Direct Manipulation Interfaces
Interfaces that speak in the languages of what you are interacting with (i.e. files, photos). They do not require much prior knowledge, expecting the user to recognize rather than recall the interface. They also support rapid and risk-free exploration. Actions within a direct manipulation interface usually has immediate feedback. In lecture, Finder (file browser) and iPhoto (photo app) were good examples of direct manipulation interfaces, while the Terminal was not considered one.
Drag-and-drop website builders such as Weebly are good examples of direct manipulation interfaces, as you interact with layout, pictures, and text rather than HTML and CSS code.
