This collection of websites is intended to answer the delicate question of "how do they do that" in regard to assistive technology.  How does your sight impaired or blind client or student "read" the computer screen?  How does someone with only above the neck mobility activate a computer?  And don't forget, limitations may include cognitive and neural issues which have devices and software to addess those issues.

Sophisticated hardware devices are run through a serial port, and these devices run on software that are designed to be compatible with the Windows operating system.

Oh, by the way, what is and where is a serial port?  Click on the view in frames button below to see the related websites.
