KEYBOARDLESS COMPUTER

PROBLEM TO BE SOLVED: To make a computer keyboardless without installing a keyboard on which input keys and keys, which are usually provided in various computers, are arranged, to make a computer body small and light in weight, also to reduce the keying operation of a user's fingers by setting a virtual keyboard and to prevent tenosynovitis. SOLUTION: Myoelectric potential detecting means 10 which detect active potential of the keying operation of each finger based on the arrangement of keys 21, 22, 23,... of a virtual keyboard 20 are attached to user's both wrists 3 and 4, and a computer body 1 processes keying data based on an active potential detection signal from the means 10. The means 10 contains a keying data converting part 12 which converts an active potential detection signal into keying data. The body 1 is provided with a keying data inputting part 2 to which the keying data from the part 12 is inputted. For transmission of the keying data to the part 2, a keying data light emitting part 15 that is provided on the part 12 makes infrared LEDs emit light.
