You may have heard that later this year, Google are planning to release smart spectacles that will project information, entertainment and advertising onto the lenses for the wearer to see. If you want to know the time, the temperature, talk to a friend or get directions to that cafe you read about in a magazine, it will all appear as if by magic in front of you. To watch a video showing you how this will work, click here. Also linked to the Google Goggles project and available now is an app for iPhone and Android that allows you to point your phone's camera at almost anything and instantly receive information from the Internet about what it is looking at. Point your phone at a bottle of wine and it'll tell you where you can buy it, how the critics rate it and which region of France it comes from. You can find the download here along with a detailed explanation of how it all works.
