It is comfortable to sit in your chair in a relaxed fashion and move freely.
The advice of some ergonomists is rather restrictive and will prevent such free movement.
HandShoe Mouse Field Research
During field research, the team of the HandShoe Mouse looked at all possibilities to allow the user of the mouse more freedom of movement. The patented bio-design of the HandShoe Mouse allows this without having to grip or pinch the mouse. Your muscles, however, need to feel some resistance to prevent unnecessary muscle action.
Through testing we established the optimal weight to work with and to allow your muscles to be as relaxed as possible. Hence we included some special counter weights. If you feel your mouse is too heavy, you can remove some weights. You will find them on the outside, under a special cover. (Watch the one minute video below)
Apart from weight control we advise to set your cursor speed at medium.
This minimizes the muscle strain required to control the cursor on the screen.
If your cursor speed is too high, some muscles which act in opposition will be unnecessarily strained.
So you know, the HandShoe Mouse is a balanced ergonomic tool!
