The Future of Interaction: Unlocking the Potential of Multimodal XR with AI and LLMs
The world of Extended Reality (XR) is rapidly evolving, and at the heart of this transformation lies the quest for more natural and immersive human-computer interaction. A recent comprehensive review by a team of researchers led by Feng Lu has shed light on the latest advancements in multimodal natural interaction techniques for XR headsets, offering valuable insights into how AI and large language models (LLMs) are revolutionizing user experiences.
The review, published in the prestigious Frontiers of Computer Science on December 15, 2025, analyzed 104 papers published since 2022 across six top venues. It highlights the growing importance of spatial computing technologies, which are becoming increasingly prevalent with the widespread adoption of XR headsets like Microsoft HoloLens 2, Meta Quest 3, and Apple Vision Pro. These technologies enable users to interact with virtual elements through intuitive methods such as eye tracking, hand gestures, and voice commands, marking a significant shift towards more natural human-computer interaction.
The study classified interactions based on application scenarios, operation types, and interaction modalities. Operation types were categorized into seven distinct categories, distinguishing between active interactions (where users input information) and passive interactions (where users receive feedback). Interaction modalities were explored across nine types, ranging from unimodal interactions (such as gesture, gaze, speech, or tactile) to various multimodal combinations.
The analysis revealed several key trends. Hand gesture and eye gaze interactions, including their combined modalities, remain the most prevalent. However, there has been a notable surge in speech-related studies in 2024, likely driven by recent advancements in LLMs. In terms of operation types, pointing and selection continue to be the most focused area, although the number of studies has been decreasing annually, possibly due to the maturity of this research area. Conversely, research on locomotion, viewport control, typing, and querying has increased, reflecting a growing emphasis on users' subjective experiences and the integration of LLMs.
The researchers also identified several challenges in current natural interaction techniques. For example, gesture-only interactions often require users to adapt to complex paradigms, increasing cognitive load. Eye gaze interactions face the 'Midas touch' problem, where users unintentionally select items they are merely looking at. Speech-based interactions struggle with latency and recognition accuracy.
Based on these findings, the research team proposed several potential directions for future research. They suggested developing more accurate and reliable natural interactions through multimodal integration and error recovery mechanisms. They also emphasized the need to enhance the naturalness, comfort, and immersion of XR interactions by reducing physical and cognitive load. Leveraging AI and LLMs to enable more sophisticated, context-aware interactions was another key recommendation. Finally, they highlighted the importance of bridging interaction design and practical XR applications to encourage wider adoption.
The paper included detailed illustrations of various interaction techniques, such as gesture-based drawing, gaze vergence control, and LLM-based speech interactions, providing a valuable reference for researchers and practitioners in the field. This review offers crucial insights for researchers designing natural and efficient interaction systems for XR, ultimately contributing to the advancement of spatial computing technologies that could transform how we interact with digital information in our daily lives.
