Driver Assist UI — Canberra J4
Human-centred ADAS interface design for Australian road conditions — lane assist, adaptive cruise, driver monitoring, and contextual EV behaviour. Designed for in-vehicle clarity and safety.
Overview
Canberra J4 focuses on recasting driver-assist interactions for real-world Australian scenarios — bright daylight, highway merge patterns, and EV-specific regenerative braking prompts. We mapped user journeys, edge-case alerts, and multimodal feedback for glanceable controls.
Scope
HMI flows, alert taxonomy, visual hierarchy, tactile & audible layering, and localisation for AUS standards.
Deliverables
Prototype screens, interaction specs, accessibility report, and test scripts for instrument cluster and centre display.
Timeline
8–12 weeks: research, concept, iterative prototyping, and validation drives in ACT and NSW corridors.
Key features & interaction patterns
- Adaptive Alerting: Priority-led visual signals with progressive escalation and repeat suppression logic.
- Driver Monitoring: Face-aware attention prompts (glance-based) and configurable sensitivity for long-distance driving.
- EV-aware Modes: Regeneration and range-aware suggestions integrated with assist behaviour.
Interaction patterns — details
Gallery — screens & prototypes
Instrument cluster — lane assist state
High-contrast lane overlay with trajectory preview and tactile confirmation area.
Centre display — contextual prompts
Contextual hints for EV range and assist re-engagement.
Driver monitoring
Subtle visualisation for attention with privacy-preserving overlays.
Design lead — Canberra sessions
Local workshops led by our UX researcher — contextual interviews and in-vehicle validation drives to refine assist behaviour.
Research & validation
Pilot testing in ACT corridors measured glance time, alert response, and lane-keeping correction rates. Below: selected metrics from validation drives.
| Metric | Baseline | After J4 UI | Delta |
|---|---|---|---|
| Average glance time to cluster (ms) | 680 | 420 | -38% |
| Missed alert escalation rate | 12% | 4% | -66% |
| Lane correction interventions/hour | 2.1 | 1.3 | -38% |
