Hold on to your seat!
4D Cinema (or 4D Simulator/XD Cinema) is a 3D Cinema with added motion or other non-sight sensory stimulation. In addition to the standard 3D Cinema capabilities, the 4D Cinema offers the physical dimension to the experience, such as moving/vibrating seats, rain, strobe lights, wind and more. These additional tactile effects enrich the 3D Cinema making it a super sensory experience. 4D Cinema is ideal for theme parks, malls, and special events.
So what are the 6D, 7D, 8D and 9D Cinema models you keep hearing about? These model names are used to make the system sound more impressive but are simply a sum of all the sensory effects being used.
If you are looking for the most cutting edge experience, whether portable or stationary, 4D+ Cinemas (or XD Cinemas) are some of the best options in the market.
