Description:
WEARABLE ELECTRONIC DEVICE

TECHNICAL FIELD The following disclosure generally relates to an electronic device, and more specifically to a wearable electronic device, such as a smart watch.

BACKGROUND

Compared to a traditional watch, a smart watch brings additional features such as incoming call notifications, activity tracking, pushing mails or short messages (SMS) in addition of displaying time. It can interact with a distant application and display useful information to the user through a panel such as displaying a weather forecast, a caller name photo, instructions of a navigation application, or a map. It can also run local applications related to time (e.g. clock, stopwatch, alarm), health (e.g. activity tracker, step counter, heart rate monitor) that leverage local sensors (e.g. accelerometer, gyroscope, heart rate sensor) and actuators (e.g. vibrator, display). The need of offering intuitive and convenient user inputs is a key element for these new devices to facilitate human machine interaction. For example, such devices can be controlled by buttons, voice commands, a touch panel, a digital crown (e.g. Apple watch), a rotating bezel (e.g. Samsung Gear S2), or any combination of these means. A smart watch may have a small display area and have restrictions in input indicating to perform a function. Therefore, technology of detecting input indicating to perform a function of a smart watch is required.

DETAILED DESCRIPTION OF EMBODIMENTS

Development of wearable computers is accelerating with advances in technology.

Wearable computers refer to computers that a user may naturally wear like clothes, watches, glasses, and accessories. Smartphones or tablet PCs may be easily

manipulated with fingers or a touch pen but may be inconvenient because they should be carried in a pocket or bag or be held in the hand. On the other hand, wearable computers may achieve better portability than smartphones or tablet PCs because they can be worn around the wrist or worn like glasses. Specifically, as an example of a wearable computer, a wristwatch-type mobile device, i.e., a smart watch, capable of wirelessly using various services such as a diary, messages, notifications, and stock quotations has appeared in the form of a variety of products. A smart watch is a wearable electronic device.

It is contemplated that a plurality of tactile zones/parts of the present invention can be employed to enrich user interface (Ul) design for a wearable electronic device. For embodiments of this disclosure, a wearable electronic device may be a watch, portable music player, health monitoring device, computing or gaming device, smart phone, or the like. In some embodiments, the wearable electronic device is a smart watch that can be worn around the wrist of a user.

In the following detailed description, reference is made to the accompanying drawings, which form a part of the disclosure, and in which are shown, by way of illustration, specific aspects in which the present invention may be practiced. It is understood that other aspects may be utilized and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description, therefore, is not to be taken in a limiting sense, as the scope of the present invention is defined by the appended claims.

For instance, it is understood that a disclosure in connection with a described method may also hold true for a corresponding device or system configured to perform the method and vice versa. For example, if a specific method step is described, a corresponding device may include a unit to perform the described method step or corresponding function, even if such unit is not explicitly described or illustrated in the figures, and vice versa. Further, a person skilled in the art would appreciate that the features of the various exemplary aspects described herein may be combined with each other, unless specifically noted otherwise.

Figure 1 shows an example schematic diagram of a wearable electronic device 10, e.g. a smart watch. The smart watch 10 includes an electronic visual display 101 at least partially disposed within a housing (not shown) of the smart watch and having a viewable area for presenting visual information. The display 101 may be a touchscreen. The smart watch 10 includes a processor 103 configured to operate a user interface engine 105 for allowing a user to interact with the smart watch 10. The processor 103 is disposed within the housing of the smart watch 10 and is coupled with the display 101. The engine 105 for user interface may be an engine designed for graphic user interface (GUI), which may be an object-oriented graphic engine driven by user interface classes and methods. The smart watch 10 at least includes a first tactile area/zone 109a, e.g. active "index" tactile zone, and a second tactile area/zone 109b, e.g. active "thumb" tactile zone. Each zone may have one or more touch sensitive parts 1 10a, 110b. In some embodiments of this disclosure, each touch sensitive part may be a touchpad, such as resistive sensor being able to sense the position of the user's finger, or a touch sensor related part, such as a capacitive/ piezoresitive/ pressure-sensitive part being able to sense the touch of the user's finger possibly with a pressure. Preferably, low power touch sensitive solution is implemented.

In this embodiment, the smart watch 10 includes at least two tactile areas/zones 109a, 109b. These two areas/zones are located outside the display area, i.e. not blocking viewable area of the display. The areas/zones can be reached by two fingers (preferably the index finger and the thumb finger) at substantially the same time. Each area/zone is at least capable of sensing: a sliding gesture, e.g. swipe left/right and/or swipe up/down, a simple touch, e.g. click, and optionally, pressure (e.g. z-touch). These tactile areas/zones can coexist with the classical user watch inputs, e.g. buttons and a touch panel.

The smart watch 10 may also have a microprocessor 107 that can detect a single event, e.g. touch, sliding/swipe, press, on each area/zone, and can possibly combine them to form and offer advanced gesture patterns, e.g. zoom in/out, rotate. Preferably, a low power microprocessor is used for coupling with each tactile area/zone and the processor. A persons skilled in the art would appreciate that the microprocessor 107 can be integrated within the processor 103. An example of the microprocessor 107 is a sensor hub. One example form of the sensor hub may be referred to a sub-processor as recited in patent application US20140059365A1 , which is incorporated herein by reference. A person skilled in the art would appreciate that logic of algorithms described in patent application US20140059365A1 regarding interaction among interrupt sensor, sub- processor and main processor is well suited for application in implementing interaction among sensor sensitive area, microprocessor and processor of this disclosure. Those algorithms and logic thereof are incorporated herein by reference. A person skilled in the art would appreciated that necessary change may adopted when logic of those algorithms are applied in implementing interaction among sensor sensitive area, microprocessor and processor of this disclosure.

Thanks to the tactile areas/zones which are disposed outside of viewable area of the display, the smart watch 10 allows to offer: a convenient, natural and ease of use user input, an visible screen during most of the time when user interact with the smart watch, and a large set of interaction from a simple touch (e.g. a click) to advanced gestures thanks to the combination of events. In some embodiments, the tactile areas/zones are disposed beneath the watch frame which improves waterp roof n ess of the watch. In some embodiments, the tactile areas/zones can be disposed on the watch frame, e.g. the areas/zones can be directly printed on the watch frame and hidden behind a decorative part.

Edge & Inter Lug Embodiment

Figure 2a shows an example wearable electronic device having a device body and a band. The smart watch 20 includes a touchscreen 201 , a device body/watch frame/housing 202, and a band 203.

In this embodiment, an index tactile zone 209 is disposed on the edge 205 of the watch frame. The index tactile zone may be disposed between the upper right lug/horn (not shown) of the watch and the center of the edge (preferably above a crown if any). A thumb tactile zone 207 is disposed on the lower inter horn area 204 of the watch frame, which is between the lower lugs/horns 206 of the watch. The position of these two zones offers a natural, intuitive and comfortable index and thumb placement. These two zones may be disposed on the surface of the watch frame, or beneath the watch frame.

Figure 2b shows a cut view (Α-Α') how the index tactile zone could be placed within a watch frame of the example wearable electronic device shown in Figure 2a. The tactile zones/sensor(s) 213a, 213b can be placed on the inner edge 21 1 of the watch frame 202 to minimize design impact. There can be no opening on the watch frame. Waterproofness is therefore enhanced. Several possible material for the watch frame like stainless steel, plastic, aluminum, or ceramic may be used. Several technologies can be envisaged for suitable touch sensitive sensors: force touch (i.e., force sensing) sensor based on nanoparticles (e.g. solutions provided by Peratech Holdco Limited, or NANOMADE- CONCEPT SAS), metal over cap technology (e.g. solutions provided by Microchip technology, or Texas Instrument), simple self capacitive sensor, and piezoresistive sensor (e.g. solutions provided by Uneo Technology or Piezotech). In this implementation example, the index tactile zone includes 2 distinct active areas that allows to support some basic gestures/patterns: slide down, slide up, click (i.e. simple touch) or pressure sensitive touch (i.e. force touch, force sensing). One example dimension of the index tactile zone (213a + 213b) can be: 10mm long, 4.2mm wide, and less than 1 mm thick. Material applied on the tactile zones/sensor(s) may be 1 mm thick, or 0.5mm thick with local extrusion. Figure 2c shows another view of the example wearable electronic device shown in Figure 2a. A thumb tactile zone 207 is disposed on the lower inter horn area 204 of the watch frame, which is between the lower lugs/horns 206 of the watch. Figure 2d shows a cut view (C-C) how the thumb tactile zone could be placed beneath a watch frame of the example wearable electronic device shown in Figure 2a. Right corner part of Figure 2d shows the lower inter horn area 204 of the watch frame viewed from bottom of the watch. Left cut view from watch bottom shows how the thumb tactile zone 207 can be implemented beneath the watch frame 202, e.g. inner wall of inter lug/horn area of the watch frame 202. The thumb tactile zone 207 can also include two active areas 217a, 217b that allow to support basic gestures/patterns: slide left, slide right, click (i.e. simple touch) or pressure sensitive touch (i.e. force touch, force sensing). Processor and/or microprocessor aforementioned is disposed within the inner space 215 of the device body. Aforementioned mechanism for index tactile zone can be applied for thumb tactile zone as well, though dimension may vary. One example dimension of the thumb tactile zone (217a + 217b) can be: 15mm long, 2.5mm wide, and less than 1 mm thick. Material applied on the zones/tactile sensor(s) may be 1 mm thick, or 0.5mm thick with local extrusion. Figure 2e shows examples of combining basic gestures from different tactile zones to form advanced gestures. User friendly design can be achieved when basic gestures are combined together to offer advanced and sophisticated gestures. For example, a slide left with thumb + a slide up with index can form a zoom in/ expand feature in implementation, a vectoring left/up gesture (e.g. thumb finger click & hold while index finger swipe up) can form a zoom in/expand feature in implementation. A person skilled in the art would appreciate that any possible combination can be exploited and a rich set of gestures can be offered. Figure 2e shows some possible advanced gestures based on the combination of the two tactile zones. Implementation of this embodiment may be carried out by the processor and/or microprocessor with necessary algorithm(s) involved. For example, the processor receives signals from tactile zones, and interprets the corresponding gesture(s). Alternatively, the microprocessor receives signal(s) from tactile zone(s), interprets the corresponding instruction(s) (e.g. a single basic gesture input, or a combined gesture input), and sends corresponding instruction(s) to the processor. Figure 3a shows another example wearable electronic device. This embodiment is similar to Figure 2a. The difference is that Figure 3a adds one or more index tactile zone(s) 209b to further support left-handed users. This left hand supportive embodiment is a first variant that enriches the Edge & Inter lug basic implementation aforementioned. The idea is to offer an alternative index tactile zone for left-handed person that can wear watch on their right arm. In this context, three zones are implemented within the watch frame 202: right handed index zone 209, left handed index zone 209b, and common thumb zone 207. A bezel 220 may be introduced as well.

Alternate Thumb Embodiment

Figure 3b shows another example wearable electronic device. In the same spirit of the left handed embodiment, an alternate thumb tactile zone 207b can be added. This new zone can take place in the lower part of the left edge of the watch.

Left Handed with Alternate Thumb Embodiment

Figure 3c shows another example wearable electronic device. This variant provides a right-handed index tactile zone 209, a left-handed index tactile zone 209b, a common thumb tactile zone 207, a right-handed alternative thumb tactile zone 207b, and a left- handed alternative thumb tactile zone 207c.

Full Ring Embodiment

Figure 3d shows another example wearable electronic device. This variant provides a full ring tactile zones: index tactile zones 209, 209b, 209c, 209d, and thumb tactile zones 207, 207e.

A person skilled in the art would appreciate that more tactile zones can be provided, more advanced gestures and/or gesture combinations can be provided. User friendly Ul design is also enriched regardless how a potential user would wear the smart watch.

Bezel Embodiment

Figure 4a-4b show another example wearable electronic device. Similar to the full ring approach, a variant is to implement such full ring zones in a bezel area instead of on/beneath the watch frame wall. In this embodiment, touchscreen 201 and bezel ring area are beneath glass of the front surface of the watch 40. In another embodiment, bezel ring area may be disposed out of glass area of the front surface of the watch 40. As shown in Fig. 4a, a multi-zone sensor is implemented in the bezel area including a plurality of touch sensitive part 401. A person skilled in the art would appreciate that bezel ring may be disposed surrounding the glass covering the touchscreen. In another embodiment, the full ring zone is disposed on top of the watch frame around or above the glass.

This implementation may propose the same set of gestures of the Edge & Inter Lugs approach based on a plurality of zones and possible combination thereof: for example, as shown in Fig. 4b, index tactile zones 401 a, 401 b, nominal thumb tactile zones 401 e, 401d, left-handed index tactile zones 401g, 401 h, alternate thumb tactile zones 401 e, 401f, and alternate left-handed thumb tactile zones 401 c, 401 d. Figure 4c shows a cut view of part of the example wearable electronic device of Figure 4a-4b. On the top is a glass/touch panel layer 402. Around or beneath the glass is bezel 403 including a plurality of tactile zones. A layer of nanomade sensor 407 is beneath the tactile zones of the bezel. A display/touchscreen 405 is beneath the glass. Several possible material for the bezel like stainless steel, plastic, aluminum, or ceramic may be used. Aforementioned touch sensitive sensor technologies can be envisaged for suitable tactile sensors. As an embodiment, conventional capacitive touch panel may be replaced and be outclassed by this approach: glass + display + bezel with tactile zones.

Figure 4d shows another example wearable electronic device. The left above-view figure shows a variant of Fig. 4a. In terms of implementation, beneath tactile zones 401 is a force touch multi zone sensor(s) which can be disposed within the watch frame or directly beneath the bezel (see right side-view figure). Note that in the first option, waterp roof n ess is enforced. In this figure, pointers 410 are showed. Pointers 410 could be a helpful option to concentrate the force on the sensor helping a better detection for each zone. An implementation example of the pointer methodology may be a point element mechanism as described in patent application PCT/EP2015/072757 filed on October, 1 st , 2015, which is originated from one of the inventors of this disclosure, and is hereby incorporated by reference in its entirety. Figure 4e shows possible gestures supported by the example wearable electronic device of Figures 4a-4d. A person skilled in the art would appreciate that this full ring and quasi "continuous" sensor solution opens the door of new possibilities of gestures and combinations thereof, such as clicking or sliding around the clock. This allows to offer new basic and advanced possible gestures as shown in Figure 4e. Gestures of Figure 4e are provided as examples, a person skilled in the art would appreciate more possible ones, e.g. examples provided in Figure 2e. Smart Strap/Band Embodiment

Figure 5a (left figure) shows another example wearable electronic device. This implementation leverages the strap/band of the watch. In this embodiment, the two tactile zones 501 , 503 are located on a lower and an upper strap of the watch. The upper part can be dedicated to an index finger as the index tactile zone while the lower one can be dedicated to a thumb finger as the thumb tactile zone. This embodiment may be implemented in combination with aforementioned embodiments as well, i.e. watch frame 202 with tactile zone(s), bezel 220 with tactile zone(s), inter rug/horn area 204 with tactile zone(s), and display 201 with touch panel. The tactile zones preferably uses Nanomade technology (e.g. force touch). It allows to: place the tactile zone(s) on the inner side of the strap to minimize the impact on design; use any applicable material for the strap (e.g. leather, plastic, metal); offer pressure sensing in addition to the basic set of sensing (e.g. swipe, touch) to enrich Ul design.

Figure 5a (right figure) shows an implementation of this embodiment which provides more than one active zone/sensor for each tactile zone 501 , 503, e.g. two active

zones/nanomade sensors 501 a, 501 b for the index zone 501 , and four active

zones/nanomade sensors 503a for the thumb zone 503.

A person skilled in the art would appreciate that this smart strap/band solution opens the door of new possibilities of gestures and combinations thereof. This allows to offer new basic and advanced possible gestures as shown in Figure 5b. Figure 5b shows possible gestures supported by the example wearable electronic device of Figures 5a. Gestures of Figure 5b are provided as examples, a person skilled in the art would appreciate more possible ones, e.g. examples provided in Figure 2e and Figure 4e.

Figure 5c shows an example implementation of the example wearable electronic device of Figures 5a. A simplified broken view of the strap/band 203 of the smart watch 50 is shown at the left corner. The applied material layer(s) 203-1 , 203-2 (e.g. leather, plastic, or metal) may be 1-1.7 mm thick. Beneath the applied material, the active tactile layer(s) 503-1 , 503-2 may be of a 22 mm * 15 mm dimension. Figure 6 illustrates major electrical components of a wearable electronic device 601 (e.g. the wearable electronic device illustrated in Figure 1- Figure 5c) employing the present disclosure. The wearable electronic device 601 includes one or more central processing units (CPUs) 602 (e.g. one or more application processors) which are primarily responsible for carrying out arithmetic, logic, and control operations. The CPU 602 may include a floating-point unit (FPU) and/or a co-processor (not shown). Additionally, the CPU 602 may be a general-purpose processor, a digital signal processor (DSP), or other state machine circuit.

A memory unit 604 for storage of data and program code/instructions is coupled with the CPU 602 through a system bus 605. The memory unit 604 may include a memory cache, random access memory (RAM), video RAM (VRAM), and/or read only memory (ROM). In addition, the memory unit 604 may encompass mass storage media, such as magnetic and optical memory media.

The CPU 602 also communicates with input/output (I/O) ports 606 through the system bus 605. The I/O ports 606 allow the CPU 602 to receive and transmit data from and to the outside environment. Thus, various input and output components of the electronic device 601 , such as the display screen 618, the input buttons/crown/bezel 608, and active tactile zones 620 are coupled to the I/O ports 606 for transmitting and receiving data to and from a user, respectively. The CPU 602 may access the I/O ports 606 as either memory mapped I/O space or as separately mapped I/O space. In addition, the I/O ports 606 may be configured to support interrupt-driven CPU access.

According to an embodiment of the present invention, the I/O ports 606 are also coupled to a network 612, such as the Internet wireless communications network. Preferably, communications over the network 612 is achieved over a wireless connection between the electronic device 601 and a network server (not shown). Various communication protocols may be supported by the wearable electronic device 601 , including but not limited to Hyper Text Transfer Protocol (HTTP), Post Office Protocol (POP), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), Wireless Application Protocol (WAP), 3GPP communications technologies (e.g. GSM, WCDMA, LTE, LTE-A, 5G), WiFi (the name of a popular wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections; Wi-Fi™ is a trademarked phrase that means IEEE 802.1 1x) and Bluetooth (a wireless technology standard for exchanging data over short distances, which is managed by Bluetooth Special Interest Group).

BLUETOOTH™ is a Trademark owned by Telefonaktiebolaget LM Ericsson. It should be noted that the protocols listed above are provided as examples only; it is contemplated that many other protocols known by those skilled in the art may be supported by the wearable electronic device 601. In one embodiment of the present invention, the wearable electronic device 601 is working as a Wi-Fi AP. Figures 7a-7b shows a schematic block diagram of the components of a user interface of the wearable electronic device 10 (e.g. a smart watch) according to Figure 1. Specifically, FIG. 7a shows a schematic block diagram of a wearable electronic device 702 without showing active tactile zone implementation. FIG. 7b shows a schematic block diagram of the wearable electronic device 702 with active tactile zone(s) implementation 401 shown.

Figure 8 shows another example schematic diagram of a wearable electronic device according to an embodiment. In this implementation, gesture(s) input from touch panel and active tactile zone(s) can be combined to enrich Ul design. Similar to Figure 2e, a person skilled in the art would appreciate that any combination can be exploited and a rich set of gestures can be offered, such as examples provided in Figure 4e and Figure 5b.

Advantage of embodiments of this disclosure lies at least in the following: at least two active tactile zones outside the display area that can bring sophisticated gesture patterns when combined together; each zone can be reached by a finger, e.g. an index finger, and another finger, e.g. a thumb finger, at substantially the same time to offer a multi-touch patterns that are intuitive and comfortable to use.

This provides following benefits over conventional arts. A larger set of gestures than conventional gesture inputs is supported. Further, the display is not hidden. The usability of the device and thus the user convenience is improved. The novel functionality of the claimed device has minimal impact on design and mechanics, without affecting the waterproofness of the device. Moreover, sliding both thumb finger and index finger to interact with a smart watch is user friendly. Thus, supporting sliding gesture detection of both fingers introduces a user friendly Ul design.

Figure 9 provides a table showing advantages of the active tactile zone solution, i.e. Thumb & Index Touch, provided by this disclosure over conventional arts.

In this disclosure, "active" (tactile zone) means the tactile zone remains in a power saving standby mode (similar to touchscreen standby mode, or fingerprint reader standby mode), but ready to respond quickly to any gesture input. While a particular feature or aspect of the disclosure may have been disclosed with respect to only one of several implementations or embodiments, such feature or aspect may be combined with one or more other features or aspects of the other implementations or embodiments as may be desired and advantageous for any given or particular application. Furthermore, to the extent that the terms "include", "have", "with", or other variants thereof are used in either the detailed description or the claims, such terms are intended to be inclusive in a manner similar to the term "comprise". Also, the terms "exemplary", "for example" and "e.g." are merely meant as an example, rather than the best or optimal. The terms "coupled" and "connected", along with derivatives may have been used. It should be understood that these terms may have been used to indicate that two elements cooperate or interact with each other regardless whether they are in direct physical or electrical contact, or they are not in direct contact with each other. Although specific aspects have been illustrated and described herein, it will be appreciated by those of ordinary skill in the art that a variety of alternate and/or equivalent implementations may be substituted for the specific aspects shown and described without departing from the scope of the present disclosure. This application is intended to cover any adaptations or variations of the specific aspects discussed herein.

Although the elements in the following claims are recited in a particular sequence with corresponding labeling, unless the claim recitations otherwise imply a particular sequence for implementing some or all of those elements, those elements are not necessarily intended to be limited to being implemented in that particular sequence.

Many alternatives, modifications, and variations will be apparent to those skilled in the art in light of the above teachings. Of course, those skilled in the art readily recognize that there are numerous applications of the invention beyond those described herein. While the present invention has been described with reference to one or more particular embodiments, those skilled in the art recognize that many changes may be made thereto without departing from the scope of the present invention. It is therefore to be understood that within the scope of the appended claims and their equivalents, the invention may be practiced otherwise than as specifically described herein.
