Eye tracking methodology and applications to images and video

Abstract

Our tutorial introduces eye-tracking as an exciting, nonintrusive method of capturing user attention during human interaction with digital images and videos. We believe eyegaze can play a valuable role in understanding and processing (a) huge volumes of image and video content generated as a result of human experiences and interaction with the environment (b) Personalization and in human-media interaction, having access to individual preferences and behavioral patterns would be a key component of such a system. Recent possibilities to seamlessly integrate eye-tracking into laptops and mobile devices opens up a plethora of possibilities for applications that can respond to human visual attention strategies. (c) Visual content design such as in advertising often employs techniques that guide user attention to produce visual impact and elements of surprise and emotion. Eye-gaze has been used as a tool to evaluate different choices of visual elements and their placement. (d) Affective analysis of images and videos is an ongoing and challenging area in multimedia research, show recent results on how eye-gaze and accompanying pupillary dilation information can aid affective analysis. © 2011 ACM.
