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
