Abstract:

This study focuses on drivers’ allocation of visual attention while interacting with a visual-manual in-vehicle Human-Machine Interface (HMI) to understand how drivers manage their attention. Drivers’ glance behaviors while completing radio-tuning tasks were manually coded and analyzed. The relationship between the duration of glances to the radio and the frequency of glances was tested and compared across younger (20-29) and older (60-69) drivers. Results showed that older drivers engaged in more glances, longer single glances, and have longer total glance times. Older drivers also showed higher variability in glance durations than younger drivers. Significant negative correlations between glance duration and glance frequency were also observed with both older and younger drivers. This was consistent with – and supported – two types of glance strategies that were hypothesized to be used for completion of HMI tasks. Additional correlation tests revealed that self-reported frequent users of in-vehicle systems completed the HMI tasks with shorter and fewer glances. These results indicate that there are distinct glance strategies employed in the completion of visual-manual HMI tasks – by younger and older drivers. Further, older drivers required more time to visually extract information in order to complete tasks regardless of the strategy used. Finally, a discussion of how different glance strategies may affect safety and risk – a topic that can be explored in future research – is provided.
