The average person spends 10 to 15 minutes a day waiting for texts and instant-message (IM) replies, according to an analysis by Carrie Cai, a PhD student at MIT's Computer Science and Artificial Intelligence Lab (CSAIL).

据麻省理工学院计算机科学与人工智能实验室的一位博士研究生Carrie Cai调查发现，人们每天等待短信息回复的平均时间为10到15分钟。

What if you could be more productive during those idle moments? Cai is on the case.

如果能将这些闲散的时间利用起来做一些事情，会怎么样呢？Carrie Cai就在研究这个。
