Designing Haptics
Use short pulses for taps and longer pulses (with shake) for alerts. Keep patterns under 3s. Avoid vibration acknowledgments for agent messages.
Patterns
- Tap: 60–120ms pulse
- Double-tap: 2x 80ms separated by 120ms
- Hold accept: 300–500ms ramp-up
- Decline: 2x 200ms with 150ms gap
