Google GLASS is already a pretty awesome device. Developers come up with cool solutions for it all the time. Researchers at the Georgia Institute of Technology have come up with Captioning on Glass, a technology that uses an Android app to allow the GLASS wearer to see what the other person is saying in a conversation. It relies on speech to text conversion to get the job done. The text shows up on GLASS and is displayed on the heads-up display. This could be useful for folks who have hearing issues.
