Summary:
Lieberman and Breazeal created a system to train human motor movements. Their hardware uses small vibrotactile actuators built into a sensory vest and sleeve. For each joint/sensor if the angle of the student's joint is different than the angle of the teacher (known) joint, then feedback is given to the joint. Higher errors increase the vibrating 'force field' effect.
To test their system, the authors had 40 subjects split into a pure visual group and a visual/haptic group. These subjects were given the task to mimic movements of a teacher. Overall, the error for the feedback group was much less than the error for the visual group, even after repeated trials.
Discussion:
Well written paper, clear subject manner, and a damn good results and evaluation section. I don't have much more to say than that.

At the time of this paper, I was slightly turned because it didn't seem directly related to the types of stuff we were doing in the class. Looking back at it, I agree that as a paper in general, it's pretty good. I hope our class has a chance to read a haptics paper of this depth and quality.
