Study Notes

Definition of Multimedia

"Multimedia" combines "multi" (various) and "media" (hardware/software for communication).
Examples of hardware: radio, television, computer, mobile phone.
Examples of software: email, Yahoo Messenger, Multimedia Message Service (MMS), video conferencing.

Multimedia in Information and Communication Technology (ICT)

Multimedia involves interaction with computers for tasks like information retrieval and gaming.
Key elements of a multimedia system include text, graphics, audio, video, and animation.

Key Elements

Text

Fundamental element in multimedia; involves type, size, color, and background.
Hypertext allows linking to other media/screens via text.
Effective multimedia text considers position, message length, and legibility.

Graphics

Graphics enhance application appeal and illustrate concepts through images.
Two types of graphics:
- Bitmaps: Captured images from devices (cameras, scanners).
- Vector: Computer-drawn images, requiring less memory.

Audio

Audio incorporates speech, music, and sound effects.
Types of audio:
- Analog: Original sound signals.
- Digital: Sampled versions of analog signals, primarily used in multimedia.

Video

Digital video increasingly popular in multimedia for its ease of editing and quality maintenance.
Digital video files are large, making transfer time-consuming, especially over the Internet.

Animation

Creates the illusion of movement using static images.
Two categories:
- 2D: Two-dimensional animations.
- 3D: Three-dimensional animations.

Standard File Formats

Multimedia elements have various standard file formats, influencing the type of content used for development.

Interactivity in Multimedia

Linear interactivity: Users control play and stop without altering the content flow.
Non-linear interactivity: Users choose which content sections to view, enhancing engagement and exploration.

Context

Lessons should be relevant to titles; all components (introduction, content, evaluation) must relate to the main subject.

Navigation facilitates user movement through menus and screens, enhancing usability.

Search

Systems need search functions for easy keyword and glossary lookup, enabling users to sort and preview information.

Learnability

Systems should provide support information and help to enhance user understanding and engagement.

Flexibility

Users should navigate freely through all sections without restrictions or limitations.

Personalisation

Users can customize their learning experience and interface settings for enhanced relevance and engagement.

Multimedia Applications

Effective in delivering information and enhancing learning experiences, especially in fields like medicine.
Develops higher-order thinking skills and supports complex procedure simulations.

Multimedia Software

Programs capable of playing/recording audio and video, crucial for creating multimedia content.
Tools include Adobe Photoshop (graphics), Adobe Illustrator (vector graphics), Adobe Premiere Pro (video editing), and Adobe After Effects (motion graphics).

Common Multimedia File Formats

Video: .mp4, .wmv, .mov, .avi
Audio: .mp3, .wma, .aac, .wav
Images: .jpeg, .png, .gif, .tiff
