Abstract

A surround visual field framework or system and methods are presented. In an embodiment, a surround visual field system comprises a control signal extractor that obtains a control signal that is related to the input stream. The control signal is provided to a coupling rule that links the control signal to an effect on an element of a surround visual field. The effect is applied to the element of the surround visual field thereby creating a surround visual field that has a characteristic or characteristics which relate to an input audio/visual stream presentation. In one embodiment, the surround visual field is displayed in an area partially surrounding or surrounding the input stream being displayed. In embodiments, the surround visual field may be a rendering of a three-dimensional environment. In embodiments, one or more otherwise idle display areas may be used to display a surround visual field.

Claims

1. A method for generating a surround visual field comprising a plurality of elements, the method comprising:

creating a coupling rule that receives a control signal as an input and outputs an effect on at least one element from the plurality of elements of the surround visual field;

obtaining the control signal that is related to an input stream;

applying an effect to the at least one element from the plurality of elements of the surround visual field based upon the control signal and the coupling rule; and

displaying the surround visual field in an area that surrounds or partially surrounds an area displaying the input stream.

2. The method of claim 1 wherein the at least one element is an articulate element.

3. The method of claim 2 wherein the coupling rule comprises a behavior model.

4. The method of claim 3 wherein the behavior model comprises a plurality of motion clips of the at least one element and wherein a transition between two of the plurality of motion clips of the at least one element is related to the control signal.

5. The method of claim 1 wherein the at least one element is a background element or a foreground element.

6. A computer-readable medium carrying one or more sequences of instructions which, when executed by one or more processors, cause the one or more processors to perform at least the steps of claim 1.

7. The method of claim 1 wherein the coupling rule is one selected from the group comprising:

a coupling rule associated with a local control signal and a growth coupling rule associated with a global control signal.

8. The method of claim 1 wherein the control signal is a local control signal and the method further comprises the steps of:

creating a growth coupling rule that receives a global control signal as an input and outputs an effect on a second at least one element from the plurality of elements of the surround visual field;

obtaining the global control signal that is related to the input stream; and

applying an effect to the second at least one element from the plurality of elements of the surround visual field based upon the global control signal and the growth model.

9. The method of claim 8 wherein the at least one element and the second at least one element are the same element.

10. The method of claim 8 wherein the global control signal is derived from one or more local control signals.

11. A computer-readable medium carrying one or more sequences of instructions which, when executed by one or more processors, cause the one or more processors to perform at least the steps of claim 1.

12. A surround visual field system for generating a surround visual field comprising a plurality of elements, wherein the surround visual field is displayed in an area surrounding or partially surrounding an input stream, the system comprising:

a control signal extractor that receives the input stream and obtains a control signal that is related to the input stream; and

a coupling rule that receives the control signal as an input and outputs an effect on at least one element from the plurality of elements of the surround visual field.

13. The system of claim 12 wherein the element is an articulated element.

14. The system of claim 13 wherein the coupling rule comprises a behavior model.

15. The system of claim 14 wherein the behavior model comprises a plurality of motion clips of the at least one element and wherein a transition between two of the plurality of motion clips of the at least one element is related to the control signal.

16. The system of claim 12 wherein the control signal extractor that receives the input stream obtains a local control signal that is related to the input stream and a global control signal that is related to the input stream, and wherein the system further comprises a growth coupling rule that receives the global control signal as an input and outputs an effect on a second at least one element from the plurality of elements of the surround visual field.

17. The system of claim 16 wherein the at least one element and the second at least one element are the same element.

18. The system of claim 12 further comprising a display device for displaying the surround visual field in an area that surrounds or partially surrounds an area displaying the input stream.

19. A method for generating a surround visual field that is responsive to an input stream, the method comprising:

obtaining a local control signal that is related to the input stream and a global control signal that is related to the input stream;

affecting a foreground or background element of the surround visual field based upon the local control signal and a coupling rule; and

affecting a foreground or background element of the surround visual field based upon a growth coupling rule and the global control signal.

20. The method of claim 19 further comprising the steps of:

displaying the input stream in a first area; and

displaying the surround visual field in a second area that at least partially surrounds the first area.
