It focuses on designing adaptive, human-centered XR environments that incorporate speech, gesture, gaze, and haptics for seamless interaction. Main topics include personalization, accessibility, cognitive load, trust, and ethics in AI-driven XR experiences. Through presentations, discussions, and collaborative sessions, the workshop aims to establish a subcommunity within IUI to develop a roadmap that includes design principles and methodologies for inclusive and adaptive intelligent interfaces, enhancing human capabilities across various domains, such as healthcare, education, and collaborative environments. More information can be found here: https://shapexr.icar.cnr.it/ TOPICS ---------- The list of topics includes (but it is not limited to) the following: - AI-driven real-time personalization of immersive interfaces based on user states, contexts, and goals in XR environments. - Multimodal interaction (speech, gesture, gaze, haptics) with AI agents. - Cognitive load, trust, ethics, and emotional engagement in AI-powered XR. - Accessibility and inclusivity in immersive AI systems. - Evaluation methods for human-centered XR and AI interfaces. - Social and collaborative AI-enhanced XR experiences. - Design principles and methodologies for adaptive intelligent interfaces. - Applications of XR-AI interfaces in healthcare, education, work, or entertainment.
