1. 269111 – Communication Technology in a Changing World Week 6 Dr. Ken Cosh

2. Recap  Introduction to Semiotics Saussure  Dyadic Model Peirce  Triadic Model

3. This Week  A little more on Semiotics  Communication and Collaboration Models Human Computer Interaction (Dix – Chapter 14)

4. But First  Remember “Layers” TCP/IP  Application Layer  Transport Layer  Internet Layer  Link Layer Today we’ll look at a different set of layers  The Semiotic Ladder

5. The Semiotic Ladder  Social World  Pragmatics  Semantics  Syntactics  Empirics  Physical World

6. The Semiotic Ladder  Physical World

7. The Semiotic Ladder  Empirics  Physical World

8. The Semiotic Ladder  Syntactics  Empirics  Physical World

9. The Semiotic Ladder  Semantics  Syntactics  Empirics  Physical World

10. The Semiotic Ladder  Pragmatics  Semantics  Syntactics  Empirics  Physical World

11. The Semiotic Ladder  Social World  Pragmatics  Semantics  Syntactics  Emprirics  Physical World

12. Communicating via signs  If all communication is carried by signs  For communication to succeed we need to consider all the rungs on the Semiotic Ladder

13. Face to Face Communication  Primitive In terms of technology  Sophisticated In terms of complex interplay between different channels Not just speech and hearing  Also body language & eye gaze

14. Personal Space  How much space do you need? Different cultures allow different distances Environmental factors (such as noise) affect space But can you be comfortable?  What does this have to do with technology?

15. Video Conferencing #1

16. Video Conferencing #2

17. Video Conferencing #3

18. Solution?  Can I control the zoom on Tom’s camera, and he control mine?

19. Eye Gaze  What’s it for? Lovers Checking attention Conveying interest / confusion / boredom Authority / Power Building a bond  How about on video conferences?

20. Video Conferencing #4

21. Gestures  “Lets move this one there…”  Technological Assistance Group Pointer Shared Work Surface

22. The Power of “Um”  Aha!  Erm!  Hmmm…!  Er!  Um!  Uhh!

23. “Back Channels”  For Confirmation / Interruption  Electronic communication reduces the channels available; Sight Sound Gesture  As we lose channels, we lose back channel responses

24. Context  Context helps us understand, and back channels provide context;  Internal context Depending on previous utterances  External context Depending on the environment

25. “Do you want one?”

28. Turn taking  A conversation is a series of turns… I could request a ‘turn’ with “well, uh…” You could offer a ‘turn’ with “what do you think?”  Often turns are signified with a pause or gap in conversation. We live in a physical world, and physics says communication can not be instant…  Quick(er), but not instant Given these pauses are short, often the pauses are lost during telecommunication  Leading to confused conversations

29. Breakdown  A: Isn’t that beautiful?  B: The symmetry of the branches  A: How some people can dislike them I can’t understand.  B: Yes, the rangers should cull those deer, they strip the bark terribly in winter…

30. Repair  We are efficient at repairing communication breakdowns  However with electronic communication Lack of redundant channels Reduced turn taking frequency Reduced back channels  In reality it isn’t the breakdowns that cause problems, but the inability to recover from them.

31. Constructing a shared understanding  What is different between reading a book, and sitting in class? Here we can build a common ground  Much of communication is concerned with building common ground Utterances should be relevant & helpful  Relevant – continuing the current topic  Helpful – considering the listeners knowledge & understanding

32. Where is it?  “Just passed the pub…” Assuming we know which pub, this is relevant and helpful  It creates a common ground within the conversation It doesn’t matter that “A” thinks of the pub with memories of a great party, while “B” has never been, but has seen the sign. i.e. we don’t necessarily need the same sense of individual signifiers if the conversation leads us to the same global sense.

33. Text Based Communication  Common & Familiar From letters to Google wave  Very different style from face-to-face communication Discrete: directed messages such as email, with no explicit connection between messages Linear: Participants messages added in temporal order to a single transcript Non-linear: messages are linked together in hypertext fashion Spatial: Messages arranged across 2D surface

34. Back Channels  Text based communication loses channels Gesture, Body Language, Facial Expressions  Loss of Affective State of speaker Happy, Sad, Angry, Humorous  Loss of Illocutionary Force of the message Importance, Urgency

35. Emoticons  Emoticons are often used to convey this :-) ;-)

36. Netspeak  LOLBRB  BBLIDK  WTFGTG  ASLRL  ROFLMAO555  PRWNIFOC  2BHFOOBAR  GNOCIMHO  J/KL8R  NOOB

37. Emotion  Text based communication is often more heated, by calmer conversants Stronger language, as message has to be explicit Emotionally distanced, often time to calm down between messages

38. Email culture  Becoming more important Originally Email was unreliable  “I didn’t get it” ;) No guilt felt Originally we wouldn’t react the same way to an email as a formal letter  But different cultures treat email differently

39. Turn Taking  Different environments Cotemporality?  Message is seen as soon as it is typed Simultaneity?  Participants send and receive at the same time Sequential?  Utterances are ordered  How often have you misunderstood an online chat conversation due to sequential issues?

40. Overlapping  A: How many should be in the group?  B: Maybe this could be one of the four strongest reasons?  A: What do you mean?  B: I agree  A: Hang on?  B: What did you mean?

41. Group discussions  When multiple users chat simultaneously, these issues grow: Alison: Brian’s got some lovely roses Brian: I’m afraid they are covered in greenfly Clarise: I’ve seen them, they’re beautiful  Google Wave?

42. Group Project  How did the Google Docs project go?  How did you work as a group?  In what ways was Google Docs useful?  In what ways was Google Docs unhelpful?  What alternative collaboration means would be useful?
