Abstract: A motion recognition apparatus and a control method thereof, capable of controlling and operating a controlled device by determining a gesture variation of a user to replace conventional finger touch for a user interface. The motion recognition apparatus includes a first device, a second device and a controlled device wirelessly connected to the first device and the second device. The first device detects a gesture variation of a user. The second device calculates the number of gesture variations and outputs a corresponding control signal. The second device includes a motion recognition unit and a fast communication unit, enabling the controlled device to receive the control signal and operate according to the gesture variation of the user. Accordingly, the user interface becomes more user-friendly and makes the controlled device more controllable and the Internet of Things (IoT) more applicable.
