Haptic Feedback Design for XR

Haptic feedback transforms VR interactions from visual-only events into multi-sensory experiences. This skill covers designing, implementing, and testing haptic patterns for VR controllers, hand tracking devices, and advanced haptic hardware. Good haptics dramatically increase presence, usability, and satisfaction in XR applications.

## Key Points

1. Vary amplitude and frequency — constant vibration goes numb
2. Use short, sharp pulses for events (10-50ms)
3. Use texture patterns for continuous contact (varying frequency)
4. Stronger ≠ better — subtle haptics feel more natural
5. Pair haptics with audio for strongest perception
6. Maximum effective continuous duration: 2-3 seconds
1. Tap (confirmation/selection):
2. Double Tap (important event):
3. Buzz (error/warning):
4. Ramp Up (approaching/loading):
5. Ramp Down (release/fade):
6. Pulse Train (continuous event):
