• Wireless positional tracking
  • Body tracking
  • Haptics (Any form of interaction using touch)
  • Using physical props that are mapped to the virtual world, adds a sense of touch, which is missing from most VR experiences. Adds a whole new sense of immersion.
  • Real world environmental effects. In the Void, to make the people feel like there is empty air in front of them, if they take another step, there is one inch of space between the floor they are on and the floor in front, which is actually enough to make them believe when they reach their foot out.
  • Mapping physical environment to virtual environment. The physical is the real geometry while the virtual adds texture.
  • The less the player is aware of the controllers he is using, the more presence the world has.
