7 Definition of Interaction Interaction (HCI: Human-Computer Interaction) Interaction in a sense previously reserved for describing a uniquely interpersonal activity seems appropriately to characterize what goes on between people and certain machines as well. Lucy Suchman, Plans and Situated Actions The communication between user and the system [Dix et al., 1998] Direct manipulation and instantaneous change [Becker et al., 1987] 7

8 Importance of Interaction The effectiveness of information visualization hinges on two things: its ability to clearly l and accurately represent information and our ability to interact with it to figure out what the information means. S. Few, Now You See It, p. 55 8

12 Question? Critique and improvement to the interactions (selection)? 12

13 Overview? Comparison, trends? Sorting? Potential Ones 13

14 Taxonomy of Interactions Interaction ti Types by Dix and Ellis (AVI 98) Highlighting and focus Accessing extra info drill down and hyperlinks Overview and context zooming and fisheyes Same representation, changing parameters Linking representations temporal fusion 14

15 Taxonomy of Interactions Taxonomy by D. Keim (TVCG 02): Projection Filtering Zooming Distortion Linking and brushing 15

16 Taxonomy of Interactions Taxonomy by Ward, Grinstein, i Keim (2010) Operator navigation, selection, manipulation, distortion, filtering Space of interaction screen, data value, data structure, attribute, object, visualization i structure Parameters of the interaction operator focus, extents, transformation, blender 16

17 Taxonomy of Interactions Taxonomy from Few s book (Now you see it): Comparing Sorting Adding variables Filtering Highlighting Aggregating Re-expressing Re-visualizing Zooming and panning Re-scaling Accessing details on demandd Annotating Bookmarking 17

27 Any problems with assignment II? 27

28 Task: visualization design Assignment II Design only one new and/or useful and/or interactive visualization over one data set. Your visualization can contain multiple views You can use Photoshop, Adobe Illustrator, Microsoft Paint, Visio,..., or even draw by hand if only the pictures are readable Must have at least one class of target users One clear user task At least one useful interaction What to hand in (in English) A maximum of 5 pictures of the visualization A text description of the data set, target user, user task, visual design/encoding and interactions of your visualization (< 1000 words, including captions) 28

29 Prohibit Registration Too many users in the wiki Wiki Page Assignment Protection You can see but can not edit assignment page after the deadline You can still hand in your homework after the deadline If your assignment is finished and don t need to be modified, Write ultimate edition at the bottom of your assignment page. 29
