JOYSTICK

摘要

numeric-control devices; control members (graphic handlers). SUBSTANCE: joystick may be used in modern computer systems when manual data input is difficult to execute for operators whose motor activity is limited. To this end, differential temperature sensors are mounted on taper surface at cone top angle of 45 to 120 deg. and operator forms directional air flow by his mouth and nose in the course of breathing out thereby handling desired computer information by means of electromechanical temperature transducers without manual control. EFFECT: enlarged functional capabilities. 4 cl, 3 dwg
