What Is 4D FX? How It Combines Sight, Sound, and Sensation
4D FX refers to four-dimensional effects that pair what you’re seeing and hearing with additional stimuli. Take, for example, the traditional viewing experience. When you’re watching something on a TV, only two senses are engaged: visual and auditory. You see the picture on the TV and hear the sound coming from its speakers. 4D immersive environments go beyond that by engaging more senses, like touch and smell.
