Prelim- Lesson 1 Flashcards
computer information can be
represented through audio, video, and animation in addition to traditional media (i.e., text, graphics/drawings, and images)
Multimedia
Composed of two parts
multi(multus) + media(medium)
the field concerned with the computer-controlled integration of text, graphics, still and moving images, animation, sounds and any other medium where every type of information can be represented, stored,
transmitted and processed digitally. (Marshall, 2011)
Digital Multimedia
application which uses a collection of multiple media sources e.g. text, graphics, images,sound/audio, animation and/or video.
Multimedia Application
a text which contains links to other texts.
The term was invented by
Hypertext
Ted Nelson around 1965
Traversal through pages of hypertext is therefore usually non-linear (as indicated below).
Hypertext Navigation
not constrained to be text-based. It can include other media, e.g., graphics, images, and especially the continuous media – sound and video.
Hypermedia
Example Hypermedia Applications
The World Wide Web (WWW)
PowerPoint
Adobe Acrobat (or other PDF software)
Adobe Flash
Examples of Multimedia Applications include:
●World Wide Web
● Multimedia Authoring, (e.g., Adobe/Macromedia Director)
● Hypermedia courseware
● Video-on-demand
● Interactive TV
refers to the transformative ways that people share information and ideas through creative uses of technology.
Interactive Television
adds digital elements to a live view often by using the camera on a smartphone.
experiences include Snapchat lenses and the game Pokemon Go.
Augmented reality (AR)
implies a complete immersion experience that shuts out the physical world.
Vive, Oculus Rift or Google Cardboard, users can be transported into a number of real-world
Virtual reality (VR)
experience, which combines elements
of both AR and VR, real-world and digital objects interact. technology is just now starting to take off with Microsoft’s HoloLens one of the most notable early mixed reality apparatuses.
Mixed Reality (MR)
an umbrella term that covers all of the various technologies that enhance our senses, whether they’re providing additional information about the actual world or creating totally unreal, simulated worlds for us to experience. It includes Virtual Reality (VR), Augmented Reality (AR) and Mixed Reality (MR) technologies.
Extended Reality (XR)
characterized by the processing, storage, generation, manipulation and rendition of Multimedia information.

Display Devices
Elements of Multimedia
Audio
Graphic
Computer-generated (text)
Video
Interactivity
signals are continuous analog signals.
Input: microphones and then digitized and stored
Audio
constructed by the composition of primitive objects such as lines, polygons, circles, curves and arcs. usually editable or revisable (unlike Images).
Graphic
refers to waves that travel through air and that are received by the ear, human or otherwise.
Sound
refers to sound that has been, in some way or another be it digital or analog, processed electronically.
Audio
A few words appearing in a predominantly graphic multimedia system can have a powerful effect. (ex. Subtitles) Source: keyboard, speech input, optical character recognition, data stored on disk
Computer-generated (text)
together they are the most effective means of communication that can be a part of the multimedia system
Video
multimedia system, if the user has the ability to control what elements are delivered and when, the system is called an
Interactivity
Example of interactivity
Mass Media
Television
Film
Radio
Newspapers
One way Communication
A complicated process, usually involving many people. Typically, one or more of the following people may be involved in making a
Multimedia Production
Multimedia Production
Producer
Multimedia Designer
Subject Matter Expert
Programmer/Author
Instructional Designer
their education, technology skill level, needs, and so on. Also gather information on the content to be presented and the system on which the multimedia product will be used.
Research and Analysis
Stages in Multimedia Production
1.SCRIPTING/FLOWCHARTING
2.STORYBOARDING
3.CONSTRUCTION/COLLECTION OF MEDIA ELEMENTS
4.TESTING
involves deciding the overall structure of the multimedia project. This is done by placing the various segments of the project in order, using arrows
SCRIPTING/FLOWCHARTING
detailed design plan that the designer
creates, indicating what each screen
looks like, which media elements are
used in the screen, and all the
specifications of the media elements.
where the detailed visualization of the
multimedia system takes place.
STORYBOARDING
Usually after the storyboard, a prototype is made and tested, and the design is reviewed.
CONSTRUCTION/COLLECTION OF MEDIA ELEMENTS
The final production stage.determines that everything works on the system it is supposed to work on and also whether typical users will find the design intuitive enough.
TESTING
