Types of Multimedia
• Interactive multimedia
• Hyperactive multimedia
• Linear multimedia
![Page 11: MULTIMEDIA Programming. Chapter 1 Introduction to Multimedia.](https://reader035.fdocuments.us/reader035/viewer/2022081501/56649d795503460f94a5d79c/html5/thumbnails/11.jpg)
Interactive Multimedia
• Allows the user to control–what and
–when the elements are delivered
![Page 12: MULTIMEDIA Programming. Chapter 1 Introduction to Multimedia.](https://reader035.fdocuments.us/reader035/viewer/2022081501/56649d795503460f94a5d79c/html5/thumbnails/12.jpg)
Hypermedia
• Interactive Multimedia which
provides a structure of linked elements through which the user
can navigate
![Page 13: MULTIMEDIA Programming. Chapter 1 Introduction to Multimedia.](https://reader035.fdocuments.us/reader035/viewer/2022081501/56649d795503460f94a5d79c/html5/thumbnails/13.jpg)
Multimedia Project
• Software vehicle, messages and content presented on a computer or TV screen–Multimedia title - if sold or shipped to
users with or without instructions–Web page if on the www and composed
of HTML or DHTML ( Dynamic Hypertext Markup Language)
![Page 14: MULTIMEDIA Programming. Chapter 1 Introduction to Multimedia.](https://reader035.fdocuments.us/reader035/viewer/2022081501/56649d795503460f94a5d79c/html5/thumbnails/14.jpg)
Multimedia Project
• Linear - users watch from beginning to end
• Non-linear and interactive - users are given navigational control and can wonder through the content
![Page 15: MULTIMEDIA Programming. Chapter 1 Introduction to Multimedia.](https://reader035.fdocuments.us/reader035/viewer/2022081501/56649d795503460f94a5d79c/html5/thumbnails/15.jpg)
Authoring Tools
• Multimedia elements are “sewn” together using tools like Authorware – to provide facilities for creating and
editing text and images– have extensions to drive videodisc
players and other peripherals– playback the sound and movie elements
created with other tools
![Page 16: MULTIMEDIA Programming. Chapter 1 Introduction to Multimedia.](https://reader035.fdocuments.us/reader035/viewer/2022081501/56649d795503460f94a5d79c/html5/thumbnails/16.jpg)
Requirements• Multimedia requires:– large amounts of digital memory and
network bandwidth;– GUI (“gooey”) - a graphical user interface– CD-Rom or DVD technology for storage
In the future these may be replaced by “connected” fiber, and radio/cellular technology
– DVD – Digital Versatile Disc

Delivering and Using Multimedia• Multimedia demands bandwidth• CD-ROMs hold 650-700 MB (80
minutes of full screen video)• DVD-ROMs hold 4.7-18 GB• Multimedia can be delivered on line
![Page 18: MULTIMEDIA Programming. Chapter 1 Introduction to Multimedia.](https://reader035.fdocuments.us/reader035/viewer/2022081501/56649d795503460f94a5d79c/html5/thumbnails/18.jpg)
Why Multimedia?
• Multimedia enhances learning, memory and retention– audio stimulation - 20% retention rate– audio/visual - up to 30% retention rate– interactive multimedia - up to 60%
retention rate

![Page 22: MULTIMEDIA Programming. Chapter 1 Introduction to Multimedia.](https://reader035.fdocuments.us/reader035/viewer/2022081501/56649d795503460f94a5d79c/html5/thumbnails/22.jpg)
New Technologies• VR- Virtual Reality– Goggles, helmets, gloves, etc. place
users “inside” a life-like experience – View changes as user moves forward,
left/right, etc.– Composed of thousands of geometric to
be realistic–Will require new standards (VRML) for
transmitting virtual worlds on the web
