Google's Sergey Brin made a surprise appearance at the TED conference for ten minutes this morning, showing off Google Glass before a live audience of attendees and many others watching via livestream. He confirmed that Glass would ship later this year, but also offered insight into why Google is so committed to the project.

"I feel it's kind of emasculating."

Brin began the talk by looking down at his phone, and commenting that, like many, this is how he spends most of his time. "We often question if this is the way you want to connect with the people in your life," Brin said. "I feel it's kind of emasculating. You're just rubbing this featureless piece of glass." This featureless touch, Brin claimed, is why his wife still uses a Blackberry.

The goal for Google Glass was to create a less secluded way of interacting with the same interaction. As Brin put it, "The cellphone is a nervous habit. I whip this out and look as if I have something important to do. [Google Glass] takes that away."

Brin also took questions from Chris Anderson on recent eBay listings that promised a Google Glass for up to $15,000, Brin said, "I wouldn't trust those eBay posts." For the real thing, we'll have to wait.
