Object location in three dimensional space using LED lights

摘要

A system and method of for performing an action at a device is disclosed. A first signal is sent into a first zone from a first light source, wherein the first signal identifies the first zone. The first signal is received at the device when the device is in the zone. The device determines from the received first signal that the device is in the first zone and performs the action at the device based on the device being in the first zone. A second variable light source may send a second signal into a second zone, wherein the second signal identifies the second zone. Triangulation may be performed to determine a location of the device using the first signal and the second signal. Alternately, a parameter of motion of the device may be determined using the received messages.
