ABSTRACT:
A method and apparatus for assisting a user to control a device in response to a combination of electroencephalographic and electromyographic potentials. The user selects a number of reference frequencies in a range of from 0.5 Hz to 45 Hz defining a like number of control signals. A digital lock-in amplifier is used with a moving average time window filter to produce control signals which are presented to the user. Control system responsiveness is controlled by adjusting the lengths of the moving average time windows. A phase-locked loop is closed around each control signal and is used to track the shifting frequencies of the control signals. The user is able to sense and control changes in the magnitude and frequency of the control signals in the control of the device. By sensing the changes in the magnitude and frequency of the control signals, the user is able to learn a combination of mental and/or physical activities for which changes in the electroencephalographic and electromyographic biopotentials are correlated to control of the device.
