## Background
BACKGROUND INFORMATION
1. Field of the Disclosure
The present invention relates generally to providing a shopping list to a consumer that can be created electronically. In particular, a consumer can create a shopping list electronically and the electronic shopping list can be automatically updated in response to one or more signals that are transmitted through an augmented reality device worn by the consumer.
2. Background
Some retail stores extend across tens of thousands of square feet and offer thousands of items for sale. Many consumers visit such retail stores when shopping for a diverse set of items such as groceries, office supplies, and household wares. Typically, these stores can have dozens of aisles and/or departments. Accordingly, traversing these aisles looking for specific items may be a challenging experience. Shopping lists can assist a consumer in focusing on the items to purchase, to complete a shopping trip successfully and efficiently. However, shopping lists can be difficult to manage while the consumer is traversing the store looking for items and avoiding other consumers. The consumer often needs to grasp and consider items, making it difficult to maintain the shopping list in-hand and even more difficult to maintain both the shopping list and a writing instrument in-hand.

Accordingly, the present disclosure may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.), or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “module” or “system.” Furthermore, the present disclosure may take the form of a computer program product embodied in any tangible medium of expression having computer-usable program code embodied in the medium.
Embodiments of the present disclosure can assist a consumer shopping in a retail store. An embodiment of the present disclosure can assist a consumer in managing a shopping list to help the consumer shop more efficiently. An embodiment of the present disclosure can help reduce the stress that can arise while keeping track of items purchased and items acquired, and thus make the shopping trip more enjoyable.
A shopping list management system according to some embodiments of the present disclosure can be operable to receive one or more shopping list signals from an electronic computing device in order to establish a shopping list for a consumer. A shopping list can include a plurality of items that are offered for sale in a retail store. The shopping list can be completed and transmitted to a commerce server of the shopping list management system. The shopping list can be transmitted as a single shopping list signal, wherein a “single” shopping list signal contains the identities of a plurality of items. Alternatively, the shopping list can be established item-by-item with a plurality of shopping list signals, wherein each item is individually communicated in a shopping list signal to the commerce server.
The shopping list can be generated with an electronic computing device possessed by the consumer. An electronic computing device used by a consumer can be a laptop computer, a desktop computer, a smart-phone, a tablet, an e-reader, or any other electronic computing device operable to generate and transmit a shopping list signal.
A shopping list management system according to some embodiments of the present disclosure can be operable to receive signals from an augmented reality device worn by a consumer as the consumer shops in the retail store. The one or more signals can contain information that indicates that the consumer has placed one of the items on the shopping list in a shopping container such as a shopping cart or basket. For example, in some embodiments of the disclosure, a video signal can be transmitted from the augmented reality device and received by a commerce server. The video signal can contain one or more frames in which a consumer's hand is visible placing an item in a shopping container, wherein the item is an item on the shopping list.
In some embodiments of the present disclosure, other signals generated by the augmented reality device can be analyzed to complement the analysis of a video signal. For example, an augmented reality device can be configured to transmit signals indicative of the consumer's position within a retail store and also the orientation of the consumer's head. The position signal can be assessed in conjunction with the video signal to confirm the identity of the item being placed in the shopping container; the item detected in the video signal should be an item proximate to the position of the consumer that is indicated by the position signal. The orientation signal can be assessed in conjunction with the video signal to confirm the identity of the item being placed in the shopping container; the item detected in the video signal should be an item disposed on a shelf consistent with the orientation of the consumer's head when the video signal was captured.
A shopping list management system according to some embodiments of the present disclosure can be operable to modify the shopping list when it is determined that the consumer has placed an item from the shopping list into a shopping container. In some embodiments of the present disclosure, the modification of the shopping list occurs automatically. For example, a shopping list management system can remove the item placed in the shopping container from the shopping list without requiring an additional command or prompt from the consumer.
Embodiments of the present disclosure provide numerous benefits to consumers. Embodiments of the present disclosure allow a consumer to execute a shopping list while freeing the consumer's hands for other purposes. Also, in some embodiments of the present disclosure, the shopping list can be manipulated without speaking. A retail store can include numerous consumers speaking and other sources of noise that can compromise the effectiveness of a shopping list manipulated through voice commands. Some embodiments of the present disclosure can allow the consumer to manage a shopping list without communicating commands verbally.
FIG. 1 is a schematic illustrating a shopping list management system 10 according to some embodiments of the present disclosure. The shopping list management system 10 can implement a computer-implemented method that includes the step of receiving, with a commerce server 12, one or more shopping list signals from a consumer. A single shopping list signal can contain a shopping list. A shopping list can be a plurality of items offered for sale at a retail store that the consumer intends to purchase. Alternatively, a shopping list can be created item-by-item, wherein an individual signal for each item is communicated to the commerce server 12 and the commerce server 12 aggregates the items into a shopping list.
The one or more shopping list signals can be communicated to the commerce server 12 with an electronic computing device possessed by the consumer. The one or more shopping list signals can be communicated from a location that is remote from the retail store or that is within the retail store. The one or more shopping list signals can also be communicated from a kiosk located within the retail store, wherein the kiosk houses an electronic computing device. “Kiosk” can thus be defined in a non-dictionary definition manner. The one or more shopping list signals can also be communicated with an augmented reality device worn by the consumer, such as a head mountable unit 14.
The head mountable unit 14 can be worn by a consumer while the consumer is shopping within the retail store. In the illustrated embodiment of FIG. 1, the exemplary head mountable unit 14 includes a frame 16 and a communications unit 18 supported on the frame 16.
Signals transmitted by the head mountable unit 14 and received by the commerce server 12, and vice-versa, can be communicated over a network 20. As used herein, the term “network” can include, but is not limited to, a Local Area Network (LAN), a Metropolitan Area Network (MAN), a Wide Area Network (WAN), the Internet, or combinations thereof. Embodiments of the present disclosure can be practiced with a wireless network, a hard-wired network, or any combination thereof.
The head mountable unit 14 can transmit one or more signals to the commerce server 12 over the network 20. A video signal can be generated by a camera 42 of the head mountable unit 14 and transmitted to the commerce server 12. The video signal can capture a field of view aligned with the consumer's field of view. Thus, the commerce server 12 can “see” what the consumer sees. The commerce server 12 can detect when an item is placed in a shopping container when the consumer is viewing the placement of an item in the shopping container. When the commerce server 12 detects that an item has been placed in a shopping container, the commerce server 12 can remove that item from the consumer's shopping list. The consumer could build the shopping list through the head mountable unit 14. For example, the consumer might state “create shopping list, add milk, add eggs, add cheese, add bread.” In this case, the list could be stored locally and accessed locally when being executed.
FIG. 2 is a block diagram illustrating exemplary components of the communications unit 18. The communications unit 18 can include a processor 40, one or more cameras 42, a microphone 44, a display 46, a transmitter 48, a receiver 50, one or more speakers 52, a direction sensor 54, a position sensor 56, an orientation sensor 58, an accelerometer 60, a proximity sensor 62, and a distance sensor 64.
The processor 40 can be operable to receive signals generated by the other components of the communications unit 18. The processor 40 can also be operable to control the other components of the communications unit 18. The processor 40 can also be operable to process signals received by the head mount unit 14. While one processor 40 is illustrated, it should be appreciated that the term “processor” can include two or more processors that operate in an individual or distributed manner.
The head mount unit 14 can include one or more cameras 42. Each camera 42 can be configured to generate a video signal. One of the cameras 42 can be oriented to generate a video signal that approximates the field of view of the consumer wearing the head mountable unit 14. Each camera 42 can be operable to capture single images and/or video and to generate a video signal based thereon. The video signal may be representative of the field of view of the consumer wearing the head mountable unit 14.
In some embodiments of the disclosure, cameras 42 may be a plurality of forward-facing cameras 42. The cameras 42 can be a stereo camera with two or more lenses with a separate image sensor or film frame for each lens. This arrangement allows the camera to simulate human binocular vision and thus capture three-dimensional images. This process is known as stereo photography. The cameras 42 can be configured to execute computer stereo vision in which three-dimensional information is extracted from digital images. In such embodiments, the orientation of the cameras 42 can be known and the respective video signals can be processed to triangulate an object with both video signals. This processing can be applied to determine the distance that the consumer is spaced from the object. Determining the distance that the consumer is spaced from the object can be executed by the processor 40 or by the commerce server 12 using known distance calculation techniques.
Processing of the one or more, forward-facing video signals can also be applied to determine the identity of the object. Determining the identity of the object, such as the identity of an item in the retail store, can be executed by the processor 40 or by the commerce server 12. If the processing is executed by the commerce server 12, the processor 40 can modify the video signals limit the transmission of data back to the commerce server 12. For example, the video signal can be parsed and one or more image files can be transmitted to the commerce server 12 instead of a live video feed. Further, the video can be modified from color to black and white to further reduce transmission load and/or ease the burden of processing for either the processor 40 or the commerce server 12. Also, the video can cropped to an area of interest to reduce the transmission of data to the commerce server 12.
In some embodiments of the present disclosure, the cameras 42 can include one or more inwardly-facing camera 42 directed toward the consumer's eyes. A video signal revealing the consumer's eyes can be processed using eye tracking techniques to determine the direction that the consumer is viewing. In one example, a video signal from an inwardly-facing camera can be correlated with one or more forward-facing video signals to determine the object the consumer is viewing.
The microphone 44 can be configured to generate an audio signal that corresponds to sound generated by and/or proximate to the consumer. The audio signal can be processed by the processor 40 or by the commerce server 12. For example, verbal signals can be processed by the commerce server 12 such as “this item appears interesting.” Such audio signals can be correlated to the video recording.
The display 46 can be positioned within the consumer's field of view. Video content can be shown to the consumer with the display 46. The display 52 can be configured to display text, graphics, images, illustrations and any other video signals to the consumer. The display 46 can be transparent when not in use and partially transparent when in use to minimize the obstruction of the consumer's field of view through the display 46.
The transmitter 48 can be configured to transmit signals generated by the other components of the communications unit 18 from the head mountable unit 14. The processor 40 can direct signals generated by components of the communications unit 18 to the commerce sever 12 through the transmitter 48. The transmitter 48 can be an electrical communication element within the processor 40. In one example, the processor 40 is operable to direct the video and audio signals to the transmitter 40 and the transmitter 48 is operable to transmit the video signal and/or audio signal from the head mountable unit 14, such as to the commerce server 12 through the network 20.
The receiver 50 can be configured to receive signals and direct signals that are received to the processor 40 for further processing. The receiver 50 can be operable to receive transmissions from the network 20 and then communicate the transmissions to the processor 40. The receiver 50 can be an electrical communication element within the processor 40. In some embodiments of the present disclosure, the receiver 50 and the transmitter 48 can be an integral unit.
The transmitter 48 and receiver 50 can communicate over a Wi-Fi network, allowing the head mountable device 14 to exchange data wirelessly (using radio waves) over a computer network, including high-speed Internet connections. The transmitter 48 and receiver 50 can also apply Bluetooth® standards for exchanging data over short distances by using short-wavelength radio transmissions, and thus creating personal area network (PAN). The transmitter 48 and receiver 50 can also apply 3G or 4G, which is defined by the International Mobile Telecommunications-2000 (IMT-2000) specifications promulgated by the International Telecommunication Union.
The head mountable unit 14 can include one or more speakers 52. Each speaker 52 can be configured to emit sounds, messages, information, and any other audio signal to the consumer. The speaker 52 can be positioned within the consumer's range of hearing. Audio content transmitted by the commerce server 12 can be played for the consumer through the speaker 52. The receiver 50 can receive the audio signal from the commerce server 12 and direct the audio signal to the processor 40. The processor 40 can then control the speaker 52 to emit the audio content.
The direction sensor 54 can be configured to generate a direction signal that is indicative of the direction that the consumer is facing. The direction signal can be processed by the processor 40 or by the commerce server 12. For example, the direction sensor 54 can electrically communicate the direction signal containing direction data to the processor 40 and the processor 40 can control the transmitter 48 to transmit the direction signal to the commerce server 12 through the network 20. By way of example and not limitation, the direction signal can be useful in determining the identity of an item(s) visible in the video signal, as well as the location of the consumer within the retail store.
The direction sensor 54 can include a compass or another structure for deriving direction data. For example, the direction sensor 54 can include one or more Hall effect sensors. A Hall effect sensor is a transducer that varies its output voltage in response to a magnetic field. For example, the sensor operates as an analog transducer, directly returning a voltage. With a known magnetic field, its distance from the Hall plate can be determined. Using a group of sensors disposing about a periphery of a rotatable magnetic needle, the relative position of one end of the needle about the periphery can be deduced. It is noted that Hall effect sensors can be applied in other sensors of the head mountable unit 14.
The position sensor 56 can be configured to generate a position signal indicative of the position of the consumer within the retail store. The position sensor 56 can be configured to detect an absolute or relative position of the consumer wearing the head mountable unit 14. The position sensor 56 can electrically communicate a position signal containing position data to the processor 40 and the processor 40 can control the transmitter 48 to transmit the position signal to the commerce server 12 through the network 20.
Identifying the position of the consumer can be accomplished by radio, ultrasound or ultrasonic, infrared, or any combination thereof. The position sensor 56 can be a component of a real-time locating system (RTLS), which is used to identify the location of objects and people in real time within a building such as a retail store. The position sensor 56 can include a tag that communicates with fixed reference points in the retail store. The fixed reference points can receive wireless signals from the position sensor 56. The position signal can be processed to assist in determining one or more items that are proximate to the consumer and are visible in the video signal. The commerce server 12 can receive position data and identify the location of the consumer in some embodiments of the present disclosure.
The orientation sensor 58 can be configured to generate an orientation signal indicative of the orientation of the consumer's head, such as the extent to which the consumer is looking downward, upward, or parallel to the ground. A gyroscope can be a component of the orientation sensor 58. The orientation sensor 58 can generate the orientation signal in response to the orientation that is detected and communicate the orientation signal to the processor 40. The orientation of the consumer's head can indicate whether the consumer is viewing a lower shelf, an upper shelf, or a middle shelf.
The accelerometer 60 can be configured to generate an acceleration signal indicative of the motion of the consumer. The acceleration signal can be processed to assist in determining if the consumer has slowed or stopped, tending to indicate that the consumer is evaluating one or more items for purchase. The accelerometer 60 can be a sensor that is operable to detect the motion of the consumer wearing the head mountable unit 14. The accelerometer 60 can generate a signal based on the movement that is detected and communicate the signal to the processor 40. The motion that is detected can be the acceleration of the consumer and the processor 40 can derive the velocity of the consumer from the acceleration. Alternatively, the commerce server 12 can process the acceleration signal to derive the velocity and acceleration of the consumer in the retail store.
The proximity sensor 62 can be operable to detect the presence of nearby objects without any physical contact. The proximity sensor 62 can apply an electromagnetic field or a beam of electromagnetic radiation such infrared and assess changes in the field or in the return signal. Alternatively, the proximity sensor 62 can apply capacitive photoelectric principles or induction. The proximity sensor 62 can generate a proximity signal and communicate the proximity signal to the processor 40. The proximity sensor 62 can be useful in determining when a consumer has grasped and is inspecting an item.
The distance sensor 64 can be operable to detect a distance between an object and the head mountable unit 14. The distance sensor 64 can generate a distance signal and communicate the signal to the processor 40. The distance sensor 64 can apply a laser to determine distance. The direction of the laser can be aligned with the direction that the consumer is facing. The distance signal can be useful in determining the distance to an object in the video signal generated by one of the cameras 42, which can be useful in determining the consumer's location in the retail store.
FIG. 3 is a block diagram illustrating a commerce server 212 according to some embodiments of the present disclosure. In the illustrated embodiment, the commerce server 212 can include an item database 214, and a shopping list database 216. The commerce server 212 can also include a processing device 218 configured to include a receiving module 220, an item selection module 222, a transmission module 224, a determination module 226, a modification module 228, and an audio processing module 230. The determination module 226 can include a video processing sub-module 232, an orientation sub-module 234, and a position sub-module 236.
Any combination of one or more computer-usable or computer-readable media may be utilized in various embodiments of the disclosure. For example, a computer-readable medium may include one or more of a portable computer diskette, a hard disk, a random access memory (RAM) device, a read-only memory (ROM) device, an erasable programmable read-only memory (EPROM or Flash memory) device, a portable compact disc read-only memory (CDROM), an optical storage device, and a magnetic storage device. Computer program code for carrying out operations of the present disclosure may be written in any combination of one or more programming languages.
The item database 214 can include in memory the identities of a plurality of items. The plurality of items can be the items offered for sale in a retail store associated with the commerce server 212. The item database 214 can also contain a floor plan of the retail store, including the location of each of the plurality of items within the retail store. The item database 214 can also contain image data for each of the items offered for sale in the retail store. The data in the item database 214 can be organized based on one or more tables that may utilize one or more algorithms and/or indexes.
The shopping list database 216 can include memory containing one or more shopping lists generated by consumers. Each of the shopping lists includes a plurality of items offered for sale in the retail store. Each of the plurality of shopping lists can be correlated to a particular consumer. The data in the shopping list database 216 can be organized based on one or more tables that may utilize one or more algorithms and/or indexes.
The processing device 218 can communicate with the databases 214, 216 and receive one or more signals from the head mountable unit 14. The processing device 218 can include computer readable memory storing computer readable instructions and one or more processors executing the computer readable instructions.
The receiving module 220 can be configured to receive one or more shopping list signals from primary consumer. The receiving module 220 can be operable to receive signals over the network 20 and then communicate the data contained in the signals to other components of the commerce server 212. For example, the receiving module 220 can direct the data contained in shopping list signals that are received from a consumer to the shopping list database 216 to establish a shopping list for a particular consumer.
The item selection module 222 can access shopping lists stored in the shopping list database 216 and can be configured to select an item from the shopping list of a consumer. The item selection module 222 can also access the item database 214 to correlate items on the shopping list with the locations of these items in the retail store. The selected item can be transmitted to the consumer as a reminder of the current item to pursue as the consumer shops.
The item selection module 222 can be configured to select items in the order that the items were added to the shopping list. Alternatively, the item selection module 222 can be configured to select items in an order that minimizes the distance a consumer must travel to acquire all of the items on the shopping list.
The transmission module 224 can be configured to transmit an item signal to the consumer over the network 20. The item signal corresponds to the item from the shopping list selected by the item selection module 222. The transmission module 224 and the item selection module 222 can thus function cooperatively. The item signal can be received by the head mountable unit 14 and result in the item being displayed on the display 46. A visual message resulting from the item signal can be continuously displayed until the item is acquired. Alternatively, the visual message resulting from the item signal can be displayed intermittently as the consumer travels to the location of the item in the retail store.
The determination module 226 can receive one or more signals from the augmented reality device and, in response, determine when an item from the shopping list has been placed in a shopping container, such as a shopping cart or basket. In some embodiments of the present disclosure, the video processing sub-module 232 of the determination module 226 can be configured to receive a video signal from the augmented reality device. The camera 42 can generate a video signal that is transmitted to the commerce server 212. The display 46 of the head mountable unit 14 can overlap the field of view of the camera 42. Thus, the view of the consumer through the display 46 can also define the video signal generated by the camera 42 and communicated to the commerce server 212.
The video processing sub-module 232 can implement known video recognition/analysis techniques and algorithms to analyze the video signal received from the augmented reality device to identify images or portions of images indicative of the placement of an item in a shopping container. For example, the video processing sub-module 232 can identify the consumer's hand positioned within a perimeter of the shopping container. In some embodiments of the present disclosure, indicia can be positioned along at least a portion of a perimeter of the shopping container. Indicia can be positioned along two opposite portions of the perimeter of the shopping container. An image of the consumer's hand disposed between the indicia positioned along the two opposite portions of the perimeter can be indicative of an item being placed in the shopping container. Some embodiments of the present disclosure can be practiced with indicia on more than two portions of the perimeter of the shopping container or without indicia on the perimeter of the shopping container.
The video processing sub-module 232 can also be configured to identify the item placed in the shopping container based on the image data of the item. The video data showing an item being placed in a shopping container can be further analyzed to determine the identity of the item. The video processing sub-module 232 can access the item database 214 and compare image data in the video signal with image data associated with items offered for sale in the retail store. The comparison of the image in the video signal with images in the item database 214 can be limited to only items on the shopping list in some embodiments of the present disclosure.
The orientation sub-module 234 of the determination module 226 can receive the orientation signal from the orientation sensor 58 of the head mountable unit 14. The orientation signal can be generated by the orientation sensor 58 and contain data corresponding to an orientation of the consumer's head. The consumer's head can be oriented downward, upwardly, or generally parallel with the ground. The orientation signal can be applied by the determination module 226 to complement that analysis of the video signal. For example, the orientation sub-module 234 can confirm that the orientation signal indicates that the consumer's head is oriented downwardly when the image of the item being placed in the shopping container is captured.
In some embodiments, the processing device 218 can also include a position module 236. The position module 236 can receive the position signal from the head mountable unit 14. The position signal can be generated by the position sensor 56 and contain data corresponding to a location of the head mountable unit 14 in the retail store. It is noted that the position could be determined in other ways in other embodiments of the present disclosure. The position signal can be applied by the determination module 226 to complement that analysis of the video signal. The item identified by the video processing sub-module 232 can be assessed by the determination module 226 in view of the position of the head mountable unit 14 within the retail store. For example, the determination module 226 can confirm that the item identified by the video processing sub-module 232 is located within the retail store generally proximate to the position of the head mountable unit 14 when the image of the item being placed in the shopping container is captured. Generally, a functional combination of inputs from the gyroscope, accelerometer, compass of the augmented reality device and a clock (not shown but possibly inherent in the commerce server 212 and/or the head mountable unit 14) can track the consumer movements between known landmarks identified by image recognition or other means.
The modification module 228 can be configured to modify a shopping list stored in the shopping list database in response to the operation of the determination module 226. For example, the modification module 228 can modify the shopping list by removing the item placed in the shopping container from the shopping list. The modification module 228 can also function cooperatively with the item selection module 222. For example, the modification module 228 can direct the item selection module 222 to select another item signal to transmit to the head mountable unit when the item associated with the current item signal has been placed in the shopping container.
In some embodiments of the present disclosure, the commerce server 212 can perform a process to confirm that the item determined to have been placed in the shopping container was in fact placed in the shopping container. The modification module 228 can be configured to execute the confirmation function. The modification module 228 can direct the transmission module 224 to transmit a confirmation query to the head mountable unit 14. For example, the confirmation query can be textual and appear on the display 46 or be audible and can be played on the speaker 52.
The consumer can audibly respond to the confirmation query in some embodiments of the present disclosure. The consumer's speech can be captured by the microphone 44 and transmitted to the commerce server 212. The processing device 218 can include an audio processing module 230 to analyze the signal containing the consumer's response to confirmation query. The audio processing module 230 can implement known speech recognition techniques to identify speech in an audio signal, such as a voice message indicating that commerce server has correctly determined that a particular item has been placed in a shopping container.
If the determination module 226 has not correctly determined the identity of the item placed in the shopping container, pursuant to the consumer's response to the confirmation query, the modification module 228 can direct the determination module 226 to repeat the analysis of the video signal and determine another item identity. The modification module 228 can also be configured to prompt the consumer to speak the identity of the item placed in the shopping container in some embodiments of the present disclosure. The audio processing module 230 can implement known speech recognition techniques to identify speech in an audio signal, such as a voice message indicating the identity of the item placed in the shopping container. The modification module 228 can remove the item identified by the audio processing module 230 from the shopping list. A confirmation process is optional to embodiments of the present disclosure.
As set forth above, the modification module 228 can also direct the item selection module 222 to select the next item on the shopping list for transmission to the consumer. The transmission module 224 can change from transmitting the first or current item signal to transmitting a second item signal different from the first item signal in response to the determination that the current item has been placed in the shopping container.
It is noted that the various processing functions set forth above can be executed differently than described above in order to enhance the efficiency of an embodiment of the present disclosure in a particular operating environment. The processor 40 can assume a greater role in processing some of the signals in some embodiments of the present disclosure. For example, in some embodiments, the processor 40 on the head mountable unit 14 could modify the video stream to require less bandwidth. The processor 40 could convert a video signal containing color to black and white in order to reduce the bandwidth required for transmitting the video signal. In some embodiments, the processor 40 could crop the video, or sample the video and display frames of interest. A frame of interest could be a frame that is significantly different from other frames, such as a generally low quality video having an occasional high quality frame. Thus, in some embodiments, the processor 40 could selectively extract video or data of interest from a video signal containing data of interest and other data. Further, the processor 40 could process audio signals received through the microphone 44, such signals corresponding to audible commands from the consumer.
