 Multimedia is usually recorded and

played, displayed or accessed by information content processing devices, such as computerized and electronic devices, but can also be part of a live performance (laser show).

 the combination of two or more

media types, to effectively create a sequence of events that will communicate an idea usually with both sound and visual support.  Typically, multimedia productions are

developed and controlled by computer.

 The slide presentation has been the cornerstone of family,

educational, and business presentations for decades.

 The term "multimedia" was coined by Bob Goldstein (later

'Bobb Goldsteinn') to promote the July 1966 opening of history "LightWorks at L'Oursin" show at Southampton, Long Island.

 In the 1970s, the slide show format was introduced to

specialized computers, designed to control slide shows.

 In the 1980s, personal computers were

introduced that allowed graphic elements to be “cut” and “pasted” from one document to another.

 In the 1990s, computer manufacturers

made their systems more accessible to third-party developers who were anxious to design and distribute their wares to the marketplace. During this phase, industry rolled to the launching pad.

1984 – 1987  simple slide shows  basic interactivity

1988 – 1992   faster processors  sophisticated graphical interface  interactive environments grow  

1993 – 1998  CD quality sound  3-D animation  presentation software enhanced  sophisticated authoring

environments  connection to externals  cross platform development

Categorization of multimedia: Linear active content

Non-linear content

 progresses without any

navigation control for the viewer. Ex. cinema presentation.

 offers user interactivity

to control progress as used with a computer game or used in selfpaced computer based training. Hypermedia is an example of non-linear content.

Areas where multimedia processes are beneficial:  Creative Industries  Education/Edutainment  Engineering  Industry  Mathematical and scientific research  Medicine  Document Imaging

a. Creative industries  Creative industries use multimedia for a variety of

purposes ranging from fine arts, to entertainment, to commercial art, to journalism, to media and software services provided for any of the industries.  An individual multimedia designer may cover the

spectrum throughout their career. Request for their skills range from technical, to analytical, to creative.

a.1.Commercial  Much of the electronic old and new media used by

commercial artists is multimedia.

 Exciting presentations are used to grab and keep

attention in advertising. Business to business, and interoffice communications are often developed by creative services firms for advanced multimedia presentations beyond simple slide shows to sell ideas or liven-up training.

 Commercial multimedia developers may be hired

to design for governmental services and nonprofit services applications as well.

 

a.2. Entertainment and fine arts  In addition, multimedia is heavily used in the

entertainment industry, especially to develop special effects in movies and animations.

 Multimedia games are a popular pastime and

are software programs available either as CDROMs or online. Some video games also use multimedia features.

 Multimedia applications that allow users to

actively participate instead of just sitting by as passive recipients of information are called Interactive Multimedia.

b. Education    In Education, multimedia is used to produce

computer-based training courses (popularly called CBTs) and reference books like encyclopedia and almanacs.

 A CBT lets the user go through a series of

presentations, text about a particular topic, and associated illustrations in various information formats. Edutainment is an informal term used to describe combining education with entertainment, especially multimedia entertainment.

 

c. Engineering  Software

engineers may use multimedia in Computer Simulations for anything from entertainment to training such as military or industrial training. Multimedia for software interfaces are often done as a collaboration between creative professionals and software engineers.

 

d. Industry  In the Industrial sector, multimedia is used as a

way to help present information to shareholders, superiors and coworkers. Multimedia is also helpful for providing employee training, advertising and selling products all over the world via virtually unlimited web-based technologies.

e. Mathematical and scientific research    In

mathematical and scientific research, multimedia are 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. Representative research can be found in journals such as the Journal of Multimedia.

f. Medicine  In Medicine, doctors can get trained by

looking at a virtual surgery or they can simulate how the human body is affected by diseases spread by viruses and bacteria and then develop techniques to prevent it.

g. Document Imaging  Document Imaging is a technique that

takes hard copy of an image/document and converts it into a digital format.

DOING MULTIMEDIA...  

 You to have a strong knowledge of what hardware

and software products are going to work for you.

 Be prepared by knowing your software.  If

your choice is to use a computer-based presentation program, such as Microsoft PowerPoint, you can use the predesigned templates, artwork, sound and other features that these programs have to offer.

 

 

Multimedia Presentation Tips...

 Make sure that the proper software is installed.

This includes the version that you used to prepare your presentation.

 Having the proper fonts that are used in your

presentation is mandatory. Without matching fonts, your presentation text will not conform to your original design.

 Computer compatibility  Sound quality will differ from system to system  Screen colors will vary from monitor to monitor  Color depth can also be an issue

The Effectiveness of a presentation is based on three things:

1.The content presented 2.The quality of the image 3.The effective communication skills

of the presenter
