Experimenting and improving perception of 3D rotation-based transitions between 2D visualizations

Part 1: Long and Short PapersInternational audienceExploring a multidimensional dataset with visualization requires to transition between points of view. In order to enable users to understand transitions, visualization can employ progressive 3D rotations. However, existing implementations of progressive 3D rotation exhibit some perception problems with visualization of cluttered scene. In this paper, we present a first experiment showing how existing 3D rotation is effective for tracking marks, and that cluttered scenes actually hinder perception of rotation. Then, we propose to set the axis of rotation on the graphical marks of interest, and ran a second experiment showing that focus-centered rotation improves perception of relative arrangement

Amélioration du circuit visuel des contrôleurs aériens pour relier les données entre visualisations en utilisant des transitions animées

International audienceSeveral separate displays are used by Air Traffic Controllers, such as radar view, flight lists view or paper strips. In order to link the information between these views and keep focus on a subset of flights, controllers are required to do visual operations (eye gaze, analysis of visual properties etc.). This process can be disruptive when traffic increases and when visualizations display large amounts of objects. In this paper we propose the use of animated transitions to replace the visual paths controllers take. We discuss this technique and show results of a predictive evaluation that suggests an improvement in users' performance

When paper meets multi-touch : a study of multi-modal interactions in air traffic controls

International audienceWhen multiple modes of interaction are available, it is not obvious whether combining these technologies necessarily leads to a better user experience. It can be difficult to determine which modes are most appropriate for each interaction. However, complex activities such as air traffic control require multiple interaction techniques and modalities. As a result, in this paper, we study the technical challenges of adding finger detection to an augmented flight strip board used by air traffic controllers. We use our augmented strip board to evaluate interactions based on touch, digital pen and physical paper objects. From our user study, we find that users are able to quickly adapt to an interface that offers such a wide range of modalities. The availability of different modalities did not overburden the users and they did not find it difficult to determine the appropriate modality to use for each interaction

Hanstreamer: an Open-source Webcam-based Live Data Presentation System

We present Hanstreamer, a free and open-source system for webcam-based data presentation. The system performs real-time gesture recognition on the user's webcam video stream to provide interactive data visuals. Apart from the standard chart and map visuals, Hanstreamer is the first such video data presentation system to support network visualisation and interactive DimpVis-style time-series data exploration. The system is ready for use with popular online meeting software such as Zoom and Microsoft Teams.Comment: 3 pages, 5 figure

Exploration et gestion des connaissances des ressources en IHM

National audienceNous présentons dans l' article le résultat d'un travail réalisé à l'école de Printemps 2010 de l'AFIHM. L'analyse des activités liées à la réalisation d' un état de l'art nous montre qu'une des tâches les plus compliquées est la familiarisation avec un nouveau domaine. Pour outiller cette activité, nous présentons des pistes de réflexion basées sur une analogie avec la mémoire humaine
