What are the advantages and disadvantages of the mouse?
The mouse is our usual and familiar input device. It is easy to use and most people can use it very well. A classic mouse usually requires the working hand to rest in a horizontal position. In this position, the tendons of the arm get twisted. The constant movement necessary for clicking the mouse also causes a tiny tensing of the muscles. This can lead to excessive friction and strain in the arm, which can cause inflammation and tension.
But fortunately, there are some mouse alternatives which promote natural posture and thereby prevent RSI.
