Product experience:
Fewer notifications
To minimize driver distraction, heads-up notifications (HUNs) in a car have tighter limitations compared to other devices.
HUNs in the car should be actionable and time-sensitive, with an importance level of HIGH or above, and they also must meet one or more of the following criteria:
- Safety-critical
- Driving-relevant
- Communications-related
Less content per notification
Simpler interactions
Awareness of the car’s driving state
Android Automotive OS includes a UX Restrictions Engine, which is a set of rules (configurable by car makers) about what can and cannot happen during particular driving states.
