Assistive Technology

[Agnes]

Assistive technology refers to hardware and software designed to help people with disabilities. Some types of assistive technology provide physical assistance, while others provide helpful aids for individuals with learning disabilities.
Examples of common assistive devices include hearing aids, wheelchairs, and prosthetics. Hearing aids amplify sound, helping individuals who have difficulty hearing. Modern hearing aids even filter out background noise and clarify speech, making conversation easier. Wheelchairs provide mobility for individuals who are unable to walk. Motorized wheelchairs provide a means of transportation for people with limited upper body function. Prosthetics can replace missing body limbs, such as arms or legs. Some modern prosthetics even allow people to control appendages, such as the fingers on a prosthetic hand.
Software designed to help individuals with physical limitations is often called Accessibility software. Popular operating systems, such as Windows, OS X, and iOS include several accessibility features. Some examples include:
Assistive software may also be designed for educational purposes. For example, a specialized reading program may help students with dyslexia. Math tutor programs can provide a way for students to learn mathematical concepts at a comfortable pace. Memory applications can help individuals with brain injuries restore their memorization capabilities.
NOTE: While not designed as assistive technology, touchscreen devices such as tablets are commonly used as assistive devices since they provide a natural user interface.
