Inner Disturbance was the first game built for my Digital Vertigo Game research work. It is more of a technology pilot to investigate how Galvanic Vestibular Stimulation (GVS) can be used within digital games, to create and emphasise "Vertigo".
In the game, one player wears a GVS system and is challenged to stand on one leg whilst the system triggers in oscillating patterns, rocking the player side to side. If a player places their foot on the floor they lose the round.
Players play a total of five rounds, which increase in difficulty each time as the intensity of the stimulation also increases.
More about the work has been reported in my OzChi 2016 publication.
