Input device using eye tracker in human-computer interaction

This paper describes the development of the eye-gazing input system using the eye tracking system. The eye-gazing input system consists of the subsystem that detects the user's eye movement and the subsystem that calculates the coordinate of the mouse pointer from the eye movement patterns. This paper mainly describes the algorithm to calculate the coordinate of pointer from eye movements and the usability of the input system with respect to the configuration of a selected object. The usability of the developed input system using eye movement is discussed by comparing it with the computer mouse, which is one of the ordinary input devices. In this investigation, the size, moving distance and moving direction are considered as the configuration of the objects, and the effect of the configuration of buttons on pointing time using an eye-gazing input system is analyzed.
