Research

At SiR@HKU, we envision a future where technology is no longer a separate entity, but a seamless, symbiotic extension of human capability and environmental intelligence. Our research is anchored in a long-term commitment to this visionary framework: building an integrated, enduring ecosystem that harmonizes human potential with intelligent spaces. By engineering robust, real-world systems, we are not just prototyping for today, but laying the foundation for the next generation of situated, human-centric computing.

Human Augmentation: Empowering Human Capabilities

We redefine the boundaries of human performance by weaving intelligence directly into the human experience. Our mission is to move beyond external tools toward a future of Human-Computer/AI Integration, where technology functions as a seamless, symbiotic extension of the self.

Embodied AI & Agency: We develop intelligent agents that inhabit and learn through physical or virtual bodies, fostering a deep co-evolution between human intent and machine execution in complex environments.
Telexistence: We project human agency and perception across vast distances, utilizing high-fidelity multisensory feedback to enable immersive interactions that transcend physical presence.
Cybernetic Avatars: We create digital and robotic counterparts that extend the human self. These avatars serve as intuitive interfaces for remote collaboration, social interaction, and physical task execution.
SportsHCI & Skill Acquisition: By leveraging situated feedback and interactive systems, we explore the future of athletic performance—accelerating skill mastery and redefining how humans engage in competitive and recreational physical activities.
Superhuman Interaction: We push human abilities beyond biological constraints. Through advanced sensory extension and cognitive boosting, we empower individuals to perceive and interact with the world in ways previously impossible.

Situational Spatial Intelligence: Understanding Context

Intelligence must be "situated" to be meaningful. We develop systems that go beyond raw data to perceive, reason, and act within the nuances of physical spaces and human intent in real-time. We transform static environments into dynamic, intelligent mediums.

Context-Aware Proactive AI: We move beyond reactive commands toward anticipatory embodiment. By fusing multimodal environmental cues, our AI agents predict user needs and provide just-in-time support before a conscious request is even made.
Intelligent & Adaptive Spatial UI: We design interfaces that perform spatial negotiation with their surroundings. These UIs sense physical geometry and cognitive load in real-time, automatically evolving their form, placement, and visibility to harmonize with the user's environment.
Deep Semantic Understanding: We decode the functional "logic" of a space. By recognizing object affordances and human activity patterns, we ensure that digital overlays respect the semantic and physical reality of the world, rather than just floating in space.
Diminished Reality: We empower users through perceptual reconfiguration. By digitally "cleaning" or removing physical clutter and distractions, our systems allow users to focus on mission-critical information within complex, high-stakes task environments.
Collaborative Situated Agency: We orchestrate shared mental models across distributed users and autonomous agents. By synchronizing spatial intelligence, we enable seamless collective action and co-presence in XR, regardless of physical distance.

Robust & Deployable XR Systems: Bridge to Reality

We engineer high-performance, resilient XR infrastructures designed to function flawlessly in uncontrolled, everyday environments. We bridge the gap between experimental prototypes and mission-critical applications.

Next-Generation XR Infrastructure: We optimize the underlying "hard" technology, from ultra-low latency networking to edge computing, ensuring that high-fidelity situated reality remains seamless and responsive even in demanding scenarios.
Scalable & Resilient Architecture: Our systems are built for stability across diverse hardware ecosystems and environmental conditions, ensuring that augmented experiences are consistent, persistent, and universally accessible.
Human-Centric Engineering: We focus on the usability and reliability of deployment, making complex XR systems "invisible" and intuitive for professional and casual users alike.
