Within weeks of its last-month unveiling of `Google Glass' headset/eyewear device during the keynote at its I/O developer's conference in San Francisco, Google recently sent out emails to the Google Glass "explorers" - that is, people who had placed pre-orders for the device at the conference.

The email welcomed the Google Glass pre-orderers as "explorers," and also contained a copy of a Google+ post from the company's co-founder Sergey Brin. In addition, the correspondence - promising super secret updates on the progress of Google Glass project - also included a few instructions on how the pre-orderers could use their Google+ accounts for getting Google Glass-related private updates.

In the copy of the post accompanying the email - the Google+ post was earlier shared by Brin with Project Glass followers on the social network -, Brin said that Google was currently testing a new Glass feature which will be capable of automatically clicking photos after every 10 seconds.

Brin also said that he had the mode engaged when he was driving in Montana, and added that the Google Glass device had sent all the photos - clicked while he drove without any distraction - to his Google+ account through an instant upload.

Noting that Glass "allows you to enjoy and share life's moments without being tied down by technology," Brin - revealing Google's vision of the project - said: "We started Project Glass believing that, by bringing technology closer, we can get it more out of the way."
