Sometimes the product of visual communication must not only include a consistent dose of pragmatism, but, in order to be truly effective, it should NOT be noticed. In fact, it should be a natural extension of what the product expresses.
This is the case, for example, of GUI (Graphic User Interface) projects and of
UX Design in general.
By GUI, we mean the design of the graphic interface of a machine, which ensures that the interaction between the human operating the machine and the machine itself can happen in a visual and -to a certain extent- natural way.
What you see (the graphic interface) is only the tip of the iceberg of a huge submarine mountain. The submerged part of the iceberg represents all the complexity that the GUI and the Human-Machine Interface (HMI) have to translate in a user-friendly way, in order to be effective.
