Q&A for Realistic Volumetric 3D Display Using Physical Materials

Abstract: In this study, a new swept volumetric 3D display is designed using physical materials as screens. We demonstrate that a realistic 3D object, such as a knitted wool or felt doll, can be perceived using a glasses-free solution in a wide-angle view with hidden-surface removal based on real-time viewpoint tracking.

Q&A for Dynamic Projection Mapping with Networked Multi-projectors Based on Pixel-parallel Intensity Control

Abstract: We present a new dynamic projection mapping method based on pixel-parallel intensity control with multiple networked projectors. This method can solve the occlusion problem between objects well and seamlessly merge into augmented surfaces at high speed. The throughput of our system was 360 fps, which can hardly be noticeable visually.

Q&A for MaskBot: Real-time Robotic Projection Mapping with Head Motion Tracking

Abstract: We are introducing MaskBot, a real-time projection mapping system operated by a 6DoF collaborative robot. The collaborative robot locates the projector and camera in normal position to the face of the user, a webcam is used to detect the face. MaskBot projects different images on the face of the user.

Q&A for High-Speed Human Arm Projection Mapping with Skin Deformation

Abstract: This paper proposes a high-speed human arm projection mapping system with accurate skin deformation. The latency of the developed system was 10 ms, which can hardly be noticeable visually. Compared to the conventional methods, this system provides more realistic experiences that enable digitally applied tattoos and special effects makeup.

Q&A for CoVR: Co-located Virtual Reality Experience Sharing for Facilitating Joint Attention via Projected View of HMD Users

Abstract: We propose "CoVR," a co-located VR sharing system for HMD and non-HMD users by projecting the view of HMD user with a projector mounted on an HMD. Not only is this system quite easy to install but triggers joint attention and facilitates interactions by presenting different information for both users.
