Abstract

A rendering optimizer captures content engagement feedback associated with a first interval during which electronic content is presented with a first set of rendering parameter values. The rendering optimizer adjusts at least one rendering parameter value of the first set of rendering parameter values by a step amount in a first direction to create a second set of rendering parameter values and captures content engagement feedback associated with a second interval during which the electronic content is presented with the second set of rendering parameter values. The rendering optimizer further adjusts the rendering parameter values to determine they result in an improvement in reading immersion.
