Hi there To build an on-device UI for a 47 mm AI smartwatch, the most critical part is creating a round-display interface that works seamlessly across touch, crown, buttons, gestures, and voice—without compromising performance or battery life. I’d approach this as an embedded UI engineering task, not just visual design. That means structuring the UI around glanceable layouts, deterministic input handling, and clear AI states (listening, thinking, speaking), using a lightweight framework such as LVGL or Qt Embedded. Animations and transitions would be tuned for 60 Hz when active and gracefully degrade in low-power or AOD modes. The focus will be readability, responsiveness, and power-aware behavior across watchfaces, health dashboards, quick actions, and system screens. UI architecture will be modular so screens, gestures, and AI flows can evolve as hardware and firmware mature. My process is to lock navigation and input models first, then implement core screens, followed by performance tuning and visual polish. Once scope and hardware constraints are finalized, I’ll provide an exact timeline and milestone-based budget.
