Today Google unveiled a YouTube video teasing its augmented reality eyeglasses, a pair of spectacles that interacts with what you’re seeing and acts as a smartphone, day planner, turn-by-turn navigation system, camera and more.

The glasses run a form of Google’s Android operating system that appears to be both voice-controlled and, less familiarly, view-controlled: A bar of small icons floats just above the wearer’s line of sight, and by looking upward, the wearer can interact with the icons to view the weather, send text messages, and do much of what a smartphone can do. In addition to smartphone functionality, however, the Google glasses attempt to interact with the world that it sees in front of and around the wearer, “augmenting” or supplementing the reality that the wearer experiences.
