Subject now types the digits one through nine on his knee, and the gestures are also recognized as being equivalent to typing on the actual keypad. Numbers are displayed on the computer terminal as they are entered by appropriate gestures typed onto the subject's knee. The complex EMG signals are also displayed on the computer screen as dyanamic XY graphs. The numbers which are typed appear in the terminal window and the nerve signals are displayed on the graphics window. Internal to the computer, the pattern recognition software interprets the complex signals and decodes each gesture, outputting symbolic information representing the keys as they are pressed on the imaginary keypad.
