  1. Measuring Insight Into Multi-dimensional Data from a Combination of a Scatterplot Matrix and a HyperSlice Visualization André Calero Valdez, Sascha Gebhardt, Torsten W. Kuhlen, and Martina Ziefle

  2. Industrie 4.0 The Internet of Things and Production Pervasive digitalization Integrated cyber-physical systems - Improved capacity utilization - Improved cost-effectiveness Foster innovation Multi-Dimensional Insights André Calero Valdez DHM - HCII 2017

  3. Challenges in Industrie 4.0 What will we have to adapt to? Transition in engineering work - Self-optimizing, individualized, integrated processes - Regulatory and monitoring tasks Challenges in - Managing knowledge - Sharing responsibility - Dealing with complexity Multi-Dimensional Insights André Calero Valdez DHM - HCII 2017

  4. Complexity Multi-Dimensional Data • How can users understand and manage multi-dimensional data? • One Approach: Visualization • Hyperslicing, Star-coordinates, Chernoff-Faces, etc. Multi-Dimensional Insights André Calero Valdez DHM - HCII 2017

  5. How to present multi-dimensional data? • Slicing of Spaces • Volumetric view of 3D-Space • Move the „cutting plane“ in one dimension Multi-Dimensional Insights André Calero Valdez DHM - HCII 2017

  6. But what about higher dimensions? ... and also abstract parameter data?

  7. One Example Application Multi-dimensional Dependencies • Hyperslice Visualization • 2 Visualizations • Scatterplot Matrix • Hyperslice Matrix • Hyperslice • Each slice presents a 2D-plane from a 6-Dimensional Hyperspace • Each Slice presents 3 dimensions • X/Y + Color Multi-Dimensional Insights André Calero Valdez DHM - HCII 2017

  8. Hyper-Slice in Action Multi-Dimensional Insights André Calero Valdez DHM - HCII 2017

  9. User Study Measuring Insights with 16 engineerings students • We assessed fluid and crystal intelligence (KAI-N) • Mental rotation capability (Paper Folding Test) • Computer self-Efficacy (KUT) • 30 minute tutorial in using the software • 60 minutes tests • Measured insights (novel realizations from software and data) • Usability and Understanding • Data contained a 3-Dimensional dependency! Multi-Dimensional Insights André Calero Valdez DHM - HCII 2017

  10. Results Insights correlate with cognitive abilities • Strong influence of mental rotation capabilities • Computer self-efficacy influences Scattterplot insights • Not everyone can derive multi- dimensional insights from our visualization. • Everyone was able to perform optimization task! Multi-Dimensional Insights André Calero Valdez DHM - HCII 2017

  11. Summary Thank you very much for your attention! • We investigated insights from high- dimensional data • Controlled for cognitive abilities • Mental rotation skill is important for generating insights • Optimization task with steepest descent can be performend without insight • Decision Support!! Multi-Dimensional Insights André Calero Valdez DHM - HCII 2017
