台式电脑的键盘让你能够在打字时把双手放置在桌面上休息,但是例如平板电脑上的触摸式键盘则无法提供这种优待。这种键盘要求你的手指远离屏幕,避免不小心触碰到屏幕其他部分。为了做到这个动作,支撑你手臂的上背部肌肉需要保持活跃,这是使用普通键盘时不存在的问题。根据发表在《华尔街日报》的研究报告,长此以往,这个动作可能导致慢性肩部问题。此外研究者发现,利用触摸屏打字的平均速度只有键盘打字速度的一半。

Hovering Over a Touch-Screen Keyboard Has Its Consequences

Desktop-computer keyboards allow you to rest your hands on the keys as you type, but touch-screen keyboards, such as on many tablets, are less forgiving: They require you to keep your fingertips off the screen to avoid accidentally activating the keys. Thus the upper-back muscles that support your arms are more active when you type on a touch screen than when you use a standard keyboard, which could lead to chronic shoulder problems, according to research reported in the Wall Street Journal. The average typing speed on touch screens is also less than half that on desktop keyboards, the researchers found.
