Summary
Category
Interaction
Context
The display consists of an Overview and Detail.
Problem
How to allow the user to navigate the data space via the overview.
Forces
- A simple mechanism for altering the contents of the detailed view.
- Clear indication of item(s) being viewed in detail. This may include both the size and location for continuous data.
Solution
Place a moveable location indicator within the overview.
There should be a visual location indicator in the overview. Often this is simply a rectangle that represents both the location and area of the dataset being viewed. The user can then click and drag this indicator to the desired location and the contents of the detailed view should be updated accordingly. Similarly if the contents of the detailed view can be altered by some other means e.g. scrollbars, then the location indicator in the overview should be moved to reflect this change. In this way the location indicator and the detailed view are kept in sync. Whilst dragging the indicator the detailed view may be continuously updated (Smooth Transitions). Alternatively the detailed view may only update when the mouse button is released, in which case Teleportation is often an option.
