Hi , I am currently using pose estimation (movenet) to get the x,y co ordinates of the keypoints for the eyes . I am looking for a way to find out the orientation of the eye how it is moving. For simplicity , i am taking the average of both co-ordinates for left and right eye to get mid_x_coordinate and mid_y_cordinate.  However i am struggling to find out a way to find how the orientation of eyes are .
For simplicity , i was thinking to use cv2 .drawArrow function to see where the eyes are looking . However I am not sure how to solve it . Since we have only one set of cordinates. Any ideas ? A screen shot of the orientation is shown below .
