Abstract

A display system that enables selecting a real object located in front of a user is disclosed. The display system can be utilized in mobile phones, tablets, digital cameras, and HMDs. Also a method for physically manipulating a camera to be rotated horizontally or vertically towards a real object is disclosed. The camera can be a camera of a head mounted computer display in the form of eye glasses where touching the frame of the eye glasses controls the camera rotation.

Claims

1. A display system that detects the point of touch and three-dimensional direction of a force exerted by an object on a surface to select a corresponding spot on a real object, wherein the display system is comprised of;

a touching cube with six faces wherein each face of the six faces is a transparent surface wherein a real object can be seen through the transparent surface;

a sensing unit that detects the simultaneous movements of the touching cube relative to the x-axis, the y-axis, and the z-axis when a force is exerted by an object at a point of touch on the touching cube;

a microprocessor that receives the data of the simultaneous movements from the sensing unit to determine the point of touch and the three-dimensional direction;

a database that associates each point of touch and three-dimensional direction with a corresponding spot on the real objects; and

a presentation unit that highlights the spot of the real object that is corresponding to current point of touch and three-dimensional direction.

2. The display system of claim 1 wherein the real object is located inside the touching cube, or located outside the touching cube.

3. The display system of claim 1 wherein the touching cube is a flat panel that has a front side, a back side, and side edges.

4. The display system of claim 1 wherein the touching cube is a display of a mobile phone, tablet, digital camera, or electronic device.

5. The display system of claim 1 wherein the touching cube is a frame of an eye glasses that function as a head mounter computer display.

6. The display system of claim 1 wherein the touching cube is in other form than a cube.

7. The display system of claim 1 wherein the sensing unit is at least six force sensors, and at least one force sensor of the at least six force sensors is positioned on each face of the six faces.

8. The display system of claim 1 wherein the database stores the three-dimensional model of the real object.

9. The display system of claim 1, further the presentation unit projects a light on the spot.

10. The display system of claim 1, further the presentation unit moves the spot or moves a part of the spot.

11. The display system of claim 1 wherein the three-dimensional direction is represented by a first angle located between a face plane of the touching cube and a line representing the force, and a second angle located between the projection of the line on the face plane and the x-axis of the face plane.

12. A method for manipulating a camera to rotate horizontally or vertically towards a real object wherein the method comprising;

exerting a force by an object on a surface wherein the three-dimensional direction of the force represents an imaginary line connecting between a point of view and a real object;

detecting the three-dimensional direction of the force; and

rotating the camera horizontally or vertically according to three-dimensional direction to align the axial of the camera lens to the real object.

13. The method of claim 12 wherein the camera is a camera of a head mounted computer display, the surface is the frame of the head mounted computer display, and the object is a user'"'"'s finger.

14. The method of claim 12 wherein the camera is a mobile phone camera, tablet camera, digital camera, or handheld device camera.

15. The method of claim 12 wherein the detecting is achieved by a plurality of force sensors positioned to be in touch with the surface.

16. The method of claim 12 wherein the three-dimensional direction is represented by a first angle located between the surface plane and a line representing the force, and a second angle located between the projection of the line on the surface plane and the x-axis of the surface plane.

17. A method for manipulating a camera attached to a frame of an eye glasses towards a real object wherein the method comprising;

exerting a force by a finger on the frame wherein the direction of the force represents an imaginary line connecting between the center of one of the eye glasses and the real object;

detecting the three-dimensional direction of the force; and

rotating the camera horizontally or vertically according to three-dimensional direction to align the axial of the camera lens to the real object.

18. The method of claim 17 wherein the detecting is achieved by a plurality of force sensors positioned to be in touch with the frame.

19. The method of claim 17 wherein the camera is two or more cameras.

20. The method of claim 17 wherein the finger is more than one finger simultaneously exerting a force on the frame.
