Method for measuring the position of the users visual fixation point on the surface of a computer screen, system for the implementation of this method and practical applications of this method
The manner of measuring the location of users eyesight fixation point on the computer screen surface based on illuminating the eye surface, monitoring the eye with a camera and analysing light reflecting from the pupil surface is characterized by the fact that sources of illumination are installed in the camera axis, and in corners of computer monitor and/or somewhere near them. This light is an infrared light and depending on features characteristic for the eyes of the user, sources of illumination are turned on or turned off in sequence or jointly, and then, constellations of reflections from pupils surface are recorded in camera image, whereas the camera image is transferred to undergo processing by the computer and by software.
