How does short training on the use of in-car touchscreen influence driving performance? insights from a driving simulator study

• Driving experience is evolving with the introduction of advanced infotainment systems in vehicles. • The impact of pre-drive short training on the use of in-car touchscreens and its effect on driving performance was assessed. • Longitudinal and lateral driving performance was measured in a simulated environment. • Higher secondary task completion rates do not necessarily mean better overall driving performance. • Training programs need to be properly designed and tested to positively influence driver behaviours and performance. The automotive industry has significantly evolved with the integration of advanced technologies in car infotainment systems, leading to more interactive driving experiences. However, the usage of in-car touchscreen (ICT) interfaces poses challenges such as increased driver distraction. This study investigates the impact of instructor-led pre-drive short (PDS) training on the usage of ICT. The drivers’ performance and behaviour were assessed when using unfamiliar ICT interfaces in a driving simulation. Sixty participants divided into two groups (i.e., trained and untrained) were included and asked to perform multiple secondary tasks on the ICT while driving along a motorway section. We also measured drivers’ longitudinal and lateral behaviour in distracted and undistracted conditions. Contrary to the hypothesis that PDS training sessions would enhance driving performance through improved ICT interface proficiency, the study results show that while such training did increase task completion rates, it was not sufficient to improve overall driving performance. No statistically significant improvements were observed in longitudinal or lateral driving performance compared to untrained drivers. Nevertheless, the study found that driver performance, particularly in lateral vehicle control, improved with increased familiarity and experience. These results suggest that more extensive or alternative training methods may be necessary to address the complexities of ICT interfaces in vehicles. Future research should focus on exploring diverse training approaches and their long-term effects across different in-vehicle infotainment systems.
