New details about Google’s eagerly-anticipated smart glasses have been released by the company in a YouTube video.

How It Feels 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.

“We’re still in the early stages and, while we can’t promise everything will be perfect, we can promise it will be exciting.”

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.

Other patents obtained by Sony and Microsoft allow for creation of miniature displays to go over users’ eyes.

Oakley recently launched Airwave – ski goggles with built-in sensors which provide information on an in-built screen about an owner’s speed, the size of their jumps and what music they are listening to.

Away from the head, the newly released Pebble watch links directly to a smartphone – a concept Apple is also rumored to be working on.
