Abstract

A head mounted display for a user that uses a display screen to produce images. The head mounted display includes a frame. The frame has a pair of lenses. The pair of lenses has their optical centers biased away from their physical centers. The head mounted display includes a strap which attaches to the frame and fits about the user'"'"'s head to hold the frame to the user'"'"'s head. A method for viewing images by a user.

Claims

1. A head mounted display for a user that uses a display screen to produce images comprising:

a frame having a first face which holds the display screen, a second face which holds a first reflecting surface;

a third face which holds a pair of lenses;

a fourth face which holds a second reflecting surface and a fifth face having two eyeholes and a nose hole that is positioned on the nose of the user, with the eyeholes aligned with the eye of the user, the light emitted from the display screen is reflected by the first reflecting surface to the pair of lenses, which focuses the light as it passes through the lenses to the second reflecting surface, which reflects the focused light to the eyes of the user through the eyeholes, the pair of lenses have their optical centers biased away from their physical centers; and

a strap which attaches to the frame and fits about the user'"'"'s head to hold the frame to the user'"'"'s head.

12. The head mounted display of claim 1 wherein the first face is disposed above the fifth face and is coplanar with the fifth face.

13. The head mounted display of claim 12 wherein the frame is made of cardboard.

14. The head mounted display of claim 13 wherein the frame can fold up.

2. A head mounted display for a user that uses a display screen to produce images comprising:

a frame having a first face which holds the display screen, a second face which holds a first reflecting surface;

a third face which holds a pair of lenses;

a fourth face which holds a second reflecting surface and a fifth face having two eyeholes and a nose hole that is positioned on the nose of the user, with the eyeholes aligned with the eye of the user, the light emitted from the display screen is reflected by the first reflecting surface to the pair of lenses, which focuses the light as it passes through the lenses to the second reflecting surface, which reflects the focused light to the eyes of the user through the eyeholes, the pair of lenses always maintain for any field of view two separate non-overlapping images for the user'"'"'s eyes; and

a strap which attaches to the frame and fits about the user'"'"'s head to hold the frame to the user'"'"'s head.

3. A method for viewing images by a user comprising the steps of:

placing a head mounted display on a head of the user, the head mounted display having a frame having a first face which holds a display screen, a second face which holds a first reflecting surface;

a third face which holds a pair of lenses;

a fourth face which holds a second reflecting surface and a fifth face having two eyeholes and a nose hole that is positioned on the nose of the user, with the eyeholes aligned with the eye of the user, the head mounted display having a strap which attaches to the frame and fits about the user'"'"'s head to hold the frame to the user'"'"'s head; and

emitting light from the display screen which is reflected by the first reflecting surface to the pair of lenses, which focuses the light as it passes through the lenses to the second reflecting surface, which reflects the focused light to the eyes of the user through the eyeholes, the pair of lenses always maintains for any field of view two separate non-overlapping images for the user'"'"'s eyes.

4. A method for viewing images by a user comprising the steps of:

placing a head mounted display on a head of the user, the head mounted display having a frame having a first face which holds a display screen, a second face which holds a first reflecting surface;

a third face which holds a pair of lenses;

a fourth face which holds a second reflecting surface and a fifth face having two eyeholes and a nose hole that is positioned on the nose of the user, with the eyeholes aligned with the eye of the user, the head mounted display having a strap which attaches to the frame and fits about the user'"'"'s head to hold the frame to the user'"'"'s head; and

emitting light from the display screen which is reflected by the first reflecting surface to the pair of lenses, which focuses the light as it passes through the lenses to the second reflecting surface, which reflects the focused light to the eyes of the user through the eyeholes, the pair of lenses have their optical centers biased away from their physical centers.

5. A head mounted display for a user that uses a display screen to produce images comprising:

a frame having a first face which holds the display screen, a second face which holds a first reflecting surface;

a third face which holds a pair of lenses;

a fourth face which holds a second reflecting surface and a fifth face having two eyeholes and a nose hole that is positioned on the nose of the user, with the eyeholes aligned with the eye of the user, the light emitted from the display screen is reflected by the first reflecting surface to the pair of lenses, which focuses the light as it passes through the lenses to the second reflecting surface, which reflects the focused light to the eyes of the user through the eyeholes, the pair of lenses have their optical centers biased away from their physical centers where the first, second, fourth and fifth faces form a parallelogram; and

a strap which attaches to the frame and fits about the user'"'"'s head to hold the frame to the user'"'"'s head.

6. The head mounted display of claim 5 including left and right sides which are opaque walls to block extraneous light from entering the HMD through the sides.

7. The head mounted display of claim 6 wherein each shape has a rectangular shape.

8. The head mounted display of claim 7 wherein the first face has a slot in which the display screen is disposed.

9. The head mounted display of claim 8 wherein the first face is in space relation with the fifth face and disposed above the third face with the fifth face dispose below the third face.

10. The head mounted display of claim 9 wherein the frame is made of cardboard.
