中文摘要:

      目的 应用人机工程学理论研究设计适用于老年人使用的键盘。方法 根据手指的生理结构构建手指按键的机构运动模型；利用测量统计得到老年人手的尺寸，应用曲线包络面法得到老年人手指按键的运动轨迹范围，根据该范围得到常用键的区域大小，根据手指和所选键面的相对位置对腕托进行相应设计；根据现有键盘在使用中的不良姿态，对键盘进行总体造型设计；对按键和键盘布局进行设计。结论 提出了适合老年人使用的计算机键盘设计方案。

英文摘要:

      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.
