METHOD AND APPARATUS USING GEOFENCE TO TRACK INDIVIDUAL GROUP MEMBERS

摘要

A method is provided to track geolocations of multiple mobile location tracking enabled devices, each such device associated with at least one member of a group of subjects; one of the devices sends a map image of a real-world location and indicia of geofence to each of the other devices; each of multiple devices sends its geolocation to at least one other device in the group; the at least one device in the group displays the respective geolocations of the other devices relative to the map image and relative to the geofence image; an alert is generated by the at least one other device in the group in response to a determination that at least one of the devices in the group is disposed outside the geofence or within a prescribed distance from the geofence.
