The Anir™ Vertical mouse is truly ergonomic tried and scientifically tested. Different from other mice on the market, it looks like a pilot stick. Users rest the back of the hand at the base of the mouse and the thumb on the switch on the top of the stick for easy right and left clicks of the mouse button.
Designed as a pilot stick, the mouse encourages a natural vertical hand position with the thumb pointing upwards.
Traditional mouse designs mean that you have to twist your forearm to put the palm of your hand in a horizontal position over the mouse. This pronation is not a relaxed position.
Right/left mouse button
The cursor is controlled with your thumb in a natural resting position.
Traditional mouse designs mean that you have to bend your hand slightly upwards with the wrist extended. This extension and the pronation of the forearm result in a heavy muscle load.
Middle button / scroll button
The middle button is operated by squeezing your middle fingers. This button can be used for document scrolling in many applications under Microsofttm Windows XP and 2000.
The mouse comes in two different sizes. Click here to learn more about how to pick the right size for your hand. Unfortunately there is currently no left hand version available.
The mouse uses optical sensors for very precise and accurate reading of the mouse motion.

A study was carried out to compare Anir™ Vertical mouse with a traditional mouse. Electromyography (EMG) was used to record the muscle load on the extensor pollicis longus, extensor digitorum communis and trapezius muscles. The muscle load on the forearm proved significantly lower with Anir™ Vertical mouse than with the traditional model. This was also true for the extensor pollicis longus for the static (p=0.0005) and median (p=0.001) values of the amplitude distribution function (ADF) and the number of occasions per minute when the muscle load was below 1% MVC (Maximum Volume Contraction) (p=0.03).
The same clear trend was also found for the static muscle load from the extensor digitorum communis (p=0.06).
A reduction in muscle load is thought to play an important role in the prevention of pain in the musculoskeletal system.
Anir™ Vertical mouse involves only slight flexion of the wrist and slight pronation of the hand which results in low pressure in the carpal tunnel. This pressure may be a key factor in the development of carpal tunnel syndrome (CTS). In the USA alone, estimates put the cost of “mouse injuries” at USD 7 billion.
It will therefore be vital to design products which can reduce and prevent injuries caused by using the wrong mouse!
It takes about three days to get accustomed to the Anir™ Vertical mouse. By then you will have discovered the truth of our claim: Not only ergonomic, but better to use.
