Abstract

An interactive environment image may be projected onto one or more surfaces, and interaction with the projected environment image may be detected within a three-dimensional space over the one or more surfaces. The interactive environment image may be a three dimensional image, or it may be two dimensional. An image is projected onto a surface to provide a visual representation of a virtual space including one or more of the virtual objects, which may be spatially positioned. User interaction with the projected visualized representation of the virtual space may be detected and, in response to user interaction, the projected visualized representation may be changed.

Claims

1. A method for projecting an interactive environment image on at least one surface, the method comprising:

projecting an environment image on a surface, the environment image comprising a visualized representation of at least part of a virtual environment space, the visualized representation including a visualized representation of a plurality of virtual objects; and

detecting user interaction with the surface onto which the visualized representation is projected, including;

scanning a three-dimensional space over the surface onto which the visual representation is projected; and

detecting a contact between a manipulating element and a location on the surface corresponding to a virtual object of the plurality of virtual objects.

2. The method of claim 1, wherein detecting the user interaction comprises detecting a physical movement or manipulation of a physical object within the three-dimensional space.

3. The method of claim 1, wherein detecting user interaction with the surface onto which the visualized representation is projected further includes:

detecting extension of the manipulating element into the three-dimensional space from a location outside of the three-dimensional space.

4. The method of claim 3, wherein detecting user interaction comprises distinguishing between a plurality of elements simultaneously extending into the three-dimensional space from locations outside of the three-dimensional space.

5. The method of claim 1, further comprising:

changing the visualized representation in response to interaction between the manipulating element and the surface onto which the visualized representation is projected.

6. The method of claim 5, wherein changing the visualized representation comprises affecting the visualized object with which the manipulating element has interacted.

7. The method of claim 6, wherein affecting the visualized object comprises moving, manipulating or changing the visualized object.

8. The method of claim 5, wherein changing the visualized representation comprises adding a new visualized object to the visualized representation.

9. The method of claim 1, wherein projecting the environment image on the surface includes projecting at least a portion of the environment image on a substantially horizontal surface.

10. The method of claim 9, wherein projecting the environment image also includes projecting the environment image on a substantially vertical surface.

11. The method of claim 1, wherein projecting the environment image comprises projecting a prepared image tailored to a topography of the surface onto which the environment image is projected to ensure that features of the environment image a proportionately displayed on the surface.

12. The method of claim 1, wherein detecting user interaction with the surface includes detecting user interaction with a topography of the surface.

13. The method of claim 1, wherein the environment image includes three-dimensional information viewable by a user as a three-dimensional image.

14. The method of claim 1, wherein projecting the environment image on the surface comprises projecting a plurality of sub-images on the surface from a plurality of discrete locations, the method further comprising:

an act of formulating data representing the plurality of sub-images prior to projecting the plurality of sub-images.

15. A computing system, comprising:
