Assistive Technology for the Differently Abled for Computer Accessibility Mrunalini Assistive technology umbrella term includes assistive, adaptive, and rehabilitative devices PWD includes the process used in selecting, locating, and using them. Assistive technology can ameliorate the effects of disabilities that limit the ability to perform ADLs. Uses of Assistive Tech promotes greater independence Enable PWD with the technology needed to accomplish tasks limited due to disability. For example wheelchairs provide independent mobility assistive eating devices can enable people who cannot feed themselves, to do so. PWD - more positive and easygoing lifestyle increase in "social participation,“ "security and control," "reduce institutional costs without significantly increasing household expenses. Billion PWD - WHO their poverty rate is about twice as high. So technologies that could help disabled people contribute more in the workplace improve their quality of life If a million more disabled people could work, the economy would grow (1.7%). Computer accessibility accessibility of a computer system to all people, regardless of disability type or severity of impairment. specialized hardware or software, or a combination of both, designed to enable use of a computer by a PWD. Specific technologies may be referred to as assistive technology. Special-needs Assessment by an assistive technology consultant (such as an occupational therapist, a rehabilitation engineering technologist, or an educational technologist) to help them identify and configure appropriate assistive technologies to meet individual needs. remote desktop software and a web cam from home too the assessor logs on to the client's computer via a broadband internet connection, observes the users computer skills, and then remotely makes accessibility adjustments to the client's computer where necessary. Technology for Multiple Sclerosis: Eyegaze Edge - fits in a suitcase. The technology behind Eyegaze is called Pupil Centre/Corneal Reflection, or PCCR. A tablet is set up in front of the user, with a small video camera underneath. A near-infrared LED (light-emitting diode) light illuminates the user's eye. The camera then measures the distance between the centre of your pupil and the reflection of LED light on your cornea - the transparent bit of your eye at the front. This tiny distance shifts as your gaze changes, and this enables a computer to work out exactly where you're looking. Technology for Head control HeadMouse Nano - A camera tracks the movements of a reflective dot stuck to the user's forehead, and these motions control a computer cursor. Selections are made using a
