A projector is disposed at a position that is optically conjugated to a position of eyes of an observer. The projector projects an image to a screen that has retroreflection function so as to provide information of virtual space to the observer. If a real object such as a tactile sense provision device that is to be shielded by the virtual space exists, a part or the whole of the real object is optically hidden from the projection of the projector by a shielding member having retroreflection function, for example, by placing a shielding screen on which a retroreflection material is coated, or by coating the retroreflection material.

Method and device for providing information

A pair of projectors are arranged for projecting an image. These projectors are disposed in optically conjugate relationship with the observer's eyes respectively. An image of an object to be viewed by the observer is projected from the projectors and is allowed to appear on a screen, the shape of which corresponds to that of the object.
