Microsoft’s HoloLens mall demos bring early AR glasses to the masses

Your phone or tablet might already have augmented reality capabilities, but the concept of AR doesn’t mean much to the average person right now: Apart from a couple of games and apps, AR is far from mainstream. Surprisingly, Microsoft is taking steps to change that, as it recently added HoloLens AR headset demos to its retail stores, letting mall shoppers go hands-on with a potentially transformative technology.I say “potentially” because many companies — Microsoft, Google, and Apple among them — expect that augmented reality is going to be a big deal some day, but the hardware is currently stuck in a rut. As I explained last month, the key problem is that there’s no affordable, wearable hardware in the marketplace. HoloLens is wearable, but at $3,000 or more per headset, it’s not affordable. On the other hand, Apple and Google sell affordable AR devices, but none of them are wearable.
