Abstract
An apparatus for controlling a plurality of devices in response to biopotentials produced by gestures made by a user. The apparatus includes a sensor ( ) applied to the user for producing an input signal representing the biopotentials, wherein the input signal changes as a function of chances in the biopotentials. A plurality of bandpass filters ( ) are responsive to the input signal, and each of the filters produces respective frequency signals. A processor ( ) is responsive to the frequency signals from each of the filters and generates control signals in response to gestures made by the user to command operation of a device ( ). A method is also provided that analyzes the high frequency signals with respect to a plurality of gesture models to detect a plurality of gestures being made by the user and then, provides control signals to a device ( ) for controlling the device in response to a plurality of gestures made by the user. The method includes detecting a short eyebrow lift, a long eyebrow lift, a jaw clench, a short eyebrow drop, right and left eye glances and multiple eye blink gestures of the user. In another aspect of the invention, the method provides continuous analog control signals in response to eye gestures of the user.
