Abstract
Postural stability modelling and analysis that attempts to quantify the effect of high-severity ocean environments on human performance offers the potential for providing practical insight into activities ranging from operational planning through ship design. Due to the magnitude and range of motions experienced, it is difficult to validate these models without actual rough weather sea trial data. This paper summarizes the procedures and results of postural stability and human factors research which took place on the Q-348 Quest sea trial over the course of eight days in November 2012. Thirteen participants took part in an experiment carried out by Carleton University and DRDC Atlantic researchers. Measurements were made using two full-body motion capture systems, foot pressure insoles, a six-axis load cell, and a head-mounted vision/inertial measurement system. Participants were also provided with a cognitive task to complete while maintaining balance. These tools provided quantitative measurements for the inputs and outputs of the human postural control system as it maintained balance in a typical ocean environment.
