Introduction
Time defines our life. Our whole life is based on time. A year consists of 12
months, a month consists of 28-31 days, a day consists of 24 hours and so on. We
(normally) sleep at night and stay awake during the day. Days, months and years pass
by while things are happening.
The question "When happened
what?" is a basic question in our real life. You cannot just tell somebody
"there was an earthquake" without any time declaration. The
earthquake could have happened ten year ago or just last night.
Not only in
real life but also in virtual environment time is a very important factor. When you
save a document, the time of the saving action is saved as well. This time is very
important when you have for example two documents with identical names and you are
looking for the newer one. Only the saved time gives you information about which
document is the newer one.
Within multimedia applications,
time can be important as well. Here too, the question "When happened
what?" is the most important question concerning the time aspect.
Therefore, time is always coupled with a topic. In other words: there is one layer
for each time segment. To keep one's orientation between these layers we need
temporal navigation.
In this unit, we show you some possibilities how temporal navigation can be realised within web pages and interactive 2D maps.
The following interaction part is only an example of a temporal navigation and is about the history of typography. You do not have to read all the text within the example but you should explore the interactive time line.
