1. An apparatus comprising:
- a first movement sensor configured to sense a first movement of the apparatus; and
a second movement sensor configured to sense a second movement of the apparatus,wherein, when the first movement sensor is powered-on while the second movement sensor is powered-off, the second movement sensor is then subsequently powered-on based on a first signal from the first movement sensor, wherein the first signal is generated in response to the first movement of the apparatus sensed by the first movement sensor,wherein, when the first movement sensor and the second movement sensor do not detect a movement of the apparatus within a predetermined time period while the first movement sensor and the second movement sensor are powered-on, the second movement sensor is then subsequently powered-off,wherein at least one of the first movement sensor and the second movement sensor comprises a gyro sensor, andwherein the apparatus generates a signal for controlling movement of a pointer displayed on a display device based on the first movement sensed by the first movement sensor and the second movement sensed by the second movement sensor, and transmits the generated signal to the display device.

Abstract
A remote control is provided including a plurality of sensors which sense movement of the remote control, and a control unit which turns on at least one sensor of the plurality of sensors and thereby senses movement of the remote control, and determines whether to turn on or off the remaining sensors according to whether or not the at least one sensor senses movement of the remote control. Consequently, battery consumption is reduced.
