Other voice control technologies: People who use a new kind of wheelchair can now move it using their tongue rather than their hands. Mechanical engineers and computer scientists worked together to develop the wheelchair controls. Moving the tongue changes the air pressure in the users' ears. In the new wheelchair design, a microphone near the ears picks up the change in air pressure and issues commands to a computer chip, which moves the chair in a specified direction.
