N2 - Autonomous vehicles offer a greater level of support than ever before. Highly autonomous vehicles enable drivers to be out of the loop during the automation period under certain conditions. As one of the advantages, drivers can engage non-driving-related tasks, but it can make them slower to get back in the loop when having to take back manual control. In this situation, the subjective evaluation of takeover experience cannot be the same to all drivers, having varied mental and physical abilities. This subjective experience needs to be paid attention to because it could lead to willingness to use the system. Therefore, this study aims to investigate subjective experience of a customisable human–machine interface (HMI) in a highly automated driving environment during takeover situation. It is postulated that drivers’ experience will be enhanced through the assistance of customised HMI given that it was tailored to better suit the drivers’ own needs and preferences. Subjective workload, usability, acceptance, and trust were employed as measures of subjective experience. Users were assessed before customisation using default settings (trial 1) and after customising the HMI (trial 2). Results demonstrated that workload decreased, while usability, acceptance, and trust increased in trial 2 in comparison to trial 1. Statistically significant differences were shown in workload, and trust between the trials. Statistical significance in the subjective experience between genders and age groups was not found. These indicate that a customisable HMI is helpful in eliciting a positive takeover experience compared to a default HMI, from drivers with varying abilities and needs. Moreover, offering the opportunity to customise the interface according to their needs within a certain range does not have detrimental effects on drivers’ experience. Customisable HMI could be considered as a method to assist drivers to create the driving environment that could help improve their user experience.
