In the book “Things That Make Us Smart” by Norman, it gives an exploring the relationship of technology and humans. It is interesting to know a lot of information about how to determine whether an artifact is effective, and how to make a tool a more effective cognitive artifact. The representation has got my attention, which external representations can assist our brains to get deeper psychological understanding. This new visually has much power in the real than I thought before. The representation shows the relationship between objects and processes at a high level of abstraction, which is suitable for getting an overview of actual function process. Such as cartoon videos, and more cartoon movies have more production. Many impressive films are also comic books in recent years, such as “Transformer”, “Iron man”. I believe it’s a very powerful representation to provide virtual reality, which it was a new fusion between real and virtual worlds. In the current industry, mostly we have the prototype first, then we build a model, and finally we have the actual product. Representation gives us more possibilities, to bring our image into reality.
