Evaluating the impact of weight and center of mass on comfort in head-mounted displays

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.
