An exemplary dynamic virtual boundary system accesses a positioning signal, a corresponding correction signal, and data defining a user-specified geographic boundary configured to change in real time. The positioning signal is generated by a satellite within a satellite-based positioning system and is received by a real-time tracking device carried by a subject. The correction signal is generated by a terrestrial positioning enhancement system and is also received by the device. Based on the positioning and correction signals, the dynamic virtual boundary system continuously determines a refined geolocation of the device and continuously monitors whether the refined geolocation is within a predetermined distance of the boundary as the boundary changes in real time. In response to a determination during the monitoring that the refined geolocation is within the predetermined distance, the dynamic virtual boundary system provides an alert to assist in constraining the subject within an area defined by the boundary.

There is provided an eyeglasses-type wearable terminal that causes a user to more reliably recognize the position of a predetermined object, which includes an image capturing unit that captures the periphery of the user. The eyeglasses-type wearable terminal also includes a determiner that determines whether a predetermined target object is included in a video acquired by image capturing using the image capturing unit. The eyeglasses-type wearable terminal further includes a display unit that displays the position of the predetermined target object in a case in which the determiner determines that the predetermined target object is included.

A method for detecting allergic reaction and alerting a guardian device includes registering a wearable device to associate the wearable device with the guardian device. The wearable device then monitors vital signs to determine whether the vital signs are within an acceptable range. Based on the vital signs being outside the acceptable range, the wearable device sends an alert to the guardian device and determines whether a confirmation signal is received from the guardian device.

A method for providing incentives based on geolocation of mobile devices. The method includes storing, by a server, data including merchant information of merchants and points of interest, and associated incentive information. The method includes determining, based on communication with user's device of a user, a first location of the mobile device. The method includes determining, based on the first location, a first subset of merchants and associated first subset of incentives. The method includes communicating merchant data, including information on the first subsets of merchants and incentives, to the mobile device. The method includes communicating to the mobile device, in response to a determination that the mobile device is inside a geofence associated with at least one of the first subset of merchants, additional information on the at least one of the first subset of merchants, the additional information comprising one or more related incentives.

A method and system for presenting location-based alerts on mobile devices is discussed. The method includes tracking user locations of users based on mobile device locations of mobile devices associated with the users. The mobile device locations can be determined based on location data transmissions from the mobile devices, with respective transmission lengths based on user preferences. The method includes presenting an interactive map interface for display on a first mobile device of a first user. The interactive map interface can display, based on the tracking, names of locations and the user locations. The interactive map interface can display pictures, each associated with a respective location or a user. In response to a determination, based on the tracking, that a second mobile device of a second user has arrived at a location defined by a geofence, a location notification can be pushed to the first mobile device.

A method and system for presenting location information on mobile devices is discussed. The method includes tracking, at a device associated with a user, mobile locations of mobile devices associated with the user, the mobile locations based on server data received from a location server. The method includes displaying an interactive map via a User Interface (UI) on a device display of the device, where the interactive map can indicate mobile locations with respect to names of physical locations. The method includes displaying a control element, on the UI, for receiving a user selection to control a first mobile device of the one or more mobile devices. The method also includes communicating, based on receiving the user selection, with the location server to remotely control the first mobile device.

A method and system for effecting changes on a mobile device. The method includes determining a physical location of a point of interest. The method includes automatically generating a geofence proximate to the point of interest based on the determined physical location. The method includes detecting when the mobile device enters the geofence. The method includes tracking a duration of time spent within the geofence by the mobile device. The method also includes effecting a change on the mobile device based on the duration of time spent within the geofence by the mobile device.

A method and system for presenting location information on mobile devices is discussed. The method includes tracking, at a mobile device associated with a user, mobile device locations of additional mobile devices associated with additional users. Each of the mobile device locations can be determined based on data indicating location data transmissions of respective additional mobile devices. The method includes providing an interactive map interface on a device display on the mobile device, the interactive map interface indicating, based on the tracking, location representations of locations and user representations of the additional users. The interactive map interface indicates a geofence generated using a location selected by the user. The method also includes displaying, responsive to a determination based on the tracking that one of the mobile devices has entered an area of the geofence, an alert on the device display.

A method and system for effecting changes on a mobile device. The method includes determining a physical location of a point of interest. The method includes automatically generating a geofence proximate to the point of interest based on the determined physical location of the point of interest. The method includes detecting when the mobile device enters the geofence. The method includes tracking a current velocity of a mobile device. The method also includes effecting a change on the mobile device based on the current velocity of the mobile device within the geofence.
