Figure 1. OpenButterfly Protocol & Data Pipeline Illustration for both Pilot [A] and Revised [B] Studies. OpenButterfly Protocol indicates the general outline for each experimental session. As shown in Gameplay and Data Extraction, the HR, GSR, and EEG were independently collected for a baseline, and then collected with game data, motion capture, and video capture during gameplay. Our survey was administered at the end of each session. After each session, we compiled all the data files through synchronization achieved via Python. MATLAB R2018B [76] was used to run statistical analysis on biometric data, and OpenSim [31] utilized the tracking data to calculate shoulder joint kinematics and dynamics
