ABSTRACT:
An electronic data input apparatus comprises a receptacle, a tube, a housing for electronic components, and a harness. The receptacle is operable for use in a user's mouth. The tube connects the receptacle to the housing, which is attached to the harness. A user wears the harness on the upper part of the torso, such that the receptacle is accessible to the mouth. A cable connects the electronic component housing to a computing element and establishes serial communication from the input apparatus to the computing element. The apparatus may provide the same function as a conventional mouse pointing device by allowing the user to control the motion of a pointer on an electronic display by breathing in to and out of the receptacle.
