Recording

Your camera stays off until you start it.

Keep your hand inside the dashed square, with a plain background behind it if you can.

1Teach your own AI optional

Optional: hand tracking works right away. To build your own AI instead, hold each button while making that shape. Move your hand around a little: closer, farther, tilted. Aim for 60+ samples of each.

On a keyboard you can also hold R, P or S.

2Train the model

A small convolutional network learns from your samples. Takes about 10–30 seconds.

3Play

Hand tracking finds the 21 joints of your hand and checks which fingers are straight. No training needed.
