The Contour Deisgn RollerMouse Pro2 is a central pointing device which uses a rollerbar instead of a traditional mouse and is designed to sit immediately in front of your keyboard below the space bar. This allows the user to avoid the 'reach for the mouse, and move their cursor with the rollerbar.
The cursor is moved by rolling a 6.125" 'dowel' or cylinder-shaped bar with the fingertips to achieve 'up' and 'down' movement, and sliding this bar from side to side for horizontal movement. Pressing down on the bar will create a left click action. Five buttons and a scroll wheel are located below the bar to generate left/middle/right/double clicks, copy, paste and vertical scrolling.
