Natural Interaction: 3D Modeling in Wearable VR Using a Gesture and Speech Interface
Designers often rely on keyboard and mouse for 3D modeling, a method that can feel unintuitive or restrictive—especially in collaborative or spatially immersive settings. This thesis explores how multimodal interaction, specifically the combination of hand gestures and voice commands, can support …

A new technique for 3D modeling of water surfaces using a Geiger mode receiver
… with water turbidity. Accurate and consistent modeling of the water surface is required in order to correct for the surface’s volatility when imaging the sea floor. However, this becomes exceedingly difficult due to the limited data return from water, the uneven surface, and noise. For this …
