Center Overview
At this research center, researchers from various fields collaborate on research toward the realization of a user-friendly ambient intelligence that complements and enhances human activities. Based on this ambient intelligence, we aim to realize a diverse society where a wide variety of people can thrive, regardless of gender, nationality, or age.
Keywords and Main Research Themes
Ambient intelligence, sensing, mining, networking, actuation, diverse society
Fiscal Year 2020 Business Plan
■Background, Rationale, and Goals for Continuing Activities from Fiscal Year 2019
To date, we have engaged in numerous collaborations with universities, industries, and local governments both in Japan and abroad, and have already achieved many results. We have also been disseminating many of our achievements, including through international collaborations such as holding workshops overseas. For example, in terms of collaboration with local governments, we have established a joint research system with Fujisawa City, based on which we are advancing many demonstration experiments. As for international joint research, many members, starting with the center's director, Professor Ohtsuki, are already conducting international joint research and achieving results. Furthermore, as mentioned above, our application with Professor Ryu of Korea for the JSPS Bilateral Joint Research Projects/Seminars was accepted, and preparations for future international exchange development are in place. In addition, we have applied for the JST's international collaboration program on IoT, a trilateral collaboration between Japan, China, and Korea. To further advance our research, produce results, and disseminate information, it is desirable to continue the joint research at this center.
■Goals and Content of New Activities for Fiscal Year 2020 and Background for Implementation
Building on the collaborations with local governments and domestic and international partners that have already begun, we are planning the following activities.
First half of FY2020: Hold multiple special lectures on ambient intelligence
First half of FY2020: Give special lectures at overseas universities
First half of FY2020: Hold a center-sponsored workshop on ambient intelligence
Second half of FY2020: Hold multiple special lectures on ambient intelligence
Second half of FY2020: Give special lectures at overseas universities
Second half of FY2020: Hold a center-sponsored workshop on ambient intelligence
In addition, to strengthen our activities, we plan to jointly apply for numerous research grants, such as Grants-in-Aid for Scientific Research (Kakenhi) and those offered by NICT-NSF.
Fiscal Year 2019 Business Report
■Implementation Details, Research Results, and Degree of Achievement Relative to the Business Plan for the Fiscal Year
This research center was launched in the second half of fiscal year 2017, and this fiscal year we also carried out several projects as shown below. We also jointly applied for several research funds for the next fiscal year and beyond. Thus, progress is being made smoothly and according to plan.
The implemented projects are shown below.
September 2019: The center's director, Professor Ohtsuki, conducted a special seminar at Nanjing University of Posts and Telecommunications.
October 2019: Co-hosted the 25th Keio Leading-edge Laboratory of Science and Technology (KLL) Industry-Academia Collaboration Seminar, where the center's director, Professor Ohtsuki, and member Lecturer Kishimoto gave presentations.
October 2019: Held a special lecture (Guest Professor (Global) Prof. P. Gan Gui, Nanjing University of Posts and Telecommunications).
In preparation for the next fiscal year's activities, we jointly applied for multiple research grants, including Grants-in-Aid for Scientific Research (Kakenhi) and those offered by foundations. Among these, our application with Professor Ryu of Korea for the JSPS Bilateral Joint Research Projects/Seminars was accepted.
