MIT PhD student and project lead Carrie Cai explained:

"With stand-alone apps, it can be inconvenient to have to separately open them up to do a learning task. WaitSuite is embedded directly into your existing tasks, so that you can easily learn without leaving what you were already doing."

Those are but two of the five tasks WaitSuite covers, though. One tool from the suite can look for Bluetooth iBeacons and will send you a flash card if it determines that you're in front of an elevator. Another will ask you to translate words while waiting for WiFi to connect, while the last one sends you words to translate while you're waiting for an email to send.

Based on the team's preliminary tests, some of the tools could prove more useful than others, depending on your situation. If your computer takes a while before it connects to WiFi, you can learn a word or two. Otherwise, that particular tool won't be that useful. Their testers seemed to love the elevator app, though, since it typically takes a minute to call an elevator and only 10 seconds to answer a flash card question.

Cai also noted that their testers were able to focus on their main tasks a lot better with the addition of the WaitSuite tools, since they were less likely to check Facebook and other social networks. In the future, Cai and her team want to create similar "wait-learning" tools in an audio format for times when you can't look at your screen. For now, you can test one of WaitSuite's apps available for download from the CSAIL website. The team made WaitChatter available as a Chrome extension for Google Chat, so you can learn words while waiting for a friend to finish typing.
