AB - This study empirically analyzed positional accuracy based on a ‘smart HMD hub’ system that manages tracking data from each terminal and synchronizes the existing coordinate system in real time to solve the problem of positional mismatch in virtual-reality space that occurs in a multi-user HMD-based VR environment. An environment was created in which eight simultaneous users could move freely in a 227.02㎡ space, and based on the ‘Smart HMD Hub’ system, the physical movement distance and virtual space coordinate values of the Inside-Out Tracking HMD were precisely measured to calculate the position error distance. The measurement results showed that the average positional error between virtual and reality was 19.2 mm, demonstrating high accuracy below 2 cm, a visual threshold difficult for users to perceive. The error fluctuated stably within a maximum of 32 mm instead of drifting in proportion to the movement distance, confirming that the system effectively compensates and synchronizes the coordinate systems of multiple HMDs. In addition, the system performance was confirmed to maintain a stable frame rate of 82.04 fps on average even when 8 users were connected simultaneously.
