Abstract

A system for the color coding of objects in the field of view of a plurality of spectacle wearers includes a pair of spectacles per spectacle wearer. Liquid crystal cells of at least one spectacle lens of the spectacles are so designed that a transmission of the liquid crystal cells may be switched between high and low transmission states. The system also includes one RGB light source per spectacle wearer and means for controlling or regulating the luminance times, color and intensity of the RGB light source such that the light source for a first spectacle wearer illuminates with a first color at a time of the state of high transmission of the liquid crystal cell and the light source for a second spectacle wearer illuminates at a time of high transmission of the liquid crystal cell of their spectacles with a second color different from the first.

Claims5

Dependent claims

System for enhancing the spatial impression of an object, comprising:

spectacles for a wearer with at least two eyes, a right and a left eye, with
one spectacle lens in front of each of the two eyes;
wherein each spectacle lens comprises a liquid crystal cell, the transmission of which may be varied by a suitable control;
wherein the liquid crystal cell is so designed that the transmission of the liquid crystal cells may be switched between high and low transmission states, respectively;
and with
means for controlling or regulating the times of the high transmission states of the liquid crystal cells;
and
with two light sources each associated with one eye;
wherein the two light sources emit different colors, and
wherein the stereoscopic base of the light sources is greater than the eye distance;
and
with means for controlling or regulating the lighting times of the light sources in such a way that the light source associated with the right eye illuminates during a high transmission state of the liquid crystal cell of the right eye, while the light source associated with the left eye does not illuminate, and the liquid crystal of the left eye is set to low transmission;
and vice versa.
