Patent ID: 7148860

Claim:
A self actuating head mounted display device, comprising: a supporting frame adapted to be worn on the head of a user and to thereby attach the head mounted display device to a head of a wearer; a display for generating an image, which display is operatively connected with the supporting frame; imaging optics for imaging the image via an eye of the wearer, which imaging optics are operatively connected with the supporting frame; and a display movement mechanism operatively connected between the supporting frame and the display whereby at least one angle of incidence at which the display is imaged via the eye is changed by the display movement mechanism; wherein the display movement mechanism includes a position detector that measures information about a position of the supporting frame, an actuator that changes the angle of incidence at which the display is imaged via the eye, and a controlling coupling operatively connected between the position detector and the actuator and arranged such that the display movement mechanism changes the angle of incidence relative to the supporting frame in accordance with changes in the position of the supporting frame, so that the angle of incidence of the image, moving along with the outside world, falls on the eye.
