Knowing The Facts about the "Handshake Mouse"

The patented shape of Ergonomic Evoluent Mouse 4 supports your hand in a fully upright handshake position that eliminates forearm twisting. Mouse 4 is the newest, improved version. Many users said earlier models relieved their hand, wrist, or arm pain.

An ordinary horizontal mouse requires your forearm to twist away from its natural position.

SIZES and VERSIONS: The newest version (Vertical Mouse 4) is available in Right-handed, Left-Handed and Small-size. Note: The Purple model is the Small Right Handed Mouse (To View the Sizing Chart, Click on picture thumbnails at the top of page).  Choose your version at checkout. Also available wireless for the right hand (See Vertical Mouse 3 Wireless page).

Save your Hands and Work Pain Free! 

The grip is the same as an ordinary mouse, just turned sideways into a handshake position. Many users said they got used to it very quickly.

The Vertical Mouse 4 does not move sideways when clicking with normal force because the thumb naturally opposes the fingers. Pointer control is as accurate as any other good mouse when the pointer speed settings are properly adjusted.

All 6 buttons are easily operable without contorting your fingers. The button force is light for easy clicking, but still firm enough to avoid accidental actuation.

A small lip on the bottom edge prevents the little finger from rubbing the desk.

NEW FEATURES of the newest version - the Evoluent Vertical 4:
- more contoured shape to better fit users' hands
- the option to change cursor speed without changing your grip on the mouse
- a sleep mode to conserve notebook battery power.

The Evoluent Vertical Mouse is the only approved ergonomic mouse of University of California at Berkeley. The Evoluent Vertical Mouse 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 and easily adapted to, and the Evoluent mouse promotes 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 Vertical Mouse 4 is designed to encourage an arm neutral position, much like a handshake. (Click on small photos above.) Many users find this completely eliminates their wrist pain.

By comparison, an ordinary mouse twists your forearm into an unnatural and uncomfortable position- especially if you spend long hours at a computer. A small lip on the VM4 keeps your little finger from dragging on the mousing surface.

The Evoluent Vertical Mouse features 6 easily programmable buttons which can function differently in different programs. (Click on small photos above to view.) For example, you can program the same button to mean "double click" in one program and "back" in another.

The vertical mouse is sized to fit most people comfortably; your thumb opposes your finger action so the mouse doesn't move sideways when you click the buttons.
