Abstract
Techniques for generating a real-time 3D position of one device relative another device are described herein. In one embodiment, a first device may be equipped with one or more transmitters and receivers to collect location information based on direct localized signal transmission between the first device and a second device. The first device may also be equipped with an accelerometer and/or digital compasses to assist in resolving ambiguous locations when the first device and the second device are not at an alignment position. Each device may transmit part or all of its collected location information to another device to assist in obtaining the relative location. Alternatively, a separate server may receive the location information from the devices and calculate the relative location of each device based on the received location information.
