When you enter GetVu’s office in Bengaluru, you are likely to find people wearing weird looking glasses and trying to grasp something from thin air. A few others are wired to their computers oblivious to their surroundings. Looking a lot like the Facebook Oculus Rift, their glass product is called PikVu, which the three co-founders have developed using augmented reality (AR). It is now being used in warehouses to improve the efficiency of the workers by almost 25%. Its second product, RemoteVu, enables a service engineer to view faulty machinery from a remote location. It was one of those things that the 20-somethings did for fun and eventually turned into a phenomenon.
