From The Register:

Google has been showing off the expected capabilities of the augmented reality spectacles that it is calling Project Glass.

The early concept designs show wire-framed glasses with a display above the right eye which shows off personal schedules and location-based information. Also included is a camera, a microphone for calls and voice recognition, a GPS, and (presumably) a wireless connector to make the whole thing work. The Chocolate Factory has set up a page on Google+ to get feedback and released a video about a ukulele-playing hipster to show how the glasses would likely work.
