GAZEleak: Passcode Inference Against Eye-tracking XR Devices Through External Observation
Hwanjo Heo, Junhee Lee, Jinwoo Kim
Mixed-reality headsets such as Apple Vision Pro replace the touch screen with gaze-as-pointer interaction: the wearer looks at a target and confirms with an air pinch. Because the…
UniSim-SLAM: Feed-Forward SLAM with Unified Sim(3) Optimization
Inha Lee, Dongjae Jeong, Junhee Lee +1
Recent geometric foundation models enable feed-forward inference for SLAM, but their predictions are strongly dependent on the input view set, which leads to geometric inconsistenc…
FeDepth: Federated Learning for Depth Estimation under Robot Heterogeneity
Ganghyeon Lee, Inha Lee, Junhee Lee +3
Although recent robot perception research emphasizes training on data from diverse environments to improve generalization, most existing methods still rely on centralized learning,…
HarassGuard: Detecting Harassment Behaviors in Social Virtual Reality with Vision-Language Models
Junhee Lee, Minseok Kim, Hwanjo Heo +2
Social Virtual Reality (VR) platforms provide immersive social experiences but also expose users to serious risks of online harassment. Existing safety measures are largely reactiv…
RefineVAD: Semantic-Guided Feature Recalibration for Weakly Supervised Video Anomaly Detection
Junhee Lee, ChaeBeen Bang, MyoungChul Kim +1
Weakly-Supervised Video Anomaly Detection aims to identify anomalous events using only video-level labels, balancing annotation efficiency with practical applicability. However, ex…
Illusion Worlds: Deceptive UI Attacks in Social VR
Junhee Lee, Hwanjo Heo, Seungwon Woo +3
Social Virtual Reality (VR) platforms have surged in popularity, yet their security risks remain underexplored. This paper presents four novel UI attacks that covertly manipulate u…
EO-VLM: VLM-Guided Energy Overload Attacks on Vision Models
Minjae Seo, Myoungsung You, Junhee Lee +4
Vision models are increasingly deployed in critical applications such as autonomous driving and CCTV monitoring, yet they remain susceptible to resource-consuming attacks. In this…
VPOcc: Exploiting Vanishing Point for 3D Semantic Occupancy Prediction
Junsu Kim, Junhee Lee, Ukcheol Shin +2
Understanding 3D scenes semantically and spatially is crucial for the safe navigation of robots and autonomous vehicles, aiding obstacle avoidance and accurate trajectory planning.…
