Abstract

A display system and method for using the same are disclosed. In one embodiment, the display system comprises a swept volume display operable to produce a displayed swept volume and a re-imaging glass to re-image the displayed swept volume that appears on a first side of the re-imaging glass to a second side of the re-imaging glass.

First claim

I claim:

1. A display system comprising:
a swept volume display operable to produce a displayed swept volume, wherein the swept volume display comprises
a rotating structure having a plurality of petals, and
a projector to project light towards the rotating structure from beneath the plurality of petals, the rotating structure being operable to render the displayed swept volume by spinning the petals when light is being projected on the plurality of petals by the projector; and

a re-imaging glass to re-image the displayed swept volume that appears on a first side of the re-imaging glass to a second side of the re-imaging glass where a user is able to have direct interaction with the displayed swept volume, wherein the displayed swept volume is positioned at 45 degree angle behind and away from the reimaging glass and above a midpoint of the reimaging glass.

2. The display system defined in claim 1 wherein the rotating structure is operable to spin the petals at 45 degrees to render the displayed swept volume.

3. The display system defined in claim 1 wherein the plurality of petals comprises four petals.

4. The display system defined in claim 3 wherein the plurality of petals are configured to be at 45 degrees away from the viewer.

5. The display system defined in claim 1 further comprising a rotary encoder coupled to the plurality of petals.

6. The display system defined in claim 1 wherein the projector comprises a condenser lens and an integration rod.

7. The display system defined in claim 1 wherein the rotating structure causes a volume to sweep an area that is reimaged by the re-imaging glass at a correct angle to preserve light rays along an X axis and a Y axis, and wherein the re-imaged displayed swept volume appears at a first distance in front of the re-imaging glass equal to a second distance as a real volume is rendered on the petals.

8. The display system defined in claim 1 wherein the re-imaging glass comprises Asukanet glass.

9. A display system comprising:
a projector operable to project light;
a rotating structure having a plurality of petals operable to produce a volume display by spinning the petals when light is being projected on the plurality of petals by the projector from beneath the plurality of petals; and
a re-imaging glass to re-image the volume display that appears on a first side of the re-imaging glass to a second side of the re-imaging glass where a user is able to have direct interaction with the displayed swept volume, wherein the displayed swept volume is positioned at 45 degree angle behind and away from the reimaging glass and above a midpoint of the reimaging glass.

10. The display system defined in claim 9 wherein the rotating structure is operable to spin the petals at 45 degrees to render the volume display.

11. The display system defined in claim 9 wherein the plurality of petals comprises four petals.

12. The display system defined in claim 11 wherein the plurality of petals are configured to be at 45 degrees away from the viewer.

13. The display system defined in claim 9 further comprising a rotary encoder coupled to the plurality of petals.

14. The display system defined in claim 9 wherein the projector comprises a condenser lens and an integration rod.

15. The display system defined in claim 9 wherein the rotating structure causes a volume to sweep an area that is reimaged by the re-imaging glass at a correct angle to preserve light rays along an X axis and a Y axis, and wherein the re-imaged volume display appears at a first distance in front of the re-imaging glass equal to a second distance as a real volume is rendered on the petals.

16. The display system defined in claim 9 wherein the re-imaging glass comprises Asukanet glass.

17. The display system defined in claim 9 further comprising a 2D display touchscreen coupled to the volume display.

18. The display system defined in claim 9 wherein the volume display is a volumetric aerial image.

19. A method comprising:
creating a projected image volume using a swept volume display, wherein the swept volume display comprises
a rotating structure having a plurality of petals, and

a projector to project light towards the rotating structure from beneath the plurality of petals, the rotating structure being operable to render the displayed swept volume by spinning the petals when light is being projected on the plurality of petals by the projector; and
creating a re-imaged volume by reflecting the projected image volume from a first side of a re-imaging glass to a second side of the re-imaging glass where a user is able to have direct interaction with the displayed swept volume, wherein the displayed swept volume is positioned at 45 degree angle behind and away from the reimaging glass and above a midpoint of the reimaging glass.

20. The method defined in claim 19 further comprising:
rotating a plurality of petals; and
projecting light towards a rotating structure from beneath the plurality of petals, wherein the projected image volume is rendered by spinning the petals when light is being projected on the plurality of petals.

21. The method defined in claim 20 wherein the plurality of the petals are spun at 45 degrees to render the projected image volume.

22. The method defined in claim 20 wherein the plurality of petals are configured to be at 45 degrees away from the viewer.
