There hasn't been a lot of details on Google's Project Glass, but this time around, Google execs have gotten a little bit more talkative and eager to share more info on the tech. Product lead Steve Lee has given an interview to Fast Company on the project's origins and its future.

He confirmed that earlier prototypes were a bit bulky and that current prototypes are still "Very early". Lee does see photo-taking as a "key aspect" to the device, as well, on top of the "trackpad" feature we saw yesterday.

He also cast some doubt on initial reports that the devices would be available this year for between $250 and $600, saying that would be "pretty aggressive timing," but he also noted that he "wouldn't be on this project if it was like a five-year endeavor."

Contact lenses with that technology is a natural evolution he says, but a definite "long term thing" and that a nearer goal is to "serve everyone and make this a universal device".
