CSCI220 Multimedia Literacy

Course Introduction

Terms and Technology

multimedia what is it
Multimedia – what is it?
  • Give examples…
  • http://www.saint-andrews.co.uk
  • http://www.balloonmanor.com
  • 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
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!”

slide4
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
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
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

slide7
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
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
Concepts

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
Media Types:
  • Text
  • Graphics/images
  • Animation
  • Sound
  • Video
slide11
Text

- 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
Text
  • 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
Text
  • 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
Text characteristics
  • Size measured in points
  • Serif – with feet or tails

ABCabc

  • Sans serif

ABCabc

slide15
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

More Word Art...

This is Word Art!

And more word art...

slide17
Graphics/Images

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

Many storage/file types:

bmp, gif, jpg, tiff, others?

slide19
Animation
  • 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
Sound/Audio
  • Waveform audio – digitized recording

- describes frequency, amplitude, etc

- “samples” sound thousands of time per second

slide22
Sound/Audio
  • 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
Video

photographic animation

  • Live Video Feed – www.cnn.com
  • Videotape – play from MM app
  • Videodisc – laserdisc, DVD
  • Digital Video – digitized

- stored on computer media

- transmit over network (Web)
