1 A Taxonomy of Tasks and Visualizations for Multimedia Histories of Casual Interactions Charlotte Tang, Gregor McEwan & Saul Greenberg University of Calgary

2 The Message You can design a tool for visualizing histories of multimedia casual interactions using our taxonomy of tasks and visualizations

3 Casual Interaction Background

4 Casual Interaction Hi Mary Background

5 Casual Interaction Hi guys! Oh, there’s Sally! Ask her along. Background

6 Distance impairs casual interaction Background

7 Technologies for casual interaction Help bring the sense of cohesion and proximity Background

8 Messy Board Background (Fass, 2002)

9 Notification Collage (NC) (Greenberg & Rounding, 2001) Background Note: Video NCclip.WMV is played here

10 VisStreams Background

11 VisStreams Background Note: Video VisStreamsWithAudio1.WMV is played here

12 The Study 5 days of activities 13 computer science students All used the NC for communication All were doing research in HCI or InfoVis

13 Problem What requirements should a tool for visualizing histories of multimedia casual interaction support? –Tasks –Visualizations The Study

14 Step 1: Brainstorming Tasks to perform Questions to ask The Study

15 Step 2: Data Visualization A booklet of interaction data PostIt TM notes & White board markers The Study

16 Example Visualization The Study

17 Visualization Close-up The Study

18 Analysis 1)Task Categories 2)Visualization parameters 3)Visualization views The Study

19 Task Categories Interaction primitives ConversationsRhythms & trends Descriptive statistics Community & social networks Perspective of Group Memberof Researcher Analysis (1)

20 Task Categories Interaction primitives ConversationsRhythms & trends Descriptive statistics Community & social networks I’m amazed how the slickness of the wet tarmack on the roads really comes through in the video snapshot.... Analysis (1)

21 Task Categories Interaction primitives ConversationsRhythms & trends Descriptive statistics Community & social networks Soccer practice Monday afternoon Who’s gonna bring the soccer balls and other 2 matches in a row this weekend, we’ll Photos taken on picnic day are posted here for you to Oh, the water there was so clear and blue!

26 Visualization Parameters Time scale Conversational granularity Level of detail Media element streams Data perspective Analysis (2)

27 Visualization Parameters Time scale Conversational granularity Level of detail Media element streams Data perspective Jan 2002 May months5 weeks3 days12 minutes Analysis (2)

28 Visualization Parameters Time scale Conversational granularity Level of detail Media element streams Data perspective Soccer practice Monday afternoon Who’s gonna bring the soccer balls and other 2 matches in a row this weekend, we’ll Analysis (2)

29 Visualization Parameters Time scale Conversational granularity Level of detail Media element streams Data perspective I hope he can feedback on it. Wow, Mike finished his article It’s in lab site Char is going to Halifax next Analysis (2)

30 Visualization Parameters Time scale Conversational granularity Level of detail Media element streams Data perspective Carrie Peter Bernard 8:0010:0012:0014:0016:00 Peter how are you Fine, how ae you? Is Saul around? I hope he can feedback on it. Wow, Mike finished his article It’s in lab site Char is going to Halifax next It’s raining bad now  Soccer practice still? Better weat water-proof outfit Anyone knows the toolkit? Analysis (2)

31 Visualization Parameters Time scale Conversational granularity Level of detail Media element streams Data perspective Can anyone direct me to appropriate papers for conversation theories? Sheelagh will know that but she’ll only be back next week. Why don’t you check the Communications faculty ? Analysis (2)

32 Summary Task categories Interaction primitives Conversations Rhythms & trends Descriptive statistics Community & social networks Visualization Parameters Time scale Conversational granularity Level of detail Media element streams Data perspective

33 Detail View 11:1511:2011:25 Mike R, I’ve brought the tripod back home to use. Ouch!!! When will you bring it back? I want to tape NCWed. Carman around? Yeah, let me turn the video on. Hey, Saul, what are you taping? Nice posture Harry Potter! Movie tonite? Analysis (3) : Task-centered views

34 Conversation View Greeting gestures Hiking in Canmore VisStreams development We’re going to have a pot luck dinner in Canmore Which trail are we going to hike? Hey, Mike What do you think about the overview? It looks good to me! Can I change their height and Analysis (3) : Task-centered views

35 Rhythms and Trends View (Begole et al., 2002) Analysis (3) : Task-centered views

36 Community and Social Structures (J. DiMicco, 2003) Joanie Analysis (3) : Task-centered views

37 Future Work Prototype tools based on the taxonomy Investigate how the tools actually used

38 The Message You can design a tool for visualizing histories of multimedia casual interactions using our taxonomy of tasks and visualizations
