THREE-DIMENSIONAL INFORMATION DISPLAYING DEVICE

摘要

Three-dimensional information is displayed without the use of a display device such as a display or a HUD, but displayed directly on a surface of a three-dimensional object provided as a subject from which the three-dimensional information originates. Two projectors (P1 and P2) emit spatially coded optical patterns to a surface of the object. Light beams emitted from the two projectors (P1 and P2) are combined together on the surface of the object into a beam having one color and one luminance level. Since the light beams are simply added up on the surface of the object, patterns of colors and brightness according to distances and heights are generated on the surface of the object, whereby a person is enabled to emphatically perceive information on a distance between the person and the object, as well as a three-dimensional shape of the object, due to colors and brightness on the object.
