Mental workload assessment using eye-tracking glasses in a simulated maritime scenario

In occasione del meeting annuale della Human Factors and Ergonomic Society - Europe Chapter del 2015, abbiamo presentato il paper “Mental workload assessment using eye-tracking glasses in a simulated maritime scenario” che presenta parte delle attività che abbiamo svolto all’interno del progetto di ricerca europeo “CyClaDeS - Crew-centered Design and Operations of Ships and Ship Systems”.

Abstract:
The primary goal of this study was the assessment of maritime operators’ mental workload in simulation scenarios designed for containing typical traffic situations to be handled by officers during usual routine ship navigation. Taskload was manipulated throughout the sessions to analyse changes in ocular activity during complexity peaks. Specifically, it was tested the viability of implementing a dynamic analysis of eye movements collected through eye tracking glasses (while the operator was freely moving on the bridge) and using the distribution of eye fixations as an indicator of mental workload. Another objective of the present study was to assess the relation between attentional control and the mental workload as perceived by the operators. Results showed that the distribution of eye fixations changed with taskload and that individuals showing high attentional control reported low workload. Furthermore, frequent eye movement transitions have been found between the instruments monitored, suggesting that the information they provide could most usefully be integrated for improving the operators’ performance.

Keep calm and don’t move a muscle: Motor restlessness as an indicator of mental workload

In occasione del meeting annuale della Human Factors and Ergonomic Society - Europe Chapter del 2013, abbiamo presentato il paper “Keep calm and don’t move a muscle: Motor restlessness as an indicator of mental workload” che presenta parte delle attività che abbiamo svolto all’interno del progetto di ricerca europeo “CyClaDeS - Crew-centered Design and Operations of Ships and Ship Systems”.

Abstract:
Subtle motor activity of the gluteal muscles and legs of the operator sitting in a chair can be obtained by using capacity sensors applied to the seat itself, thus making viable to easily record variations in motor restlessness during the execution of a task. The present study was aimed at studying the relation between variations in mental workload and variations in motor activity that are unrelated to the task to perform. Preliminary results from a laboratory study employing behavioural, ocular, subjective and motor measures show that motor restlessness can be considered as a promising indicator that can be usefully integrated in any data collection procedure for assessing the operator functional state.

INTRAC: a research project on the integration of safety elements with ergonomics in the design of agricultural machinery

Abbiamo partecipato, insieme al CRA-ING, ErgoCert e PAN-PAN Edizioni, alla stesura del Paper "INTRAC: a research project on the integration of safety elements with ergonomics in the design of agricultural machinery” che è stato inserito negli Atti di RAGUSA SHWA 2012 “Safety Health and Welfare in Agro-food Agricultural and Forest Systems”.

Abstract

Designing agricultural machinery firstly takes into account the specific technical aims the machine has to reach. Only then, if a compulsory standard exists, the safety aspects related to the operator, the environment and the road circulation are carefully introduced in the design in order to not penalize the main performance. Generally, the most evident and frequent risks are considered, and rarely the possible causes of occupational diseases - that are more subtle to detect, but unfortunately, irreversible – are considered.

The present research project aims to analyze and to propose methods and models to assess the level of integration of technical and safety aspects in the designs of different working place of agricultural machineries. Vibration, noise, microclimate conditions and ergonomics will be taken into account and innovative assessment methods, for the agricultural sector, will be introduced.
