Narrative-Driven Immersive GNN Explainability
Develops a Neuro-Symbolic Immersive Interface integrating LLM-generated narratives into a real-time VR analytics loop to make Graph Neural Network (GNN) decisions interpretable for domain experts. Translates GNN latent representations into natural-language explanations rendered alongside structural graph visualizations. Controlled user studies examine how this multimodal approach affects belief formation, trust calibration, and cognitive load vs. visual-only explanations.
PORE-XR: Porous Objects Research & Exploration in XR
An immersive XR visualization platform for large-scale X-ray Computed Tomography (XCT) data supporting non-destructive evaluation of internal material structures (porosity, cracks, defects). Transforms volumetric scans into a walk-around immersive workspace with natural two-handed gesture manipulation and real-time feature isolation. Built in Unity for cross-platform deployment; demonstrated on Meta Quest, Varjo XR-3, and Apple Vision Pro. Open-source, with dynamic cutting planes, region-of-interest cutouts, annotation, and 3D measurement overlays.
XR VIEU: eXtended Reality for Visual Impairment Exploration and Understanding
A modular, real-time, gaze-contingent XR framework simulating central vision loss on the Varjo XR-4. Models seven distinct visual phenomena (e.g. spatial distortion, perceptual fill-in) associated with conditions like AMD. Each module is independently configurable per eye. Used for empathy training, inclusive design, and rehabilitation research. Collaboration with Emory University and CVI Atlanta.
