<p>In a method of detecting a touch position, light is emitted. A plurality of light beams derived from the emitted light is received. The light beams have different paths from each other. The light beams are partially reflected according to a touch. The touch position is detected based on an amount of light in the received light beams. According to the present invention, the touch positions of several touching elements may be individually detected.</p> |
