From my perspective, it is important for the interaction designer to have a basic background understanding of movable type printing. This helps give them ideas for icon and font design. And it is essential for the interaction designer to know the basics and some common practices. When doing this, one must learn to write characters in reverse with a Chinese brush. If interaction designers understand and learn this, they will have a new understanding of some fonts. It helps them with their design. Moreover, an understanding of movable type is very helpful for interaction designers when designing pages and typography. In movable type printing, the worker needs to know how each word is placed and what is the space between them. By understanding and learning this, interaction designers will be more efficient at designing pages. The designed page will also be more coordinated.
It is also important for the interaction designer to have a basic background understanding of the Renaissance as a time of invention, such as the invention of Leonardo da Vinci. His inventions were far ahead of their time, and some of them can even be used as a reference today. These inventions will bring a lot of inspiration to interaction designers.
