| == Technique == | | === Aufgabe 3 === |
| We are interested in visualisation techniques that are especially well suited for data with an important time-dimension. Thus our choice would be Perspective Wall or Theme River.

| We are not sure yet, which one is suited better, so we would like to regard both, as long as possible.
| | *'''[[Teaching:TUW - UE InfoVis WS 2006/07 - Gruppe 08 - Aufgabe 3 - Prototype|Prototype]]''' |
| At the moment Perspective Wall seems like the better choice as important elements of it (bifocal display with distortion on the off-center viewports) are better suited for prefuse.

| === Data ===
| |
| ''How can we describe the usage of a technique without defining the data we want to present?'' | |
| | |
| Tagebuch/Diary - person meeting people, being at places - in time.
| |
| The data will most likely be available in tabular form with the two most important dimensions being time and people.
| |
| | |
| === Visual Mapping ===
| |
| Basic dimension is time. It is mapped to the horizontal axis.
| |
| | |
| Other dimensions are places and people.
| |
| As long as one person is examined, the ribbon could be sliced vertically,
| |
| according to places, where the person is, as one person can be only on one place at one time.
| |
| | |
| Other persons, ie persons the examined person meets or mentions, should be displayed in separate, parallel horizontal slices (in Perspective Wall).
| |
| This makes the gist of the data (who met where when?) visible at one glance.
| |
| | |
| === Interaction ===
| |
| * Zooming the time axis (from whole regarded data set to one day)
| |
| * Navigation to special date (but also eg just year)
| |
| * Query on places and persons visualized either as restriction (filtering) or through highlighting.
