User Study Selection Layering
- Within-Subjects Design
- 18 users x
- 2 tasks Selection, Layering x
- 3 tools Tumbler, Splatter, Palette x
- 2 scene complexities low, high
- Palette with no scrollbar.

Observations
- Familiarity with scene favored T S
- Palette used in concert with scene
- Surprise splatter was good for layering
- Participants thought in terms of pairs of objects
- Activation can be onerous
- Tumbler (15 sec)
- Splatter (0.5 sec)
11
User Study Jigsaw Puzzle
- Ecological task
- Observational study
- 10 users x 3 tools x 2 puzzles
2x normal speed
12
Observations
- Users opinions shifted
- Splatter efficient, sensible, satisfying
- Tumbler intuitive for layering tasks
- Almost no x-y adjustments with this tool
- Palette required thinking
13
Lessons learned
- All tools valuable for users
- Could complement each other well
- Use the best tool for the job
- Make palette local
- Automate Tumblers activation
- Add to Splatter at-a-glance z-information
14
Tumbler Splatter
- In Summary
- Proposed new tools
- Executed studies showing tools viability and
potential co-existence - Future work
- Iterate and improve designs
- Add support for groups and hierarchies

User Study Selection Layering
- Goals
- Identify tools strengths weaknesses
- Gather usability preliminary contrast data
- Hypotheses
- Splatter good for quick selection
- Tumbler good for (quick) layer manipulations
- Palette is familiar, simple to use
