The Air Super Piano is a virtual piano playing system implemented using laser or photoelectric sensor technology. It can play music in the air through hand movements without an actual physical keyboard. The super air-isolating piano uses infrared obstacle avoidance to detect the presence of hands, thereby triggering the buzzer to sound. The human hand triggers different infrared obstacle avoidance sensors, thereby triggering the buzzer to emit tones of do, re, mi, fa, so, la, xi, simulating the effect of playing a piano.
