Muscular Stimulation for Haptic Modeling
Posted: Sun Mar 10, 2013 11:21 pm
At SXSW this weekend, Tech Crunch interviewed Olivier Bau, a Disney imageneer about his work:

The video starts off discussing electrostatic surface simulation, but then moves on to discussing Japanese research to use electrical stimulation to provide more substantial resistance.
A bit of googling uncovered this article, which might be the research that Baum is referencing:

It's an fascinating approach, which could be effective as a component of a haptic system. Since resistance would be created via active muscle stimulation, continuous operation would be impractical. However, I could see it used to provide resistance for hands or feet, where the use of an exoskeleton would be more cumbersome. Since the signal to contract can be detected about 100ms before contraction occurs, an active system could detect and predict hand and finger motions and then override the contraction signals as needed to simulate resistance.
