Evaluation• Munzner’s nested model for visualization design and validation
Munzner: "A nested model for visualization design and validation."Visualization and Computer Graphics, IEEE Transactions on 15.6 (2009): 921-928.
7
Evaluation• Isenberg et al.: 10 years of VIS paper evaluations
• Trend: more evaluations involving participants
Isenberg et al.: "A systematic review on the practice of evaluating visualization.“IEEE Transactions on Visualization and Computer Graphics, 19.12 (2013): 2818-2827.
9
Performance Evaluation• Measurable quantities:
• Timings: rendering, preprocessing, framerates
• Compared to similar methods
• On the same data (OSIRIX, AIM@SHAPE)
10
Case Study• Apply method to clinical data
• What is shown/new insights
• Should be done by domain experts, otherwise usage scenarios
12
Which Users?• Domain experts, students in the field
• People in the lab, students
• Depending on task: random people on the street

MOOC Deployment• Massive Open Online Course (MOOC) on human anatomy via
Coursera: • Over 14000 active learners worldwide• https://www.coursera.org/learn/anatomy
17
Online Evaluation• Large scale user study
• Survey:• Statements with Likert scale responses• Open questions• Linked to Coursera user profiles
User experience
User performance

Illustrative Multi-volume Rendering for PET/CT Scans
Lawonn et al.: "Illustrative multi-volume rendering for PET/CT scans.“ Proceedings of the Eurographics Workshop on Visual Computing for Biology and Medicine 2015
25
Conclusion• Evaluation methods for medical visualization:
• Performance• Case study• User study
• Medvis Challenge?
