Eye Movement analysis with HMMs (EMHMM)

We use hidden Markov models (HMMs) to analyze eye movement data. A person’s eye fixation sequence is summarized with an HMM, and common strategies among people are discovered by clustering HMMs.

Directing User Attention via Visual Flow on Web Designs

​We present an approach that allows web designers to easily direct user attention via visual flow on web designs.

DynamicManga: Animating Still Manga via Camera Movement

We propose a method for animating still manga imagery through camera movements, driven by motion and emotion semantics automatically extracted from the manga.
