Abstract

The present invention provides a multi-projection system and method including direction-changeable audience seats, and the multi-projection system includes a plurality of projection surfaces installed in a single theater; and an audience seat whose direction is changed depending on images projected on the plurality of projection surfaces.

Claims

1. A multi-projection system, comprising:

a plurality of projection surfaces installed in a single theater, the plurality of projection surfaces including a first projection surface and a second projection surface;

an audience seat configured to change a direction thereof; and

a seat control device configured to transmit a control signal to the audience seat to control the audience seat to change the direction depending on images projected on the plurality of projection surfaces,

wherein, the control signal includes

time information, which an operation of the audience seat is synchronized to, for controlling the audience seat depending on the images, and

operation information on an operation to be performed by the audience seat at a corresponding time,

wherein the operation information includes speed information,

wherein the audience seat is configured to change the direction of the audience seat at different speeds corresponding to the speed information, and

wherein, when an object in a first image projected on the first projection surface moves into a second image projected on the second projection surface, the seat control device is configured to control the audience seat to change the direction toward the second projection surface.

2. The multi-projection system of claim 1, wherein the audience seat is configured to change the direction by a rotational motion.

3. The multi-projection system of claim 2, wherein the audience seat is configured to perform the rotational motion about rotational axes that are present three-dimensionally.

4. The multi-projection system of claim 2, wherein the audience seat is configured to move, by a linear motion, toward or away from the second projection surface according to a movement of the object.

7. The multi-projection system of claim 1, further comprising:

an additional audience seat installed in the theater, and

the seat control device is configured to control the installed audience seats to change directions of the installed audience seats toward the second projection surface simultaneously.

8. The multi-projection system of claim 1, wherein the plurality of projection surfaces is arranged to surround the audience seat.

9. The multi-projection system of claim 1, wherein the images projected on the plurality of projection surfaces are parts of a synchronized image as a whole.

10. The multi-projection system of claim 1, wherein the audience seat comprises a user input unit configured to control the direction of the audience seat by a user.

11. The multi-projection system of claim 1, wherein the audience seat comprises an additional effect device configured to perform at least one of a vibration effect, a tickling effect, an air shot effect, and a water shot effect in synchronization with the images.

12. The multi-projection system of claim 1,

wherein the audience seat comprises an additional effect device configured to perform at least one effect of a vibration effect, a tickling effect, an air shot effect, and a water shot effect in synchronization with the images, and

wherein, when the object moves between the images projected on the plurality of the projection surfaces, the seat control device is configured to control the audience seat to perform the at least one effect associated with the object.

5. A multi-projection system, comprising:

a plurality of projection surfaces installed in a single theater;

an audience seat whose direction is changed depending on images projected on the plurality of projection surfaces; and

a seat control device configured to transmit a control signal to the audience seat to control the audience seat to change the direction depending on images projected on the plurality of projection surfaces,

wherein the control signal includes time information, which an operation of the audience seat is synchronized to, for controlling the audience seat depending on the images, and operation information on an operation to be performed by the audience seat at a corresponding time,

wherein the operation information includes speed information,

wherein the audience seat is configured to change the direction of the audience seat at different speeds corresponding to the speed information, and

wherein when a specific event occurs only in an image on a specific projection surface among the plurality of projection surfaces, the direction of the audience seat is changed toward the specific projection surface.

6. The multi-projection system of claim 5, wherein the audience seat is configured to move, by a linear motion, toward or away from the projection surface where the image is projected depending on a movement of the object.

13. The multi-projection system of claim 5,

wherein the audience seat comprises an additional effect device configured to perform at least one effect of a vibration effect, a tickling effect, an air shot effect, and a water shot effect in synchronization with the images, and

wherein the audience seat is configured to perform the at least one effect associated with the predetermined event.

14. A multi-projection method performed by a multi-projection system, the method comprising:

projecting multiple images on a plurality of projection surface installed in a single theater, respectively, the plurality of projection surfaces including a first projection surface and a second projection surface; and

changing a direction of the plurality of audience seats installed in the single theater depending on the projected images by transmitting a control signal to each of the audience seats,

wherein the control signal includes time information, which an operation of the audience seat is synchronized to, for controlling the audience seat depending on the images, and operation information on the operation to be performed by the audience seat at a corresponding time,

wherein the operation information includes speed information,

wherein the direction of the audience seat is changed at different speeds corresponding to the speed information, and

wherein, when an object in a first image projected on the first projection surface moves into a second image projected on the second projection surface, the direction of the plurality of audience seats is changed toward the second projection surface.
