The shape of the keyboard is divided into a standard keyboard and an ergonomic keyboard. The ergonomic keyboard is to separate the left-hand key area and the right-hand key area according to fingering on the standard keyboard, and form a certain angle, so that the operator does not need to be conscious. It clamps both arms and maintains a more natural shape. The keyboard with this design is named by Microsoft as the Natural Keyboard. For users who are used to touch typing, it can effectively reduce the mis-hit rate of the left and right-hand key areas, such as letters. “G” and “H”. Some ergonomic keyboards also intentionally increase the area of commonly used keys such as the space bar and the enter key, and add a hand guard plate to the lower part of the keyboard to support the previously suspended wrist and reduce the fatigue caused by the long-term suspension of the wrist. These can be regarded as humanized design.
