๐ฏ What it does: This study collects synchronized data of neck muscle contraction levels (MCL) and head motion (posture and acceleration) by using surface electromyography (EMG) sensors on VR headset wearers. Based on this data, a biophysical model (MCLNet) is constructed to estimate the MCL of completed head movements. Subsequently, TrajectoryNet is used to regress typical motion trajectories between initial and end postures, further predicting the MCL before the head movement begins, thereby assessing the user's potential neck discomfort in advance.
