This study investigates the impact of the weight and centre of mass (COM) position of Head-Mounted Displays (HMDs) on the subjective evaluation of users during prolonged wearing tasks. This study involved 88 participants completing 1860 sets of experiments under three conditions: sitting still, turning the head, and moving, providing subjective evaluations of wearing HMDs. A static torque testing device was used to simulate neck torque under flexion states. Using Aligned Rank Transform (ART) data, A Multifactor Analysis of Variance (MANOVA) was conducted to analyse the relationship between subjective comfort and the weight and centre of mass (COM) of HMDs. Using cluster analysis to classify head length and identify the relationship between head length and comfort. A Support Vector Regression (SVR) model was ultimately established, providing detailed weight range references for the engineering design of HMDs.

This study explores the physical load effects of head-mounted displays (HMDs). By analysing subjective evaluations and torque data across five weight and centre-of-mass gradients, comfort thresholds were established and a predictive model was generated, providing weight balance references for HMD design.
