Abstract
A method for determining a gaze point mapping function includes that: all parameters to be solved in a gaze point mapping function are combined to obtain a parameter vector of the gaze point mapping function, and the parameters to be firstly solved and parameters to be secondly solved corresponding to the parameter vector are determined; the parameters to be firstly solved for a first user are solved according to an eye image of the first user and corresponding gaze point information; solutions of the parameters to be secondly solved for the first user are determined according to the parameter vector which is solved by each of multiple second users respectively; and the gaze point mapping function of the first user is determined according to solutions of the parameters to be firstly solved for the first user and the solutions of the parameters to be secondly solved for the first user.
