Experiences on Attention Direction through Manipulation of Salient Features

In this paper we present a study on the impact on user’s fixations by localized modifications of the color properties of an image. We outline the technique used to influence the fixations of the participants, where it succeeded and where it failed. The question we address is whether pixel-wise modifications are sufficient to influence the order of fixations of the users and how strong this effect is. We developed a technique that performs localized adjustment in value, saturation and hue and conducted a user study with an eye tracker to asses its effectiveness. The results of our study imply that one can effectively influence the order and the duration of fixations of users based on localized adjustments.
