Multimedia

• A form of communication
• Multimedia Applications that use multiple
  modalities to their advantage (Li Drew, p. 3)
• Multimedia is defined as an interactive
  computer-mediated presentation that includes at
  least two of the following elements text, sound,
  still graphic images, motion graphics, and
  animation (p. 4, Tannenbaum)

6
Multimedia

• Presentation controlled by a computer
• standard components e.g., monitor, CPU,
  keyboard
• Some necessary technologies
• Digitization media (e.g., image) acquisition,
  Storage (large file sizes) Formats
• 2D graphics, digital video, digital sound,
  animation, 3D graphics modeling
• Mixing, Synchronization
• Reproduction, Transmission
• Display of text, graphics, sound, and other data
• Real-time response requirements
• Multimedia integration authoring
• Attention to effective communication

7
Why Multimedia?

• Primary learning assumption

8
Primary Learning Assumption of Multimedia

• people learn more when they are actively engaged
  in the learning process, interacting with the
  instructional materials and exercising some
  control employing several different senses
  and enjoying entertaining presentations (p. 24,
  Tannenbaum)

9
Employing Several Different Senses

• The information arriving at the persons (users)
  senses needs to be organized or coordinated

10
Different media channels

• Media channels can reinforce each other
• Or provide different information
• Example
• A person talking has an audio channel and a
  visual channel
• The channels naturally reinforce each other
• Audio signal occurs in strong correlation with
  the visual signal
• Although, interestingly, the visual motion often
  precedes the speech audio in time (Murai
  Nakamura, 2001)
