SpiraClock
SpiraClock is a visualization technique using an analog clock. It is used as a non-intrusive addition to regular calenders and timetables and is primarily used to display nearby events.
The basic concept of SpiraClock is to create a time-management device that is less intrusive (no alerts or pop-ups) and more intuitive (using a regular analog clock) than existing calenders. For this purpose a spiral, representing the near future (usually the next hours), is added to a regular clock. Upcoming events are visualized as colored blocks within the spiral. Events occurring within the next hour are displayed on the outermost branch of the spiral, more distant events are displayed closer to the center of the spiral. Past events fade out as the minute hand of the clock passes them. Different colors, transparency and tool-tips can each be used to add additional information to the events.

- Example questions (which this visualization solves)
Target Group
- Office workers usually sit in front of their PC most of the time and already use it for managing their calendars and timetables. They are therefore already accustomed to the concept of using a computer for time-management and could easily add the SpiraClock to their timekeeping devices.
- Students: SpiraClock is especially useful for managing events with short durations that the user needs to be reminded of only close to the beginning of the event. Students can therefore use SpiraClock to keep track of their lectures, etc. Additionally students are more likely to try out and accept this new concept of timekeeping.
- Anyone using a computer clock as their primary clock can also use SpiraClock, as it only enhances the capabilities of a standard analog clock by the discussed features. Users therefore simply add additional functionality to a program they already use.
