Pattern-Driven Navigation in 2D Multiscale Visualizations with Scalable Insets

Scalable Insets is a novel technique for pattern-guided navigation in multiscale visualizations such as geographics maps, gigapixel images, or large matrices like genome interaction maps.

These slides are from my paper talk at IEEE VIS InfoVis 2019.

  3. Clustering:
 projected distance and area in pixel space Stability:
 merge

    and split points differ
 avoid abrupt changes INSET GROUPING
  4. 1. User study: Performance comparison in
 frequency estimation, pattern search,

    and pattern comparison on gigapixel images Participants: 18 Techniques: Results: · faster pattern search
 · more accurate pattern comparison
 · little overhead for frequency estimation EVALUATION
  5. 6 domain experts: free exploration + think aloud Easy-to-learn and

    useful: picked up in ~1min Inner placement:
 guided navigation Outer placement:
 pattern search
 & comparisons 2. USER STUDY
