Literature Insights – Accessible in-vehicle UI
Current ADAS(Advanced Driver Assistance Systems) and HMI(Human-Machine Interface) studies show that drivers with vision or motor impairments value situational-awareness aids—lane-keeping and collision alerts—more than full autonomy, and that usability improves with customisable alerts you can see, hear, and feel (high-contrast palettes, scalable text, adaptive brightness, voice + haptics). While standards such as ISO 15005, SAE J2364, and NHTSA glance-time limits exist. And since most research test only one feature at a time and rarely include drivers with vision impairment, the field still has no comprehensive benchmark for end-to-end dashboard accessibility.

Implications for Design Solutions
Base on literature review, competitive analysis, and design guideline, our solution/design needs:
- Prioritise alerting and multimodal feedback (voice + haptic + high-contrast visuals) rather than autonomous take-over.
- Align with existing automotive HMI standards (ISO 15005, SAE J2364) while extending them with vision-specific settings (colour-blind palettes, glare reduction).
- Include real low-vision drivers in usability testing to close the validation gap and generate repeatable metrics (e.g., glance duration, task-success in night-drive scenarios).
