Ergonomics is a technology born after the Second World War. In addition to our common styling design, ergonomics actually includes many aspects such as the location of buttons and the design of explanatory text.



In general, the so-called ergonomics, in essence, is to make the use of tools as suitable as possible for the natural shape of the human body, so that the person who can use the tools does not need any active adaptation to the body and spirit when working. Reduce fatigue caused by using tools. The ergonomic design of the mouse is mainly the design of the mouse. To study this problem, we must first study the natural structure of human hands.





Subject background

The use of computers and typewriters requires keyboard operations. Staff engaged in keyboard operations for a long time often cause fatigue in the wrists, arms, and shoulders, which affects work and rest. From an ergonomic point of view, in order to improve work efficiency and lasting operation, the operator should be able to adopt a comfortable and natural work posture. The staff adopts an abnormal posture due to the existing keyboard operating conditions, which causes the body The main cause of fatigue.


Ergonomic application

Because the keyboard is operated on the workbench, if the staff’s wrists are placed on the workbench, the wrists must be tilted up because the keyboard keys are higher than the workbench. Over time, it will cause wrist pain; while hanging the wrist or hanging the elbow Although the operation is more flexible, due to the lack of support in the hands, the muscles of the arms or shoulders have to be kept tense, so it cannot be sustained and is easy to fatigue. To this problem, the existing research conclusion of ergonomics is to maintain the natural angle of the cervical spine. On the other hand, the thickness of the front edge of the keyboard exceeds 50mm, which will cause the wrist to be overturned. The thickness should be kept at about 30mm, and a palm rest can be added if necessary. That is, it is solved by reducing the thickness of the keyboard itself and adding a hand support in front of the keyboard. The keyboard separated in the middle can make the user's hands and wrists more relaxed, in a natural state. This can prevent and effectively reduce the strain on the wrist muscles. The keys of this keyboard are at a comfortable angle for the user.


Ergonomics (or human factors) is the scientific discipline concerned with the understanding of interactions among humans and other elements of a system, and the profession that applies theory, principles, data and methods to design in order to optimize human well-being and overall system performance.

The Japanese National Railways researchers have been conducting repeated studies and comparisons on the design of the cab from the perspective of ergonomics, in order to create a reasonable design, easy to operate, and comfortable working environment for the driver as a guarantee for safe driving. 1. Monitor and analyze the visual situation of the driver. During the process of driving the locomotive, the driver must obtain various necessary information through the sense organs such as vision and hearing, and then analyze and judge them to determine the manipulation action. Most of the information is visual information obtained through the eyes of the driver, such as images, literature, images and so on.
