Electronic apparatus, control method thereof, remote control apparatus, and control method thereof
First Claim
1. An electronic system comprising:
- a first electronic apparatus comprising;
a plurality of buttons comprising a plurality of direction keys;
a sensing unit operable in one of an active mode and a power saving mode, configured to sense a movement of the first electronic apparatus;
the sensing unit comprising at least one from among a gyro sensor, an acceleration sensor, and a geomagnetic sensor;
a first communication unit configured to establish communication with a second electronic apparatus; and
a first control unit configured to transmit information corresponding to the movement of the first electronic apparatus which is sensed by the sensing unit in the active mode, the information being transmitted to the second electronic apparatus via the first communication unit, andthe second electronic apparatus comprising;
a display;
a second communication unit configured to establish communication with the first electronic apparatus; and
a second control unit configured to control the display to display a pointer in a pointing mode based on the information corresponding to the movement of the first electronic apparatus transmitted from the first electronic apparatus and in response to switching from the pointing mode to a non-pointing mode, to transmit a control signal via the second communication unit to the first electronic apparatus so that the sensing unit operates in the power saving mode,wherein 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.
