Research on the Spacing and Gaze-Trigger Duration of Eye-Controlled Interaction Controls in Ship Motion Environments

Human factors engineering is critical in offshore operations. With the development of new human-computer interaction technologies, interaction methods such as eye tracking, voice commands, and gestures are gradually being applied to ship control platforms, demonstrating advantages such as ease of use and natural interaction. However, in ship motion environments, the precision of operations like manual or head movements may decline. In contrast, eye movements are minimally affected, making eye-controlled interaction an important area of research. Based on a review of the literature, this study uses a six-degree-of-freedom motion platform to simulate various ship motion environments encountered by operators. Eye-tracking experiments are conducted to determine the optimal spacing of controls and trigger time thresholds for gaze-based interactions under motion conditions. Furthermore, the study explores the impact of different ship motion scenarios on the performance of eye-controlled interaction, aiming to enhance the safety and efficiency of offshore operations.
