UDC 519.683.8:519.6 About one Model of Computer Control on the Basis of Gaze Tracking I. M. Gostev, E. A. Sibirtseva National Research University Higher School of Economics 20, Myasnitskaya str., Moscow, Russia, 101000 The methodology of human-computer interaction based on the determination of the eyeball position and its movement direction. <...> For interference and noise elimination from extraneous lighting devices infra-red illumination which allows receiving only one highlight on a cornea from an infra-red light-emitting diode is used. <...> Thus the entrance video-stream in an infra-red range is processed in real time in two parallel processes. <...> One process is used for definition of position of a highlight from a light-emitting diode on corneas of eyes, another process — for definition of position of a pupil and a direction of its moving. <...> Aggregate of co-ordinates of a highlight of a pupil, position of a cornea and a direction of its moving allow remote to control of the computer. <...> For prevention of loss of “object” the original technique of accumulation of the previous positions of an eyeball and forecasting of a direction of its moving is used. <...> The developed hardware and software system for gaze direction tracking be used as an alternative method of input medium, which is closer to the natural way of interaction with the environment, as well as the only way to work with a computer for the users with reduced mobility. <...> Key words and phrases: gaze tracking, non-command interface, human-computer interaction, image processing, pattern recognition. 1. <...> This also includes non-contact data entry for disabled users; behavior analysis of the human operator for the complex production according to his eye movements; psychological testing and research of mental faculties, and many others, where information can be obtained from the observation of the human pupils and then used [1]. <...> There are also systems such as ”EagleEyes B” [5], where the principle of electrooculography is used, in which electrodes, attached to the user’s head, analyze electromagnetic signals that are sent by the eye moves. <...> Second, they use special hardware devices, which are produced in single units and cannot be recommended for mass use. <...> Based on the above, the purpose of this work is the development of hardware and software for the analysis of eye tracking without the use of special hardware devices. 2. <...> Theoretical <...>
