You can optionally output the estimated information to a .csv file. We intended to have similar output data with Pupil Labs.

CSV file

The content of output .csv file are following:

• timestamp - timestamp of the source image frame
  
• index - frame number of input video or camera
  
• face_id - face identification generated by OpenFace with tracking
  
• confidence - face and facial landmark detection certainty ranges from -1 to 1, provided by OpenFace. A value of -1 indicates no confidence. 1 indicates perfect confidence.
  
• gaze_2d_x - x position in the estimated gaze in normalized coordinates. The coordinate is based on the screen such that the origin (0,0) is the top left and (1,1) is the bottom right
  
• gaze_2d_y - y position in the estimated gaze in normalized coordinates. The coordinate system is the same as for norm_pose_y
  
• face_center_3d_x - x center of face in the camera coordinate system
  
• face_center_3d_y - y center of face in the camera coordinate system
  
• face_center_3d_z - z center of face in the camera coordinate system
  
• gaze_3d_x - x position of the 3D gaze direction vector in the camera coordinate system
  
• gaze_3d_y - y position of the 3D gaze direction vector in the camera coordinate system
  
• gaze_3d_z - z position of the 3D gaze direction vector in the camera coordinate system
  
• left_eye_3d_x - x center of left eye in the camera coordinate system
  
• left_eye_3d_y - y center of left eye in the camera coordinate system
  
• left_eye_3d_z - z center of left eye in the camera coordinate system
  
• right_eye_3d_x - x center of right eye in the camera coordinate system
  
• right_eye_3d_y - y center of right eye in the camera coordinate system
  
• right_eye_3d_z - z center of right eye in the camera coordinate system
