Introduction to Interactive Media Interactive Media Components: Text
2
Introduction to Interactive Media Text Tradition Text properties are grounded in the print tradition. Typeface is a family of characters sharing a common design. –Arial –Chicago –New York –Palatino
3
Introduction to Interactive Media Choice of Typeface Sometimes the way in which the text is rendered communicates more than the words, themselves.
4
Introduction to Interactive Media Text Tradition Typefaces are commonly categorized as: – Serif – Sans serif – Script – Symbols
5
Introduction to Interactive Media Serif vs. Sans Serif Serif typefaces tend to look more traditional. Sans serif typefaces tend to look more modern.
6
Introduction to Interactive Media Text Tradition Font Complete set of characters of a particular typeface, style, and size. Monospaced fonts: same width assigned to each character. (typewriter type) Proportional fonts: adjust width based on shape.
7
Introduction to Interactive Media Text Tradition Case –Upper and lower case. –UPPERCASE TYPE FEELS LIKE IT IS SHOUTING AT YOU. IT ALSO TAKES LONGER TO READ BECAUSE EACH WORD TAKES ON A BLOCKY SHAPE. A a
8
Introduction to Interactive Media Text Tradition Weight – Line thickness of the typeface. – Arial Black has heavier weight. Kerning – Adjusting spacing between specific letters. Tracking – Adjusting spacing between all characters.
9
Introduction to Interactive Media Text Tradition Condensed/extended text –Narrow width of text / widen width of text. Leading –Spacing between lines. Alignment & Justification –Alignment positions text relative to document's margins. –Justification adjusts line length to produce straight edges on left and right margins.
10
Introduction to Interactive Media Effect of Manipulating Leading and Tracking Manipulating Type (via kerning, tracking, leading, etc…) can create a graphic element.
11
Introduction to Interactive Media Type as Design Type can serve as a design element.
12
Introduction to Interactive Media Computer Text Text in Interactive Media Applications is Text Generated on Screen How is this Different than Printed Text?
13
Introduction to Interactive Media Computer Text Codes Coding schemes assign a group of binary numbers to represent a digital character. ASCII – 7-bit code = 128 characters. – Extended ASCII or ASCII-8 = 256 characters. All computers understand ASCII.
14
Introduction to Interactive Media Font Technologies Two techniques for displaying text on computer: –Bitmapped fonts –Outline fonts
15
Introduction to Interactive Media Bitmapped Fonts Bitmap fonts consist of "pictures" of a typeface at specific sizes Every character is stored as a bitmapped letter, number, or symbol. –Require large memory and storage capacity.
16
Introduction to Interactive Media Bitmapped Fonts Advantages –Precise control over letter appearance. –Letters can be edited at pixel level. Disadvantages –Letters can't be easily scaled. –Requires large storage capacities.
17
Introduction to Interactive Media Outline Fonts Most fonts are outline fonts Store a description of the character to be displayed. –Description is a series of commands to create the letter on the computer display. Outline font technology: – Adobe Postscript – TrueType (collaboration of Apple and Microsoft)
18
Introduction to Interactive Media Anti-Aliasing – smoothing the lines – text on screen Text is displayed on a monitor as a pattern of pixels. –Squares that display curved or diagonal lines produce a stair- stepped effect called JAGGIES. Anti-aliasing creates a smooth edge by blending the color of the text with the color of the background.
19
Introduction to Interactive Media Installed Fonts – the Problem Fonts are not standardized across computer platforms. –If the font is not available on the computer, it will substitute one that is, e.g. Power –The result may not be acceptable. Solution –Use only widely available fonts. –Package the unique font with the application (e.g. embed with Flash).
20
Introduction to Interactive Media Multimedia Text Two main forms: –Editable: text produced by word processors or text editors. Easy to alter content. Can search and spell check. –Graphics: image of text that can be manipulated to produce a wide range of artistic effects. Make original word picture. Solves problem of installed fonts (used frequently in web site menu bars).
21
Introduction to Interactive Media Text and Interactivity Hypertext is linked text. –User interacts with links to trace relationships of words and ideas created by the author. Can be beneficial to provide options and additional information –Hyperlinks within content of a web site should be opened in a new window if they take the user to a new site.
22
Introduction to Interactive Media Portable Document Format PDF files maintain original formatting of documents across computer platforms. –Platform and application independent. –Support multiple media and user interaction. –Require a reader program to view the file and an application to convert a document to pdf format. Adobe Acrobat Reader is a free download. PDFCreator is a free open source converter.
23
Introduction to Interactive Media Guidelines for Text in Interactive Media Be selective. Be brief. Make text readable. Be consistent. Be respectful. Combine text with other media. Make text interactive.
