Abstract : The purpose behind this thesis was to examine the effect of vibro-tactile feedback on a user 5 degree of immersion in a synthetic environment. Sub-woofers usually provide the vibro-tactile feedback in surround sound systems. The alternate method explored in this thesis utilized a seat shaker to generate the appropriate tactile feedback in the environment. The solution theoretically enables the user to receive a compelling, multi-modal presentation of the environment with deployable (small footprint), unobtrusive equipment. Physiological responses (electrodermal activity, heart rate, and temperature) were measured in an attempt to determine if there was a statistically significant difference between a user 5 degree of immersion and emotional response in a 5.2 surround sound environment versus one with stereo headphones and a seat shaker.
