Calendar applications for small handheld devices such as
PDAs are growing in popularity. This led us to develop
FishCal, a novel calendar interface for PDAs. It supports
users in performing planning and analysis tasks by using a
fisheye representation of dates coupled with compact
overviews, user control over the visible time period, and
integrated search. This enables users to see overviews and
to easily navigate the calendar structure, and to discover
patterns and outliers.
FishCal was evaluated in a benchmark usability study
comparing it to Microsoft's Pocket PC 2002(TM) calendar.
Eleven users performed complex tasks significantly faster
and completed them more often with FishCal. Task by task
user satisfaction data showed a significant advantage for
FishCal as well. A number of usability issues were
identified to aid in the iterative refinement of FishCal.
