摘要: This study investigated how workload and performance in high-speed ship navigation was affected by sleep deprivation using methods based on either paper charts or electronic chart display information systems (ECDIS). In two separate weeks, five navigators sailed 10 routes high-fidelity simulators while undergoing progressive for up to 60 h. Results showed that better ECDIS, but largely unaffected both. There significant interaction between speed, method, indicating ECDIS reduced their speed more sleepy. Secondary task deprivation, equally both conditions. Workload higher the condition, as indicated subjective ratings heart rate variability. No differences sleepiness were found, electroencephalographic recordings frequent microsleep episodes condition. may be influenced lower overall arousal navigating with ECDIS.
