The fifth sense.
From the time movies first emerged as a pastime, filmmakers and theater owners have tried to come up with ways to make the movie experience more and more realistic. The picture (other than size) couldn't change, so they tried other ways. Some, like the Smellorama, didn't work. Others, like multichannel sound, did. Moving from one channel to six or eight channels, most people would think, "I'm surrounded by sound. What else is there?" What all, or at least most, systems lack is the ability to touch you—to literally touch you. Clark Synthesis' line of transducers aims to change that with tactile sound.
