So virtual keyboards don't necessarily have to emulate today's electromechanical keyboards in every respect. For example, Hill says, "there's an ergonomic improvement with shorter travel because you can type faster," ***but only to a point***. While fingers striking a solid glass surface offer no travel at all -- not very good for touch typing -- virtual keyboards don't have to emulate the long travel of the previous generation of keyboards to offer acceptable performance.
所以，虚拟键盘不一定非得在各方面模仿今天的机电键盘。比如说，Hill说：“可以使用更短的行程，以求人机工程学方面有所改进，因为那样你可以打得更快，”***不过得有个度***。
