Abstract

A wearable control apparatus is provided for implementing desired user commands on an electronic device. The apparatus comprises a mounting frame for attaching to one or more of the user'"'"'s fingers, various sensors for generating a command signal in response to user initiated input, and a physical link layer for performing processing on the command signals generated by the sensors and transmitting such processed signals to the electronic device to allow for control and navigation of such device. Preferably, the mounting frame is biometrically shaped to be ergonomically worn on the user'"'"'s index finger or embedded in a “smart-glove”, such that the wearer'"'"'s thumb can manipulate the sensors with minimal physical movement. The control apparatus can interface with the electronic device through a wire based or wireless connection, with an optional antenna for transmitting signals and power supply preferably attached to a user'"'"'s wrist to maximize ergonomics and the range of use of the invention.
