Abstract
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.
