Enhancing Automotive Interface Design: Insights from Touchscreen Usability and Driver Interaction Studies

Abstract: The evolution of Human-Machine Interface (HMI) systems in the automotive sector marks a significant shift from traditional mechanical controls to sophisticated touchscreen interfaces. This transition reflects broader technological trends and user expectations, integrating large-screen interfaces that combine information, entertainment, and connectivity to enhance the driving experience. The focus on intuitive and adaptive design is critical in improving interaction quality and safety, demonstrating how modern automotive interfaces are increasingly shaped by the principles of user-centred design.Challenges such as interaction accuracy under varying road conditions and ergonomic considerations associated with increasing touchscreen sizes and placements within vehicle cabins are also examined. Studies on the effectiveness of various interaction techniques, including haptic feedback mechanisms, are evaluated for their role in mitigating distractions and enhancing user satisfaction. This paper highlights the necessity for advanced, adaptive HMI systems that can dynamically respond to environmental perturbations and user preferences to ensure safety and efficiency. Based upon the current literature, a comprehensive approach is proposed that integrates user-centred design, data mining, machine learning, and adaptive buttons close to the user to develop more intuitive and robust automotive HMIs. As vehicles advance towards greater autonomy, the continued collaboration and innovation in HMI design will be crucial in aligning with evolving user expectations and driving dynamics, ultimately contributing to safer and more efficient vehicle interfaces.
