DEVICE FOR ORGANISATION OF 3D USER INTERFACE Russian patent published in 2014 - IPC G09G5/00 

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 γ₁ and γ₂, 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.
