Abstract

A display system that detects the point of touch and three-dimensional direction of a pressure exerted by an object on a surface to select a corresponding spot on a real object. The system is comprised of a touching cube, a plurality of sensors attached to the touching cube, a microprocessor that receives the output of the plurality of sensors, a database, and a presentation unit that highlights a spot on the real object corresponding to the point of touch and three-dimensional direction.

Claims

1. A display system that detects the point of touch and three-dimensional direction of a pressure 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 and the real object can be seen through the transparent surface;

a plurality of sensors wherein at least one sensor of the plurality of sensors is in touch with one face of the six faces to detect the value of the force exerted on the one face due to the pressure;

a microprocessor that receives the output of the plurality of sensors 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 object; and

a presentation unit that manipulates a camera to rotate horizontally or vertically according to the three-dimensional direction wherein the camera is a camera of a head mounted computer display and the surface is a surface of the head mounted computer display highlighting a spot on the real object corresponding to the point of touch and three-dimensional direction.

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

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

4. The display system of claim 1 wherein the touching cube is a display of an electronic device such as a mobile phone, tablet, digital camera, or head-mounted computer display.

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

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

7. The display system of claim 1 wherein the plurality of sensors is a plurality of force sensors.

8. The display system of claim 1 wherein the database stores the three-dimensional model of the real object divided into a plurality of spots.

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

10. The display system of claim 1 further the presentation unit manipulates the spot to move.

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 pressure, and a second angle located between the projection of the line on the face plane and the x-axis of the face plane.

12. The display system of claim 1 wherein the object is a hand finger.

13. The display system of claim 1 wherein the object is two or more hand fingers simultaneously applying the pressure.

14. The display system of claim 1 wherein the real object is located outside the touching cube.

15. The display system of claim 1 wherein the camera is a camera of an electronic device such as a mobile phone or tablet.

16. The display system of claim 1 wherein the camera is a virtual camera of a computer and the real object is a virtual object presented on the computer display.

17. The display system of claim 1 wherein the camera is a depth sensing camera that detects the distance between the camera and the exterior points of the real object.

18. The display system of claim 1 wherein each unique value of the pressure represents a different zoom of the camera.
