4DX

4DX is a motion picture technology owned and developed by South Korean company CJ 4DPLEX, a part of the CJ Group. 4DX allows a motion picture presentation to be augmented with environmental effects such as seat motion, wind, rain, fog, lights, and scents along with the standard video and audio. As such, theaters must be specially designed for and equipped with 4DX technology. The experience was introduced commercially in 2009 with the release of Journey to the Center of the Earth in Seoul, South Korea.
