The paper introduces the Active Badge Location System, a novel system designed to locate individuals in office environments. Staff wear active badges that transmit signals to a centralized location service via a network of sensors. The system aims to improve office efficiency by providing real-time location information, which can be used for various applications such as telephone call routing and security. The authors discuss the system's design, including the use of infrared signals for communication, and address privacy concerns. The system has been successfully implemented at Olivetti Research Ltd. (ORL) and other locations, showing benefits such as improved efficiency and convenience. However, privacy issues remain a significant concern, and the authors emphasize the need for legislation to protect individual rights. The paper concludes by outlining future directions for the system, including enhanced features and integration with other building management functions.The paper introduces the Active Badge Location System, a novel system designed to locate individuals in office environments.
