Performance system with multi-projection environment

1. A performance system comprising:

a stage installed for a performance;

a plurality of projection surfaces comprising a screen and a wall, arranged around the stage, and arranged unparallel to each other;

a plurality of projection devices configured to project images on the plurality of projection surfaces;

a management device configured to control the plurality of projection devices;

a position detection device configured to detect a position of an object or person placed on the stage; and

an additional effect device configured to perform an additional effect other than the images projected on the plurality of projection surfaces,

wherein the images projected on the plurality of projection surfaces are synchronized each other,

wherein the management device is configured to correct the synchronized images projected on the plurality of the projection surfaces based on relative differences in the at least brightness, color and reflectivity between the screen and the wall, and

wherein the additional effect device is configured to configure a direction of the additional effect differently depending on position information of the detected position of the object or the detected person.

2. The performance system of claim 1 , further comprising:

audience seats arranged toward the stage,

wherein the plurality of projection surfaces are arranged to surround the stage and the audience seats, and

wherein the synchronized images are projected on the plurality of projection surfaces, respectively.

3. The performance system of claim 1 , wherein the additional effect comprises wind, smell, fog, temperature change, laser, water, light, or bubbles.

4. The performance system of claim 1 , further comprising:

an imaging device configured to take an image of a person on the stage,

wherein the imaging device is configured to recognize movement of the person based on the image taken by the imaging device, and

wherein the additional effect device is configured to perform the additional effect based on the recognized movement.

5. The performance system of claim 1 , wherein, among the plurality of the projection surfaces, a specific image is reproduced on a projection surface closest to the detected position of the object.

6. The performance system of claim 1 , wherein the position detection device comprises a plurality of sensors distributed around the stage, and is configured to detect the position of the object using the plurality of the sensors.

7. The performance system of claim 1 , wherein the additional effect device is configured to change the direction of the additional effect depending on the synchronized images projected on the plurality of projection surfaces.

8. The performance system of claim 7 , wherein, when an object in the synchronized images moves between the projection surfaces, the additional effect device is configured to change the direction of the additional effect.

9. The performance system of claim 7 , wherein when a specific event in the synchronized images occurs only on a specific projection surface among the plurality of projection surfaces, the additional effect device is configured to perform the additional effect toward the specific projection surface only.

10. The performance system of claim 2 , further comprising:

a floor configured to detachably attach the audience seats.

11. The performance system of claim 10 , wherein the floor comprises an insertion groove for detachable attachment of at least one audience seat among the audience seats.

12. The performance system of claim 11 ,

wherein the floor comprises an insertion groove cover, and

wherein the insertion groove cover is configure to be removable so that the at least one audience seat is detachably attached to the floor surface at the insertion groove.

13. The performance system of claim 10 , wherein the floor is configured to perform a linear motion, rotational motion, height adjustment motion, tilting motion, or vibration motion.

14. A performance system comprising:

a stage installed for a performance;

a plurality of projection surfaces arranged around the stage and arranged unparallel to each other;

a position detection device configured to detect a position of an object or person placed on the stage; and

an additional effect device configured to perform an additional effect other than the images projected on the plurality of projection surfaces,

wherein the images projected on the plurality of projection surfaces are synchronized each other,

wherein the additional effect device is configured to configure a direction of the additional effect differently depending on position information of the detected position of the object or the detected person,

wherein the additional effect device is a light-emitting device, and

wherein the light-emitting device is configured to change a color of emitted light based on an image of a specific projection surface among the plurality of projection surfaces.
