CONVEYING INFORMATION ELECTRONICALLY

摘要

Apparatus for enabling a human to use his finger or tongue to convey information electronically. A set of at least four sensors define an action area within which the finger or tongue is manipulated to convey the information. The action area is no larger than one square inch. The sensors are arranged to produce signal patterns in response, other than via moving parts, to manipulation of the finger or tongue within the action area at finger or tongue pressures as small as zero. Circuitry is connected to respond to the signal patterns produced by the sensors and to provide information signals representing the information to be conveyed.
