What is visual?

Visual is a term that comes from the Latin word visuālis. The concept refers to what is linked to vision (act and result of seeing: that is, perceiving objects through the eyes thanks to light).

From these definitions, we can analyze multiple expressions that are composed with the notion of visual. The visual field, for example, is formed by the space that a person can see with his eyes. This space varies in each individual according to factors such as possible diseases, eye disorders, etc. Perimetry is the technique for measuring the visual field of an individual. The larger the field of view, the subject can cover a larger area with their vision.

Visual perception, in turn, is linked to how the individual interprets stimuli according to the effects of light, emotions and knowledge. This concept, therefore, is also associated with the idea of ​​vision. The structure that allows the capture of light is known as the visual system. Visual cortex, Visual receptor, and Visual stimulus are other expressions related to different aspects of vision. Visual memory, on the other hand, can refer to the physical means that record images of important events (such as a mural or documentary) or a person’s ability to remember what they see. Each individual tends to cling to different issues to store their memories, and visual memory is especially appreciated by those people who know how to quickly locate themselves on the street when they see a store, a building, or even a mark on the wall that caught their attention on the street. first time. and then they associated it with the geographic area. On the other hand, visual memory also includes the retention of faces with a great level of detail, so that a person can easily remember and recognize another, even if they have not seen them more than once and for a short period of time. It is important to highlight that this form of memory begins to act from the first days of life, since it does not necessarily require an interpretation for objects, although it becomes more complex and effective when reaching adulthood. Both visual memory and a person’s visual ability and visual perception can be assessed using the Benton test , which is usually applied to individuals with Alzheimer’s, attention deficit disorder, learning or reading problems, among others.

During the Benton test, the patient must observe ten cards, each with a different design, and once the exposure time is over, they must be removed from memory. Once this is done, the second phase arrives, in which you are asked to copy the drawings again, but this time looking at the cards directly. The resulting drawings are evaluated to issue a rating for each of the following categories: distortions, omissions, rotations, dimensional errors, loss and conservation. In the field of computing , Visual Basic is the name of a programming language that Alan Cooper introduced in 1991 . The main objective of creating Visual Basic was to simplify the programming process, and this was possible thanks to its integration with a specific development environment, which offered the user a large number of tools to help him in his work, such as the search by function and property names, plus autocompletion and error handling. Visual C++ is also a computing concept: in this case it refers to an integrated development environment for various programming languages.
