The effect of a superimposed display on navigational performance
conference paper
A simulator experiment was conducted to investigate the potential benefits of a maritime Superimposed Information Display (SID). Participants were requested to cross a traffic separation scheme with a high-speed vessel. Two display types were used: (i) standard Automatic Radar Plotting Aid (ARPA) navigation display information with advanced collision-avoidance facilities; (ii) ARPA display information supplemented with a SID, presenting information projected over the outside world scene with a horizontal viewing angle of 100°. In the SID, a cursor was available to select possible (unidentified) objects in the out-of-the-window scene; the selected object's position was then calculated and included in the ARPA collision avoidance calculations. The participants were instructed to keep all traffic vessels as well as unidentified objects at a minimum safety distance of 1.0 nm. Task difficulty varied with the number of vessels in the traffic situation. Performance was assessed in terms of time to detect the unidentified object and in terms of violation of the minimum safety distance to any floating object. Results of the experiment indicate that there was a significant improvement in detection speed of unidentified objects when a SID was used. Further, it was found that unidentified objects were avoided more safely with a SID. Although the experimental results seem promising, many technical problems must be solved before SIDs may be successfully used in maritime applications.
Uit een simulator experiment blijkt dat een navigator in druk vaarwater niet-geidentificeerde drijvende objecten gemiddeld een factor vijf sneller opmerkt wanneer wordt gevaren met een head-up display. Tevens blijkt dat bij deze objecten de opgelegde veiligheidsafstand significant beter wordt gehandhaafd.
