Abstract: | In urban rail trains, traditional printed guide information interfaces are being replaced by digital interfaces. An electronic guide screen is an important device for passengers to obtain information about the ride because the train is running underground. In particular, when the train is crowded, passengers must obtain information in advance and make appropriate decisions. Therefore, it is important to efficiently search for guidance interfaces. In this study, use scenarios of the guidance interface were simulated. The typical information layout and display mode in the current electronic guidance interface were the experimental variables. Through eye tracking and subjective evaluation, the effects of design features on user search performance, visual behavior, and usability satisfaction were discussed. The experimental results showed that the information layout and display mode of the guidance interface had an interactive effect on the task completion time, fixation counts, and usability score; they also had a significant effect on the recall accuracy and saccade ratio. Task completion time had a strong positive correlation with usability satisfaction and was correlated with visual behavior. The study confirmed that the split-screen display mode combined with interlaced layout could improve search performance and subjective satisfaction.Relevance to industryPrinted guide signs in subway cars are being replaced by electronic guide screens of different styles. Passengers must search for the required information within a limited period. In this study, the effects of different interface layouts and display modes on search performance, visual behavior, and usability were studied. This had a positive significance in improving user experience. |
