OLIVE: Temporal



Throughout the history of computer information retrieval, timelines have been represented as simple lists. However, this approach can be improved through the use of techniques which take into account other information which can be gleaned from this data. The use of temporal information visualization has two fundamental qualities that distinguish it from standard simple lists: (1) the fact that temporal events can be either simultaneous or overlapping and (2) the underlying multiple scales of temporal data which require both precise and gross measurements (ranging from one second to multiple centuries).

Some examples of temporal visualization include animations, project timelines, lifelong timelines, video representation, and video manipulation. Each of these examples takes data that is modified over time and presents views that can be quickly and dynamically altered based upon the specific time frame and information that is desired for viewing. This allows the user to have greater control over the information than was presented in a typical static rendering of the data. Specifically, the user can manipulate time and change the temporal order of the information being viewed so they can find new patterns and/or visions.
