Flex-ER: A platform to evaluate interaction techniques for immersive visualizations / María-Jesús Lobo in Proceedings of the ACM on Human-Computer Interaction, Vol 4 (November 2020)  

Public [article]  inProceedings of the ACM on Human-Computer Interaction > Vol 4 (November 2020) . - n° 195 Titre : Flex-ER: A platform to evaluate interaction techniques for immersive visualizations Type de document : Article/Communication Auteurs : María-Jesús Lobo , Auteur ; Christophe Hurter, Auteur ; Pourang Polad Irani, Auteur Année de publication : 2020 Projets : 2-Pas d'info accessible - article non ouvert / Article en page(s) : n° 195 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] environnement de développement [Termes IGN] format JSON [Termes IGN] plateforme logicielle [Termes IGN] visualisation de données [Termes IGN] vue immersive [Vedettes matières IGN] Géovisualisation Mots-clés libres : Flex-ER Résumé : (auteur) Extended Reality (XR) systems (which encapsulate AR, VR and MR) is an emerging field which enables the development of novel visualization and interaction techniques. To develop and to assess such techniques, researchers and designers have to face choices in terms of which development tools to adopt, and with very little information about how such tools support some of the very basic tasks for information visualization, such as selecting data items, linking and navigating. As a solution, we propose Flex-ER, a flexible web-based environment that enables users to prototype, debug and share experimental conditions and results. Flex-ER enables users to quickly switch between hardware platforms and input modalities by using a JSON specification that supports both defining interaction techniques and tasks at a low cost. We demonstrate the flexibility of the environment through three task design examples: brushing, linking and navigating. A qualitative user study suggest that Flex-ER can be helpful to prototype and explore different interaction techniques for immersive analytics.

However, as a secondary source, it has a different methodological origin than travel survey data, usually relying on unsupervised algorithms, and so it requires to be assessed as a dataset. This assessment is challenging, because, in general, there is not a benchmark dataset or a ground truth scenario available, as travel surveys only represent a partial view of the phenomenon and suffer from their own biases. For this critical task, which involves urban planners and data scientists, we study the design space of the visualization of cross-origin, multivariate flow datasets. For this purpose, we introduce the Modalflow system, which incorporates and adapts different visualization techniques in a notebook-like setting, presenting novel visual encodings and interactions for flows with modal partition into scatterplots, flow maps, origin-destination matrices, and ternary plots. Using this system, we extract general insights on visual analysis of pervasive and survey data for urban mobility and assess a mobile phone network dataset for one metropolitan area.

How do display design and user characteristics matter in animations? An empirical study with air traffic control displays / Sara Maggi in Cartographica, vol 51 n° 1 (Spring 2016)  

Public [article]  inCartographica > vol 51 n° 1 (Spring 2016) . - pp 25 - 37 Titre : How do display design and user characteristics matter in animations? An empirical study with air traffic control displays Type de document : Article/Communication Auteurs : Sara Maggi, Auteur ; Sara Irina Fabrikant, Auteur ; Jean-Paul Imbert, Auteur ; Christophe Hurter, Auteur Année de publication : 2016 Article en page(s) : pp 25 - 37 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] animation graphique [Termes IGN] cartographie animée [Termes IGN] objet mobile [Termes IGN] oculométrie [Termes IGN] trafic aérien [Termes IGN] utilisateur [Termes IGN] visualisation de données [Vedettes matières IGN] Géovisualisation Résumé : (auteur) We detail an empirical animation study to assess how display design, user spatial ability, and training might influence visuospatial decision-making with animated displays showing aircraft movements. We present empirical results of a visuospatial detection task with moving objects, based on response accuracy and response time, including a descriptive eye-movement analysis. We found significant differences in a visuospatial detection task of moving objects across animation design types and domain expertise levels based on viewers’ visuospatial skill differences. With this empirical approach, we hope to better understand how users explore and extract information from animated displays. Based on these results, we aim to further develop empirically validated animation display design guidelines to increase their efficiency and effectiveness for decision-making with and about moving objects.
