Abstract: A computer-implemented method is provided for coordinating sensed poses associated with real-time movement of a first object in a live video feed, and pre-recorded poses associated with movement of a second object in a video. The computer-implemented method comprises applying a matching function to determine a match between a point of one of the sensed poses and a corresponding point of the pre-recorded poses, and based on the match, determining a playtime and outputting at least one frame of the video associated with the second object for the playtime.

Abstract: Example implementations described herein are directed to systems and methods for skill assessment, such as hand washing compliance in hospitals, or assembling products in factories. Example implementations involve body part tracking (e.g., hands), skeleton tracking and deep neural networks to detect and recognize sub-tasks and to assess the skill on each sub-task. Furthermore, the order of the sub-tasks is checked for correctness. Beyond monitoring individual users, example implementations can be used for analyzing and improving workflow designs with multiple sub-tasks.
