2D GESTURE LIGHT CONTROL BASED ON ULTRA SOUND ECHO DETECTION |
摘要 |
A lighting system comprising a lamp arranged to transform electricity into a light beam having properties such as intensity, color, color temperature, direction and beam cone angle; a light control means arranged to adjust said light beam properties; a plurality of ultrasonic transmitters arranged to transmit ultrasonic signals; a plurality of ultrasonic receivers arranged to receive reflected ultrasonic signals; and a processing means arranged to send an ultrasonic pulse sequentially through each of said transmitters and to determine after each pulse is sent which ones of said receivers receive a reflected ultrasonic signal with an amplitude exceeding a predetermined threshold within a predetermined period, and to send control signals to said light control means in dependence of said determination. |
