基本解释

The lack of tactile feedback is its undoing.
缺乏力反馈是它的弱点。
Without tactile feedback, typing on a touch screen is nearly impossible without looking at your fingers.
没有触感的回馈，你几乎无法不看着手指在触摸屏上输入。
As for the buttons, they provide good tactile feedback and make nary a sound -- all without feeling mushy.
而说到按键部分，它们提供良好的敲击回馈，几乎没有声音，而且没有软趴趴的感觉。

Pressing icons and buttons displayed on the touchscreen also gives tactile feedback.
