Holistic HMI Design for Automated Vehicles: Bridging In-Vehicle and External Communication

TL;DR

This paper advocates a holistic HMI design framework for automated vehicles, emphasizing coherent communication across internal and external road users. It proposes a dedicated workshop at AutomotiveUI that uses participatory physicalisation to surface real-world use cases and foster cross-domain collaboration between iHMI and eHMI researchers. The format combines keynote insights with hands-on, tangible group activities to generate a shared understanding and actionable directions. The expected contributions include a summary report and an academic article that establish early consensus and guide future design and research for seamless AV integration into mixed traffic.

Abstract

As the field of automated vehicles (AVs) advances, it has become increasingly critical to develop human-machine interfaces (HMI) for both internal and external communication. Critical dialogue is emerging around the potential necessity for a holistic approach to HMI designs, which promotes the integration of both in-vehicle user and external road user perspectives. This approach aims to create a unified and coherent experience for different stakeholders interacting with AVs. This workshop seeks to bring together designers, engineers, researchers, and other stakeholders to delve into relevant use cases, exploring the potential advantages and challenges of this approach. The insights generated from this workshop aim to inform further design and research in the development of coherent HMIs for AVs, ultimately for more seamless integration of AVs into existing traffic.
