A universal keyboard switch for a feeling test
Hiroaki Kosaka, Kazumasa Serizawa, Ikuo Watanabe · 2002
People sometime can recognize the quality of a computer keyboard by both the feel and/or sound of the key switches when they are pressed. For a good quality keyboard the switches when pressed, should have a feeling that is neither too heavy nor too light, and should also convey a clear confirmation of the switching being made. We focus on the man-machine interface of the keyboard and investigate the human feelings of touch and push, from the engineering point of view, in order to design switches that are comfortable to operate.>
