Hierarchical Attention Focusing and a Display Method for Small Mobile Devices

We propose a model of hierarchical attention focusing and its application to a display method for small mobile devices. First we point out that the visual resolution is low when the attended area is broad and is high when the attended area is narrow. Then we propose a model to obtain saliency which expresses tendency of attracting human attention. Combining these we construct a model which controls attention movement, especially which predicts how attention is focused to an interest object. Based on the model we propose a method to display a large scale image in a small screen of small mobile devices as mobile phones. In this method a region of interest (ROI) is detected using the saliency model and the region is successively zoomed in as if attention is hierarchically focused into the region.
