I remember a time when the AR news was not about consumer products and was read in little pockets of the internet and amongst "Kit" obsessed übergeeks who strapped cameras to their heads and wore "wearable computers" which, at the time, were backpacks with pcs in them. They wanted to show everyone how cool it was, but your average person, is unwilling to wear a backpack computer with a camera on a bike helmet and walk into a public place anywhere.
