A monocular cue to depth refers perception of motion that only relies on the perception of a single eye. Monocular cues include size: distant objects subtend smaller visual angles than near objects, grain, size, and motion parallax. However binocular cue to depth refers to perception of motion that relies on a two-eyes. Binocular cues include stereopsis, eye convergence, disparity, and yielding depth from binocular vision through exploitation of parallax. Binocular cues are important to the monocular cues due to the rise in depth they offer compared to the single eye monocular cues. Having two eyes increases an individual’s depth perception of close objects that are at two different distances.
My scientific concept is how sight effects balance. Balance is the equal distribution of weight. “Balance is controlled by the vestibular system, which includes the eyes, the inner ear, and other sensory systems of the body” (asha.org). The visual system interacts with the vestibular system by using the
Sensory signals relating information about our physical movements, as well as information regarding external object motion, are required in order to preserve a stable and accurate view of the world, and estimate external motion. Space constancy is the visual system’s ability to maintain a view of the outside world that does not jump about and move with an eye movement (Deubel, Bridgeman, & Schneider, 1998; Stark & Bridgeman, 1983). A simple way of achieving this is to add the velocity estimates that are derived from afferent and efferent motion signals. The sum of these estimates would result in head-centred motion. For instance, the image on the retina of stationary objects in the world would gain a motion opposite and equal to any eye movement. As suggested above, reafferent retinal motion should provide a velocity estimate of similar magnitude to the efferent estimates of eye movement. If these two estimates are equal to one another, but have opposite sign, then their sum would correctly suggest null motion.
Peripheral vision is the part of vision detected by the eye that occurs at the edges of the central focal point of a person’s gaze. Generally in humans, peripheral vision is much weaker than in other species, specifically in context of differentiating color or shape. Receptor cells on the retina are much more sparse at edges of the eye as opposed to the center which therefore limits the ability to distinguish certain features. (http://www.sciencedaily.com/articles/p/peripheral_vision.htm ) Normal peripheral vision extends 150 degrees laterally in one eye, or 180 with both. This occurs in a participant with ideal vision of 20/20. (http://www.visionrx.com/library/enc/enc_peripheralvision.asp )
The effects of perceptual load on the occurrence of inattentional blindness were demonstrated clearly by experiment. In an experiment conducted by Finch and Lavie in 2007, participants were given identical series of central cross-targets with two arms of clearly different color (blue and green) and slightly different length. Participants were split in two groups, one performing an easy task (low load condition) and the other a harder task (high load condition). The group performing the easiest task only had to make color discrimination between the tw...
The Subordination of the Camera Eye to the Human Subject 2 Film, as a medium of sight, exists primarily as a mode of representation. By the recording of images, a perspective of reality is created and maintained during viewing. The relation between what the camera records and what the viewer perceives is a direct one, which is sustained through the material assumption of the filmic reality as an actual one (The suspension of belief). Citing examples from Psycho (Alfred Hitchcock, 1960), 2001: A Space Odyssey (Stanley Kubrick, 1968), Man With a Movie Camera (Dziga Vertov, 1929), and Blow Up (Michelangelo Antonioni, 1966) this paper will contend that these films assert the prevailing domination of the human viewpoint over that of the “cineeye.”

Binocular vision is vision using both eyes that have overlapping fields of view, therefore there would be differences in what the left and right eye. Binocular vision provides important information for depth perception and binocular cues are an essential aspect of certain visual tasks.

Communication is influenced and perceived by so many different factors, and each individual who participates in communication has their own values and beliefs that will influence how they perceive certain aspects of communication. Perception is such an important aspect in regards to communication and understanding how other people communicate and the reasons why the react to communication the way they do.
... Furthermore there is also a process known as shape constancy that help individuals analyze the stance of objects as constant even though its images may change or alter. This can easily be compared to size constancy. Size constancy is when an individual analyze objects as having a particular size even though the distance may change. An example of this is when we know that a car can fit people inside even though it looks extremely small from far away. In addition there is also lightness constancy which may be thought as similar to shape and size constancy. Lightness constancy depends greatly on relative luminance which is the quantity of light that reflect upon an object that may alter a motion.
There are many different Visual Perception principles in perception. The main principles are Gestalt. Gestalt is a German word meaning 'form' or 'shape'. Gestalt psychologists formulated a series of principles that describe how t...
Any one given experience an organism perceives must incorporate several sensory systems, that involves numerous number of organs , that further more are comprised of millions upon millions of firing cells. Perception is not a direct mirroring of stimulus, but a complex chaotic patterns dependent on the simultaneously activity of neurons. This essay deals primarily with neurons from the optical sensory system. The outer ridge of the brain, known as the cerebral cortex begins the analysis of sensory messages. (1) Nevertheless, visual perception is possibly more widespread than one area of the cerebral cortex and like ly over various subcortical structures and number of different systems as well. (2) One of the many ways for the "perception process" to begin, is vision. Vision is dependent on the interaction between light input and the eye. The visual input is seen through lens that takes different light outside, refract and bend into points of light that focus on specific places on the retina. This light-sensitive tissue that lines the back of the eye consists of interconnected neurons. The three diff erent types are receptor cells, bipolar cells and ganglian cells. When photoreceptors are stimulated, they change in structure of photopigments in the receptors and transduce light input into neural activity. (2) Electrical stimulus trave ls down the axon of bipolar cells to the ganglian cells. The ganglian cells are activated through nerve impulses or action potentials and travel down the optic nerve. This activity conducts along the optic nerve to the geniculate nucleus that then travels to the mid- brain. (2) Finally the firing neurons activity travels to the cortex at the back of the brain, known as the stria...
...occurring in foveal vision away from the midline however this is not visible or obvious when recognition of visual information occurs. There is an overlap at the centre of the fovea where information projects simultaneously to both hemispheres, this being consistent with the bilateral theory. On the other hand, split fovea theory is an interesting theory of fixation effects that has been inspired by previous research unconnected with split fovea theory and thus incapable of providing appropriate evidence. More recently, split fovea theory has been based on experiments conducted specifically in its support but in which fixation locations were not monitored and stimuli exceeded foveal vision. It is good to see that research in the area is beginning to improve but it is difficult to be enthusiastic about any theory when there is no compelling evidence to support it.
If it is done correctly your eyes and brain perceives the object as being in front of you. Basically it is a mind trick.
In 1838, Charles Wheatstone developed that the brain can process distinct two-dimensional images from each eye into a single three-dimensional object. Through a stereoscope, the individual is given a sense of and immersion by looking at both side by side stereoscopic pictures (“History Of Virtual Reality”, n.d.). (This has eventually advanced into the View-Master (F). In the 1930s, the first sources to a more modern idea of virtual reality came from a science fiction writer, Stanley G. Weinbaum which is the short story “Pygmalion’s Spectacles”. It explains the concept of a pair of goggle-based virtual reality system with a holographic recording of the fictional world such as smell, taste and touch.
