US Patent 7474277 Direct ocular virtual 3D workspace

A direct ocular virtual 3D workspace (laser-based 3D display system) utilizes traditional binocular methods of image composition to produce a 3D workspace in the observers' psyche. This direct ocular virtual 3D workspace is implemented such that in moving environments, such as on a ship or vehicle, the immersion of the individual into the display environment will not result in vertigo and/or motion sickness. This is resolved by utilizing a system that accomplishes eye-tracking, and produces the display image within the eye by means of laser projection. Two images can thus be projected into an individual's eyes to produce a 3D holographic-like image space. The individual will still maintain partial vision, resulting in a holographic-like display in space that the observer can look through. The images provided to multiple collaborators/users are geometrically corrected for each collaborator.
