Abstract: A method of reducing virtual reality simulation sickness is disclosed. The method starts with rendering a virtual world in a user's field of vision, then detecting and generating a signal indicating a desire to move. Upon detecting the desire to move, a SpiritMove process is conducted, including rendering a SpiritRoom that appears substantially stationary in the field of vision, adjusting a transparency level of the virtual world to appear transparent relative to the SpiritRoom, and simulating movement to the new location over a sequence of frames. During the SpiritMove process, the virtual world appears to move, while the SpiritRoom appears to remain substantially stationary.
