critical reflection of  MIDEA journey

I come here with product design skills and IoT product manager experience, aiming to enhance my capabilities from user needs discovery and product visual effects to full-stack abilities.
In this MIDEA journey, the three Key practical skills I learned are Figma, p5js, and Rhino. Figma enables me to quickly describe various two-dimensional ideas in projects, p5js opened my understanding of programming languages, and Rhino allows me to create various three-dimensional product forms. Each skill has freed my creativity and concepts from constraints, bringing more possibilities for future career development.
Among Key theoretical concepts, the double diamond design thinking model has run through my interaction design learning journey, helping me better understand various design tool kits of design thinking. The two design books "Design for How People Think" and "Designing Interfaces" enhanced my design cognition from the perspective of brain science and cognitive psychology. For example, in the Olympic Games navigation system UI design in 9105, I stacked many icons in the interface, and too many interfering elements affected user attention. Understanding the structure of human brain cognition reduced the occurrence of those seemingly reasonable but counter-intuitive designs.
During this journey, I became familiar with various required skills and concepts, but there is still a lack of practical verification of theories, such as: Is the user testing plan for discovering problems rather than avoiding them? Were conclusions preset during research? These are questions that need to be asked forever in future design careers, but I'm glad I realized the existence of these problems.
Today, I have gained more rigorous design thinking, learned how to conduct more professional user research methods, and understand how to create products that better meet user needs. I will bring these skills to create digital experiences that will change the future.
