There is history, concepts, examples, and some related theories of affordances. It is important that affordability can be effectively used in design. Affordability can connect things, users don’t need too many actions, they just need to see to know what to do. Interaction design also adopts this concept. At the same time, it is described as the basic design principle in textbooks. Elements of the user interface, such as clickable buttons and slipping parts, provide powerful clues to the user.
Examples of appropriate users of directly displaying interfaces:
- Clickable button and hyperlinks
- Drag gable sliders
- Clickable tabs
- A swappable touchscreen slider
- “pressable” buttons and “spinnable” controls of a touchscreen widget.
When the general idea of affordances was introduced to design by Norman (1988), using some strong brush strokes. The introduction was convincing, but it had not many details. He himself admits that it’s not accurate. According to the essay of communication design and HCI, designers should combine this concept with research and practice.
