1.   A small processor built into the mouse translates the movement over that digitized terrain into cursor movements on the screen.

2.   Developed by Dr. Aaron Sones, a retired Los Angeles emergency room physician, the mouse shifts the focus of cursor movement from the hands to the feet.

3.   Like a mouse, it can also control cursor movements.

4.   One pedal controls the cursor movement and speed, while the other handles the point-and-click function.

5.   The result is more accurate cursor movements on the computer screen.

6.   This means, of course, you get fast and accurate cursor movement with very little throw of the actual device.

7.   Cursor movement leaves no trails or shadows behind.

8.   You can adjust the FreeSketch options to control how closely the function interprets the mouse cursor movements.
