The Contour Design RollerMouse Red Plus is the latest generation of the proven Rollermouse family, which all use a rollerbar instead of a traditional mouse, positioned between the user and their keyboard or laptop. This allows the user to avoid the 'reach' for the mouse, and move their cursor and click in the space between themselves and their keyboard. This model differs from the RollerMouse Red in that it has an extra deep palm support (5.12" vs 2.87" on the Red) which affords individuals with very large hands more appropriate support.
The cursor is moved by rolling a '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. Eight buttons and a scroll wheel are located below the bar to generate left/middle/right/double clicks, copy, paste and vertical scrolling.
