Tutorial Seven: Assistive technology

Assistive technology: is a term that includes assistive, adaptive, and rehabilitative devices for individuals with disabilities and includes the process used in selecting, locating, and using them.
The Technology-Related Assistance for Individuals with Disabilities Act of 1988 (US Public Law 100-407) states that it is "technology designed to be utilized in an assistive technology device or assistive technology service."
Assistive technology promotes greater independence by enabling people to perform tasks that they were formerly unable to accomplish, or had great difficulty accomplishing, by providing enhancements to or changed methods of interacting with the technology needed to accomplish such tasks.(Retrieved, June, 7, 2010, http://en.wikipedia.org/wiki/Assistive_technology)


Special keyboards: “For those with limited hand function and mobility, large keyboards and a special mouse may be helpful. Larger keyboards perform the same function as other keyboards and have the typical “QWERTY” layout; however, the keys are four times larger than typical keyboard keys. A modified mouse could be one that uses a trackball to move the screen cursor. This type of mouse is particularly helpful for those with fine motor or mobility limitations. Also, younger students with learning disabilities could use a picture keyboard. Students press on a particular picture, and the word goes onto the screen”.

The large keyboard is also useful for individuals who have sight impairment. The keyboards are a set neon yellow with black writing to allow the individual using the device, maximum potential to see the letters and numbers on the keyboard.

In general, assistive technology is usually quite expensive as there isn’t much competition within that area of merchandise.

The special keyboard allows individuals with different disabilities, such as hand function and mobility impairments, learning difficulties, or eye sight impairment, to use a computer independently.

The larger size keys and mouse permit smaller or not so fine movements to operate the computer as there is more room for mistakes and error.
The contrasting colours (neon yellow and black) allow for the highest potential for sight of the letters on the key.
