Learn how to use the Principles of Fitts’s Law to improve your UX/UI Designs 🔥🔥 FREE PDF Cheatsheet! Fitts’s Law was introduced by a psychologist Paul Fitts in 1954. The law has a big importance in human-computer interaction and defines the correlation between a cursor movement or a touch gesture and an interface element. Overview: What is Fitt's Law? The time required to acquire a target area is a function of the ratio between the distance to and size of the target. How does it apply to User Interface design? - Interactive elements should be distinguished from non- - Sometimes a designer can predict where is the prime pixel (the point from which the user will continue interaction). Position more important and related UI elements closer to this pixel. - Magic pixels are the furthest areas from the prime pixel. Avoid placing anything important into these areas. - The outer edges and corners of the UI can be reached with greater speed than anywhere else in the display, due to pinning action of the screen. - UI element is easier to select if its size is increased or the distance to it is decreased. Practical Tips for Using Fitts’s Law: - Reduce the distance from one point to the next in UI and make the target object large enough to enable prompt detection and selection of interactive elements without sacrificing accuracy. - Make every combination of a checkbox/radio + label as the entirely clickable area. - Don’t go overboard with putting elements too close to each other or making it too big. Follow visual balance and hierarchy, give the user a breathing room. - Establish a meaningful visual hierarchy in UI elements and content. - Appropriate grouping is important in articulating functionality. - Provide enough space between elements for error-prevention. #ux #uxdesign #ui #uidesign #uxlaws #fittslaw #productdesign #uxprocess #userexperience #design #designthinking #research #userresearch #uxresearch #usertesting #usability #usabilitytesting #prototyping #agile #mvp #startup #digital #visualdesign #graphicdesign #business #startup
