Proprioceptive Misestimation of Hand Speed
The accuracy with which the human proprioceptive system estimates hand speed is not well understood. To investigate this, we designed an experiment using hobby-grade mechatronics parts and integrated it as a laboratory exercise in a large remote laboratory course. In a simple joint position reproduction task, participants (N = 191) grasped a servomotor-driven shaft with one hand as it followed a randomized trajectory composed of sinusoidal submovements. They simultaneously attempted to reproduc…
