Abstract

A system and method are disclosed for interacting with virtual objects in a virtual environment using an accessory such as a hand held object. The virtual object may be viewed using a display device. The display device and hand held object may cooperate to determine a scene map of the virtual environment, the display device and hand held object being registered in the scene map.

Claims

1. A system for presenting a virtual environment, the virtual environment being coextensive with a real-world space, the system comprising:

a display device at least in part assisting in the determination of a scene map including one or more virtual objects, the display device including a display unit for displaying a virtual object of the one or more virtual objects in the virtual environment; and

an accessory capable of being moved in the real-world space independently of the display device, the accessory registered within the same scene map as the display device.

2. The system of claim 1, wherein the accessory is a hand held device.

3. The system of claim 2, wherein the hand held device includes an inertial measurement unit for providing at least one of acceleration or velocity data of the hand held device as it is moved in the real-world space.

4. The system of claim 1, wherein the accessory includes an imaging device and a puck.

5. The system of claim 4, wherein the imaging device is a first imaging device, the display device including a second imaging device, the first and second imaging devices enabling registration of the display device and accessory in the same scene map.

6. The system of claim 4, wherein the puck includes an inertial measurement unit for providing at least one of acceleration or velocity data of the accessory as it is moved in the real-world space.

7. The system of claim 4, wherein the puck includes a cellular telephone.

8. A system for presenting a virtual environment, the virtual environment being coextensive with a real-world space, the system comprising:

a display device at least in part assisting in the determination of a scene map including one or more virtual objects, the display device including a display unit for displaying a virtual object of the one or more virtual objects in the virtual environment; and

an accessory registered within the same scene map as the display device, the accessory capable of interacting with the virtual object.

9. The system of claim 8, the accessory interacting with the virtual object by selecting the virtual object using a virtual ray displayed on the display device, the virtual ray displayed as extending from the accessory to the virtual object.

10. The system of claim 9, the virtual ray generated upon selection of a real or graphical control on an input pad of the accessory.

11. The system of claim 9, the accessory interacting with the selected virtual object by causing the virtual object to be displayed as:

moving closer to the accessory along the virtual ray, moving away from the accessory along the virtual ray, moving the up, down, left or right relative to the virtual ray, increasing or decreasing in size or rotating.

12. The system of claim 9, the accessory interacting with the selected virtual object by at least one of copying the virtual object, pasting a duplicate of the virtual object within the virtual environment, removing the virtual object from the virtual environment, altering a color, texture or shape of the virtual object, or animating the virtual object.

13. The system of claim 8, the accessory interacting with the virtual object by selecting the virtual object upon the accessory contacting a surface of the virtual object or being positioned within an interior of the virtual object.

14. The system of claim 13, the accessory interacting with the selected virtual object by displaying the virtual object as moving with the accessory and being released at a new location within the virtual environment.

15. The system of claim 8, the accessory interacting with the virtual object by displaying the virtual object as moving away from the accessory upon the accessory contacting a surface of the virtual object.

16. The system of claim 8, the accessory configured as a shooting device, the accessory interacting with the virtual object by aiming the accessory at the virtual object and shooting at the virtual object.

17. A method of direct interaction with virtual objects within a virtual environment, the virtual environment being coextensive with a real-world space, the method comprising:

(a) defining a scene map for the virtual environment, a position of a virtual object being defined within the scene map;

(b) displaying the virtual object via a display device, a position of the display device being registered within the scene map; and

(c) directly interacting with the virtual object displayed by the display device using a hand held device, a position of the hand held device being registered within the scene map.

18. The method of claim 17, wherein said step (a) of defining the scene map comprises the step of the display device and hand held object cooperating together to define the scene map and register the positions of the display device and hand held device within the scene map.

19. The method of claim 17, the display device including a first imaging device, and the hand held device including a second imaging device, wherein said step (a) of defining the scene map comprises the step of the first and second imaging devices identifying common points in the fields of view of the first and second imaging devices, the identification of common points enabling registration of the display device and hand held device in the same scene map.

20. The method of claim 17, said step (c) of directly interacting with the virtual object comprising one of:

selecting the virtual object using a virtual ray displayed by the display device as emanating from the hand held object, and manipulating the hand held object so that the display device displays the virtual ray as intersecting the virtual device, or

selecting the virtual object by positioning the hand held object in real-world space at which the virtual object is displayed.
