2. What are Projected Materials?
• Projected materials enable educators to convey
information to large numbers of people at the
same time. However, such materials have to be
prepared carefully and may need to be prepared
professionally.

3. In all cases, they require three things:
• the material
• the projector
• the screen

4. Document Camera
• Document cameras, also known as visual
presenters, visualisers (in the United Kingdom), digital
overheads, or docucams, are real-time image capture devices
for displaying an object to a large audience. Like an opaque
projector, a document camera is able to magnify and project
the images of actual, three-dimensional objects, as well as
transparencies.

7. Overhead Projector
• Overhead Projector
–Student use:
• Display work to the classmates
–Teacher use:
• Versatile and inexpensive
• Use of transparencies that are projected on
the wall

10. Slides
• Photographic slide or transparency, a positive
photograph used for projection
• Microscope slide, a thin glass sheet used to hold objects
for examination
• Slide (form), a slide-out mobile phone form factor
• Evacuation slide, an inflatable slide used to evacuate an
aircraft
• Slide rule, a simple analog calculator

11. • Jakarta Slide, defunct Content Management System
software
• Pistol slide, the upper half of a semi-automatic pistol,
containing the barrel, sights, and ejection port
• Slide edit, a video editing term for moving a video clip
around in a timeline
• Linear-motion bearing, a bearing designed to provide free
motion in one dimension

12. As a future teachers….
• You must know that when making a Powerpoint
Presentation, always used contrasting colors
• Example:
• When using dark-colored background, the text must be in
light colors

13. • The standard font size for a Powerpoint
Presentation is 32.
• The standard line per slide is 9.

14. Digital Images
• A digital image is a numeric representation
(normally binary) of a two-dimensional image.
Depending on whether the image resolution is fixed, it
may be of vector or raster type. By itself, the term "digital
image" usually refers to raster
images or bitmapped images.

15. Terminologies for Digital Images
• Raster images have a finite set of digital values, calledpicture
elements or pixels. The digital image contains a fixed number
of rows and columns of pixels.
• Pixels are the smallest individual element in an image,
holding quantized values that represent the brightness of a
given color at any specific point.

16. Pixelated Photos

18. Unpixelated vs. Pixilated

19. CD-ROM
• A CD-ROM is a pre-pressed optical compact
disc which contains data. The name is
an acronym which stands for "Compact Disc Read-
Only Memory". Computers can read CD-ROMs, but
cannot write on the CD-ROM's which are not
writable or erasable.

20. • The Yellow Book is the technical standard that
defines the format of CD-ROMs. One of a set
of color-bound books that contain
thetechnical specifications for all CD formats,
the Yellow Book, created
by Sony and Philips in 1988, was the first
extension of Compact Disc Digital Audio. It
adapted the format to hold any form of data.

23. Photo CD
• Photo CD is a system designed by Kodak for
digitizing and saving photos in a CD.

26. DVD CD
• DVD (sometimes explained as "digital video disc" or
"digital versatile disc"[5][6]) is a digital optical
disc storage format, invented and developed
by Philips, Sony, Toshiba, and Panasonic in 1995. DVDs
can be played in many types of players, including DVD
players. DVDs offer higher storage capacity than compact
discs while having the same dimensions.

29. Digital Camera
• A digital camera (or digicam) is a camera that
encodes digital images and videos digitally and stores
them for later reproduction.[1] Most cameras sold today
are digital,[2] and digital cameras are incorporated into
many devices ranging from PDAs and mobile
phones (calledcamera phones) to vehicles.
