In April of 2012 Google announced an interesting project called Google Glass (or Project Glass). This became available to testers and developers in early 2013 for about $1500.
You tether them by Bluetooth to your smartphone for the connection. It currently has about 5 hours battery life on average usage as tested by Engadget. Many people are expressing serious concerns over privacy (bathrooms, movie theaters, bars) where people don’t know if you are recording them on video. There is no LED light blinking/on that would provide any indication. You can wear them over regular eye glasses. The focal point for the display is several feet in front of you.
“Google Glass is a wearable computer with an optical head-mounted display (OHMD) that is being developed by Google in the Project Glass research and development project, with the mission of producing a mass-market ubiquitous computer. Google Glass displays information in a smartphone-like hands-free format, that can interact with the Internet via natural language voice commands.”
