                Overview
• Scalable interface for examining
  connections between two sets of
  hierarchical data
The Problem
             The Solution(s)
•   Highlight Propagation
•   Auto-Scrolling
•   Coalescing Trees
•   Multi-Select
•   Incremental Search
Highlight Propagation
              Auto-Scrolling
• Auto-scroll map
  – Center mappings on selected element
• Auto-scroll columns within map
  – Map consists of columns of functoids
     • “functoids” is not a word in Word™
• Auto-scroll other schema tree view
  – Animated transition
Auto-Scrolling
Coalescing Trees
Multi-Select
Incremental Search
                        User Study
• 8 very experienced BizTalk users
• 4 Versions
   –   A: Baseline
   –   B: Add highlight propagation
   –   C: Add auto-scroll
   –   D: Add coalescing and search ticks
        • (i.e., everything)
• 6 isomorphic tasks / person / version
• Order controlled by partial Latin Square
Results
Results
                    Results
• Time Trials
  – All significantly faster than baseline
  – Full feature set (D) faster than just highlighting
    (B)
• Satisfaction Survey
  – All preferred over baseline
  – No significant difference between B, C, D
• However, unanimously preferred D when
  asked directly (people like features!)
               Future Work
• Extend features to editing scenario
• Include features in TreeView control
  – Animated scrolling
  – Coalescing
  – Incremental search with scrollbar ticks
                Discussion
• Does reordering versions even matter when
  they’re incremental improvements?
  – Might get more useful data by separating
    features
• Generalize these ideas to other problems?
