报告摘要 Abstract：

近年来，扩展现实（XR）系统将虚拟现实（VR）、增强现实（AR）、人工智能（AI）、数字孪生（DT）以及物联网等技术深度融合，催生了大量基于Meta Quest、MS Hololens、Sony PlayStation VR、字节跳动Pico和 Apple Vision Pro等多样化VR/AR设备的扩展现实应用。与此同时，涵盖游戏、医疗健康、工业制造、创作者经济与数字艺术等领域的多元化扩展现实应用也相继涌现。然而，由于系统固有的复杂性与异构性，当前扩展现实发展仍处于早期阶段，这导致其难以建立有效的安全防护机制。此外，新兴的安全漏洞与隐私泄露风险也阻碍了扩展现实系统的广泛普及。本次讲座将首先概述扩展现实系统及相关技术的最新进展，进而深入剖析其面临的挑战与潜在解决方案，随后汇报研究团队取得的系列前沿成果，最后展望这一潜力领域未来的发展方向。

The recent advent of extended reality (XR) systems with the synergy of virtual reality (VR), augmented reality (AR), artificial intelligence (AI), digital twin (DT), and the Internet of Things has proliferated a number of XR applications (apps) on top of diverse VR/AR devices, such as Meta Quest, MS Hololens, Sony PlayStation VR, ByteDance Pico, and Apple Vision Pro. Meanwhile, diverse XR applications have emerged, such as gaming, healthcare, industry, creator economy, and digital arts. However, the current development of XR systems is still in the early stage because of their intrinsic complexity and heterogeneity, which hinders effective security protection. Moreover, emerging security vulnerabilities and privacy-leakage concerns have also prevented XR systems from wide adoption. In this talk, I will first briefly review recent advances of XR systems as well as relevant technologies. I will then elaborate on its challenges as well as potential solutions. Next, I will report several progressive research achievements from my research groups. Finally, I will discuss several future directions in this promising area.
