Assistive technology (AT) is a term for assistive, adaptive, and rehabilitative devices for people with disabilities and the elderly. Disabled people often have difficulty performing activities of daily living (ADLs) independently, or even with assistance. ADLs are self-care activities that include toileting, mobility (ambulation), eating, bathing, dressing, grooming, and personal device care. Assistive technology can ameliorate the effects of disabilities that limit the ability to perform ADLs. Assistive technology promotes greater independence by enabling people to perform tasks they were formerly unable to accomplish, or had great difficulty accomplishing, by providing enhancements to, or changing methods of interacting with, the technology needed to accomplish such tasks. For example, wheelchairs provide independent mobility for those who cannot walk, while assistive eating devices can enable people who cannot feed themselves to do so. Due to assistive technology, disabled people have an opportunity of a more positive and easygoing lifestyle, with an increase in "social participation", "security and control", and a greater chance to "reduce institutional costs without significantly increasing household expenses." In schools, assistive technology can be critical in allowing students with disabilities to access the general education curriculum. Students who experience challenges writing or keyboarding, for example, can use voice recognition software instead. Assistive technologies assist people who are recovering from strokes and people who have sustained injuries that affect their daily tasks.
In 1998, the U.S. Congress amended the Rehabilitation Act to require federal agencies to make their electronic and information technology accessible to people with disabilities. Section 508 was enacted to eliminate barriers in information technology, to make available new opportunities for people with disabilities and to encourage the development of technologies that will help achieve these goals. The law applies to all federal agencies when they develop, procure, maintain, or use electronic and information technology. Under Section 508, agencies must give employees with disabilities and members of the public access to information that is comparable to the access available to others.
The World Wide Web Consortium (W3C)'s Web Accessibility Initiative (WAI) is an effort to improve the accessibility of the World Wide Web for people with disabilities. People with disabilities encounter difficulties when using computers generally, but also on the Web. Since they often require non-standard devices and browsers, making websites more accessible also benefits a wide range of user agents and devices, including mobile devices, which have limited resources. According to a US government study, 71% of website visitors with disabilities will leave a website that is not accessible.
Perkins School for the Blind, in Watertown, Massachusetts, was founded in 1829 and is the oldest school for the blind in the United States. It has also been known as the Perkins Institution for the Blind.
Adobe Authorware was an elearning authoring tool with its own interpreted, flowchart-based, graphical programming language. Authorware was used for creating interactive elearning programs that could integrate a range of multimedia content, particularly electronic educational technology applications. The flowchart model differentiated Authorware from other authoring tools, such as Adobe Flash and Adobe Director, which rely on a visual stage, time-line and script structure.
Accessibility is the design of products, devices, services, vehicles, or environments so as to be usable by people with disabilities. The concept of accessible design and practice of accessible development ensures both "direct access" and "indirect access" meaning compatibility with a person's assistive technology.
Computer accessibility refers to the accessibility of a computer system to all people, regardless of disability type or severity of impairment. The term accessibility is most often used in reference to specialized hardware or software, or a combination of both, designed to enable the use of a computer by a person with a disability or impairment. Computer accessibility often has direct positive effects on people with disabilities.
A screen reader is a form of assistive technology (AT) that renders text and image content as speech or braille output. Screen readers are essential to people who are blind, and are useful to people who are visually impaired, illiterate, or have a learning disability. Screen readers are software applications that attempt to convey what people with normal eyesight see on a display to their users via non-visual means, like text-to-speech, sound icons, or a braille device. They do this by applying a wide variety of techniques that include, for example, interacting with dedicated accessibility APIs, using various operating system features, and employing hooking techniques.
Web accessibility, or eAccessibility, is the inclusive practice of ensuring there are no barriers that prevent interaction with, or access to, websites on the World Wide Web by people with physical disabilities, situational disabilities, and socio-economic restrictions on bandwidth and speed. When sites are correctly designed, developed and edited, more users have equal access to information and functionality.
Service and supports for people with disabilities are those government or other institutional services and supports specifically provided to enable people who have disabilities to participate in society and community life. Some such services and supports are mandated or required by law, some are assisted by technologies that have made it easier to provide the service or support while others are commercially available not only to persons with disabilities, but to everyone who might make use of them.
Inclusive design is a design process in which a product, service, or environment is designed to be usable for as many people as possible, particularly groups who are traditionally excluded from being able to use an interface or navigate an environment. Its focus is on fulfilling as many user needs as possible, not just as many users as possible. Historically, inclusive design has been linked to designing for people with physical disabilities, and accessibility is one of the key outcomes of inclusive design. However, rather than focusing on designing for disabilities, inclusive design is a methodology that considers many aspects of human diversity that could affect a person's ability to use a product, service, or environment, such as ability, language, culture, gender, and age. The Inclusive Design Research Center reframes disability as a mismatch between the needs of a user and the design of a product or system, emphasizing that disability can be experienced by any user. With this framing, it becomes clear that inclusive design is not limited to interfaces or technologies, but may also be applied to the design of policies and infrastructure.
Visual or vision impairment is the partial or total inability of visual perception. For the former and latter case, the terms low vision and blindness respectively are often used. In the absence of treatment such as corrective eyewear, assistive devices, and medical treatment – visual impairment may cause the individual difficulties with normal daily tasks including reading and walking. In addition to the various permanent conditions, fleeting temporary vision impairment, amaurosis fugax, may occur, and may indicate serious medical problems.
Digital accessible information system (DAISY) is a technical standard for digital audiobooks, periodicals, and computerized text. DAISY is designed to be a complete audio substitute for print material and is specifically designed for use by people with "print disabilities", including blindness, impaired vision, and dyslexia. Based on the MP3 and XML formats, the DAISY format has advanced features in addition to those of a traditional audio book. Users can search, place bookmarks, precisely navigate line by line, and regulate the speaking speed without distortion. DAISY also provides aurally accessible tables, references, and additional information. As a result, DAISY allows visually impaired listeners to navigate something as complex as an encyclopedia or textbook, otherwise impossible using conventional audio recordings.
Within the field of human–computer interaction, accessibility of video games is considered a sub-field of computer accessibility, which studies how software and computers can be made accessible to users with various types of impairments. It can also include tabletop RPGs, board games, and related products.
In 2003 and following years, initiatives were instituted to improve internet access for people with disabilities in the Philippines. These measures were inspired by the UNESCAP "Asia-Pacific Decade for Disabled Persons" (1993–2002). Key organizations included the government body National Council for the Welfare of Disabled Persons (Philippines) and the private sector body Philippine Web Accessibility Group (PWAG). The "Disabled Friendly Website Awards" were launched to encourage web designers to incorporate universal access. Since 2009 unhampered access to Information and Communications Technology (ICT) has been in the second National Human Rights Action Plan of the Philippine government.
NonVisual Desktop Access (NVDA) is a free and open-source, portable screen reader for Microsoft Windows. The project was started by Michael Curran in 2006.
Accessible publishing is an approach to publishing and book design whereby books and other texts are made available in alternative formats designed to aid or replace the reading process. It is particularly relevant for people who are blind, visually impaired or otherwise print disabled.
Design for All in the context of information and communications technology (ICT) is the conscious and systematic effort to proactively apply principles, methods and tools to promote universal design in computer-related technologies, including Internet-based technologies, thus avoiding the need for a posteriori adaptations, or specialised design.
Learning Ally, previously named Recording for the Blind & Dyslexic (RFB&D), is a non-profit volunteer organization operating nationwide in the United States. It produces and maintains a library of educational accessible audiobooks for people who cannot effectively read standard print because of visual impairment, dyslexia, or other disabilities.
Under Italian Law 104/1992, "disability" is defined as a loss of the ability of the person to perform basic daily activities unaided."
