Keyboard ergonomics, also known as ergonomics or ergonomics, is a new discipline developed after the Second World War.

Specific to the product, that is, the design and manufacture of the product are completely tailored according to the physiological and anatomical functions of the human body, which is more conducive to the physical and mental health of the human body. The ergonomic keyboard divides the ordinary keyboard into two parts, which are unfolded at a certain angle to adapt to the angle of human hands. Users don't have to bend their wrists, which can also effectively reduce wrist fatigue.
