We first propose a table which allows us to explore the design space of composite mappings by offering a systematic overview of channel combinations. We expect that using more than one visual channel for communicating a data attribute increases the bandwidth of information presentation by displaying separable information on different aspects of data. In order to evaluate this point, we compare horizon graph, an existing technique which successfully adopts a composite visual mapping, with a selection of alternative composite mappings. We show that some of those mappings perform as well as –and in some cases even better than– horizon graph in terms of accuracy and speed.

To overcome this problem, this paper sets out to experimentally study an extendable tangible slider to support one-handed clutching. The tangible slider’s knob extends to maintain the thumb's movement within its comfortable area. We first built a low-fidelity prototype made of a knob long enough to allow clutching. This low-fidelity prototype significantly improves performance when reaching distant targets, as compared to a standard tangible slider. We then built a higher-fidelity prototype, introducing actuation and allowing for a shorter knob. When used for clutching, the knob moves back towards the users’ thumb. Experimental results show that the motion of the actuated knob does not interrupt eyes-free interaction during manipulation. In comparison, a graphical extendable slider performed 0.9s slower due to the required visual attention.

Participants were trained for the task either at the minimal delay the system allows (~9 ms) or at a longer delay equivalent to commercialized touch devices latencies (75 ms). After 10 training sessions over a minimum of two weeks (Experiment 1), participants adapt to the delay. They also display long-term retention seven weeks after the last training session. This adaptation generalized to a similar tracking path (e.g. infinity symbol). We also observed generalization of learning from the longer delay to the minimal delay condition (Experiment 2).

Based on our findings, we propose design guidelines for using composite visual mapping and combinations of optical visual channels in limited vertical screen resolution settings.\r\n", "authors": { "1": { "first_name": "Ali", "last_name": "Jabbari" }, "2": { "first_name": "Renaud", "last_name": "Blanch" }, "3": { "first_name": "Sophie", "last_name": "Dupuy-Chessa" } }, "year": 2018, "uri": "http://iihm.imag.fr/publication/JBD18b/", "pages": "73-82", "bibtype": "inproceedings", "id": 832, "abbr": "JBD18b", "address": "Brest, France", "date": "2018-10-23", "document": "http://iihm.imag.fr/publs/2018/IHM18-Jabbari-Composite.pdf", "type": "Conférences nationales avec comité de lecture sur texte complet", "booktitle": "Actes de la 30ème conférence francophone sur l'Interaction Homme-Machine (IHM 2018)" }, { "lang": "fr", "publisher": "ACM", "type_publi": "colcomlec", "title": "Fuzzy4U: un système en logique floue pour l’adaptation des interfaces utilisateur", "url": "https://hal.archives-ouvertes.fr/hal-01898998/document", "abstract": "User Interfaces adaptation is a well-known requirement in human-computer interaction.

Depending on the context, time series analysis are used for a variety of purposes: forecasting, estimation, classification, and trend and event detection. Thanks to the outstanding capabilities of human visual perception, visualization remains one of the most powerful tools for data analysis, particularly for time series. With the increase in data sets’ volume and complexity, new visualization techniques are clearly needed to improve data analysis. They aim to facilitate visual analysis in specified situations, tasks, or for unguided exploratory analysis.\r\n
\r\n\r\nVisualization is based upon visual mapping, which consists in association of data values to visual channels, e.g. position, size, and color of the graphical elements. In this regard, the most familiar form of time series visualization, i.e. line charts, consists in a mapping of data values to the vertical position of the line. However, a single visual mapping is not suitable for all situations and analytical objectives. Our goal is to introduce alternatives to the conventional visual mapping and find situations in which, the new approach compensate for the simplicity and familiarity of the existing techniques. We present a review of the existing literature on time series visualization and then, we focus on the existing approaches to visual mapping.\r\n
\r\n\r\nNext, we present our contributions. Our first contribution is a systematic study of a composite visual mapping which consists in using combinations of visual channels to communicate different facets of a time series. By means of several user studies, we compare our new visual mappings with an existing reference technique and we measure users’ speed and accuracy in different analytical tasks. Our results show that the new visual designs lead to analytical performances close to those of the existing techniques without being unnecessarily complex or requiring training. Also, some of the proposed mappings outperform the existing techniques in space constrained situations. Space efficiency is of great importance to simultaneous visualization of large volumes of data or visualization on small screens. Both scenarios are among the current challenges in information visualization.\r\n", "year": 2018, "uri": "http://iihm.imag.fr/publication/J18a/", "id": 833, "bibtype": "phdthesis", "abbr": "J18a", "authors": { "1": { "first_name": "Ali", "last_name": "Jabbari" } }, "date": "2018-07-04", "document": "http://iihm.imag.fr/publs/2018/these_ali.pdf", "type": "Thèses et habilitations", "pages": "121" }, { "lang": "fr", "type_publi": "these", "doi": "https://tel.archives-ouvertes.fr/tel-02007675", "title": "Visualisation de données temporelles personnelles", "url": "http://maverick.inria.fr/Members/Jeremy.Wambecke/", "abstract": "La production d’énergie, et en particulier la production d’électricité, est la principale responsable de l’émission de gaz à effet de serre au niveau mondial. Le secteur résidentiel étant le plus consommateur d’énergie, il est essentiel d’agir au niveau personnel afin de réduire ces émissions. Avec le développement de l’informatique ubiquitaire, il est désormais aisé de récolter des données de consommation d’électricité des appareils électriques d’un logement. Cette possibilité a permis le développement des technologies eco-feedback, dont l’objectif est de fournir aux consommateurs un retour sur leur consommation dans le but de la diminuer. Dans cette thèse nous proposons une méthode de visualisation de données temporelles personnelles basée sur une interaction what if, qui signifie que les utilisateurs peuvent appliquer des changements de comportement de manière virtuelle. En particulier notre méthode permet de simuler une modification de l’utilisation des appareils électriques d’un logement, puis d’évaluer visuellement l’impact de ces modifications sur les données. Cette méthode a été implémentée dans le système Activelec, que nous avons évalué avec des utilisateurs sur des données réelles.\r\n\r\nNous synthétisons les éléments de conception indispensables aux systèmes eco-feedback dans un état de l’art. Nous exposons également les limitations de ces technologies, la principale étant la difficulté rencontrée par les utilisateurs pour trouver des modifications de comportement pertinentes leur permettant de consommer moins d’énergie.\r\n\r\nNous présentons ensuite trois contributions.

Enfin la troisième contribution est l’évaluation in-situ du système Activelec dans des logements personnels pour une durée d’environ un mois. Activelec a été déployé dans trois appartements privés afin de permettre l’évaluation de notre méthode en contexte domestique réel. Dans ces trois expérimentations, les participants ont pu trouver des modifications d’utilisation des appareils qui économiseraient une quantité d’énergie significative, et qui ont été jugées faciles à appliquer en réalité.\r\n\r\nNous discutons également de l’application de notre méthode what if au-delà des données de consommation électrique au domaine de la visualisation personnelle, qui est définie comme l’analyse visuelle des données personnelles.

On mobile devices, sliders are represented graphically and are usually long and positioned in a vertical or horizontal way. These characteristics pose two major problems: a visual dependency to operate the graphical slider and a limited range of movement of the thumb when using the mobile device with a single hand. This thesis focuses on new eyes-free one-handed interaction techniques to efficiently operate sliders on mobile devices. The techniques rely on shape-changing tangible sliders capable of changing different design properties (e.g., orientation, length and side of the mobile device where it is presented) in order to support eyes-free one-handed interaction. Results from seven different experiments suggest that: 1) a conventional tangible slider delivers good performance but requires handgrip changes when acquiring targets in a distance range of 70mm. 2) a dual-side tangible slider delivers good performance and supports a stable handgrip when acquiring targets in a distance range of 100mm. 3) an extendable tangible slider delivers good performance and supports a stable handgrip when acquiring targets in a distance range of 200mm. Moreover, the performed experiments allowed the exploration of a part of shape-changing tangible user interfaces that has barely been studied: manipulation during shape-change. The performed studies show how different shape-changing design characteristics, like the orientation and amplitude, can impact the interaction.\r\n", "year": 2018, "uri": "http://iihm.imag.fr/publication/R18a/", "id": 851, "bibtype": "phdthesis", "abbr": "R18a", "authors": { "1": { "first_name": "Juan Pablo", "last_name": "Rosso Pirela" } }, "date": "2018-12-14", "document": "http://iihm.imag.fr/publs/2018/70059_ROSSO_PIRELA_2018_archivage.pdf", "type": "Thèses et habilitations", "pages": "252" }, { "lang": "en", "publisher": "The Eurographics Association", "doi": "http://dx.doi.org/10.2312/envirvis.20181140", "title": "What if we use the \"What if\" Approach for Eco-Feedback?

To overcome this limitation, we introduce in this paper Activelec, a system based on the visualization and interaction with user’s behavior rather than raw consumption data. The user’s behavior is modeled as the set of actions modifying the state of appliances over time. A key novelty of our solution is its focus on the What if approach applied to eco-feedback. Users can analyze and experiment scenarios by selecting and modifying their usage of electrical appliances over time and visualize the impact on the consumption. We conduct two user studies that evaluate the usability of Activelec and the relevance of the What if approach for electricity consumption. Our results show that users understand the interaction paradigm and can easily find relevant modifications in their usage of appliances. Moreover participants judge these changes of behavior would require little effort to be adopted.
