HMIs don’t function in isolation. Their efficacy is amplified when they’re integrated seamlessly into the broader AV ecosystem.

Integration with Vehicle’s Decision Systems

An HMI that can effectively communicate the vehicle’s decision-making process to passengers enhances trust. For instance, if an AV decides to change lanes or reroute, the HMI should offer insights into why such a decision was made. Patenting such integrative solutions requires startups to highlight the synergistic benefits they bring to the table.

Collaboration with External Infrastructure

Future urban landscapes might feature traffic lights, signs, or even pedestrian pathways that communicate directly with AVs. HMIs that can relay this external information to passengers in real-time can elevate the autonomous driving experience.
