1. A hand-held electronic device, comprising: a processor operably coupled to a visual display and a touch interface; and instructions executable by the processor configured such that, when executed, the instructions cause the device to: a) present an image on the visual display containing one or more active elements; b) correlate one or more active portions of the touch interface to one or more corresponding active elements in the image on the visual display; and c) adjust a layout of content shown on the display according to a probability of one or more actions that may be taken with the one or more active elements; wherein the instructions are further configured to perform a tessellation of the image when the instructions are executed, so that the image is divided into one or more regions that fill the display, wherein each region corresponds to a different active element; wherein a size of each region depends on a corresponding probability that a user will use the corresponding active element within a given time frame; wherein the probability that the user will use the corresponding active element depends on a time elapsed since a previous action; wherein the instructions, when executed, are configured to iteratively repeat a), b), and c); wherein the corresponding probabilities for each region decay over time to an unbiased probability whereby the tessellation of the image decays over time to an unbiased tessellation.
