Interactivity design involves examining two entities and then creating a way for those two to work with one another. In case of interactivity between information forms such as multimedia elements, this becomes the force that binds the whole program together. After determining what kind of interactivity is appropriate for each application, the interactivity designer decides the points at which interactions between the user and the computer and user and the content take place. The mode of such interaction determines the engine development process of the application module. The way one module plugs into another without disturbing the harmony of the whole program is engineered.

How a user would navigate through various contents is decided through a complex process that involves psychological analysis and studies of various browsing patterns on pre-existing systems. Simplification of the choices and offering intelligently pre-determined paths ensure that the end user "travels" through the content in a logical and unconfusingmanner. Several models exist for organising the navigation layout - Linear, Hierarchical, Web, Parallel, Matrix, Overlays and Spacially zoomable models may be used within any application.
