E-Tech Talks (3): Look Different

Edible Projection Mapping

Emerging Technologies Talk: A new projection mapping technology for foods is demonstrated. The technology is based on edible retroreflectors that are optical devices made from edible foodstuff. Since visual recognition of the retroreflectors is simple and stable, projection mapping on foods can be installed easily and effectively.

Speaker(s): Hiromasa Oku, Gunma University, Japan

Hiromasa Oku received the B.S. in Physics, 1998, and the M.Eng. and Dr.Eng. degrees in Mathematical Engineering and Information Physics, in 2000, and 2003, respectively, from the University of Tokyo, Japan. He had been a Research Associate, Assistant Professor and a Lecturer at the University of Tokyo. Since 2014, he has been an Associate Professor at the Gunma University, Gunma, Japan. His current research interests include dynamic image control that is to provide adequate visual information to a human in a comprehensible and intelligible way by the control of optics, illuminations, and image processing.

Spatially augmented depth and transparency in paper materials

Emerging Technologies Talk: The purpose of this installation is to demonstrate novel perceptual effects in which the compelling illusion of depth and transparency for paper materials is induced by the conventional light projection of cast shadow patterns. The audience can interactively enjoy experiences wherein objects and letters on a paper perceptually float up.

Speaker(s): Takahiro Kawabe, NTT Communication Science Laboratories, Japan

Takahiro Kawabe is a senior research scientist, Sensory Representation Group, Human Information Science Laboratories, NTT Communication Science Laboratories. He received a Doctor of Psychology from Kyushu University, Fukuoka, in 2005. In 2011, he joined NTT Communication Science Laboratories, where he studies applied aspects of human perception. He received the 2013 JPA Award for International Contributions to Psychology: Award for Distinguished Early and Middle Career Contributions from the Japanese Psychological Association. In 2018, he was also awarded The Young Scientists’ Prize of The Commendation for Science and Technology by the Minister of Education, Culture, Sports, Science and Technology.

VarioLight: Hybrid Dynamic Projection Mapping Using High-speed Projector and Optical Axis Controller

Emerging Technologies Talk: This paper proposes VarioLight: a method for realizing dynamic projection mapping (DPM) onto a widely moving and finely deforming/rotating object, by combining a high-speed/low-latency projector and a mirror-based high-speed optical axis controller. It realized DPM applications such as projection sticking even to highly dynamic object and visualization of its dynamics.

Speaker(s): Yuri Mikawa, The University of Tokyo, Japan

Graduated from Department of Information Physics, Faculty of Engineering, University of Tokyo in 2018. Member of The Virtual Reality Society of Japan. My research is about Dynamic Projection Mapping and Dynamic Fabrication. Interested in Mixed Reality, Augmented Reality, Image Processing and Recognition, High-Speed Optical Axis Control.

Tangible Projection Mapping: Dynamic Appearance Augmenting of Objects in Hands

Emerging Technologies Talk: “Tangible Projection Mapping” is dynamic appearance augmentation to object in user’s hands. This technique allows users to hold a target object freely and augments appearance of that in various postures by user’s manipulation. It can provide a deep sense of unity with the attractively enhanced object in hands.
