The International Symposium on Community-centric Systems (CcS 2020) is organized by the Research Center for Community-centric Systems, Tokyo Metropolitan University. The conference will be held in Tokyo, Japan, from September 23rd to 26th, 2020. The conference offers a unique and interesting platform for scientists, engineers and practitioners throughout the world to present and share their recent research and innovative ideas on community-centric systems (CcS) that can improve quality of life (QOL) and quality of community (QOC).

Recently, the Brain-Computer Interface (BCI) system could support various aspects of everyday life of elderly and disabled people. In this research, we developed a noninvasive BCI system that controls the robot hand using induced brain waves Steady-State Visual Evoked Potential (SSVEP) in order to improve the quality of life of patients with hands or arms deficient or impaired. This BCI system consists of visual stimulator, 6 degree of freedom (DOF) robot hand, an EEG recorder and a laptop for processing data. The subject induces the corresponding SSVEP signal by seeing one target in the three visual stimuli (5Hz, 6Hz, 7Hz) representing the motion: grip, pinch and arm rotation of the robot hand. The detected SSVEP signal is classified by canonical correlation analysis (CCA). The robot hand is operated by converting the SSVEP into the control signal according to the classification result. The results show that the proposed BCI system has a high performance, achieving the average accuracy of 97% in a time window length of 4 s and the use of three harmonics.
