Every screen captured from the running Kotlin and Jetpack Compose build on a Galaxy S25 Ultra — a live Filament 3D vehicle model, real OpenStreetMap charging data, and an assistant that shows its working. This is the mock build: a physics-based simulator stands in for vehicle telemetry, and there is no connected car behind it. Use the arrow keys to step through, or click any screen to open it full size.
← Back to case studyThese are device captures, not mockups — but they come from the mock flavour. The vehicle is rendered live with Google Filament, and a physics-based simulator produces the telemetry, which is why range drifts between captures. The network layer that would talk to a real vehicle is unfinished.
Screen 7 is the one that matters most. Every AI answer carries the line “Based on: Battery 76% · Outside 8°C · Recent efficiency” — provenance is modelled as part of the type, so the interface cannot display a claim it can't substantiate.
The charging map is real OpenStreetMap data with live station pins, not a placeholder image.
Taken verbatim from core/designsystem. A light pistachio canvas with deep forest green — chosen for glanceability in a bright cabin, where a dark UI reflects badly.
Outfit for display, Inter for body and telemetry.
