Questions
Why doesn't my controller vibrate here?
Rumble needs browser support. Chrome and Edge play it for most controllers; Safari and Firefox vary. A USB cable also helps, since some Bluetooth setups don't pass rumble through.
What's the difference between the two motors?
Most controllers have a heavier motor on the left for strong, low rumble and a lighter one on the right for quick, high buzz. The DualSense uses haptic actuators instead, but browsers drive them the same way. Testing each side alone shows if one has failed.
Can I test the DualSense haptics and adaptive triggers?
Browsers play the DualSense's rumble through its haptic motors, but not the detailed haptics or adaptive trigger resistance games use. Those need deeper access we are working on.
