Abstract

A method for creating an interactive display in which users/players can form the projection screen. The method includes providing granular display material, such as a layer of sand in a container, and storing a guide image and a display image in memory of a control system. Then, a projector is first operated to project the guide image on an upper surface of the display material. After a sculpting period or in response to a user or operator provided trigger, the method includes second operating the projector to project the display image on the upper surface which has been sculpted by the user into a 3D projection surface or screen during the first operating step. The projected guide image may include an outline of an object, and the display image may include an image element that is mapped to the location of the outlined object.

Claims

1. A method for creating an interactive display experience using a layer of granular display material, comprising:

sequentially projecting images from a set of guide images upon an upper surface of the granular display material;

projecting display images mapped to the guide images upon the upper surface of the granular display material;

tracking a tool;

generating an image in response to the tracked tool; and

projecting the generated image onto the upper surface of the granular display material.

2. The method of claim 1, wherein the step of projecting the display images mapped to the guide images includes a controller operating a digital projector based on an interactive display script.

3. The method of claim 2, wherein the interactive display script comprises a time period associated with each of the guide images and the controller operates the projector to display each of the guide images for the associated time period.

4. The method of claim 1, wherein the guide images are projected onto a projection area on the upper surface of the granular display material and wherein the guide images and the display images are mapped to the size and shape of the projection area.

5. The method of claim 4, wherein the display images each contain image elements mapped in size and location relative to the projection area to sculptures defined within the guide images projected on the upper surface.

6. The method of claim 1, wherein the generated image is static.

7. The method of claim 6, wherein the generated image includes at least a portion that is animated.

8. The method of claim 1, further comprising tracking a topography of the upper surface of the granular display material and wherein the generating of the image is based on the tracked position and the tracked topography.

9. The method of claim 1, wherein the tool tracking further comprises tracking a position of the tool.

10. The method of claim 1, wherein the tool tracking further comprises tracking a position of the tool relative to the upper surface of the granular display material.

11. An interactive display method, comprising:

focusing an image on an upper surface of sculptable display material;

providing an interactive display script, a set of guide images, and a set of display images mapped to the guide images;

based on the interactive display script, sequentially projecting the guide images upon the upper surface and then projecting corresponding ones of the display images upon the upper surface of the sculptable display material; and

tracking a position of a tool relative to the upper surface;

generating an image in response to the tracked position; and

projecting the generated image onto the upper surface of the sculptable display material.

12. The method of claim 11, wherein the interactive display script comprises a time period associated with each of the guide images and the act of sequentially projecting the guide images comprises projecting each of the guide images for the associated time period.

13. The method of claim 11, further comprising mapping the guide images and the display images to a size and a shape of a projection area on the upper surface.

14. The method of claim 13, wherein the display images each contain image elements mapped in size and location relative to the projection area to sculptures defined within the guide images projected on the upper surface.

15. A method for providing an interactive display, comprising:

providing a volume of a particulate material with an exposed upper surface;

selectively controlling a projector to display at least one guide image upon the exposed upper surface during a first period of time and to display at least one display image upon the upper surface after the first period of time,

wherein the guide image includes an image providing a guide for sculpting the granular material into a 3D object and the display image includes a component mapped to a location of the 3D object, and

wherein the component of the display image is projected on a portion of the exposed upper surface being sculpted into the 3D object.

16. The method of claim 15, wherein the sculpting guide comprises at least an outline of the 3D object at a predefined location on the upper surface of the sand.

17. The method of claim 16, wherein the sculpting guide further comprises an additional outline of a material removal area defining a source location for a volume of the sand to form the 3D object within the outline of the 3D object in the sculpting guide.

18. The method of claim 15, wherein a plurality of the guide images are displayed using the projector during the first time period, each of the guide images including at least one outline of a 3D object, whereby step-by-step visual cues for forming a 3D projection surface are displayed on the upper surface of the sand.

19. The method of claim 15, wherein the projected guide image and the projected display image are sized and shaped based on a location of the projector and a size and shape of the upper surface to map to the upper surface.

20. The method of claim 15, wherein the display image comprises a static color image or an animated color image.

21. The method of claim 15, further including:

tracking a position of a tool relative to the exposed upper surface; and

generating the display image in response to the tracked position.

22. The method of claim 15, further including:

determining a topography of the upper surface; and

generating the display image to match the determined topography of the upper surface.

23. A method for creating an interactive display experience using a layer of granular display material, comprising:

sequentially projecting images from a set of guide images upon an upper surface of the granular display material;

projecting display images mapped to the guide images upon the upper surface of the granular display material;

tracking topography of the upper surface of the granular display material;

generating an image in response to the tracked topography; and

projecting the generated image onto the upper surface of the granular display material.
