  2. Roll Call using Banner Student on roster, not in class? -hawkins@ggc.usg.edu Student in class not on roster? 5443 -- Philip Hawkins 5313 -- Kris Bone 5151 -- Laura Ledford 5876 -- Selena Darter/Heather Jenkins Last option -- 678-977-7264 (Philip's cell)

  3. MediaWiki Stuff: Internal Links To place an internal link to a specific page get the name of the linked-to page put it in double square brackets To link from anywhere inside the Mediawiki to the page named:What to do here and how to do it: you would enter this in your page edit: [[What to do here and how to do it:]] and then save the edit external concurrent edits

  4. MediaWiki Stuff: External Links To place an external link to a webpage get the URL of the linked-to page put it in double square brackets For example: [http://www.google.com/[To go to google!]] placed on your page during an edit will show up on your page as [To go to google!] and clicking on it would send you to http://www.google.com/

  5. MediaWiki Stuff: Concurrent Edits! So... two people editing the same page at the same time... what happens? They both open an edit window on the page and they both see the same text in that window They both change that page but they change it differently What happens?

  6. The Effect of Media Choice • The media you choose has an effect on the way the story is told • Print? you must describe things well • Still Image? you have to tell it visually by setting the scene • Film/Video? you have moving images and sound... does the sound emphasize the moving image or vice versa? • 3-D amusement ride? moving images, sound and some actual motion... 3 modalities

  7. New Media/New Technology • Consider going from the SCROLL to the BOUND BOOK... • HMMMmmmm... • http://www.youtube.com/watch%3Fv=pQHX-SjgQvQ%26mode=related%26search=

  8. Different Media?Different Affordances • affordances is a term from ecological psychology • http://en.wikipedia.org/wiki/Affordance • http://en.wikipedia.org/wiki/Ecological_psychology • different things afford different interaction • consider door knobs, levers, push-plates and pulls Don Norman and Psychology of Everyday Things http://en.wikipedia.org/wiki/Don_Norman

  9. The Scroll, Book & WWW • Scroll • can’t stack scrolls like books • can’t skip around except to beginning or end • but reading flows without the interruption of pages • Book • you can stack them • you can level a table leg with them! • but reading is interrupted by page turns • with TOC & page numbers you can skip around • with index & page #s you can go to a specific place

  10. Scroll, Book and now... • WWW! • you can consume it in any order you want • links take you to a place (and back!) • does a book do this? • it’s in one place and one change changes everyone’s version • Compare to the Book • doesn’t allow this universal change • doesn’t take you back... but you can stick a piece of paper or finger in it to hold your place or fold down the corner of the page • you can write in the margins

  11. WWW vs BookGood or Bad? • WWW allows corrections immediately to everyone • no history kept like with book editions • you go back to “the same place” and it’s different... were you wrong or did it change? • http://www.archive.org/index.php • Did you read all the stuff that is there? • Book is easy, read front to back • WWW... not so much...

  12. WWW vs BookGood or Bad? • WWW affords searching • You can Google it and find it • Book? Not so much.. • the Index will help if the thing you are looking for is in the index... • Ever read a book and think... where did I see this before? and reach for the find?

  13. New Media/New Technology Adoption • It takes time for conventions concerning usage to be formed • Consider film... • No sound • Performed sound • Recorded sound

  14. New Media usage follows a predictable path • At first the new form tries to act like the old form • Newsreels “copied” newspaper layouts • desktop metaphor is an example of this • makes it familiar • Later film developed its own forms • Hitchcock told the story visually, long scenes • Tarrentino accents everything with violence and quick cuts • But that’s film... is that multimedia? • Maybe...

  15. Multimedia? • The movie Sin City? • The movie 300? • TV series 24 and the movie Phone Booth? • several scenes are played simultaneously • Mix of audio, film and graphics • We are just beginning to understand what the possibilities are... • We are just beginning to understand how to best use it

  16. Delivery Mechanism? • Offline • scroll, book • Vinyl record • AudioTape • Film (mixed media... but the sound is visual) • Videotape • CD-ROM • DVD • Online • Over the Internet

  17. In this class • We are primarily interested in delivery over the Internet • We are interested in media forms found on the Internet and how to manipulate them • audio • still images • bitmapped • vector graphics • moving images

  18. Media Linearity • Scroll (mostly linear) • Book • You had to turn the pages • Table of Contents and Index allow some non-linearity • encyclopedia and dictionarys are meant to be used in a non-linear manner • Film/Videotape • DVD • Chapters allows some non-linearity

  19. Hypermedia • Mixture of time- and page- based media • Time-based uses time as its central organizing theme • Film • Audio • Page-based uses a page as its central organizing theme • Book • Internet?

  20. Interactivity within the Computer • Yes, interactive, but within the constraints placed on the interaction by the programmer of the interaction • Myst looked like a real world but you only had a few choices you could make • Improvisation (on the part of the user) can’t happen unless it is provided for in advance

  21. User Interface • This is central to what my specialty is: HCI • There are standard forms • buttons • sliders • radio buttons • check boxes • pull-down menus • The kind of stuff you see when using the computer on the internet • You can design your own

  22. Social and Ethical Considerations • Technology is neutral • Human usage defines it as ethical or unethical • BUT: new technology affords new means of interaction and opportunities for behavior that previously didn’t exist • Online rape? • http://en.wikipedia.org/wiki/MUD

  23. Access • Expensive • Reduce the world to 100 people.. • http://www.snopes.com/science/stats/populate.asp • Access to internet worldwide? 1/100 would have a computer • But... there are internet cafes

  24. Access... • What about disabilities? • Blind? • Screen readers • images are provided alternate text representations

  25. WWW use broadens • Initially seen as a “source”... you go to “look something up” • seen as economic in nature, only have to put stuff in one place and everybody can get to it • Now it is also a transmission medium • streaming content: live radio • streaming content: view tv shows online • podcasts: http://en.wikipedia.org/wiki/Podcast
