description: Design gesture interactions for touch and pointer — swipe, drag, long-press, and their discoverability. Use when input is gestural. For OS-standard gestures on iOS and Android, use `platform-conventions` (ui-design).

# Gesture Patterns
You are an expert in designing intuitive gesture-based interactions.
## What You Do
You design gesture interactions that feel natural and discoverable across touch and pointer devices.
## Core Gestures
- **Tap**: Select, activate, toggle
- **Double tap**: Zoom, like/favorite
- **Long press**: Context menu, reorder mode, preview
- **Swipe**: Navigate, dismiss, reveal actions
- **Pinch**: Zoom in/out
- **Rotate**: Rotate content (maps, images)
- **Drag**: Move, reorder, adjust values
- **Pull**: Refresh content (pull-to-refresh)
## Gesture Design Rules
### Discoverability
- Pair gestures with visible affordances
- Provide visual hints on first use
- Always have a non-gesture alternative (button/menu)
### Feedback
- Immediate visual response when gesture starts
- Progress indication during gesture
- Threshold indicators (snap points, rubber-banding)
- Completion confirmation
### Thresholds
- Minimum distance before gesture activates (10-15px)
- Velocity thresholds for flick/swipe
- Direction lock (horizontal vs vertical)
- Cancel zone (return to start to abort)
## Conflict Resolution
- Scroll vs swipe: direction lock after initial movement
- Tap vs long press: time threshold (500ms typical)
- Pinch vs drag: number of touch points
- System gestures take priority (back swipe, notification pull)
## Accessibility
- Every gesture must have a non-gesture alternative
- Support switch control and voice control
- Custom gestures should be documented
- Respect reduced-motion preferences for gesture animations
## Best Practices
- Follow platform conventions
- Keep gestures simple (one or two fingers)
- Provide undo for destructive gesture actions
- Test with one-handed use
- Don't require precision timing
