Automated link analysis using radio frequency identification (RFID)

Being able to accurately record the interactions which take place within any environment is beneficial for understanding human behaviour in a wide range of industries. Link Analysis is a standard technique which is often used, but traditional pen and paper methods are cumbersome and time consuming. This paper details a way to automate recording the interactions between a human and their current environment by using radio frequency identification (RFID) tags and a subject-mounted receiver. Using the results from the system, it is possible to instantly create conventional Link Analysis diagrams and tables, reducing the time and resources required for data collection and analysis. The system has been developed in partnership with the Healthcare Ergonomics and Patient Safety Unit (HEPSU) at Loughborough University, with initial focus being on monitoring paramedics, patients and environment interactions within an ambulance; however, the technologies and the analyser system are not limited to use within this particular field.
