Influence mechanism of the layout attributes on the effects of the eye-gaze interaction

Eye-gaze interaction is one of the promising interactive modes with the help of human nature. The Eye-gaze interface is composed of multiple functional elements, and users need to navigate and gaze between multiple elements due to the impact of tasks. The correlation between layout and performance has become one of the key criteria for optimizing the design of gaze interfaces. The present study constructed an eye-gaze interactive task environment on the basis of Tobii X2-30 and Tobii studio, selected the optimal parameters for the area of focus and gaze duration so as to ensure the performance, and discussed the influence mechanism of the layout attributes on the effects of the eye-gaze interaction from the aspects of familiarity, interference and vectoring. The results show that familiarity, interference and distance have significant influence on the eye-gaze interactive effectiveness, but the direction tendency is not obvious to the effect, which provide design advice for the eye-gaze interface layout.
