As interaction design is important to understand the background history because what we are made now is not just made. The ancient history of invention has been brought together to develop the current technology. Humans like to record everything and we learn from the information of records. Thus the invention of printing continued, and the invention of moveable type had a great influence on the development of human history by providing a turning point in the recording and dissemination of information. With the advent of new printing technology, knowledge enjoyed by only a few aristocrats in the Middle Ages could no longer be their exclusive property. Thus as an example of Leonardo da Vinci in the Renaissance period, he influenced many people as a starting point for the development of invention in terms of technology. As an interaction designer, I think it is important to know historical knowledge by thinking about the technology used by humans, and by playing the role of finding and researching security points.
