ABSTRACT:
An input device for a computer includes a mouthpiece and a interface for coupling the mouthpiece to the computer. The mouthpiece includes a plurality of air cells arranged in rows for entering commands to the computer. The are each assigned a command and a chosen command can be entered by inhaling or exhaling through the corresponding cell. The interface identifies which cell a user has selected and produces a distinct digital signal corresponding to that cell. In the preferred embodiment, a MIDI interface is used which discriminates between the different sounds produced by each cell. An on-screen keyboard is selectively displayed on the display screen of the computer to aid a user in selecting and entering commands into the computer. Software allows the user to interact and control different programs loaded on the computer. Potential users include the physically-challenged, astronauts, SCUBA divers, surgeons, construction workers, and musicians.
