ERGONOMIC BENEFITS

Reduces Pronation – There is a notch on one side in which to place your thumb, and the mouse slopes downward on the opposite side. This puts your hand at a 17 (degree) angle, which is a more natural position for your hand.
No Need to Grip – This design means that the force of gravity on the hand alone provides all the control required to move the mouse; there is no need to grip the mouse.
Reduces Pain and Force of Clicking – The tips of the fingers should hang over the end of the mouse slightly, which allows the user to click with the base of the first segment of the finger; meaning the user is not bending, hovering or lifting up the finger, resulting in 1/10th of the muscles required to perform the clicking action. Because the fingers are not poised in preparation to click, the “clicking fingers” remain relaxed, outstretched and supported at all times.

FEATURES

      • Multiple Sizes for both Left and Right Hands: The CMO is available in small, medium and large for the right hand, and medium and large for the left hand. 
      • Sculpted, Elevated Buttons: This enables the hand to remain open with the fingers extended in a ready position for quick button activation. Buttons are elevated and shaped to reduce excess load on the fingertips.
      • Thumb Support with Integrated Scroll Wheel & Two Position Rocker Switch: The two position side rocker switch uses very light touch internal switches and is designed not to require pinch force to activate. The switches “click” with a very slight forward or backward motion of the thumb. The rocker switch is rubber coated and textured to provide maximum grip, with little effort.
      • Elevated Wrist Support: Reduces pressure on the wrist by keeping it off the desk top. Maintains a straighter wrist alignment and minimizes Lateral Deviation. Balances the hand in a neutral, tilted posture. Presents static grip by allowing the hand to rock freely.
      • Programmable Software: Programming software (this is a link) for PC and MAC is available for download and allow customization of the CMO to accomplish tasks faster and easier.Ergonomic Research on the CMO (we do not have this, can we use what we have for PerFit?)

1997Contour Success Story in Silicon Valley Chevron, Silicon Graphics & EORM get Pro-Active with the Contour Perfit Mouse in their ergonomics programs 
1996ISO 9241-9 Ergonomic Testing The following is an exerpt from the Study done by Global Ergonomic Testing, comparing the Contour Mouse with the popular Microsoft Ergonomic Mouse. “…significantly less muscle effort and postural deviation from neutral occurred with the Contour mouse. In addition, the Contour mouse was significantly more positively rated for ease of use, comfort, and design.”
