Gazing point estimation device.

摘要

The device described enables calibration data indispensable for calculation of a gazing point to be fetched and also an estimation of a gazing point to be determined by calculating a pupil center position through image-processing data obtained via a camera, increasing the brightness of a gazing point on a display screen according to the calculated values and calibration data, measuring the change in pupil area at the moment, establishing a correlation, thereby improving the operability of a gazing point estimation system. <IMAGE>
