China UCD application cluster (Q Cluster Number:40294602) conducted a discussion of the relationship between interface and interaction. Now I want to write down my opinion on interface and interaction and expect more participation from followers.
Search “What is Interface?’ through Google, you would see a lot of definitions. While my view is that interface has two levels of discourse, one of which is sensation, including sense of visual, smell, hearing, touch and the like, and the other is emotion, as is easier to understand.
The opinion I prefer is that the procedure of interface design consists of Structure Design, Visual Design and Interact Design, which are the subsets of interface (Interface is a port.).
After reading Thought Fish’s ponderation on interface, I still keep my view. Since he considers interface design is more like the page of visual design or the design users can see. Here is his composition chart.

It can be concluded from my opinion that the left side of interface design should be composed of structural layout, contents and visual designs. And the controversial lies on the comprehension to interface.
