[Feature Request]: Gaze Estimation Demos questions about open_model_zoo HOT 2 OPEN

Hi. Sorry, I can't describe the training dataset.

Hi @adamswsk,

I was involved in the development of the model. But since it was more than 5 year ago, and I am not with OpenVino team anymore, I only have a vague recollection of what the dataset looked like.

Basically the setup was as follows. The participants were seated at some fixed distance in front of a rectangular board (like a blackboard in school) with a grid of points. The center of the board was at the same height as the eyes of the participants. The camera was attached to the center of the board, and directed at the center of participant's heads, so that optical axis of the camera intersected (roughly) the line between the eyes. The ground truth for the gaze vector was determined by computing the direction of a vector between participant's eyes and the point the participant was looking at. The head poses of the participants had some variety, but the gaze vector didn't depend on it: the gaze vector for some point in the board was the same regardless of the head pose.

Hope it helps.
