MRsionCase: A Glasses-free Mixed Reality Showcase for Surrounding Multiple Viewers

MRsionCase provides users visual information through multi-layered floating images along with the real objects inside the showcase. Since the mid-air images are formed from optical devices, users can see them without additional device. In addition to the visual information, localized auditory information is realized by hyper directional loudspeakers.

Robust 2D-3D Matching for 3D Object Pose Detection - Picture

Robust 2D-3D Matching for 3D Object Pose Detection

We present a novel 2D-3D matching method, which is applicable to pose detection of the target 3D object. It can robustly match points regardless of the object pose and improves the matching performance of the conventional keyframe-based method.

Efficient Rasterization for Edge-Based 3D Object Tracking on Mobile Devices - Picture

Efficient Rasterization for Edge-Based 3D Object Tracking on Mobile Devices

Augmented reality applications on consumer-grade hand-held devices suffer from the limited available processing power. By focusing on key behaviors of edge-based models, we present a sparse depth buffer structure to provide an efficient CPU-based rasterization method.

Haptic Editor: Creation and Editing System for Touchable 3D Content  - Picture

Haptic Editor: Creation and Editing System for Touchable 3D Content

Haptic Editor is an interactive content creation system for haptic-enabled 3D content. The user creates haptic 3D models by drawing geometries through aerial sketching; painting compliance and friction values on the layers; and copying and pasting the vibrotactile surface textures of real objects onto the virtual model.
