Abstract

A multimedia playing device includes a central processing unit, a plurality of sensors electrically coupled to the central processing unit, and an output unit electrically coupled to the central processing unit. The plurality of sensors are operated together with the central processing unit, such that after the sensors detect different hand movements of a user, the central processing unit reads and determines the hand movement and transmits related control signals to the output unit according to different hand movements to achieve the effects of using a hand posture to control related functional movements and enhancing the convenience of using the multimedia playing device.

Claims (18)
