What do non-interactive multimedia means?

Answer 1

They mean pictures, audio and video which doesn't interacts with the user.

A better answer can be ...

Linear (Non Interactive)active content progresses without any navigational control for the viewer such as a cinema presentation. Non-interactive form of multimedia in which a project starts at a beginning and runs through to the end. Conventional "television" is essentially "linear multimedia" (although switching channels could be said to involve interactivity). However, there is no ability for the end user to control when elements are to be delivered. Some multimedia projects are like television in that they present material in a linear fashion from beginning to end.

Linear multimedia can be distinguished from non-linear multimedia because it has literally no interactivity of any kind. It lacks any extra features that a user can take advantage of, such as the ability to choose different options, click on icons, control the flow of the media, or change the pace at which the media is displayed.

The main reason to use linear multimedia over the more interactive and fun non-linear types of multimedia is to aid in teaching or training. Linear multimedia works exceedingly well for providing information to large groups of people such as at training sessions, seminars, workplace meetings, or study groups.
