First, a bit about GGC/MediaWiki

MediaWiki Stuff: Internal Links/New Page Linking within the wiki (and creating a new page) placing [[myNewPage]] in edit window... ==> the link myNewPage showing up on your wiki page The first time you click on myNewPage... you will find yourself in the edit window for that new page If you put something on the new page, the next time you click myNewPage you will go to the new page

MediaWiki Stuff: Internal Links/New Page Fancier version placing [[myNewPage | New Page!]] in edit window... ==> the link New Page!]] showing up on your wiki page The first time you click on New Page!]]... you will find yourself in the edit window for that new page If you put something on the new page, the next time you click New Page!]] you will go to the new page

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: [ Go to Google!] placed on your page during an edit will show up on your page as Go to Google! and clicking on it would send you to

MediaWiki Stuff: Uploading files other than image files You can store many different kinds of file on the wiki for later downloading But only a few different kinds of files will display on the wiki Example: MSWord file called myMSWordFileName.doc Use the “Upload file” link upload the file to the wiki edit the Mediawiki page you want this file to show on put a link on the page with this format: [[Media:myMSWordFileName.doc]] save the edited page You will now see a link Media:myMSWordFileName.doc on your page and clicking it will cause it to download but not display

MediaWiki Stuff: PDF files PDF files can be displayed (rather than downloaded) inside the wiki If you upload a pdf and you put [[media:myFile.pdf]] in the page edit You will see media:myFile.pdf on your page and when you click it your file will be displayed, not downloaded Fancier form: [[media:myFile.pdf | my PDF file]] shows my PDF file on the page as the link displays the file called myFile.pdf when clicked ALSO: To make a pdf file on mac: file print save as pdf

Now to Chapter 1!

The Effect of Media Choice and the use of new Technology 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

New Media/New Technology Consider going from the SCROLL to the BOUND BOOK... HMMMmmmm... WR6hzZek

Different Media? Different Affordances affordances is a term from ecological psychology – – –different things afford different interaction –consider door knobs, levers, push-plates and pulls Don Norman and Psychology of Everyday Things

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

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 take notes in the margins

WWW vs Book Good 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? Did you read all the stuff that is there? –Book is easy, read front to back – not so much...

WWW vs Book Good 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?

New Media/New Technology Adoption It takes time for conventions concerning usage to be formed Consider the history of Film... –No sound –Performed sound –Recorded sound Later film developed its own forms Hitchcock told the story visually, long scenes Tarrentino accents everything with violence and quick cuts

New Media usage follows a predictable path At first the new form tries to act like the old form to make the new stuff look more familiar –Newsreels “copied” newspaper layouts –Desktop metaphor is an example of this Before desktop metaphor C: is all you got –few people used personal computers Alan Kay XEROX PARC personal computer usage exploded

What is Multimedia? Mix of audio, film, graphics, haptic –that address the different senses We are just beginning to understand what the possibilities are... We are just beginning to understand how to best build multimedia stuff –Mix of animation and live action The movie 300? The movie Sin City? Beowolf? –TV series 24 and the movie Phone Booth? several scenes are played simultaneously

In this class We are interested in media forms found on and transmitted across the Internet and how to manipulate them –audio –still images bitmapped vector graphics –moving images

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

Hypermedia Time-based uses time as its central organizing theme –Film –Audio Page-based uses a page as its central organizing theme –Book –Internet?

Interactive? Yes and No Yes: Programs appear interactive, but only within the constraints placed on the interaction by the programmer and the interaction designer –Myst looked like a real world but you only had a few choices you could make No: Improvisation (on the part of the user) can’t happen unless it is provided for in advance by the interaction designer and the programmer

How do you interact? 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

Ethical Considerations Is technology neutral? Does human usage define it as ethical or unethical? BUT: new technology affords new means of interaction and opportunities for behavior that previously didn’t exist Online rape? –MUD: Multiple User Domain –

Social Considerations: Access Expensive Reduce the world to 100 people.. – ate.asphttp:// ate.asp Access to internet worldwide? 1/100 would have a computer But... there are internet cafes

Social Considerations: Access What about people with disabilities? – Blind prior to the desktop metaphor this was the largest group of online users –Screen readers images are provided alternate text representations

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:

In Summary Media is changing Internet is changing Affecting us socially Giving us new capabilities Challenging our views of legality Allowing new uses and new interactions This class is about media and how it works
