Interactive design of compatible mental model and system model

The reference to the mental model and the system model means that the concepts of the three models presented in the design psychology need to be used. All along, the design work of friends, whether in the product prototype design or visual design are as far as possible to make the system model with the psychological model closer. Because for a product of its system model and http://www.aliyun.com/zixun/aggregation/8161.html "> User psychological model closer, the product user experience better, users learn faster." But a complex product to make users directly from the performance of understanding the system model is often very difficult, only in the process of using products gradually familiar with the structure and characteristics of products, so as to master the product system model.

Friendly navigation, you know.

Some of the Internet product structure is very simple, through navigation can form a close to the system model of the psychological model, a new user will not get lost. First look at the "where" navigation:

"Where" the column structure is relatively simple, usually users look at the navigation bar can know the entire site's column structure. That is to say, when the user first sees "where to go" home page, the psychological model of the column structure is almost identical with the system model.

When a complex structure of products first appeared in front of us, we can not see its structure, then the user will create a disorderly and messy psychological model of the product. We are not going to investigate when using, as long as we can find the target on the line, not deliberately to identify the road. Usually when we come next time we will benefit from the vague impression that we have formed for the first time, and we can find the target more quickly. Only the user did not form an orderly psychological model and to have not been to the place to feel a strange, users of this strange fear will hinder users to actively explore unused functions. Alipay because of its own load of business and function too much, even after a large number of optimized navigation still can not make users feel enough relaxed. Maybe Alipay will be more popular for the layout of the reference SNS.

The simple system structure can quickly let the user understand the product, gives the user the friendly experience, but cannot carry the complex product function. Complex structure can not bring users a good experience, as the saying goes, fish and bear's paw can not be both. And in the practical application some excellent products will use some special methods to resolve this contradiction unintentionally, that is, in the performance of the user to form a product system model of a mistake, this kind of error knowledge, although different from the system model, but does not affect user use, but also bring a better experience.

Case one, Tencent Weibo, its own system model is also very simple, but will give different users to form a different psychological model, and will not affect user use.

The function of "skin change" is the function of "setting" in the column. Here in the performance of it and the parent column side by side, will make some users think "skin" is an independent level of function. We can also, on the other hand, put the "skin-changing" one-level function into the setup, which makes it easier for users to set other parameters.

Case two, 12582 (Agriculture-ICT).

Agro-ICT products are very complex, on the home page has two places to do the compatibility of interactive design processing. One is in the "my 12582" there, will be in the different levels of the entrance of the column together, the name is "my" beginning, the user will be the first time that these items are tied to the relationship, forming an orderly and inconsistent with the system model of the psychological model. The other is the icon navigation, here will be the different grades of agricultural ICT products are divided into two categories appear to have the same effect.

From the above examples we can conclude that if we can design a compatible interaction, so that users in accordance with a simple structure to understand the product, without affecting the user's use, can ensure that the user's mental model and product system model when the difference between the best experience.

The wise letter of the letter to make the new user "Home" (the following paragraph only represents personal opinion)

Fly a PC client program 2010 version of a widespread concern, we all have a feeling, that is more like QQ. Online also appeared the title contains "QQ plagiarism" and other words of the article, there are netizens to fly a letter to have some views, and I just think that flying a right way. Imagine what you would say if someone asked you what the letter was? I believe that more than 90% people will take QQ as a reference: Fly a letter is similar to QQ with a chat software. QQ coverage can be seen as a whole network, almost every netizen has used QQ, and most netizens are familiar with QQ, and accustomed to the various operations of QQ.

When a letter has not been used to fly the user heard is similar to the QQ software, the mind will think of QQ appearance, such as: bar The main interface, one-on-one square Chat window. When the user to use a flying letter, to carry out a certain operation will be in accordance with the use of QQ way to use. such as: Add a friend's entrance in the main interface below, open personal data is clicked Avatar, etc., view group list is clicked Horizontal tab bar second, space entrance is in the avatar below the small icon of the first. QQ coverage is too high, so that we can believe that the development of a letter to the new users have the characteristics of using QQ, that is to say, they use the QQ model to match the fly, so assume that the interaction can be the same as QQ, the user first use the letter will know how to use a fly with QQ common functions. The new version of flying more and more like QQ also means to fly to new users experience more and more good, users do not need to face and learn a strange interaction, easy to use. Flying in 2010 after a few versions more and more like QQ, but also to bring new users more and more good experience. This shift is sensible.

Excellent products will make users easy to use, there is intimacy, intimacy comes from the designer to the greatest extent to the user's psychological model of consideration. The best experience is sometimes not a clever innovation, but simply to meet the user's habits or give users a refreshing and orderly structure. Interactive design is to connect the system and the user's inner bridge, seize the user's heart, can let the user echocardiography.
