My main theme is the utilization of social media at the time of disaster. I am currently focusing on sharing disaster information using Twitter and analyzing the characteristics of tweets posted during disasters. The disaster information sharing system DITS/DIMS (Disaster Information Tweeting and Mapping System) developed by our laboratory is an application that allows users to easily post disaster information. The system is also used in disaster prevention drills and education.ResearchAreasComplex systemsKeywords■Disaster information■Social media■Twitter■Disaster prevention education■Mobile applicationRelatedresearchSDGUtilization of social media for disaster risk reductionProfessorOsamu UchidaUndergraduate School of Information Science and TechnologyDepartment of Human and Information ScienceProf. Takao has developed psychophysiological measurement technology of industrial products with Japanese manufacturers. Several years ago, he started new virtual reality (VR) technology project. He has an interest in the processes of psychophysiological adaptation to VR environments. He has already found that blink rate changes depending on subjective immersive experience and 3D-maze learning performance in huge virtual spaces that were created by computer graphics techniques. These ndings indicate that eye blink recording will be a physiological measurement suitable for usability evaluation of VR games. In addition to these experimental studies, he collaborates with medical practitioners and develops special VR games to prevent dementia and to treat apathy and depressive symptoms in elderly people.ResearchAreasComplex systemsKeywords■Virtual reality■Product usability■Video games■Psychophysiology■Visual scienceRelatedresearchSDGApplication of psychophysiological measurement technology to industrial innovationProfessorMotoharu TakaoUndergraduate School of Information Science and TechnologyDepartment of Human and Information ScienceHe is an expert on remote sensing mainly focusing on monitoring earth environment from space using earth observation satellites. His scientific interest includes but not limited to sea ice monitoring using passive microwave sensors, disaster monitoring from space, and image processing. He is conducting a project on monitoring the recovery of the disaster-aected areas using remote sensing funded by JSPS since 2012. He is also a PI of JAXA AMSR2 sea ice team. He has been the General Secretary of the Asian Association on Remote Sensing(AARS) for 10 years.ResearchAreasInformaticsKeywords■Remote sensing□Image processing　■Disaster monitoring□Earth Environmental monitoringRelatedresearchSDGRemote Sensing for monitoring the earth environmentProfessorKohei ChoUndergraduate School of Information Science and TechnologyDepartment of Human and Information Science70
