M3E haptic standards
For a premium "felt" experience, curate haptics by the weight of the interaction rather
than buzzing on everything. Map each interaction to a framework
HapticFeedbackConstants value:
| Interaction | Role | Constant (typical) |
|---|
| Scrolling milestones | Mechanical tick | CLOCK_TICK / SEGMENT_TICK |
| Success / save / commit | Confirmation | CONFIRM (fallback LONG_PRESS) |
| Error / reject | Reject | REJECT |
| Toggle / click | Light tick | VIRTUAL_KEY / KEYBOARD_TAP |
| Long press | Contextual | LONG_PRESS |
| Selection delta (dropdowns, sheets) | Tick per change | SEGMENT_TICK |
Rules
- Always gate haptics behind a user preference. Route every haptic through one helper
that early-returns when the user has haptics off — never call
performHapticFeedback
directly from activities/adapters. Respecting the toggle is non-negotiable.
- Scroll feel: attach a scroll-milestone tick to any list carrying core data.
- Selection feel: fire a tick on each selection delta in pickers/bottom sheets.
- Reserve success/error haptics for genuine commit/failure events, not routine taps.
