Abstract
The advantages of curved screen displays find their place in populations everyday life, therefore it is important to adapt the existing eye tracking systems for estimating the gaze point on a curved screen. In this paper we present a curved screen based gaze point estimation model. This model provides methods for estimating the gaze point position by eye rotation angles, and also transforms flat screen based relative coordinates into curved screen based relative coordinates. The model was validated by using a flat screen based eye tracking system for a gaze point estimation on a curved screen. The eye rotation angle, distance to the screen and gaze point location’s influence were modelled in this paper as well. The results of these experiments prove the up to 4% increase of gaze point estimation accuracy by using the proposed model, by comparing the flat screen mode with the curved screen. However the results found are significant only if the distance to the screen is less than 0.5 of curved screen radius.
