Towards Vehicle Content Accessibility Guideline

This study entails the current status of the accessibility in vehicle. With the movement of Software-Defined-Vehicle (SDV), automobiles transform into a digital device with larger screen and connected content service including map. However, it is questionable if the contents in vehicle is accessible to all. We often experience a feeling of "disabled" when we cannot 1) perceive the content on screen 2) operate the function with interactive components, or 3) understand the messages from the vehicle that we are driving with. How can we diagnose the current in-vehicle accessibility to find the direction to improve? The current issue on vehicle content accessibility is related to the missing of vehicle content accessibility guideline. This study reviews current guidelines and regulation in the U.S.A and introduce the draft of vehicle content accessibility guideline (VCAG) that can contribute to enhanced accessibility of in-vehicle digital content and app. Recognizing the unique challenges posed by the driving context, the research explores methods to test interface design, content presentation, and interactive features to ensure universal design and content accessibility while minimizing cognitive overload for drivers.
