Entertainmen t

Education

Mathematical and scientific research

These industries produce computer games, develop animation for cartoons and movies. Learning has become more interesting and effective with educational programs such as ‘edutainment’ that is a combination of education and entertainment. It also used to produce computer-based training (self-access-learning) and reference books like encyclopedias and almanacs. In mathematical and scientific research, multimedia is mainly used for modeling and simulation. For example, a scientist can look at a molecular model of a particular substance and manipulate it to arrive at a new substance.

INTERACTIVITY OF MULTIMEDIA ( 4.1.3 ) Interactivity refers to the way users interact with a multimedia application or program. User can used input devices such as keyboard, joystick, mouse and touch screen to interact with multimedia application. There are two types of interactivity; linear and non-linear. Differentiate Between the Characteristics of Linear and Non-Linear Multimedia ( 4.1.3.1 ) Linear Interactivity Linear interactivity does not allow the user to control the sequence of the multimedia content Not interactive – user is the passive receiver - Documentary - Movie - Video Clip

ASPECT

Non-Linear Interactivity

Controlling the sequence

Non-Linear interactivity lets the user control the sequence of the multimedia content.

Interactivity

Interactive – two-way communication by using buttons or links ( hypertext or hypermedia )

Describe the Phases in Multimedia Production ( 4.3.3.1 ) Phase

Description Developer set the focus of the project.

Analysis

Design

Implementati on

The multimedia developers interview the clients to find out their needs and write the problem statement and a proposal. Eg. Developers will identify the project title, problem, objective, possible solution and target user. Refers to the planning of the design of the multimedia program to be developed. There are two popular tools used in the Design Phase, namely the flow chart and storyboard. The Implementation Phase refers to the process of converting the design plan into a multimedia program. This is the phase where the multimedia program is produced. In the Implementation Phase, we use the authoring tool to integrate the multimedia elements such as Toolbook Assistant 2004, Macromedia Authorware, Macromedia Director and others. The purpose of testing is to ensure that the program runs correctly without errors.

Testing

Example : test the content, interface and navigation of multimedia program. The multimedia developers will use a checklist to test the multimedia program. If there are any errors, the programmer will fix the program.

Evaluation

Publishing

Focuses on overall presentation and effectiveness of the multimedia. Selected users will use an Evaluation Form to try out the program and give feedback. Package their presentation using suitable software. Distribute the presentation for public viewing by CD or website.
