How can drivers manage calls safely across touchscreen, steering-wheel controls, voice, and phone states?
Mapped the full call journey across touchpoints to create a consistent, low-distraction interaction model.
Touch Points

System-level interaction
Designed a shared call-state model across multiple touchpoints, allowing users to accept, reject, minimize, and continue calls without losing context.
The system-level popup could collapse into a persistent smart capsule, while detailed actions remained available in the phone app.
