Evolution of the Mouse

evolution of computer mouse

Several years ago we only had the conventional mouse.
With this standard mouse, the hand has no other option but to grip and pinch the body in order to move the mouse, often from the wrist. Hand and fingers hover above the mouse buttons to prevent inadvertent clicking.

Then, there was the vertical mouse which was meant to be an alternative to the standard mouse, creating a better mobility. New university research showed, however, that any vertical position forces your hand in a handshake position. This results in significant stresses on the interosseous membrane in your forearm, which connects ulna and radius. It also affects your thumb and finger muscles. Due to the vertical, handshake position, gripping and pinching is still required, to handle the mouse.

The truly ergonomic HandShoe Mouse is the next step in the evolution of the mouse.
It was designed by a medical university and created to counter all the negative effects.
It supports your fingers, hand palm and wrist under an ideal slanted angle.

In this position the interosseous membrane is fully relaxed and there’s no more gripping and pinching!

In this one mintue video we show you the details of the evolution of the mouse:

Ergonomic Mouse: New Left HandShoe Mouse

The truly ergonomic HandShoe Mouse is now offering a brand new ergonomic mouse for the left hand in sizes Small, Medium and Large. This ergonomic mouse also has a reduced click force for the mouse buttons which makes the user experience even better. Available at the end of September 2011.

Ergonomic Mouse in Three Sizes

HandShoe Mouse LeftHippus, the owner and producer of the patented, truly ergonomic mouse,the HandShoe Mouse, is pleased to introduce the new version for the left hand. This new ergonomic mouse model will be mass produced in sizes Small, Medium, Large and comes with a lighter “click force” to operate the mouse buttons.

This will give the user a very comfortable ergonomic experience. Later this year the lighter”click force” will also be made available for the right hand version.

Until recently the left hander was only available as a handmade mouse at considerable higher costs but with the larger production volume the left hand version is now available at a price comparable to the right hand version of the HandShoe Mouse.

The unique patented shape of the HandShoe Mouse is based on many years of research and testing by several medical universities.

Ergonomic Mouse Features

The most important features of the HandShoe Mouse are:

  1. full support of you hand and fingers at the proven ideal angle of 25-30 degrees
  2. no possibility for “gripping and pinching”, a major cause for RSI and Carpal Tunnel Syndrome
  3. no friction between the skin of your hand and the desk top

Latest Research: Vertical Mouse Needs Re-evalution

When people are talking about the best ergonomic mouse, we frequently hear remarks about the so called “Handshake” position, alleged to be the most natural and relaxed. This statement is then substantiated by means of a picture or video in which a skeleton is used.
To our judgment this is an aberration, for, we as human beings can only act and do as we do because of physical functions for which we need muscles, tendons, blood, arteries, veins, nerves etc. By leaving out these higly significant elements of the acting human body, one gets a most unrealistic if not ridiculous impression.

Continuing Ergonomic Research

At both Erasmus (Rotterdam, Netherlands) and Hasselt (Belgium) University Medical Centers, highly educated researchers continue to study the human body, based on corpses, to simulate the situation in a working environment. This has also taken place for the position of forearm and hand while operating a computer mouse.

The first point to be made is that there is a fibrous sheet (membrane) which connects the 2 bones (Ulna and Radius) of the forearm. Rotating the forearm like when you put your hand on the desktop has a significant effect on this membrane. Next to this phenomenon one should not forget that a number of muscles which control the fingers are connected to this membrane.
In studies, the behaviour of this membrane has been looked at to establish the effects of for example a position like the “handshake”.

Truly neutral hand position on an ergonomic mouse is not vertical but slanted

Recent research by Professor K.J. van Zwieten and his team of the University of Hasselt (Belgium), demonstrated that the Handshake position results in a maximally taut membrane between the 2 bones, Ulna and Radius. Therefore the need to grip and pinch a mouse in a Handshake position, for example with a vertical mouse results in unnecessary strains in the already taut membrane. This could possibly result in physical complaints. In two publications, the resesarchers have stated that the use of a vertical PC-mouse in Handshake positions should therefore be re-evaluated.(see publication 1 and publication 2)

The studies with regard to the design of the computer mouse by Professor Han Ming Chen of National Taiwan University and Professor Snijders of Erasamus University Medical Center are of significant interest.
Erasmus University has already shown that the ElectroMyoGram (EMG) measurements of a vertical mouse show a continuous activity without any moment of rest, just like a standard computer mouse.

This, among others, is the result of the reaction force of the thumb with respect to the fingers, not only due to holding the mouse (gripping and pinching) but even more when switching.
By means of EMG measurements it is shown that a slightly slanted mouse body (like the HandShoe Mouse) prevents the above mentioned unnecessary tensions.

One must therefore assume that the truly neutral hand position on an ergonomic mouse is not vertical but slanted.
