For example, students majoring in computer science often learn some knowledge about the front-end development of Android, or some system requirements analysis methods such as software engineering and UML can help interaction designers to analyze requirements and choose interaction methods. Psychology helps to understand users' psychology, do a good job in user research and improve user experience.
Books:
If you are still a college student, I suggest reading more books on interaction design. The key points are:
Breaking the cocoon into a butterfly (Netease interactive designers can understand well what interactive designers are and how to work);
About Face4 (a classic essential book of interaction design, equivalent to the function of Oxford dictionary hhh)
Simplicity first: four strategies of interaction design (introduce the technology and skills of interaction design, and have a detailed interpretation of ease of use)
Don't make me think (touch the stone into gold, mainly introduce web usability design, classic recommendation)
Selected readings of popular psychology books
Information architecture: beyond web design (super classic polar bear book, mainly explaining information architecture, it will be more abstruse and difficult to understand. It is recommended to read it at last or after having some work experience)
You can read in this order to better understand what interaction design is and how interaction designers work, and then learn some interaction design methodology and even details. Even if you don't understand it for the first time, you can have a comprehensive understanding of interaction design.
Tools:
The basic usage of tools is enough. Thinking and methodology are far more important than tools, but it is recommended to master them here.
Axure (prototype tool) can also be used to draw interactive flow charts at most.
The sketch (prototype /UI) is beautiful, but it can't reflect the architecture.
mind map
Blue lagoon (efficient product design collaboration platform)
Visio (Mind Map /UML) is powerful, and drawing mind maps is wasteful.
MindManager (Mind Map) OminiGraffle (Mind Map/Prototype) is widely used abroad.
These are commonly used mainstream tools. In principle, it is good to choose one of the prototype tool and the mind mapping tool (used to draw flowcharts) for your own use. For beginners, even drawing flowcharts and prototypes on paper with a pencil is a good way to learn. The prototype of the paper is ok, and more importantly, the analysis method and thinking.
Exercise:
The most important thing for college students to engage in interactive design is practice. It is a better choice to enter some Internet companies, especially large Internet companies with standardized design processes.
As for the entry threshold, one is your professional counterpart. For example, if you are a student majoring in industrial design or computer science, you have a better chance to get an internship. It doesn't matter if the major is wrong. It is also a good way to master the above books and tools, experience the good products made by interactive design, write some experience reports and send them out, and win an internship opportunity with these achievements.
