Abstract

A head mounted display (HMD) including a display screen attached to a housing and aligned to be in a line of sight of a first eye of a user, an optics module disposed in the housing, for generating an image and projecting a beam of the image on the display screen, and a non-display screen attached to the housing and aligned to be in a line of sight of a second eye of the user, wherein the image displayed on the display screen is displayed at a virtual display distance different than a distance at which an image of the non-display screen is perceived.

Claims

1. A head mounted display (HMD) comprising:

a display screen attached to a housing and aligned to be in a line of sight of a first eye of a user;

an optics module disposed in said housing, for generating an image and projecting a beam of said image on said display screen; and

a non-display screen attached to said housing and aligned to be in a line of sight of a second eye of the user, wherein said image displayed on said display screen is displayed at a virtual display distance different than a distance at which an image of said non-display screen is perceived.

2. The HMD according to claim 1, wherein said display screen displays said image superimposed upon the image of said non-display screen.

3. The HMD according to claim 1, wherein said display screen and said non-display screen have similar light transmissivity.

4. The HMD according to claim 1, wherein said display screen and said non-display screen have similar light transmissivity and said display screen has a greater reflectivity than said non-display screen.

5. The HMD according to claim 1, wherein said non-display screen is darker than said display screen.

6. The HMD according to claim 1, wherein said non-display screen has similar optical reflectivity and transmission as said display screen.

7. The HMD according to claim 1, wherein said non-display screen has different optical reflectivity and transmission than said display screen.

8. The HMD according to claim 1, wherein a position of said beam with respect to said optics module to said display screen is adjustable so as to adjust said virtual distance at which said image is seen.

9. The HMD according to claim 1, wherein said optics module is movably mounted in said housing, such that a distance of said optics module to said display screen is adjustable.

10. The HMD according to claim 1, wherein said display screen is pivotally mounted to said housing by means of a hinge.

11. The HMD according to claim 1, further comprising a sensor in communication with said optics module, said sensor operative to sense movement of the user to provide the user with a feeling of objects moving across and off said display screen.

12. The HMD according to claim 11, wherein said sensor comprises a camera.

13. The HMD according to claim 1, further comprising sensors and controls to manipulate said image in communication with said optics module, said sensors operative to sense movement of the user to provide the user with a feeling of objects moving across and off said display screen.

14. The HMD according to claim 1, wherein said optics module creates random movements of images and audio devices create stereo sounds, thereby creating an effect of images floating around independently in surroundings without need for registration to the surroundings.
