The RollerMouse Free by Contour Design is an advanced mousing device that uses a rollerbar to control the cursor movement. The central pointing device eliminates the need for a traditional mouse, although you can also use it as a complement of the latter. The rollerbar slides horizontally and rolls vertically with your fingertips or your palms with very little effort. It provides full control of your cursor with an outstanding accuracy. The RollerMouse fits below your keyboard or laptop. It places the mousing controls right below the keyboard, in a central position, keeping your hands within a small work area to eliminate reaching motions. It also allows your hands to stay in a neutral and symmetrical position and features many innovations which will improve your computing and ergonomics experience. The RollerMouse is a high-end pointing device that uncovers a new and improved way of using your cursor.

Advantages
· Eliminates reaching for a traditional mouse. Asymmetrical reaching with one side of your body and not the other causes your muscle groups to compensate for the weight of your extended arm while reaching for a traditional mouse. Repetitive reaching oftentimes leads to tightness and pain in the neck, shoulder and elbow areas. The RollerMouse Free allows you to keep your elbows comfortably by your side.
· No gripping necessary. The RollerMouse Free is controlled with the use of an unflexed hand, so there is no need to clutch or hold the device in order to navigate the cursor. This eliminates the flexing of your fingers and avoids muscles activity that can lead to numbness, tingling or pain. Your fingertips roll a narrow bar both up and down and from side to side simultaneously to navigate the cursor over the entire screen, with very little friction or resistance.
· Single finger point and click functionality. The control bar rolls and slides easily with one finger, and is also clickable. Clicking on the bar is equivalent to a left mouse click. When the bar reaches the left or right border of the device, the cursor position is automatically readjusted on your screen.
· Outstanding accuracy. The rollerbar works together with an optical sensor which detects your rolling and sliding movements accurately.
· Versatile. The RollerMouse is well suited for both left and right-handers.
· Equal use of both hands. With the mouse buttons centered beneath the keyboard home keys, mouse control is equidistant from either hand. The command buttons are at the fingertips of both hands, which reduces the risk of injuring your dominant mousing hand.
· Tailored to laptop and desktop. The RollerMouse Free has been designed to fit immediately adjacent to your keyboard or laptop. This places the mousing controls just a few inches below the home keys, keeping your hands within a small work area, eliminating large reaching motions.
· Adjusted to your keyboard. The RollerMouse Free comes with keyboard risers to elevate slim keyboards to a height which prevents accidental movement of the rollerbar.
· Included wrist rests. Made of soft and comfortable material, the wrist rests promote neutral wrist posture. They are also removable to reduce the footprint and fit into smaller workspaces.
· Seven button functions. There are two easy options to perform a left click. Either push down on the navigation bar itself, or click on the large left button in the button control area. Other button functions include a traditional right click button, a single touch double click button, a scroll wheel, a scroll lock , one touch copy and one touch paste.
