2. Open Book Question! What is one book that is meant to be read in a non-linear form?

3. How to make a pdf on a Mac Any file that is open on a Mac Pull File down to Print In the lower left hand corner of the print window Click “PDF” Then select “Save as pdf”

4. On the wiki… You can save (and later download) –word files (.doc ) –powerpoint files (.ppt) –pdf files (.pdf) –audio files (.au.mpg & others) –video files (.mov & others) –image files (.jpg.png & others)

5. On the wiki… You can display –text –image files (.jpg.png & others) shortFormatHelp –http://en.wikipedia.org/wiki/Wikipedia:Cheatsheet longerFormatHelp –http://en.wikipedia.org/wiki/Wikipedia:How_to_edit_a_page

6. Now to Chapter 1!

7. Telling a story The telling of stories has existed as long as humans have been on earth. So… how do you tell a story? It depends on what media you are going to use… –Is it spoken to a live audience around a campfire? –Is it an audio recording that is played? –Is it written as text in a book or magazine? –Is it captured in a painting? –Is it told using pictures in a photo album? –Is it performed as a play on stage? –Is it recorded on video and played back? –Is it video that is streaming over the web? –Is it captured in the form of a video game?

8. The media you choose affects the way the story is told If you are using printed text –you must describe things well Using still images? –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 the other way around? Video game? –moving images accented with sound

9. New Media/New Technology Consider if you had spent your life working with the SCROLL… and you were asked to change to the BOUND BOOK... HMMMmmmm... http://www.youtube.com/watch?v=xFA WR6hzZek

10. Different Media? Different Affordances! affordances is a term from ecological psychology borrowed by Don Norman –different things afford different interaction handles to pull door open push plates to push door open door levers rotate to open door knobs… hmmm… I hate fake door knobs! –http://en.wikipedia.org/wiki/Affordancehttp://en.wikipedia.org/wiki/Affordance –http://en.wikipedia.org/wiki/Ecological_psychologyhttp://en.wikipedia.org/wiki/Ecological_psychology –http://en.wikipedia.org/wiki/Don_Normanhttp://en.wikipedia.org/wiki/Don_Norman

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

12. Scroll, Book and now... Web-based media –you can consume it in any order you want –links take you to a place (and back!) does a book do this? –the page is in one place… one change changes everyone’s version Now compare that to the Book –doesn’t allow this universal change –doesn’t take you back... but you can stick a piece of paper or a finger in it to hold your place… or fold down the corner of the page –you can take notes in the margins

13. Web-based vs Book Web-based media –allows corrections immediately to everyone –but no history kept like with book editions you go back to “the same place” and it’s different... were you mistaken or did it change? http://www.archive.org/index.php Did you read everything? –Book is easy, read front to back –WWW... not so much...

14. Web-based vs Book Web-based 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 then reach for the search tool? …and then you feel kinda foolish?

15. New Media/New Technology Adoption It takes time for conventions concerning usage to be formed Consider the history of Film... –No sound –then performed sound –then recorded sound With time… film developed its own forms Hitchcock told the story visually, long sweeping scenes Tarrentino accents the violence with rapid, quick cuts

16. Usage of New Media follows a predictable path At first the new form tries to act like the old form to make the new stuff look more familiar –In the movies, Newsreels “copied” newspaper-like layouts –With computers, the desktop metaphor “copied” the office desk http://en.wikipedia.org/wiki/Alan_Kay –Alan Kay, XEROX PARC –“The best way to predict the future is to invent it” –personal computer usage exploded –before desktop metaphor C:/ is all you got & few people used personal computers

17. So… What is Multimedia? Mix of audio, film, graphics, haptic (what’s haptic?) –these address 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

18. In this class We are interested in media forms found on and transmitted across the Internet and how to manipulate them We will build them as projects –audio –still images bitmapped vector graphics –moving images video camera 3D animation

19. Static vs Time-based media Time-based –Media that changes over time Film Video Audio Static media –Media that doesn’t change over time Pages in a book Photos in an album Images on a webpage

20. Media Linearity Scroll - linear Book – linear… broken, but linear –Must turn the pages –but… Table of Contents and Index allow some non-linearity –encyclopedia and dictionaries are media that are meant to be used in a non-linear manner Film/Videotape - linear DVD – primarily linear –Chapters allow some non-linearity

22. Nonlinearity Supported through computer-based media –Takes the form of hypermedia –Web pages links to other pages, other parts of pages –Interactive video games you go to different parts of the game depending on your input

25. But is hypermedia 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 planned and provided for in advance by the interaction designer and the programmer

26. Interaction with computer-based media is through a user interface Human Computer Interaction –This is my academic field There are standard ways to interact with computer-based media –buttons –sliders –radio buttons –check boxes –pull-down menus –pop-up menus

27. Internet broadens its scope In the ’90s the internet was seen as a source... –you go to the internet to “look something up” –its use was seen to have an economic advantage… you 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/Podcasthttp://en.wikipedia.org/wiki/Podcast

28. In Summary Media is changing Internet is changing Affecting us socially –we send email to people who are in the same room Giving us new capabilities ways to interact –mosquito ring tones Challenging our views of legality –it’s on the web, can I use it without permission? Challenging our view of appropriate behavior –spam for instance Allowing new uses and new interactions This class is about media and how it works
