Adapted Keyboards

Adapted keyboards are one the most versatile types of Assistive Technology. This type of AT helps students with limited fine motor skills, cognitive disabilities, and vision impairments, to name a few.
My first introduction to the adapted keyboard was in an office setting. You may have seen them as well. The keyboard was angled from preventing, and helping users that had already developed, carpel tunnel syndrome.

Of course the adaptability of these keyboards differs significantly in the special education realm. These types of keyboards look much different depending on how they are modified. 

Here's a video of one of the biggest Assistive Technology companies in adapted keyboards, Chester Creek Technology.
