These models generally comprise a high number of parameters, which makes it hard to identify the values that best reproduce the empirical data. Furthermore, different combinations of parameters may achieve a good fit, which renders an automatic solution ill-suited to the task. A human expert is required to make the final decisions about the optimal parameter values. We present VisEPS (Visual Explorer of Parameter Spaces), a framework for visually analyzing the effects of a very large set of parameters, with the aim of fitting a geographically explicit networked model to data obtained during the COVID-19 pandemic. We use a networked extension of a susceptible-infected-recovered (SIR) model to reproduce the epidemic dynamics in the city of Buenos Aires and its neighboring interconnected districts. We overlay binned scatterplots on a map, which facilitates the visual identification of each district and its connections. To further explore the model’s performance against data, additional views, such as parallel coordinates and histograms, along with drill-down mechanisms, have been incorporated. Finally, a use case is described in which the level of connectivity between districts is included in the analysis. The identification of suitable parameter ranges is facilitated by an iterative and incremental process, whereby new sets of simulations are incrementally requested, guided by interactive visual inspections. This permits the exploration of a parameter space that would otherwise be impossible to fully explore.", "authors_et_al": false, "substitute": null, "main_image": null, "sync_repositum_override": null, "repositum_presentation_id": "20.500.12708/225781", "authors": [ 5537, 235, 5538, 166, 5539 ], "date_from": "2025-07-03", "date_to": "2025-07-04", "doi": "10.1007/s12650-025-01093-2", "event": "The 2nd Japan Visualization Symposium (JapanVis 2025)", "issn": "1875-8975", "journal": "Journal of Visualization", "lecturer": [ 235 ], "location": "Tokyo", "pages": "15", "publisher": "SPRINGER", "research_areas": [], "keywords": [ "Interactive visual exploration", "Networked simulation models", "Scalable visual parameter tuning", "Visual model parameter fitting" ], "weblinks": [], "files": [], "projects_workgroups": [], "url": "https://www.cg.tuwien.ac.at/research/publications/2025/lanzarotti-2025-viseps/", "__class": "Publication" }, { "id": "fernandez-2022-ergoexplorer", "type_id": "journalpaper_notalk", "tu_id": null, "repositum_id": "20.500.12708/175616", "title": "ErgoExplorer: Interactive Ergonomic Risk Assessment from Video Collections", "date": "2022-10-05", "abstract": "Ergonomic risk assessment is now, due to an increased awareness, carried out more often than in the past.

These views also incorporate domain-specific score tables to guarantee an easy adoption\nby domain experts. All views are integrated into ErgoExplorer, which relies on coordinated multiple views to facilitate analysis through\ninteraction. ErgoExplorer makes it possible for the first time to examine complex relationships between risk assessments of individual\nbody parts over long sessions that span multiple operations.

It has been demonstrated that the\ndrawbacks of radial charts outweigh the benefits of this natural mapping. Visualization of daily patterns, as a special case, has not been systematically evaluated using radial charts. In contrast to yearly or weekly recurrent trends, the analysis of daily patterns on a radial chart may benefit from our trained skill on reading radial clocks that are ubiquitous in our culture. In a crowd-sourced experiment with 92 non-expert users, we evaluated the accuracy, efficiency, and subjective ratings of radial and linear charts for visualizing daily traffic accident patterns. We systematically compared juxtaposed 12-hours variants and single 24-hours variants for both layouts in four low-level tasks and one high-level interpretation task. Our results show that over all tasks, the most elementary 24-hours linear bar chart is most accurate and efficient and is also preferred by the users.

Advances in simulation technology and the ability to run multiple simulations with different sets of parameters pose new challenges for analysis techniques.

Instead, a single data point contains scalars, time series, and other types of mappings. Such a data model is common in many domains. Interactive visual analysis utilizes a tight feedback loop of computation/visualization and user interaction to facilitate knowledge discovery in complex datasets.\n\nOur research extends the visual analysis technology to challenging heterogeneous data, in particular to a combination of multivariate data and more complex data types, such as functions, for example. Furthermore, we focus on developing a structured model for interactive visual analysis which supports a synergetic combination\nof user interaction and computational analysis.\n\nThe concept of height surfaces and function graphs is a proven and well developed mechanism for the analysis of a single mapping.

They try to reconstruct the tectonic settings where these rocks were formed and the history of events that affected them through the geological time. The spinel group minerals provide useful information regarding the geological environment in which the host rocks were formed. They constitute excellent indicators of geological environments (tectonic settings) and are of invaluable help in the search for mineral deposits of economic interest. The current workflow requires the scientists to work with different applications to analyze spine data. They do use specific diagrams, but these are usually not interactive. The current workflow hinders domain experts to fully exploit the potentials of tediously and expensively collected data. In this paper, we introduce the Spinel Explorer-an interactive visual analysis application for spinel group minerals. The design of the Spinel Explorer and of the newly introduced interactions is a result of a careful study of geologists' tasks. The Spinel Explorer includes most of the diagrams commonly used for analyzing spinel group minerals, including 2D binary plots, ternary plots, and 3D Spinel prism plots. Besides specific plots, conventional information visualization views are also integrated in the Spinel Explorer. All views are interactive and linked. The Spinel Explorer supports conventional statistics commonly used in spinel minerals exploration. The statistics views and different data derivation techniques are fully integrated in the system. Besides the Spinel Explorer as newly proposed interactive exploration system, we also describe the identified analysis tasks, and propose a new workflow. We evaluate the Spinel Explorer using real-life data from two locations in Argentina: the Frontal Cordillera in Central Andes and Patagonia. We describe the new findings of the geologists which would have been much more difficult to achieve using the cur- ent workflow only.

A simulation ensemble is a collection of simulation runs of the same simulation model using different sets of control parameters. Complex engineering systems have very large parameter spaces so a nai?ve sampling can result in prohibitively large simulation ensembles. Interactive steering of simulation ensembles provides the means to select relevant points in a multi-dimensional parameter space (design of experiment). Interactive steering efficiently reduces the number of simulation runs needed by coupling simulation and visualization and allowing a user to request new simulations on the fly. As system complexity grows, a pure interactive solution is not always sufficient. The new approach of hybrid steering combines interactive visual steering with automatic optimization. Hybrid steering allows a domain expert to interactively (in a visualization) select data points in an iterative manner, approximate the values in a continuous region of the simulation space (by regression) and automatically find the “best” points in this continuous region based on the specified constraints and objectives (by optimization). We argue that with the full spectrum of optimization options, the steering process can be improved substantially. We describe an integrated system consisting of a simulation, a visualization, and an optimization component. We also describe typical tasks and propose an interactive analysis workflow for complex engineering systems.

In this paper we describe a successful realization of a tightly coupled steering loop, integrating\r\nnew simulation technology and interactive visual analysis in a prototyping environment for automotive industry system design. Due\r\nto increasing pressure on car manufacturers to meet new emission regulations, to improve efficiency, and to reduce noise, both simulation\r\nand visualization are pushed to their limits. Automotive system components, such as the powertrain system or the injection\r\nsystem, have an increasing number of parameters, and new design approaches are required. It is no longer possible to optimize\r\nsuch a system solely based on experience or forward optimization. By coupling interactive visualization with the simulation back-end\r\n(computational steering), it is now possible to quickly prototype a new system, starting from a non-optimized initial prototype and the\r\ncorresponding simulation model. The prototyping continues through the refinement of the simulation model, of the simulation parameters\r\nand through trial-and-error attempts to an optimized solution. The ability to early see the first results from a multidimensional\r\nsimulation space — thousands of simulations are run for a multidimensional variety of input parameters — and to quickly go back\r\ninto the simulation and request more runs in particular parameter regions of interest significantly improves the prototyping process\r\nand provides a deeper understanding of the system behavior.
