Abstract

We present and discuss the results of a two-year qualitative analysis of images published in IEEE Visualization (VIS) papers. Specifically, we derive a typology of 13 visualization image types, coded to distinguish visual designs and several image characteristics. The categorization process required much more time and was more difficult than we anticipated. The resulting typology and image analysis may serve a number of purposes: to study the evolution of the community and its research output over time, to facilitate the categorization of visualization images for the purpose of research or teaching, to identify visual design styles, or to enable progress towards standardization in visualization. In addition to the typology and image characterization, we provide a dataset of 6,833 tagged images and an online tool that can be used to explore and analyze the large set of tagged images. The tool and data set enable a close examination of the diverse visualizations used and how they are published and communicated in our community.

Abstract

International audience; We discuss a design space for combining, linking, and jointly presenting 3D spatial data together with related abstract data, the latter typically mapped to 2D space. Even though guidelines exist for creating linked 2D views that help designers and inspire researchers, they typically do not encompass 3D spatial data representations. We thus first reviewed the existing visualization literature and explored linking patterns in existing systems. We then extracted the dimensions of how these tools combine 2D and 3D data by their semantic relationships, display environment, placement, and the linking methods between them.

Abstract

International audience; We present Multiscale Unfolding, an interactive technique for illustratively visualizing multiple hierarchical scales of DNA in a single view, showing the genome at different scales and demonstrating how one scale spatially folds into the next. The DNA's extremely long sequential structure---arranged differently on several distinct scale levels---is often lost in traditional 3D depictions, mainly due to its multiple levels of dense spatial packing and the resulting occlusion. Furthermore, interactive exploration of this complex structure is cumbersome, requiring visibility management like cutaways. In contrast to existing temporally controlled multiscale data exploration, we allow viewers to always see and interact with any of the involved scales. For this purpose we separate the depiction into constant-scale and scale transition zones. Constant-scale zones maintain a single-scale representation, while still linearly unfolding the DNA. Inspired by illustration, scale transition zones connect adjacent constant-scale zones via level unfolding, scaling, and transparency. We thus represent the spatial structure of the whole DNA macro-molecule, maintain its local organizational characteristics, linearize its higher-level organization, and use spatially controlled, understandable interpolation between neighboring scales. We also contribute interaction techniques that provide viewers with a coarse-to-fine control for navigating within our all-scales-in-one-view representations and visual aids to illustrate the size differences. Overall, Multiscale Unfolding allows viewers to grasp the DNA's structural composition from chromosomes to the atoms, with increasing levels of "unfoldedness," and can be applied in data-driven illustration and communication.

Abstract

International audience; We report on a controlled user study in which we investigated and compared three selection techniques in discovering and traversing 3D objects in densely packed environments. We apply this to cell division history marking as required by plant biologists who study the development of embryos, for whom existing selection techniques do not work due to the occlusion and tight packing of the cells to be selected. We specifically compared a list-based technique with an additional 3D view, a 3D selection technique that relies on an exploded view, and a combination of both techniques. Our results indicate that the combination was most preferred. List selection has advantages for traversing cells, while we did not find differences for surface cells. Our participants appreciated the combination because it supports discovering 3D objects with the 3D explosion technique while using the lists to traverse 3D cells.

Abstract

International audience; We investigate the use of subjective views for co-located collab-orative Augmented Reality (AR) environments for 3D scientific visualization, i. e., views that are perceived differently per user, no matter their viewpoints. AR technology allows collaborators to benefit seamlessly from both their visualization and social spaces. However, those same collaborators might have different roles and expertise levels, which might need one visualization rather than another. When using one active screen per user, an AR collaborative system can render the scene with different parameters per user, yet with the same spatial reference. As 3D visualization often relies on multiple data layers, heavy filtering, and several transfer functions, the resulting multi-view representations may no longer all be shown or can lead to conflicts in the users' social space where collaborate with others. Here we propose multiple designs to overcome this issue.

Abstract

International audience; We discuss a 3D volume selection technique supported by Augmented Reality (AR) using both a tangible multi-touch device and an AR Head-Mounted Display (AR-HMD). While the HMD stereo-scopically renders the dataset, the tablet allows the user to draw a lasso that can be extruded using the tablet's relative or absolute position and orientation. This interaction is inspired by the original Tangible Brush technique. We aim, with this setup, to understand the implications of a tangible device where its absolute position now has meaning in the user's output space compared to traditional implementations where only the relative movements are captured.

Abstract

International audience; We provide an interactive system for biologists to assist them in analyzing the development of plant embryos. With this tool they could reconstruct the development history of an embryo, based on a single segmented 3D image from the confocal microscopy. Compared to their traditional manual procedure, our approach supports reasoning about the development of both wild type and mutant plant embryos. For this purpose we use reconstructed surface models of the individual cells, allow the researchers to interactively assign sister cells per development cycle, and complete an inheritance tree. In addition to this manual assignment, we also add an automatic assignment based on the area of the cell interfaces (shared surfaces between cells). For the interactive assignment or correction, we explore different selection strategies of the cells in the dense dataset.

Abstract

We present our vision and steps toward implementing a collaborative 3D data analysis tool based on wearable Augmented Reality Head-Mounted Display (AR-HMD). We envision a hybrid environment which combines such AR-HMD devices with multi-touch devices to allow multiple collaborators to visualize and jointly discuss volumetric datasets. The multi-touch devices permit users to manipulate the datasets' states, either publicly or privately, while also proposing means for 2D input for, e. g., drawing annotations. The headsets allow each user to visualize the dataset in physically correct perspective stereoscopy, either in public or in their private space. The public space is viewed by all, with modifications shared in real-time. The private space allows each user to investigate the same dataset with their own preferences, for instance, with a different clipping range. The user can later decide to merge their private space with the public one or cancel the changes., EuroVis 2019 - Posters, Posters, 21, 23, Mickael Sereno, Lonni Besançon, and Tobias Isenberg, CCS Concepts: Human-centered computing --> Scientific visualization; Interaction techniques; Synchronous editors

Abstract

International audience; The process of data exploration is becoming an essential part of today's scientific workflows. A large number of immersive visualization environments are being explored to help researchers and experts to better understand the data and to offer intuitive interaction. Despite these benefits, shown by prior research, it is still uncommon to find them being applied to realistic scientific workflows. We argue that immersive visualization techniques will not be adopted until they can be easily integrated in the workflow of domain experts, and that specific efforts should be made to help the integration of novel and immersive visualization techniques with classically used software.

Abstract

International audience; In this student project, we explore how situated visualization of office noise can help desk workers become more aware of the noise they produce and are exposed to. More and more people spend a significant amount of time working in offices. Office work has been associated with a number of health issues and, in particular, noise has been identified as a cause of health concerns; including the inability to concentrate and elevated stress. We contribute a beginning design study for a situated visualization of office noise. Specifically, we ran a design workshop session with office workers to elicit design requirements. From the workshop we then conducted a larger online survey on noise exposure in office spaces. From the results of the workshop and the survey, we finally derived first design mockups on which we also report here.

Abstract

To appear; International audience; We explore the concept of abstraction as it is used in visualization, with the ultimate goal of understanding and formally defining it. Researchers so far have used the concept of abstraction largely by intuition without a precise meaning. This lack of specificity left questions on the characteristics of abstraction, its variants, its control, or its ultimate potential for visualization and, in particular, illustrative visualization mostly unanswered. In this paper we thus provide a first formalization of the abstraction concept and discuss how this formalization affects the application of abstraction in a variety of visualization scenarios. Based on this discussion, we derive a number of open questions still waiting to be answered, thus formulating a research agenda for the use of abstraction for the visual representation and exploration of data. This paper, therefore, is intended to provide a contribution to the discussion of the theoretical foundations of our field, rather than attempting to provide a completed and final theory.

Abstract

National audience; We present a pressure-augmented tactile 3D data exploration technique specifically designed for small devices. Our work is motivated by the need to support interactive visualization beyond traditional desktop workstations, especially on small portable devices. We evaluate our approach by comparing it with traditional 3D-RST (rotation, scaling, translation) using a docking task. We show that our technique increases the precision of interaction, with only little impact on interaction speed.

Abstract

To appear; International audience; In this article we survey illustrative rendering techniques for 3D surface models. We first discuss the field of illustrative visualization in general and provide a new definition for this sub-area of visualization. For the remainder of the survey we then focus on surface-based models. We start by briefly summarizing the differential geometry fundamental to many approaches and discuss additional general requirements for the underlying models and the methods' implementations. We then provide an overview of low-level illustrative rendering techniques including sparse lines, stippling and hatching, and illustrative shading, connecting each of them to practical examples of visualization applications. We also mention evaluation approaches and list various application fields, before we close with a discussion of the state of the art and future work.

Abstract

International audience; We present a pressure-augmented tactile interaction technique to improve 3D object/view manipulation tasks on mobile devices. Existing tactile techniques for mobile data exploration either make use of up to four fingers to control all the needed degrees of freedom (DOF) for 3D manipulation or simultaneously adjust multiple DOF together to reduce the number of fingers needed for interaction. Yet the small display size of mobile devices limits the number of fingers that should simultaneously be used. Controlling each DOF for 3D data exploration separately, however, gives users more control. We address this contradiction by combining tactile and pressure input. We thus use pressure to intuitively switch between different tactile interaction modes. In this extended abstract we describe our interaction design as well as our rationale for the input mappings.

Abstract

TEC - Travaux en Cours; International audience; We present the design of a 6-DOF tangible controller for 3D spatial data selection. Such selection is a fundamental task in scientific visualization : it is performed prior to many other interactions. Many datasets are defined in 3D space, yet selection is often performed based on 2D input. While 2D-input-based selection may be efficient for datasets with explicit shapes, it is less efficient for data without such objects or structures. We then address this issue by combining 2D tactile with 3D tangible input to perform 3D selection in volumetric datasets; Nous présentons le design et l'implémentation d'une technique offrant 6 degrés de liberté pour la sélection spatiale de données en 3D. Cette sélection est une tâche primordiale pour la visualisation scientifique car elle est effectué en amont d'autres tâches d'analyse et d'interaction. Une grande majorité des jeux de données est définie en 3D tandis que la sélection de sous-ensembles est, la plupart du temps, basée sur une saisie 2D. La sélection basée sur une saisie 2D est efficace pour des cas où les sous-ensembles à sélectionner ont des formes explicites, mais l'est beaucoup moins lorsque la donnée ne présente pas ces artéfacts. Nous proposons donc de nous intéresser à ce problème en combinant une saisie tactile 2D et une saisie tangible 3D afin de permettre la sélection de sous-ensemble 3D dans les jeux de données volumétriques.

Abstract

National audience; We present the design and evaluation of an interface that combines tactile and tangible paradigms for 3D visualization. While studies have demonstrated that both tactile and tangible input can be efficient for a subset of 3D manipulation tasks, we reflect on combinations of the two complementary input types. Based on a field study and follow-up interviews, we present a prototypical application of hybrid tactile/tangible interaction techniques for fluid dynamics data visualization using a portable, position-aware device. We briefly report on the evaluation of our approach with qualitative feedback.

Abstract

International audience; I argue that we need to increase our consideration of the interaction that is possible and/or needed for the NPAR algorithms we develop. Depending on the application domain of a given algorithmic contribution, different degrees of interaction are required to make it practically useful and, thus, relevant. The spectrum of interactivity ranges from (almost) fully automatic processing to levels of control that are similar to those of traditional tools—some of the approaches even needing to support the full spectrum. Only if these considerations are first-class members of the NPAR development process can we expect others to want to work with our tools and to use them on a regular basis.

Abstract

We evaluate the performance and usability of mouse-based, touch-based, and tangible interaction for manipulating objects in a 3D virtual environment. This comparison is a step toward a better understanding of the limitations and benefits of these existing interaction techniques, with the ultimate goal of facilitating the integration of different 3D data exploration environments into a single interaction continuum. For this purpose we analyze participants' performance in 3D manipulation using a docking task. We measured completion times, docking precision, as well as subjective criteria such as fatigue, workload, and preference. Our results show that the three input modalities provide similar levels of precision but require different interaction times. We also discuss our qualitative observations as well as people's preferences and put our findings into context of the practical application domain of 3D data analysis environments.

Abstract

By design, interactive tabletops and surfaces provide numerous opportunities for data visualization and analysis. In information visualization, scientific visualization, and visual analytics, useful insights primarily emerge from \emph{interactive} data exploration. Nevertheless, interaction research in these domains has largely focused on mouse-based interactions in the past, with little research on how interactive data exploration can benefit from interactive surfaces. These proceedings represent the results of the DEXIS 2015 Workshop on Data Exploration for Interactive Surfaces. It was held in conjunction with the ACM International Conference on Tabletops and Interactive Surfaces (ITS) in Funchal on the island of Madeira, Portugal, on November 15, 2015.

Abstract

International audience; We contribute an in-depth analysis of the characteristics of traditional stippling and relate these to common practices in NPAR stippling techniques as well as to the abilities and limitations of existing printing and display technology. In our work we focus specifically on the properties of stipple dots and consider the dimensions and attributes of pens and paper types used in artistic practice. With our analysis we work toward an understanding of the requirements for digital stippling, with the ultimate goal to provide tools to artists and illustrators that can replicate the stippling process faithfully in the digital domain. From the results of our study we provide a dataset for use in new example-based stippling techniques, derive a taxonomy of characteristics and conditions for the reproduction of stippling, and define future directions of work.

Abstract

Extended version of a short paper at Pacific Graphics 2011 (http://dx.doi.org/10.2312/PE/PG/PG2011short/105-110); We present a flexible illustrative line style model for the visualization of streamline data. Our model partitions view-oriented line strips into parallel bands whose basic visual properties can be controlled independently. We thus extend previous line stylization techniques specifically for visualization purposes by allowing the parametrization of these bands based on the local line data attributes. Moreover, our approach supports emphasis and abstraction by introducing line style transfer functions that map local line attribute values to complete line styles. With a flexible GPU implementation of this line style model we enable the interactive exploration of visual representations of streamlines. We demonstrate the effectiveness of our model by applying it to 3D flow field datasets.

Abstract

International audience; Visualization has shown its ability to produce powerful tools for analyzing, understanding, and communicating data and making it accessible for several different tasks and purposes. Impact of visualization to everyday work and personal lives is demonstrated by many successes stories---such as the increasing prevalence of Tableau, the interactive visualizations produced by the New York Times, or toolkits like VTK/Paraview to name just a few. A large community of casual and professional users are increasingly consuming and producing both interactive and static visualizations.While interactive visualizations move from research into practice at an increasing rate, it still remains an important challenge to find appropriate methods to evaluate their utility and usability. There is a growing need in the community to develop special approaches and metrics for evaluation at all stages of the development life cycle that address specific needs in visualization. This need is reflected, for example, in the increasing number of papers on visualization evaluation---not just at BELIV but also in other venues such as the IEEE VIS conferences and EuroVis. The goal of the BELIV workshop is to continue to provide a dedicated event for discussing visualization evaluation and to spread the word on alternative and novel evaluation methods and methodologies in our community.

Abstract

International audience; It is the year 2039, the desktop is not dead, and it does not look like this situation will change for a while. In any practical application domain in which data visualization is used, the desktop remains to be one of the most important tools for data exploration, analysis, and processing. Since the year 2014, non-desktop platforms for data exploration including large displays, immersive environments, tangible controls, and mobile devices have found their place for data visualization applications—but they have not and will not replace the desktop in many practically relevant tasks. Instead, researchers have finally begun to work toward an interactive visualization continuum that allows researchers and data analysts to transition between the different platforms and to use the tools for those tasks they support best: the desktop for in-depth, single-user analysis and novel platforms for group discussions, mobile data access, and/or good spatial perception.

Abstract

Extended abstract and poster; International audience; Our overall vision is to enable researchers to explore 3D datasets with as much immersion as possible, arising both from visuals as well as from interaction . We therefore explore ways to combine an immersive large view of the 3D data with means to intuitively control this view with touch input on a separate mobile monoscopic tablet. This combination has the potential to increase people's acceptance of stereoscopic environments for 3D data visualization since--through touch-based interaction--it puts them in control of their data. Moreover, the indirect manipulation of (stereoscopically displayed) 3D data on a personal touch device has been shown to have potentially more efficient and precise interaction than interaction directly on a large display.

Abstract

We present the results of a comprehensive analysis of visualization paper keywords supplied for 4366 papers submitted to five main visualization conferences. We describe main keywords, topic areas, and 10-year historic trends from two datasets: (1) the standardized PCS taxonomy keywords in use for paper submissions for IEEE InfoVis, IEEE Vis-SciVis, IEEE VAST, EuroVis, and IEEE PacificVis since 2009 and (2) the author-chosen keywords for papers published in the IEEE Visualization conference series (now called IEEE VIS) since 2004. Our analysis of research topics in visualization can serve as a starting point to (a) help create a common vocabulary to improve communication among different visualization sub-groups, (b) facilitate the process of understanding differences and commonalities of the various research sub-fields in visualization, (c) provide an understanding of emerging new research trends, (d) facilitate the crucial step of finding the right reviewers for research submissions, and (e) it can eventually lead to a comprehensive taxonomy of visualization research. One additional tangible outcome of our work is an application that allows visualization researchers to easily browse the 2600+ keywords used for IEEE VIS papers during the past 10 years, aiming at more informed and, hence, more effective keyword selections for future visualization publications.

Abstract

International audience; We present a systematic overview of the state-of-the art in research at the intersection of interactive displays and visualization. As the access to and analysis of information is becoming increasingly important anywhere and at any time, researchers have begun to investigate the role of interactive displays as data analysis platforms. Visualization applications play a crucial role in data analysis and development of dedicated systems and tools for small to large interactive displays to support such application contexts is underway. Researchers have investigated how to support data analysis with visualizations with dedicated interaction modalities such as touch, tangibles, or pens; have developed and studied applications for interactive displays such as tabletops or large wall displays; have studied the support of collaborative analysis around interactive displays; and provided toolkits and guidelines for writing software and designing a technical setup for data analysis with visualizations on interactive displays. We contribute a systematic and quantitative assessment of the literature from 10 different venues, an open repository of papers, and a code-set that can be used to categorize the research space. Our work points out that research has so far largely focused on the development of interaction techniques, for multi-touch tabletop devices, and 2D spatial and abstract visualizations.

Abstract

National audience; We investigate the dedicated control of multiple levels of semantic and sampling-based abstraction in 3D datasets, i.e., different types of data abstractions as opposed to sampling-based abstraction which shows more or less data. This dedicated navigation in the abstraction space facilitates the mental integration of different existing visualization techniques in many application areas including our example domain of fluid simulation. We realize the continuous abstraction control by interpolating between the levels while being able to simultaneously show multiple abstractions. We employ a halo-like shading technique based on distance fields to blend between several levels while continuously navigating between focus and context abstractions. We further add a semantic lens to find focus abstractions close to a user-defined context abstraction. Our entire implementation uses 2D image-based techniques to enable real-time performance, which seamlessly integrates within a 3D visualization tool.

Abstract

International audience; We revisit the concept of a 'gesture' and discuss it, in particular, in the context of 3D interaction. We argue that one should distinguish between postures, quasi-postures, and gestures and that the first two should be (and are currently) preferred in 3D interfaces for directly-manipulative interaction with the environment in user-maintained modes. In scientific visualization we saw use cases of quasi-postures, suggesting that they are one way to re-use the same input space in order to facilitate several means of exploration.

Abstract

By design, interactive tabletops and surfaces provide numerous opportunities for data visualization and analysis. In information visualization, scientific visualization, and visual analytics, useful insights primarily emerge from \emph{interactive} data exploration. Nevertheless, interaction research in these domains has largely focused on mouse-based interactions in the past, with little research on how interactive data exploration can benefit from interactive surfaces. These proceedings represent the results of the DEXIS 2011 Workshop on Data Exploration for Interactive Surfaces. It was held in conjunction with the ACM International Conference on Tabletops and Interactive Surfaces (ITS) in Kobe, Japan on November 13, 2011. The introduction summarizes the published papers of the workshop and points to results from workshop discussions. The remainder of the proceedings is made up of the position papers submitted to the workshop.

Abstract

International audience; Visualization has recently gained much relevance for its ability to cope with complex data analysis tasks and communication. While the overall use of visualizations is accelerating, the growth of specialized techniques for the evaluation of visualization systems has been slow. To understand the complex behaviors involved in analyzing data with visualization, evaluation efforts should be targeted at the component level, the system level, and the work environment level. The commonly used evaluation metrics such as task completion time and number of errors appear often insufficient to quantify the quality of a visualization system; thus the name of the BELIV workshop: "beyond time and errors …"The BELIV workshop series is a bi-annual event focusing on the challenges of evaluation in visualization. While it has been focused on information visualization in the past, BELIV 2012 aimed at gathering researchers in all fields of visualization to continue the exploration of novel evaluation methods, and to structure the knowledge on evaluation in visualization around a schema, where researchers can easily identify unsolved problems and research gaps.

Abstract

Extended abstract and poster, received Best Abstract Award at BioVis 2011; International audience; Based on an approach for the temporal change of abstraction in molecular visualization we describe how to achieve a spatially explicit control of abstraction. This allows us to depict different abstraction stages of a single molecule in a single still-image visualization. This approach works best for long, linear molecules with repeating substructures that allow viewers to visually compare the continuous representational changes of these parts.

Abstract

International audience; We would like to welcome all of you to the Seventh Annual Symposium on Computational Aesthetics in Graphics, Visualization, and Imaging (CAe). In addition to being colocated with ACM SIGGRAPH 2011, this year represents a milestone in collaboration. For the first time, CAe is being held as a joint together with the International ACM Symposium on Non-Photorealistic Animation and Rendering (NPAR) and the Eurographics Symposium on Sketch- Based Interfaces and Modeling (SBIM). This not only increases the audience and contributors, but allows for more effective cross-fertilization with researchers who have similar ideas, but rather different goals or methods.Computational Aesthetics core goal remains the bridging of the analytic and synthetic. This is achieved by integrating aspects of computer science, philosophy, psychology, and the fine, applied & performing arts. It seeks to facilitate both the analysis and the augmentation of creative behaviors. CAe also investigates the creation of tools that can enhance the expressive power of the fine and applied arts and furthers our understanding of aesthetic evaluation, perception and meaning. The symposium brings together individuals with technical experience of developing computer based tools to solve aesthetic problems and people with artistic/ design backgrounds who use these new tools.This year CAe received 39 submissions in total, 24 submissions in the technical papers track and 15 submissions in the art papers track. Due to the limited space in the joint symposium, we were only able to accepted 10 of the technical papers, resulting in an acceptance rate of roughly 42%. The technical submissions were distributed to an international program committee comprising 31 experts, resulting in at least 3 reviews for each paper. All of the accepted papers demonstrated both computational and aesthetic contributions.

Abstract

International audience; We present an example-based approach to synthesizing stipple illustrations for static 2D images that produces scaledependent results appropriate for an intended spatial output size and resolution. We show how treating stippling as a grayscale process allows us to both produce on-screen output and to achieve stipple merging at medium tonal ranges. At the same time we can also produce images with high spatial and low color resolution for print reproduction. In addition, we discuss how to incorporate high-level illustration considerations into the stippling process based on discussions with and observations of a stipple artist. Also, certain features such as edges can be extracted and used to control the placement of dots to improve the result. The implementation of the technique is based on a fast method for distributing dots using halftoning and can be used to create stipple images interactively. We describe both a GPU implementation of the basic algorithm that creates stipple images in real-time for large images and an extended CPU method that allows a finer control of the output at interactive rates.
