perception

 [per-sep´shun]
the conscious mental registration of a sensory stimulus. adj., adj percep´tive.
depth perception the ability to recognize depth or the relative distances to different objects in space.
disturbed sensory perception a nursing diagnosis accepted by the North American Nursing Diagnosis Association, defined as a change in the amount of patterning of incoming stimuli, accompanied by a diminished, exaggerated, distorted, or impaired response to such stimuli.
extrasensory perception (ESP) knowledge of, or response to, an external thought or objective event not achieved as the result of stimulation of the sense organs.

Although human perceptual responses to binocular disparity have been studied extensively [14], there have been relatively few studies of how human cortical activity is related to stereo depth perception. In these few studies [15-17], the authors relied on measurements of visually evoked potentials, a method that has a limited spatial resolution.
We definitively demonstrated 3D vision or stereopsis in mantises and also showed that this technique can be effectively used to deliver virtual 3D stimuli to insects." The Newcastle team will now continue the research examining the algorithms used for depth perception in insects to better understand how human vision evolved and to develop new ways of adding 3D technology to computers and robots.
Two groups (experimental and control) performed a pre and post--training designed intervention in which Eye-hand coordination (EHC), Eye-foot coordination (EFC), visual acuity (VA), Visual memory (VM), Visual Tracking (VT), visual reaction time (VRT), Depth perception (DP) from different distances (10cm, 20cm and 30cm), Visual field (VF) and Performance level of shooting skill (3PS) were recorded.
Visitors to www.arinscooptics.com can take a simple vision test to determine if C3D will truly enhance their viewing experience, based on their existing depth perception function.
The findings of a role for arm length may help to explain depth perception and the limits of its accuracy, Domini said.
There is a slight feeling that things are popping out of the display and depth perception especially when you are consuming 3D video content (the source was YouTube).
The federal agency stated that drivers begin to have difficulties with depth perception and visual functions at .05 BAC.
This is accomplished by restoring natural 3-D vision and depth perception when performing laparoscopic procedures and is independent of a surgeon's skill level.

Some deficiencies in the systems that are used commonly were: in non-digital tomography, the focus of the rotating axis fix point overlaps with a number of unwanted images, due to the inappropriate depth perception that ultimately causes obscurity;2,3 beam divergence at the time of cone-shaped radiation emission allows image distortion; incomplete elimination of unwanted images causes partial blurring of the wanted slice, which is called non-digital tomographic blurring and which compromises its diagnostic value;4-6 and, with the widening of rotating angulations, the blurring is increased, and the depth perception is not reasonable for confident diagnosis, and if the thickness of the tomographic slice is decreased, it causes blurring which is a deficiency of the tomographic system.
With this technology, the patients continue to experience the benefits of minimal invasive surgery, while the surgeon gains the critical depth perception he needs during the operation.
The idea of the experiment was to determine whether a man undergoing the rigors of weightlessness could maintain his depth perception. Astronaut Carpenter found that he could....
