These teachings relate generally to shopping environments and more particularly to devices, systems and methods for assisting customers and/or workers in those shopping environments.
In a modern retail store environment, there is a need to improve the customer experience and/or convenience for the customer. Whether shopping in a large format (big box) store or smaller format (neighborhood) store, customers often require assistance that employees of the store are not always able to provide. For example, particularly during peak hours, there may not be enough employees available to assist customers such that customer questions go unanswered. Additionally, due to high employee turnover rates, available employees may not be fully trained or have access to information to adequately support customers. Other routine tasks also are difficult to keep up with, particularly during peak hours. For example, shopping carts are left abandoned, aisles become messy, inventory is not displayed in the proper locations or is not even placed on the sales floor, shelf prices may not be properly set, and theft is hard to discourage. All of these issues can result in low customer satisfaction or reduced convenience to the customer. With increasing competition from non-traditional shopping mechanisms, such as online shopping provided by e-commerce merchants and alternative store formats, it can be important for “brick and mortar” retailers to focus on improving the overall customer experience and/or convenience.
The above needs are at least partially met through provision of embodiments of systems, devices, and methods designed to provide assistance to customers and/or workers in a shopping facility, such as described in the following detailed description, particularly when studied in conjunction with the drawings, wherein:
Elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions and/or relative positioning of some of the elements in the figures may be exaggerated relative to other elements to help to improve understanding of various embodiments of the present teachings. Also, common but well-understood elements that are useful or necessary in a commercially feasible embodiment are often not depicted in order to facilitate a less obstructed view of these various embodiments of the present teachings. Certain actions and/or steps may be described or depicted in a particular order of occurrence while those skilled in the art will understand that such specificity with respect to sequence is not actually required. The terms and expressions used herein have the ordinary technical meaning as is accorded to such terms and expressions by persons skilled in the technical field as set forth above except where different specific meanings have otherwise been set forth herein.
The following description is not to be taken in a limiting sense, but is made merely for the purpose of describing the general principles of exemplary embodiments. Reference throughout this specification to “one embodiment,” “an embodiment,” or similar language means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases “in one embodiment,” “in an embodiment,” and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment.
Generally speaking, pursuant to various embodiments, systems, devices and methods are provided for assistance of persons at a shopping facility. Generally, assistance may be provided to customers or shoppers at the facility and/or to workers at the facility. The facility may be any type of shopping facility at a location in which products for display and/or for sale are variously distributed throughout the shopping facility space. The shopping facility may be a retail sales facility, or any other type of facility in which products are displayed and/or sold. The shopping facility may include one or more of sales floor areas, checkout locations (i.e., point of sale (POS) locations), customer service areas other than checkout locations (such as service areas to handle returns), parking locations, entrance and exit areas, stock room areas, stock receiving areas, hallway areas, common areas shared by merchants, and so on. Generally, a shopping facility includes areas that may be dynamic in terms of the physical structures occupying the space or area and objects, items, machinery and/or persons moving in the area. For example, the sales floor area may include product storage units, shelves, racks, modules, bins, etc., and other walls, dividers, partitions, etc. that may be configured in different layouts or physical arrangements. In other example, persons or other movable objects may be freely and independently traveling through the shopping facility space. And in another example, the persons or movable objects move according to known travel patterns and timing. The facility may be any size of format facility, and may include products from one or more merchants. For example, a facility may be a single store operated by one merchant or may be a collection of stores covering multiple merchants such as a mall. Generally, the system makes use of automated, robotic mobile devices, e.g., motorized transport units, that are capable of self-powered movement through a space of the shopping facility and providing any number of functions. Movement and operation of such devices may be controlled by a central computer system or may be autonomously controlled by the motorized transport units themselves. Various embodiments provide one or more user interfaces to allow various users to interact with the system including the automated mobile devices and/or to directly interact with the automated mobile devices. In some embodiments, the automated mobile devices and the corresponding system serve to enhance a customer shopping experience in the shopping facility, e.g., by assisting shoppers and/or workers at the facility.
In some embodiments, a shopping facility personal assistance system comprises: a plurality of motorized transport units located in and configured to move through a shopping facility space; a plurality of user interface units, each corresponding to a respective motorized transport unit during use of the respective motorized transport unit; and a central computer system having a network interface such that the central computer system wirelessly communicates with one or both of the plurality of motorized transport units and the plurality of user interface units, wherein the central computer system is configured to control movement of the plurality of motorized transport units through the shopping facility space based at least on inputs from the plurality of user interface units.
System Overview
Referring now to the drawings,
In the example of
These motorized transport units 102 are located in the shopping facility 101 and are configured to move throughout the shopping facility space. Further details regarding such motorized transport units 102 appear further below. Generally speaking, these motorized transport units 102 are configured to either comprise, or to selectively couple to, a corresponding movable item container 104. A simple example of an item container 104 would be a shopping cart as one typically finds at many retail facilities, or a rocket cart, a flatbed cart or any other mobile basket or platform that may be used to gather items for potential purchase.
In some embodiments, these motorized transport units 102 wirelessly communicate with, and are wholly or largely controlled by, the central computer system 106. In particular, in some embodiments, the central computer system 106 is configured to control movement of the motorized transport units 102 through the shopping facility space based on a variety of inputs. For example, the central computer system 106 communicates with each motorized transport unit 102 via the wireless network 124 which may be one or more wireless networks of one or more wireless network types (such as, a wireless local area network, a wireless personal area network, a wireless mesh network, a wireless star network, a wireless wide area network, a cellular network, and so on), capable of providing wireless coverage of the desired range of the motorized transport units 102 according to any known wireless protocols, including but not limited to a cellular, Wi-Fi, Zigbee or Bluetooth network.
By one approach the central computer system 106 is a computer based device and includes at least one control circuit 108, at least one memory 110 and at least one wired and/or wireless network interface 112. Such a control circuit 108 can comprise a fixed-purpose hard-wired platform or can comprise a partially or wholly programmable platform, such as a microcontroller, an application specification integrated circuit, a field programmable gate array, and so on. These architectural options are well known and understood in the art and require no further description here. This control circuit 108 is configured (for example, by using corresponding programming stored in the memory 110 as will be well understood by those skilled in the art) to carry out one or more of the steps, actions, and/or functions described herein.
In this illustrative example the control circuit 108 operably couples to one or more memories 110. The memory 110 may be integral to the control circuit 108 or can be physically discrete (in whole or in part) from the control circuit 108 as desired. This memory 110 can also be local with respect to the control circuit 108 (where, for example, both share a common circuit board, chassis, power supply, and/or housing) or can be partially or wholly remote with respect to the control circuit 108 (where, for example, the memory 110 is physically located in another facility, metropolitan area, or even country as compared to the control circuit 108).
This memory 110 can serve, for example, to non-transitorily store the computer instructions that, when executed by the control circuit 108, cause the control circuit 108 to behave as described herein. (As used herein, this reference to “non-transitorily” will be understood to refer to a non-ephemeral state for the stored contents (and hence excludes when the stored contents merely constitute signals or waves) rather than volatility of the storage media itself and hence includes both non-volatile memory (such as read-only memory (ROM) as well as volatile memory (such as an erasable programmable read-only memory (EPROM).)
Additionally, at least one database 126 may be accessible by the central computer system 106. Such databases may be integrated into the central computer system 106 or separate from it. Such databases may be at the location of the shopping facility 101 or remote from the shopping facility 101. Regardless of location, the databases comprise memory to store and organize certain data for use by the central control system 106. In some embodiments, the at least one database 126 may store data pertaining to one or more of: shopping facility mapping data, customer data, customer shopping data and patterns, inventory data, product pricing data, and so on.
In this illustrative example, the central computer system 106 also wirelessly communicates with a plurality of user interface units 114. These teachings will accommodate a variety of user interface units including, but not limited to, mobile and/or handheld electronic devices such as so-called smart phones and portable computers such as tablet/pad-styled computers. Generally speaking, these user interface units 114 should be able to wirelessly communicate with the central computer system 106 via a wireless network, such as the wireless network 124 of the shopping facility 101 (such as a Wi-Fi wireless network). These user interface units 114 generally provide a user interface for interaction with the system. In some embodiments, a given motorized transport unit 102 is paired with, associated with, assigned to or otherwise made to correspond with a given user interface unit 114. In some embodiments, these user interface units 114 should also be able to receive verbally-expressed input from a user and forward that content to the central computer system 106 or a motorized transport unit 102 and/or convert that verbally-expressed input into a form useful to the central computer system 106 or a motorized transport unit 102.
By one approach at least some of the user interface units 114 belong to corresponding customers who have come to the shopping facility 101 to shop. By another approach, in lieu of the foregoing or in combination therewith, at least some of the user interface units 114 belong to the shopping facility 101 and are loaned to individual customers to employ as described herein. In some embodiments, one or more user interface units 114 are attachable to a given movable item container 104 or are integrated with the movable item container 104. Similarly, in some embodiments, one or more user interface units 114 may be those of shopping facility workers, belong to the shopping facility 101 and are loaned to the workers, or a combination thereof.
In some embodiments, the user interface units 114 may be general purpose computer devices that include computer programming code to allow it to interact with the system 106. For example, such programming may be in the form of an application installed on the user interface unit 114 or in the form of a browser that displays a user interface provided by the central computer system 106 or other remote computer or server (such as a web server). In some embodiments, one or more user interface units 114 may be special purpose devices that are programmed to primarily function as a user interface for the system 100. Depending on the functionality and use case, user interface units 114 may be operated by customers of the shopping facility or may be operated by workers at the shopping facility, such as facility employees (associates or colleagues), vendors, suppliers, contractors, etc.
By one approach, the system 100 optionally includes one or more video cameras 118. Captured video imagery from such a video camera 118 can be provided to the central computer system 106. That information can then serve, for example, to help the central computer system 106 determine a present location of one or more of the motorized transport units 102 and/or determine issues or concerns regarding automated movement of those motorized transport units 102 in the shopping facility space. As one simple example in these regards, such video information can permit the central computer system 106, at least in part, to detect an object in a path of movement of a particular one of the motorized transport units 102.
By one approach these video cameras 118 comprise existing surveillance equipment employed at the shopping facility 101 to serve, for example, various security purposes. By another approach these video cameras 118 are dedicated to providing video content to the central computer system 106 to facilitate the latter's control of the motorized transport units 102. If desired, the video cameras 118 can have a selectively movable field of view and/or zoom capability that the central computer system 106 controls as appropriate to help ensure receipt of useful information at any given moment.
In some embodiments, a location detection system 116 is provided at the shopping facility 101. The location detection system 116 provides input to the central computer system 106 useful to help determine the location of one or more of the motorized transport units 102. In some embodiments, the location detection system 116 includes a series of light sources (e.g., LEDs (light-emitting diodes)) that are mounted in the ceiling at known positions throughout the space and that each encode data in the emitted light that identifies the source of the light (and thus, the location of the light). As a given motorized transport unit 102 moves through the space, light sensors (or light receivers) at the motorized transport unit 102, on the movable item container 104 and/or at the user interface unit 114 receive the light and can decode the data. This data is sent back to the central computer system 106 which can determine the position of the motorized transport unit 102 by the data of the light it receives, since it can relate the light data to a mapping of the light sources to locations at the facility 101. Generally, such lighting systems are known and commercially available, e.g., the ByteLight system from ByteLight of Boston, Mass. In embodiments using a ByteLight system, a typical display screen of the typical smart phone device can be used as a light sensor or light receiver to receive and process data encoded into the light from the ByteLight light sources.
In other embodiments, the location detection system 116 includes a series of low energy radio beacons (e.g., Bluetooth low energy beacons) at known positions throughout the space and that each encode data in the emitted radio signal that identifies the beacon (and thus, the location of the beacon). As a given motorized transport unit 102 moves through the space, low energy receivers at the motorized transport unit 102, on the movable item container 104 and/or at the user interface unit 114 receive the radio signal and can decode the data. This data is sent back to the central computer system 106 which can determine the position of the motorized transport unit 102 by the location encoded in the radio signal it receives, since it can relate the location data to a mapping of the low energy radio beacons to locations at the facility 101. Generally, such low energy radio systems are known and commercially available. In embodiments using a Bluetooth low energy radio system, a typical Bluetooth radio of a typical smart phone device can be used as a receiver to receive and process data encoded into the Bluetooth low energy radio signals from the Bluetooth low energy beacons.
In still other embodiments, the location detection system 116 includes a series of audio beacons at known positions throughout the space and that each encode data in the emitted audio signal that identifies the beacon (and thus, the location of the beacon). As a given motorized transport unit 102 moves through the space, microphones at the motorized transport unit 102, on the movable item container 104 and/or at the user interface unit 114 receive the audio signal and can decode the data. This data is sent back to the central computer system 106 which can determine the position of the motorized transport unit 102 by the location encoded in the audio signal it receives, since it can relate the location data to a mapping of the audio beacons to locations at the facility 101. Generally, such audio beacon systems are known and commercially available. In embodiments using an audio beacon system, a typical microphone of a typical smart phone device can be used as a receiver to receive and process data encoded into the audio signals from the audio beacon.
Also optionally, the central computer system 106 can operably couple to one or more user interface computers 128 (comprising, for example, a display and a user input interface such as a keyboard, touch screen, and/or cursor-movement device). Such a user interface computer 128 can permit, for example, a worker (e.g., an associate, analyst, etc.) at the retail or shopping facility 101 to monitor the operations of the central computer system 106 and/or to attend to any of a variety of administrative, configuration or evaluation tasks as may correspond to the programming and operation of the central computer system 106. Such user interface computers 128 may be at or remote from the location of the facility 101 and may access one or more the databases 126.
In some embodiments, the system 100 includes at least one motorized transport unit (MTU) storage unit or dispenser 120 at various locations in the shopping facility 101. The dispenser 120 provides for storage of motorized transport units 102 that are ready to be assigned to customers and/or workers. In some embodiments, the dispenser 120 takes the form of a cylinder within which motorized transports units 102 are stacked and released through the bottom of the dispenser 120. Further details of such embodiments are provided further below. In some embodiments, the dispenser 120 may be fixed in location or may be mobile and capable of transporting itself to a given location or utilizing a motorized transport unit 102 to transport the dispenser 120, then dispense one or more motorized transport units 102.
In some embodiments, the system 100 includes at least one motorized transport unit (MTU) docking station 122. These docking stations 122 provide locations where motorized transport units 102 can travel and connect to. For example, the motorized transport units 102 may be stored and charged at the docking station 122 for later use, and/or may be serviced at the docking station 122.
In accordance with some embodiments, a given motorized transport unit 102 detachably connects to a movable item container 104 and is configured to move the movable item container 104 through the shopping facility space under control of the central computer system 106 and/or the user interface unit 114. For example, a motorized transport unit 102 can move to a position underneath a movable item container 104 (such as a shopping cart, a rocket cart, a flatbed cart, or any other mobile basket or platform), align itself with the movable item container 104 (e.g., using sensors) and then raise itself to engage an undersurface of the movable item container 104 and lift a portion of the movable item container 104. Once the motorized transport unit is cooperating with the movable item container 104 (e.g., lifting a portion of the movable item container), the motorized transport unit 102 can continue to move throughout the facility space 101 taking the movable item container 104 with it. In some examples, the motorized transport unit 102 takes the form of the motorized transport unit 202 of
In addition to detachably coupling to movable item containers 104 (such as shopping carts), in some embodiments, motorized transport units 102 can move to and engage or connect to an item display module 130 and/or an item storage unit or locker 132. For example, an item display module 130 may take the form of a mobile display rack or shelving unit configured to house and display certain items for sale. It may be desired to position the display module 130 at various locations within the shopping facility 101 at various times. Thus, one or more motorized transport units 102 may move (as controlled by the central computer system 106) underneath the item display module 130, extend upward to lift the module 130 and then move it to the desired location. A storage locker 132 may be a storage device where items for purchase are collected and placed therein for a customer and/or worker to later retrieve. In some embodiments, one or more motorized transport units 102 may be used to move the storage locker to a desired location in the shopping facility 101. Similar to how a motorized transport unit engages a movable item container 104 or item display module 130, one or more motorized transport units 102 may move (as controlled by the central computer system 106) underneath the storage locker 132, extend upward to lift the locker 132 and then move it to the desired location.
The control circuit 406 operably couples to a motorized wheel system 410. This motorized wheel system 410 functions as a locomotion system to permit the motorized transport unit 102 to move within the aforementioned retail or shopping facility 101 (thus, the motorized wheel system 410 may more generically be referred to as a locomotion system). Generally speaking, this motorized wheel system 410 will include at least one drive wheel (i.e., a wheel that rotates (around a horizontal axis) under power to thereby cause the motorized transport unit 102 to move through interaction with, for example, the floor of the shopping facility 101). The motorized wheel system 410 can include any number of rotating wheels and/or other floor-contacting mechanisms as may be desired and/or appropriate to the application setting.
The motorized wheel system 410 also includes a steering mechanism of choice. One simple example in these regards comprises one or more of the aforementioned wheels that can swivel about a vertical axis to thereby cause the moving motorized transport unit 102 to turn as well.
Numerous examples of motorized wheel systems are known in the art. Accordingly, further elaboration in these regards is not provided here for the sake of brevity save to note that the aforementioned control circuit 406 is configured to control the various operating states of the motorized wheel system 410 to thereby control when and how the motorized wheel system 410 operates.
In this illustrative example, the control circuit 406 also operably couples to at least one wireless transceiver 412 that operates according to any known wireless protocol. This wireless transceiver 412 can comprise, for example, a Wi-Fi-compatible and/or Bluetooth-compatible transceiver that can communicate with the aforementioned central computer system 106 via the aforementioned wireless network 124 of the shopping facility 101. So configured the control circuit 406 of the motorized transport unit 102 can provide information to the central computer system 106 and can receive information and/or instructions from the central computer system 106. As one simple example in these regards, the control circuit 406 can receive instructions from the central computer system 106 regarding movement of the motorized transport unit 102.
These teachings will accommodate using any of a wide variety of wireless technologies as desired and/or as may be appropriate in a given application setting. These teachings will also accommodate employing two or more different wireless transceivers 412 if desired.
The control circuit 406 also couples to one or more on-board sensors 414. These teachings will accommodate a wide variety of sensor technologies and form factors. By one approach at least one such sensor 414 can comprise a light sensor or light receiver. When the aforementioned location detection system 116 comprises a plurality of light emitters disposed at particular locations within the shopping facility 101, such a light sensor can provide information that the control circuit 406 and/or the central computer system 106 employs to determine a present location and/or orientation of the motorized transport unit 102.
As another example, such a sensor 414 can comprise a distance measurement unit configured to detect a distance between the motorized transport unit 102 and one or more objects or surfaces around the motorized transport unit 102 (such as an object that lies in a projected path of movement for the motorized transport unit 102 through the shopping facility 101). These teachings will accommodate any of a variety of distance measurement units including optical units and sound/ultrasound units. In one example, a sensor 414 comprises a laser distance sensor device capable of determining a distance to objects in proximity to the sensor. In some embodiments, a sensor 414 comprises an optical based scanning device to sense and read optical patterns in proximity to the sensor, such as bar codes variously located on structures in the shopping facility 101. In some embodiments, a sensor 414 comprises a radio frequency identification (RFID) tag reader capable of reading RFID tags in proximity to the sensor. Such sensors may be useful to determine proximity to nearby objects, avoid collisions, orient the motorized transport unit at a proper alignment orientation to engage a movable item container, and so on.
The foregoing examples are intended to be illustrative and are not intended to convey an exhaustive listing of all possible sensors. Instead, it will be understood that these teachings will accommodate sensing any of a wide variety of circumstances or phenomena to support the operating functionality of the motorized transport unit 102 in a given application setting.
By one optional approach an audio input 416 (such as a microphone) and/or an audio output 418 (such as a speaker) can also operably couple to the control circuit 406. So configured the control circuit 406 can provide a variety of audible sounds to thereby communicate with a user of the motorized transport unit 102, other persons in the vicinity of the motorized transport unit 102, or even other motorized transport units 102 in the area. These audible sounds can include any of a variety of tones and other non-verbal sounds. These audible sounds can also include, in lieu of the foregoing or in combination therewith, pre-recorded or synthesized speech.
The audio input 416, in turn, provides a mechanism whereby, for example, a user provides verbal input to the control circuit 406. That verbal input can comprise, for example, instructions, inquiries, or information. So configured, a user can provide, for example, a question to the motorized transport unit 102 (such as, “Where are the towels?”). The control circuit 406 can cause that verbalized question to be transmitted to the central computer system 106 via the motorized transport unit's wireless transceiver 412. The central computer system 106 can process that verbal input to recognize the speech content and to then determine an appropriate response. That response might comprise, for example, transmitting back to the motorized transport unit 102 specific instructions regarding how to move the motorized transport unit 102 (via the aforementioned motorized wheel system 410) to the location in the shopping facility 101 where the towels are displayed.
In this example the motorized transport unit 102 includes a rechargeable power source 420 such as one or more batteries. The power provided by the rechargeable power source 420 can be made available to whichever components of the motorized transport unit 102 require electrical energy. By one approach the motorized transport unit 102 includes a plug or other electrically conductive interface that the control circuit 406 can utilize to automatically connect to an external source of electrical energy to thereby recharge the rechargeable power source 420.
By one approach the motorized transport unit 102 comprises an integral part of a movable item container 104 such as a grocery cart. As used herein, this reference to “integral” will be understood to refer to a non-temporary combination and joinder that is sufficiently complete so as to consider the combined elements to be as one. Such a joinder can be facilitated in a number of ways including by securing the motorized transport unit housing 402 to the item container using bolts or other threaded fasteners as versus, for example, a clip.
These teachings will also accommodate selectively and temporarily attaching the motorized transport unit 102 to an item container 104. In such a case the motorized transport unit 102 can include a movable item container coupling structure 422. By one approach this movable item container coupling structure 422 operably couples to a control circuit 202 to thereby permit the latter to control, for example, the latched and unlatched states of the movable item container coupling structure 422. So configured, by one approach the control circuit 406 can automatically and selectively move the motorized transport unit 102 (via the motorized wheel system 410) towards a particular item container until the movable item container coupling structure 422 can engage the item container to thereby temporarily physically couple the motorized transport unit 102 to the item container. So latched, the motorized transport unit 102 can then cause the item container to move with the motorized transport unit 102. In embodiments such as illustrated in
In either case, by combining the motorized transport unit 102 with an item container, and by controlling movement of the motorized transport unit 102 via the aforementioned central computer system 106, these teachings will facilitate a wide variety of useful ways to assist both customers and associates in a shopping facility setting. For example, the motorized transport unit 102 can be configured to follow a particular customer as they shop within the shopping facility 101. The customer can then place items they intend to purchase into the item container that is associated with the motorized transport unit 102.
In some embodiments, the motorized transport unit 102 includes an input/output (I/O) device 424 that is coupled to the control circuit 406. The I/O device 424 allows an external device to couple to the control unit 404. The function and purpose of connecting devices will depend on the application. In some examples, devices connecting to the I/O device 424 may add functionality to the control unit 404, allow the exporting of data from the control unit 404, allow the diagnosing of the motorized transport unit 102, and so on.
In some embodiments, the motorized transport unit 102 includes a user interface 426 including for example, user inputs and/or user outputs or displays depending on the intended interaction with the user. For example, user inputs could include any input device such as buttons, knobs, switches, touch sensitive surfaces or display screens, and so on. Example user outputs include lights, display screens, and so on. The user interface 426 may work together with or separate from any user interface implemented at a user interface unit 114 (such as a smart phone or tablet device).
The control unit 404 includes a memory 408 coupled to the control circuit 406 and that stores, for example, operating instructions and/or useful data. The control circuit 406 can comprise a fixed-purpose hard-wired platform or can comprise a partially or wholly programmable platform. These architectural options are well known and understood in the art and require no further description here. This control circuit 406 is configured (for example, by using corresponding programming stored in the memory 408 as will be well understood by those skilled in the art) to carry out one or more of the steps, actions, and/or functions described herein. The memory 408 may be integral to the control circuit 406 or can be physically discrete (in whole or in part) from the control circuit 406 as desired. This memory 408 can also be local with respect to the control circuit 406 (where, for example, both share a common circuit board, chassis, power supply, and/or housing) or can be partially or wholly remote with respect to the control circuit 406. This memory 408 can serve, for example, to non-transitorily store the computer instructions that, when executed by the control circuit 406, cause the control circuit 406 to behave as described herein. (As used herein, this reference to “non-transitorily” will be understood to refer to a non-ephemeral state for the stored contents (and hence excludes when the stored contents merely constitute signals or waves) rather than volatility of the storage media itself and hence includes both non-volatile memory (such as read-only memory (ROM) as well as volatile memory (such as an erasable programmable read-only memory (EPROM).)

Additional Features Overview
Referring generally to
Tagalong Steering: This feature allows a given motorized transport unit 102 to lead or follow a user (e.g., a customer and/or a worker) throughout the shopping facility 101. For example, the central computer system 106 uses the location detection system 116 to determine the location of the motorized transport unit 102. For example, LED smart lights (e.g., the ByteLight system) of the location detection system 116 transmit a location number to smart devices which are with the customer (e.g., user interface units 114), and/or on the item container 104/motorized transport unit 102. The central computer system 106 receives the LED location numbers received by the smart devices through the wireless network 124. Using this information, in some embodiments, the central computer system 106 uses a grid placed upon a 2D CAD map and 3D point cloud model (e.g., from the databases 126) to direct, track, and plot paths for the other devices. Using the grid, the motorized transport unit 102 can drive a movable item container 104 in a straight path rather than zigzagging around the facility. As the user moves from one grid to another, the motorized transport unit 102 drives the container 104 from one grid to the other. In some embodiments, as the user moves towards the motorized transport unit, it stays still until the customer moves beyond an adjoining grid.
Detecting Objects: In some embodiments, motorized transport units 102 detect objects through several sensors mounted on motorized transport unit 102, through independent cameras (e.g., video cameras 118), through sensors of a corresponding movable item container 104, and through communications with the central computer system 106. In some embodiments, with semi-autonomous capabilities, the motorized transport unit 102 will attempt to avoid obstacles, and if unable to avoid, it will notify the central computer system 106 of an exception condition. In some embodiments, using sensors 414 (such as distance measurement units, e.g., laser or other optical-based distance measurement sensors), the motorized transport unit 102 detects obstacles in its path, and will move to avoid, or stop until the obstacle is clear.
Visual Remote Steering: This feature enables movement and/or operation of a motorized transport unit 102 to be controlled by a user on-site, off-site, or anywhere in the world. This is due to the architecture of some embodiments where the central computer system 106 outputs the control signals to the motorized transport unit 102. These controls signals could have originated at any device in communication with the central computer system 106. For example, the movement signals sent to the motorized transport unit 102 may be movement instructions determined by the central computer system 106; commands received at a user interface unit 114 from a user; and commands received at the central computer system 106 from a remote user not located at the shopping facility space.
Determining Location: Similar to that described above, this feature enables the central computer system 106 to determine the location of devices in the shopping facility 101. For example, the central computer system 106 maps received LED light transmissions, Bluetooth low energy radio signals or audio signals (or other received signals encoded with location data) to a 2D map of the shopping facility. Objects within the area of the shopping facility are also mapped and associated with those transmissions. Using this information, the central computer system 106 can determine the location of devices such as motorized transport units.
Digital Physical Map Integration: In some embodiments, the system 100 is capable of integrating 2D and 3D maps of the shopping facility with physical locations of objects and workers. Once the central computer system 106 maps all objects to specific locations using algorithms, measurements and LED geo-location, for example, grids are applied which sections off the maps into access ways and blocked sections. Motorized transport units 102 use these grids for navigation and recognition. In some cases, grids are applied to 2D horizontal maps along with 3D models. In some cases, grids start at a higher unit level and then can be broken down into smaller units of measure by the central computer system 106 when needed to provide more accuracy.
Calling a Motorized Transport Unit: This feature provides multiple methods to request and schedule a motorized transport unit 102 for assistance in the shopping facility. In some embodiments, users can request use of a motorized transport unit 102 through the user interface unit 114. The central computer system 106 can check to see if there is an available motorized transport unit. Once assigned to a given user, other users will not be able to control the already assigned transport unit. Workers, such as store associates, may also reserve multiple motorized transport units in order to accomplish a coordinated large job.
Locker Delivery: In some embodiments, one or more motorized transport units 102 may be used to pick, pack, and deliver items to a particular storage locker 132. The motorized transport units 102 can couple to and move the storage locker to a desired location. In some embodiments, once delivered, the requestor will be notified that the items are ready to be picked up, and will be provided the locker location and locker security code key.
Route Optimization: In some embodiments, the central computer system automatically generates a travel route for one or more motorized transport units through the shopping facility space. In some embodiments, this route is based on one or more of a user provided list of items entered by the user via a user interface unit 114; user selected route preferences entered by the user via the user interface unit 114; user profile data received from a user information database (e.g., from one of databases 126); and product availability information from a retail inventory database (e.g., from one of databases 126). In some cases, the route intends to minimize the time it takes to get through the facility, and in some cases, may route the shopper to the least busy checkout area. Frequently, there will be multiple possible optimum routes. The route chosen may take the user by things the user is more likely to purchase (in case they forgot something), and away from things they are not likely to buy (to avoid embarrassment). That is, routing a customer through sporting goods, women's lingerie, baby food, or feminine products, who has never purchased such products based on past customer behavior would be non-productive, and potentially embarrassing to the customer. In some cases, a route may be determined from multiple possible routes based on past shopping behavior, e.g., if the customer typically buys a cold Diet Coke product, children's shoes or power tools, this information would be used to add weight to the best alternative routes, and determine the route accordingly.
Store Facing Features: In some embodiments, these features enable functions to support workers in performing store functions. For example, the system can assist workers to know what products and items are on the shelves and which ones need attention. For example, using 3D scanning and point cloud measurements, the central computer system can determine where products are supposed to be, enabling workers to be alerted to facing or zoning of issues along with potential inventory issues.
Phone Home: This feature allows users in a shopping facility 101 to be able to contact remote users who are not at the shopping facility 101 and include them in the shopping experience. For example, the user interface unit 114 may allow the user to place a voice call, a video call, or send a text message. With video call capabilities, a remote person can virtually accompany an in-store shopper, visually sharing the shopping experience while seeing and talking with the shopper. One or more remote shoppers may join the experience.
Returns: In some embodiments, the central computer system 106 can task a motorized transport unit 102 to keep the returns area clear of returned merchandise. For example, the transport unit may be instructed to move a cart from the returns area to a different department or area. Such commands may be initiated from video analytics (the central computer system analyzing camera footage showing a cart full), from an associate command (digital or verbal), or on a schedule, as other priority tasks allow. The motorized transport unit 102 can first bring an empty cart to the returns area, prior to removing a full one.
Bring a Container: One or more motorized transport units can retrieve a movable item container 104 (such as a shopping cart) to use. For example, upon a customer or worker request, the motorized transport unit 102 can re-position one or more item containers 104 from one location to another. In some cases, the system instructs the motorized transport unit where to obtain an empty item container for use. For example, the system can recognize an empty and idle item container that has been abandoned or instruct that one be retrieved from a cart storage area. In some cases, the call to retrieve an item container may be initiated through a call button placed throughout the facility, or through the interface of a user interface unit 114.
Respond to Voice Commands: In some cases, control of a given motorized transport unit is implemented through the acceptance of voice commands. For example, the user may speak voice commands to the motorized transport unit 102 itself and/or to the user interface unit 114. In some embodiments, a voice print is used to authorize to use of a motorized transport unit 102 to allow voice commands from single user at a time.
Retrieve Abandoned Item Containers: This feature allows the central computer system to track movement of movable item containers in and around the area of the shopping facility 101, including both the sale floor areas and the back-room areas. For example, using visual recognition through store cameras 118 or through user interface units 114, the central computer system 106 can identify abandoned and out-of-place movable item containers. In some cases, each movable item container has a transmitter or smart device which will send a unique identifier to facilitate tracking or other tasks and its position using LED geo-location identification. Using LED geo-location identification with the Determining Location feature through smart devices on each cart, the central computer system 106 can determine the length of time a movable item container 104 is stationary.
Stocker Assistance: This feature allows the central computer system to track movement of merchandise flow into and around the back-room areas. For example, using visual recognition and captured images, the central computer system 106 can determine if carts are loaded or not for moving merchandise between the back room areas and the sale floor areas. Tasks or alerts may be sent to workers to assign tasks.
Self-Docking: Motorized transport units 102 will run low or out of power when used. Before this happens, the motorized transport units 102 need to recharge to stay in service. According to this feature, motorized transport units 102 will self-dock and recharge (e.g., at a MTU docking station 122) to stay at maximum efficiency, when not in use. When use is completed, the motorized transport unit 102 will return to a docking station 122. In some cases, if the power is running low during use, a replacement motorized transport unit can be assigned to move into position and replace the motorized transport unit with low power. The transition from one unit to the next can be seamless to the user.
Item Container Retrieval: With this feature, the central computer system 106 can cause multiple motorized transport units 102 to retrieve abandoned item containers from exterior areas such as parking lots. For example, multiple motorized transport units are loaded into a movable dispenser, e.g., the motorized transport units are vertically stacked in the dispenser. The dispenser is moved to the exterior area and the transport units are dispensed. Based on video analytics, it is determined which item containers 104 are abandoned and for how long. A transport unit will attach to an abandoned cart and return it to a storage bay.
Motorized Transport Unit Dispenser: This feature provides the movable dispenser that contains and moves a group of motorized transport units to a given area (e.g., an exterior area such as a parking lot) to be dispensed for use. For example, motorized transport units can be moved to the parking lot to retrieve abandoned item containers 104. In some cases, the interior of the dispenser includes helically wound guide rails that mate with the guide member 208 to allow the motorized transport units to be guided to a position to be dispensed.
Specialized Module Retrieval: This feature allows the system 100 to track movement of merchandise flow into and around the sales floor areas and the back-room areas including special modules that may be needed to move to the sales floor. For example, using video analytics, the system can determine if a modular unit it loaded or empty. Such modular units may house items that are of seasonal or temporary use on the sales floor. For example, when it is raining, it is useful to move a module unit displaying umbrellas from a back room area (or a lesser accessed area of the sales floor) to a desired area of the sales floor area.
Authentication: This feature uses a voice imprint with an attention code/word to authenticate a user to a given motorized transport unit. One motorized transport unit can be swapped for another using this authentication. For example, a token is used during the session with the user. The token is a unique identifier for the session which is dropped once the session is ended. A logical token may be a session id used by the application of the user interface unit 114 to establish the session id when user logs on and when deciding to do use the system 100. In some embodiments, communications throughout the session are encrypted using SSL or other methods at transport level.
In accordance with some embodiments, further details are now provided for one or more of these and other features.
Various embodiments of systems and methods for providing route guidance to a customer in a retail space are now described. In a broad sense and in accordance with some embodiments, a system is described that provides route guidance to a customer in a shopping facility space and comprises a communication device configured to communicate with a user interface device, a store map database storing location information for a plurality of items available for purchase in the retail space, and a control circuit coupled to the communication device and the store map database. The control circuit is configured to receive a list of items for purchase from a user associated with the user interface device via the communication device, retrieve location information associated with each item of the list of items for purchase from the store map database, determine a route based on at least one user entered route preference and the location information associated with each item of the list of items for purchase, and provide the route to the user interface device.
In some embodiments, a customer may provide a merchant's or other shopping facility's computer system with a shopping list which the system will use to optimize a route through the store. In some embodiments, a motorized transport unit (MTU) (such as any of the MTUs 102, 202, 402 described herein) and/or a user interface unit (such as any of the user interface units 114) may lead the user and/or give directions along with a map showing current location and next product location. There may be an audible voice similar to a standard GPS navigation system guiding the customer down the different sections, rows and/or aisles of the store or shopping facility until the customer reach the item/product needed. When determining the optimized route, besides knowing the location of the customer or an MTU when provided with a shopping list, a final destination may also be taken into consideration by the system. For example, some customers prefer to perform checkout on the grocery side or the gardening section and the route may be determined accordingly. By way of further example, the customer's propensity to use the self-checkout counters or frequent the tobacco register may also be considered.
A shopping list may include one or more items. A Customer will be able to choose whether the MTU acts as an escort or provides a customer with the most expeditious route verbally or graphically. One of the most common questions customers ask store associates is where to find an item. The MTU 102 or a user interface device 114 may be configured to understand verbal queries and provide directions. For example, a customer may ask “where can I find shampoos?” and the user interface unit 114 will indicate the location of the shampoo section and provide a best path. If a customer says “show me” or “take me,” the MTU 102 may act as escort and lead or follow the customer to the requested item.
In some embodiments, the MTU 102 and/or the user interface unit 114 may notify a customer when specific items on the list are out of stock, saving travel to potentially unnecessary destinations. MTU and/or the user interface unit will provide alternate suggestions such as ordering the item on-line.
In some embodiments, the shopping list may contain distinct items, such as those identified by a merchant specific item number, Universal Product Code (UPC), Global Trade Identification Number (GTIN) or other means, general item identification, or a product category. Voice recognition and speech synthesis may also be used to input a shopping list into the merchant system. The system may also be configured to resolve the closest location that matches the data given.
The list may be sent to the MTU electronically (e.g., from the user interface device 114 or from the central computer system 106) in order for the unit to work autonomously. The MTU may return the collected items to the customer service area, for the “pick up today” program, or placed the item in a locker to be collected by the customer at a later time. The MTU's route may be optimized to minimize the time required to complete his task.
As an example, if the user added “Shampoo” to her shopping list, the system may be able to resolve the entry to a category and map that category to the aisle or aisles in which the category of items are carried. If the user provides more detail, the system may be able to return more precise location information back to the user. If the user entered “Pantene Pro-V Shampoo”, the system may be able to resolve that to a 4 foot (1.22 meter) wide section within an aisle. If the user enters item number 551733244, the system would be able to determine that the number corresponds to Pantene Pro-V Repair & Protect Miracle Repairing Shampoo, 21.1 fl oz, and provide the selling slot within the 4-foot wide section and aisle.
Further, the system may be configured to present the user with recommended products for generic product categories based on the customer's previous purchase history, propensity for trying new products, brand or product loyalty, and other factors.
As items are added to the list, the system may update the route through the store. In addition, the customer or user may allow the system to make additional recommendations for products that may be of interest. If the user adds those items or categories to the list, the system will further optimize the route to pass by the newly added products. The system may also be configured to notify the customer of any coupons or markdowns around user's current location.
In some embodiments, the route guidance system determines a route that minimizes the time it takes to get through the store. The system may further determine which register is least busy, or which cashier lane is quicker to checkout in choosing the final destination. Upon the customer's final approach to the checkout area, the system may analyze the best register for speedy checkout.
In some embodiments, the system may determine multiple possible optimum routes. The route chosen may take the customer by things they are more likely to buy (in case they forgot something), and away from things they are not likely to buy (to avoid embarrassment). For example, routing a customer through sporting goods, women's lingerie, baby food, or feminine products, who has never purchased these products would be non-productive, and potentially embarrassing to the customer. The system may be configured to avoid these areas based on past customer behavior. The reverse would also apply. For example, if the customer typically buys a cold diet soda, children's shoes, or power tools, this information would be used to add weight to the best alternative routes, and determine the route accordingly.
The route computer 620 includes a control circuit 621 and a memory 622, and may be generally referred to as a processor-based device. In some embodiments, the route guidance system 600 may be implemented to include with one or more of the central computer system 106, the user interface unit 114, and/or the computer device 500 described above. For example, the route computer 620 may be implemented as a software module of the central computer system 106. In some embodiments, the route guidance system 600 may be a separate standalone system from the system discussed above and provide route guidance in a system without MTUs such as described herein. The route computer 620 has stored on its memory 622, a set of computer readable instructions that is executable by the control circuit 621 to cause the control circuit 621 to provide route guidance to a customer in a shopping facility space based on a list of items provided by a user interface device 641 and user route references. In some embodiments, the route computer 620 may be located inside of and serve a specific shopping facility space operated by one or more merchants. In some embodiments, the route computer 620 may be at least partially implemented on a remote or cloud-based server that provides route guidance to one or more shopping facility spaces. A more detailed description of route guidance functionalities of the route computer 620 is provided herein with reference to
The route computer 620 is communicatively coupled to the store map database 610. The store map database 610 has stored within its memory, location information for a plurality of items available for purchase in a shopping facility space. The store map database 610 may also store or merchant location information corresponding to departments, product categories, product types, etc. The in-store location information may include one or more of, a 3-dimensional coordinate, a 2-dimensional coordinate, an aisle number, a row number, a display fixture identifier, a display container identifier, shelf height, and the like. In some embodiments, store map database 610 stores a planogram of the shopping space. A planogram of a shopping facility space generally refers a representation of the layout of the store and the placement of products and/or services within the store. In some embodiments, the store map database 610 also stores location information of other store features such as checkout counters, self-service counters, customer service counters, exits, in-store bank counters, ATMs, movie rental kiosks, vending machines, recycling kiosks, pharmacy, and the like. The system would then add these locations/features into the determined route. In some embodiments, the store map database 610 further stores retail related information such as inventory status of items, in store events, promotions, etc. The store map database 610 may be implemented with the memory 622 of the route computer 620 and/or another memory devices described in
The route computer 620 is further communicatively coupled to a communication device 630. The communication device 630 may be one or more of a network adapter, a radio transceiver, a wireless transceiver, and the like. Generally, the communication device 630 is configured to transmit data between the route computer 6120 and the user interface devices 641 via a communication channel such as the Internet, a local area network, a direct wireless communication, a secure private network, and the like.
Each user interface device 641 may be one or more of a portable user device such as the user interface unit 114 in
A user may be associated with one or more user interface devices. In some embodiments, user preferences and/or list of items for purchase are received from a first user interface device 641 and the route guidance is provided to another user interface device 641. For example, the user may enter a list of items for purchase and/or user preferences at home on a personal computer. When the user arrives at the store, route guidance may be provided to the user on his/her portable user device such that the user can follow the visual route guidance displayed on the portable user device. In another example, a list of items for purchase and/or user preferences may be entered with a portable user device having a display screen and the route guidance information may be provided to an MTU which physically guides the user through the store by leading or following the user according to the received route guidance information. In some embodiments, route guidance information may be provided to one or more of a portable user device and a motorized transport unit. An example of a route guidance that is provided via a portable user device and an MTU is described with reference to
While the store map database 610, the route computer 620, and the communication device 630 are shown as separate elements in
While only the store map database 610 in shown, the route computer 620 may be communicatively coupled to other sources of information used in determining a route for a user. For example, the system 600 may include a customer profile database. A customer profile may include one or more a customer demographic information, customer purchase history, customer route history, customer web browsing history, customer mobility information, and user entered preferences. User entered preferences may include preferences such as store areas to avoid, store areas to visit, store event to avoid, store event to visit, preference for the fastest route, preference for the shortest route, preference for child friendly route, preference for mobility friendly route, and the like. In some embodiments, the route computer is communicatively coupled to a location detection system 116 and/or a video camera 118 described with reference to
In step 710, a list of items for purchase is received at a control circuit. The list of items may include item types, item category, and/or specific items entered by a user. For example, the user may simply enter “shampoo” or enter “Pantene Pro-V Repair & Protect Miracle Repairing Shampoo.” A user may browse through items for purchase on a store website and/or in a store application and select items to purchase. The website or the store application may include a shopping list building graphical interface showing images of store departments, product categories, and specific items for the user to select. The shopping list building interface may also provide other functionalities such as keyword search and related item recommendation. The user may also issue voice commands to the user interface device or an MTU to modify the shopping list either prior to or during the shopping trip. The list of items for purchase may be generated and stored on a merchant server or may be uploaded to a merchant server when the user begins his/her shopping trip. The list of items for purchase may include any goods and services offered for sale in a shopping facility space. In some embodiments, the user may also select other store features to visit in step 710, for example, the user may select to stop by the pharmacy, the deli, the vending machine area, the movie rental kiosk, etc. during the shopping trip.
In step 720, the control circuit retrieves location information associated with each item on the list of items for purchase from a store map database. The location information may correspond to a category of items and/or a specific item. The location information of each item or category may include one or more of, 3-dimensional coordinate, 2-dimensional coordinate, aisle number, department identifier, section identifier, display fixture identifier, display container identifier, shelf height, and the like. In some embodiments, the location information is determined based a planogram of the shopping facility space. In some embodiments, other characteristics information corresponding items may also be stored in the store map database. For example, some of the items may be tagged as being bulky, heavy, refrigerated, frozen, heated, low in stock, age restricted, female specific, on sale, etc. This characteristics information may be used in the route determination in step 730.
In some embodiments, between steps 710 and 730, the system may determine if all items on the list of items for purchase are in stock. In the event that one or more items are not in stock, the location corresponding the out of stock item may be omitted in the route determined in step 730. In some embodiments, the portable user interface device may provide an indication that the item is out of stock and provide substitute item recommendations and/or other methods of purchasing the item such as purchasing at a nearby store or purchase online.
In some embodiments, between step 710 and 730, the control circuit also retrieves one or more of customer demographic information, customer purchase history, customer route history, customer web browsing history, customer mobility information, and a user entered preference from a profile associated with the user to be used in step 730. In some embodiments, the system also determines the customer's current location and a suitable end of route location for use in step 730. The end of route location may be determined based on one or more of user's parked car, user's preferred/selected checkout area, user's preferred/selected exit, etc.
In step 730, the system determines a route based on at least one user entered route preference and the location information associated with each item of the list of items for purchase. Generally, the system determines a route that passes by each item in the list of items for purchase and also conforms to the user's route preference/s. If an item is available at two or more locations, the system may select a location that minimizes the route length and/or best suits the user entered route preference/s. User entered route preferences may include many different factors. For example, a user can select a route type, store areas to avoid or to visit, store events to avoid or to visit, etc. The route may further be configured to include any other store features and user specific points of interests and/or restrictions. Types of information that are considered in determining the route in step 730 may be based on user specific route preference. Several examples of user route references that may be implemented with the disclosed system and method are described below.
In a first example, the user may select a fastest route preference. With this preference selected, a route may be optimized based on visiting all locations corresponding to each item on the list in the shortest amount of time. The fastest route determination may further take into account congested areas based upon real-time video analysis of store condition, historical traffic information corresponding to the time of day, and the like The system may also help the customer select a check-out lane based on cashier performance and/or current queue length determined based on video analysis. If other preferences are also entered, the fastest route meeting other preference may be determined.
In a second example, a user may select a shortest route preference. The shortest route is not always the fastest route depending on store layout and congestion condition. To determine the shortest route, the system may consider the current location of the customer, the location of the items for purchase, the location of the customer's car, and/or the location of the closest exit to the customer's car. The shortest route may be preferred over the fastest route for customers with mobility limitations. If other preferences are also entered, the shortest route meeting other preference may be determined.
In a third example, the user may select a discount items route preference. For example, the system may guide the customer through aisles with most items on sale, the clearance aisles, and areas with special discounts. The system may further be configured to guide the customers through areas with free samples, food tasting events, product demonstrations, etc. In some embodiments, in-store events are displayed to the user when route guidance is provided, and the user can select one or more events to he/she wishes to participate to modify the route.
In a fourth example, the user may select a treasure hunt route preference. In the treasure hunt mode, the system may suggest general areas for items on the shopping list and indicate (e.g., via the user interface device) if the customer is getting warmer or colder depending on the distance of the customer from specific items for purchase. The system may provide rewards to customers based on the time it took for the customer to find the items for purchase.
In a fifth example, the user may select a store tour route preference. A store layout or a list of departments may be displayed on the customer's portable device for the customer to select one or more areas they wish to visit. The selected area would then be included in the determined shopping route. As the shopper goes through the selected area, the portable user device may provide highlights and commentary of specific items and/or sections within the selected area.
In a sixth example, the user may select a long route preference in order to exercise during their shopping trip. With this preference, the system would still route the customer to each item on the list of items for purchase but would select a more roundabout route. In some embodiments, the system would determine a route such that the customer does not visit the same sections of the store repeatedly. In some embodiments, the user may enter a preferred trip length by either time or distance and a route meeting that length would be determined by the system.
In a seventh example, the user may enter a route preference that preserves item condition. If one or more items on the list of items for purchase are frozen (such as ice cream), heated, or need constant refrigeration, the route may be configured to pick up those items last. In some embodiments, the system may determine an acceptable time for the items to be outside of the controlled environment (for example, 15 minutes) and configure the route accordingly to avoid prolonged exposure to uncontrolled environment. In some embodiment, the system may keep track of the time that a frozen item has been removed from refrigeration and alert the customer if the time exceeds a threshold. The system may also be configured to similarly place heavy, bulky, or potentially embarrassing items towards the end of the route.
In an eighth example, the user may select to split the route by gender associated with the items for purchase. For example, products may be tagged as being associated with neutral, male, or female gender. The customer may place these three categories in order to configure the route. In some embodiments, the default configuration under this route preference is to stop by gender neutral items first, items matching the customer's gender second, and items associated with another gender last. For example, a male shopper may not wish to carry feminine hygiene products all around the store while he shops. With this option, he may be guided to pick up those products right before checkout.
In a ninth example, the user may select to split the route by age bracket associated with the items for purchase. Age brackets may be preset for groups such as babies, children, teens, young adults, age 40-55, 55+, etc. Similar to splitting route by gender, the user can configure how age brackets are ordered. The user may also adjust their own age bracket range and be provided a route accordingly.
In the tenth example, the user may select to split the route by department. Departments of a store (deli, produce, hardware, toys, etc.) may be presented on the portable user device for selection. The user may select the department by name, by checkboxes, or select an area in the store map, etc. The system would then determine a route that includes the selected department(s) even if the shopping list does not include an item in the selected department. Customer may similarly select other features of the store this way. For example, the customer can select to visit the restroom, the customer service counter, an in-store bank counter, an ATM, a movie rental kiosk, a lottery vending machine, a recycling kiosk, the pharmacy, and the like. The system would then add these locations/features into the determined route.
In the eleventh example, the user may select a favorite route preference. The favorite route may be based on the user's past route history and/or may be configurable by the user. The system may determine a route that includes all locations for items on the list of items for purchase that best approximate the user's favorite route.
The examples of user route preferences provided above are for illustration only. Other types of user preferences may also be implemented with the present system. Additionally, one or more preferences may be selected at the same time, and the system may base its route determination on each user configured route preference. For example, if the user selects to pass by areas with free samples, select to preserve food freshness, and select the shortest route reference. The system may determine a shortest route that still includes free sample areas while reducing the time any frozen item is out of refrigeration. In some embodiments, different types of preferences may be prioritized by either the user or the system. For example, a user may indicate which preference is the most important to him/her. In some embodiments, the system may alert the user if conflicting preferences are entered. The route references may be configured through a store website, a store application running on a portable user device, an in-store kiosk, and the like. The user may also be permitted to modify and store configured user route preferences any time.
The system may also take into consideration other information such as user shopping history and demographic information. User shopping history may include types of items and/or departments that the user most frequently purchases. The determined route may be configured to guide the user pass those departments/areas to increase the chance of additional purchase. Demographic information of the user may include user's age group, gender, ethnicity, family makeup, and the like. The system may determine items that are most likely to be purchased by the user based on his/her demographic information and determine a route that guides the user through areas more relevant to his/her demographic. In some embodiments, the system may also determine areas to avoid based on the user's demographic information. For example, the system may avoid guiding male shopper through the female intimates section of the store. In some embodiments, the system may also take into account the inventory level of items on the items for purchase list. For example, if an item is low in stock and there is a high likelihood of the item being sold out, the system may route the shopper to that item first, or may provide alternative suggestions for that item.
Each of the user preferences and considerations described above may be combined in various ways depending on the system's configuration and/or user configuration without departing from the spirit of the present disclosure. In some embodiments, user preferences may be stored in a user profile that is retrieved each time a route is determined for that user. In some embodiments, at least some of the user preferences may be entered just prior or during a shopping trip. In some embodiments, route preferences may be entered anytime during the shopping trip to modify the provided route.
In step 740, the route determined in step 730 is provided to a user interface device. In some embodiments, the user interface device may be an MTU which is configured to lead or guide an in-store shopper based on the determined route. In some embodiments, the user interface device may be a user interface unit 114 such as described herein. In some embodiments, the user interface device may be a portable user device having a display screen or a head mounted display. The route guidance can be provided to the user through one or more of voice, text, graphical, and physical guidance. Real-time turn-by-turn route guidance may be provided to the user according to a determined current user location. The current user location may be determined based on any known locating method, such as those described with reference to the location detection system 116 above. In some embodiments, the user device displays a store map including aisle, department information, and/or the user's current location. The store map may be a three-dimensional store map showing items displayed at different shelf heights. In some embodiments, when a user approaches a shelf having an item for purchase, an image of the shelf indicating the location of the item for purchase within the shelf may be displayed to the user to assist the user in locating the item. In some embodiments, the user interface device may alert the user through sound or image when the user approaches an item for purchase. Promotions such as applicable coupons, nearby markdown items, related items etc. may also be displayed alongside route guidance information or provided as an audio alert to the user.
In some embodiments, after step 730, the determined route may be updated and modified constantly. For example, if the user deviates from the determined route, the system may determine an updated route based on user's current location. In some embodiments, the system is configured to determine which items for purchase have already been picked up, and the updated route would only take the remaining items into consideration. In some embodiments, the user can modify route references and/or the list of item for purchase to cause the system to determine an updated route. For example, during the shopping trip, the customer may verbally instruct the user interface device to add an item to the shopping item, and a new route including the added item may be determined and provided to the user. In some embodiments, the user can select the route displayed on the portable user device to configure a new route. For example, the user may add or remove departments/items/events to visit using the displayed map and route.
In some embodiments, the route guidance ends when the system detects that the user has visited each location associated with items on the list of item for purchase and approached an end of route location such as a checkout counter, the exit, or customer's car in the parking lot.
In step 801, the central computer sets up a route guidance program. The central computer may be implemented with one or more of the route computer 620, the computer device 500, and the central computer system 106 described herein. In step 811, the customer opts into the program through a smart device such as the user interface unit 114, the computer device 500, and the user interface device 641 described herein. In step 812, the user selects routing preferences. Routing preferences may include one or more preferences described with reference to
In step 818, the customer approaches products on their shopping list. In step 806, the central computer detects that step 818 has occurred and alters the customer. In some embodiments, the central computer would cause the display on a portable user device to display a 3D map for indicating a 3-dimensional location of the desired product.
During steps 817, 821, and 822, the user may use a portable user device to reconfigure the shopping and/or routing preferences in steps 812 and 813. In some embodiments, the user may also switch between lead or follow at any time. Also during steps, 817, 821, and 822, the system may determine that the customer has deviated from the optimized route and alert the customer and/or generate a new optimized route based on the user's new position.
