First Principles of Interaction Design Revised ExpandedThe following principles are fundamental to the design and implementation of effective interfaces, whether for traditional GUI environments, the web, mobile devices, wearables, or Internet connected smart devices. Help This is a huge revision. I expect I have made mistakes. Please leave corrections and suggestions in the Comments at the end. If you have better examples than Im using, please include them as well, but give me enough information about them, including links or cites, that I can make use of them. This revision features new examples and discussion involving mobile, wearables, and Internet connected smart devices. However, the naming and organization remains the same except for three changes I have shortened the name of one principle to extend its reach Color Blindness is now simply Color and includes more than just color blindness. Ive added one new principle, Aesthetics, and brought back two old principles, Discoverability and Simplicity. I dropped them from the list more than a decade ago when they had ceased to be a problem. Problems with Discoverability, in particular, have come roaring back. What has changed greatly is the level of detail You will find many new sub principles within each category, along with far more explanation, case studies, and examples.

Effective interfaces are visually apparent and forgiving, instilling in their users a sense of control. Users quickly see the breadth of their options, grasp how to achieve their goals, and can settle down to do their work. Effective interfaces do not concern the user with the inner workings of the system. Work is carefully and continuously saved, with full option for the user to undo any activity at any time.

Because an application or service appears on the web or mobile device, the principles do not change. If anything, applying these principlesall these principlesbecomes even more important. I Love Apple, But Its Not Perfect. Ive used many example drawn from Apple products here, often as examples of bad interface practices. The Public Inspection page on FederalRegister.

Apple has made many revolutionary breakthroughs in interaction technology, a trend I fully expect will continue. They also make mistakes, fewer than most, but because I use Apple products almost exclusively, I suffer from them daily. While composing this document on my various Apple devices, its only natural that I extract examples from what I see here and now. Please do not take from this document that I am somehow an Apple hater. Leave-Encashment-KPK.jpg' alt='Revised Leave Rules 1980 Pdf' title='Revised Leave Rules 1980 Pdf' />In 1. I designed Apples first human interface after being recruited by Steve Jobs. I spent more than 1. I buy most every new major product Apple releases on Day One and have much of my retirement invested in Apple stock. I love Apple, support Apple, but would like it to do even better. Aesthetics. Principle Aesthetic design should be left to those schooled and skilled in its application Graphicvisual designers. Principle Fashion should never trump usability. Generating artificial obsolescence through fashion is a time honored and effective way to sell everything from clothing to cars. A new fashion should not and need not detract from user performance Enormous visual and even behavioral changes can be carried out that either do not hurt productivity or markedly increase it. Principle User test the visual design as thoroughly as the behavioral design. User test after aesthetic changes have been made, benchmarking, where applicable, the new design against the old. Ensure that learnability, satisfaction, and productivity have been improved or at least have stayed the same. If not, newly added aesthetics that are causing a problem need to be rethought. Top Anticipation. Principle Bring to the user all the information and tools needed for each step of the process. Software and hardware systems should attempt to anticipate the users wants and needs. Do not expect users to leave the current screen to search for and collect necessary information. Information must be in place and necessary tools present and visible. Anticipation requires that designers have a deep understanding of both the task domain and the users in order to predict what will be needed. It also requires sufficient usability testing to ensure the goal has been met If a tool or source for information is there on the screen, but users cant find it, it may as well not even be present. The penalty for failing to anticipate is often swift and permanent, particularly if you do not have a captive user, as is the case with public websites and apps, for example. Those users will probably never return from their search. Even if you do have a captive user, you probably dont have a captive client, and if the clients employees are wasting time trying to find required resources, your competitors will have a good story to tell when it is time to make their next pitch. Top Autonomy. Principle The computer, interface, and task environment all belong to the user, but user autonomy doesnt mean we abandon rules. Give users some breathing room. Users learn quickly and gain a fast sense of mastery when they are placed in charge. Paradoxically, however, people do not feel free in the absence of all boundaries Yallum, 1. A little child will cry equally when confined in too small a space or left to wander in a large and empty warehouse. Adults, too, feel most comfortable in an environment that is neither confining nor infinite, an environment explorable, but not hazardous. Principle Enable users to make their own decisions, even ones aesthetically poor or behaviorally less efficient Autonomy means users get to decide what keyboard they want to use, how they want their desktops to look even if they like clutter, and what kind of apps they want to run. When developers take that kind of control away, users can be left frustrated and angry. Principle Exercise responsible control. Allowing users latitude does not mean developers should abandon all control. On the contrary, developers must exercise necessary control. Users should not be given so much rope they hang themselves. However, some developers today are not only taking excessive control, but making huge HCI errors in the process, like restricting text to fonts and sizes that people with ordinary eyesight cant read. They offer editing schemes that require the user to use their fat finger to place the text cursor with pixel precision accuracy just to avoid adding the necessary arrow keys to their aesthetically perfect, but functionally crippled, keyboard. Manual De Instrucciones Psp Sony. They also set an arbitrary timing and movement threshold for determining whether a user is or is not pressing a link on purpose, rather than her just pausing for an instant at the start of an upward swipe for scroll, for example. They then offer the user no way to alter that threshold, so many users find themselves triggering links to unwanted pages many, many times per day. That is an irresponsible application of control. We learned 3. 0 years ago that users needed access to a slider for mouse double clicking. Touch users need the same thing for link timing. Perfect Link Triggering, Every Time.
