Originally, the company limited preorders to those who attended Google I/O last year that wanted to opt-in to the smartglasses. The new expansion opens preorders to "bold, creative individuals who want to join us and be a part of shaping the future of Glass." However, it's not as simple as entering your information in a form.
Instead, if you want to be a "Glass Explorer," you have to tell Google -- via Twitter or Google+ -- what you would do if you had "Glass" in your hot little hands. Entries must be limited to 50 words or less, though since you are also limited to 140 characters on Twitter, we'd recommend tweetmore or some analogous Twitter message extension service.
You need to included the hashtag #ifihadglass, and you can also add up to five photos and a 15 second video. To ensure that Google can contact you if you are chosen to be an "Explorer," you must follow Project Glass on Google+ (+ProjectGlass) or Twitter (@projectglass).
You must be at least 18 years old and live in the U.S. to apply
The deadline for applications is Feb. 27, which doesn't give you much time, so get creative, now. Those chosen will be contacted by Google with an invitation to become a Glass Explorer.
There's more expense involved, too. You will need to preorder a Glass Explorer Edition device for $1,500 + tax, as well as agree to attend a special pick-up experience, in person -- no shipping, since that would lead to possible lost packages and therefore, lost Google IP -- in New York, San Francisco or Los Angeles.
The entries will be judged by an independent jury. Applications will be scored on creativity, originality, usefulness, and how compelling and influential the applications and their proposed uses for Glass are, and how broad a spectrum of user interaction the entry would provide.
Google will be contacting winners in mid-to-late March through direct messages on Google+ and Twitter. Each person can enter up to three times.
