To unify multi-input interactions in HarmonyOS, generate a phase-based interaction plan that defines consistent event models, device capability boundaries, and focus contracts for touch, mouse, keyboard, and stylus inputs. This prevents inconsistent UX behaviors across different devices.

Hover feedback breaks in HarmonyOS when device-specific capability boundaries are undefined. Establishing explicit interaction routing contracts and verification matrices for mouse hover and right-click context menus ensures predictable behavior across phone, tablet, and 2-in-1 devices.

Implement keyboard focus navigation by generating structured REQ, DEV, FIX, and VAL outputs that define focus order, direction key routing, and shortcut constraints. This establishes a clear focus contract ensuring keyboard interactions remain regression-safe alongside touch workflows.

Yes, you can separate stylus press and hover input from touch events by applying a multi-input interaction unification plan. It defines explicit device constraints and capability boundaries to distinguish stylus behaviors while keeping existing touch workflows intact.

The best way to prevent conflicting context menu shortcuts is to produce a phase-based interaction plan with explicit routing and focus contracts. This plan covers applicable input combinations and includes verification matrices to identify and resolve shortcut conflicts.

Yes, specifying device constraints is required when adapting HarmonyOS UI for multiple input methods. The interaction plan must establish capability boundaries for what must work or degrade by device type, covering phone, tablet, 2-in-1, and TV primary input variations.
