What's New in Macintosh Human Interface From Apple xxii. About Making It Macintosh xxii. What's in This Book xxii. The Basic Philosophy xxii. The Interface . In iOS Human Interface Guidelines, the word screen is used as it's for printing images and PDF content, or you can use printing-specific. This part of Apple Human Interface Guidelines presents the that can be sent to a printer, faxed, or saved as a PDF file (Figure ).
Unlike today where both consumers and engineers appear to be itching for all of the automation and self-operating machines they can get, those who were dealing with computers early on foresaw their vast potential and were extremely wary of relinquishing any control to them. Too often, however, the computer acts and the user merely reacts within a limited set of options.
We are much more user-focused. However, this simple statement leads me to believe that they were very well-grounded in the human experience.
For them, the computer was a extraordinary tool with the dangerous potential of becoming more than that. People strive to master their environment: they like to have a sense of control over what they are doing, to see and understand the results of their own actions. You may have read later versions of the Apple Human Interface Guidelines and be thinking that they cover pretty much the same stuff, and you would be right.
These early pioneers knew their craft and their ideas continue to be relevant. In my opinion, the wording and explanations feel more clear and, in some cases, more correct than the current Apple Human Interface Guidelines , so I feel like some of the richness of the original guidelines has been lost in the successive revisions. When they are clear and consistent, they contribute greatly to ease of learning, communication, and understanding.
This would detract from the clean elegance Apple now prefers over clear understanding and usability. Out went undo. So guess what happened? People complained. En masse. So they put undo back in, sort of: All you have to do to undo is to violently shake your phone or tablet. But undo is not universally implemented, and there is no way to know except by shaking. Touch-sensitive screens, especially on relatively small devices, offer multiple opportunities for things to go wrong when an active link or button is accidentally touched.
These accidental touches move the user to a new destination.
The standard, simple way of correcting for these occasional mis-touches is to have a Back control: Android phones have Back built into the phone as a universal control that is always available. Apple does not. Were they trying to avoid having a button or a menu? The result does provide for a clean, elegant visual appearance, but the simple-appearance mask is deceptive, for it increases the difficulty of usage.
Not everyone, including Apple, implements these features. The product is beautiful! And fun. As a result, when people have difficulties, they blame themselves. Good for Apple. Bad for the customer. Someone should write a book about this. Oh, wait, both of us have— several books. Good design should be attractive, pleasurable, and wonderful to use.
But the wonderfulness of use requires that the device be understandable and forgiving. It must follow the basic psychological principles that give rise to a feeling of understanding, of control, of pleasure.
These are all principles we teach elementary students of interaction design. If Apple were taking the class, it would fail. As a result, programmers rush to code without understanding the people who will use the products. Designers focus entirely on making it all look pretty.
And executives get rid of user experience teams who want to help design the products properly and ensure the products are made usable during the design phase, not after manufacturing, coding, and release, when it is too late. These uninformed company executives assume all this up-front design research, prototyping, and testing clearly must slow down the development process.
When done properly, it speeds things up by catching problems early, before coding even begins. Apple products deliberately hide complexity by obscuring or removing important controls. The result of avoiding proper design methodology?
Higher costs for service lines, for help. Just how much of the new technology have they mastered? Yes, gesture-controlled devices, tablets, and phones have easier barriers to initial use.
But they have huge barriers to anything advanced, such as selecting three photos to send in an email, or formatting some text, or combining the results of several different operations.
These and myriad other operations are far easier and more efficient on traditional computers. More Attractive And More Difficult To Use The new generation of software has made gigantic leaps forward in attractiveness and computational power while simultaneously getting harder for people to use.
The problem is not restricted to Apple. Google maps become more attractive and more confusing with each iteration. Same with the Android operating system. Microsoft has recognized the problem, and the introduction of Windows 10—skipping over 9—is meant to overcome these issues: We do not yet have enough experience with the product to form any opinion.
Advertisement Why the problem? Because design comes in many flavors, just as every discipline has multiple flavors.
In software, a driver programmer is not necessarily any good at interaction programming, nor is the kernel developer good at telecommunication programming. In the design arena, interaction designers trained in psychology know the principles of conceptual models, clarity, and understandability, while those trained in computer science may not, and those from the graphic design field seem to think that interaction design means websites, and they often fail to understand either programming niceties or human-computer interaction.
It matters that our leading products are going backward in both usability and usefulness. What Went Wrong? One of us, Tognazzini, worked at Apple with Steve Jobs in the early days. Norman joined Apple shortly after Jobs departed and then left shortly after Jobs returned in We do know that before Jobs returned, Apple had a three-pronged approach to product design: user experience, engineering, and marketing, with all three taking part in the design cycle from day one to when the product shipped.
Unfortunately, visually simple appearance does not result in ease of use, as the vast literature in academic journals on human-computer interaction and human factors demonstrates. Apple products deliberately hide complexity by obscuring or even removing important controls. As we often like to point out, the ultimate in simplicity is a one-button controller: very simple, but because it has only a single button, its power is very limited unless the system has modes.
