| dc.description.abstract | Reconstructing the 3D facial expressions of head-mounted display (HMD) wearers is essential for natural avatar communication in virtual reality (VR). Camera-based methods achieve high fidelity but involve heavy processing and privacy risks, whereas non-imaging sensors are lightweight and privacy-preserving but provide only sparse features. We propose a reconstruction system that learns high-dimensional 3D facial representations from camera images during training, but performs inference using only compact photo-reflective sensors embedded in the HMD. This design integrates the expressiveness of camera-based supervision with the efficiency and privacy of sensor-based operation. Experimental results show that our method accurately reconstructs 3D facial expressions from the sensor data, training with diverse wearing conditions is more effective than collecting more data under a single condition, and accuracy further improves with a dedicated mouth-shape predictor and lightweight personalization using small wearer-specific datasets. | en_US |
