Development of bio signal measurement system for vehicles

Abstract

This study intends to research and develop unrestricted measuring system and user interface in a new form to effectively collect individual bio information of car users - driver and passenger - with the systems previously researched and developed as basic platform. The whole system is designed to measure bio signals for monitoring the physiological changes in the vehicle. For system evaluation, an actual operating condition was offered by mounting and equipping the system in an actual vehicle, and then the measured information was analyzed and verified. Through these processes, the measured signals were evaluated and its availability in the vehicle was confirmed. In this study, the system to induce drivers to safe driving was developed through consecutive monitoring of fatigue and increased risk of safety accident as drivers drive for many hours. In addition, health care service system for driver and passenger was developed through the measurement of various bio signals. Besides, a case of unrestricted and unconscious bio signal measurement system was suggested with completely recognizing and understanding a special condition of driving. © 2007 IEEE.
