Hi @RichardoMrMu , you need to do the camera-screen calibration to get the values in camera_transoformation. We wrote such information in the "A.3 Dataset Pre-processing" of the "Appendix" section in...

Hi, I updated our [project webpage](https://ait.ethz.ch/projects/2020/ETH-XGaze/) and you can find a short video about the data collection. I hope it is helpful for you. Kind regards, Xucong

Hi, we did not use the multi-view stereo to get the 3D position of eye, although that will be optimal. We use the fitting the 3D face model (landmarks) to...

Hi, Sorry for the late reply. As we wrote on the registration page: "Please take it seriously since it is the part of legal agreement." The registration is serious for...

Hi, I am sorry for the late reply. The camera information affects the image cropping during the data normalization. However, you can change the "[focal_norm](https://github.com/xucong-zhang/ETH-XGaze/blob/df0f015e74f8845a60c010a7034e47cf5fdcd0e8/normalization_example.py#L41)" or "[distance_norm](https://github.com/xucong-zhang/ETH-XGaze/blob/df0f015e74f8845a60c010a7034e47cf5fdcd0e8/normalization_example.py#L42)" to get the...

Hi, the values of head pose and gaze direction are in radians as pointed by @VeruGromnicova. @mahdip72 Both head pose and gaze directions are in the camera coordinate system and...

Hi, I added a code example "[normalization_example.py](https://github.com/xucong-zhang/ETH-XGaze/blob/master/normalization_example.py)" which does the data normalization frow raw to the normalized data. Basically, you need to get the [face centre as the gaze origin](https://github.com/xucong-zhang/ETH-XGaze/blob/483c5ca2c39c84a51324496142a1f5982dd1c155/normalization_example.py#L52...

Hi, sorry for the late reply. The head rotation "hr" is not a pointing vector. It is the rotation vector on roll, yaw and pitch axis. If you want to...

Hi, That is a very interesting question. The short answer is yes, you should always use gc_normalized = np.dot(R, gc_src) for all data processing. The long answer is here: We...

Hi, The face_gaze means the gaze direction of the face image. It is centered on the face. The 3D landmarks are described in the paper. It is fitted 3D face...
