+On the other hand, it should not be difficult to implement the training part.

 1. `python app.py`
 1. Put your **right hand** in front of the camera. The pre-trained model is for left hand, but the input would be flipped internally.
 1. Press `ESC` to quit.

 We found that the model may fail on some "simple" poses. We think this is because such poses were no presented in the training data. We are working on a v2 version with further extended data to tackle this problem.
