Human Factors in the Naval Environment: A Review of Motion Sickness and Biodynamic Problems

Abstract : Two types of motion-induced problems affecting human performance in the naval environment are reviewed; motion sickness and biodynamic problems. Methods for predicting the incidence of motion sickness are described and evaluated, and problems associated with modeling complex motions are discussed. References for quantifying habituation are cited and methods for defining the severity of motion sickness symptoms are described. Biodynamic problems are briefly discussed, including the low-frequency, large-amplitude problems of motion-induced interruptions (MII) and fatigue; and the higher-frequency problems of manual control and vision. Methodologies and criteria for evaluating human performance within the systems approach to seakeeping assessment are discussed and topics for future work are recommended.
