While existing diving simulators mostly focus on visual and aural displays, Amphibian simulates a wider variety of sensations experienced underwater. Users rest their torso on a motion platform to feel buoyancy. Their outstretched arms and legs are placed in a suspended harness to simulate drag as they swim. An Oculus Rift head-mounted display (HMD) and a pair of headphones delineate the visual and auditory ocean scene. Additional senses simulated in Amphibian are breath motion, temperature changes, and tactile feedback through various sensors. Twelve experienced divers compared Amphibian to real-life scuba diving.
