Electronic apparatus, control method thereof, remote control apparatus, and control method thereof
First Claim
1. An electronic apparatus which is configured to transmit remote control information to an external device, the electronic apparatus comprising:
- a user input interface configured to receive a user input;
a sensing unit configured to sense a movement of the electronic apparatus, the sensing unit comprising at least one of a gyro sensor, an acceleration sensor, and a geomagnetic sensor;
a communication unit configured to establish communication with the external device anda control unit configured to control the electronic apparatus to transmit information corresponding to the sensed movement of the electronic apparatus to the external device, to control the sensing unit to operate in a power saving mode in response to detecting a predefined user input via the user input interface, to control the electronic apparatus to transmit information corresponding to a user input received via the user input interface while the sensing unit operates in the power saving mode, to control the sensing unit to switch from the power saving mode to an active mode in response to sensing a spatial movement of the electronic apparatus by the sensing unit in the power saving mode,wherein, after the sensing unit switches to the active mode, the control unit is configured to control the sensing unit to re-switch from the active mode to the power saving mode in response to receiving a predefined signal via the communication unit from the external device while the sensing unit is operating in the active mode, andwherein the sensing unit consumes less power in the power saving mode than in the active mode.

Abstract
An electronic apparatus, control method thereof, remote control apparatus that controls the electronic apparatus, and control method thereof. The remote control apparatus includes a communication unit which communicates with the electronic apparatus; a user input unit which receives a user button selection indicating an input button; a sensing unit which senses movement of the remote control apparatus; and a control unit which controls the communication unit to transmit information about the user button selection to perform a function corresponding to the input button if the remote control apparatus is in a button input mode, and to transmit information about the movement of the remote control apparatus to the electronic apparatus to control the electronic apparatus by the movement if the remote control apparatus is in a motion recognition mode. Accordingly, controlling a game or a multimedia content is easier, and the user is provided with a new and interesting experience.
