Vision theory guiding web communication

Eye movements, EMs, are one important component of vision: only specific regions of the visual input are fixated and processed by the brain at high resolution. The rest of the image is viewed at lower and coarser resolution by the retina, but the image is still perceived and recognized uniformly and clearly. We embodied this sampling characteristic of human vision within a computational model, A*, based on a collection of image processing algorithms that are able to predict regions of visual interest. Several web-related applications are presented and discussed in this paper.
