Emanating from the same Google think-tank that is developing self-driven cars, the "augmented reality" glasses can snap photos, initiate videochats and display directions at the sound of a user's voice.
The Google+ page features a 150-seconds video, shot from the perspective of someone wearing the glasses. The posting is intended to show "what this technology could look like," the company said.
The specs almost certainly pave the way for Google to more closely integrate its ad-supported online services into people's daily lives, in example web searches, maps and email.
More to the point, they could also help Google match some of the buzz that rival Apple has generated with the latest iPhone, and its built-in Siri digital assistant which reacts to spoken commands such as 'schedule calendar appointments' and 'get weather forecasts'.
It's unclear when the glasses might be commercially available, but observers note that Google's general commercial philosophy is to develop technologies that can be monetized in a relatively short period of time, as opposed to projects that that won't be go to market for ten or more years.
