Currently, 50 theaters in the US are running trials of D-Box’s shaking seats, which is more or less a more advanced version of force feedback whenever you play a video game – albeit your entire back and butt will be the ones experiencing all the rumbling.
Each seat comes with a trio of motors within, and when it is synchronized to a movie, any scenes that call for a vibration where necessary will do so, which means D-Box’s engineers have to go through all the movies associated with it frame-by-frame for a tailored experience. Now that’s dedication, and the Fast and the Furious 5 alone took a whopping 600 hours to program. Just how much more are you willing to pay for a 4D experience in the cinema?
