System for remote communication with an addressable target using a generalized pointing device
First Claim
1. A system for communication with electronic appliances, comprising:
- a pointing device distally spaced from each of said appliances, wherein said pointing device is adapted to initiate communication with any one of said appliances without the use of appliance-specific codes by sending a selection signal to select said one of said appliances; and
an appliance interface locally coupled to each of said appliances and adapted to detect a signal sent from said pointing device and convert said detected signal into a command format uniquely recognized by one of said appliances.

Abstract
A system for communication with addressable electronically-controllable appliances using a generalized pointing device is provided. The system includes a pointing device that can communicate with dissimilar types of target appliances from a position remote from those appliances and an appliance interface that makes the target appliances compatible with the pointing device. Use of the system is believed to allow the convenience associated with use of a computer'"'"'s graphical user interface (GUI) to be realized in communication with physical objects, i.e. the target appliances. In an embodiment for one-way communication from a pointing device to a target appliance, the pointing device may comprise an actuator, an input-output interface, and a transmitter. In an embodiment configured for two-way communication between the pointing device and an appliance, the pointing device may further include a receiver. The appliance interface may include a receiver, an input/output interface, and a driver to convert received pointer command signals to corresponding functions of the appliance. In an embodiment configured for two-way communication, the appliance interface may further include a transmitter. The system may be configured for transmission using optical signals, radio-frequency signals, or both.

an appliance-side receiver coupled to detect the signal; and
a driver coupled to convert the signal into an operating system signal compatible with an operating system of the appliance.
-
-
5. The system as recited in claim 1, wherein said pointing device is further adapted to maintain communication with the one of said appliances with and/or without the existence of a line-of-sight path between said pointing device and the one of said appliances.
-
6. The system as recited in claim 1, wherein said pointing device is further adapted to receive appliance-specific information transmitted by said one of the appliances.
-
7. The system as recited in claim 6, wherein said pointing device comprises a display screen, and said appliance-specific information appears on said display screen in the form of a menu.
-
8. The system as recited in claim 1, wherein said pointing device comprises:
-
said actuator which, when actuated, generates a pointer event;
a pointer-side input/output (I/O) interface coupled to said actuator, wherein said pointer-side I/O interface is adapted to create said signal unique to said pointer event; and
a pointer-side transmitter coupled to said pointer I/O interface, wherein said pointer-side transmitter is adapted to transmit said signal to the appliance interface.
-
-
9. The system as recited in claim 8, wherein said actuator comprises a button, knob, key, trackball, or scroll wheel.
-
10. The system as recited in claim 8, wherein said pointer-side I/O interface comprises a processor and memory locations.
-
11. The system as recited in claim 8, wherein said appliance interface comprises:
-
said appliance-side receiver for receiving said signal;
an appliance-side I/O interface coupled to said appliance-side receiver, wherein said appliance-side I/O interface is adapted to recognize the pointer event represented by said signal; and
said driver coupled to said appliance-side I/O interface for translating said pointer event into a corresponding appliance-specific event, and for forwarding an instruction for the appliance-specific event to appropriate circuitry within the appliance.
-
-
12. The system as recited in claim 11, wherein said pointer-side transmitter comprises a photodiode or laser diode, and said appliance-side receiver comprises a photodetector.
-
13. The system as recited in claim 11, wherein said pointer-side transmitter and said appliance-side receiver comprise antennas.
-
14. The system as recited in claim 11, wherein said driver comprises memory locations containing information regarding a correspondence between the pointer events and the appliance-specific events.
-
15. The system as recited in claim 11, wherein said driver is configured within said appliance-side I/O interface.
-
16. The system as recited in claim 11, wherein said appliance interface further comprises a visible indicator that is illuminated when an associated one of said appliances is selected.
-
17. The system as recited in claim 11, wherein:
-
said pointer-side transmitter comprises an optical transmitter and a radio-frequency (RF) transmitter; and
said appliance-side receiver comprises an optical receiver and an RF receiver.
-
-
18. The system as recited in claim 17, further comprising a switch coupled between the pointer-side I/O interface and the pointer-side transmitter, such that said signal may be switched onto either the optical transmitter or the RF transmitter.
-
19. The system as recited in claim 17, wherein said actuator is coupled to the optical transmitter through the pointer-side I/O interface, and wherein said actuator is an appliance select actuator, and wherein an additional actuator is coupled to the RF transmitter portion through the pointer-side I/O interface.
