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>

本研究旨在探究驾驶过程中车辆操控装置的使用频次，以及影响其使用的潜在因素。本研究选取30名驾驶员作为观测对象，要求其分别驾驶自有车辆与陌生车辆，沿熟悉路线完成两次行驶。本实验采用2×1被试内实验设计，主试陪同每名被试驾车行驶，并通过预先设定的检查表记录被试在驾驶过程中操作车辆特定功能的频次。本数据集包含与哈姆斯（Harms）等人发表的论文《驾驶中常用车辆操控装置：一项评估车内人机交互（Human-Machine Interface, HMI）任务频次与影响因素的真实驾驶研究》相关的内容，具体包括观测检查表（部分A）、数据与结果表格（部分B）以及知情同意书（部分C）。
