This mouse has a couple of features
- you only need to be able to hiss to turn it on operate it. No need for spoken words, or vocal cords, or anything but the ability to start making a hissing noise and stop making a hissing noise.
(it does require being able to make the popping noise to make the crosshairs disappear)
This mouse works the same way a fed-ex delivery truck works: It moves every time you start hissing, then makes a 90 degree clockwise turn every time you stop. It follows a pattern: north, east, south, west. So you can aim the mouse in a direction, and if you overshoot, you can go 'around the block' to get to where you are going.
This mouse will allow you to get anywhere on the screen with a series of hisses.
