Abstract
A portable communication device implements a position indication method to determine and convey the relative locations of other portable communication devices in a group. In one embodiment, the portable communication devices are equipped with a GPS sensor and the position indication method determines relative locations of devices using GPS location data. In another embodiment, the portable communication devices determine relative locations of devices using the strength of the received signal as a proxy for distance. In some embodiments, the relative location information is conveyed to each portable communication device by modifying the audio signal playback. For example, a 3D audio playback may be used to convey the relative location information. In other embodiments, other non-audible location indication may be provided on each portable communication device.
