Why visual HMI?

Security - driver can keep the eyes on the road while reading an information Relaxed vision - no/low accommodation, excellent perceptibility Low distraction - relevant and intuitive information about driving and ADAS Fast information flow - direct relation between displayed info and environment.

Why Audio HMI?

The human ear is always active.

The ear is permanently listening in all directions.

So far the acoustic channel is hardly used for automotive HMI.

Customer Research – Dynamic Sound Evaluation

Page 19

Informative aspect of warning is significantly improved Dynamic sounds created by Object Based Audio are easier to locate. ADAS use cases can benefit from this technology.

Semantic evaluation of soundsDynamic (moving) sound objects evaluation

Conclusion

Immersive audio HMI is a new dimension of augmented reality in addition to head-up display HMI

Multimodal HMI is an intuitive way for relevant information about driving environment, especially for dynamic objects

Visteon innovation lab framework enables this functionality in the vehicle
