On-Body tangible interaction: using the body to support tangible manipulations for immersive visualization

Abstract: Recent technological advancements in augmented and mixed reality devices opened up many opportunities to users to interact in their environments. However, there are many unanswered questions about the definition of these interaction paradigms. In this article, we present a new approach to interact in these environments: using the body as a physical support to constrain the movement of a multiple degrees of freedom device (3D Mouse). This mouse offers enough degrees of freedom as well as a necessary accuracy to support the interaction. The use of the body as a support for the interaction allows the user to move in his environment and avoids the inherent fatigue of mid-air interactions. Thus, we propose a new design space for tangible interactions on the body, and specifically on the forearm. To validate the feasibility of such an approach, we present an experiment aimed at establishing the range, stability and comfort of gestures performed with a multiple degrees of freedom mouse on the forearm.

Rolling-Menu: Rapid Command Selection in Toolbars Using Roll Gestures with a Multi-DoF Mouse

Abstract: This paper presents Rolling-Menu, a technique for selecting toolbar items, based on the use of roll gestures with a multidimensional device, the Roly-Poly Mouse (RPM). Rolling-Menu reduces object-command transition, resulting in a better integration between command selection and direct manipulation of application objects. Selecting a toolbar item with Rolling-Menu requires rolling RPM in a predefined direction corresponding to the item. We propose a design space of Rolling-Menu that includes different roll mapping and validation modes. A first user's study, with a simple toolbar containing up to 14 items, establishes that the best version of Rolling-Menu takes, on average, up to 29% less time than the Mouse to select a toolbar item. Moreover accuracy of the selection with Rolling-Menu is above 90%. Both the validation mode and the mapping between roll direction and toolbar items influence the performance of Rolling-Menus. A second study compares the three best versions of Rolling-Menu with the Mouse to select an item in two types of multidimensional toolbars: a toolbar containing dropdown lists, and a grid toolbar. Results confirm the advantage of Rolling-Menu over a Mouse.

DichotoZoom: selection technique in a 3D virtual environment displayed on smartphone

Abstract: Except for video games, the use of 3D virtual environment (3D VE) on Smartphone has not yet been popularized. This is due to lack of interaction techniques to interact with a 3D VE composed of many objects. In this article, we focus on selecting objects in dense 3D VE. We propose DichotoZoomwhich allows the selection of objects inside a set of already pre-selected ones, with a limited number of actions. In a first study, we compare our technique with the Circulation technique, suggested by the literature. This study shows the effectiveness of DichotoZoomwhen the set contain significantly numerous elements. Finally, we studied its use with various interaction modalities used on Smartphone : using physical or graphical buttons, and gestural interactions via touch screen or moving the device itself.

A Novel Interaction Paradigm For Exploring Spatio-Temporal Data

Abstract: Complex spatio-temporal data is difficult to visualize and even further to interact with, especially by several users at the same time. However, visualization and exploration of such data are essential for experts to understand complex data environments, such as for mitigating the adverse effects of disease spread. This paper presents an alternative approach to that of current spatiotemporal data visualizations to access, interpret, and manipulate spatio-temporal datasets as a single user or as a team. Our approach uses tangible and visual tools such as mini-robots, tabletop displays and augmented reality tools, to facilitate the data exploration and interpretation. We also introduce a simple use case that illustrates one of the possible utilization of the system. While tangibles have been introduced to represent information, we are investigating manners in which we can depict even more complex datasets. Our system will provide a novel approach to manipulate 3D and 4D datasets that classic tools such as a 2D mouse or a tactile screen would not allow.

DichotoZoom : Technique de sélection d'objets dans un environnement virtuel 3D affiché sur Smartphone

Abstract: Hormis pour les jeux video, l’utilisation d’environnement virtuel 3D (EV 3D) sur Smartphone n’est pas encore democratisee. Ceci est du au manque de techniques d’interaction proposees pour in- teragir avec un EV 3D compose de nombreux objets. Dans cet article, nous nous interessons a la selection d’objets dans des EV 3D denses. Nous proposons DichotoZoomqui permet la selection d’objets parmi un ensemble d’objets deja preselectionnes, en un nombre d’actions limite. Dans une premiere etude, nous comparons notre technique a la technique Circulation, proposee par la littera- ture. Celle-ci montre l’efficacite de DichotoZoomlorsque l’ensemble presente un nombre d’elements important. Enfin, nous avons etudie son usage avec differentes modalites d’interaction utilisables sur Smartphone : utilisation de boutons physiques ou sous forme de composants graphiques, interactions gestuelles au moyen de l’ecran tactile ou du Smartphone lui-meme.

A pen-based bimanual approach for interaction in multi-display environments

Abstract: Recent advances in multi-display environments (MDE) has led researchers to develop separated interaction techniques for separated MDE tasks. However, these techniques were not adapted to realistic usage situations. Additionally, when the use of a pen tablet is required, to annotate a document for example, its use in combination with the standard keyboard and mouse often results in homing time cost. In this paper we explore a bimanual approach to support major MDE tasks: it is based on the combination of a multi-degree of freedom device and a pen. Moreover, we explain our approach and current implementation. Finally, we discuss our future work and envisioned studies to evaluate the usability of such an approach.

Utilisation du corps comme support à l'interaction à distance avec un dispositif à multiple degrés de libertés

Abstract: Les recents avenements technologiques au travers des peripheriques de realite augmente ou mixte ouvrent de nombreuses opportunites aux utilisateurs pour interagir dans leurs environnements. Cependant, il reste de nombreuses questions sur la definition de ces paradigmes d’interaction. Dans cet article, nous presentons une nouvelle approche avec l’utilisation du corps comme support physique pour contraindre les deplacements d’un peripherique de type souris 3D. Cette souris offre suffisamment de degres de liberte et une precision satisfaisante pour supporter l’interaction. L’utilisation du corps comme support a l’interaction permet a l’utilisateur de se deplacer dans son environnement et reduit la fatigue inherente a l’interaction en l’air. Ainsi, nous proposons un nouvel espace de conception pour les interactions tangibles sur le corps, et en particulier sur l’avant-bras. Pour valider la faisabilite d’une telle approche, nous presentons une experience visant a etablir la portee, stabilite et confort des gestes effectues avec une souris 3D sur l’avant-bras.

A new approach for spatio-temporal data mining

Abstract: Spatio-temporal datasets (STD) are generated daily. Generally, their visualization includes 2D renderings or animated visualizations that do not fit to the exploration of such complex data. In this paper, we present an alternative approach to current STD visualizations. Our approach uses tangible and visual tools such as mini-robots and a tactile interaction screen to facilitate access, interpretation and manipulation of this kind of data. While tangible elements have been introduced to represent information, our system provides a new approach to explore multidimensional datasets that conventional tools would not allow.

Combination of tactile devices to interact with a spreadsheet on tablet

Abstract: Multi-touch interaction with spreadsheets on tablets is tedious and raises multiple interaction issues. In this paper, we present the design and evaluation of novel interaction techniques relying on the usage of an always-available device, the smartphone, to improve interaction with spreadsheets on tablets. The smartphone can be used as an additional screen, allowing to display more information or as a tangible interactor, thus extending the tactile interaction vocabulary through stacking gestures. Our techniques aim to facilitate the creation of pivot tables, a common task in data analysis on spreadsheets. We evaluate our stacking techniques against the tactile interactions provided by mobile spreadsheet apps. Our studies reveal that some of our interaction techniques are 23.1% faster than tactile for creating pivot tables.

Combinaison de dispositifs tactiles pour interagir avec un tableur sur tablette

Abstract: L’interaction multi-touch avec des tableurs sur tablette souleve de nombreuses problematiques d’interaction. Dans cet article, nous presentons la conception et l’evaluation de nouvelles techniques d’interaction basees sur l’utilisation d’un dispositif courant, le smartphone, afin de faciliter l’interaction avec les tableurs sur tablette. Le smartphone peut etre utilise comme ecran additionnel, permettant l’affichage d’une plus grande quantite d’informations ou comme interacteur tangible, etendant ainsi le vocabulaire d’interaction tactile au travers de gestes de stacking. Nous essayons en particulier de simplifier la creation de tableaux croises dynamiques, tache classique de l’analyse de donnees sur tableur. Nous comparons nos techniques a l’interaction tactile classique proposee par les tableurs. Nos resultats montrent que certaines de nos techniques d’interaction sont 23.1% plus rapides que le tactile pour la creation de tableaux croises dynamiques.

Cell Selection for Spreadsheets on Tablets: Stacking-Based Interaction

Abstract: Spreadsheets on tablet, based on multitouch interaction is tedious and raises multiple interaction issues such as screen size or limited tactile interaction. To answer this limitations, we propose the use of the stacking paradigm, which consists in laying one edge of a smartphone on a tablet screen. It offers the double benefit of augmenting the input vocabulary and extending the display surface. We built a prototype based on a 3D printed shell augmented with copper to detect the smartphone on the tablet screen. We also developed a simplified spreadsheet app on the tablet in which users can select cells using three stacking-based interaction techniques.
