When most of us think of augmented reality, thanks to Google, we think of dorky glasses with an ugly camera mounted on the frame. But what about the other senses? What if all of them were augmented and all those augmentations worked in concert?

That broader view of AR might be closer to what tech companies will be unveiling in the next couple of years. Humans take in enormous amounts of sensory input every second. We make judgements about threats, reactions, choices and pleasures from subtle and dramatic changes in the patina of inputs we're swaddled in. 

Some decisions are made on minuscule cues -- a wink, a flicker at the periphery of vision, a rough burr on a flat surface, a chirp.
