Multimedia System Control.
Abstract
The initial objective of this research program was to investigate new ways of interactive communication between the human and the computer. In highly specialized and demanding environments such as computer aided design, computer aided manufacturing, information processing or battle management, an integrated workstation using other than the conventional keyboard, mouse or touch displays may be necessary. Specifically we propose to investigate the use of brain waves (electroencephalogram- EEG) to control cursor movements, such that a desired command could be selected from a given menu. We call this interface, the 'EEG mouse'. The computer user brain waves will have to be transmitted (we propose through radio telemetry) and processed by the workstation. However, the user will control the computer function by selecting functions from a menu by pure thought. No other computer input would have to be activated. With the advances in digital signal processing of the brain waves in real-time would be easily implemented in an I/O subsystem built around one of DSP chips. Our conclusion is that the neural network shows potential to discriminate between YES and NO answers using signal evoked responses. Further tuning of the signal processing is required to increase the reliability of the technique. (kt)
