In human–computer interaction, computer accessibility (also known as accessible computing) refers to the accessibility of a computer system to all people, regardless of disability or severity of impairment. The term "accessibility" is most often used in reference to software; when specialized hardware, or a combination of specialized hardware and software, is used to enable use of a computer by a person with a disability or impairment, it is often referred to as assistive technology. There are numerous types of impairment that affect computer use. These include: *Cognitive impairments and learning disabilities, such as dyslexia, ADHD or autism. *Visual impairment such as low-vision, complete or partial blindness, and color blindness. *Hearing-related disabilities including deafness, being hard of hearing, or hyperacusis. *Motor or dexterity impairment such as paralysis, cerebral palsy, or carpal tunnel syndrome and repetitive strain injury. These impairments can present themselves with variable severity; they may be acquired from disease, trauma or may be congenital or degenerative in nature. Accessibility is often abbreviated as the numeronym a11y, where the number 11 refers to the number of letters omitted. This parallels the abbreviations of internationalization and localization as i18n and l10n respectively. == Special-needs assessment== People wishing to overcome an impairment in order to use a computer comfortably and productively may require a "special needs assessment" by an assistive technology consultant (such as an occupational therapist or clinical scientist) to help them identify and configure appropriate assisstive hardware and software. When a disabled person is unable to leave their own home, it may be possible to assess them remotely using remote desktop software and a web cam. The assessor logs on to the client's computer via a broadband Internet connection and then remotely makes accessibility adjustments to the client's computer where necessary. Additionally, the assessor is able to observe their computer usage. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Computer accessibility」の詳細全文を読む スポンサード リンク
