Mobile Computing Lab.

About Us

At the Mobile Computing Lab. (Yamaguchi Lab.) of the Graduate School of Information Science and Technology, Osaka University, JAPN, we explore technologies that contribute to the development of cities, people, and communities, with Cyber-Physical Systems (CPS) as our core. Our research activities focus on application domains such as smart cities, advanced transportation systems, disaster prevention and risk management, space and satellite technologies, and intelligent environment realization, as well as their foundation layer technologies (system infrastructure, communication and computing infrastructure, and data processing and analysis technologies).

Research ― Digital Twin & CPS ―

With Cyber-Physical Systems (CPS) as our core, we explore technologies that contribute to the development of cities, people, and communities. Our research activities focus on five application domains (Smart Cities & Buildings, Smart Mobility & Transportation, Disaster Prevention & Risk Management, Space & Satellite Technologies, and Intelligent Environment & Human Behavior Sensing) and three foundation technology layers (System Infrastructure, Communication & Computing Infrastructure, and Data Processing & Analysis Technologies).
