What is an Example of Projected and Non-Projected Media?
An example of projected media is a film projector, while an example of non-projected media is a printed chart. These two categories of media differ fundamentally in their requirement for a light source to display content.
Understanding Projected Media
Projected media refers to any medium that necessitates a light source to cast an image onto a surface, such as a screen or wall, for viewing. Without this external light source and a projection device, the content cannot be effectively displayed or observed by an audience. This characteristic makes them dynamic and often suitable for group viewing in controlled environments.- Key Characteristic: Requires an external light source for display.
- Purpose: To enlarge and display images or moving pictures for an audience.
- Common Applications: Educational presentations, entertainment (movies), public displays.
Understanding Non-Projected Media
In contrast, non-projected media includes any material that does not require a light source or a projection device to be viewed. These media are often tangible and can be interacted with directly without the need for specialized equipment for display. They are typically static and can be used in a variety of settings, often for individual or small-group use.- Key Characteristic: Does not require an external light source for display.
- Purpose: To present information directly through physical objects or printed materials.
- Common Applications: Self-study, hands-on learning, reference materials, exhibitions.
Examples of Projected and Non-Projected Media
To illustrate the difference more clearly, here is a breakdown of common examples for both types:| Media Type | Description | Examples |
|---|---|---|
| Projected Media | Requires a light source and a projector to display content. | Film projector, slides, overhead transparencies, digital projectors. |
| Non-Projected Media | Does not require a light source or projector for direct viewing. | 3-dimensional objects (e.g., models, realia), 2-dimensional objects (e.g., photographs, diagrams), prints, charts, models, textbooks, maps, blackboards. |
Understanding the distinction between projected and non-projected media is crucial in selecting the most appropriate tools for various educational, informational, or entertainment purposes, based on the required display method and the viewing environment.
