Based on that information, the system quickly renders a pair of stereo images to simulate the effect of binocular vision and motion parallax. The resulting views are comfortable to look at--no headaches due to mixed visual messages, no eyestrain, no unfocused or otherwise illogical views.
"Motion parallax provides a greater sense of personal connection between users than other approaches, and we are able to create this effect without the need for expensive displays, multi-camera arrays or elaborate motion capture equipment, potentially making this technology available to nearly anyone with a handheld communication device," Brick said.
Additionally, in natural scenes small head or body movements provide depth information in terms of motion parallax. The virtual scenes we used lacked these depths cues as we presented them non-stereoscopically and without scene rendering according to the subject's head movement and orientation.
Our incredible ability to perceive depth through stereopsis, motion parallax, focus, and eye convergence is more reliable and useful than the visual cues present in current 2D displays using relative size, superposition, and lighting.
This computation has been under scrutiny for long, But there are still many unanswered questions about how different depth cues, Such as motion parallax and stereopsis, Are utilized, And about the neural mechanisms underlying depth perception.
This type of hologram epitomises the key characteristics of the medium: at their best they are true 3D images, re-creating or creating a volume of space and the objects or items in it, with full motion parallax and the ability to draw the viewer in to that space.
