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 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 abstained injuries that effect their daily tasks.
A flush toilet is a toilet that disposes of human waste by using the force of water to flush it through a drainpipe to another location for treatment, either nearby or at a communal facility, thus maintaining a separation between humans and their waste. Flush toilets can be designed for sitting or squatting, in the case of squat toilets. Most modern sewage treatment systems are also designed to process specially designed toilet paper. The opposite of a flush toilet is a dry toilet, which uses no water for flushing.
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.
In human–computer interaction, WIMP stands for "windows, icons, menus, pointer", denoting a style of interaction using these elements of the user interface. Other expansions are sometimes used, such as substituting "mouse" and "mice" for menus, or "pull-down menu" and "pointing" for pointer.
A squat toilet is a toilet used by squatting, rather than sitting. This means that the posture for defecation and for female urination is to place one foot on each side of the toilet drain or hole and to squat over it. There are several types of squat toilets, but they all consist essentially of a toilet pan or bowl at floor level. Such a toilet pan is also called a "squatting pan". A squat toilet may use a water seal and therefore be a flush toilet, or it can be without a water seal and therefore be a dry toilet. The term "squat" refers only to the expected defecation posture and not any other aspects of toilet technology, such as whether it is water flushed or not.
A public toilet, restroom, public bathroom or washroom is a room or small building with toilets and sinks for use by the general public. The facilities are available to customers, travelers, employees of a business, school pupils and prisoners and are commonly separated into male and female toilets, although some are unisex, especially for small or single-occupancy public toilets.
Universal design is the design of buildings, products or environments to make them accessible to people, regardless of age, disability or other factors. It addresses common barriers to participation by creating things that can be used by the maximum number of people possible. Curb cuts or sidewalk ramps, which are essential for people in wheelchairs but also used by all, are a common example of universal design.
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.
Grab bars are safety devices designed to enable a person to maintain balance, lessen fatigue while standing, hold some of their weight while maneuvering, or have something to grab onto in case of a slip or fall. A caregiver may use a grab bar to assist with transferring a patient from one place to another. A worker may use a grab bar to hold on to as he or she climbs, or in case of a fall.
The U.S. Centers for Disease Control and Prevention defines aging in place as "the ability to live in one's own home and community safely, independently, and comfortably, regardless of age, income, or ability level".
Accessible toilets are toilets that have been specially designed to better accommodate people with physical disabilities. Persons with reduced mobility find them useful, as do those with weak legs, as a higher toilet bowl makes it easier for them to stand up. Additional measures that can be taken to add accessibility to a toilet include providing more space, adding grab bars to ease transfer to and from the toilet seat, and providing extra room for a caregiver if necessary. Some countries have requirements concerning the accessibility of public toilets. Toilets in private homes can be modified (retrofitted) to increase accessibility.
A toilet is a piece of sanitary hardware that collects human urine and feces, and sometimes toilet paper, usually for disposal. Flush toilets use water, while dry or non-flush toilets do not. They can be designed for a sitting position popular in Europe and North America with a toilet seat, with additional considerations for those with disabilities, or for a squatting posture more popular in Asia, known as a squat toilet. In urban areas, flush toilets are usually connected to a sewer system; in isolated areas, to a septic tank. The waste is known as blackwater and the combined effluent, including other sources, is sewage. Dry toilets are connected to a pit, removable container, composting chamber, or other storage and treatment device, including urine diversion with a urine-diverting toilet.
A wheelchair is a chair with wheels, used when walking is difficult or impossible due to illness, injury, problems related to old age, or disability.
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.
Transgenerational design is the practice of making products and environments compatible with those physical and sensory impairments associated with human aging and which limit major activities of daily living. The term transgenerational design was coined in 1986, by Syracuse University industrial design professor James J. Pirkl to describe and identify products and environments that accommodate, and appeal to, the widest spectrum of those who would use them—the young, the old, the able, the disabled—without penalty to any group. The transgenerational design concept emerged from his federally funded design-for-aging research project, Industrial design Accommodations: A Transgenerational Perspective. The project's two seminal 1988 publications provided detailed information about the aging process; informed and sensitized industrial design professionals and design students about the realities of human aging; and offered a useful set of guidelines and strategies for designing products that accommodate the changing needs of people of all ages and abilities.
Accessible housing refers to the construction or modification of housing to enable independent living for persons with disabilities. Accessibility is achieved through architectural design, but also by integrating accessibility features such as modified furniture, shelves and cupboards, or even electronic devices in the home.
