Leading

the space between lines.

font

• A ____ is a collection of characters of a single size and style belonging to a particular typeface family.

Clipping

- Used to get rid of unwanted background noise -Occurs when the max or min values are reached -May cause distortion or may amplify distortion that is already present -Avoid by changing the volume on input source when recording

integer (quantization).

The value of each sample is rounded off to the nearest

typeface

A _____ is a family of graphic characters, often with many type sizes and styles.

Users: • Demographics • Personal views • Viewing environment • Skill and knowledge level Hardware • Why is this important? • What should we attempt to find? • What is our projected delivery platform?

Audience Analysis

How easily and comfortably a typeset can be read Factors affecting _____: - Size - Background and foreground colors - Style - Leading Legibility

-Factors affecting legibility of text:

- Photo-realistic images - Complex drawings - Images that require fine detail

Bitmaps are an image format suited for creation of:

44.1 kHz 16 bit

Cd redbook standard

• Getting the user's attention • Set up the correct emotional atmosphere - Frame of mind • Deliver the message

Communicating the Message

Harmonies

Complementary. across the color wheel

Vector-drawn

Complex drawings

hypertext system

enables the user to navigate through text in a non-linear way.

• Interviews: structured, unstructured • Questionnaires • Observation • Sampling

Determining Platform Requirements

samples.

Digital audio data is the actual representation of a sound, stored in the form of ________

Cascading Style Sheets (CSS)

Dynamic HTML uses _____ for greater control over design. Multimedia is the combination of text graphics, and audio elements into a single presentation.

Design - Clarity and flow • Writing • Graphic illustration • Performance - Is system fast enough for media processing?

Execution

- Boldface - Italic - Underlining - Outlining

Font styles include

• Text • Images • Video • Animation • Audio

Forms of Media

The standard document format used for web pages is called

HTML

Sampling rate

Higher rate, better representation, or quality multimedia 441 kHz cd - 2202 kHz and 11

used for: - Electronic publishing and reference works - Technical documentation - Educational courseware - Interactive kiosks - Electronic catalogs

Hypertext systems

Requires different design methods and technologies • Requires different technologies to store, load and display on a device • Effective in some areas of communication but perhaps not efficient in communicating all messages

Implications (considerations) of different types of media

Cross-platform formats

JPEG, GIF, and PNG - Most commonly used format on the Web

jaggies

Jaggered squares around text

Hypermedia

Links Nodes Anchors Hypertext systems

color palettes

Mathematical tables that define the color of pixels displayed on the screen.

Does it enhance the emotional impact? • Does it make a story point? • Does it help with information delivery? • Does it help with the passage of time? • Does it provide a transition?

Media Considerations

Conveying the message Getting the audience's attention • Text • Illustrations • Animation / video* • Audio* • Interaction

Message Analysis

a combination of text, art, sound, animation, and video

Multimedia

Dithering

Process whereby the color value of each pixel is changed to the closest matching color value in the target palette. - This is done using a mathematical algorithm

linear

Project that are not interactive

nonlinear

Projects where users are given navigational control

1. Planning and Costing 2. Look and feel 3. Prototype or proof of concept 4. Designing and Producing 5. Testing 6. Delivering

Stages of a Project

• Communicating the message • Execution • Accountability and Measurability

Three main areas of concern in Multimedia Project

Graphic designers choose typefaces for their projects but use fonts to create the finished art.

Typeface vs. font

Computer-aided design (CAD) programs - Graphic artists designing for the print media - 3-D animation programs - Applications requiring drawing of graphic shapes

Vector-drawn images are used in the following areas:

- Vector images use less memory space and have a smaller file size as compared to bitmaps. - For the Web, pages that use vector graphics in plug-ins download faster and, when used for animation, draw faster than bitmaps. Vector images cannot be used for photorealistic images. - Vector images require a plug-in for Web-based display. - Bitmaps are not easily scalable and resizable. - Bitmaps can be converted to vector images using autotracing.

Vector-drawn images versus bitmaps

• Most common form of communication • Words or symbols • Design objects using words with... • Precise meaning • Powerful meaning

Why is text so important?

Additive color

a color is created by combining colored light sources in three primary colors - red, green, and blue (RGB). - TV and computer monitors use this method.

Nodes

are accessible topics, documents, messages, and content elements. Links form the backbone of a knowledge access system.

Discordant colors

are colors that are farther than around 30 degrees apart on the color wheel and are not complementary or part of a triad.

Symbols

are concentrated text in the form of stand-alone graphic constructs. - They are used to convey meaningful messages.

Links

are connections between conceptual elements, navigation pathways and menus.

Character metrics

are the general measurements applied to individual characters

Subtractive color

created by combining colored media such as paints or ink. - Process used to create color in printing. primary colors: cyan, magenta, and yellow (CMY).

Anti-aliasing

creates "smooth" boundaries between colors. Allows text to be re-sized without jaggies

Bitmap

data matrix describing the individual dots of an image. - known as paint graphics. - made up of individual dots or picture elements known as pixels or pels.

- 1 bit, 2 colors -4 bit 16 colors 8 bit 256 colors 24 bit millions of colors

different ways to specify sizes

Readability

ease with which language is understood

Hypertext

is defined as the organized cross-linking of words, images, and other Web elements.

Anchors

is defined as the reference from one document to another document, image, sound, or file on the Web.

Color

is one of the most vital components of multimedia.

Digital audio data ans: samples.

is the actual representation of sound, stored in the form of _____

Kerning

is the spacing between character pairs

Font sizes

measured in points (0.0138 in or 1/72 inch

First • "The message must be delivered or the production is a waste of time and money." Second • "Entertainment is defined as the stimulation of any emotion or set of emotions that can be classified as positive in nature. Third • "The tools and skills required to create a good presentation are so plentiful that there is no excuse for settling for less than the highest quality execution." Fourth • "The effectiveness of the presentation must be measured and analyzed."
