“Your vision will become clear only when you look into your heart. Who looks outside, dreams. Who looks inside, awakens.” – Carl Jung


Perhaps we will show Jung wrong when we develop technology that lets us look into ourselves by looking outward – W.O.M.B.


What qualities do our vision senses require for immersion?


There are 8 depth cues that deliver spatial information in what we see:

  1. Occlusion (hidden surfaces)
  2. Perspective Projection (parallel lines meet at infinity)
  3. Binocular Disparity  (each eye sees a different view)
  4. Motion Parallax (due to head motion)
  5. Convergence (rotation of the eyes to view a close object)
  6. Accommodation (change of shape of eye to view a close object - focus)
  7. Atmospheric (fog)
  8. Lighting and Shadows

All of the above can be accomplished with current technology with the exception of accommodation - VRD

Stereoscopic Vision

The majority of our spatial clues do not require binocular disparity, in fact we only use it to gauge distance when objects are within a few feet of us.

There are 2 major techniques for delivering different images to each eye:

Projection Based Techniques

Head Mounted Techniques

Both techniques have advantages and disadvantages:

What is the relationship to input?

The output of stereoscopic immersive display systems will only be as good as the tracking ability of the system.
