NUI Key concepts

Scene graph: Tree data structure, consisting of a collection of nodes.

Window: Top level of the scene graph, used for displaying a tree of Layers and Views.

View: Primary object for interaction. Views are effectively nodes that receive input (such as touch events), and act as a container for drawable elements and other views. Views can display content such as Color shapes, images, text etc. An NUI application uses a hierarchy of view objects to position visible content.

Layer: Layers provide a mechanism for overlaying groups of views on top of each other.
