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 (22) 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 (28, 30, 32) are responsive to the input signal, and each of the filters produces respective frequency signals. A processor (38) 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 (40). 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 (40) for controlling the device in response to a plurality of gestures made by the user.
