Additional effect system and method for multi-projection

A non-transitory recording medium readable by an electronic device, in which a method for implementing an additional effect is record as a program, the method comprising:

• (a) causing multi-projection images to be projected on a plurality of projection surfaces installed in a single theater by a plurality of projection devices wherein the images projected on the plurality of projection surfaces are synchronized with each other;
• and
• (b) causing an additional effect other than the images to be implemented by a plurality of additional effect devices, wherein the additional effect includes wind, smell, temperature change, water jet, vibration, or bubbles, and
• wherein the plurality of additional effect devices provides the additional effect depending on the multi-projection images projected on the plurality of projection surfaces, and the plurality of additional effect devices selectively changes the direction of the additional effect,
• wherein when a specific event in one of the images occurs only on a specific projection surface among the plurality of projection surfaces, the plurality of additional effect devices is configured to implement the additional effect only in a direction that starts from the specific projection surface, and
• wherein the multi-projection images are corrected so as to offset a difference in brightness, color or material of the plurality of projection surfaces.

An additional effect method for multi-projection, the method comprising:

• projecting, by a plurality of projection devices, a plurality of images on a plurality of projection surfaces installed in a single theater wherein the images projected on the plurality of projection surfaces are synchronized with each other;
• implementing, by a plurality of additional effect devices, an additional effect other than the images wherein the additional effect includes wind, smell, temperature change, water jet, vibration, or bubbles;
• and
• controlling, by an additional effect management device, the additional effect depending on the images projected on the plurality of the projection surfaces,
• wherein a direction of the additional effect is selectively changed based on the images,
• wherein when a specific event in one of the images occurs only on a specific projection surface among the plurality of projection surfaces, the plurality of additional effect devices is configured to implement the additional effect only in a direction that starts from the specific projection surface, and
• wherein the images to be projected on the plurality of projection surfaces are corrected so as to offset a difference in brightness, color or material of the plurality of projection surfaces.
