The Evoluent™ VerticalMouse™ 3 is the advanced third generation of the revolutionary mouse from the original inventor of the handshake grip. The vertical shape of the Evoluent Mouse provides the most neutral posture of the wrist and forearm for any mouse we've tried. That's why the Evoluent is without a doubt the most popular input device in our range.

The Evoluent VerticalMouse was evaluated in 2007 by a team at the health services clinic in UC Berkeley, including medical doctors, physical therapists, ergonomists, and administrators. It was found to be comfortable, easily adapted to, and promoted a neutral wrist and forearm posture. It is the only vertical type mouse approved for staff use within UC Berkeley and for sale in the campus store.

The Evoluent has a patented shape which supports your hand in a fully upright handshake position - eliminating forearm twisting.

To see what we mean, place your hand palm down with your fingers flat on the desk. Notice that your comfort level increases as you rotate your forearm outward. That is, your hand is now side-on with your little finger resting on the desk and your thumb in a relaxed position resting on or near your index finger.

The VerticalMouse does not move sideways when clicking with normal force because the thumb naturally opposes the fingers. Pointer control is as accurate as any other mouse when the pointer speed settings are properly adjusted. All 5 buttons are easily operable without contorting your fingers. The button force is light for easy clicking, but still firm enough to avoid accidental actuation.
