FIELD: measurement equipment.SUBSTANCE: invention relates to equipment of optic-electronic measurement systems and devices of information input into calculation devices and systems. The device comprises optically coupled first and second emitters, "surface of shadow location", a television camera and a calculation device, besides, the emitters generate light beams with different spectral maxima ?and ?, and the television camera has appropriate separate spectral channels for reception of these emissions, at the same time coordinates of half-shadows generated from a finger of a man operator located on the way of these light beams, are input into the calculation device, which by their values calculates its spatial position.EFFECT: increased efficiency of a device.2 cl, 4 dwg |
