Data acquisition. For each participant, time-series of 3D joint position data during the drinking task was acquired using both the computer vision system (CV) and a gold-standard marker-based motion capture system (MB-MoCap) (panel A). By post-processing this joint position data, relevant kinematic metrics could be obtained including a metric to quantify movement quality (panel B) and metrics to quantify movement compensation (panel C and panel D).
