Excellent design to be a specialization-the definition of superior sex

If you've ever tried to find the right kind of definition, it's possible to see how different learners or UI (User-interface) professionals are in the definition of superiority, perhaps because of the different backgrounds of the non-essential, some of the definitions are important in the use of efficiency, and some of them non-essential to the user's mental level, There are also a number of places to focus on design processes and business values, each of which is different in terms of approach and perspective, but what does not change is that superiority is a design concept that is considered from the user's perspective.

As defined by the International Standard organization ISO (Analysys from for Standardization), the advantage is that it allows its users to perform certain tasks in an efficient and satisfying situation (usability is The "effectiveness,&http://www.aliyun.com/zixun/aggregation/37954.html" >nbsp;efficiency and
Satisfaction with abound a specified the set of users can achieve a specified set of tasks in a particular environnement. "), that is to say, An excellent product must enable the user to complete the work smoothly, and be satisfied with the whole process.

Jacob Nielsen has put forward five features for the advantages of Web site design:

Learning: Users can learn how to use them in a short period of time when they first face an unused interface, and do some basic work.

For example, when the user first comes to Amazon.com to find a book, his basic task is to find a book that fits his needs and complete the subscription, Amazon's function is not only to find books and shopping, but this is the most basic function, then the Web site design must enable the first visitors to the user in the shortest possible time to complete these basic work.

Efficiency: If the user is able to get a better understanding of the interface design of the website, it will be possible to finish the work more smoothly.

Memory: When users visit the site two degrees, can immediately recall the operation of the Web site.

A good design should not allow people who have been used to recall the use of the Web site, or even learn how to use it.

Error rate: What are the rates and severity of the errors that users will have when they operate? Whether or not the user can solve these mistakes on his own.

The interface of the website is the communication pipeline between the user and the System (website), and it is almost impossible for the user to make mistakes completely in the process. But a good design should allow for a reduction in the seriousness and incidence of errors, and when bugs are generated, users can understand the cause of the error and adjust the way it is used.

Contentment: After use, is the user satisfied with the whole process?

Whether the user is satisfied with the fact that it is very subjective and difficult to measure, the user will sometimes be judged by his personal preferences, a good interface design does not necessarily make the user feel particularly satisfied in the whole evaluation, in some cases, because the use of the process is too smooth, users will not have any special feelings, As Don Norman once said, "at some point, when your customer/user is no longer talking to you about the product usage problem, and you know that your design is right", however, if it turns out to be a problem, by a number of actual tests, We can make sure that the poor use of interface design will definitely change the degree of satisfaction.
