According to reports published in international media, the images show a minimalist design with a microphone and partly-transparent video screen that places information over the view from the users' right eye.
The product's developers say the report wanted feedback on the idea, but they did not give any indication about when the device might go on sale or what it would cost.
The members of project team said in a Google+ post, "We think technology should work for you, be there when you need it and get out of your way when you don't."
Stressing that the glasses were a concept far from being brought to market, Google wrote in a post, "We're sharing this information now because we want to start a conversation and learn from your valuable input."
"Images showed people wearing eyeglasses with silver frames that featured tiny cameras and on-lens displays to show information such as walking directions, weather forecasts or messages from friends," the report said, adding that a built-in microphone lets wearers instruct the internet-linked glasses by speaking.
The internet giant in a statement said, "We took a few design photos to show what this technology could look like and created a video to demonstrate what it might enable you to do," adding that "We took a few design photos to show what this technology could look like and created a video to demonstrate what it might enable you to do."
The film reportedly showed one user being reminded he has a date that evening when he looks up at a blank wall, and then warns him that there is a 10 per cent chance it will rain when he looks out of the window.
Google glasses warn the subway service is suspended. The video suggests that the device would involve a GPS chip to help deliver location specific alerts
An alert pops up when a friend sends a text asking if he wants to meet up later in the day. When the user dictates a reply a microphone symbol is superimposed over much of his view.
Other functions include Google Maps showing a route to the wearer's destination with small arrows keeping him on track, the ability to take a photo of what he is looking at with an option to share it with friends, and a video conference service.
There had been lots of speculation about the project with some reports describing it as an "open secret", but this is the first time Google has confirmed details of what it was working on.
The New York Times newspaper had previously suggested that the first set of glasses would go on sale before the end of the year for somewhere between $250-$600.
The report said that one Google insider said it was unclear when the glasses might be commercially available, but noted that the philosophy of Google was to develop technologies that could be used in a relatively short period of time, rather than dreaming up creations that won't be possible for 10 or more years.
Chris Green, principal technology analyst at Davies Murphy Group Europe, told the BBC that other tech firms such as Brother had attempted to pioneer the concept - but became unstuck because their versions had required users to carry separate processing and battery equipment that plugged into their glasses.
"There are huge opportunities for tailored advertising with augmented reality systems - especially if they have in-built GPS location tracking," Green said.
The glasses, under development for two years, will be tested in public by members of the Google team, according to the Google insider.
