Cyber–Human Social Co‐Operating System: Application Design and Implementation

ABSTRACT Cyber‐physical systems have been proposed for Industry 5.0 and Society 5.0. One such CPS is the Social Co‐OS (cyber–human social co‐operating system). Social Co‐OS is a co‐operating system between cyber and human societies that views the social system as a dynamic circular structure composed of three layers: individual behaviour, interindividual interaction and institutional formation. Within this framework, the cyber system supports collective decision‐making and individual cooperative behaviour across these layers. The objective of this study is to define a novel application architecture based on the Social Co‐OS concept, design a user interface flow and implement it in practice. Specifically, we develop a social impact evaluator, a pluralistic policy simulator and a consensus‐building facilitator, which constitute the deliberative and political loop of Social Co‐OS. Additionally, we implement a personality estimator and a behaviour change promoter, which constitute the operational and administrative loop, along with a common mediator that serves as the cyber–human interface. Through these implementations, we demonstrate that Social Co‐OS applications can effectively support human social systems and offer practical utility for policy co‐making and cooperation as evidenced by examples grounded in real‐world challenges. In the future, we aim to promote the wider adoption of digital democracy and cooperative platforms.
