Visualization has been successfully applied to analyse time-dependent data for a long time now. Lately, a number of new approaches have been introduced, promising more effective graphs especially for large datasets and multiparameter data. In this paper, we give an overview on the visualization of time-series data and the available techniques. We provide a taxonomy and discuss general aspects of time-dependent data. After an overview on conventional techniques we discuss techniques for analysing time-dependent multivariate data sets in more detail. After this, we give an overview on dynamic presentation techniques and event-based visualization.
This paper presents an interactive, virmal reality based training environment specifically developed to support training of maintenance procedures of complex technical equipment. The architecture of the system will briefly be described. Moreover, the paper explains the different training modes that allow for adapting the training environment to the trainee's knowledge and determine the level of interactivity. A short glimpse is given to the scenario author's work. Finally, an example scenario will be described to demonstrate a practical application of the training environment.
Information visualization exploits the phenomenal abilities of human perception to identify structures by presenting abstract data visually, allowing an intuitive exploration of data to get insight, to draw conclusions and to interact directly with the data. The specification, analysis and evaluation of complex models and simulated model data can benefit 60m information visualition techniques by obtaining visual support for different tasks. This paper presents an approach that combines modelling and visualization functionality to support the modelling process. Based on this general approach, we have developed and implemented a framework that allows to combine a variety of models with statistical and analytical operators as well as with visualization methods. We present several examples in the context of climate modelling.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
