Abstract

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 which is chosen to be characteristically attenuated by the surroundings of the environment. 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.

Claims

1. In an environment including a plurality of appliances, a method comprising:

accepting user input into a portable controlling device indicative of an operation to be performed by a one or more of the plurality of appliances;

simultaneously receiving at the portable controlling device from each of a plurality of different signaling devices a wireless signal wherein the simultaneously received wireless signals function to provide a unique wireless signal fingerprint in each of a plurality of different locations of the portable controlling device relative to the plurality of appliances in the environment;

using a unique wireless signal fingerprint received from the plurality of signaling devices to determine a current location of the portable controlling device relative to the plurality of appliances in the environment;

selecting from a database of commands available to the portable controlling device one or more commands to be transmitted to the one or more of the plurality of appliances as a function of the user input accepted into the portable controlling device and the determined location of the portable controlling device relative to the plurality of appliances in the environment; and

transmitting the selected one or more commands to cause the one or more of the plurality of appliances to perform the operation.

2. The method as recited in claim 1, wherein each of the plurality of different signaling devices comprise a wireless access point having a network address.

3. The method as recited in claim 1, wherein each of the unique wireless signal fingerprints comprises at least one of a network ID, access point name, and appliance address associated with the wireless signal received from each of the plurality of different signaling devices.

4. The method as recited in claim 1, wherein each of the unique wireless signal fingerprints comprises at least a signal strength associated with the wireless signal received from each of the plurality of different signaling devices.

5. The method as recited in claim 1, wherein the portable controlling device comprises at least one of:

a remote control, a portable phone, a wireless capable PDA, a tablet PC, a Smart Display, and a home appliance.

6. The method as recited in claim 1, wherein the portable controlling device transmits the selected one or more commands to cause the one or more of the plurality of appliances to perform the operation using a wireless communication protocol.

7. The method as recited in claim 6, wherein the wireless communication protocol comprises an infrared based communication protocol.

8. The method as recited in claim 6, wherein the wireless communication protocol comprises a radio frequency based communication protocol.
