## Background
BACKGROUND
The present disclosure relates to a computer implemented method and system for identification between users in proximity to each other. Identification between two or more users in a crowded pedestrian or vehicular traffic area can be challenging. For instance, it can be difficult to identify a party even if a location is agreed upon since the location may have many people in the vicinity. Also, a car service can be similarly difficult to identify when many similar looking vehicles are queued for providing transportation services. Thus, when arranging for a vehicle transportation at a busy location or business location, or waiting to meet a contact at a busy location, for example, an airport, it can be difficult to properly identify the vehicle or person which a person is meeting. In one example, calling a party on a mobile device and describing what a person is wearing or in another instance holding a sign, or describing a vehicle is not always possible and is time consuming and inefficient. In one example, people can be in a common attire (e.g., customary dress, uniform, typical work attire) or a vehicle can be similar to many other vehicles or part of a fleet of common vehicles, making visual distinction and description difficult for identification purposes. In another example, a map on a mobile device display can depict the location of one or more devices and is typically not very effective when the users are in close proximity to each other as the identifiers (e.g., dots) on the map can appear over one another or as a cluster and are not effective for distinguishing direction when the users' are in close proximity.

DETAILED DESCRIPTION
Referring to FIGS. 1 and 2 a system 10 and method 100 according to an embodiment of the present disclosure for proximity aware identification for two or more users using electronic devices is described. The method 100 includes determining a location of a second device 70 used by a second user 54 relative to a first device 60 used by a first user 50, as in block 104. In the present example, the method includes the first user using the first device, moving to a location (or specified proximity or vicinity) of the second user using the second device. For example, the first user can be a car service 210 (or a ride sharing service) with a mobile device or car mounted computer device as a first device. In another instance, a first user can be a tour leader assembling a group of tourist. In another instance, the first and second users can be any two persons seeking to identify each other in a crowded or high density location. Other examples and applications will be described herein.
The locations of the first and second devices can be obtained using a positioning or location technique 84, for example, a GPS (Global Positioning System). The second user's location can be determined and the vicinity 52 of the second user identified. In one example, the second device can be a mobile device used by the second user who is a passenger utilizing the car service or ride sharing service.
The first and second devices 60, 70, respectively, each include a computer system 20, depicted in FIG. 1. The first and second devices 60, 70 can be a computer or a mobile device, or other types of computer devices. The first and second devices 60, 70 each include a proximity identification application 62 for generating a unique identifier or symbol, or can access a remote service (which can include one or more servers) using a communications network 80, e.g., the Internet. The proximity identification application 62 embodying the method of the present disclosure can be included on the first and second devices 60, 70, as shown in FIG. 1. Alternatively, the proximity identification application can be different versions for a client such as a client version, and a server version for a service provider. The proximity identification application can be a separate application, and alternatively can be an add on or part of (or integral with) an existing location application or service, and in another embodiment can be accessed remotely from a remote server 94 as part of a service 90.
The method 100 includes determining a symbol for identification on the first device, as in block 108. The symbol can be any visual representation for identification, for display on the first device, as in block 112. In one embodiment according to the present disclosure, the first user is a car service which can determine a symbol 64 which is not in use in the second user's vicinity. In other words, the symbol is chosen by the car service or ride sharing service to exclude other vehicles of the car service in the vicinity of the passenger. Alternatively, the symbol can be selected by the ride sharing service from a group of symbols excluding symbols of the group which are in current use in a vicinity of the passenger using the second device. In another example, the first or the second user can select a symbol from a group of symbols. The symbol can be verified as not being used in the vicinity or specified proximity of the second user, before the symbol is accepted by the users.
The method 100 includes detecting the second device 70 within a specified proximity 52 of the first user 50 and the first device 60, as in block 116. The second device can be located using the location technique 84.
An image 204 is sent including the symbol 64 from the first device 60 to the second device 70, as in block 120. In one example, the car service 210 can include a vehicle 214 which enters the vicinity 52 of the second user, as shown in FIG. 3.
The second device receives the image and displays the symbol, as in block 124. The second device 70 can display the image on a display 78.
A location of the second device is indicated on a display 68 of the first device 60 depicting a relative location of the first device to the second device using the symbol 64, as in block 128.
A location of the first device is indicated on a display of the second device depicting a relative location of the first device to the second device, as in block 132. The first device and the second devices include the symbol for identification by users of the first and second devices. Thus, the users' of the first and second devices 50, 54, respectively, each have the same symbol on their respective devices, and can, in one example, hold the device up for the other user to see the symbol and identify the other user.
In one embodiment, the method can obtain coordinates of the first device via a proximity technology technique, for example, GPS (Global Positioning System). The location of the first device can be mapped on the display on the second device, and the location of the first device can be adjusted relative to the second device based on movement of the first device.
In a related example to the above example, in one embodiment, using an analytics component 220 of the present disclosure, predictive analytics, for example based on congestion of pedestrian traffic, vehicle traffic, or an event, or known services at a location, can be applied to predict where the first user will be located with respect to the second user (and/or vice versa). In one example, the analytics component can be implemented on an analytics server, which may be remote to the physical location of the application. Thereby, predictively analyzing data pertaining to the location of the second device, the method and system of the present disclosure can approximate an arrival location for a user of the first device respective to the location of the second device.
For example, considering congestion (e.g., population density, pedestrian traffic, or vehicular traffic) in the specified vicinity, an estimated location of a user can be indicated using the symbol on a map displayed by a device. Correction can be implemented based on GPS. This can be particularly useful between updates of location from the GPS system.
In one embodiment, a first and second user can be embodied as vendor and vendee, a tour guide, or anyone or more persons looking to identify each other in a vicinity. The first and second users can verify the identity of each other by, for example, the first user sending a request to the second user for a confirmation from the second user before sending an image including a symbol from the first user to the second user. The confirmation can verify that the second user intends to contact the first user and is the party that wants an identification symbol for identifying the first user. Thus, the method and system of the present disclosure provides for verifying an identify of a first user of the first device to a second user of the second device, and can also verify an identify of the second user of the second device to the first user. As described above, the verification of identity can include sending a request from the first user from the first device to the second user of the second device, and receiving a confirmation from the second user verifying an identity of the second user, which can simply include the acceptance of the request.
Alternatively, profiles can be maintained by a service provider, providing the method of the present disclosure as a service. The first and second users can be verified based on their profiles maintained in the service provider's computer system. The stored profiles enable both users (or a plurality of users) to be verified, for example, a customer and an authorized service provider. The verified user can thus be sent an image including the symbol to a verified mobile device for the user. In one example, the service provider can generate a symbol for use by the users, and determine the other symbols in use in the vicinity to confirm that duplicate symbols are not being issues in the same vicinity. If the service provider determines that a symbol is already in use in the vicinity, another symbol can be generated for use in the same vicinity. Thus, the above technique ensures that the correct user receives the symbol, and that other users in the area or vicinity do not receive duplicate symbols. Also, the profiles can be analyzed to determine previously used and/or agreed upon symbols for identification. The process can then use a previously agreed upon symbol or previously used symbol to facilitate identification. In one embodiment, the verification of a user and the assignment of a symbol for identification can be determined and implemented by the analytics component.
Referring to FIGS. 1, 3 and 4 a method 300 based on the system 10 according to an embodiment of the present disclosure for proximity aware identification for two or more users using electronic devices is described. The present method 300 is directed toward a car service or ride sharing service, however, some of the steps of the method 300 are similar to the method 200 described above. In the present example, the method 300 includes a car or transportation (ride) service 210 receiving a request from a potential passenger to provide transportation which includes the passenger's location, as in block 304. The potential passenger is an embodiment of a second user 54. The car service, for example, includes a dispatch computer 212 for receiving requests from potential passengers and coordinating passenger pick up. Alternatively, a mobile device in a ride service vehicle can be used for this function. The dispatch computer can receive a request for transportation from a potential passenger, receive the passengers location, determine or suggest a symbol associated with the potential passenger which excludes symbols being used by the car service in the vicinity of the passenger.
After receiving the passenger's request and location, the car service can determine the passenger's vicinity (block 308). The car service can determine a symbol for use by the vehicle operator and the passenger, excluding any symbols already in use in the vicinity, as in block 312. If the symbol is being used in the passenger's vicinity (block 314) the method returns to block 312 to determine another symbol. If the symbol is not being used in the passenger's vicinity (block 314), the method proceeds to block 316.
The dispatch computer can send an image including the symbol to a vehicle operator's device as an embodiment of a first user 50 and a first device 60 who is operating the vehicle 214. The dispatch computer can also send the image including the symbol to a passenger's mobile device as an embodiment of a second user 54 and a second device 70. The vehicle operator in the vehicle 214 proceeds to the passenger.
The passenger receives the image 204 and symbol 64 on the display 78 of a device, e.g., the second device 70. The device can display the symbol 64 on the display 78, as in block 320.
The location of the passenger relative to the vehicle operator can be displayed on the passengers device using the symbol, as in block 324. Likewise, the location of the vehicle operator and vehicle relative to the passenger can be displayed on the vehicle operators device using the symbol, as in block 328. For example, two symbols can be shown on the device in relative position to each other. The vehicle operator's symbol can be adjusted to continually update the operator's location. If both the passenger and the operator are moving, both can be continually updated to depict their relative locations.
The passenger and vehicle operator can display the symbol displayed on their devices to others in the vicinity thereby using the symbol display to identify each other, as in block 332.
In one embodiment, using an analytics component of the present disclosure, predictive analytics, for example, based on traffic movement, can be applied to predict where the vehicle and vehicle operator of the vehicle is located. For example, considering traffic patterns, no parking or standing areas, emergency vehicles. Correction can be implemented based on GPS. This can be particularly useful between updates of location from the GPS system.
The present disclosure provides a process and a system for enabling a user to identify a vehicle or operator of a vehicle in a cluster of visually similar vehicles in a busy area. In one example, the present disclosure eliminates a potential passenger waiting for a car service from having to call the operator of the vehicle, receive a description of the vehicle or of the operator and try to identify each other. Further, the present disclosure enables users within a vicinity which is crowded with similar users to identify each other where typical map tracking would not enable identification because, for example, too many people are crowded in the immediate area or to many similar vehicles are in the same area.
The present disclosure provides a unique, matching visual notification, that two or more parties can use when they are in a specified proximity to one another. In one example, the parties can display the symbol on their devices in the direction of where the other party is located and the other party can do the same to facilitate identification between the parties.
In one embodiment, the symbol can be augmented to change visually as the parties approach each other, for instance, a change of color or flashing as the parties reach within a set distance from each other.
In one embodiment, a potential passenger of a car service is on a crowded street and numerous cars, taxis, and car service vehicles, the potential passenger can use the unique symbol according to the embodiments of the present disclosure. In one example, the symbol can be a bright green, flashing circle to use for mutual identification. The application can use a library of unique symbols unique to the service and can verify that the symbol will not be re-used in the same proximity. In one example, the car service vehicle can be indicated on the passenger's device within 100 feet of the potential passenger's location (e.g., using GPS or other proximity technology). The operator of the vehicle and the potential passenger can hold their respective devices in the air for mutual identification.
In one embodiment, a customer or potential passenger of a car service can have profiles which can be maintained in the service provider's computer system. The stored profiles enable a user to be verified and a car service operator to be selected, to provide an authorized service provider. The verified user can thus be sent an image including the symbol to a verified mobile device for the user. Also, the profiles can be analyzed to determine previously used and/or agreed upon symbols for identification. The process can then use a previously agreed upon symbol or previously used symbol to facilitate identification.
The method and process of the embodiments of the present disclosure can be implemented using the proximity identification application 62 shown in FIG. 1. The method can also be provided as a service which can be remote, for instance, including an application residing on a remote server exemplified by remote server 94.

Other examples can include wearable devices that provide real time display of data. The first and/or second user can be wearing the wearable. The embodiments of the present disclosure can be implemented on the wearable(s) as a first and/or second device, 60, 70, respectively. In another embodiment, augmented reality techniques can be used where a map, image, or symbols, or indicator, can overlay an image on a device (such as a phone, watch, or camera, or tablet), to display a symbol as in the embodiments of the present disclosure.
In another example, the first and second users could be operators of vehicles and the vehicles have respective displays that can show a symbol for identification by the users to identify the users and their vehicles. The vehicles could include bicycles, motorcycles; mopeds, or cars. In another example, one user could have a mobile device and a second user could display a symbol on an second device mounted on their house to identify each other. In this example, a first user can be operating a vehicle and want to identify a second user in their home.
