Patent Application
20180139570
The present disclosure relates generally to an arrangement for, and a method of, associating an identifier (ID) of a handheld mobile device, such as a data capture device, with a location of the mobile device, and, more particularly, to detecting the location of the mobile device by recognition of a gesture, such as a hand wave, performed by a user of the mobile device.
Tracking systems are deployed in many diverse venues, such as retail stores, factories, warehouses, distribution centers, buildings, or like controlled indoor and outdoor areas, to track various users, such as employees or customers, who are holding or wearing, and operating, various types of mobile devices, such as portable data capture readers for capturing data from products in the venues, and/or portable electronic devices for executing computer applications, such as smartphones, tablets, computers, terminals, smartwatches, smart glasses, or the like. During such operation, it is desirable to associate an identifier (ID) of the mobile device, i.e., a string of numbers and/or letters that uniquely identifies the mobile device, with a location of the mobile device in the venue. For example, the association is important to link the captured data from the products with the location of the mobile device. As other examples, it is sometimes desirable to know where each employee is in the venue from the location of his or her mobile device, and it is also often desirable to send targeted information, such as product promotional information, to the mobile device of each customer for consideration by the customer during shopping at a retail venue.
One type of known tracking system is a video system that deploys cameras in the venue. The cameras typically use facial recognition to identify and track employees. However, the camera-based video system is not practical in many cases, because it has proven difficult to reliably distinguish between employees who may look alike and/or may be wearing similar uniforms. Another type of known tracking system is a radio frequency (RF) identification (RFID) system that deploys RFID tag readers in the venue. The RFID readers are operated, under the control of a network computer or host server that uses triangulation/trilateration techniques known in the art, to read an RFID tag on each mobile device to find its location. Still another type of known tracking system is an ultrasonic locationing system that deploys ultrasonic transmitters, e.g., speakers, in the venue. An ultrasonic receiver, e.g., a microphone, on each mobile device receives ultrasonic signals transmitted by the speakers to determine the location of each mobile device, again using triangulation/trilateration techniques known in the art. However, the known RFID and ultrasonic systems are not always reliable in their operation, and, in any event, their cost of manufacture, installation and operation may be prohibitive for some venues.
Accordingly, it would be desirable to reliably determine the location of each mobile device and, in turn, the location of the user of each mobile device without relying on such redundant systems as the aforementioned RFID and ultrasonic tracking systems; to reliably associate the device ID of each mobile device with the location of each mobile device; and to send targeted information, such as product promotional information, to the mobile device of each customer for consideration by the customer during shopping at a retail venue.
The accompanying figures, where like reference numerals refer to identical or functionally similar elements throughout the separate views, together with the detailed description below, are incorporated in and form part of the specification, and serve to further illustrate embodiments of concepts that include the claimed invention, and explain various principles and advantages of those embodiments.
Skilled artisans will appreciate that elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions and locations of some of the elements in the figures may be exaggerated relative to other elements to help to improve understanding of embodiments of the present invention.
The arrangement and method components have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present invention so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.
One aspect of this disclosure relates to a device association arrangement that includes one or more mobile devices, each movable and operable by one or more respective users in a venue. The venue can be any environment, such as a retail store, a factory, a warehouse, a distribution center, a building, or a like indoor or outdoor controlled area, preferably at which products are located. The mobile devices may be handheld data capture readers, such as radio frequency (RF) identification (RFID) tag readers for capturing data from RFID tags associated with the products in the venue, and/or near field communication (NFC) tag readers for capturing data from NFC tags associated with the products in the venue, and/or bar code symbol readers for capturing data from bar code symbols associated with the products in the venue, and/or image capture devices for capturing data by image capture from the products in the venue, and/or any electronic device for executing computer applications, such as smartphones, tablets, computers, terminals, smartwatches, smart glasses, or the like, that are held or worn, and operated, by human users, such as employees of the venue. Other human users may include customers who are carrying mobile devices, such as smartphones, during shopping at a retail venue.
Each mobile device is operative for transmitting a unique device identifier (ID) that identifies the respective mobile device. A camera system, preferably including one or more stationary cameras deployed in the venue, is operative for imaging each user in the venue. A control system, for example, a host server, is operatively connected to each mobile device and the camera system, and, in operation, prompts the user to perform a gesture, controls the camera system to image and detect the gesture and a location of the mobile device that is proximal to the detected gesture, receives the device ID from the mobile device, and associates the device ID with the location of the mobile device. The gesture is a visually prominent movement of a part of the user's body. For example, the gesture may be one or more waves of one of the user's hands, and/or one or more nods of the user's head. The control system may prompt the user to repeat the gesture if there is a lack of confidence in the location of the mobile device. For example, it could sometimes occur that two users may have crossed paths, and the control system may not reliably be able to distinguish between them. Also, sometimes one or more users may have temporarily left, and then returned to, the field of view of the camera, in which case, the control system may not reliably track each user without another gesture to update the control system.
The mobile device may transmit the device ID to the control system either before the control system prompts the user to perform the gesture, or after the camera system has detected the gesture. The control system sequences, and distinguishes among, all of the device IDs received from all the mobile devices. Advantageously, the control system sends a feedback indication to each user that the device ID has been associated with the location of the respective mobile device. The feedback indication may be a visual and/or audible alert at the mobile device.
Once the location of each mobile device is known and has been associated with the device ID, the location of its user is known. Thus, any employee in the venue can be reliably found from the location of his or her mobile device. In addition, targeted information, such as promotional information, can be sent to each mobile device for consideration by each customer during shopping at a retail venue. Still further, in the case where the mobile device is a data capture device for capturing data from the products in the venue, the control system is further operative for correlating or linking the associated device ID and the location of the mobile device with the data captured from the products.
Another aspect of this disclosure relates to a device association method, which is performed by moving and operating a mobile device by a user in a venue, by transmitting from the mobile device a device identifier (ID) that identifies the mobile device, by deploying a camera system in the venue, by imaging the user in the venue with the camera system, by prompting the user to perform a gesture, by controlling the camera system to image and detect the gesture and a location of the mobile device that is proximal to the detected gesture, by receiving the device ID from the mobile device, and by associating the device ID with the location of the mobile device.
Turning now to the drawings, reference numeral 10 in
As also shown in
As further shown in
As shown in
In accordance with this disclosure, each mobile device 20 transmits a device identifier (ID) that identifies the respective mobile device 20. The device ID is a string of numbers and/or letters that uniquely identifies each mobile device 20. The host server 16 receives the device IDs from all of the mobile devices 20, sequences the received device IDs along a queue in an order of priority, and distinguishes among all the received device IDs. The host server 16 prompts each user 44 to perform a gesture, as described below, controls the camera 40 in the vicinity of the user 44 to image and detect the gesture and, in turn, a location of each mobile device 20 that is proximal to the detected gesture, and associates the device ID with the location of each mobile device 20. Each mobile device 20 may transmit the device ID to the host server 16 either before the host server 16 prompts the user 44 to perform the gesture, or after the camera 40 has detected the gesture. The host server 16 may send a feedback indication to each user 44 that the device ID has been successfully associated with the location of the respective mobile device 20. For example, the feedback indication may be a visual signal on the display 32, or an auditory signal emitted as a beep by the mobile device 20.
The gesture is any visually prominent movement of a part of the user's body. For example, as shown in
Once the location of each mobile device 20 is known and has been associated with the respective device ID, the location of its respective user 44 is known. Thus, any employee in the venue 10 can be reliably found from the location of his or her mobile device 20. In addition, targeted information, such as promotional information, can be sent to each mobile device 20 for consideration by each customer on the display 32 during shopping at a retail venue. Still further, in the case where the mobile device 20 is a data capture device for capturing data from the products 1-6 in the venue 10, the host server 16 is further operative for correlating or linking the associated device ID and the location of the mobile device 20 with the data captured from the products 1-6.

In the foregoing specification, specific embodiments have been described. However, one of ordinary skill in the art appreciates that various modifications and changes can be made without departing from the scope of the invention as set forth in the claims below. Accordingly, the specification and figures are to be regarded in an illustrative rather than a restrictive sense, and all such modifications are intended to be included within the scope of present teachings.
The benefits, advantages, solutions to problems, and any element(s) that may cause any benefit, advantage, or solution to occur or become more pronounced are not to be construed as a critical, required, or essential features or elements of any or all the claims. The invention is defined solely by the appended claims including any amendments made during the pendency of this application and all equivalents of those claims as issued.
Moreover in this document, relational terms such as first and second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” “has,” “having,” “includes,” “including,” “contains,” “containing,” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises, has, includes, contains a list of elements does not include only those elements, but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises . . . a,” “has . . . a,” “includes . . . a,” or “contains . . . a,” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises, has, includes, or contains the element. The terms “a” and “an” are defined as one or more unless explicitly stated otherwise herein. The terms “substantially,” “essentially,” “approximately,” “about,” or any other version thereof, are defined as being close to as understood by one of ordinary skill in the art, and in one non-limiting embodiment the term is defined to be within 10%, in another embodiment within 5%, in another embodiment within 1%, and in another embodiment within 0.5%. The term “coupled” as used herein is defined as connected, although not necessarily directly and not necessarily mechanically. A device or structure that is “configured” in a certain way is configured in at least that way, but may also be configured in ways that are not listed.
It will be appreciated that some embodiments may be comprised of one or more generic or specialized processors (or “processing devices”) such as microprocessors, digital signal processors, customized processors, and field programmable gate arrays (FPGAs), and unique stored program instructions (including both software and firmware) that control the one or more processors to implement, in conjunction with certain non-processor circuits, some, most, or all of the functions of the method and/or apparatus described herein. Alternatively, some or all functions could be implemented by a state machine that has no stored program instructions, or in one or more application specific integrated circuits (ASICs), in which each function or some combinations of certain of the functions are implemented as custom logic. Of course, a combination of the two approaches could be used.
Moreover, an embodiment can be implemented as a computer-readable storage medium having computer readable code stored thereon for programming a computer (e.g., comprising a processor) to perform a method as described and claimed herein. Examples of such computer-readable storage mediums include, but are not limited to, a hard disk, a CD-ROM, an optical storage device, a magnetic storage device, a ROM (Read Only Memory), a PROM (Programmable Read Only Memory), an EPROM (Erasable Programmable Read Only Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory) and a Flash memory. Further, it is expected that one of ordinary skill, notwithstanding possibly significant effort and many design choices motivated by, for example, available time, current technology, and economic considerations, when guided by the concepts and principles disclosed herein, will be readily capable of generating such software instructions and programs and ICs with minimal experimentation.
The Abstract of the Disclosure is provided to allow the reader to quickly ascertain the nature of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the foregoing Detailed Description, it can be seen that various features are grouped together in various embodiments for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the claimed embodiments require more features than are expressly recited in each claim.
