A 3d projector system by itself can only get you so far.  For true virtual reality, a projection wall must have real-time tracking and rendering.  The human brain is adept at interpreting 3D objects and spaces in the real world; its extraordinary effort to do so is by and large an unconscious one.  As our eyes dart and glance, as we turn our heads, and as our vision processing contends with many other such movements, the world stays external, fixed and stable.

Our Virtual Reality systems cheat this ingrained perception by continually responding to the user’s head movement and in turn rendering the appropriately computed image.  This ongoing process takes place within milliseconds – well below the human threshold of perception.  It’s all a trick.  And when done with precision, the simulation appears to the user as does the real world: external, fixed, and stable. Traditional 3D content by comparison is ineffectual.  Its limited illusion on the brain is thus easily broken, because it has no responsive mechanism to user movement and only renders the correct view from a single point in space.

With WorldViz PPT optical-inertial head tracking, the rendered image stream responds geometrically to output an accurate and distortion-free perspective based on the user’s head movement. Using stereo glasses and hand tracking, you stand in front of the display wall and interact with virtual objects floating in front of you in 3D. The image can be composed of one or several smaller high-resolution images creating a display that maintains image fidelity even at very close viewing distances. This leads to a versatile environment allowing tailoring displayed information to different depths within the physical workspace. The WorldViz PPTWand or a haptic glove lets you use natural hand movement and gestures to touch and grab objects you see floating in space, or to trigger specific user tasks or system actions.
