OrthoMouse

The OrthoMouse from Orthovia is designed to put your hand in the 'position of function'. When you flex your fingers (i.e. curling your fingers into a ball) you are using the flexor muscles in your hand. When you open your hand (extending your fingers to a straight position) you are using your extensor muscles. The position of function is the point of balance between these two sets of muscles. This design also enhances the tactility of the mouse by using the extra sensitivity in your fingertips to provide maximum precision and accuracy.

The sensor is near the 'top' or tip of the mouse, directly below your fingertips, making the act of targeting and positioning the cursor a direct extension of your fingers (much like writing).

In order to accommodate the various hand sizes, the OrthoMouse comes with several slide-on attachments at the base and top of the mouse to accommodate different hand sizes and methods of use. This ensures an increased sense of tactility and confidence in cursor positioning, resulting in a very small learning curve. This mouse is ideally suited for anyone who is seeking a sense of precision and high tactile feedback including graphics designers and gamers.

• Six possible configurations of mouse shape: Not all hands are alike. The OrthoMouse is adaptable to the size, shape and function of your hand and fingers by means of special adapters that are easy to exchange and are all included in the package. You choose and insert the adapter that fits your hand best and feels most comfortable among six possible shape configurations.
• Unique design for fingers and thumb: The OrthoMouse is designed so that it supports the hand and fingers evenly while they adopt the correct and innocuous position - the 'Position of Function' during the use of the OrthoMouse. Your hand works and rests (between periods of activity) in the 'Position of Function'. The thumb remains in opposition to the other fingers at all times, which is the main distinguishing characteristic of the human hand. John Napier, states: "Perhaps the most important movement of the human hand is opposition". It allows control, tactility and precision, since the fingers assume a position very similar to the one used during writing.
• Scroll buttons replace awkward scroll wheel: The thumb on the OrthoMouse is responsible for the scroll features - you move it up for scrolling upwards, down for scrolling downwards, and press the thumb mid button for the 'scrolling click'.
