# Apple HIG: Inputs

Check for `.claude/apple-design-context.md` before asking questions. Use existing context and only ask for information not already covered.

## Key Principles

1. **Support multiple input methods.** Touch, pointer, keyboard, pencil, voice, eyes, hands, controllers. Design for the inputs available on each platform. On iPadOS, support both touch and pointer; on macOS, both pointer and keyboard.

2. **Consistent feedback for every input action.** Visible, audible, or haptic response.

3. **Standard gestures must behave consistently.** Tap to activate, swipe to scroll/navigate, pinch to zoom, long press for context menus, drag to move. Don't override system gestures (edge swipes for back, Home, notifications).

4. **Use standard recognizers; keep custom gestures discoverable.** Apple's built-in recognizers handle edge cases and accessibility. If you add non-standard gestures, provide hints or coaching to teach them.

5. **Apple Pencil: precision drawing, markup, and selection.** Support pressure, tilt, and hover. Distinguish finger from Pencil when appropriate (finger pans, Pencil draws).

6. **Support Scribble in text fields.** Users expect to write with Pencil in any text input.

7. **Keyboard shortcuts and full navigation.** Standard shortcuts (Cmd+C/V/Z) plus custom ones visible in the iPadOS Command key overlay. Logical tab order.

8. **Respect the software keyboard.** Adjust layout when keyboard appears. Use keyboard-avoidance APIs.

9. **Game controllers: MFi controllers with on-screen fallbacks.** Map to extended gamepad profile, sensible defaults, remappable. Always offer touch or keyboard alternatives.

10. **Pointer and trackpad: native feel.** Hover effects, pointer shape adaptation, standard cursor behaviors. Two-finger scroll, pinch to zoom, swipe to navigate.

11. **Digital Crown: primary scrolling and value-adjustment input on watchOS.** Scrolling lists, adjusting values, navigating views. Haptic feedback at detents.

12. **Eyes and spatial (visionOS): look and pinch.** Generous hit targets (eye tracking is less precise than touch). Avoid sustained gaze for activation. Direct hand manipulation in immersive experiences.

13. **Focus system: critical for tvOS and visionOS.** Predictable focus movement. Every interactive element focusable. Clear visual indicators (scale, highlight, elevation). Logical focus groups.

14. **Siri Remote: limited surface.** Touch area for swiping, clickpad for selection, few physical buttons. Keep interactions simple.

15. **Gyroscope, accelerometer, UWB: use judiciously.** Suits gaming, fitness, AR. Not for essential tasks. Provide calibration and reset. For UWB, communicate distance and direction with visual or haptic cues.

## Output Format

1. **Input method recommendations by platform** and how they interact.
2. **Gesture specification table** -- standard and custom gestures with expected behaviors.
3. **Keyboard shortcut recommendations** following system conventions.
4. **Accessibility input alternatives** for VoiceOver, Switch Control, etc.

## Questions to Ask

1. Which platforms and input devices?
2. Productivity or casual app?
3. Custom gestures in the design?
4. Game controller support needed?
