Then he said “as designers we put things between people and the world.” As a designer, you should use touch, smell, hearing and other methods to perceive the world. Use the “dichotomy” to investigate and understand user ideas and user needs. At the same time, he also cited many examples to emphasize the importance of the medium, just as in a party invitation, using cartoons or sketches can add to his interest. In the design, we are more concerned with the deeper things inside the design, to understand its working principle, so that we can effectively solve the problem when an error occurs. The user interface in the design is an important part of the interaction between the machine and the human. Therefore, every handle in the machine and every button or arrow in the interface has to go through a continuous test system to achieve “human-computer interaction”. Of course, you also need to be always aware that wanting is the goal of thinking. As an image designer, you must use “visual thinking” to process symbols and draw diagrams. Use the Internet to do more visual design.
