The VerticalMouse 4 is the latest generation of the well-known Evoluent mouse. The uniquely patented contoured design transforms the traditional palm down mousing position to a vertical handshake position which offers increased comfort for many users. A number of improvements were included in this 4th iteration including a larger flange along the bottom of the mouse to prevent the user's fifth finger from dragging on the desk. The thumb rest has been improved to provide even more comfort and reduced grip force requirements over earlier versions.

Performance based improvements include an easier-to-access pointer speed control button on the side of the mouse allowing the user to select between Extra Low, Low, Medium and High, giving users the ability to select the degree of precision they require for each task. An additional thumb button can also be assigned once a driver is installed.

The standard VerticalMouse 4 is available in both right and left-handed models, and comes in a dark grey housing with silver buttons. A small version of this mouse is also available only in a right handed model, and is easily distinguished as it has a black housing with purple buttons. If you are unsure which size of Evoluent VerticalMouse to get, these general guidelines should be useful:

Users over five feet and seven inches in height (> 5'7" [170 cm]) should order the regular-sized mouse (VM4R). Users under five feet and four inches in height (< 5'4" [162 cm]) should order the small-sized mouse (VM4S). For users between these two heights, either size of mouse may be suitable depending on other physical attributes - please call our toll-free number at 1 (866) 335-3746 for further assistance. [less]

The DXT Fingertip Mouse from City Ergonomics is an ergonomic vertical mouse designed to enable the hand and wrist to adopt a relaxed vertical posture. Control of the mouse is achieved by using the small muscles and joints of the fingers as opposed to the larger muscle groups of the shoulder and arm. The fingertips provide far more sensitivity, control and feedback than the arm which is why they are more suited for finer, precise movements requiring greater dexterity such as mousing. The unique design is also ambidextrous, allowing the user to easily balance the workload between the left and right hand.

The DXT Fingertip Mouse is ideal for those individuals who seek the precision and control afforded by a stylus, but in an ergonomic design which realizes that a pen and a mouse should not be designed with the same considerations. [less]

The Penguin Ambidextrous Vertical Mouse from Posturite allows the user to rest either hand comfortably alongside the vertical structure, encouraging the use of the bigger muscles in the forearm and upper arm to manoeuvre the mouse. Fine cursor control can be achieved with small hand and/or finger movements. Its ambidextrous design and central ‘bow-tie’ switch allow for easy transition between right and left handed use. Features include adjustable DPI (800, 1200, or 1600) and a precision scroll wheel. The Penguin is available in both a wired and wireless model, and in either small or standard size. To determine which size is most appropriate, measure the distance between the top of wrist and tip of middle finger - if it is above 18.0 cm, then select a standard model, if it is less than 18.0 cm, select a small model.

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. [less]

This is a wireless version of the popular Evoluent VerticalMouse 3. It uses a 2.4 GHz wireless method of transmission with a 30' range and estimated 3 month battery life. This wireless model features a fixed 1200 DPI optical sensor and has the same shape as the corded model. At present the wireless unit comes in a right-handed model only, with a black housing and smoke (dark silver) buttons, and comes in environmentally-friendly packaging. [less]

The Penclic Mouse from Penclic is an elegant precision mouse using a 'pen-shaft' design to make moving your cursor as easy as writing with a pen. Mouse buttons are on the pen-shaft for quick access, while there is a scroll wheel on the base. Available in wireless or corded models. [less]

The AirO2Bic Vertical Mouse is designed using the science of Biomechanics. The idea of the AirO2Bic is to immobilize your wrist and force you to use your upper arm muscles exclusively to move the mouse. To use this mouse properly you need a minimum of a 10" x 12" (25.4 cm x 30.5 cm) mousing area.

This product is available in both left and right handed models in both pearl (white) and onyx (black). The optional Nib software provides an auto-click feature, eliminating the need to 'click' the mouse, which is quite practical for web surfing and other non-cursor dependent tasks. The Nib software is $55 when purchased with this mouse and this bundle is called the Virtually Hands Free Mousing System. The Nib software is also available for $80 when purchased by itself.
