Although ubiquitous data analysis is a promising approach, analyzing data in spreadsheets on tablets is a tedious task due to the limited size of the display and tactile vocabulary. In this article, we present the design and evaluation of new interaction techniques based on the combination of a tablet containing the data and a smartphone used as a mediator between the user and the tablet. To do this, we propose to use stacking gestures, i. e. to place a smartphone on top of a tablet. Stacking is an inexpensive, easy to implement, efficient and effective way to improve the analysis of data on tablets, increasing the vocabulary and broadening the display surface by using smartphones that are always available. We first explore stacking-based solutions to delimit the possible interaction vocabulary and present the manufacture of a conductive shell for smartphones. Then, we propose new techniques based on stacking to perform data analysis of a spreadsheet, i.e. the creation of pivot tables and their manipulation. We evaluate our stacking techniques against the tactile interactions provided by current mobile spreadsheet applications. Our studies reveal that some of our interaction techniques are 30% faster than touch to create pivot tables. Bien que l'analyse ubiquitaire de données soit une approche prometteuse, l'analyse des données dans des tableurs sur des tablettes est une tâche fastidieuse en raison de la taille limitée de l'affichage et du vocabulaire tactile. Dans cet article, nous présentons la conception et l'évaluation de nouvelles techniques d'interaction reposant sur la combinaison d'une tablette contenant les données et d'un smartphone utilisé comme médiateur entre l'utilisateur et la tablette. Pour ce faire, nous proposons d'utiliser des gestes de "stacking", c'est-à-dire de poser une arrête d'un smartphone sur l'écran de la tablette. Le stacking est un moyen peu coûteux, facile à mettre en oeuvre, efficace, et basé sur l'utilisation des smartphones toujours disponibles pour améliorer l'analyse des données sur des tablettes, en augmentant le vocabulaire utilisé et en élargissant la surface d'affichage. Nous explorons d'abord des solutions basées sur le stacking pour délimiter le vocabulaire d'interaction possible et présenter la fabrication d'une coque conductive pour smartphone. Ensuite, nous proposons de nouvelles techniques basées sur le stacking pour réaliser l'analyse de données d'un tableur, c'est-à-dire la création de tableaux croisés dynamiques et leur manipulation. Nous évaluons nos techniques de stacking par rapport aux interactions tactiles fournies par les applications de tableur mobiles actuelles. Nos études révèlent que certaines de nos techniques d'interaction sont 30% plus rapides que le toucher pour créer des tableaux croisés dynamiques.

Part 6: Wearable and Tangible Interaction; International audience; While ubiquitous data analytics is a promising approach, analyzing spreadsheets data on tablets is a tedious task due to the limited display size and touch vocabulary. In this paper, we present the design and evaluation of novel interaction techniques relying on the combination of a tablet, holding the data, and a smartphone, used as a mediator between the user and the tablet. To this end, we propose to use stacking gestures, i.e. laying one edge of a smartphone on the tablet screen. Stacking is a cheap, easy to implement and effective way of employing always-available smartphones to improve data analysis on tablets, by augmenting the input vocabulary and extending the display surface. We first explore stacking gestures to delimitate the possible interaction vocabulary and present the manufacturing of a conductive smartphone case. Then, we propose novel stacking-based techniques to perform spreadsheet data analysis, i.e. pivot table creation and manipulation. We evaluate our stacking techniques against touch interaction as provided by current mobile spreadsheet apps. Our studies reveal that some of our interaction techniques perform 30% faster than touch for creating pivot tables.

International audience; 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.; L’interaction multi-touch avec des tableurs sur tablette soulève de nombreuses problématiques d’interaction. Dans cet article, nous présentons la conception et l’évaluation de nouvelles techniques d’interaction basées sur l’utilisation d’un dispositif courant, le smartphone, afin de faciliter l’interaction avec les tableurs sur tablette. Le smartphone peut être utilisé comme écran additionnel, permettant l’affichage d’une plus grande quantité d’informations ou comme interacteur tangible, étendant ainsi le vocabulaire d’interaction tactile au travers de gestes de stacking. Nous essayons en particulier de simplifier la création de tableaux croisés dynamiques, tâche classique de l’analyse de données sur tableur. Nous comparons nos techniques à l’interaction tactile classique proposée par les tableurs. Nos résultats montrent que certaines de nos techniques d’interaction sont 23.1% plus rapides que le tactile pour la création de tableaux croisés dynamiques.

International audience; 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.

International audience; Multitouch interaction with spreadsheets on mobile devices raises multiple interaction issues. In this paper, we present the design and evaluation of novel interaction techniques for spreadsheet based on the stacking paradigm, which consists in laying one edge/face/corner of a smartphone on a tablet screen. We first explore the available gestures and degrees of freedom of our prototype to delimitate the possible interaction's vocabulary. Then, we propose novel interaction techniques to perform range selection in a spreadsheet on a tablet. To detect the smartphone on the tablet screen, we conceive a conductive smartphone copper-shell. We evaluate our prototype against the regular tactile interactions provided by spreadsheet apps. Our studies reveal that some of our interaction techniques perform between 15% and 20% faster for range selection.; L'interaction multitouch avec des tableurs sur tablettes soulève de nombreuses problématiques d'interaction. Dans cet article, nous présentons la conception et l'évaluation de nouvelles techniques d'interaction pour tableurs basées sur une manipulation de type stacking, qui consiste à poser l'arête/le coin/la face d'un smartphone sur l'écran d'une tablette. Dans un premier temps, nous explorons l'espace des gestes et les degrés de libertés du stacking afin de délimiter le vocabulaire d'interaction possible. Ensuite, nous proposons plusieurs techniques d'interaction pour réaliser la tâche de sélection de plages de données dans un tableur sur tablette.

Nos résultats montrent que certaines de nos techniques d'interaction sont entre 15% et 20% plus rapides que le tactile pour sélectionner une plage de données.

International audience; We present the design and evaluation of the Roly-Poly Mouse (RPM), a rolling input device that combines the advantages of the mouse (position displacement) and of 3D devices (roll and rotation) to unify 2D and 3D interaction. Our first study explores RPM gesture amplitude and stability for different upper shapes (Hemispherical, Convex) and hand postures. 8 roll directions can be performed precisely and their amplitude is larger on Hemispherical RPM. As minor rolls affect translation, we propose a roll correction algorithm to support stable 2D pointing with RPM. We propose the use of compound gestures for 3D pointing and docking, and evaluate them against a commercial 3D device, the SpaceMouse. Our studies reveal that RPM performs 31% faster than the SpaceMouse for 3D pointing and equivalently for 3D rotation. Finally, we present a proof-of-concept integrated RPM prototype along with discussion on the various technical challenges to overcome to build a final integrated version of RPM.

This paper presents the design of a new device, DISCO. In addition to the traditionnal mouse capabilities, DISCO offers multiple degrees of freedom suitable for multidimensioannl data manipulation. We present various usage scenarios and explore the handling of this device through two studies. First we observe the user's hand posture on three versions of Disco with different form factors. Then we study the capabilities and limitations related to physical translations, rotations (yaw) and tilt (pitch, roll) on two versions of Disco according to three hand postures. Based on the results, we propose design guidelines to create interaction techniques that take benefit of the degrees of freedom of the device to interact with multidimensional data.

As public displays integrate 3D content, Overview+Detail (O+D) interfaces on mobile devices will allow for a personal 3D exploration of the public display. In this paper we study the properties of mobile-based interaction with O+D interfaces on 3D public displays. We evaluate three types of existing interaction techniques for the 3D translation of the Detail view: touchscreen input, mid-air movement of the mobile device (Mid-Air Phone) and mid-air movement of the hand around the device (Mid-Air Hand). In a first experiment, we compare the performance and user preference of these three types of techniques with previous training. In a second experiment, we study how well the two mid-air techniques perform with no training or human help to imitate usual conditions in public context. Results reveal that Mid-Air Phone and Hand perform best with training. However, without training or human help Mid-Air Phone is more intuitive and performs better on the first trial. Interestingly, on both experiments users preferred Mid-Air Hand. We conclude with a discussion on the use of mobile devices to interact with public O+D interfaces.
