In these tough times, industrial and logistics environments need to maximize workplace productivity and safety to contain costs while satisfying customers. Increasingly, warehouse operators are discovering that hands-free devices are an effective solution to accomplish these goals. Wearable and voice-enabled mobile computers make warehouse operations hands-free, eliminating time spent picking up and reholstering handheld computers. Interacting with mobile computers using voice also make processes eyes-free, so the worker never loses sight of the task at hand. Together the two can boost productivity in the warehouse by as much as 20%.
