Abstract

A multi-level visual display system has a plurality of screens spaced in the depth direction. A user can move a visual indicator such as a cursor between the screens, via an input device such as a mouse button. In drawing applications a visual link such as a line can be created between two screens. In game applications a user can move an image both within and between screens by dragging a cursor while moving it between the screens, to provide an illusion of three dimensional movement. The screens may comprise layered liquid crystal displays.

Claims

1. A system comprising:

a multi-component display comprising;

a first display screen comprising a first plurality of pixels, wherein said first display screen is configured to display a visual indicator using said first plurality of pixels; and

a second display screen comprising a second plurality of pixels, wherein said first and second display screens overlap, and wherein each of said first and second display screens is partially transparent; and

a user interface component comprising a user-selectable input component, wherein said user-selectable input component is configured to move said visual indicator from a first plane to a second plane in response to a first user interaction with said user-selectable input component, and wherein said first plane corresponds to said first display screen.

2. The system of claim 1, wherein said second plane corresponds to said second display screen.

3. The system of claim 1, wherein said user interface component is selected from a group consisting of a mouse, a keyboard, a joystick, and a tablet data glove.

4. The system of claim 1, wherein said user interface component is selected from a group consisting of a touchscreen and a touch pad.

5. The system of claim 1, wherein said user interface component is selected from a group consisting of a pen and a stylus.

6. The system of claim 1, wherein said user interface component is a voice-activated user interface component.

7. The system of claim 1, wherein said user-selectable input comprises a button of said user interface component.

8. The system of claim 1, wherein said user interface component is configured to move said visual indicator on said second plane in response to a second user interaction with said user interface component.

9. The system of claim 8, wherein said user interface component is further configured to move said visual indicator on said second plane after movement of said visual indicator from said first plane to said second plane.

10. The system of claim 1, wherein said visual indicator is selected from a group consisting of an icon, a cursor, an image and a screen image.

11. The system of claim 1, wherein said visual indicator is associated with an application selected from a group consisting of a gaming application, a drawing application and a graphical application.

12. The system of claim 1, wherein said first and second plurality of pixels overlap.

13. The system of claim 1, wherein said user-selectable input component is further configured to display an image between said visual indicator on said first plane and said visual indicator on said second plane.

14. A method of using a multi-component display, said method comprising:

displaying a visual indicator using a first plurality of pixels of a first display screen of said multi-component display, wherein said multi-component display further comprises a second display screen, wherein said first and second display screens overlap, wherein each of said first and second display screens is partially transparent, and wherein said second display screen comprises a second plurality of pixels;

detecting a first user interaction with a user interface component, wherein said user interface component comprises a user-selectable input component, and wherein said detecting further comprises detecting a first user interaction with said user-selectable input component; and

in response to said detecting a first user interaction, moving said visual indicator from a first plane to a second plane, wherein said first plane corresponds to said first display screen.

15. The method of claim 14, wherein said second plane corresponds to said second display screen.

16. The method of claim 14, wherein said user interface component is selected from a group consisting of a mouse, a keyboard, a joystick, and a tablet data glove.

17. The method of claim 14, wherein said user interface component is selected from a group consisting of a touchscreen and a touch pad.

18. The method of claim 14, wherein said user interface component is selected from a group consisting of a pen and a stylus.

19. The method of claim 14, wherein said user interface component is a voice-activated user interface component.

20. The method of claim 14, wherein said user-selectable input comprises a button of said user interface component.

21. The method of claim 14 further comprising:

in response to detecting a second user interaction with said user interface component, moving said visual indicator on said second plane.
