Claim 3:
4. The method according to claim 3, wherein the coordinate prediction model is obtained by:
constructing an initial coordinate prediction model for each of the subspaces;
obtaining a labeled training data set for the subspace, the labeled training data set including a plurality of groups of training data that each include: a user image sample of a test user and a screen coordinate label corresponding to the user image sample, and the training data being labeled with the screen coordinate label; when the user image sample is collected for each of the subspaces, eyes of the test user are in that subspace; and the screen coordinate label represents screen coordinates corresponding to the gaze position of the test user on the display screen when the user image sample is collected, and the user image sample includes a global image sample, a head image sample, and an eye image sample;
inputting the labeled training data set into the initial coordinate prediction model to obtain a prediction result; and
adjusting parameters of the initial coordinate prediction model by comparing the obtained prediction result with a labelled value, until the model converges to obtain the pre-trained coordinate prediction model.
