Applying Fitts’ Law to Mobile Interface Design, shreds light into one of the essential principle of Human-Computer Interaction – Fitts’ Law. It was proposed in 1954 by Paul Fitts as a metric to quantify the difficulty of a target selection task. Though this is not the only consideration when it comes to design, but it is one of the popular interaction design principle.
In the article, Justin Smith explains various examples and shows how Fitts’ law is applied on design for desktop applications. Further he explains about the same for mobile devices too, where different terms like Thumb Zones, Orientations etc., are considered.
