Abstract : A progress report is presented of a project directed toward the evaluation and implementation of man-machine command and control procedures that incorporate neuroelectric signals directly derived from the brain. This document first reports on the current state of the project. A first milestone has been reached: one such man-machine loop has been operating for several months at nearly operational performance levels. In the communication protocol of this 'MASTER-ROBOT' team, the computer robot executes commands encoded in the master's occipital brain waves (as SINGLE OPOCH VISUAL EVOKED RESPONSES). To send a command the master visually selects the corresponding command symbol from a displayed set. Symbol pattern and color have been used in the command alphabet.
