Abstract

International audience; We present a novel, web-based visual eye-tracking analytics tool called Gazealytics. Our open-source toolkit features a unified combination of gaze analytics features that support flexible exploratory analysis, along with annotation of areas of interest (AOI) and filter options based on multiple criteria to visually analyse eye tracking data across time and space. Gazealytics features coordinated views unifying spatiotemporal exploration of fixations and scanpaths for various analytical tasks. A novel matrix representation allows analysis of relationships between such spatial or temporal features. Data can be grouped across samples, user-defined AOIs or time windows of interest (TWIs) to support aggregate or filtered analysis of gaze activity. This approach exceeds the capabilities of existing systems by supporting flexible comparison between and within subjects, hypothesis generation, data analysis and communication of insights. We demonstrate in a walkthrough that Gazealytics supports multiple types of eye tracking datasets and analytical tasks.

Abstract

International audience; Studies on human decision-making focused on humanitarian aid have found that cognitive biases can hinder the fair allocation of resources. However, few HCI and Information Visualization studies have explored ways to overcome those cognitive biases. This work investigates whether the design of interactive resource allocation tools can help to promote allocation fairness. We specifically study the effect of presentation format (using text or visualization) and a specific framing strategy (showing resources allocated to groups or individuals). In our three crowdsourced experiments, we provided different tool designs to split money between two fictional programs that benefit two distinct communities. Our main finding indicates that individual-framed visualizations and text may be able to curb unfair allocations caused by group-framed designs. This work opens new perspectives that can motivate research on how interactive tools and visualizations can be engineered to combat cognitive biases that lead to inequitable decisions.

Abstract

International audience; Immersive technologies, like virtual and augmented reality, allow engaging the general public in interactive experiences, which are particularly promising in educational and cultural activities (e.g. museums, exhibits). For now, the design of such interactive experiences requires extensive knowledge of expert programming tools, and thus they are not accessible to non-developers. A promising method to ease the prototyping of interactive scenes for non-expert users stands on the concept of programming-by-demonstration. With such an approach, novice users can simply demonstrate an interaction or the expected behavior of a virtual object to build their prototype, without knowing the underlying coding mechanisms. In this paper, we propose an immersive authoring system that bases on that approach. We prototyped two use cases based on this system, as well as a user study. Using our observations and the results of the study, we discuss challenges associated with the design of such systems and provide guidelines for the development of future immersive programming-by-demonstration tools.; Les technologies immersives, comme la réalité virtuelle et augmentée, permettent de proposer au grand public des expériences interactives, particulièrement dans les activités éducatives et culturelles. Pour l’instant, la conception de telles expériences nécessite une connaissance approfondie de langages de programmation, difficilement accessibles aux non-développeurs. La programmation par démonstration est une approche qui permet de faciliter le prototypage de scènes interactives pour les utilisateurs non experts. Avec cette approche, les utilisateurs peuvent construire un prototype sans connaître les mécanismes de codages sous-jacents, simplement en effectuant l’interaction ou le comportement attendu d’un objet virtuel. Dans cet article, nous proposons un système de création immersif basé sur cette approche. Nous avons prototypé deux cas d’utilisations, ainsi que réalisé une étude utilisateur. En s’appuyant sur nos observations et les résultats de l’étude, nous discutons des défis et des lignes directrices pour le développement de futurs outils de programmation immersive par démonstration.

Abstract

International audience; A participatory data physicalization, or PDP, is a physical visualization that allows people to physically participate in the creation of the visualization, by directly encoding their data. PDPs offer a way to engage a community with data of personal relevance that otherwise would be intangible. However, their design space has only begun to be explored, and most prior work shows relatively simple encoding rules. Therefore, we present a design exploration of different ways of faceting contributed data: by week, day, or person. Specifically, we designed Edo, a PDP that allows a small community to contribute their data to a physical visualization showing the climate impact of their dietary choices. In this pictorial, we elaborate on the design process of Edo and reflect on the findings of a three-week deployment of different layouts of Edo. Fabrication instructions and data are available under CC-BY 4.0 at osf.io/q5fr6.

Abstract

International audience; Gesture elicitation studies are commonly used for designing novel gesture-based interfaces. There is a rich methodology literature on metrics and analysis methods that helps researchers understand and characterize data arising from such studies. However, deriving concrete gesture vocabularies from this data, which is often the ultimate goal, remains largely based on heuristics and ad hoc methods. In this paper, we treat the problem of deriving a gesture vocabulary from gesture elicitation data as a computational optimization problem. We show how to formalize it as an optimal assignment problem and discuss how to express objective functions and custom design constraints through integer programs. In addition, we introduce a set of tools for assessing the uncertainty of optimization outcomes due to random sampling, and for supporting researchers' decisions on when to stop collecting data from a gesture elicitation study. We evaluate our methods on a large number of simulated studies.

Abstract

International audience; The control of an avatar’s facial expressions in virtual reality is mainly based on the automated recognition and transposition of the user’s facial expressions. These isomorphic techniques are limited to what users can convey with their own face and have recognition issues. To overcome these limitations, non-isomorphic techniques rely on interaction techniques using input devices to control the avatar’s facial expressions. Such techniques need to be designed to quickly and easily select and control an expression, and not disrupt a main task such as talking. We present the design of a set of new non- isomorphic interaction techniques for controlling an avatar facial expression in VR using a standard VR controller. These techniques have been evaluated through two controlled experiments to help designing an interaction technique combining the strengths of each approach. This technique was evaluated in a final ecological study showing it can be used in contexts such as social applications.

Abstract

International audience; Traditional computer systems based on the WIMP paradigm (Window, Icon, Menu, Pointer) have shown potential benefits at school (e.g. for web browsing). On the other hand, they are not well suited as soon as hands-on and collaborative activities are targeted. We present CARDS, a Mixed-Reality system that combines together physical and digital objects in a seamless workspace to foster active and collaborative learning. We describe the design process based on a participatory approach with researchers, teachers, and pupils. We then present and discuss the results of a user study that tends to show that CARDS has a good educational potential for the targeted activities.

Abstract

International audience; Cerebral activity is an intangible physiological process that is difficult to apprehend, especially for children. To overcome this difficulty, Teegi was designed as a new type of educational support. This tangible interface enables children to discover the relationship between brain activity and the functions of the human body. We developed a multi-methods research approach to estimate the pedagogical potential of Teegi used in a real-life educational context. Using this interdisciplinary methodology, we conducted a user study (N=29) that highlighted the strengths of this interface, both in terms of its usability and its impact on learning. Moreover, results revealed possible improvements to further increase pedagogical effectiveness. This type of interface, as well as the evaluation method that we propose, contribute to extending our knowledge concerning the pedagogical use of new interactive tools at school.

Abstract

International audience; Estimating mental workload from brain signals such as Electroencephalography (EEG) has proven very promising in multiple Human-Computer Interaction (HCI) applications , e.g., to design games or educational applications with adaptive difficulty, or to assess how cognitively difficult to use an interface can be. However, current EEG-based workload estimation may not be robust enough for some practical applications. Indeed, the currently obtained work-load classification accuracies are relatively low, making the resulting estimations not fully trustable. This paper thus studies promising modern machine learning algorithms, including Riemannian geometry-based methods and Deep Learning, to estimate workload from EEG signals. We study them with both user-specific and user-independent calibration , to go towards calibration-free systems. Our results suggested that a shallow Convolutional Neural Network obtained the best performance in both conditions, outperform-ing state-of-the-art methods on the used data sets. This suggests that Deep Learning can bring new possibilities in HCI.

Abstract

International audience; In this demonstration we showcase a new spatial augmented reality device (interactive projection) with three applications: education and experimentation of color models, map exploration for visually impaired people and scientific vulgarization of machine learning. The first exhibition is an interactive exploration about the nature of light. Visitors can experiment with additive subtractive color models. We engage them with questions, and they have to reply using cards to find out answers. This exhibit is suitable for children. The second exhibition is about map exploration and creation for Visually Impaired Persons (VIP). VIP generally use tactile maps with braille to learn about an unknown environment. However, these maps are not accessible to the 80% of VIP who don't read braille. Our prototype augments raised-line maps with audio output. The third exhibition is destined to be used for scientific outreach. It enables the creation of artificial neural networks (ANN) using tangible interfaces. Neurons are represented by laser-cut diamond shaped tokens, and the data to learn is printed on cards. The ANN learns to differentiate shapes, and the whole learning process is made visible and interactive. These three applications demonstrate the capabilities of our hardware and software development kit in different scenarios. At ReVo, each demonstration will have its own setup and interactive space.

Abstract

International audience; The cerebral activity is an intangible physiological process difficult to apprehend, especially for children. With the aim of providing a new type of educational support, we studied the pedagogical potential of an interactive tangible interface (Teegi) designed to be used in educational context. This interface aims at enabling children to discover the relation between the brain activity and the human body functions. We propose in this study a methodology to evaluate its pedagogical potential in real context of use, considering the specificities of the children. This study, carried out with 29 pupils, highlights the strengths of this system, both in terms of its usability and its impact on learning. Moreover, the results provided by this methodology revealed possible improvements for a greater pedagogical effectiveness. This type of interactive interface, as well as the evaluation method proposed, paves the way for the pedagogical use of new interactive and tangible devices at school.; L’activité cérébrale est un processus physiologique intangible qui peut être difficile à appréhender, notamment pour des enfants. Pour répondre aux besoins en supports pédagogiques et favoriser les apprentissages liés à ce type de concepts, nous étudions le potentiel d’une interface tangible interactive dédiée à la visualisation d’activités cérébrales (Teegi) en contexte éducatif. Nous proposons une méthodologie d’évaluation du potentiel pédagogique en contexte réel d’utilisation par des enfants. Cette étude réalisée avec 29 enfants, met en évidence les forces de ce système, tant au niveau de son utilisabilité que de ses impacts sur les apprentissages visés. Les résultats obtenus mettent en lumière des axes d’améliorations possibles pour une plus grande efficacité pédagogique. Ce type d’interface, ainsi que la méthode d’évaluation que nous proposons, ouvrent la voie de l’utilisation pédagogique de nouveaux dispositifs interactifs et tangibles en milieu scolaire.

Abstract

International audience; Digital technology has been completely integrated into our daily lives, yet the potential of technology to improve its users’ life satisfaction is still largely untapped. Mindfulness, the act of paying a deliberate and non-judgmental attention to the present moment, has been shown to have a positive impact on a person’s health and subjective well-being – commonly called “happiness”. Based on an iterative process with meditation teachers and practitioners, we designed a new tool to support mindfulness practices. This tool takes the shape of an augmented sandbox, designed to inspire the user’s self-motivation and curiosity. By shaping the sand, the user creates a living miniature world that is projected back onto the sand. The natural elements of the garden are connected to real-time physiological measurements, such as breathing, helping the user to stay focused on the body. Moreover, using a Virtual Reality headset, they can travel inside their garden for a dedicated meditation session. Preliminary results seem to indicate that the system is well suited for mindfulness and induces a calm and mindful state on the user. The meditation teachers envisioned the use of Inner Garden in their practice.

Abstract

International audience; While physiological sensors enter the mass market and reach the general public, they are still mainly employed to monitor health – whether it is for medical purpose or sports. We describe an application that uses heart rate feedback as an incentive for social interactions. A traditional board game has been "augmented" through remote physiological sensing, using webcams. Projection helped to conceal the technological aspects from users. We detail how players reacted – stressful situations could emerge when users are deprived from their own signals – and we give directions for game designers to integrate physiological sensors.

Abstract

International audience; Interactive geographic maps are today widely available, but remain mostly limited to standard interaction contexts. We introduce a spatial augmented reality map, in which a virtual map is projected on a physical piece of paper. In a preliminary study we compared interaction techniques based on multi-touch, tangible and spatial modalities for three common map functions: zooming, panning, and changing the basemap. Our results suggest that object-based and spatial interaction may be advantageous over multi-touch in our augmented reality setup.

Abstract

International audience; Spatial augmented reality (SAR) promises the integration of digital information in the real (physical) world through projection. In this doctoral symposium paper, I propose different tools to fasten and ease the drawing by projecting photos, virtual construction lines and interactive 3D scenes. After describing them, I explain some future challenges to explore such as the creation of tools which helps to create drawings that are "difficult" to achieve for a human being, but easy to do by a computer. Furthermore, I propose some insights for the creation of digital games and programs which can take full advantages to have a human and physical constraints.
