Overview:

Android 12 expands the tools for creating informative haptic feedback for UI events, immersive and delightful effects for gaming, and attentional haptics for productivity.

Actuator effects

Android 12 adds expressive effects like low tick that take advantage of the broader frequency bandwidth of the latest actuators. Game developers can now access multiple, different actuators independently in game controllers to deliver the same effect synchronously or different haptic effects on multiple actuators.

These APIs are available to try on Pixel 4 devices, and we're continuing to work with our device-maker partners to bring the latest in haptics support to users across the ecosystem.

Audio-coupled haptic effects

Android 12 apps can generate haptic feedback derived from an audio session using the phone's vibrator.

Proposed Action:

Research usefulness.

Looks like it is done mostly for Gaming, some APIs only available on Pixel 4 device.
