CT 201 Visual Media Projected and Non Projected

Visual media are of two types:

→Projected visual media

→Non-projected visual media.

We will mainly focus on projected media but you are supposed to read about non-projected visual media. We have covered some of the non- projected media when we were discussing traditional media.

Non-projected visual media

These are media which do not require an electrical outlet when displayed.
They include pictures, charts, graphs, posters, and cartoons which provide powerful visual support to abstract concepts.
They can translate abstract ideas into more realistic formats.
They allow instructions to move from verbal level to more concrete level.

Projected visual media

These are media formats in which still images are enlarged and displayed on a screen.

The projection of image is achieved in various ways:

→Passing strong light through a transparent film as in overhead projectors.
→Magnifying image through a series of lenses.

The image can then be cast onto a reflective surface.

New projection techniques include storing images electronically and projecting them in a PowerPoint. Digital storage mechanisms include CR-Room, DVDs, Scanner, Memory stick etc.
