CSCI220 Multimedia Literacy

Course Introduction

Terms and Technology

Multimedia what is it l.jpg
Multimedia – what is it?

  • Give examples…



  • Where have you experienced multimedia?

  • Use of a computer to present and combine text, graphics, audio and video with links and tools to let the user navigate, interact, create and communicate

Slide3 l.jpg

  • multiple media sources – involve more senses

  • Retention rate:

    • 20% of what they see (kinesthetic)

    • 30% of what they hear (auditory)

    • 50% of what they see AND hear

    • 80% of what they see, hear and do simultaneously

      “Tell me and I will forget;

      show me and I may remember;

      involved me and I will understand!”

  • Interactive Media:

    Allows user to respond directly to and control any of the media aspects

    • involve the user

    • Supply depth of use and display of information

    • Gives user choices, freedom

Slide5 l.jpg

Two types of media

Linear Media

- progress through set sequence of events

- presentational, slide deck

- no choices of direction

- can direct or focus attention to specific details

Slide6 l.jpg

Two types of media

Non-linear Media

- order of events dependant on user

- “choose your own ending”

- freedom to move and learn at own pace

- more presentational flexibility

History of Multimedia

Multimedia (w/o computers) not new

  • Text with photos/graphics (newspaper/mag)

  • Sound with animation (tv, movies, games)

  • Introduction of smell (scratch and sniff stickers and movies)

  • “Interactive” text – choose your own ending books

Slide8 l.jpg

History of Multimedia

Multimedia Growth:

  • Better computers – faster, more storage

  • Better software – easier to use

  • More MM uses discovered

  • Web spurred growth

  • Computer-based MM new (within last 10 years)

Slide9 l.jpg


Digitized – media elements captured as a series of 1’s and 0’s so computers can work with the media

Focus - direct user’s attention to one concept

Balance – between information (content) and media aspects

Slide10 l.jpg

Media Types:

  • Text

  • Graphics/images

  • Animation

  • Sound

  • Video

Slide11 l.jpg


- used as headlines, subtitles, captions

- provide content and direct information

- give directions, navigation

  • Printed text – on paper

  • Scanned text – hand held or flatbed scanner - digitizes page of text into graphic

    - OCR Optical Character Recognition

Slide12 l.jpg


  • Electronic text – in electronic form only

    • E-zines, online newspapers, web content

    • MS Reader

  • Hyper text

    • Allows non-linear access to information

    • Link to related information

    • Like cross reference

    • Used in WWW, CD Rom, reference material

Slide13 l.jpg


  • Font – style of text

    • Screen/Printer font – may appear different on other printers/screens

    • TrueType font – device independent

    • Bitmap converted text – make text headings a graphic to preserve exact look of font

Slide14 l.jpg

Text characteristics

  • Size measured in points

  • Serif – with feet or tails


  • Sans serif


Slide15 l.jpg

Text characteristics

  • Kearning – amount of space between characters: abc a b c a b c

  • Leading – amount of space between lines of text

  • Word Art – font special effects

  • Bold, Italics, Underline, Alignment

Slide16 l.jpg

More Word Art...

This is Word Art!

And more word art...

Slide17 l.jpg


Two major types

  • Graphic Image/Illustration

    • 2D and 3D

    • “hand drawn” or computer generated

    • Charts and graphs

  • Photographic Image – digitized

    • Digital camera/video

    • scanner

Slide18 l.jpg

Many storage/file types:

bmp, gif, jpg, tiff, others?

Slide19 l.jpg


  • graphic images that move

  • Convey information better than static graphic

    • i.e. sign language demonstration

  • Motion grabs user attention

  • Play to user’s visual acuity

Slide21 l.jpg


  • Waveform audio – digitized recording

    - describes frequency, amplitude, etc

    - “samples” sound thousands of time per second

Slide22 l.jpg


  • CD audio

    - play sound directly from CD

    - CD ROMs fast enough to jump to any point in 75th of a second

    - games use it for background and theme music

  • MIDI – Musical Instrument Digital Interface

    - recording and storing musical performances

    - specific commands for volume, tempo, timbre, etc.

Slide23 l.jpg


photographic animation

  • Live Video Feed –

  • Videotape – play from MM app

  • Videodisc – laserdisc, DVD

  • Digital Video – digitized
