Here is a video I have found that further describes assistive technologies that exist and how they can benefit people with disabilities.
This video gives a definition of Assistive Technology then goes on to describe different types such as, those for the visually impaired (screen reader, closed circuit magnification, Braille translation devices etc.), those for the developmentally and physically challenged (adaptive keyboard, alternate communication devices, adaptive student desks etc.) and those for the deaf and hard of hearing (personal amplification device, audio/visual communication devices, voice to text translation etc.) It shows pictures of each technology or device and describes (most of the time) how it is used.
This video was made by students in an Introduction to Special Education class at Townson University .

ENJOY!
