Realtime physiological condition and location monitoring of street orienteering participants

To make street orienteering sports attractive and interesting to global online viewers it is important to build a system that is capable of tracking mobile competitor positions in real-time using global positioning systems (GPS) and wireless networking to collect information at a central server to be displayed to the viewers. Another important aspect of such a real-time system is the ability to monitor physiological condition of the participants. Existing systems used in orienteering sports events are unable to facilitate these features. They mostly perform offline analysis of navigation mistakes, race planning decisions and tactics only after the course is finished and digital contents of the RFID device are loaded into a PC. Therefore, in this paper, we describe the architecture and implementation of a real-time physiological condition and location monitoring system for street orienteering participants. This will allow spectators to view progress of participants and monitor changes in physiological conditions such as heart rates, blood oxygen level etc. from publicly viewable web.
