More computer access for all!

Being so intrigued by the new features I learned about while typing my last post, I felt compelled to research some more!
I can help some of my students in very easy ways just by knowing more about the computer in front of me..so I hope this helps you too!

I'm going to start off by saying assistive technology that allows computer access for students with disabilities exists on a continuum from low tech to high tech. It's called the assistive technology continuum.This allows us to distinguish between devices.

I didn't know about all of the different types of alternative keyboards out there! below I list a few and who they would be good for to give you an overview and an idea about these!

• expandable keyboards: poor motor skills, in need of large target area, cognitive deficits.
• mini keyboards: restricted motion range, use of only one hand.
• On screen keyboards- visual perceptions, easier to locate on screen, can't use a keyboard

Not only are they alternatives for keyboards, but also for mouse devices as well! Here are a few!

• trackballs- mini to large: good and poor motor skills, but limited range in motion, able to use feet, younger students.
• joysticks: poor gross and motor skills, need to operate with other body parts other than hands
• eye gazing system- cannot use hand or head, can control eye movements, can keep head up and still

Now what about students with vision impairments or blindness? Well there are input and output devices that can make a computer accessible for them by magnifying the screen, or providing them with screen reading applications, and Braille displays!

The possibilities seem endless and it is so reassuring to know we can help everyone! : )

Below I was interested in how visually impaired or blind people would use new technology and below!

Also, in my research I found the Iphone and Ipad both have an accessibility option for blind users!
