5. ©2011 2www.id-book.com Overview Being social Face to face conversations Remote conversations Tele-presence Co-presence Emergent social phenomena

6. 6 © Franz J. Kurfess Motivation ❖ Many activities involve communication or collaboration with other people. ❖ System design can discourage or support these activities. ❖ Computer support can enhance communication and collaboration. ❖ Better communication and collaboration can be very rewarding  for people, collectively or individually  for organizations.

7. 7 © Franz J. Kurfess Objectives ❖ Become familiar with social mechanisms for communication and collaboration. ❖ Analyze tasks and processes with respect to collaboration and communication. ❖ Be aware of potential ethnographic aspects. ❖ Integrate appropriate communication and collaboration mechanisms into systems to improve interaction design.

8. 8 Conversations

9. 9 © Franz J. Kurfess Conversation ❖ Structured exchange of information among a small group of people  frequently two persons  usually turn-taking  coherent flow of information  usually synchronous ❖ Natural language-based  not exclusively, however  additional auditory information  explicit visual cues  “body language” (implicit visual cues) ❖ Conversational Rules  mostly social conventions to make conversations go smoothly

10. 10 © Franz J. Kurfess FJK 2005 Activity: Conversing with Machines ❖ identify a suitable interaction between a user and a system, and analyze it from a conversational perspective  communication medium  sound, writing, buttons, …  language  natural vs. artificial, restricted vs. unrestricted  rules and conventions  social (“acceptable behavior”)  legal  technical

11. 11 © Franz J. Kurfess FJK 2005 Activity: Computer Support for Conversations ❖ identify a conversation between humans, and examine potential areas where computers can be used to improve aspects of the conversation  communication medium  sound, writing, diagrams, …  language  natural vs. artificial, restricted vs. unrestricted  mismatch in terminology  rules and conventions  social (“acceptable behavior”)  legal (contracts, agreements)  technical (processes)

12. ©2011 3www.id-book.com Conversational mechanisms Various mechanisms and ‘rules’ are followed when holding a conversation, e.g.mutual greetings A: Hi there B: Hi! C: Hi A: All right? C: Good, how’s it going? A: Fine, how are you? C: OK B: So-so. How’s life treating you?

13. ©2011 4www.id-book.com Being social Are F2F conversations being superseded by our social media interactions? How many friends do you have on Facebook, LinkedIn, vs real life? How much overlap? How are the ways we live and interact with one another changing? Are the established rules and etiquette still applicable to online and offline?

14. ©2011 5www.id-book.com Conversational rules Sacks et al. (1978) work on conversation analysis describe three basic rules: Rule 1: the current speaker chooses the next speaker by asking an opinion, question, or request Rule 2: another person decides to start speaking Rule 3: the current speaker continues talking

15. ©2011 6www.id-book.com Conversational rules Turn-taking used to coordinate conversation –A: Shall we meet at 8? –B: Um, can we meet a bit later? –A: Shall we meet at 8? –B: Wow, look at him? –A: Yes what a funny hairdo! –B: Um, can we meet a bit later? Back channeling to signal to continue and following –Uh-uh, umm, ahh

16. ©2011 7www.id-book.com More conversational rules Farewell rituals –Bye then, see you, yer bye, see you later…. Implicit and explicit cues –e.g. looking at watch, fidgeting with coat and bags –explicitly saying “Oh dear, must go, look at the time, I’m late…”

17. ©2011 8www.id-book.com Breakdowns in conversation When someone says something that is misunderstood: –Speaker will repeat with emphasis: A: “this one?” B: “no, I meant that one!” –Also use tokens: Eh? Quoi? Huh? What?

18. ©2011 9www.id-book.com What happens in social media conversations? Do same conversational rules apply? Are there more breakdowns? How do people repair them for: –Phone? –email? –Instant messaging? –texting? –Skyping?

19. ©2011 10www.id-book.com Remote conversations Much research on how to support conversations when people are ‘at a distance’ from each other Many applications have been developed –e.g., email, videoconferencing, videophones, videoconferencing, instant messaging, chatrooms Do they mimic or move beyond existing ways of conversing?

20. ©2011 Early videophone and visualphone 11www.id-book.com

21. ©2011 12www.id-book.com VideoWindow system (Bellcore, 1989) Shared space that allowed people 50 miles apart to carry on a conversation as if in same room drinking coffee together 3 x 8 ft ‘picture-window’ between two sites with video and audio People did interact via the window but strange things happened (Kraut, 1990)

22. ©2011 13www.id-book.com Sketch of VideoWindow

23. ©2011 14www.id-book.com Findings of how VideoWindow System was used Talked constantly about the system Spoke more to other people in the same room rather than in other room When tried to get closer to someone in other place had opposite effect - went out of range of camera and microphone No way of monitoring this

24. ©2011 15www.id-book.com Skype success Global household name Seeing others on screen enables more intimacy than audio phone Enables people to get to know each other better Less awkward for young children –Like “to show, not tell” (Ames et al, 2010)

25. ©2011 16www.id-book.com 3D virtual worlds Second Life (2007) –Over 8 million users What kinds of conversation take place in these environments? VoIP versus chatroom talk? –Which is preferred and why?

26. ©2011 17www.id-book.com Second Life – The OU

27. ©2011 18www.id-book.com Facebook and Twitter Everyone uses them so what is there to learn? Used in emergencies, demos, etc., –e.g., users spread up-to-the minute info and retweet about how a wildfire or gas plume is moving –but can also start or fuel rumors, by adding news that is old or incorrect –more confusing than helpful

28. ©2011 19www.id-book.com Telepresence New technologies designed to allow a person to feel as if they were present in the other location –projecting their body movements, actions, voice and facial expressions to the other location or person –e.g. superimpose images of the other person on a workspace

29. ©2011 20www.id-book.com Portholes (Dourish and Bly, 1992) Regularly updated digitized images of people in their offices appeared on everyone’s desktop machines throughout day and night

30. ©2011 21www.id-book.com Clearboard (Ishii et al, 1993) Transparent board that shows other person’s facial expression on your board as you draw

31. ©2011 22www.id-book.com Hypermirror (Morikawa and Maesako, 1998) –allows people to feel as if they are in the same virtual place even though in physically different spaces (woman in white sweater is in a different room to the other three) People in different places are superimposed on the same screen to make them appear as if in same space

32. ©2011 23www.id-book.com Creating personal space in Hypermirror 2) Two in this room are invading the ‘virtual’ personal space of the other person by appearing to be physically on top of woman in white sweater 3) Two in the room move apart to allow person in other space more ‘virtual’ personal space

33. ©2011 24www.id-book.com Everyone happy

34. ©2011 25www.id-book.com How much realism? Is needed in telepresence to make it compelling? Telepresence rooms try make the remote people appear to be life-like by using multiple high def cameras with eye-tracking features and directional microphones Is skype just as good?

36. ©2011 27www.id-book.com Coordination mechanisms When a group of people act or interact together they need to coordinate themselves –e.g., playing football, navigating a ship They use: –verbal and non-verbal communication –schedules, rules, and conventions –shared external representations

37. ©2011 28www.id-book.com Co-presence Technologies that enable co-located groups to collaborate more effectively –when working, learning and socializing Examples: Smartboards, Surfaces, Wii and Kinect

38. ©2011 29www.id-book.com F2F coordinating mechanisms Talk is central Non-verbal also used to emphasize and as substitute –e.g. nods, shakes, winks, glances, gestures and hand-raising Formal meetings –explicit structures such as agendas, memos, and minutes are employed to coordinate the activity

39. ©2011 30www.id-book.com Schedules, rules and conventions Schedules used to organize regular activities in large organizations Formal rules, like the writing of monthly reports enable organizations to maintain order and keep track Conventions, like keeping quiet in a library, are a form of courtesy to others

40. ©2011 31www.id-book.com Shared external representations Common method used to coordinate collaborative activities, –e.g., checklists, tables, to-do lists They can provide external information on: –who is working on what –When it is being worked on –where it is being worked on –when a piece of work is supposed to be finished –whom it goes to next

41. ©2011 32www.id-book.com Collaborative technologies to support coordination There are a variety of software tools designed to support scheduling, planning and coordinating –e.g., group calendars, electronic schedulers, project management tools, and workflow tools Need to get balance between human and system control –too much system control and the users will rebel –too little control and the system breaks down

42. ©2011 33www.id-book.com Awareness mechanisms Involves knowing who is around, what is happening, and who is talking with whom Peripheral awareness –keeping an eye on things happening in the periphery of vision –Overhearing and overseeing - allows tracking of what others are doing without explicit cues

43. ©2011 34www.id-book.com Lo tech awareness mechanism

44. ©2011 35www.id-book.com Designing technologies to support awareness Provide awareness of others who are in different locations Workspace awareness: “the up-to-the- moment understanding of another person’s interaction with the shared workspace” (Gutwin and Greenberg, 2002) Examples: ReacTable and Reflect Table

47. ©2011 The Dynamo system 38www.id-book.com

48. ©2011 39www.id-book.com Notification systems Users notify others as opposed to being constantly monitored Provide information about shared objects and progress of collaborative tasks –example: Babble

49. ©2011 40www.id-book.com Babble (IBM, Erickson et al, 1999) Circle with marbles represents people taking part in conversation in a chatroom Those in the middle are doing the most chatting Those towards the outside are less active in the conversation

50. ©2011 41www.id-book.com What next? Besides perpetual sharing and broadcasting of information, knowledge, and personal content? Lifelogging –recording everything in one’s life and sharing Micro-chatting –beyond twittering and chatroulette?
