Japanese Patent JP6958507
Kind Code:
B2
Abstract:
A gaze detection apparatus performs a calibration operation including displaying a target image in multiple positions on a display screen sequentially, setting, in the display screen, corresponding areas corresponding to the target images displayed on the display screen sequentially, and calculating positional data of points of regard in display periods in which the respective target images are displayed; determines, with respect to each of the target images, whether the positional data of the point of regard that is calculated in the calibration operation is present within the corresponding area; when the number of valid target images that are the target images on each of which it is determined that the positional data of the point of regard is present within the corresponding area is at or above a threshold, outputs the positional data of the points of regard of the valid target images as calibration data; and, when the number of the valid target images is under the threshold, causes the calibration operation to be repeated.
