Maritime usability study by analysing Eye Tracking data

Abstract

The aim of the Integrated Navigation System (INS) on a ship bridge should be to provide the navigator with added value and aid in the complex task of conducting a safe and efficient passage in high speeds in demanding waters. This article presents a method for analysing eye tracking data to reveal sub-optimal design in the bridge layout and in the software graphical user interface on a maritime navigation display. The analysis of eye tracking data with focus on scan path events indicates sub-optimal design, and the paper provides suggestions for improvement in design and interface. Pros and cons of using Eye Tracking Glasses in a maritime environment is presented. The importance of not affecting the normal behaviour of the navigator by collecting data is stressed, and also how the software should provide good visualisation and interpretation of the eye tracking data.
