Extended reality (XR) devices such as the Meta Quest and Apple Vision Pro have seen a recent surge in attention, with motion tracking "telemetry" data lying at the core of nearly all XR and metaverse experiences. Researchers are just beginning to understand the implications of this data for security, privacy, usability, and more, but currently lack large-scale human motion datasets to study. The BOXRR-23 dataset contains 4,717,215 motion capture recordings, voluntarily submitted by 105,852 XR device users from over 50 countries. BOXRR-23 is over 200 times larger than the largest existing motion capture research dataset and uses a new, highly efficient purpose-built XR Open Recording (XROR) file format.

翻译：扩展现实（XR）设备（如Meta Quest和Apple Vision Pro）近期受到广泛关注，其中运动追踪"遥测"数据几乎是所有XR与元宇宙体验的核心。研究者们正开始认识到这类数据在安全性、隐私性、可用性等方面的深远影响，但目前仍缺乏大规模人体运动数据集用于研究。BOXRR-23数据集包含4,717,215条动作捕捉记录，由来自50多个国家的105,852名XR设备用户自愿提交。该数据集规模是现有最大动作捕捉研究数据集的200倍以上，并采用了一种新型、高效专用的XR开放录制（XROR）文件格式。
