Abstract

A motion capture environment includes at least one sensor-tracker for tracking a location of a tracked object within the motion capture environment and one or more computers collectively operable to generate a virtual reality environment including a virtual control panel having a virtual control that, when actuated, effects a predetermined result in the virtual reality environment; determine a virtual location of the tracked object within the virtual reality environment; and determine when the virtual location of the tracked object coincides with the location of the virtual control to actuate the virtual control. The motion capture environment further includes a display device for displaying the virtual reality environment to an actor within the motion capture environment.

Claims

1. A motion capture environment, comprising:

a physical framework that defines physical limits of a virtually-represented studio within the motion capture environment;

a plurality of tracker-sensors mounted to the physical framework for tracking a location of a tracked object within the motion capture environment, the plurality of tracker-sensors including first and second tracker-sensors mounted at opposing physical limits of the studio;

at least one tracker-sensor mounted to the tracked object;

one or more computers collectively operable to;

generate a virtual reality environment within the physical framework, the virtual reality environment including a virtual control panel, the virtual control panel having a virtual control that, when actuated by an actor within the virtual reality environment, effects a predetermined result in the motion capture environment, the virtual control panel being a virtual artifact in the virtual reality environment configured to operate the virtual reality environment from within the virtual reality environment, the virtual control panel being manipulated by the actor to input information into the motion capture environment to control physical and virtual artifacts, the virtual control panel being configured to permit an actor within the virtual reality environment to operate the motion capture environment without an external operator;

determine a virtual location of the tracked object within the virtual reality environment; and

determine when the virtual location of the tracked object coincides with the location of the virtual control to actuate the virtual control; and

a display device for displaying the virtual reality environment to the actor within the motion capture environment.

2. The motion capture environment, according to claim 1, wherein the one or more computers are collectively operable to provide information to the actor via the virtual control panel.

3. The motion capture environment, according to claim 2, wherein the information concerns a computer-generated simulation.

4. The motion capture environment, according to claim 2, wherein the information is textual.

5. The motion capture environment, according to claim 2, wherein the information is graphical.

6. The motion capture environment, according to claim 1, wherein the virtual control is a virtual button.

7. The motion capture environment, according to claim 1, wherein the virtual control is a virtual knob.

8. The motion capture environment, according to claim 1, wherein the virtual control is a virtual switch.

9. The motion capture environment, according to claim 1, wherein the one or more computers are collectively operable to generate a virtual ruler for measuring distances in the virtual reality environment.

10. The motion capture environment, according to claim 1, wherein the tracked object is attachable to the actor.

11. The motion capture environment, according to claim 1, wherein the tracked object is a portion of a glove.

12. A method for controlling a motion capture environment operable to generate a virtual reality environment by an actor in the virtual reality environment, the method comprising:

providing a physical framework that defines physical limits of a virtually-represented studio within the motion capture environment;

providing a plurality of tracker-sensors mounted to the physical framework for tracking a location of a tracked object within the motion capture environment, the plurality of tracker-sensors including first and second tracker-sensors mounted at opposing physical limits of the studio;

providing at least one tracker-sensor mounted to the tracked object;

generating a virtual reality within the physical framework, the virtual reality environment including a virtual control panel, the virtual control panel having a virtual control that, when actuated by the actor within the virtual reality environment, effects a predetermined result in the motion capture environment, the virtual control panel being a virtual artifact in the virtual reality environment configured to operate the virtual reality environment from within the virtual reality environment, the virtual control panel being manipulated by the actor to input information into the motion capture environment to control physical and virtual artifacts, the virtual control panel being configured to permit an actor within the virtual reality environment to operate the motion capture environment without an external operator;

displaying the virtual reality environment to the actor participating in the virtual reality environment;

determining a virtual location of a tracked object within the virtual reality environment; and

determining when the virtual location of the tracked object coincides with the location of the virtual control to actuate the virtual control.

13. The method, according to claim 12, further comprising:

providing information to the actor via the virtual control panel.

14. The method, according to claim 13, wherein the information concerns a computer-generated simulation.

15. The method, according to claim 13, wherein providing information to the actor is accomplished by providing textual information to the actor.

16. The method, according to claim 13, wherein providing information to the actor is accomplished by providing graphical information to the actor.

17. The method, according to claim 12, wherein the virtual control is a virtual button.

18. The method, according to claim 12, wherein the virtual control is a virtual knob.

19. The method, according to claim 12, wherein the virtual control is a virtual switch.

20. The method, according to claim 12, further comprising:

generating a virtual ruler for measuring distances in the virtual reality environment.

21. The method, according to claim 12, wherein determining the virtual location of the tracked object within the virtual reality environment is accomplished by tracking an object operably associated with the actor.

22. The method, according to claim 12, wherein the object operably associated with the actor is a portion of a glove.
