1. 调整椅子高度：确保双脚能平放在地面上，大腿与地面平行。 2. 背部挺直：保持头部、颈部和背部的自然曲线，避免过度弯曲或伸展。 3. 眼睛与屏幕保持一定距离：确保视线与屏幕中心线平行，避免长时间注视屏幕导致的视觉疲劳。 二、正确的键盘放置 1. 键盘边缘应与身体成一定角度：确保键盘边缘与肘部之间形成约30°的角度，这样可以减轻手腕的压力。 2. 键盘放置在正前方：将键盘放在身体正前方，避免手臂过度伸展或扭曲。 3. 调整键盘高度：根据个人习惯和舒适度调整键盘高度，确保打字时手部处于自然状态。 三、正确的击键姿势 1. 手指弯曲度适中：手指弯曲度应适中，不要过度弯曲或伸直，避免长时间打字时手指疲劳。 2. 指法准确：学习并使用正确的指法进行打字，有助于提高打字速度并减少错误。 3. 保持节奏：打字时注意保持适当的节奏，避免过度用力或过快打字导致手部疲劳。 四、适当的休息 长时间打字后，记得适当休息手部和眼睛。可以每隔一段时间进行简单的伸展运动，如转动手腕、伸展手臂等，以缓解肌肉疲劳。同时，也要记得定时休息眼睛，如进行眨眼运动、眺望远处等，以缓解眼部疲劳。 --- The Right Way to Use a Computer Keyboard - Have You Got It? In our daily lives, the keyboard has become an essential input tool, especially when using a computer. Prolonged incorrect usage can lead to a range of muscle and joint issues, such as wrist fatigue, finger pain, and cervical problems. Therefore, proper keyboard usage is crucial.
