For medium-user optimization now let me control the development of medium-size clock curves and software in software. The programmer is an expert in their own software, because they must explore each possible USE case, whether it is mixed or unlikely, write code to process. They naturally tend to design software as a model, in interaction, in interaction, the same emphasis on each possible option, they are unpublished as an expert. At the same time, sales, market and management personnel, they can't be expert users, or even secondary users, for customers, reporters, partners, investors to demonstrate products, those people themselves know less. Because they always come into advice, they will have a serious deviation for the insights of the user. As a result, it is not surprisingly, sales and marketers become an advocacy of the interface to serve the newbie. They asked to help the product attached to the product to help struggle newcomers. The interaction creation of programmers is only suitable for experts, while the interaction of market staff is only suitable for newers, however, as we have seen, the largest, most stable and most important user group is, medium users. Most of the most exclusive users are really surprised, but it is often the fact. You can find this in many business and commercial software products. The overall design allows products to tend to be expert-level users, while the annoying tools like the elves or papermakers are tied to the product to meet the feelings of the market department for new users. Experts rarely use these tools, and novices will soon think of this is always embarrassed to remind their ignorance. But most of the permanent secondary users are always sticky by these things.
Axiom is moderately optimized
Our goals are neither seduce novice nor to let the medium users become an expert. Our goal is to combine three: so that novice is fast and no pain, becoming a secondary user; don't give it to the middle user of experts, and the most important thing is that the permanent in maintaining medium skills Secondary users, let them stay happiness. We need to spend more time to make the program for permanent medium user tube and easy to use. Of course, we should also be adapted for newcomers and experts, but it is not the expense of most users. Some basic strategies to do this in this chapter
Novice needs noble sensitive, it is easy to be frustrated during the first time, but we must understand that the state of the newbie stage is never purpose. No one wants to have always been a newbie. This is just that everyone has to experience through the ceremony. Good software shortens this process and makes people adopt. As an interactive designer, it is best to imagine users, especially newbies, is very smart and very busy. They need some guidance, but not a lot, and this process should be fast and purposeful. If the ski teacher starts his teaching from meteorology and alpine ecology, he will lose his student from him, no matter how super-skiing. Users need to learn how to operate a program does not mean that he needs or wants to understand how it works.
The axiom makes users think that it is very smart but very busy.
On the other hand, smart people are always better learning after understanding causality, so you have to give them a understanding of software. We use a psychological model to solve this contradiction. If the interface's performance model is close to the user's psychological model (as described in Chapter Chapter 2), you can provide them with the needs of the needs of the user without having to understand the implementation model.
Let the newcomer to get a new user must be able to grasp the concept and content of the program immediately, otherwise he will give up it. Therefore, the first equation of the designer is to ensure that the software fully reflects the user's psychological model for the task. If the concept of the interface is adapted to his psychological model, he will not find out which command is to operate a special object, which will clearly remember the relationship between objects and operations, which is the most important concept. . Novice is an additional help for the second level that requires the process, but once they become a medium user, they will block their roads. That is to say, no matter what additional help you have, it should not be bound to the interface. It must be aware that when it doesn't require its service. The wizard tool displayed in dialog box is a good means of conveying the total, content and purpose. When the user starts the program, the dialog box can display the basic goals and tools of the program and name it for the main characteristics. The wizard is only concerned about novice problems, such as content and goals, and avoiding medium users and experts (described later), it is enough to help newers. Novice is very dependent on the menu to learn and execute the command (you can see why this is described in Chapter 27). The menu may be slow and cumbersome, but it is also thoroughly detailed, people who are relieved. If the menu item pops up the dialog, they should make a concise instructions yourself and have a convenient undo button. Experts need any expert-level users are also a very critical group, because relative to their fewer numbers, there is a powerful influence for more than experienced users. When a potential buyer considers your product, he is more willing to trust an expert opinion rather than a medium user. If an expert says "it is not very good", she doesn't matter "it is not very good for experts." But novice does not know this, he will accept expert advice, even if it is not suitable for him. Experts may occasionally look forward to the essence of the Olympic, and it is very dependent on these functions. They will make a clear requirement to provide quick access to their common tools, and often a few quantities. In other words, experts want each matter to have shortcuts. Anyone will quickly master the subtleness of the interface throughout the day. They don't want to make a full-purpose order, but this is inevitable. For frequent use, remember is just right. Expert users always aggressive seek more and learn more about their operations and procedures behavior and performance. Experts appreciate new powerful features. Since they have the mastery of the program, they have made them immune due to increased complexity.
Permanent secondary users need any permanent medium need to use tools. They don't need to explain to content and use because they already know. Tool Tips (see Chapter 29) is an ideal use for permanent medium users. Tool Tips do not say to content use and meaning, it is just a summary of the function, while only occupying very little visual space. Permanent medium users know how to use the reference material. They also have a motivation to study, as long as they don't think too much. This shows that online help is a permanent medium user tool. They use the index mode to use help, and this part of the help must be very comprehensive. Permanent medium users will divide the functions into their periodic useful and rarely used. They may try the essence of the Olympics, but will soon recognize (which may be unconscious) his common work sets. Users will ask them to be used in front and middle of the user interface to facilitate finding and remember. Permanent medium users generally know the existence of advanced features, even if they may not need these features, if they are used. But knowing that they will make permanent secondary users, so that he feels that investment in the program is the correct choice. Ordinary skiers will feel relieved, if you know the expert track of the realist's black-tarant mark behind the bus, even if she never intends to use it. Its existence gives her look and dreams.
Figure 3-1: The user needs to rely on their experiences for the software. Tools that provide users need to reflect this gap. Your program does not help but make it convenient for the first time to discriminate its quality, because most users will become a permanent medium. Similarly, if there is only a professional full-time expert to use the product, then the interface needs to cater to their special needs. Your program code must level support amateur users and experts may encounter all the situation. Don't let this technology require your design ideas. Indeed, you must provide these features for expert users. Indeed, you must support your novice. But you must put your talent, time and resources into your design as possible to serve your most typical users: permanent secondary users.
