“…Dynamic querying is defined as "…the interactive user control of visual query parameters that generate rapid (100 ms update) animated visual display of database search results" [1]. Although database retrieval was the original target application, the interactive visualization technique dynamic queries has since been applied to many other domains including data-mining [1][2][3] and simulation [4,5].…”

“…Whilst dynamic query is perfectly feasible means of interacting with pre-computed datasets [4,5], generating ad hoc results in real-time is not possible using a typical simulation model, as complex calculations need to be applied to the state over many iterations. In this paper the authors propose that the concept of query previews [6] can be extended to the task of exploring the parameter space of a simulation model.…”

“…Temporal exploration of simulations using dynamic queries has already been explored by Bosch [5]. They used dynamic query controls to enable the user to cycle through the progression of a run of a SimOS machine simulation of the Argus parallel rendering library and also to focus in on particular attributes of the recorded output.…”

This paper shows how model simplification, by replacing iterative steps with unitary predictive equations, can enable dynamic interaction with a complex simulation process. Model previews extend the techniques of dynamic querying and query previews into the context of ad hoc simulation model exploration. A case study is presented within the domain of counter-current chromatography. The relatively novel method of insight evaluation was applied, given the exploratory nature of the task. The evaluation data show that the trade-off in accuracy is far outweighed by benefits of dynamic interaction.The number of insights gained using the enhanced interactive version of the computer model was more than six times higher than the number of insights gained using the basic version of the model. There was also a trend for dynamic interaction to facilitate insights of greater domain importance.2

Abstract. To investigate how participants in peer production systems allocate their time, we examine editing activity on Wikipedia, the well-known online encyclopedia. To analyze the huge edit histories of the site's administrators we introduce a visualization technique, the chromogram, that can display very long textual sequences through a simple color coding scheme. Using chromograms we describe a set of characteristic editing patterns. In addition to confirming known patterns, such reacting to vandalism events, we identify a distinct class of organized systematic activities. We discuss how both reactive and systematic strategies shed light on self-allocation of effort in Wikipedia, and how they may pertain to other peer-production systems.

“…CPROF [20][21] and VTUNE [19] are two examples of programs that display information such as cache misses or branch mispredictions for specific segments of code. RIVET [22][23][24] is a powerful display environment developed at the Stanford Computer Graphics Laboratory. The tool provides a very detailed time line view to identify problem areas.…”
