Abstract

A virtual touch screen system that helps interacting with a computer application on the computer display wherein said virtual touch screen system is comprised of a touchpad connected to the computer and detects the finger position on its surface to provide the computer system with an immediate input representing said finger position; a virtual touch screen which is a small window that appears on the computer display presenting a graphical user interface that enables interacting with said computer application; and a virtual spot which is a small circle that appears on said virtual touch screen representing the position of the finger on said touchpad wherein moving the finger on said touchpad manipulates said virtual spot to move on said virtual touch screen to interact with said graphical user interface.

Claims

1. A virtual touch screen system that helps interacting with a computer application on the computer display wherein said virtual touch screen system is comprised of a touchpad connected to the computer and detects the finger position on its surface to provide the computer system with an immediate input representing said finger position;

a virtual touch screen which is a small window that appears on the computer display presenting a graphical user interface that enables interacting with said computer application; and

a virtual spot which is a small circle that appears on said virtual touch screen representing the position of the finger on said touchpad wherein moving the finger on said touchpad manipulates said virtual spot to move on said virtual touch screen to interact with said graphical user interface.

2. The virtual touch screen system of claim 1 wherein said graphical user interface is comprised of a plurality of virtual objects such as menus, icons, keyboards, or the like.

3. The virtual touch screen system of claim 1 wherein said graphical user interface appears automatically on said virtual touch screen when said computer application is opened or becomes a current active application on the computer display.

4. The virtual touch screen system of claim 1 wherein said virtual touch screen can be shown or hidden on the computer display.

5. The virtual touch screen system of claim 1 wherein the locations, sizes, shapes, or the like of the virtual objects of said graphical user interface can be changed.

6. The virtual touch screen system of claim 1 wherein new icons, menus, keyboards, or the like can be added to said graphical user interface.

7. The virtual touch screen system of claim 1 wherein the position, shape, size, or the like of said virtual touch screen can be changed.

8. The virtual touch screen system of claim 1 wherein the size, shape, color, or the like of said virtual spot can be changed.

9. The virtual touch screen system of claim 1 wherein said touchpad detects the level of pressure of the finger on its surface whereas said level of pressure changes the size of said virtual spot.

10. The virtual touch screen system of claim 1 wherein a sticker is attached to said touchpad to mimic the sensory feeling of touching the objects of said graphical user interface by having the image of said objects printed and slightly raised from the surface level of said sticker.

11. The virtual touch screen system of claim 1 wherein said touchpad is a laptop touchpad, a mobile phone touchpad, or the like.

12. The virtual touch screen system of claim 1 wherein said computer application is a two-dimensional computer application or a three-dimensional computer application.

13. The virtual touch screen system of claim 1 wherein said computer is a mobile phone, a handheld device, or the like.

14. The virtual touch screen system of claim 1 wherein said graphical user interface is x, y, and z-axis whereas moving said virtual spot parallel to said x, y, or z-axis manipulates objects to respectively move along the x, y, and z-axis on the computer display, and moving said virtual spot perpendicular to said x, y, or z-axis manipulates objects to respectively rotate about the x, y, or z-axis on the computer display.

15. The virtual touch screen system of claim 2 wherein tapping on said touchpad when said virtual spot is overlapped with one of said plurality of objects provides the computer system with an input representing clicking on said one of said plurality of objects.

16. The virtual touch screen system of claim 3 wherein said graphical user interface is a plurality of graphical user interfaces that can be presented individually on said virtual touch screen.

17. The virtual touch screen system of claim 6 wherein said new icons, menus, keyboards, or the like are mapped to a keyboard shortcut, keystrokes, a mouse movement, or the like.
