What things do interaction designers need? Some people don't understand the recruitment of the network. What are the so-called related majors? . .

interaction design is a dialogue between designers and things, and the essence of interaction design research and practice may be hidden in this dialogue. The purpose of interactive design includes the design and improvement of usefulness, ease of use and attraction.

Especially in the digital age, multimedia makes the research of interaction design more diversified, and the analysis of multi-disciplines and angles makes the theory of interaction design more abundant. Nowadays, more and more products based on interaction design have been put into the market, and many new products have absorbed the theory of interaction design in large quantities.

fields where interaction design can be applied

interaction designers usually work in the following fields: software interface design, information system design, network design, product design, environmental design, service design and comprehensive system design. Each of the above-mentioned fields needs its own design characteristics, and at the same time, it will also use the general principles and practices of interactive design.

general steps of interaction design

generally speaking, interaction designers follow similar steps to design and provide a solution to a specific design problem (note that there is no absolutely correct solution). The key to the design process is rapid iteration, in other words, rapid prototyping is established and the design scheme is improved through user testing.

The following are the main points of interaction design steps:

User research: Through the means of user research (intervention observation, non-intervention observation, interview, etc.), interaction designers investigate and understand users and their related usage scenarios, so as to have a deep understanding of them (mainly including users' psychological patterns and behavior patterns), thus providing a good foundation for subsequent design.

Conceptual design: By comprehensively considering the results of user research, technical feasibility and business opportunities, interaction designers create concepts for the design goals (the goals may be new software, products, services or systems). The whole process may be iterated back and forth for many times, and each process may include activities such as brainstorming, conversation (unreserved conversation), and refining the conceptual model.

creating user model: based on the user behavior patterns obtained from user research, designers create scenes or user stories or storyboard to describe the possible future forms of products in design. Usually, designers design persona as the basis for creating scenes.

Creating interface flow: Usually, interaction designers use wireframe to describe the functions and behaviors of design objects. In wireframe, the details of the system are described by paging or split screen (with notes of relevant parts). Interface flow chart is mainly used to describe the operation flow of the system.

prototype development and user testing: interaction designers test design schemes by designing prototypes. Prototypes can be roughly divided into three categories: functional testing prototype, sensory testing prototype and realization testing prototype; In a word, these prototypes are used to test the quality of interaction between users and design systems. The prototype can be physical or computer simulated; It can be highly simulated or roughly similar.
