Cykey Microwriting Keyboard-PDA or PC
There are so many adaptive keyboards on the market but this one is very interesting, flexible and, may I say, charming. This little wireless, one-handed keyboard for either hand uses infrared to an IR receiver on a laptop or desktop computer, but it can also use the IR receiver on a Palm unit directly. It costs between $100-$150. The batteries last for six to nine months of use.
There is a video online that shows the usage of the keyboard.Cykey Keyboard
