Proprioception conveys haptic information and is important for stroke recovery, but there are few easy-to-deploy technologies for assessing it. Our goal here was to develop a method to quantify arm proprioception using a web cam. The basic idea is to require participants to use one hand to point to a randomly chosen finger on their other hand, which is obscured using augmented reality. Proprioceptive acuity is quantified via computer vision as pointing error. We show that pointing error depends on availability of proprioceptive input from the target hand, that obscuring the hand is as effective as blindfolding, and that we can reliably quantify pointing error. #haptics #haptics2024
