Interactivity Of Multimedia

If you use the first multimedia application, the content progresses without you having to control the flow of the movie.  Your only control is to press the “play” and the “stop” buttons.

This interaction is called linear interactivity.

On the other hand, the second multimedia application allows you to decide which part you would like to view, or how much you want to know about the content. 

This interaction is named non-linear interactivity.


Interactivity refers to the way users interact with a multimedia application or program.
How does a user control the content of a multimedia application? The user can use input devices such as a keyboard, joystick, mouse and  touch screen to interact with the application through the computer.
The content of the application provided, determines the interactivity for the user. An example is film that does not allow the user to control the content.
Another example is a computer game. It allows the user to use the left and right arrow keys to control the movement of the game.


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 the 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.


Unlike linear interactivity, non-linear interactivity allows the user to interact with the content according to what the user wants from the content. In other words, it is a two-way communication.

The user can control the progress and sequence of the multimedia content by using buttons or links.
Non-linear interactivity uses tools like “hypertext” to connect a word or a phrase to another screen.
An electronic book with links to another screen is considered as having non-linear multimedia content.
Hypermedia is also used in non-linear interactivity.  This tool is similar to hypertext. However, it connects to different media elements such as audio and video.
