As AR technology has evolved and second and third generation AR devices come to market, the impact of AR in enterprise continues to flourish. In the "Harvard Business Review", Magid Abraham and Marco Annunziata discuss how AR devices are now being used to "boost workers' productivity on an array of tasks the first time they're used, even without prior training'. They contend that "these technologies increase productivity by making workers more skilled and efficient, and thus have the potential to yield both more economic growth and better jobs".
