A watch terminal for controlling an external device, comprising: a touchscreen; a laser pointer; a wireless communication unit configured to transceive data with the external device; and a sensing unit comprising a gyroscope sensor and an ultrasonic sensor, the sensing unit being configured to detect a rotation of the watch terminal; a user input unit configured to receive an input of a control command including a first and a second control command from a user; a controller configured to: receive an input to designate, via the sensing unit, four corners (800-1, 800-2, 800-3, 800-4) configuring a prescribed region corresponding to a screen of the external device when the watch terminal is rotated such that a laser of the laser pointer is pointed at each of the four corners, determine, via the sensing unit, whether the laser of the laser pointer faces the prescribed region, activate the laser pointer when the laser of the laser pointer faces the prescribed region, control, when the laser pointer is activated, a cursor to be outputted through the screen of the external device in response to the first control command in a first operating mode, deactivate the laser pointer when the laser of the laser pointer does not face the prescribed region, output, when the laser pointer is deactivated, at least one control button on the touchscreen for controlling the external device and control the external device in response to the second control command for selecting the control button in a second operating mode. a touchscreen; a laser pointer; a wireless communication unit configured to transceive data with the external device; and a sensing unit comprising a gyroscope sensor and an ultrasonic sensor, the sensing unit being configured to detect a rotation of the watch terminal; a user input unit configured to receive an input of a control command including a first and a second control command from a user; a controller configured to: receive an input to designate, via the sensing unit, four corners (800-1, 800-2, 800-3, 800-4) configuring a prescribed region corresponding to a screen of the external device when the watch terminal is rotated such that a laser of the laser pointer is pointed at each of the four corners, determine, via the sensing unit, whether the laser of the laser pointer faces the prescribed region, activate the laser pointer when the laser of the laser pointer faces the prescribed region, control, when the laser pointer is activated, a cursor to be outputted through the screen of the external device in response to the first control command in a first operating mode, deactivate the laser pointer when the laser of the laser pointer does not face the prescribed region, output, when the laser pointer is deactivated, at least one control button on the touchscreen for controlling the external device and control the external device in response to the second control command for selecting the control button in a second operating mode. receive an input to designate, via the sensing unit, four corners (800-1, 800-2, 800-3, 800-4) configuring a prescribed region corresponding to a screen of the external device when the watch terminal is rotated such that a laser of the laser pointer is pointed at each of the four corners, determine, via the sensing unit, whether the laser of the laser pointer faces the prescribed region, activate the laser pointer when the laser of the laser pointer faces the prescribed region, control, when the laser pointer is activated, a cursor to be outputted through the screen of the external device in response to the first control command in a first operating mode, deactivate the laser pointer when the laser of the laser pointer does not face the prescribed region, output, when the laser pointer is deactivated, at least one control button on the touchscreen for controlling the external device and control the external device in response to the second control command for selecting the control button in a second operating mode.
