About Datelens

Calendar applications for small handheld devices such as PDAs are growing in popularity. This led us to develop DateLens, a novel calendar interface that supports not only PDAs, but a range of devices, from desktop computers to Tablet PCs. 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 timer period, and integrated search. This enables users to see overviews, easily navigate the calendar structure, and discover patterns and outliers. Moreover, DateLens takes advantage of each device, running quickly on PDAs and supporting ink on Tablet PCs.

Note: We are not currently supporting or adding new features to DateLens
