  The novel concept of a Cyber-Human Social System (CHSS) and a diverse and
pluralistic 'mixed-life society' is proposed, wherein cyber and human societies
commit to each other. This concept enhances the Cyber-Physical System (CPS),
which is associated with the current Society 5.0, a social vision realised
through the fusion of cyber (virtual) and physical (real) spaces following
information society (Society 4.0 and Industry 4.0). Moreover, the CHSS enhances
the Human-CPS, the Human-in-the-Loop CPS (HiLCPS), and the Cyber-Human System
by intervening in individual behaviour pro-socially and supporting consensus
building. As a form of architecture that embodies the CHSS concept, the
Cyber-Human Social Co-Operating System (Social Co-OS) that combines cyber and
human societies is shown. In this architecture, the cyber and human systems
cooperate through the fast loop (operation and administration) and slow loop
(consensus and politics). Furthermore, the technical content and current
implementation of the basic functions of the Social Co-OS are described. These
functions consist of individual behavioural diagnostics, interventions in the
fast loop, group decision diagnostics and consensus building in the slow loop.
Subsequently, this system will contribute to mutual aid communities and
platform cooperatives.
