There was an impressive demo at the Fujitsu booth showing how a maintenance engineer could observe and adjust flow rates in pipe and valves and make sure they were operating properly and even make adjustments to controls. Smart Glasses from Vuzix were coupled to a "smart gesture" glove to put the engineer in control of a number of complex operations.

it was quite an impressive demo from the Augmented Reality perspective, but I'm hoping that the technologically impressive, but somewhat cumbersome "glove" will be replaced with hand gestures and voice command recognition in the near future.
