A YouTube video uploaded by the company shows Google Glass in action - including the interface which appears in the wearer's line of sight.
The search giant has also opened up the trial of the product to "creative individuals" and developers.
Google co-founder Sergey Brin was recently spotted on New York's subway testing the device.
The product was first unveiled as part of a demonstration at a Google launch event last year where developers were offered early access to the device for $1,500.
The company is now inviting people in the US to use the hashtag #ifihadglass to suggest ways they would make use of the headset. "We're looking for bold, creative individuals who want to join us and be a part of shaping the future of Glass," Google said.

The demo video showed how Glass can be used to take pictures and record video, as well as share content directly via email or social networks.
Voice commands such as "OK, Glass, take a picture" were used to control the device. Other features appeared to include Skype-like video chats, and other related information such as weather reports and map directions. All of this information appeared in a small, translucent square in the top right of the wearer's field of vision.
The display is considerably less intrusive than previously published concept videos.Wearable technology is seen as a major growth area for hardware makers in 2013 and beyond.
In 2008, Apple patented a laser based "head mounted display system" that it suggested could stream video from its iPod, among other features.
