Abstract

Disclosed herein are systems and methods for controlling a computing environment with one or more gestures by sizing a virtual screen centered on a user, and by adapting the response of the computing environment to gestures made by a user and modes of use exhibited by a user. The virtual screen may be sized using depth, aspects of the user such as height and/or user profile information such as age and ability. Modes of use by a user may also be considered in determining the size of the virtual screen and the control of the system, the modes being based on profile information and/or information from a capture device.

Claims

1. A method for projecting a virtual screen, the method comprising:

detecting a person in an area;

determining distance from the person to a detector;

determining body information of the person;

determining, based on the distance and the body information, at least one of a size, shape or location of the virtual screen;

providing the virtual screen according to the at least one of size, shape or location; and

determining motions of the person within the virtual screen.

2. The method of claim 1 further comprising adjusting an audiovisual display based on at least one of the body information, or distance.

3. The method of claim 1 wherein the distance is measured using a depth camera.

4. The method of claim 1 wherein the size and shape of the virtual screen is determined based on additional information obtained from a lookup table.

5. The method of claim 1 wherein determining the at least one of size, shape, or location of the virtual screen further comprises identifying a profile associated with the person, wherein the profile comprises at least one of stored information about the person including size or facial recognition or voice recognition, or any combination thereof.

6. The method of claim 5 wherein information stored in the profile further comprises at least one of one or more aspects of the person'"'"'s playing history, age, or the person'"'"'s typical mode of play.

7. The method of claim 5 wherein an audiovisual display is adjusted according to stored profile information of the person.

8. The method of claim 1 wherein the virtual screen is centered on, and has dimensions corresponding to at least one of the person, an appendage of the person, or an object associated with the person.

9. The method of claim 1 wherein determining motions by the person is performed based on a precision of the person'"'"'s motions.

10. The method of claim 2 wherein a cursor on the audiovisual display tracks the person'"'"'s motions, and wherein the tracking by the cursor is adjusted according to at least one of the person'"'"'s playing history, typical mode of play, or profile information.

11. A computer readable medium having stored thereon computer executable instructions for projecting a virtual, comprising:

detecting a person in an area;

determining distance from the person to a detector;

determining body information of the person;

determining, based on the distance and the body information, at least one of a size, shape or location of the virtual screen;

providing the virtual screen according to the size and the location; and

determining motions of the person within the virtual screen.

12. The computer readable medium of claim 11 wherein the instructions further comprise adjusting an audiovisual display or a cursor or both based on at least one of the body information, or distance.

13. The computer readable medium of claim 11 wherein body information comprises at least one of height, or arm length.

14. The computer readable medium of claim 11 wherein determining the at least one of size, shape or location of the virtual screen comprises determining a portion of the person to center the screen on, and identifying a profile associated with the person, wherein the profile comprises stored information about the person including size or facial recognition or voice recognition, or any combination thereof, wherein virtual screen is centered on and has dimensions corresponding to at least one of the person, an appendage of the person or an object associated with the person.

15. The computer readable medium of claim 14 wherein the instructions further comprise adjusting an audiovisual display according to stored profile information of the person.

16. A system for projecting a virtual screen, the system comprising:

a detector for detecting a person in an area, determining distance from the person to the detector, determining body information of the person and determining motions of the person within the area; and

a computing device for determining, based on the distance and the body information, at least one of a size, shape or location of the virtual screen.

17. The system of claim 16 wherein the detector comprises a depth camera.

18. The system of claim 16 wherein the computing device comprises a game console.

19. The system of claim 16 wherein the computing device determines the at least one of size, shape or location of the virtual screen by identifying a profile associated with the person, wherein the profile comprises stored information about the person including size or age, or facial recognition or voice recognition, or any combination thereof.

20. The system of claim 16 wherein the virtual screen has dimensions corresponding to at least one of the person, an appendage of the person or an object associated with the person.
