I found this video and I thought of sharing it with you, maybe someone will find it interesting and helpful. The software is
FaceTrackNoIR
This is a nice software, although I have a VR but ysing the VR it’s hard to see the keyboard. But with this around 4$ it’s amazing to have your hand free from the mouse and have both hand in the joystick and the keyboard. But you need to set the head movement sensitivity to your liking. But over all I like it and it does the job so I give it a 8/10.
Also they have a good community to support the software
