Today
• Incorporating Time– Time in Desktop Search– Time in Photo Collections
• Visualizing Time– Time graph searching
• Hochheiser & Shneiderman• Wattenberg
– Complex Serial Data • Carlis & Konstan

Time in Photo Collections
9
UIs for Personal Photo Collections
• Research on personal photo collections shows:– Chronology important– But people and events more important
• Metadata– Useful, but tedious to input– Graham et al. developed effective automated
grouping mechanisms using time

Usability Study
• Compared automated vs manual labeling• Compared timeline vs no timeline
– For search task people were faster with timeline on second exposure only; strong learning effect
– For browsing task, success rate was 14% higher for timeline interface on first exposure
– People did as well on automated grouping as on manual (except for browsing task)
– No overall preference for any of the approaches• But people prefered their manual organization for
browsing

Searching Time Sequence Data
18
Motivation: Standard time plots are very compelling, but can only display a limited amount of data

Idea:
Query the data!

Usability studies
• 24 Computer Science students completed various tasks using different but semantically equivalent input mechanisms:– Timebox queries– Fill-in– Range sliders
21
Study 1
• Fully specified tasks. (“During days 22-23, are there more stocks between 69-119, 59-109, or 49-99”)– Form fill in fastest– Range sliders second.– Timeboxes last.
22
Study 2
• More open-ended tasks.• Compare:
– Timeboxes with graphical output– Forms with graphical output– Forms with tabular output
• No statistically significant difference.
(Were the users already familiar with timeboxes?)
