In my last bit of blogging, I mentioned computer devices that are useful for kids with special needs. Here’s the world’s largest trackball — the Greystone Peripheral BigTrack.

This monster mouse has a three-inch yellow ball in the center, useful for people who lack fine motor skills. Two huge blue buttons for the left and right mouse clicks are located behind the trackball so they won’t get clicked accidentally. It’ll work with Windows and Mac computers that have a USB or PS/2 port.

If you’re using this in a learning situation, you can hook up a regular mouse for “driver training” or simply for simultaneous participation.

Another version of the same product also works with switches, but not the kind sold by Cisco. These are devices that allow kids with physical disabilities to access computer programs without the use of a mouse. If you happen to have a preference, let us know!
