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.
Relative motion parallax
and target localisation in the locust, Schistocerca gregaria.
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.
In the last instance, the illusion of depth must depend on the use of 2-D cues such as occlusion, relative height, shading, linear perspective, texture gradient, and motion parallax
Actualdepth monitors overcome many of the eye fatigue issues resulting from poor convergence, motion parallax
, moire patterns, and restrictive viewing angles common to non-volumetric 3-D displays.
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 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.
