RealTwin: Concept Graph Representation and Grounding Framework for Reality-Preserving Digital Twin Reconstruction

Reconstructing realistic digital twins has become crucial as advances in mixed reality, metaverse, and robotics demand more accurate simulations for the physical world. Despite technical progress, building high-fidelity digital twins from a systematic and human-centered perspective remains underexplored. Drawing from…

InteRecon: Towards Reconstructing Interactivity of Personal Memorable Items in Mixed Reality

Digital capturing of memorable personal items is a key way to archive personal memories. Although current digitization methods (e.g., photos, videos, 3D scanning) can replicate the physical appearance of an item, they often cannot preserve its real-world interactivity. We present Interactive Digital Item (IDI), a conc…

ACKnowledge: A Computational Framework for Human Compatible Affordance-based Interaction Planning in Real-world Contexts

Intelligent agents coexisting with humans often need to interact with human-shared objects in environments. Thus, agents should plan their interactions based on objects' affordances and the current situation to achieve acceptable outcomes. How to support intelligent agents' planning of affordance-based interactions co…

Exploring the Opportunities of AR for Enriching Storytelling with Family Photos between Grandparents and Grandchildren

"Storytelling with family photos, as an important mode of reminiscence-based activities, can be instrumental in promoting intergenerational communication between grandparents and grandchildren by strengthening generation bonds and shared family values. Motivated by challenges that existing technology approaches encoun…

ShadowTouch: Enabling Free-Form Touch-Based Hand-to-Surface Interaction with Wrist-Mounted Illuminant by Shadow Projection

We present ShadowTouch, a novel sensing method to recognize the subtle hand-to-surface touch state for independent fingers based on optical auxiliary. ShadowTouch mounts a forward-facing light source on the user's wrist to construct shadows on the surface in front of the fingers when the corresponding fingers are clos…

Enabling Voice-Accompanying Hand-to-Face Gesture Recognition with Cross-Device Sensing

Gestures performed accompanying the voice are essential for voice interaction to convey complementary semantics for interaction purposes such as wake-up state and input modality. In this paper, we investigated voice-accompanying hand-to-face (VAHF) gestures for voice interaction. We targeted on hand-to-face gestures b…
