INPUT SYSTEM

摘要

Provided is an input system that is equipped with a completely flat coordinates input apparatus and a light-emitting pen, and wherein no mis-recognition will happen even if a hand or the like comes in proximity or in contact with the surface of the apparatus. An input system (50) of an embodiment of the present invention is provided with a pen input apparatus (40) and a pen (3) that emits light, and the pen input apparatus (40) comprises: a transparent light-guiding plate (1) onto the surface of which the pen (3) can come in contact, and that can couple the light of the pen (3) so as to be propagated therewithin; and image pickup units (10, 20) that pick up portions of luminous flux propagating within the transparent light-guiding plate (1), at mutually different locations. The contact coordinate-position of the pen (3) is obtained on the basis of the images captured by each of the image pickup units.
