The wearables market—activity trackers, smart watches, smart glasses, and embedded sensors in clothing—is exploding, and nowhere is that more evident than in the workplace. What was once viewed as more of a novelty now is becoming an integral part of both enterprises and smaller businesses. Why the newfound interest in business wearables, primarily smart glasses? For the same reasons IoT is taking over every sector—efficiency, enhanced productivity, safety, and significant cost savings. According to analysts, smart glasses have enabled the field services industry alone to achieve more than $1 billion in annual cost savings, propelling the market to $6 billion in sales in 2016.
