The term disability is used to define those individuals in society whose physical or psychological abilities are not sufficiently developed to carry out, satisfactorily, daily activities. These deficiencies can not only affect the behavior of those who suffer from it, but also how society sees it and the interaction it has with it. The use of this word is considered controversial, because, in scientific fields, the use of the word does not determine a derogatory sense, however, its current use tends to label the person who designates the term in an offensive way.
The concept emerged at the end of the First World War, when the human and material damages left by the battles were analyzed, focusing on the physically affected soldiers (mutilations, reduced mobility). They needed special treatment from the government, since they did not have the ability to fend for themselves that they previously did. From their birth, the definition of disability has been developed, adding or simplifying the physical characteristics that someone would have to be within this group; for example, during the decade of the 60s, it was thought that lefties were disabled and were forced to write by hand right, thinking this because right-handed people were more common and products such as scissors were always designed for them.
Currently, it seeks to adapt public spaces for people with disabilities, in this way it is easier for them to carry out activities and social exclusion is avoided. However, it is very generalized in the needs of each of these subjects. Disability can be classified into mental (different psychological condition), physical (lack of limbs, inability to move limbs), auditory (loss of hearing or inability to hear with any of the devices) and visual (loss of sight or difficulty in the processOf vision). According to various studies, there are three reasons that can trigger the appearance of a disability: social or contextual causes (armed conflicts), health causes (diseases, infections or bacteria) and environmental causes (pollution).
Studies are often carried out to help discover technology that can help improve the quality of life of people with disabilities. It also analyzes what aspects of life can affect having a condition that places you at a disadvantage, in this way solutions were devised to develop these activities correctly.
