Method and apparatus for providing virtual touch interaction in the drive-thru

Abstract

The present invention is a method and apparatus for providing an enhanced automatic drive-thru experience to the customers in a vehicle by allowing use of natural hand gestures to interact with digital content. The invention is named Virtual Touch Ordering System (VTOS). In the VTOS, the virtual touch interaction is defined to be a contact free interaction, in which a user is able to select graphical objects within the digital contents on a display system and is able to control the processes connected to the graphical objects, by natural hand gestures without touching any physical devices, such as a keyboard or a touch screen. Using the virtual touch interaction of the VTOS, the user is able to complete transactions or ordering, without leaving the car and without any physical contact with the display. A plurality of Computer Vision algorithms in the VTOS processes a plurality of input image sequences from the image-capturing system that is pointed at the customers in a vehicle and performs the virtual touch interaction by natural hand gestures. The invention can increase the throughput of drive-thru interaction and reduce the delay in wait time, labor cost, and maintenance cost.

Benefits of technology

[0013]In an exemplary embodiment, the VTOS can be comprised of a housing (enclosure), a plurality of the image-capturing system, a display system, a processing and controlling system, a lighting system, a drive-thru ceiling structure, and a sound system (hidden in the enclosure). The processing and controlling system is connected to the image-capturing system, the display system, and the sound system. The image-capturing system is defined to be a system with plurality of image-capturing devices, such as cameras, frame grabbers and all relevant peripherals, in the VTOS. Lighting system and drive-thru ceiling structure help the VTOS to process the user detection and the contact-free interaction by helping computer vision technology operate more reliably. The lighting system and the drive-thru ceiling structure is not the essential part of the VTOS, but they belong to the VTOS as the environmental set up, in a broader concept.

[0022]The VTOS detects the vehicle and the position of the vehicle window, which is used to define the Maximum Interaction Range Volume and the Optimal Interaction Volume, which is the region in real world 3D space that is tracked and mapped to find the hand location. The maximum interaction range volume and the optimal interaction volume of the VTOS are virtual space, which change according to the physical dimension of the driver and the vehicle. Since the volumes change according to the position of the driver and vehicle, some degree of freedom for the motion is possible. This is helpful and necessary for the contact-free interaction process by the VTOS, because the vehicles can be parked in random position within the vicinity of the VTOS units.

[0028]The location and number of the image-capturing system and the location of the display system for the present invention could be in multiple places around the vehicle as long as the driver is able to see the display system and the VTOS can see the driver's hand motion. The system can track the hand of the user when it is located outside or inside the vehicle, therefore giving the option to the user of interacting with the display without opening the vehicle window.

[0030]The VTOS is able to collect data using computer vision algorithms and analyze the results of the ordered items and customer behaviors in selection processes, which can be saved after customers finish the interaction of giving orders and other transactions.

[0035]So far a single housing unit model of the VTOS is summarized. However, the VTOS can also comprise multiple housing units, which are organized in pipeline and / or parallel in order to perform multiple transactions at the same time, similar to the schemes of a gas station. Overall, this model increases the throughput of the drive-thru, decreasing the average wait time per customer. For the case of certain transactions, such as the bank transaction, which could specifically require human attendant's involvement, the design of the VTOS could be modified in a way such as to minimize the number of attendants.

Problems solved by technology

Inconsistent speed, accuracy and customer experience, which can occur throughout the traditional drive-thru process, pose unique challenges for corporate planners.

Miscommunications due to language barriers, speaker or microphone malfunction, or just plain poor attitudes can combine to create a very unpleasant customer experience.

This traditional drive-thru system has inherent inefficiency of wait time in the interaction process.

However, this method results in having more attendants with the three windows and relevant building construction cost.

This method is also not easily adaptable to the other type of drive-thru interaction process than that of the quick-service restaurant.

While they have interesting and versatile approaches to the drive-thru process, the customers in the vehicle need to have mobile access to the network, which could require extra cost and burden to the customer.

Unless enough people within the local area have mobile access to the network mentioned in the U.S. Pat. No. 6,026,375 of Hall et al., there is a possibility that the network might not be utilized.

Also, signals of mobile access, such as cell phones, weaken, depending upon the location, weather condition, etc.

Finally, since the interface is not natural (i.e., the user has to select from a large menu using the alpha-numeric keypad), there are issues of delay.

While this approach tries to improve the drive-thru interaction using the video communication system in addition to the conventional voice only drive-thru system, allowing the customer to maintain eye-to-eye visual contact with the attendant located within the restaurant, the approach is still not able to solve the delay of interaction problem for the plurality of customers and vehicles.

While the suggested method increases the throughput of the interaction process, it also results in hiring more attendants or order-takers for each station, thus increasing labor costs.

However, these systems result in maintenance and hygiene issues since the drivers touch the system physically.

The touch-screen display is fixed and, therefore, cannot adapt to the various sizes of vehicles and arm lengths of people.

This would be devastating to the fast food drive-thru industry with the increase in order time alone.

This also causes difficulty in parking the vehicle, as it needs to be close to the system as possible in order for the driver to be able to touch the screen, stretching the hand to the device.

This is ergonomically inappropriate because it is not only uncomfortable to the driver but also could cause damage to the system.

If the driver has to step out of the vehicle to use the automatic systems, this will result in more delay and inconvenience to the customer.

Other solutions include a device that the user can put inside the vehicle, such as a keypad, or track ball; however, these also involve disadvantages of hygienic issues and durability.

However, in most cases, the driver will feel comfortable in interacting with the VTOS within the optimal interaction volume because of the physical limitation in the range of movement a driver can reach with his or her hand.
