Abstract:
1. A user terminal used in a terminal linkage system, the user terminal comprising: an image unit configured to output image data to be shared with a receiving terminal larger than the user terminal; a signal unit configured to transmit an image signal and a control signal to the receiving terminal, the image signal having the image data outputted from the image unit, and the control signal including position information of a touch means near the user terminal; a sensing unit configured to sense a position of the touch means when the touch means is near the user terminal or the touch means touches the user terminal; and a setting unit configured to set a plurality of sensing levels, wherein the sensing levels include a first sensing level for sensing the touch means when the touch means is near the user terminal and a second sensing level for sensing the touch means when the touch means touches the user terminal, the second sensing level is higher than the first sensing level, and the setting unit activates both of the first sensing level and the second sensing level when the user terminal and the receiving terminal are in linked operation and activities only the second sensing level when the user terminal and the receiving terminal are not in linked operation, wherein an image representing the position information of the touch means is displayed on the receiving terminal when the sensing unit senses the position of the touch means.
