Types of Multimedia Content

Multimedia content may be broadly divided into categories: Linear Multimedia and Non-Linear or Interactive Multimedia.

1. Linear Multimedia ( Non-interactive )

In linear interactivity, the user interacts with the multimedia application without controlling the progress of the content. In other words, the user is a passive receiver of the multimedia content most of the time. The linear content is usually arranged in sequence. An example of multimedia linear content is a movie. Although a movie uses a combination of audio, graphics, and animations, the user has no control over the sequence of events.

2. Non-Linear or ( Interactive) Multimedia

Multimedia applications that allow users to actively participate instead of just sitting by as passive recipients of the information are called Interactive Multimedia. In other words, it is two-way communication. It allows the user to interact with the content according to what the user wants from the content. The user can control the progress and sequence of the multimedia content by using buttons or links. Hypermedia is an example of non-linear content.
