Toward Optimized VR/AR Ergonomics: Modeling and Predicting User Neck Muscle Contraction

Predicting the neck muscle contraction and discomfort levels of VR users. (a) A VR user chooses between two candidate head motion trajectories of seemingly similar muscular workload for a visual task. (b) Our computational model predicts the user's potential neck muscle contraction level and thus perceived neck muscle discomfort before the movements happen. 3D asset credits to Mixall, Bizulka, RootMotion at Unity, and shockwavegamez01, joseVG at Sketchfab.
