As in-vehicle technologies (IVTs) grow in both popularity and complexity, the question of whether these IVTs improve, or hinder, driver performance has gained more attention. The ability to predict when a driver will be looking at the road or a display on the car’s dashboard or center console is crucial to understanding the impact of the recent tech-heavy trend in car designs on safety and the extent to which IVTs compete with the primary driving task for visual resources. The SEEV model of visual attention has been shown to be able to predict the probability of attending an area if interest (AOI) while driving based on the salience (SEEV-S) of visual stimuli, the effort (SEEV-Ef) required to shift attention between locations, the expectancy (SEEV-Ex) that information will be found at a specific location within the visual field, and the value (SEEV-V) of the information found at that location relative to the task(s) being performed. This study compared older and younger adult SEEV models calculated using eye tracking during a series of simulated driving scenarios with differing levels of effort, expectancy, and value placed on the primary driving task and a secondary in-vehicle task (IVT) to be done on the center console while maintaining lane position and speed. No significant effect of the effort variable was found, likely due to the cues used in our experiment not requiring head or torso rotation to access. Good model fits for both older and younger adults were found, with younger adults having greater weight on the dashboard AOI than older adults when the driving task was prioritized.
