Abstract
A controlling device location determination system and method. A controlling device such as a remote control has programming for transmitting a signal response to a plurality of control environments, each environment including a signaling device. Each signaling device in receipt of the signal request sends a signal response having a unique ID (associated with location definitions relating to the environment from which he signaling device is located) which is chosen to be characteristically attenuated by the surroundings of the environment (i.e., IR signals in a room). Because the controlling device can only be in one environment at a given time, and given the attenuation characteristics of the signal response from each signaling device, only one signal response will be received by the controlling device in each environment. Location definitions associated with the received unique ID may be used by programming in the controlling device to recall saved devices states, commands sets, macros, and even to dynamically generate commands based on the location information.
