Emotient has become the latest startup to get scooped up by Apple, and it’s one of the more interesting ones we’ve seen. The San Diego-based startup specializes in using people’s facial expressions to determine their emotions, and prior to its acquisition by Apple, it was reportedly experimenting with combining reaction analysis with advertising. Now that Apple owns the company, however, we have no idea what it’s going to be doing in the future, and as usual, Apple is remaining very tight-lipped about the acquisitions and it plans for the company.
