Inaccurate spatial tracking in prolonged actuality (XR) units leads to virtual object jitter, misalignment, and user discomfort, fundamentally limiting immersive experiences and natural interactions. In this work, we introduce a novel testbed that permits simultaneous, synchronized evaluation of a number of XR units below similar environmental and kinematic conditions. Leveraging this platform, we present the primary complete empirical benchmarking of 5 state-of-the-artwork XR units across 16 various situations. Our outcomes reveal substantial intra-gadget efficiency variation, iTagPro smart device with individual devices exhibiting as much as 101% will increase in error when operating in featureless environments. We additionally show that monitoring accuracy strongly correlates with visual situations and motion dynamics. Finally, we explore the feasibility of substituting a motion capture system with the Apple Vision Pro as a sensible floor iTagPro geofencing truth reference. 0.387), highlighting each its potential and its constraints for rigorous XR analysis. This work establishes the primary standardized framework for comparative XR monitoring analysis, offering the analysis neighborhood with reproducible methodologies, iTagPro geofencing complete benchmark datasets, and ItagPro open-supply tools that allow systematic analysis of tracking efficiency across gadgets and circumstances, thereby accelerating the event of more robust spatial sensing technologies for XR methods.

The speedy advancement of Extended Reality (XR) technologies has generated vital curiosity throughout analysis, improvement, and shopper domains. However, inherent limitations persist in visible-inertial odometry (VIO) and visual-inertial SLAM (VI-SLAM) implementations, particularly beneath challenging operational conditions together with excessive rotational velocities, low-gentle environments, and textureless areas. A rigorous quantitative evaluation of XR tracking programs is crucial for developers optimizing immersive applications and users deciding on units. However, three elementary challenges impede systematic performance evaluation throughout commercial XR platforms. Firstly, main XR manufacturers do not reveal critical monitoring performance metrics, sensor iTagPro geofencing (monitoring digicam and IMU) interfaces, iTagPro support or algorithm architectures. This lack of transparency prevents unbiased validation of tracking reliability and limits determination-making by developers and finish users alike. Thirdly, current evaluations concentrate on trajectory-degree performance however omit correlation analyses at timestamp level that link pose errors to digicam and IMU sensor data. This omission limits the ability to analyze how environmental components and person kinematics affect estimation accuracy.

Finally, most prior work does not share testbed designs or experimental datasets, limiting reproducibility, validation, and smart item locator subsequent research, comparable to efforts to mannequin, predict, or adapt to pose errors based on trajectory and sensor knowledge. In this work, we suggest a novel XR spatial monitoring testbed that addresses all the aforementioned challenges. The testbed permits the following functionalities: (1) synchronized multi-device tracking efficiency analysis beneath various movement patterns and configurable environmental conditions; (2) quantitative evaluation among environmental characteristics, consumer motion dynamics, multi-modal sensor knowledge, and iTagPro features pose errors; and (3) open-source calibration procedures, knowledge assortment frameworks, and analytical pipelines. Furthermore, our evaluation reveal that the Apple Vision Pro’s monitoring accuracy (with an average relative pose error (RPE) of 0.Fifty two cm, which is the perfect amongst all) permits its use as a floor fact reference for evaluating other devices’ RPE with out the use of a motion seize system. Evaluation to promote reproducibility and standardized evaluation within the XR analysis neighborhood. Designed a novel testbed enabling simultaneous analysis of a number of XR devices below the same environmental and kinematic situations.

This testbed achieves accurate evaluation via time synchronization precision and extrinsic calibration. Conducted the primary comparative evaluation of 5 SOTA industrial XR devices (four headsets and one pair of glasses), quantifying spatial tracking efficiency throughout sixteen numerous eventualities. Our evaluation reveals that common tracking errors range by up to 2.8× between units beneath identical difficult circumstances, with errors ranging from sub-centimeter to over 10 cm relying on units, movement varieties, and atmosphere circumstances. Performed correlation analysis on collected sensor information to quantify the impression of environmental visual options, SLAM inside standing, and IMU measurements on pose error, demonstrating that different XR gadgets exhibit distinct sensitivities to those elements. Presented a case study evaluating the feasibility of utilizing Apple Vision Pro as an alternative for traditional movement seize techniques in tracking analysis. 0.387), this means that Apple Vision Pro supplies a reliable reference for local monitoring accuracy, making it a practical instrument for many XR evaluation situations regardless of its limitations in assessing world pose precision.
