Today’s invention is a computer mouse which rides on a pair of wheels, which is free to rotate about a vertical axis. The wheels are powered in such a way that when the cursor is placed on certain graphical elements on the screen, the mouse can be physically driven (across the desktop) as the cursor moves towards the next item that needs attention on the screen.
This system can be used as a training device to help someone learn a specified sequence of repeated screen interactions, for example.
