Wearable technology coming quickly

Google glasses were just the start of the wearable technology explosion getting ready to happen...even this year. Americans have used wearable technology for generations in the form of pocket watches, wrist watches, compasses, hearing aids, etc. Last year, wearable technology was estimated at $9 billion and projected to reach $30 billion by 2018. Georgia Tech Professor Thad Starner made this observation about wearable technology..." We're talking about paradigm changing devices, capabilities people haven't thought of before. Unlike computers and tablets, wearables are designed to operate in the background secondary to the wearer's attention."
