HapticWe have been curious to understand why people tune the hand when they explore objects. Tuning involves variation of antagonistic muscle co-contraction, posture, and shape of the limbs. Intuitively, we can predict that these conditioning behaviors changes the way external forces are projected across different sensors in the body to extract different features in the stimulus. Here are some of our publications in this area:
