Abstract [Objective] This paper investigates the impacts of time constraint on users’ information behaviors in pedestrian navigation and their interaction experiences. [Methods] We recruited 20 college students and randomly divided them into two groups (with and without time constraint) for the pedestrian navigation experiment. These participants completed two different types of tasks: Outdoor and Indoor Pedestrian Navigations. [Results] We found that time constraint induced some feeling of stress. However, there was no significant difference among the strength of time pressure. Once the users did not know their destination and its exact location, the time constraint posed significant impacts to task duration, time spent on text page and the number of slides on the screen. When users knew their destination but did not know its specific location, the time constraint has no significant impact on users’ information behaviors. For indoor navigation, users’ zooming and sliding activities were significantly influenced by time constraint. [Limitations] The number of participants in our experiment is small. [Conclusions] Time constraint affects the information behaviors of pedestrian navigation system users. With time constraint, they could reach the destination quickly by reducing screen operations.
