Supplementary data for the article "Frequently used vehicle controls while driving: A real-world driving study assessing internal HMI task frequencies and influencing factors"

The purpose of this study was to investigate how often vehicle controls are used while driving and which underlying factors contribute to usage. Thirty drivers were observed during driving a familiar route twice, in their own car and in an unfamiliar car. In a 2 × 1 within-subject design, the experimenter drove along with each participant and used a predefined checklist to record how often participants interacted with specific functions of their vehicle while driving. The document contains the observation checklist (part A), data and result tables (part B) and the informed consent form (part C) pertaining to the article by Harms et al. “Frequently used vehicle controls while driving: A real-world driving study assessing internal HMI task frequencies and influencing factors”.<br>
