using conventional

augmented/mixed reality technology. Such an enhanced "illusion" broadens the possibilities of use, both as the system according to the invention can be used under a wider spectrum of conditions and due to the fact that it is possible to display more challenging images, than possible using e.g. the head mounted displays know in the art. Accordingly, the system according to the invention can be used in many games and/or learning situations.

Since the system according to the invention comprises a very few components, said system provides the advantage that a "real-size" magnified virtual representation of the desired image (s) can be provided without having a physically large system, thereby

effectively reducing costs.

The inventors of the present invention has found that if the toy system according to the invention is used in e.g. a shooting device, it is preferred to use concave semi-transparent reflectors having a size in the area between 150 x 150 mm and 400 x 400 mm, with a radius of curvature between 300 mm and 1400 mm, preferably between about 600 mm and 800 mm. This has proven to provide the desired sizes of the magnified virtual representations, as well as a light system, that easily can be carried around by the user.

However, the concave semi-transparent reflector may have other suitable sizes/dimensions depending on the intended use, and can e.g. have a size of 100 mm x 200 mm. In a similar manner the radius of curvature may vary depending on the intended use, dimension, and shape.

The concave semi-transparent reflector will preferably have a plate like shape which is e.g. substantially rectangular,

substantially circular, substantially quadratic etc. The other side of the semi-transparent reflector may have a radius of curvature that differs from that of its inner side by about the thickness of the reflector. However, since it has been observed that light which passes through a semi-transparent reflector, that has inner and outer surfaces with similar radii of curvature will be minimally distorted and its magnification minimally affected, it is preferred that the inner and outer surfaces of the concave semi-transparent reflector has a

substantial similar radii of curvature.

In a preferred embodiment the concave semi-transparent reflector and image source are placed at a mutual angle such that an viewer can be placed behind the image source and look thought the concave semi-transparent reflector without the image source disruption the view. It is accordingly preferred that the concave semi-transparent reflector is placed at an angle between 5 and 25 degrees in relation to the base on which the system according to the invention is placed. In a preferred embodiment the concave semi-transparent reflector is placed at an angle between 10 and 20 degrees, most preferably about 15 degrees, in relation to said base. The image source is preferably angled in relation to the concave semi-transparent 5 reflector, such that the image displayed by said image source is projected at the right angle onto the reflector, i.e. directly into the focus point of the reflector. The angle of the image source will in this respect depend in the distance between the concave semi-transparent reflector and the image 10 source.

Within the context of the present invention, the term "semi- transparent reflector" means a partially-reflective/partially- transmissive optical surface (a "beam splitter") where the

surface's reflectivity is used to display the simulated image as a virtual image (in the optical sense) and the surface's

transmissivity is used to allow the user to view the real world directly. Thus the term not only covers glass, but also comprises reflective and semi-transparent membranes and foils made of e.g. a polymeric composite. The transparency of the concave semi- transparent reflector is preferably between 30 - 50% as this provides the optimal conditions for the perception of the augmented reality, but the choice of transparency of the semi-transparent reflector depends on the intended application of the system according to the invention. It is preferred that the reflective layer of the "semi-transparent reflector" is the inner side layer facing the image source, as it is then possible to use the system according to the invention to create images of a definition and a scale never before possible resulting in a much more realistic look than anything previously achieved .

Alternatively the semi-transparent reflector can comprise a thin protective layer covering the reflective layer, as this will provide a larger resistance to the reflector. Said protective layer is preferably less than 400 nm, more preferably less than 200 μιη, and even more preferably less than 50 μη.

The image source can in principal be any kind of image source capable of projecting an image onto the concave semi-transparent reflector. It is however preferred that the image source is a mobile device, e.g. a mobile phone. In such situations the toy system according to the invention comprises holding means for effectively and releasably securing the mobile device in the system. Such holding means can e.g. be a pocket, arranged for sliding the mobile device into, a clip which grips the mobile device, or the like. Using a retail mobile device as the image source, will provide an inexpensive toy system, but also ensure that the maintenance of the system is almost completely

eliminated. Appropriate digital images can e.g. be downloaded to the mobile device in a conventional way, e.g. using a related APP with relevant images, videos, games or the like.

In some situations the magnified virtual representation of an object will have a tendency of being perceived as "bend" when viewed through the concave semi-transparent reflector, especially when said image is originating from a "flat" image source as a conventional mobile device. This is basically due to the fact that the distance from the "flat" image source to the concave semi- transparent reflector is not uniform over the entire projected image .

It may in this respect be preferred to use a concave image source, such as a flexible OLED display, providing the possibility of both magnifying a displayed image and at the same time change focus positions, and accordingly the light coming from the display, thereby ensuring that the image will not be perceived as a "bend" magnified virtual representation. In order to ensure that the magnified virtual representation can be viewed properly, it is important that the ambient light will not disrupt the magnified virtual representations of the images. It is accordingly preferred that the toy system comprises at least one dimming means arranged for controlling the amount of light allowed to pass though the concave semi-transparent reflector. Said dimming means can in a preferred embodiment be a neutral-density filter, (ND filter) , i.e. a filter that reduces or modifies the intensity of all wavelengths, or colours. It is accordingly preferred that the dimming means is placed on the back side of the concave semi- transparent reflector, i.e. not on the side of the reflector facing the image source.

Another preferred dimming means comprises a polarizing filter (s) arranged for being rotated to a rotational angle that control the intensity of the ambient light coming though the concave semi- transparent reflector. One example of such a system is the

RoscoVIEW™ system obtainable from Rosco Laboratories, and in which a wide width polarizing filter is installed on the concave semi-transparent reflector and a matching "camera" polarizing filter is placed between the image source and the concave semi- transparent reflector. This ensures that the light emitted though the semi-transparent reflector easily can be controlled by rotating the camera filter, since the camera filter changes the degree of cross polarization on the reflector where the polarizing filter is installed. This results in 100% control of exterior brightness as seen through the concave semi-transparent reflector. The camera filter can either be arranged to be rotated manually, or it can be arranged to be rotated automatically e.g. based on data from sensors that measures the intensity of the incoming light.

In order to comply with different weather conditions, the toy system according to the invention, may comprise a number of different dimming means, ensuring that the incoming light can be adjusted in depending on the ambient sunlight, allowing the viewer to clearly perceive the magnified virtual representation

independently on the amount of light in the surroundings.

In one embodiment according to the invention, the toy system comprises a mirror, and in a position of use the system is arranged such that the image source is placed below the concave semi- transparent reflector and the mirror is placed in front of said reflector, and wherein the mirror, the at least one image source and the concave semi-transparent reflector is arranged and

positioned such that the image from the image source will be reflected in the mirror and then projected onto the concave semi- transparent reflector, thereby creating a magnified virtual representation of the at least one image that to the user is perceived to be located behind said semi-transparent reflector. The advantage of such a system is that the image displayed by the image source will not be reversed/mirrored when viewed though the concave semi-transparent reflector, an apparent benefit if the image e.g. comprises text.

A further advantage is that the distance between the mirror and the concave semi-transparent reflector can be reduced, compared to the distance of an image source placed in front of the reflector. The adjustment means will still be arranged for adjusting the distance between the concave semi-transparent reflector and the first image source and/or for adjusting the angle between the concave semi- transparent reflector and the first image source, e.g. in order to ensure that the image from the image source is reflected at the right angle in the mirror in order to create the magnified virtual representation that is perceived by the user to appear behind the reflector .

The images projected from the image source may be still or moving images, however in a preferred embodiment the images are digital images e.g. moving pictures which presents free floating video elements, which is combined with the background in order to provide the mixed/augmented reality. The magnified virtual representation of digital images can e.g. be a space ship which needs to be shot using a shooting device that incorporates the toy system according to the invention.

It is preferred that the images projected from the monitors are isolated by their outline, whereby the quasi-3D perception of said images will be further enhanced. This technology is well known in the art, but as an example can be mentioned that the images can be isolated using a cut-out technology or be recorded against a single-coloured background. In postproduction, the background can be removed, for instance by computer processing, and be replaced with black. On the monitor device, the background will be black and only the image can be seen, thereby significantly adding to the sense that the image is physical connected with the real

surroundings, since no interference is displayed. In one preferred embodiment the toy system according to the invention is mounted on a shooting device, e.g. a toy gun, a toy bow or similar device, allowing the user to shoot magnified virtual representations of e.g. space ships, monsters, or the like. The toy system can of course also be an integrated part of such a shooting device .

It is accordingly preferred that said toy system is arranged in a view-through unit, and wherein said unit is an integrated unit arranged for being releasable connected to a toy shooting device, thereby ensuring that the unit easily van be attached to or removed from said device. This will allow a user to exchange the toy system according to the invention between different shooting devices, thereby providing a less expensive system than if the toy system according to the invention were integrated in each shooting device. In this respect the view-through unit may comprise

conventional releasable attachment means, e.g. magnetic or click- on mechanisms. Such releasable attachment means are well known in the art and will not be discussed in further details in this application .

In a preferred embodiment, the toy system is further arranged for being connected to and for interacting with a gaming means, e.g. a video game console, a personal computer or the like, thereby providing a gaming system. Such a gaming system can be utilised for playing very realistic interactive games, preferably using the conventional gaming means. In order to enable the gaming system to function as desirable, the toy system preferably comprises

computing means for obtaining, processing and sending relevant data between the toy system and the gaming means in order to ensure that the gaming means responds in relation to the actions by the toy system, e.g. if the trigger on the toy shooting device is activated and in dependence on which direction the said

shooting device points.

Such computing means are already known in the art and may e.g. be different sensory devices arranged for determine the position and orientation of the toy system, e.g. a gyroscope and an

accelerometer . Such sensory devices is already part of most conventional mobile devices, e.g. mobile phones, thus when the image source is such a mobile device, the different elements will automatically be part of the toy system according to the

invention. The means for ensuring that the respective sensory devices both can interact with and be synchronised with the gaming means, can in a preferred embodiment be a controlling means e.g. an APP that can be downloaded to the mobile device, which has been arranged for this purpose. The mobile device can be connected to the toy gun using conventional means, e.g. blue tooth, or USB. As one example, the trigger of the toy gun is connected to the USB of the mobile device, whereby said trigger will function as a switch.

The magnified virtual representation can in one embodiment of the gaming system according to the invention, be viewed on the

conventional display, e.g. an LCD-display. In such situations the toy system according to the invention may interact with

conventional gaming systems, e.g. gaming consoles such as a

Playstation®, Xbox® and/or Wii®. Thus, the games normally played on such consoles may also be played using the toy system according to the invention. In such situation the toy system may, e.g. by using appropriate application means, provide an overlay to the existing game, such that the gaming experience is provided both in a conventional manner, e.g. on the LCD-display, as well as providing magnified virtual representation that through the concave semi- transparent reflector will be perceived as coming out of the LCD display, and appear as real elements in the real world.

Such a gaming system will ensure that e.g. first person shooter games are perceived as very realistic. Accordingly, the gaming system according to the invention is not only relevant for playing games, but can also be utilised in the army, since soldiers can be trained for battle in a very realistic scenario. In a preferred embodiment the computing means of e.g. a mobile phone, are arranged such that said means not only are arranged for interacting with and be synchronised with the gaming means, but also arranged for providing the relevant data/information that provides the extra game additions.

The means for ensuring that the respective computing means both can interact with and be synchronised with the gaming means, can be a controlling means e.g. an APP that can be downloaded to the mobile device. Said controlling means may in a preferred embodiment also comprise the data/information that provides the extra game

additions. Thus, when the APP is downloaded to the mobile device, and said mobile device is used as the image source in the toy system according to the invention, the mobile device will

comprises all relevant data and means for not only interacting with and be synchronised with the game, but also that magnified virtual representations of certain elements of the game will be perceived by the user as coming out of the LCD-display, thereby providing an extra dimension to said game(s) . The user may in a preferred embodiment be able to interact, e.g. shoot down, both elements e.g. UFO ' s that are perceived a free-floating objects outside the LCD display and elements e.g. UFOs displayed only on the LCD- display .

In another preferred embodiment according to the invention, the toy system is arranged as an interactive device, and wherein the device is arranged to display an image in the form of one or more figures and/or persons. Said one or more figures and/or persons is then projected onto the concave-transparent reflector thereby creating a magnified virtual representation of the one or more figures and/or persons, which to a user is perceived to be located behind said semi-transparent reflector, and wherein the interactive device comprises means for allowing the user to

communicate/interact with the device. In this way the interactive device may be an entertainment device and/or a learning device. The means for allowing the user to interact with the device is preferably an artificial intelligence program arranged to adapt to the user's individual preferences, and which during continuing use will evolve in order to meet a user' s changing demands or

requirements. In a preferred embodiment the artificial intelligence program is either incorporated in the interactive device according to the invention, or said program is part of an APP, that can be downloaded to the device. If the image source is a mobile device, such an APP can easily be installed on the mobile device in a conventional manner.

As an example of a preferred use can be mentioned, that if the user is interested in learning a language, the artificial

intelligence program can via the one or more figures/persons perceived by the user, start by providing beginners lessons to the user, and in response to the users developments gradually change the level of difficulty to a more advanced level. It is in this respect preferred that the artificial intelligence program

comprises a speech-recognition part/programme, in order to ensure that the program can understand the user and provide the user with an individual feedback. Alternatively, the user may simply communicate with the virtual figures/persons, e.g. in such a manner that said one or more figures/persons in response to the users demands can respond to questions, sing a song, tell a story, dance etc.

In situations where the interactive device further comprises a camera, the means for allowing the user to interact with the device may be further arranged for detecting the users movements and in response to said movement provide feedback to the user, thereby learning the user to make certain moves, e.g. dance moves, yoga position, etc., and correct the user if the move(s) are not correct .

If the image source is a mobile phone or similar mobile device, said image source will normally comprise a camera which can be used in the device according to the present invention.

The figure (s) /person (s) can be one or more full figures or be part of the figure, e.g. the head, and it is preferred that the system is arranged such that the figure (s) /person (s) easily be change depending on the users preferences. For instance a child learning mathematic might be more responsive if he/she leans the language from an idol, e.g. a cartoon figure, a football player etc., and dance moves may be more interesting if several dancers are

displayed .

In a further embodiment the toy system is arranged as a

communication device, comprising an image source arranged for performing a videoconference, and wherein at least one of the persons involved in said videoconference is displayed by the image source and projected onto the concave semi-transparent reflector thereby creating a magnified virtual representation of the person behind said semi-transparent reflector, thereby creating the illusion that the person (s) part of said conference is present in the same room as the user.

The present invention also relates to a method of using the toy system according to the invention. In said method an image from an image source is projected onto a concave semi-transparent

reflector thereby creating a magnified virtual representation of the image, which to a user is perceived to appear behind said semi-transparent reflector. As already discussed earlier it will be possible to adjust the degree of magnification of said image and/or the viewers focus point by adjusting the distance and/or angle between the concave semi-transparent reflector and the image source, thereby ensuring that the viewer is always provided with the best visual experience.

The present invention thus provides for an toy system, that provides a large magnified virtual image without a large image source. The relative cost of the system is therefore relatively low. By including at least one adjustment means, the toy system according to the invention is not only capable of providing different degrees of magnification, but also that an augmented reality is provided having magnified virtual representation of a desired degree, e.g. a real-size, that is not possible with conventional augmented reality toys.

The invention will be explained in greater detail below,

describing only exemplary embodiments of the display with

reference to the drawing, in which Fig. 1 is a schematic view of a toy gun comprising the toy system according to the invention in a first position, and Fig. 2 shows the toy gun of fig. 1 seen from above, Fig. 3 shows the toy gun of fig. 1, wherein the toy system according to the invention is in a second position, and Fig 4 shows a preferred use of the toy gun in fig. 1 communicating with a conventional gaming means.

The invention will be described below with the assumption that the toy system is mounted on a toy gun. However, this assumption is not to be construed as limiting, and the toy system could just as easily be an interactive device or a communication device.

Fig. 1, 2 and 3 shows a schematic representation of a toy system 1 in accordance with the principles of the present invention mounted on a shooting device 2, which in the embodiment shown is a toy gun. The toy system 1 comprises an image source 3

projecting at least one image 4 onto at least one concave semi- transparent reflector 5 thereby creating a magnified virtual representation 6 of the image that is perceived by a user to be located at a distance behind said semi-transparent reflector.

In the embodiment shown the image source 3 is a conventional mobile phone that can be secured to the shooting device by sliding said phone into a rigid pocket 7. Said rigid pocket has an opening 8, allowing the display 9 of said phone 3 to project an image 4 onto the concave semi-transparent reflector 5. The image 4 projected from the image source 3 onto the semi- transparent reflector will - when viewed by a user through the concave semi-transparent reflector 5 - appear to be a magnified version of the image 4. This ensures that the virtual images can be perceived as images of real-size depending on the relevant

environments, i.e. the system allows the magnified virtual

representations 6 to have a size, that will ensure that the magnified virtual representation more naturally blends into the surroundings than hitherto known, thereby providing a more

realistic augmented reality experience for the user.

A dimming means 10, in the form of a neutral-density filter, is placed in front of the concave semi-transparent reflector 5, seen in the position of use, such that the amount of light that is allowed to pass though the concave semi-transparent reflector 5 are reduced or modified. The filter 10 is preferably placed only a short distance in front of the concave semi-transparent reflector 5, in order to prevent ambient sunlight from passing though said reflector. Accordingly, said filter 10 also have a larger

dimension than the reflector 5, as this also will prevent

undesired light from entering the concave semi-transparent

reflector 5. It is thereby ensured that the magnified virtual representation 6 can be viewed properly irrespectively of the amount of ambient sunlight, since the filter 10 will ensure, that ambient light will not disrupt the magnified virtual

representations 6 of the images 4.

The neutral-density filter 10 is placed in a holder 11 having a clip-on mechanism 12, such that the filter 10 easily can be exchanged in dependence on the amount of ambient sunlight. As the concave semi-transparent reflector 5 can be subjected to damage during use, e.g. scratches can are made in the surface, the concave semi-transparent reflector 5 is also placed in a holder 13 with a clip-on mechanism 14, allowing for an easy exchange. The exchange-mechanism can also be used, if the sizes of the concave semi-transparent reflector and/or filter are to be adjusted.

In order to ensure that the magnified virtual representation 6, that is viewable by a user through the concave semi-transparent reflector 5, will have the desired size (magnification degree) , the concave semi-transparent reflector 5 is via its holder 13,

connected to an adjustment means 15, that allows the distance X between the image source 3 and the concave semi-transparent reflector 5 to be changed. In the embodiment shown this is obtained by moving the concave semi-transparent reflector 5 backwards or forwards, represented by arrow A. The virtual magnification 6 of the projected image 4 can then be altered without changing the apparent field of view or resolution of the image 4. A similar effect is of course possible by moving the image source 3 backwards or forwards, however in the shown embodiment, the placement of the image source on the shooting device 2 is fixed, as this will ensure that there is fewer parameters which can be altered by the user, making the toy system 1 easier to be used for small children.

The adjustment means 15 comprises a connecter 16, to which the concave semi-transparent reflector 5 is attached, and a track 17 (best seen in fig. 2) in which the position of the connecter 16 can be adjusted by slinging it back and forth along said track. The adjustment means further comprises a fastening means 18 for

securing the connecter at different e.g. predetermined positions along the track 17. Said fastening means can be a simple nut and/or screw, but can in principal be any means that will ensure that the connecter 16, and accordingly the concave semi-transparent

reflector 5, can be either displaced or maintained at a desired position .

In the embodiment shown both the concave semi-transparent reflector 5 and the filter 10 are attached to the connecter 16 via the holders 11 and 13, whereby the position of the filter 10 in

relation to the concave semi-transparent reflector is fixed, thereby ensuring that of ambient sunlight effectively is blocked out independently on the position of the concave semi-transparent reflector, since concave semi-transparent reflector 5 and filter 10 will maintain their mutual distance.

In fig. 1 and 2 the concave semi-transparent reflector 5 is placed in a first position wherein the distance X between said reflector 5 and the image source 3, is near or at the focal length of the reflector 5. At said distance, i.e. the focal length of the reflector 5, the magnification of the image from the image source 3 increases and the magnified virtual representation appears to be further behind the semi-transparent reflector 5 both in location and focus. Thus, at the position shown in fig. 1 and 2 the magnified virtual representation (virtual image) appears in the distance (e.g. at "infinity" in the optical sense) beyond the concave semi-transparent reflector 5, thereby creating a very special and effectual combination when superimposed on the real world.

However, when concave semi-transparent reflector 5 has been moved along the track 17 towards he image source, as e.g. shown in fig. 3, the distance X' between the image source 3 and reflector 5 will be smaller than the focal length of the reflector 5 and the

magnified virtual representation will be smaller and appear to be closer to the user, than using the distance X in fig. 1 and 2. This situation can provide a very realistic reality when the images are desired to be perceived at a closer range, e.g. on surroundings closer to the user.

As is evident from the figures, the concave semi-transparent reflector 5 and the image source 3 are placed at a mutual angle such that a user can stand behind the image source 3 and look thought the concave semi-transparent reflector without the image source disrupting the view. It is accordingly preferred that the concave semi-transparent reflector 5 is placed at an angle a

between 5 and 25 degrees in relation to the base B of the gun 2, i.e. the surface 2' of the gun on which the concave semi- transparent reflector 5 is placed. The image source 3 is preferably also angled in relation to the concave semi-transparent reflector 5, such that the image displayed by said image source is projected at the right angle onto the reflector, i.e. directly into the focus point of the reflector. The angle will in this respect depend in the distance X between the concave semi-transparent reflector 5 and the image source 3.

In order to ensure that the nominal user eye position is able to view the complete magnified virtual representation 6, e.g. if the distance between the reflector 5 and image source 3 is alerted, it might be desirable to change the mutual angle between the reflector and the image source, e.g. by adjusting the angle of the image source 3 represented by arrow 19. The rigid pocket 7 is accordingly placed on a hinge 20 such that said angle can be changed. Said hinge can preferably be locked in a desired angular position and be changed when the distance X is between the concave semi- transparent reflector and image source is altered. In a similar manner the connector 16 can comprise a hinge (not shown) for adjusting the angle of the concave semi-transparent reflector 5 and filter 10. Thus, different parameters of the concave semi-transparent reflector and the image source can be altered and/or adjusting, both ensuring that the desired degree of magnification can be provided, and that the user easily can obtain a comfortable viewing condition.

Fig. 4 shows a gaming system 21 according to the invention using the toy system 1 according to the invention. Said gaming system is arranged for being connected to and for interacting with a gaming means 22, e.g. a video game console, which in the shown embodiment may be a Playstation®, an Xbox®, a Wii® or a similar device arranged for playing games, and wherein said game is displayed on a conventional display 23, e.g. a LCD.

The user have downloaded an appropriate APP to a mobile phone that are to be used as the image source 3. Said APP is preferably arranged such that it is ensured that the respective computing means of the mobile phone both can interact with and be

synchronised with the gaming means, and comprises relevant

controlling means with the data/information that provides the extra game additions. Thus, when the APP is downloaded to the mobile device, and said mobile device is used as the image source in the toy system according to the invention, the mobile device will comprises all relevant data and means for not only interacting with and be synchronised with the gaming means 22, but also that magnified virtual representations of certain elements of the game will be perceived by the user as coming out of the LCD 23, thereby providing an extra dimension to said game(s) .

Thus, using the toy system in combination with e.g. a mobile phone as the image source 2, a relevant APP and the gaming means 22, will provide an overlay to the existing game, such that the gaming experience is displayed both in a conventional manner, e.g. by displaying part of the game 24 on the LCD-display 23, as well as providing one or more magnified virtual representation 25 that will be perceived as coming out of the LCD display 23 when viewed through the concave semi-transparent reflector 5, and appear as "real elements" in the real world. Such a magnified virtual representation 25 is in fig. 4 illustrated extending outside both the concave semi-transparent reflector 5 and the filter 10, as the viewer will pensive these as being behind both the reflector 5, and the filter 10, even though they are viewed through the concave semi-transparent reflector 5. Additionally the APP, mobile device and computing means are - either alone or in combination - arranged for ensuring that the gaming means responds to actions of the toy system 1, e.g. if the trigger on the toy gun 2 is activated, said APP, mobile device and computing means will calculating if the target is hit, and respond accordingly, e.g. by showing that the element that was shoot explodes. The user may thus be able to interact, e.g. shoot down, elements e.g. the space capsule 26 shown through the concave semi- transparent reflector 5, and which are perceived a free-floating objects outside the LCD display 23 as well as elements e.g. the space ship 27 displayed only on the LCD-display 23.

The images projected from the image source may be still or moving images, however in a preferred embodiment the images are digital images e.g. moving pictures which presents free floating video elements, which is combined with the background in order to provide the mixed/augmented reality. The virtual representations of the digital images can e.g. be a space ship which needs to be shot using a shooting device that

incorporates the toy system according to the invention.

In one implementation, for example, the reflector has a diameter of 300 mm and a radius of curvature in the order of about 600 mm for the inner surface. This results in a focal length of about 300 mm for the reflector. When the distance X between the reflector 5 and the image source 3 being about 1/2 the radius of curvature of reflector, i.e. 300 mm, the viewer is provided with a view through the reflector 5 in combination with a magnified virtual reflected image 6 that appears to be at an infinite distance beyond the concave semi-transparent reflector.

In the embodiment show in the figures, the distance between concave semi-transparent reflector 5 and the image source 3, can be adjusted to be between 150 mm and 300 mm, e.g. by providing a track having a length of 150 mm, on which the concave semi- transparent reflector can be displaced. This will also effectively ensure that the distance between the concave semi-transparent reflector and the image source does not exceed the focal length, thereby providing an unstable magnified virtual representation.

In the embodiment shown, the concave semi-transparent reflector is preferably curved to be a "substantially spherical" surface, meaning that its surface is not perfectly spherical but is

sufficiently close to being spherical so as to behave similarly to a perfectly spherical surface within the context of these embodiments .

It has however been discovered, that providing a slightly

aspherical but still substantially spherical inner surface of reflector can help to correct for keystone and barrel distortion in the image as reflected to it from image source 3.

Thus, the present invention provides a simple but yet effect-full toy system, capable of providing more real-size images without prior training even by persons without any technical skills. In this respect the invention provides a low cost, compact and customisable system, which easily can be implemented into existing gaming systems.

Modifications and combinations of the above principles and designs are foreseen within the scope of the present invention.
