DISPLAY DEVICE AND CONTROL METHOD THEREOF

摘要

A display device and a control method thereof are disclosed. A display device and a control method thereof according to the present invention comprise a display unit displaying an object; a receiver receiving a wireless signal from a three dimensional (3D) pointing device recognizing a three dimensional motion; and a controller calculating a trajectory of the 3D pointing device corresponding to at least one of an absolute coordinate area and a relative coordinate area based on the received wireless signal and determining a position of the displayed object according to a property of an area to which the trajectory belongs and displaying the determined position, the property of the absolute coordinate area calculating the trajectory with respect to a predetermined absolute reference point and the property of the relative coordinate area calculating the trajectory based on relative positions of points forming the trajectory. The present invention provides a display device and a control method thereof, wherein if a 3D pointing device lies in the absolute coordinate area, a trajectory of the 3D pointing device is calculated with respect to the absolute reference point; and if the 3D pointing device is positioned in the relative coordinate area, a trajectory of the 3D pointing device is calculated with respect to a relative reference point.
