Virtual Jetski

What We Did

In designing and implementing VR systems the immersion of the user within the environment is perhaps the most difficult feature to achieve, and yet informally it is often the measure of success for such a system. We investigated the ability of multi-modal sensory cues to increase the immersion of the user. The resulting virtual reality system consists of a race car chair mounted to a Stewart Platform; which provides motion cues for the user, coupled with a tracked head mounted display (HMD), which provides visual stereo cues to the user. Tracking of the motion of the platform and the user’s head is used to provide a realistic user-driven rendering of the environment. A custom virtual visual and physical environment was created for the user to navigate through.

What We Found

The use of several different sensory inputs provides a method for distracting the user from any inconsistencies in any given medium, either visual or physical, by blending all the sensory inputs together and making the individual sensory inputs as consistent as possible. By providing multi-modal inputs to the user it is possible for a small deficiency of any one input to be compensated through the use of another input. When the inputs are balanced and blended correctly the immersion caused by the system as a whole is greater than the contributions of the individual inputs alone.
