Video analysis for performance modeling in real environments: Methods and lessons learnt

Widely available video recording technologies have made the use of video recording a primary choice of data gathering tools in the study of performance in complex and dynamic environments, both real and simulated. This paper describes an 8-year research program based on video recording in a medical domain. Data extraction and analysis techniques used in the program are outlined along with solutions to logistic problems, in the hope that other researchers of performance can draw lessons from our efforts
