Interactive design is a goal-oriented design, and all the work content is designed around user behavior. By designing users' behaviors, interaction designers can make users realize product business goals more conveniently and efficiently, and get a pleasant user experience.

Two. The position and task of interactive design in the project process;

Processes and nodes in the early stage of the project:

The refinement of functions is to make products achieve the ultimate in every professional link and improve their competitiveness. If we follow the process, every link is task-based delivery, and the bloated division of labor has no practical significance except increasing costs and slowing down the progress of the project. So interaction design needs to be done well enough to make this work meaningful.

Ⅲ. Specific functions of interaction design:

As can be seen from the above figure, interaction design mainly does three things:

(1) clear some requirements; ② Define information architecture and business process; ③ Organize the page elements and make a prototype demonstration.

(1) Define some requirements.

In the past, the inertia thinking was that product personnel were responsible for the requirements, and designers only realized and improved the interface experience. The real demand of products not only comes from business, but also includes the emotional needs of users. In terms of emotional analysis, the interactive major has advantages, such as:

A value-added service promotion module, the business model may be like this:

After considering the emotional factors, the demand model will continue to improve:

The picture above is just an example. Real product people don't think the business model is so simple. This example is to show that product requirement design is not only a business model, but also needs to consider user emotion, user behavior and operational data. When the product personnel are not considerate, the interaction designer has the responsibility to modify and improve the requirements to make the goal-oriented design complete.

② Define the framework

This part belongs to the core work of interaction designers, which is the framework design stage I mentioned in the last chapter. The output quality at this stage directly affects the business objectives and conversion rate. The framework is chaotic, and how to optimize the next interface is invalid. It's like the aisle design of a large supermarket. If the route planning is not good, no matter how big the guide icon is, it is inefficient. What does interaction design do? It is the significance of framework design to let users accomplish their goals quickly and improve operational efficiency.

Introduction to Polo's article: This chapter mainly introduces the function of interaction design in detail-what does interaction designer do specifically?

What is frame design? This is divided into two parts:

1. On the Design of Structural Navigation

Think of our product as a huge library. We need to help users (purposeful, ambiguous and aimless) find books they are interested in, and how to help users find and complete their goals and tasks accurately. This is the navigation design. Navigation design tasks are generally in new projects or reconstruction projects.

Navigation can be roughly divided into three types: structural navigation, associative navigation and usability navigation.

In the framework design stage, interaction designers mainly focus on the design of structural navigation.

There are two kinds of structured navigation: global navigation and local navigation. Global navigation generally refers to the first-level classification of irrelevant information structures, which is convenient for users to know what the whole website has in the fastest way. Local navigation focuses on the most convenient shortcut operation and business guidance operation for users.

The primary task of interaction designers is to organize and classify business content information, divide primary and secondary relationships, and define and plan the design of global navigation and local navigation according to business purposes and user habits. So how should we plan?

Back to the example of the first value-added service page (virtual case, unreal case):

After sorting out the requirements (how to sort them, please Google drawer sorting method), we can confirm the global navigation:

Then plan the local navigation in detail:

The hierarchy of local navigation can be continuously extended downward, and users will not get lost when browsing tree directories or breadcrumbs.

2. About process design

In the previous case, we have basically determined which pages the module needs and what content the page may contain. But the real user task can't be completed in one page. At this time, it is necessary to clarify the task through the process and curb all kinds of misoperation of users.

Virtual case:

In the process planning and design, we should follow: 1. Mainly oriented to commercial purposes; 2. Compatible with user habits; 3. Try to subtract processes, and one more process will lose some users; 4. The tasks are coherent and clear; 5. Consider the complexity of implementation; Welcome to add …

③ Organize the page elements and make a prototype demonstration.

After the improvement of requirements and the design of the framework, the previous work still stays in the stage of abstract ideas. How to communicate ideas to others on the project team? Interaction also needs to express ideas and plans, so the best way is to make a prototype Demo. Do Demo, let product, development and testing see the prototype of the product intuitively, then accept opinions widely, constantly modify and improve the prototype, do simple user tests, and continue to tap emotional needs.
