Threshold for pose estimation?

[harshithdwivedi]

Hi, are there any thresholds or calculations that you've made on the pitch, yaw and roll to determine where the person is looking at?

I'm not sure how to go about to calculating the direction of the gaze from the pitch, yaw and roll.

Make sure the face is facing the screen, and the angle of the three types is less than 45 degrees, which can be regarded as paying attention to the screen. Use your head and imagination more！
