Provided is an input device that may sense a first contact occurring along a planar coordinate axis among three-dimensional (3D) spatial coordinate axes to generate first contact information, to sense a second contact occurring along a vertical coordinate axis among the 3D spatial coordinate axes to generate second contact information, to analyze contact information including at least one of the first contact information and the second contact information to generate an input signal to control a predetermined display device, and to transmit the generated input signal to the display device. The display device may control an object that is displayed on the display device, based on the input signal. |
