Effects of the Weight and Balance of Head-Mounted Displays on Physical Load

To maximize user experience in VR environments, optimizing the comfortability of head-mounted displays (HMDs) is essential. date, few studies have investigated fatigue induced by wearing commercially available HMDs. Here, we focus on effects HMD weight and balance physical load experienced user. We conducted an experiment which participants completed a shooting game while differently weighted balanced Afterwards, questionnaires to assess levels discomfort fatigue. The results clarify that affects fatigue, with degree varying depending center mass position. Additionally, they suggest torque at neck joint corresponds imparted HMD. Therefore, our provide valuable insights, demonstrating that, improve comfortability, it necessary consider both reduction during design.
