Abstract

In the present specification, a method and an apparatus for generating ocular movement ability information are disclosed. The method for generating ocular movement ability information, according to the present specification, is a method for generating ocular movement ability information using a device including an RGB camera, a depth sensor, and an ocular tracking sensor in a housing of a predetermined shape mounted on a head of a subject, and may comprise: (a) calculating, by a processor, coordinates for a plurality of grid points in image data obtained by photographing an ocular movement indicator input from the RGB camera; (b) receiving, from the ocular tracking sensor by the processor, a measurement value for the gaze direction of one of the eyes of the subject of which the field of view is blocked, and storing the measurement value; (c) storing, by the processor, timing (hereinafter, referred to as "timing information") at which one of the eyes of the subject of which the field of view is open fixates at the grid points included in the ocular movement indicator; and (d) calculating, by the processor, a gaze error of the subject with respect to each of the grid points by using distance information between the subject and the indicator input from the depth sensor, the timing information, and gaze tracking information.
