Description

Use slightly bigger buttons and enlarge the clickable area of your interactive elements to the maximum.

Do not exaggerate the overall size, though, because larger targets are effective up to a point, after which they hit a plateau and will only make users ignore other important elements on the page.For example, Duolingo uses a very large button on the homepage that is easy to click.

Today’s product experiences are becoming blazing fast.We expect speed. We demand no more than a few minutes for Uber car arrivals, same-day deliveries from Amazon, instant upload time of huge images on Facebook and not a single millisecond of buffering when watching a Youtube video.Our experiences require speed of use.Speed of use is a usability trait describing the minimal timeframe in which users accomplish a given task. This includes the actions that lead to the task but also the time it takes users to recover from errors.Speed of use, however, should not be confused with ease of use, which refers to how easy and intuitive an interface/flow/action is without external support. Both are important and should be treated harmoniously by overlapping their key components.Here are 5 rules you should consider for improving speed of use.

Rule 1: Respect Fitts’s LawFitts’s law is a model of human movement for quantifying the difficulty of selecting a target.First devised in 1954 by Paul Fitts, the law states that the time required to move to a target area is a function between the distance to the target and the size of the target. Basically, in terms of interaction design, the closer and larger the target area, the faster it is to reach it with a pointing object, be that the mouse pointer or the fingertip.
