Katashi Nagao received his B.E., M.E., and Ph.D. in Computer Science from Tokyo Institute of Technology in 1985, 1987 and 1994, respectively. Since 1987, he has been researching natural language processing and machine translation systems at IBM Research, Tokyo Research Laboratory. In 1991, he began conducting research projects on natural language dialogue, multiagent systems, and human-computer interaction at Sony Computer Science Laboratories, Inc. From 1996 to 1997, he was a visiting scientist at the Beckman Institute for Advanced Science and Technology, University of Illinois at Urbana-Champaign. He rejoined IBM’s Tokyo Research Laboratory and launched the Semantic Transcoding Project in 1999. He joined Nagoya University as an associate professor at the Graduate School of Engineering in 2001. Since 2002, he has been researching artificial intelligence and computer-assisted education as a professor at the Graduate School of Information Science, Nagoya University. Currently, he is conducting research on building-scale VR that extends the daily living space by incorporating the real-world environment entirely into the virtual world, as well as research on smart personal vehicles for the elderly.

Building-Scale Virtual Reality: Another Way to Extend Real World
Katashi Nagao, Menglong Yang, Xu Cao, Yusuke Miyakawa
IEEE 2nd International Conference on Multimedia Information Processing and Retrieval   28 Mar 2019   IEEE
We propose building-scale virtual reality (VR), a real-world extension method different from augmented reality (AR), that uses automatically generated indoor 3D point cloud maps. To make the entire indoor area a pose tracking area, we attach an RG...
