  • Using Fitts's Law to Make Links and Buttons Easier to Click

    Fitts's Law describes how long time it takes to click a target, based on the distance to the target and its size. Use this information to make buttons and links faster to click.

  • 3 Ways to Onboard New Users

    How to familiarize users with new user interfaces? Onboarding techniques include feature promotion, customization, and instructions. All must be kept simple.

  • UI Modes and Modals

    Modes can be a hidden state and lead to user errors. But they can also make a user interface more efficient by allowing the same action to have different results, depending on the situation.

  • Direct Manipulation in User Interfaces

    Direct manipulation is an interaction technique in graphical user interfaces where users move depictions of objects around and get immediate feedback about their actions and the outcome of these actions.

  • UX vs. UI

    User experience and user interface are highly related. Both are important, but what's the difference between UX and UI? (Often confused!)

  • When Is It OK to Be Inconsistent in User Interface Design?

    Consistent design enhances learnability and is usually best for usability. But if the problem you're solving is sufficiently different, then inconsistency may be better.

  • UX Animations

    Animations can make user interfaces both easier and nicer to use, but the timing has to be right, as we demonstrate in this video. Many other details also contribute to the quality of animation in the user experience.

  • Augmented/Virtual Reality vs. Computer Screens

    Will 3D user interfaces like VR and AR replace flat screens, and how should UX designers prepare for these technologies?

  • Virtual Tours

    User interfaces that simulate a presence in a physical space allow people to tour an environment without travelling there, but were mostly considered secondary by our research participants, partly because it’s currently slow and confusing to navigate virtual tours.

  • Login Walls

    Demanding that users create a new account before they are able to access a website or mobile app is only justified in rare cases. Usually, people go away, rather than scale a wall placed between them and your offerings.

  • Learnability vs Efficiency in User Interface Design

    Two of the most fundamental usability metrics are learnability (the user's ability to use a new design they have not seen before) and efficiency (the speed with which people do tasks after they have learned the interface).

  • Better Forms Through Visual Organization

    How to organize and lay out your form fields and their labels to make data entry easier for users.

  • CX vs. UX

    Customer Experience (CX) and User Experience (UX) are two common terms that mostly mean the same thing but have different connotations. Whatever your preferred term, it's important to consider design at 3 levels of experience.

  • Dualities of User Experience (Jakob Nielsen keynote)

    Many issues in the user-experience field don’t have a simple answer. Rather there’s a tension between two good answers that are often polar opposites. Both extremes can be useful perspectives, and both have their advocates when people debate UX. How do we resolve these differences? This was Jakob Nielsen's keynote at the UX Conference in Las Vegas.

  • Disclosing Password Constraints in the UI

    Having to register for websites, services, or apps is already annoying enough for users. But complications compound when they are faced with hidden requirements for what constitutes an acceptable password.

  • Steering Law for Cursor and Mouse Movements in a GUI Tunnel

    In a graphical user interface, having the user move a cursor within a narrow path (e.g., in a hierarchical menu or a slider) follows a strict law for how easy or difficult it is to do, depending on the specifics of the GUI.

  • Simple Design Is Relative

    Simplicity depends on the capacity of the information channel and what's simple for one device, can be primitive or intricate for another, since screens are information channels with a limited capacity. When you're designing for multiple devices, don't go by common cliches like "simple is good."

  • How to Empathy Map

    A 5-step process for creating empathy maps that describe user characteristics at the start of a UX design process.

  • Gamification in the User Experience

    Gamification is the usage of game mechanics in nongame contexts, such as mainstream UX design. The most successful implementations of gamification begin with a learner-centered mindset.

  • Fitts's Law

    Fitts's Law describes how long it takes a user to hit a target in a graphical user interface (GUI) or other design, as a function of size and distance. Understanding this law helps us design better buttons, forms, lists, and other interactive elements.
