Rule-base formulation for clips-based work ergonomic assessment

Modern societies are dominated by computer-based work. As a result, people tend to be seated for most of their working life. Prolonged sedentariness is known to significantly increase the risk of developing unwanted conditions. This paper presents the development of a rule-based expert system module using CLIPS that provides ergonomic assessment. The system was validated by evaluating pre-recorded user logs from real-life office environments. The tests showed that the system is able to perform the required basic assessment functionality, thus, the implementation of more complex features to advance its development is viable.
