With ergonomic design mouse you get tired of stiff shoulders and arms

The Fukuda laboratory at Keio University SFC Institute (Shonan Fujisawa Campus) conducted a research focusing on the mouse product of ergonomics design by Microsoft, and as a result of the first experiment, the evaluator gave " "Products that allow usability to be realized over time" "A stiff shoulder while using, a feeling of tiredness of the arm has ceased to be felt" was obtained about the physical sensation.

As a result of carrying out further limited verification experiments from this result, it seems that it turned out that it was "a mouse that knows better enough to use".

Details such as how to hold the correct mouse are as follows.
Fukuda laboratory of Keio University SFC Institute (Shonan Fujisawa Campus) attention to mouse ergonomic design mouse products of Microsoft

Product used this time is "Microsoft Natural Wireless Laser Mouse 6000 (Microsoft Natural Wireless Laser Mouse 6000)It is a mouse of this form.


It seems that the Fukuda laboratory seems to be able to find the potential advantage of ergonomic design "aiming at reducing fatigue". Despite having a distinctive shape different from that of a conventional mouse, not only is it compatible with the feeling of use that boosts with the familiarity of conventional mice but this musical mouse is easier to use depending on the person He said that he was improved until he felt that he was feeling.

In addition, this fact is also known from the result that no significant difference was observed with the measurement value of the eye movements using different mice, and in the subjective evaluation by the continuous use for a certain period of time, "the mouse that knows better enough" Evaluation result.

This is the experimental landscape of eye movement measurement


This is a subjective assessment for Natural Mouse (comparison by usage experience). Evaluation after one week's use by the experienced person is the highest, then the experienced, the novice in turn.


So this is the way to hold the correct ergonomic design mouse. Attach hands from the side with the elbow as the axis.


What kind of reasoning and how much "fatigue alleviation degree" appears will be considered for future study. Among them, fatigue alleviation degree may be digitized and it may become apparent by each individual mouse and keyboard.

Incidentally, Fukuda laboratory led the contents and method of this experiment, and the experiment result led by the Fukuda laboratory, except for the loan of the sample mouse for evaluation except for Microsoft's tampering with information, fabrication and transfer of money such as research expenses etc. There seems to be nothing.
