Field of the Invention This invention relates to a user interface for a product ordering system. In particular, the product ordering system user interface is arranged to be operable by a user from within a vehicle.

In particular, the invention is an extension of or part of an automated product ordering and delivery system, in which orders for goods - preferably packaged goods - are received from a user via the user interface and are automatically processed to subsequently dispense the ordered products. The invention finds particular application in a 'drive-through' scenario in which orders are placed at an ordering bay, or at a roadside via a user interface accessible via a window of a vehicle.

Background to the Invention

Drive-though ordering and delivery is commonly encountered at fast food outlets. However, as is known in the art, orders are processed manually. In particular, a driver of a vehicle is prompted to stop alongside an ordering station, lower the window of the vehicle and read out their order to an employee of the fast food outlet. The order is made either directly to the member of staff, or is transmitted via a microphone at the ordering station. When transmitted via a microphone, the ability for the member of staff to understand what the driver is saying can be seriously affected by factors such as background noise, even if the microphone being used is of high quality.

The driver is then prompted to move the vehicle along to the window of a delivery station to finalise the transaction of paying for and collecting the order. This can be awkward or impossible depending on the relative positioning of the vehicle and delivery station windows, and necessitates the driver and the serving employee to reach out to one another. Nonetheless, this makes it relatively easy for goods and payment to be exchanged between the employee and the driver, especially when compared to a situation where there may be no serving employee. Accordingly, there is a prejudice in the art that in the ordering and delivery of goods such as fast food products in a drive- through scenario, employees must be provided to interface with the driver. This model has remained unchanged for many decades, and so there is a resistance to automate this process. By way of comparison, automated services provided in the context of a drive-through scenario are known for systems such as drive-through automatic bank teller (ATM) systems. However, the problem remains that the vehicle window must be positioned close enough to the ATM to enable the driver to operate its controls. Furthermore, even if the vehicle is manoeuvred so that it is close enough to the ATM, different vehicles have different heights, and so a driver of a low vehicle will have to reach up, whereas a driver of a high vehicle will have to stretch downwards. This results in drivers being discouraged from using such 'drive up' ATM systems.

This issue is considered by Kenyon in US Patent Number 4,735,289, the contents of which are hereby incorporated by reference. Kenyon describes a solution to this problem by providing the ATM machine with a detector that determines the position of an open window of a vehicle, and a carriage for moving the controls of the ATM horizontally and vertically so that they are positioned adjacent the open window of the vehicle so that the ATM can be more easily operated by a person in that vehicle.

Furthermore, Kenyon also describes the extension of the concept to a system capable of dispensing items instead of money. However, Kenyon has a number of drawbacks associated with the ease with which a driver can operate the user-interface.

Firstly, the user has little control over the operation of the carriage component.

Accordingly, once the carriage is moved forward into position adjacent the vehicle window, the user cannot open the vehicle door until the transaction with the ATM has finished. This may be inconsequential in the ATM scenario envisaged by Kenyon as the user is likely to have no reason to open the door of the vehicle.

Secondly, the device of Kenyon is limited in its capabilities, at least in part, by the lack of space on the user interface. As such, the number of functions that are provided by the user interface is restricted to only that which is required for typical ATM

transactions.

Thirdly, the device of Kenyon is exposed such that the security of the transactions may easily be compromised. For example, if a user is entering a security code (e.g. a PIN number), this may be easily visible to third parties within the vicinity.

Fourthly, the device of Kenyon may be physically uncomfortable or inconvenient for a driver to use. The controls are presented through the open side window of the vehicle. Accordingly, the driver needs to swivel his or her upper body sideways from a normally forward-facing position. This can be uncomfortable to do, especially for long periods. Also, merely opening the window of the vehicle to operate the device of Kenyon may cause additional discomforts if there are adverse weather conditions. Obviously, heating and air-conditioning systems become less effective when the window of the vehicle is down, and if it is raining, then the driver will get wet. However, bright sunlight can also cause problems, in that displays such as backlit electronic displays become less visible. Fifthly, Kenyon focuses primarily on the provision of ATM services and so does not provide a device capable of receiving product orders in an efficient and user-friendly manner, and further ineffectively addresses the issue of the delivery of those ordered products. In particular, Kenyon describes that the carriage system has to move back- and-forth many times between a retracted position and a position adjacent the open window of the vehicle so as to, in order, extended to approach the vehicle to receive a product order, retract to transfer the ordered product into a chamber, extend again to deliver the product to the user and then retract again to its rest position to allow the vehicle to pull away. Many more back-and-forth iterations may be necessary depending on the size of the product order relative to the product chamber. This is highly inconvenient and time consuming.

It is against this background that the present invention has been devised. Summary of the Invention

From a first aspect, the invention resides an electromechanical user interface for a product ordering system, the user interface comprising:

one or more user-interactable components for use by a user from an open window of a stationary vehicle;

a support structure for supporting the one or more user-interactable components;

drive means for driving the support structure relative to the vehicle; and a detector for determining the position of the open window of the vehicle, said determination being used to control the drive means so as to adjust the position of the support structure relative to the vehicle between:

a first position at which the support structure is spaced from the vehicle; and a second position at which the support structure is adjacent to the open window of the vehicle, the second position thereby facilitating user interaction with the one or more user-interactable components. Preferably, the user interface comprises a mantle defining, at least in part, a mouth through which the user-interactable components are manually accessible by the user.

Preferably, said one or more user-interactable components comprise one or more data communication modules arranged to communicate information between the user and the user interface. Preferably the information communicated relates to products and/or product orders.

The mantle advantageously improves the interaction between the user and the one or more user-interactable components. For example, if a user-interactable component is a data communication module in the form of a backlit electronic display screen, then the mouth in which it resides improves the visibility of the screen by shielding it from glare. Alternatively, if the data communication module employs audio communication, then the sound transmittal between the data communication module and the user is improved, as the mantle is able to direct the sound and provide a shield against external noise.

Furthermore, the mantle can improve the comfort of the user interacting with the user interface. In particular, the mantle can form a hood over the open window of the vehicle. This can cover the user and the interior of the vehicle from the external environment. For example, the hood can protect the user from the rain. In addition, the mantle can minimise heat transfer between the interior of the vehicle and the external environment, maintaining the effect of a vehicle's heating or air-conditioning systems. A further advantage of the mantle is that it protects the components of the user interface from the external environment, increasing their longevity - even when the support structure is separated from the vehicle.

The mantle can also improve the security of the transactions between the user and the one or more data communication modules by shielding the transactions from the view of third parties. For example, one of the data communication modules may be require the user to input a personal identification number (PIN). The mantle may be positioned and arranged to contact with the vehicle structure surrounding the open window of the vehicle. The mantle may be arranged to form a seal, at least in part with the vehicle structure surrounding the open window of the vehicle. This can improve the advantageous effects of the mantle, especially with regard to the maintenance of the temperature of the interior of the vehicle. To complement this advantage, the user interface may comprise a heating and/or a cooling system. The user interface may comprise parking indicia for indicating to a user the position in which a vehicle should be parked relative to the user interface. Advantageously, the parking indicia maximises the effectiveness of the user interface, as the vehicle can be aligned by a user to a position that requires minimal compensation by the drive means to adjust the relative position of the support structure and the vehicle. This increases the speed at which the user is able to access the user-interactable components of the user interface.

The mantle may comprise the parking indicia. Preferably, the parking indicia is shaped and arranged to indicate the outline of an open window of the vehicle. This provides a convenient way of indicating to a user how the vehicle should be positioned when parked relative to the user interface.

Preferably, the user interface comprises a resilient portion. Preferably, the resilient portion is positioned to prevent damage to a vehicle in the event of contact between the user interface and the vehicle. The mantle may comprise the resilient portion.

The mantle may be arranged to support at least one or more of the user-interactable components. Preferably, the support structure comprises interior walls. The interior walls may be accessible by the user via the mouth defined by the mantle.

Preferably, the interior walls are arranged to support the one or more user-interactable components. Advantageously, this is an efficient use of space because it maximises the surface area over which user-interactable components can be supported. In the event that manual interaction between the user and the one or more user-interactable components is necessary, it must be acknowledged the user has a limited reach from the open window of the vehicle. Very approximately, this corresponds to a concavity, the surfaces of which are equidistant from the shoulder of the user. Accordingly, it is preferred that the interior walls of the mantle broadly follow the contours of that concavity. Therefore, it is preferable that the interior walls are positioned and arranged to be within the reach of a user from an open window of the vehicle. It is acknowledged that different users sat within different vehicles may have different reaches out though the open window of the vehicle. However, it is assumed that the term 'within the reach of a user' includes within the reach of the majority of the population, more preferably at least 95% of the population and even more preferably 99% of the population.

It should be appreciated that when a user is sat in a vehicle, facing forward, it will be more comfortable for the user to manipulate a manually operable user-interactable component that is at a position that is close to the open window of the vehicle at a position in front of the user. For example, in a car, the user being the driver, this would approximately correspond to a position adjacent the driver-side wing-mirror of the car. This is because the user is able to rest his or her upper arm and bent elbow across the bottom edge of the window opening whilst the user's forearm extends forward to manipulate the user-interactable component as appropriate. Accordingly, it is preferable that user-interactable components, especially those that are to be manually manipulated, are predominately located at a position close to the open window of the vehicle at a position in front of the user.

Preferably, the support structure comprises an arm-rest. Advantageously, an arm-rest can further increase the comfort of a user manually manipulating a user-interactable component of the user interface, especially if the user has to use the component for a prolonged period of time. The arm-rest may comprise a wrist-rest.

Preferably, the position of the one or more user-interactable components is user controllable. Preferably, the position of the one or more user-interactable components is user controllable so as to bring the one or more user interactable components through the open window of the vehicle. The one or more user-interactable components may be positioned relative to the support structure. Advantageously, this user-controllable positioning maximises the ease of use of the user interface, as the user is able to customise the position of the user-interactable components. This can improve the effectiveness and comfort with which the user is able to interact with the one or more user-interactable components. For example, if a user-interactable component is a data communication module in the form of a keyboard, then the user is able to position it on his or her lap within the vehicle to enable the user to sit naturally, facing forward, and use both hands for entering data via the keyboard. Similarly, and by way of example, if the data communication module is in the form of a display screen, it can be positioned in front of the user on the dashboard, or steering wheel.

The user-controllable position of the one or more user-interactable components may be controlled manually. Advantageously, this can allow a user to quickly position the one or more user-interactable components from a location that is within reach - but may be inconvenient - to a more convenient position.

The one or more user-interactable components may comprise support means to facilitate the support of the one or more user-interactable components relative to user. Preferably, the support means comprises a mount to allow the user-interactable components to be mounted relative to the user. For example, the mount may be a steering wheel mount to allow the mounting of the one or more user-interactable components onto a steering wheel of the vehicle. Advantageously, as the steering wheel is positioned directly in front of the user, this provides a particularly convenient location to position the user-interactable components.

The one or more user-interactable components may comprise labels to guide the user as to how a particular user-interactable component is to be operated.

The one or more user-interactable components may comprise position override controls for receiving an input from a user to override the position of the support structure relative to the vehicle. For example, the position override controls may be arranged to receive a user input to move the support structure and the vehicle apart. Advantageously, if the user wishes to leave the vehicle, then this allows the user to do so. Furthermore, if the support structure has been guided to an inappropriate or inconvenient position for the user to access the one or more user-interactable components, then it is possible for the user to remedy this through the position override controls. Advantageously, the position override controls may be located at a position relatively closer to the vehicle than other user-interactable components. The one or more user-interactable components may comprise a beverage dispenser for dispensing beverages such as coffee. The beverage dispenser may comprise a cup dispenser. The beverage dispenser may comprise user-selectable inputs to specify the type of beverage to be dispensed.

The one or more user-interactable components may be a data communication module in the form of a camera. Advantageously, the camera may be directed outwardly from the mouth defined by the mantle so as to capture images and/or video of the user of the vehicle through the open window of the vehicle. The captured images and/or video may be recorded, for example for the purposes of security. The captured images and/or video may be transmitted to a remotely located monitoring station to enable monitoring personnel to remotely monitor the users interaction with the user interface.

The one or more user-interactable components may be a data communication module in the form of a microphone module. The microphone module may be integrated with the camera. The microphone is advantageously directed outwardly from the mouth defined by the mantle so as to capture sounds from the user of the vehicle through the open window of the vehicle. The captured sounds may be recorded, for example for the purposes of security. The captured sounds may be transmitted to a remotely located monitoring station to enable monitoring personnel to remotely monitor the users interaction with the user interface.

The user interface may be arranged to receive control commands from a or the remotely located monitoring station to control the behaviour of the user interface. For example, the relative position between the support structure and the vehicle may be remotely controlled via the remotely located monitoring station via the control commands. If appropriate, the control commands may be also used to control the dispensing of products at the user interface. The user interface may be arranged to receive audio and/or video information from a or the remotely located monitoring station and provide said audio and/or video information to the user. The audio and/or video information may originate from monitoring personnel, and thus can allow the user to be guided as to how to operate the user interface.

The one or more user-interactable components may be a data communication module in the form of a help-request input. Preferably, the help-request input is arranged to generate a prompt for summoning the attention of assistance personnel. The prompt may be a visual and/or acoustic prompt, for example respectively, a flashing light or an alarm. The help-request signal may generate the prompt at a or the remotely located monitoring station. In this case, the monitoring personnel can fulfil the role of assistance personnel by communicating with the user remotely, for example via audio and/or video links between the remotely located monitoring station and the user interface.

The one or more user-interactable components may be a data communication module in the form of a product ordering module for receiving product orders from a user. Preferably, the product ordering module comprises a communication link with an automated product provisioning system. The communication link with the automated product provisioning system may therefore be used to transmit a product order from the product ordering module to the product provisioning system. Advantageously, this allows product orders to be automatically fulfilled. Preferably, the product ordering module is arranged to receive a product order from an electronic device identified with the product ordering user. Generally, this would take the form of a touch-screen electronic display, for example, a tablet-style device akin to an iPad®. Also, it is preferred that the product ordering module comprises the electronic device. However, alternatively, or in addition, the electronic device from which a product order is received may be separate from the user interface. In such a case, the transfer of a product order to the product ordering module may be effected through a wired data connection, a wireless data connection (for example, utilising radio waves), visually and/or acoustically. The separate electronic device used to transfer a product order may be an electronic device personal to the user, for example a mobile device or a device integrated with the vehicle. Advantageously, if a personal device is used, then the user can customise it, and will be familiar with its operation, thereby engendering

confidence in the use of the user interface of the present invention. Advantageously, the product ordering module may be arranged to send an instruction signal to inform operations personnel of a product order to be fulfilled. The instruction signal may be provided in addition to a transmission to the product provisioning system to enable both automatic and manual fulfilment of a product order. For example, if the user interface is provided in the context of a service station, then a product order may relate to the refuelling of the vehicle. Accordingly, either an automatic refuelling machine or operations personnel may be tasked with fulfilling that product order. The product ordering module advantageously permits either - or both - systems to be implemented.

It is advantageous for the electronic device to take the form of a touch-screen electronic display, such as a tablet-style device. Products that are available for order can be displayed on the display, along with product prices - all of which can be dynamically updated. Furthermore, the electronic display can also provide guidance to facilitate the user's use of the user interface. The electronic display may also provide feedback about the status of an order.

The one or more user-interactable components may be a data communication module in the form of a payment module for receiving payment for ordered products.

Preferably, the payment module comprises an electronic payment device such as a card reader and/or cash input devices. The card reader is arranged for reading data cards such as credit cards, and is arranged to authenticate electronic payment, as is known in the art. The electronic payment device may comprise a data input module allowing the user to enter data verifying the user's authority to effect payment for ordered products. Cash input devices may comprise banknote inputs and coin inputs as are known in the art. A cash return device may also be provided.

Age restricted products, such as alcoholic beverages, tobacco products and pornographic material may be available through the user interface. Accordingly, it is preferred that the one or more user-interactable components may be a data

communication module in the form of an age verification system for authorising the sale of restricted items. The age verification system may comprise a scanner for scanning an identification document such as a passport, driving licence or other official document. The scanner may be an iris scanner, or a fingerprint scanner. The age verification system may comprise a camera and/or microphone arranged to transmit images, video and or audio of a user to a remotely located monitoring station at which monitoring personnel can make a determination as to whether a user is above a minimum age. Accordingly, the user interface may be arranged to receive a control command from the remotely located monitoring station authorising the dispensing of age-restricted items. The one or more user-interactable components may comprise a ticket dispenser for dispensing tickets and/or receipts. The one or more user-interactable components may comprise a coin or banknote dispenser for dispensing coins or banknotes. The one or more user-interactable components may comprise a product dispenser for dispensing ordered products, such as packaged products. Preferably, the product dispenser comprises an opening through which ordered products are dispensed to a user. Preferably, the product dispenser comprises a product carrier for carrying the products relative to the user. The product carrier may be user-positionable relative to the support structure of the user interface. Preferably, the position of product carrier is user controllable to bring it through the open window of the vehicle. Advantageously, this allows ordered products to be delivered conveniently into the vehicle. The product carrier may comprise a counter-balance to counteract the effect of the weight of products carried by it. Advantageously, if the position of the product carrier is user controllable manually, then the counter-balance facilitates manual handling of the product carrier and the dispensed products. The product dispenser may comprise a handle to further facilitate manual handling. The product dispenser may comprise a window to allow the dispensed products to be viewed by a user. Advantageously, by providing a window, a user can be alerted to the fact that products have been dispensed.

Preferably, the product dispenser comprises a product delivery path for guiding products dispensed from a product provisioning system to the product carrier.

Preferably, the product delivery path is adjustable to account for relative movement between the product provisioning system and the product dispenser. Advantageously, this allows products to be delivered continuously from a product source (in this case, the product provisioning system) to a product destination (the user) via the product delivery path. This minimises the delay between ordering a product and its delivery, and avoids the time consuming back-and-forth shuttling of a carriage system as described in Kenyon.

Preferably, the product delivery path comprises a flexible chute. Advantageously, this provides a simple and effective way of achieving the position adjustability of the product delivery path. Preferably, the chute feeds products to the product carrier under action of gravity. Again, this advantageously provides a simple, yet effective mechanism for delivering products from the product provisioning system. It is also preferred that the product provisioning system is located a position gravitationally above the product dispenser to effect the gravity-fed delivery. However, it will be understood that a product drive arrangement may be employed instead, or in addition to the gravity-fed arrangement. The one or more user-interactable components may comprise a receptacle dispenser for dispensing receptacles suitable for use in packing together ordered products. For example, the receptacle dispenser may be a plastic bag dispenser. Advantageously, this assists the user in handling multiple ordered and delivered products.

The first aspect of the invention has been described to be an electromechanical user interface for a product ordering system. It should be appreciated that the same electromechanical user interface can be also suitable for a product delivery system, or a combined product ordering and delivery system.

It will be appreciated that the present invention may also extend to a vehicle bay for receiving and accommodating a vehicle, the vehicle bay comprising a user interface according to the first aspect of the present invention.

Furthermore, the present invention may extend to a plurality of vehicle bays, at least one of which comprises a user interface comprising features described in relation to the first aspect of the present invention. In particular, the functions of the present invention may be distributed across multiple user interfaces at different bays. For example, a first user interface may be arranged to receive a product order from a user and then a second user interface may be arranged to dispense the products to fulfil that product order. In such a scenario, a user would typically be guided by the first user interface from the first user interface to the second user interface. Furthermore, this concept also extends to a refuelling scenario in which a product order placed at a first user interface comprises an order for refuelling the vehicle. Accordingly, the first user interface can instruct a user to manoeuvre their vehicle to a refuelling bay to fulfil that refuelling order. Accordingly, the present invention may also extend to a service station comprising refuelling points, bays and user interfaces comprising features as described above.

According to a second aspect of the present invention there is provided a method of fulfilling and/or receiving a product order from a user via an open window of a stationary vehicle, the method comprising the steps of:

providing a user interface comprising one or more user-interactable components supported by a support structure, the user-interactable components being arranged for fulfilling and/or receiving a product order;

determining the position of the open window of the vehicle; and driving the support structure relative to the open window of the vehicle so as to adjust the position of the support structure relative to the vehicle between a first position at which the support structure is spaced from the vehicle and a second position at which the support structure is adjacent to the open window of the vehicle, the second position thereby facilitating user interaction with the one or more user- interactable components.

Preferably, the method comprises the steps of mantling the user-interactable components.

It will be appreciated that features of different aspects of the invention may be combined where context allows. Furthermore, features of the aspects of the invention may constitute further independent inventive aspect. Furthermore methods of providing the functions of any one or combination of the features of the different aspects of the invention may be provided. Furthermore, computer controllers may be provided for controlling and/or receiving inputs from the systems relating to aspects of the present invention, and/or for carrying out methods relating to aspects of the present invention.

Detailed Description of the Preferred Embodiments Figure 1 is a partial schematic perspective view of an electromechanical user interface 20 for a product ordering and delivery system 1 according to a first embodiment of the present invention. The product ordering and delivery system 1 comprises the user interface 20 at which product are ordered and received by a user, and a product provisioning system 1 1 from which ordered products are provided. The product ordering and delivery system 1 also comprises a product delivery chute 15, an auxiliary spur chute 17 and an auxiliary product dispenser 12. The user interface 20 is connected to the product provisioning system 11 via the product delivery chute 15. The chute 15 is connected to the auxiliary spur chute 17 that leads to the auxiliary product dispenser 12.

The user interface 20 is located adjacent a vehicle bay 14. The other components of the product ordering and delivery system 1 are disposed about the vehicle bay 14 so that a vehicle can easily be driven in and out of the bay 14.

The user interface 20 comprises a mantle 10. To aid clarity, it should be noted that the mantle 10 is not shown in any of the other drawings, as its presence makes it difficult to see the other components of the user interface 20.

Referring now to Figure 1a, the same view is shown of the electromechanical user interface 20 as in Figure 1 , but without the mantle 10. The user interface 20 comprises a plurality of user-interactable components, generally indicated by reference numeral 22, and as will be expanded on below. The user interface also comprises a support structure 24, a drive means 26 and a detector 28.

An overview of the operation of the user interface 20 is described with reference to Figure 2. Here, the same perspective view as Figure 1 a is shown, but for a vehicle 6 being positioned within the bay 14, the vehicle 6 having been driven into the bay 14, and parked there by a user 8. Here, the user interface 20 is in an extended configuration triggered by the presence of the vehicle 6 within a bay 14.

As the user 8 drives the vehicle 6 into the bay 14, the detector 28 determines the position of the driver-side window 7 of the vehicle 6. The detector 28 sends instructions to the drive means 26 so as to adjust the position of the support structure 24 relative to the vehicle 6. In particular, the support structure 24 is moved from a first retracted position spaced from the vehicle (as shown in Figures 1 and 1 a), to a second extended position adjacent to the open window 7, the second position thereby facilitating user interaction with the one or more user-interactable components 22 of the user interface 20.

For the avoidance of doubt, although the mantle 10 is not shown in Figure 2, it should be understood that it is present, and defines a mouth through which the user- interactable components 22 are manually accessible by the user 8. Furthermore, the user interface 20 being in the second extended position means that the mantle 10 is in contact with the vehicle structure surrounding the open window 7 of the vehicle 6. In view of this, the mantle 10 comprises a resilient seal 100 that is arranged to contact with the vehicle 6 without causing damage to the vehicle 6. As will be described, the mantle 10 advantageously improves the interaction between the user 8 and the user- interactable components 22.

Referring to Figure 3, the user interface 20 comprises a tubular frame 30. Behind and through it is the support structure 24 that supports a plurality of components of the user interface 20, including the user-interactable components 22. The tubular frame 30 is shaped to mimic the outline of the open window of the vehicle 6 as so provides a convenient way of guiding the user 8 to align the vehicle 6 with the user interface 20. The tubular frame 30 supports position override controls 32, 34, 36, which allow the user 8 to override the positioning of the support structure 24 relative to the vehicle 6.

The support structure 24 of the user interface 20 comprises interior walls 25 which support the majority of the user-interactable components 22. Generally, the user interactable components 22 comprise a beverage dispenser 40, a camera 50, a microphone and speaker module 55, a help-request input 58, a product-ordering module having a touch-screen electronic display 60, a payment module 70, a cash- output module 80, a receipt and coin dispenser 85, a plastic bag dispenser 99 and a product dispenser 90. As can be seen in Figure 3, some of the user-interactable components 22 comprise labels to guide a user 8 as to how the user should operate or otherwise interact with the respective user-interactable components 22.

The beverage dispenser 40 comprises a cup dispenser 42 and beverage dispensing controls 44. The payment module 70 comprises a payment card reader 72, a PIN entry keypad 74, a banknote input slot 76 and a coin input slot 78. The cash output module 80 comprises a banknote output slot 86.

Referring to Figure 4, the touch-screen electronic display 60 can be picked up by a user 8, and pulled into the vehicle 8. To the rear of the electronic display 60 is a mount which allows the electronic display 60 to be mounted onto the steering wheel of the vehicle 8 to permit hands-free operation of the electronic display 60 during product ordering. The electronic display is tethered to the user interface 20 by way of cable 62 that supplies data and power to the electronic device 60. The electronic display 60 displays products that are available for order along with product prices. In use, the user 8 interfaces with the electronic display to select desired products, and thus to place a product order. The cable 62 is used to establish a communication link via the user interface 20 to the automated product provisioning system 11. Accordingly, a product order placed via the touch-screen display 60 can be transmitted to the product provisioning system 11. Referring back to Figure 3, one of the position override controls 32, 34, 36 are arranged to receive a user input to move the support structure 24 away from the vehicle 6. Advantageously, if the user 8 wishes to leave the vehicle 6, then this allows the user 8 to do so. Furthermore, if the support structure 24 has been guided to an inappropriate or inconvenient position for the user 8 to access the user-interactable components 22, then it is possible for the user 8 to remedy this through the position override controls 32, 34, 36. Advantageously, the position override controls 32, 34, 36 are located on the tubular frame 30, and so are at a position relatively closer to the vehicle 6, and so the user 8, than other user-interactable components 22. The camera 50 is a video camera directed outwardly from the support structure 24 to capture video footage of the user 8 of the vehicle 6 through the open window 7 of the vehicle. The captured video footage is recorded for the purposes of security. The captured video is also transmitted to a remotely located monitoring station to enable monitoring personnel to remotely monitor the users interaction with the user interface 20.

The camera 50 works in conjunction with the microphone and speaker module 55. The microphone of the microphone and speaker module 55 permits audio corresponding to the video footage to be transmitted to the remotely located monitoring station. The speaker of the microphone and speaker module 55 enables audio to be transmitted back to the user interface 20 from the monitoring station. Thus the camera 20 and microphone and speaker module 55 facilitates communication between the personnel at the remotely located monitoring station and the user 8, if so required by the user. To this end, the user 8 can use the help-request input 58 to summon the attention of the monitoring personnel.

The product dispenser 90 comprises a body 93 shaped like a tube. The end of the tube-like body is covered by a circular end-cap 91. A handle 92 is fitted to the cap 91 of the product dispenser 90 for facilitating manual manipulation of the product dispenser 90. A window 94 is also provided on the cap 91 allowing viewing into the interior of the tube-like body 93 of the product dispenser 90. As shown in Figure 3, the body 93 is normally stowed within the support structure 22, and therefore cannot be seen. However, as shown Figure 5, when a user 8, pulls the handle 92, the product dispenser 90 is able to extend out from the support structure 22 and into the vehicle 6, exposing the body 93. A curved hatch 95 formed in the sidewalls of the tube-like body 93 defines an opening in the product dispenser 90 and through which products can be dispenser to the user 8. The body 93 serves as a product carrier for carrying products dispensed to it until a user 8 is ready to retrieve them. The body 93 of the product dispenser 90 is counterbalanced to counteract the effect of the weight of products within it. Thus, this facilitates manual handling of the product dispenser 90, allowing a user to easily pull it out and push it back into the support structure 22, without being overly affected by the weight of the products within it.

The aforementioned product delivery chute 15 defines a product delivery path that leads from the product provisioning system 11 to the body 93 of the product dispenser 90. The product delivery chute 15 is flexible, and so is adjustable to account for relative movement between the product provisioning system 11 and the product dispenser 90. This allows products to be delivered continuously from the product provisioning system 1 1 to the user 8 via the product delivery path, despite the change in position of the user interface 20 between the first retracted position (as shown in Figures 1 and 1 a) to the second extended position (as shown in Figures 2 and 5).

A more detailed description of the use and operation of the user interface 20 will now be given.

As stated, the first retracted position of the user interface 20 is shown in Figures 1 and 1a. In this position, the user interface 20 is configured such that the support structure 24 is retracted and so is at a position spaced from the bay 14 and any vehicle 6 occupying the bay 14. When in this position, the detector 28 by way of a video camera, monitors the area in and around the bay 14 to determine whether a vehicle 6 is approaching the bay 14 and/or whether the vehicle 6 is stationary within the bay 14. The detector 28 is linked to a processor capable of making such a determination, for example via image processing of the images received from the video camera.

Furthermore, the detector 28 is also arranged to determine the type of vehicle 6 and, moreover, the height of the driver-side window 7 of the vehicle 6 from the floor. Such a determination may be made even when the vehicle is moving as it will be appreciated that the vertical height of the window 7 from the floor will not change significantly between when the vehicle 6 is in motion, and when the vehicle 6 is stationary. The making of such a determination (for example, via image processing) is known in the art, and so will not be discussed further. Nonetheless, information relating to the height of the window 7 of the vehicle 6 is processed and passed to the drive means 26 to alter the height of the support structure 24 in preparation for the arrival of a vehicle 6 into the bay 14.

It should be noted that only a single detector 28 is shown in the figures at a position above and to the rear of the bay 14. However, this is purely schematic, and in fact there may be multiple detectors 28 located at various positions relative to the bay 14. Generally, the ideal position of the detector 28 (or detectors) may vary under different conditions and so would typically be determined empirically. However, it is anticipated that an effective position of a detector 28 is that which provides a viewpoint similar to the viewpoint of the support structure 24. In light of this, the camera 50 that is mounted on the support structure 24 may be used. Accordingly, the camera 50 can serve a dual purpose in that it can be used for the purposes of controlling the position of the support structure 24 as well as providing a means by which a user 8 and monitoring personnel can communicate. It should also be appreciated that the detector 28 may comprise other sensors for the purpose of correctly guiding the support structure 24 relative to a vehicle 6. Nonetheless, as a vehicle approached, the height of the support structure 24 can be altered so that the lower edge of the tubular frame 30 corresponds with the lower edge of the window 7 of the vehicle 6.

The user 8 driving the vehicle 6 is guided to stop the vehicle at approximately the correct position along the tubular frame 30, as it has the appearance of a window outline. Accordingly, the tubular frame 30 serves as a parking position indicator for the user. The tubular frame 30 is typically a bright colour to make it stand.

Referring to Figure 2, after the vehicle 6 is stationary within the bay 14, as determined by the detector 28, the detector 28 also makes a determination as to whether the window 7 of the vehicle 6 is open. This determination can be made via a number of ways known in the art. For example, the image processor of the detector may utilise the reflectance of the window 7, for example relative to a predetermined light source.

If the window 7 is not open, then the user 8 may be prompted to open the window 7. This can take place at the same time as, or before the support structure 24 is driven by the drive means 26 in a horizontal direction from the first position, retracted away from the bay 14, to an extended position, extended into the bay 14 and towards the vehicle 6. It should be noted that if the detector 28 determines vehicle movement, then the drive means 26 is controlled to immediately retract the support structure 24 to prevent damage to it or the vehicle. The detector 28 is able to also control the drive means 26 in a way that accounts for peculiarities of the vehicle 6 and the structure and shape of the vehicle 6. For example, the detector 28 is able to account for the position of a wing-mirror of the vehicle 6. Similarly, the detector 28 is able to control the drive means 26 if an unusual vehicle is detected within the bay 14 - for example a motorcycle, or a convertible car with its roof stowed. In such cases, it should be appreciated that the support structure 24 is guided to a position close to the user that eases his or her use of the user interface 20. If the detector 28 determines an irregularity for which it is not

programmed - for example, a mounted horse within the bay 14 - an alert can be sent to monitoring personnel who may be able to override the operation of the drive means 26, or otherwise take the appropriate action.

Nonetheless, assuming there is a window opening, the resilient seal 100 of the mantle 10 abuts against the side of the vehicle 6 as the support structure 24 is guided into position by the detector 28. In doing so, the resilient seal 100, seals about the window opening.

It will be appreciated that different vehicles will have different contours in the region of their side window. It is intended that the resilient seal 100 can conform to a range of different vehicle contours so as to provide an effective seal about the window opening. However, it will be appreciate that, in alternative arrangements, the mantle 10 itself may be deformable and or deflectable in a manner that ensures that it is able to effectively fit relative to a range of different vehicle contours.

Referring to Figures 3 and 4, after the mantle 10 is positioned about the window 7, the support structure 24, and moreover, the user-interactable components 22 it supports are brought into easy reach of the user. As stated previously, the majority of the user- interactable components 22 are in the form of data communication modules arranged to communicate information between the user 8 and the user interface 20 relating to products and/or product orders.

It should be noted that the vehicle window opening 7 is limited in size. In the present example, the size is approximately 70cm in width along the bottom edge of the window opening, and approximately 40cm from the bottom edge, to the top-most edge of the window opening. Accordingly, a limited space is provided through which a user 8 can access functions associated with user interface 20. It will therefore be appreciated that the interior walls 25 of the support structure 24 are highly effective in maximising the use of this limited space as they can be utilised in supporting user-interactable components 22 of the user interface 20. Approximately, the surface area provided as a result of employing these interior walls 25 is over 1 square metre. By way of comparison, it is estimated that the user interface described in Kenyon - which does not employ interior walls - provides a useable surface area of less than 0.25 square metres. Accordingly, the user is able to reach through the mouth defined by the mantle 10 to make use of a wide variety, and relatively large number of functions supported by the user interface 20.

Referring to Figure 4, the user 8 retrieves the touch-screen electronic device 60 and takes it into the vehicle 6. As mentioned, the mount of the electronic device 60 allows it to hook onto the steering wheel of the vehicle 6. Accordingly, the user 8 is able to sit comfortably facing forwards when ordering products instead of having to twist uncomfortably out of the side window. The electronic device 60 presents the user with product ordering options via images of the orderable products, quantity information, price, product categories and so forth.

If the user 8 is unsure about how to operate the user interface 20, then the user 8 can operate the help-request input 58. This sends a signal to monitoring personnel who can assist the user 8 via the microphone and speaker module 55. Advantageously, the mantle 10 improves this audio communication, as the mantle 10 is able to direct the sound and provide a shield against external noise.

Furthermore, the mantle 10 can improve the comfort of the user 8 interacting with the user interface 20 as the user 8 is protected from the external environment. In addition the mantle 10 minimises heat transfer between the interior of the vehicle and the external environment, maintaining the effect of a vehicle's heating or air-conditioning systems. After the user has ordered products via the electronic device 60, the user is prompted to pay for those ordered products. The user is directed by instructions on the electronic device 60 to provide payment via the payment module 70. The user 8 is therefore able to make payment by credit card or cash by using the payment card reader 72 and PIN entry keypad 74 or banknote input slot 76 and cash slot 78 as appropriate. The mantle 10 improves the security of the transactions between the user and the PIN entry keypad 74 by shielding them from the view of third parties.

After payment has been authorised, a receipt is printed and products are dispensed from the product provisioning system 11 to the product dispenser 90. It will be appreciated that it may not be physically possible or practical to accommodate a large quantity of products within the product dispenser 90. Accordingly, if a large quantity of products have been ordered, the product provisioning system 11 is able to direct the products to the auxiliary product dispenser 12 that is located at the rear of the bay 14, close to the boot of the vehicle 6. In such a case, the user 8 will be directed by the electronic device 60 to use the position override controls 32, 34, 36 to enable the user to leave the vehicle to load the ordered products into the boot of the vehicle 6.

Alternatively, after the products have been dispensed, the support structure 24 may automatically retract to allow a user to leave the vehicle 6.

After products have been ordered and delivered, a user is able to drive the vehicle 6 away, freeing the bay 14 for another vehicle.

In alternatives, the electronic display 60 may be positioned relative to the support structure in other ways. For example, with reference to Figure 6, the electronic display 60 may be extended through the open window of the vehicle 6 via an extendible arm 162.

In other alternatives, a different type of product dispenser may be provided. For example, with reference to Figures 9a and 9b products may be delivered via container- carrying conveyor belt. Alternatively, with reference to Figures 10a and 10b, ordered products may be delivered via product dispensing hatch.

It should also be noted that, in other alternatives, products might be ordered from one location, and then delivered at another. In such a case, the features and functions of the above-mentioned user interface according to first embodiment are distributed. In particular, the features and functions for the ordering of products may be located at one user interface, and the features and functions for the delivery of those ordered products is located at a different user interface. Figure 8 illustrates an example this distributed model. Figure 8 is a schematic partial perspective view of a petrol station comprising a plurality of user interfaces according to alternative embodiments of the present invention to that shown in Figures 1-7, 9a, 9b, 10a and 10b. Specifically, two user interfaces 200 according to a second embodiment are provided for ordering products and paying for them. Another user interface 300 according to a third embodiment is provided for the delivery of the products ordered at the product-ordering user interfaces 200. Each product-ordering user interface 200 and an associated bay 214 define an order and payment station 2. The product-delivery user interface 300 and an associated bay 314 define a delivery station 3.

The product-ordering user interfaces 200 comprise almost all of the same features as the first embodiment, but for features and functions required for the dispensing of ordered products. Notably, the product-ordering user interfaces 200 do not have the product dispenser 90 of the first embodiment, and are not physically connected to a product provisioning system 1 1. Similarly, the product-delivery user interface 300 does not have the product ordering module or payment module 70, but is provided with a product dispenser that is connected to a product provisioning system (not shown) supported by a frame 110 via a flexible, spiralled product delivery chute 15.

In use, a user 8 guides their vehicle 6 to an order and payment station 2 to place a product order at one of the product-ordering interfaces 200. After products have been ordered and paid for, the user is prompted to drive to the delivery station 3 at which the products are dispensed.

If a user has ordered fuel as well as packaged products, this can be provided at a fuel station 4. The ordering and payment stations 2, delivery station 3 and fuel station 4 are separate from one another and so ordering and delivery of packaged products and fuel can be provided to multiple vehicles in parallel, leading to a gain in the efficiency of the petrol station.
