12 There is no right nor wrong, only different requirements Inspiring and creative visualizations are good as long as we avoid nonsense designs There exist different shades of well designed visualizations.

13 Informed Visualizations Empiricism Evidence Science (Visualization&Human Factors) Best practice Inspired by examples

14 Validation of Goals Experience (Qualitative) Comprehension (Quantitative) User studies, Experiments, Tests, Observations, Interviews

15 Experience Comprehension Collaborative spatial problem solving Project AQUA Designers tend to overestimate technology

16 Experience Comprehension Task Experimental setup Designers tend to overestimate technology User response (performance)

17 Experience Comprehension Augmented Reality is currently hot in BIM and SmartCities Own development and validation Studies at HiG/UU High expectations and biased perception

18 Experience Comprehension Overestimation of technology and own performance

19 Informed Visualizations Empiricism Evidence Science (Visualization&Human Factors) Best practice Inspired by examples

20 Example Use of color Color theories and color perception are well studied is fundamental to visualization is one of only few visual variables is often misused An experiment

21 Visualize

22 Visualize

23 Visualize

24 Example Use of color Background Target trial #1 Target trial #2 Target trial #3 Just noticeable difference (JND)

25 A design case from process industry Lime Kiln one of many critical process components Collapsed rotary kiln due to overheating as a result of insulation defects

26 A design case from process industry A process operator s work A lot of things to keep track of Most of the time little action

27 A design case from process industry The task: Change detection The visualization: Current state Manual transitions Issues with colors

28 Pre-studies Color mapping designs for JND tasks Graphical mappings 2D map 3D map 3D cylindrical

29 Validation study in the field Degrees C Temperature increase 40s Interval

30 Detection Time [s] Some results Detection Times (Median) Between Teams D Map 3D Field 3D Tube B-Team F-Team

31 Conclusion Visualisera rätt Empiricism Evidence Science (Visualization&Human Factors) Visualisera fritt Best practice Inspired by examples

32 Conclusion Scientific Community Visualization Experts Empiricism Evidence Domain Experts Science (Visualization&Human Factors) Media Society Best practice Inspired by examples Universities Companies/Organizations
