You’ve heard of whistle while you work, but how about sniffing while you steer? Engineers in Israel have created a gizmo that allows paraplegics and quadriplegics to navigate their motorized wheelchairs simply by using their breath. One sniff sends you forward, two sniffs sends you back, and so forth. A computer translates the air breathed into a sniff controller and produces a corresponding movement to the wheelchair’s motor. Big ups to Anton Plotkin and his homies at the Weizmann Institute of Science in Israel for this amazing advance. Distributed by Tubemogul.
