“…In this study, we hypothesize that by subtly modifying the visual scene, it is possible to drive the observer's attention away from salient distracting locations, enabling the user to find the target faster. Previously, some attempts were made to apply subtle visual content modification for gaze guidance, where color, luminance, spatial frequency, and other domains were modulated [32][33][34][35][36][37][38][39][40][41]. In this work, blur was selected as a domain for modifying visual content, as it was previously shown that blur, although with limitations, can be used for gaze guidance to an extent where the observer does not even notice the modification [42][43][44].…”
