Abstract

This paper presents a new analysis approach for evaluating situation awareness in marine operation training. Taking advantage of eye tracking technology, the situation awareness reflected by visual attention can be visualized and analyzed. A scanpath similarity comparison method that allows group-wise comparisons is proposed. The term ‘Expert zone’ is introduced to evaluate the performance of novice operator based on expert operators’ eye movement. It is used to evaluate performance of novice operators in groups in certain segment of marine operation. A pilot study of crane lifting experiment was carried out. Two target stages of operation for the load descending until total immersion to the seabed were selected and analyzed for both novice and expert operators. The group-wise evaluation method is proven to be able to access the performance of the operator. Besides that, from data analysis of fixation-related source and scanpath, the similarities and dissimilarities of eye behavior between novice and expert is concluded with the scanpath mode in target segment.

Highlights

  • Marine operations have become more complex and diverse in recent years due to the development of technology in the marine industry

  • Mean fixation number is the parameter that can indicate how many fixation times one has over a defined period of time

  • The expert operators have the mean fixation number with 1.69 and 1.56 where these numbers are in the middle level among all participants

Summary

Introduction

Marine operations have become more complex and diverse in recent years due to the development of technology in the marine industry. It is reported that marine accidents such as offshore oil rig mishaps, crane mishaps and the grounding of ships, are usually followed by the development of new technologies. Human error has been established as one of the main threats to marine safety. Shore accidents are caused by human error (Luo & Shin, 2016). From safety to economy, it is important to understand what causes human error and learn from these failures. Briefing and debriefing are introduced in marine training, evaluation of situational awareness is seldom seen. It cannot clearly and effectively reflect the potential mistake during the training and would lay danger in real practice
