先前人们遇到的问题是可穿戴的天线有时会碰到穿戴者的皮肤，或者是穿戴者可能走入某个建筑而远离最强的信号源。

Previously the problem was that a wearable antenna would sometimes touch a person's skin, or the wearer would walk into a building and turn away from the source of the strongest signal.

What you're much better at doing is saying how do I take the problem I've got and map it into a class of algorithms about which I know and use the efficiencies of those to try and figure out how to make it work.

当你碰到问题的时候,更好的方法是把遇到的问题映射,到已经设计好的算法中去,并用这些算法来提高效率,来保证问题得到解决。
