Abstract

A wearable universal user interface device is provided for interacting with a variety of electronic apparatus. The interface device includes various sensors, such as a temperature sensor, pressure sensor, and a two-dimensional quadrant force sensor. The interface device also includes processing circuitry, a wireless transmitter, and an optional receiver. In the preferred embodiment, the interface device is in the form of a ring adapted to be worn on the finger of a user. The device is operated by the wearer'"'"'s fingers and thumb. Preferably, the interface device includes an internally mounted pressure sensor and an externally mounted two-dimensional force sensor. The body of the ring itself serves as an omnidirectional loop antenna for transmission and reception of signals. Representative applications of the interface device include use as a wireless computer mouse, a remote controller for a television, stereo, VCR, or the like.

Claims

1. A context-sensitive user interface for interacting with at least one electronic device of interest to a user, the interface comprising:

at least one sensor for receiving input from the user and producing sensor signals in response thereto;

a memory for storing a set of instructions and identification information;

a receiver for receiving signals from the at least one electronic device when in close proximity thereto to provide context information to the user interface;

a processor in communication with the memory, the receiver, and the at least one sensor for executing the set of instructions, the processor producing control commands for the at least one electronic device based on the context information, the control commands being responsive to the sensor signals;

a transmitter in communication with the processor for transmitting the identification information and the control commands to the electronic device; and

at least one antenna in communication with the transmitter for transmitting a signal to the at least one electronic device representative of the identification information and the control commands, wherein the at least one sensor, the memory, the processor, the receiver, and the transmitter are mounted on a device wearable by the user.

2. The user interface of claim 1 wherein the processor is a microprocessor.

3. The user interface of claim 1 wherein the at least one sensor comprises a two-dimensional force sensor.

4. The user interface of claim 1 wherein the at least one sensor, the memory, the processor, the receiver and the transmitter are mounted on a ring wearable on a finger of the user.

5. The user interface of claim 4 wherein the ring functions as one of the at least one antennas.

6. The user interface of claim 1 wherein the at least one antenna comprises a loop antenna.

7. The user interface of claim 1 wherein the at least one sensor produces a signal when the user flexes a finger.

8. A wearable user interface for communicating with a plurality of electronic devices of interest to a user, the interface comprising:
