TONGUE BASED CONTROL DEVICE FOR TRANSFERRING KEYBOARD COMMANDS

摘要

A device (300) for transferring keyboard commands from a user to an electronic apparatus or machine. An arm (302) intended to be carried by the user as a headset, is provided with signal sensors (304a, b,c) responding to the presence or pressure of the user' s tongue by emitting an electric signal or impulse. A signal unit (306) registers and converts signals from the sensors into corresponding keyboard commands which are then input to the electronic device or machine (308). The device thus basically works as a keyboard where the signal sensors constitute keys that can be operated solely by the tongue, i.e. without involving the hands.
