Extended Reality (XR) is a comprehensive term that includes Augmented Reality (AR), Mixed Reality (MR), Virtual Reality (VR), and AI glasses. XR bridges physical and digital worlds, creating interactive, immersive experiences that merge with the real world. It offers numerous applications across education, training, manufacturing, collaborative 3D design, art, and multiplayer gaming.
Despite these benefits, XR systems introduce unique security, privacy, and trust challenges due to the intimate connection between users, their XR devices, and their immediate environments. The potential attacks can involve information flooding to induce latency and physical discomfort, injecting misleading virtual content to distract or deceive users, subverting personal area networks to create confusion, spoofing alarms, assessing user status through eye tracking, and accessing onboard cameras to gather environmental information without the user's awareness. Additionally, XR apps can access sensitive real-time inputs like eye gaze, head movement, hand gestures, and even biosignals, and users' immediate environment. These signals, while critical for immersive experiences, open up novel attack surfaces such as keystroke inference, emotional profiling, and behavioral tracking.
Le projet "Layers of Place: Austin" est une exposition en réalité augmentée accessible via l’application Hoverlay, composée de six installations disséminées dans le centre-ville d’Austin. Créée par le MIT Open Documentary Lab, cette œuvre mêle récits immersifs et histoire locale. Chaque installation, conçue par des artistes internationaux, explore des thèmes comme l’écologie, la mémoire ou l’histoire sociale. Les visiteurs peuvent découvrir ces œuvres gratuitement, même après la fin du festival SXSW, grâce à des QR codes sur place. L’objectif est de rendre l’art et l’histoire accessibles sans modifier physiquement les lieux.
