It can bring the viewers strong incentive on visual, listening, touching or even smelling sensation, and bring an all-round feeling to all the sensory organs.
4D Motion Chair
4D motion chairs are the most important part in 4D and 5D cinemas. 4D motion chairs move according to the film story. The motion chairs contain some effects which are controlled by the computer. The main difference between 4D and 5D biograf is that there is only wind blowing and dynamic system in 4D-biograf while 5D cinema contains more abundant unique effects controlled by the computer such as falling, shaking, blowing, water spraying, rotating, yawing, pitching and rolling.
Therefore, the chairs can mobilize the perceptual system of the viewers and make them really come into the plots. This makes the viewers feel the scene closely and enjoy a completely new experience.
For the moment there are three kinds of motion chairs. They are pneumatic system, hydraulic power system and servo motor system. The pneumatic chairs are of the lowest price, but the quality is not good enough. Chairs of this kind are fit for the use of large cinemas. Comparatively, the price of hydraulic chairs is moderate, and the quality is also favorable. These chairs, whose life is one to three years, are widely used in normal cinemas. The servo motor chairs are the most expensive ones, and of course, they are of the best quality.
