Before we can understand visibility, we need to understand the signifier of a new word. It first appeared in Donald Norman's Design Psychology. In the book, Norman defined it as the relationship between a physical phenomenon and people. That is, the relationship between the characteristics of the article and the theme that determines the intended use of the article.

In short, how tangible things convey important information about people who interact with them. It not only refers to the material and technology of the object itself, but also includes the purpose and usage of the product. Every object has an appearance, and we can quickly understand the appearance of many things through our own life experiences. However, due to the increasing complexity of products, the performance of many products needs designers to express more clearly through some means, which is the shaping of product visibility.

The effective means to realize visibility in design is signifier, that is, the position of operation is indicated by some symbols and shapes. In design, signifier is more important than design, because it plays the role of communication and tells users how to use this design. The design of signifier processing mode is the display of designer's ability. The better the signifier is designed, the more energy and thinking the designer needs to devote.

For example, it is also to prevent people from not knowing how to use the glass door when opening and closing it, and some simply push or pull it on the door rudely, but good designers have considered this problem from the beginning when designing the door and integrated their own thinking into the design. For example, the following hidden door has been well integrated with the wall, but the design of several grooves clearly tells the user that the way to open and close the door from that direction may be push and pull.

The above is about the sharing of design visibility. Design is not something that can be found in a flash of light, nor is it a simple appearance design, but it is a combination of designers' thinking and research on products and people's lives. Design is rational, design is not an artist!
