Overview of Assistive Technology

Assistive technology is any tool that helps a person with a disability accomplish everyday tasks more easily. A specially designed “rocker” knife that makes it easier to cut food with the use of one hand is considered assistive technology . In computer terms, assistive technology helps people accomplish two fundamental tasks: input and output. These tools are not web specific; web usage is just one component of their overall utility.

Tip

Don’t overlook your own computer’s capabilities. Windows XP and Mac OS X both include a lot of support for accessibility by default, and Sun Microsystems’ Solaris 10 includes full accessibility support with voice capabilities, screen magnification, and onscreen keyboard functions.
