# Control with Face

On iPads or iPhones with "Face ID" or newer iPads with at least an M1 processor, you can control SongBook+ with facial gestures.

If you want the control to work even in less favorable lighting conditions, it should definitely be a device with "Face ID". Face ID can scan your face in 3D with an infrared camera and therefore works much more reliably than the normal front camera.

SongBook+ recognizes 9 different facial gestures:

* Close left eye
* Close right eye
* Raise both eyebrows
* Smile
* Open mouth
* Move jaw to the left
* Move jaw to the right
* Pucker lips
* Puff cheeks

The settings for controlling with facial expressions can be found in the "Remote Control" group.
