Will Provancher, University of Utah (IMAGE) University of Utah Caption University of Utah mechanical engineer Will Provancher uses his right hand to demonstrate the Active Handrest he and his students developed to make it easier for doctors, artists, machinists, electronics repair people and others to operate, paint, fix equipment or do other work requiring precise hand movements. The device expands the so-called "dexterous workspace" -- the range over which you can move your fingers and be very precise. It does that by re-centering the hand repeatedly so the fingers are always in the right place to work precisely. Credit University of Utah.
