Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

[ EN ]

What is claimed is:

A system for co-locating visual images and associated sounds, the system comprising:

(a) a screen for displaying the visual images, the screen having a

display surface upon which the visual images appear at corresponding areas of the display surface, the visual images having associated therewith apparent locations of the visual images, respectively, the apparent locations being selected from the group consisting of: corresponding zones defined within an immersive environment surrounding the screen, and the corresponding areas of the display surface; and

(b) a plurality of sound exciters for producing the associated sounds so as to render a location effect of the associated sounds originating from the apparent locations of the visual images, respectively.

The system of claim 1 wherein the apparent locations are selected as the corresponding zones, the plurality of sound exciters forming one or more sound walls distal from the screen.

The system of claim 2 wherein the plurality of sound exciters are operable to receive a spatially distributed audio signal of the associated sounds, the spatially distributed audio signal comprising location representations of a plurality of sets of three-dimensional coordinates identifying the

corresponding zones.

The system of claim 3 wherein the spatially distributed audio signal

comprises, in association with the location representations, associated representations for rendering the location effect, the associated

representations representing at least one of an audio volume, a

reverberation, an echo, and a spectral filtering.

5. The system of claim 4 further comprising a processor, and further

comprising a memory for storing computer-executable instructions for directing the processor to generate the spatially distributed audio signal.

6. The system of claim 1 wherein the apparent locations are selected as the corresponding areas of the display surface, and wherein the location effect is rendered by the sound exciters being operable to vibrate the display surface such that the associated sounds emit from the corresponding areas of the display surface, respectively.

7. The system of claim 6 wherein the plurality of sound exciters are operable to receive a spatially distributed audio signal of the associated sounds, the spatially distributed audio signal comprising two-dimensional location representations of a plurality of sets of two-dimensional coordinates identifying the corresponding areas.

8. The system of claim 7 further comprising a processor, and further

comprising a memory for storing computer-executable instructions for directing the processor to generate the spatially distributed audio signal.

9. The system of claim 6 wherein the screen is a video screen.

10. The system of claim 6 wherein the screen is a projection screen.

1 1 . A method of co-locating visual images and associated sound, the method comprising:

(a) displaying the visual images on a display surface of a screen at corresponding areas of the display surface when the visual images have associated therewith apparent locations of the visual images, respectively, upon selection of the apparent locations from the group consisting of: corresponding zones defined within an immersive environment surrounding the screen, and the corresponding areas of the display surface; and

(b) producing by a plurality of sound exciters the associated sounds so as to render a location effect of the associated sounds originating from the apparent locations of the visual images, respectively.

12. The method of claim 1 1 wherein step (a) comprises selecting the apparent locations as the corresponding zones, and step (b) comprises producing the associated sounds by the plurality of sound exciters forming one or more sound walls.

13. The method of claim 12 wherein producing the associated sounds by the plurality of sound exciters forming one or more sound walls comprises receiving by the plurality of sound exciters a spatially distributed audio signal of the associated sounds when the spatially distributed audio signal comprises location representations of a plurality of sets of three- dimensional coordinates identifying the corresponding zones.

14. The method of claim 13 wherein receiving by the plurality of sound

exciters the spatially distributed audio signal of the associated sounds when the spatially distributed audio signal comprises the location representations of the plurality of sets of the three-dimensional

coordinates identifying the corresponding zones comprises: receiving the spatially distributed audio signal comprising, in association with the location representations, associated representations for rendering the location effect when the associated representations represent at least one of an audio volume, a reverberation, an echo, and a spectral filtering.

15. The method of claim 14 further comprising directing a processor by

computer-executable instructions stored in a memory to generate the spatially distributed audio signal.

16. The method of claim 1 1 wherein step (a) comprises selecting the apparent locations as the corresponding areas, and wherein step (b) comprises rendering the location effect by the plurality of sound exciters vibrating the display surface at said corresponding areas so as to emit the associated sounds from said corresponding areas, respectively.

17. The method of claim 16 wherein rendering the location effect by the

plurality of sound exciters vibrating the display surface at said

corresponding areas so as to emit the associated sounds from said corresponding areas, respectively, comprises: receiving by the plurality of sound exciters a spatially distributed audio signal of the associated sounds when the spatially distributed audio signal comprises location representations of a plurality of sets of two-dimensional coordinates identifying the corresponding areas.

18. The method of claim 17 further comprising directing a processor by

computer-executable instructions stored in a memory to generate the

spatially distributed audio signal.

19. The method of claim 16 wherein step (a) comprises displaying the visual images on the display surface of a video screen.

20. The method of claim 16 wherein step (a) comprises displaying the visual images on the display surface of a projection screen.

21 . A system for co-locating visual images and associated sound, the system comprising:

(a) display means for displaying the visual images at corresponding areas of a display surface when the visual images have associated therewith apparent locations of the visual images, respectively, upon selection of the apparent locations from the group consisting of: corresponding zones defined within an immersive environment surrounding the display means, and the corresponding areas of the display surface; and

(b) audio means for producing the associated sounds so as to render a location effect of the associated sounds originating from the apparent locations of the visual images, respectively.

22. The system of claim 21 further comprising:

(c) processing means for generating a spatially distributed audio signal of the associated sounds such that the spatially distributed audio signal comprises representations of coordinates identifying the apparent locations.
