<p>PURPOSE: An input device and an input method are provided to detect a connection according to a plane coordinate axis and connection according to a vertical coordinate axis from a three dimensional space coordinate axis and operating displayed object, thereby providing an intuitive interface to a user. CONSTITUTION: A contact sensing unit(111) generates first connection information by sensing a first connection along a plane coordinate axis from a three-dimensional space coordinate axis. A second connection sensing unit generates second connection information by sensing a second connection along a vertical coordinate axis from the three-dimensional space coordinate. An input signal generator(113) generates an input signal to a display device by analyzing at least one connection information segment between the first connection information and the second connection information.</p>
