    Despite great diversity in the workflows and end users supported by complex applications, these 8 design guidelines are generally applicable.

  • The Visual Principle of Scale in User Interface Design

    Users pay more attention to big things than to small things, and this design principle can be used to prioritize a user experience design, such as a web page or application screen.

  • State-Switch Controls: The Infamous Case of the "Mute" Button

    On–off controls that switch between two different system states need to clearly communicate to users both the current state and the state the system will move to, should the user press that control.

  • Myths About Complex App Users

    Three stereotypes explain much resistance to improving the usability of complex applications for domain-specific tasks: that people like the old ways, that they are experts in the existing UI, and that training will make up for bad design. All are misleading.

  • Virtual Reality and User Experience

    Virtual reality (VR) user interfaces are currently more difficult for users to manipulate than a traditional GUI, partly because of more degrees of freedom and partly because VR is still new, so people have less experience using it. Advice for how to employ usability studies to alleviate this problem.

  • Mask Interaction Delays with Progress Indicators

    In case of slow response times in a user interface, indicate that the wait time will soon be over by showing an animation. For longer delays use a percent-done indicator.

  • Ephemeral Web-Based Applications

    Usability tests of 46 Flash applications identified basic issues related to the ephemeral nature of Web-embedded apps. Some findings restate old truths about GUIs; others reflect the Net's new status as nexus of the user experience.

  • Error Message Guidelines

    Established wisdom holds that good error messages are polite, precise, and constructive. The Web brings a few new guidelines: Make error messages clearly visible, reduce the work required to fix the problem, and educate users along the way.

  • Customers as Designers

    The Internet is undoing the industrial revolution's emphasis on mass-produced products; now everybody can get exactly what they want. But designing the product you want is hard, and current design interfaces are not good enough for novice designers (i.e., all normal customers).

  • Reset and Cancel Buttons

    Most Web forms would have improved usability if the Reset button was removed. Cancel buttons are also often of little value on the Web.

  • Saying No: How to Handle Missing Features

    Instead of making users wander indefinitely and frustratingly around a site looking for something that's just not there, tell them if it lacks a frequently requested feature

  • When to Open Web-Based Applications in a New Window

    Applets are divided into two categories: functionality applets that need to open in a new window and content applets that should stay on the browser page.

  • The Difference Between Web Design and GUI Design

    Designing for the Web is different from traditional user interface design. Fundamentally, the designer gives up a lot of control to the user - get used to it: WYSIWYG is dead

  • Response Times: The 3 Important Limits

    How users react to delays in a user interface, whether website or application. The 3 main response time limits are determined by human perceptual abilities.

  • A Layered Interaction Analysis of Direct Manipulation

    The concept of direct manipulation is usually viewed as a single characteristic of a class of interaction styles. Here, direct manipulation is analyzed according to a detailed layered interaction model, showing that it has quite different effects on the dialogue on the different levels. In particular, the "no errors" claim may be true at the syntax level but not at several of the levels above or below that level. Furthermore, a unified framework is presented for conceptualizing Direct Manipulation, What You See Is What You Get (WYSIWYG), Transparency, Immediate Command Specification, Arcticulatory Directness, and Computational Appliances according to a layered interaction view.

  • Assessing the Usability of a User Interface Standard

    User interface standards can be hard to use for developers. In a laboratory experiment, 26 students achieved only 71% compliance with a two page standard; many violations were due to influence from previous experience with non-standard systems. In a study of a real company's standard, developers were only able to find 4 of 12 deviations in a sample system, and three real products broke between 32% and 55% of the mandatory rules in the standard. Designers were found to rely heavily on the examples in the standard and their experience with other user interfaces. Thovtrup, H., and Nielsen, J. (1991). Assessing the usability of a user interface standard. Proc. ACM CHI'91 Conf. Human Factors in Computing Systems (New Orleans, LA, 28 April-2 May), 335-341.
