There are several types of adaptive technologies. I know screen readers can help those with visual impairments. A braille printer can also help these students keep up with the rest of the class by printing handouts that students are going to be using immediately so that they have all the same materials as their classmates. Certain types of keyboards can help those who have difficulty typing with their special design. There's a type of keyboard that's two orbs which, when working together, type letters. This keyboard can help students who have difficulty typing as a result of impaired fine motor movement and can also assist autistic students as the order of the letters is both alphabetic and color coded as opposed to the seemingly random order of the normal QWERTY keyboard. I've never used any of these myself, nor do I know anyone who has used them. I see that it's possible that other students may want to use them because they're "interesting" in the beginning, and cost may be a negative in getting such tools.

You can use facebook to keep up with technology trends. As a social networking site facebook often has interesting videos on new technology, it's where I learned of several types of adaptive keyboards that can help students with disabilities. Also, you can network with other educators to keep up with specifically educational technology or how to use "regular" technology educationally.
