| Abstract: |
| Using the theory of ergonomics, the keyboard design Is researched for the elderly. The mechanism motion model of the finger is established according to the physiological structure of the finger. Using the elderly hand size obtained measurement and statistics, the movement workspace of the elderly finger is obtained by the curve envelope method. The size and situation of the common key is designed according to the workspace. On this basis, the wrist rest is designed according to the relative situation of the finger and key. The overall shape of the keyboard is designed according to the bad posture using the existing keyboard. Finally, the layout of keyboard and keys are designed. It presents a computer keyboard design for the elderly. |
