5. Evaluatie

6. State-of-the-art

• controlled experiment comparing design elements
• widgets, mapping to graphic
• usability evaluation
• controlled experiments comparing several tools
• case studies
• least common
• natural environment
• real tasks
• time consuming
• difficult to replicate and generalize
• also: re-design

17. Paper

18. • aim + target audience
• related work
• data set: origin, characteristics
• visualisatie & interaction + rationale
• technology & code reuse
• lessons learned & conclusion
Structuur

19. Beschrijf niet enkel de visualisatie, maar leg
vooral uit waarom je die visualisatie zo
gemaakt hebt:
• welke alternatieven heb je overwogen?
• waarom heb je die eventueel niet
weerhouden?
• Hoe is het ontwerp geëvolueerd? Waarom?
• Enz.

20. dataset
- origin
- distribution of values
- missing or erroneous values
- size
- API
- …

21. code you’ve re-used:
mention in acknowledgements
or explain in technology section

22. Technology section
- data collection
- data processing
- d3 experiences
- code from elsewhere

23. Related work
- not just same data
- not just web pages
- scientific papers do exist!
- how is your work
similar and different? why?
- Max 1 page (screenshots included) !

24. Suggested Exercise-per-team;
Scholar session:
find 5-15 relevant papers…
- what did you search on?
- what did you find?
- why or how is this relevant?
See what you can find in 15 to 30 minutes ;)

25. Ook nog…

26. • geen chronologisch verhaal!
• als je problemen hebt opgelost, geef dan concrete
voorbeelden!
• niet: ‘to prevent giving a false impression to the
user’
• […]: kan je niet zo maar beweren
• page limit: 8 pages, including everything!

27. • Onderbouw nodig!
• “However while most people know the two World
Wars that happened, they don’t know a lot about
conflicts that happened later or those that were
shorter in time”
is dat wel zo…

28. • Geen vage statements
• “The data speaks for itself and redundant non-
data-ink was removed to keep the visualization
clean and simple”

30. • Deadline: Zondag 5 juni 0u00!
(insturen via email naar joris.klerkx@cs.kuleuven.be)
• Misschien later indienen bij workshop of conferentie…
• Afsluitend gesprek nodig tijdens examenperiode?

31. Finale demo
9 mei stipt om 16u

32. - 10+7 min/group
- tonen ipv vertellen
- rationale! (alternatieven…)
- demo
- lessons learned

33. Show & tell sessie
Positief?
