Courtesy : Audio/Visual Study See also: Two-streams hypothesis The major problem in visual perception is that what people see is not simply a translation of retinal stimuli (i.e., the image on the retina). Thus people interested in perception have long struggled to explain what visual processing does to create what is actually seen.…

Courtesy : Audio/Visual Visual perception is the ability to interpret the surrounding environment through photopic vision (daytime vision), color vision, scotopic vision (night vision), and mesopic vision (twilight vision), using light in the visible spectrum reflected by objects in the environment. This is different from visual acuity, which refers to how clearly a person sees (for example “20/20 vision”). A person can have…

Courtesy: Audio/Visual Other functions Balance Along with proprioception and vestibular function, the visual system plays an important role in the ability of an individual to control balance and maintain an upright posture. When these three conditions are isolated and balance is tested, it has been found that vision is the most significant contributor…

Whereas a V1 neuron may respond selectively to a line segment of a particular orientation in a particular retinotopic location, neurons in the lateral occipital complex respond…

At this point, the information coming from both eyes is combined and then splits according to the visual field. The corresponding halves of…

Courtesy : Audio/Visual The visual system comprises the sensory organ (the eye) and parts of the central nervous system (the retina containing photoreceptor cells, the optic nerve, the optic tract and the visual cortex) which gives organisms the sense of sight (the ability to detect and process visible light) as well as enabling the formation of several non-image photo response functions. It detects and interprets information from the optical spectrum perceptible to that species…

Courtesy : Audio/Visual Commercial The professional audiovisual industry is a multibillion-dollar industry, comprising manufacturers, dealers, systems integrators, consultants, programmers, presentations professionals, and technology managers of audiovisual products and services. Commercial audiovisual can be a lengthy process to install and configure correctly. Boardroom audiovisuals can be installed for a number of reasons and…
