Predictive displays to improve situation awareness
conference paper
A simulator experiment was conducted to determine the potential benefits of an integrated navigation display to improve the navigator's situation awareness. Twelve participants were required to navigate a medium size vessel across a vessel traffic separation scheme. Three integrated navigation display types were used: (i) basic Automatic Radar Plotting Aid (ARPA) radar information, this is considered a modern baseline navigation display type, (ii) basic ARPA supplemented with information indicating the predicted boundaries of operation, the so-called Predicted Capability Envelope (PCE) for constant propulsion of the navigator's vessel, advising about safest course to select, and (iii) basic ARPA with PCE for variable propulsion of the navigator's vessel, advising about safest course and speed to select. It was predicted that the display types with PCE would better support the navigator's situation awareness than the baseline ARPA display type, leading to a better navigational performance. Results of the experiment show that there was a significant improvement of navigation performance when PCE information was used; compared with the basic ARPA display type, a factor of four less violations of the minimum passing distance occurred.
Uit een simulator experiment bleek dat bij het varen met een geïntegreerd navigatie display op basis van de voorspelde manoeuvreer-marges de overschrijding van de minimum veiligheidsafstand tot andere verkeersdeelnemers met een factor vier reduceert
