Texto completo da fonteLarge data sets are used acceleratingly in various professional domains, such as medicine and business. This rises challenges in managing and using them, typically including sense-making, searching and classifying. This does not only require advanced algorithms to process the data sets automatically, but also need users' direct interaction to make initial judgment or to correct mistakes from the machine work. This dissertation explores this problem domain and study users' direct interaction with scattered large data sets. Human body is made for interacting with the physical world, from micro scope to very large scales. We can naturally coordinate ourselves to see, hear, touch and move to interact with the environment in various scales. Beyond individual, humans collaborate with each other through communication and coordination. Based on Dourish's definitioncite{2001:AFE:513034}, Embodied Interaction encourages interaction designers to take advantage of users' existing skills in the physical world, when designing the interaction with digital artefacts. I argue that large interactive spaces enable embodied user interaction with data spread over space, by leveraging users' physical abilities such as walking, approaching and orienting. Beyond single users, co-located environments provide multiple users with physical awareness and verbal gestural communication. While single users' physical actions have been augmented to be various input modalities in existing research, the augmentation of between-user resources has been less explored. In this dissertation, I first present an experiment that formally evaluates the advantage of single users performing a data manipulation task on a wall-sized display, comparing to on a desktop computer. It shows that using users' physical movements to navigate in a large data surface, outperforms existing digital navigation techniques on a desktop computer such as Focus+Context. With the same experimental task, I then study the interaction efficiency of collaborative data manipulation with a wall-sized display, in loosely or closely coupled collaboration styles. The experiment measures the effect of providing a Shared Interaction Technique, in which collaborators perform part of an action each to issue a command. The results conclude its benefits in terms of efficiency, user engagement as well as physical fatigue. Finally, I explore the concept of augmenting human-to-human interaction with shared interaction techniques, and illustrate a design space of such techniques for supporting collaborative data manipulation. I report the design, implementation and evaluation of a set of these techniques and discuss the future work
Romat, Hugo. "From data exploration to presentation : designing new systems and interaction techniques to enhance the sense-making process". Thesis, Université Paris-Saclay (ComUE), 2019. http://www.theses.fr/2019SACLS335/document.
Texto completo da fonteDuring the last decade, the amount of data has been constantly increasing. These data can come from several sources such as smartphones, audio recorders, cameras, sensors, simulations, and can have various structure. While computers can help us process these data, human judgment and domain expertise is what turns the data into actual knowledge. However, making sense of this increasing amount of diverse data requires visualization and interaction techniques. This thesis contributes such techniques to facilitate data exploration and presentation, during sense-making activities. In the first part of this thesis, we focus on interactive systems and interaction techniques to support sense-making activities. We investigate how users work with diverse content in order to make them able to externalize thoughts through digital annotations. We present our approach with two systems. The first system, ActiveInk enables the natural use of pen for active reading during a data exploration process. Through a qualitative study with eight participants, we contribute observations of active reading behaviors during data exploration and design principles to support sense-making. The second system, SpaceInk, is a design space of pen & touch techniques that make space for in-context annotations during active reading by dynamically reflowing documents. In the second part, we focus on techniques to visually represent insights and answers to questions that arise during sense-making activities. We focus on one of the most elaborate data structures: multivariate networks, that we visualize using a node-link diagram visualization. We investigate how to enable a flexible iterative design process when authoring node-link diagrams for multivariate networks. We first present a system, Graphies, that enables the creation of expressive node-link diagram visualizations by providing designers with a flexible workflow that streamlines the creative process, and effectively supports quick design iterations. Moving beyond the use of static visual variables in node-link diagrams, we investigated the use of motion to encode data attributes. To conclude, we show in this thesis that the sense-making process can be enhanced in both processes of exploration and presentation, by using ink as a new medium to transition between exploration and externalization, and by following a flexible, iterative process to create expressive data representations. The resulting systems establish a research framework where presentation and exploration are a core part of visual data systems
Cavez, Vincent. "Designing Pen-based Interactions for Productivity and Creativity". Electronic Thesis or Diss., université Paris-Saclay, 2025. http://www.theses.fr/2025UPASG013.
Texto completo da fonteDesigned with the mouse and keyboard in mind, productivity tools and creativity support tools are powerful on desktop computers, but their structure becomes an obstacle when brought to interactive surfaces supporting pen and touch input.Indeed, the opportunities provided by the pen for precision and expressivity have been demonstrated in the HCI literature, but productivity and creativity tools require a careful redesign leveraging these unique affordances to take benefit from the intuitiveness they offer while keeping the advantages of structure. This delicate articulation between pen and structure has been overlooked in the literature.My thesis work focuses on this articulation with two use cases to answer the broad research question: “How to design pen-based interactions for productivity and creativity on interactive surfaces?” I argue that productivity depends on efficiency while creativity depends on both efficiency and flexibility, and explore interactions that promote these two dimensions.My first project, TableInk, explores a set of pen-based interaction techniques designed for spreadsheet programs and contributes guidelines to promote efficiency on interactive surfaces. I first conduct an analysis of commercial spreadsheet programs and an elicitation study to understand what users can do and what they would like to do with spreadsheets on interactive surfaces. Informed by these, I design interaction techniques that leverage the opportunities of the pen to mitigate friction and enable more operations by direct manipulation on and through the grid. I prototype these interaction techniques and conduct a qualitative study with information workers who performed a variety of spreadsheet operations on their own data. The observations show that using the pen to bypass the structure is a promising mean to promote efficiency with a productivity tool.My second project, EuterPen, explores a set of pen-based interaction techniques designed for music notation programs and contributes guidelines to promote both efficiency and flexibility on interactive surfaces. I first conduct a series of nine interviews with professional composers in order to take a step back and understand both their thought process and their work process with their current desktop tools. Building on this dual analysis, I derive guidelines for the design of features which have the potential to promote both efficiency with frequent or complex operations and flexibility in regard to the exploration of ideas. Then, I act on these guidelines by engaging in an iterative design process for interaction techniques that leverage the opportunities of the pen: two prototyping phases, a participatory design workshop, and a final series of interviews with eight professional composers. The observations show that on top of using the pen to leverage the structure for efficiency, using its properties to temporarily break the structure is a promising mean to promote flexibility with a creativity support tool.I conclude this manuscript by discussing several ways to interact with structure, presenting a set of guidelines to support the design of pen-based interactions for productivity and creativity tools, and elaborating on the future applications this thesis opens

Texto completo da fontePour les ED, notre objectif a été d'apporter des solutions pour la modélisation de l'évolution des données décisionnelles (extension de modèle objet) et pour l'intégration de données textuelles sans en fixer le schéma à priori. Pour les MD, nous avons proposé un modèle multidimensionnel de base avec différentes extensions répondant aux besoins des décideurs. Ces extensions permettent de prendre en compte la gestion d'indicateurs et de données textuelles, l'évolution temporelle (versions), la cohérence des données et de ses analyses (contraintes sémantiques), l'intégration et la capitalisation de l'expertise des décideurs (annotations) ainsi que la personnalisation des schémas multidimensionnels (poids). Ces travaux ont été complétés par la proposition d'une démarche de conception qui présente l'avantage de prendre en compte les besoins des décideurs et les sources de données. Cette démarche permet de modéliser aussi bien l'aspect statique (données décisionnelles) que l'aspect dynamique (processus d'alimentation du SAD).
D'un point de vue manipulation des données, nous avons proposé une algèbre complétée d'un langage graphique orienté décideur et d'un langage déclaratif. Nos propositions ont été validées par la participation à différents projets ainsi que le co-encadrement de 5 thèses de doctorat et le suivi de travaux de plusieurs Master Recherche.

Texto completo da fonteAu niveau de l'entrepôt, nous définissons un modèle de données permettant de décrire l'évolution temporelle des objets complexes. Dans notre proposition, l'objet entrepôt intègre des états courants, passés et archivés modélisant les données décisionnelles et leurs évolutions. L'extension du concept d'objet engendre une extension du concept de classe. Cette extension est composée de filtres (temporels et d'archives) pour construire les états passés et archivés ainsi que d'une fonction de construction modélisant le processus d'extraction (origine source). Nous introduisons également le concept d'environnement qui définit des parties temporelles cohérentes de tailles adaptées aux exigences des décideurs. La manipulation des données est une extension des algèbres objet prenant en compte les caractéristiques du modèle de représentation de l'entrepôt. L'extension se situe au niveau des opérateurs temporels et des opérateurs de manipulation des ensembles d'états.
Au niveau des magasins, nous définissons un modèle de données multidimensionnelles permettant de représenter l'information en une constellation de faits ainsi que de dimensions munies de hiérarchies multiples. La manipulation des données s'appuie sur une algèbre englobant l'ensemble des opérations multidimensionnelles et offrant des opérations spécifiques à notre modèle. Nous proposons une démarche d'élaboration des magasins à partir de l'entrepôt.
Pour valider nos propositions, nous présentons le logiciel GEDOOH (Générateur d'Entrepôts de Données Orientées Objet et Historisées) d'aide à la conception et à la création des entrepôts dans le cadre de l'application médicale REANIMATIC.

Texto completo da fonteIn decisional system framework, my thesis focuses on the conception and the querying of multidimensional data. We provide a constraint-based dimensional model organising data in a constellation of facts (subject of analysis), which are associated with dimensions (axes of analysis). These dimensions are flexible because each dimension instance can belong to one or several hierarchies (perspectives of analysis). Moreover, we integrate constraints in the multidimensional model allowing both the validation of multidimensional structures and consistent analyses by disambiguating null values, which can result from the combination of unsuitable hierarchies. To integrate these constraints, we define a multidimensional algebra enabling decision-makers to precise analysed instances. Finally, we provide a conceptual design method of multidimensional data integrating decision-maker needs and data issued from source schema. To validate our propositions, we provide a CASE tool to help designer to define conceptual multidimensional schema

Texto completo da fonteRecently, the “Web of Documents” has become the “Web of Data”, i.e., the documents are annotated in the form of RDF making this human processable data directly processable by machines. This data can further be explored by the user using SPARQL queries. As web clustering engines provide classification of the results obtained by querying web of documents, a framework for providing classification over SPARQL query answers is also needed to make sense of what is contained in the data. Exploratory Data Mining focuses on providing an insight into the data. It also allows filtering of non-interesting parts of data by directly involving the domain expert in the process. This thesis contributes in aiding the user in exploring Linked Data with the help of exploratory data mining. We study three research directions, i.e., 1) Creating views over RDF graphs and allow user interaction over these views, 2) assessing the quality and completing RDF data and finally 3) simultaneous navigation/exploration over heterogeneous and multiple resources present on Linked Data. Firstly, we introduce a solution modifier i.e., View By to create views over RDF graphs by classifying SPARQL query answers with the help of Formal Concept Analysis. In order to navigate the obtained concept lattice and extract knowledge units, we develop a new tool called RV-Explorer (Rdf View eXplorer) which implements several navigational modes. However, this navigation/exploration reveal several incompletions in the data sets. In order to complete the data, we use association rule mining for completing RDF data. Furthermore, for providing navigation and exploration directly over RDF graphs along with background knowledge, RDF triples are clustered w.r.t. background knowledge and these clusters can then be navigated and interactively explored. Finally, it can be concluded that instead of providing direct exploration we use FCA as an aid for clustering RDF data and allow user to explore these clusters of data and enable the user to reduce his exploration space by interaction

Texto completo da fonteIt was in the 70s when the interest for robotics really emerged. It was barely half a century ago, and since then robots have been replacing humans in the industry. This robot-oriented solution doesn't come without drawbacks as full automation requires time-consuming programming as well as rigid environments. With the increased need for adaptability and reusability of assembly systems, robotics is undergoing major changes and see the emergence of a new type of collaboration between humans and robots. Human-Robot collaboration get the best of both world by combining the respective strengths of humans and robots. But, to include the human as an active agent in these new collaborative workspaces, safe and flexible robots are required. It is in this context that we can apprehend the crucial role of motion generation in tomorrow's robotics. For the emergence of human-robot cooperation, robots have to generate motions ensuring the safety of humans, both physical and physchological. For this reason motion generation has been a restricting factor to the growth of robotics in the past. Trajectories are excellent candidates in the making of desirable motions designed for collaborative robots, because they allow to simply and precisely describe the motions. Smooth trajectories are well known to provide safe motions with good ergonomic properties. In this thesis we propose an Online Trajectory Generation algorithm based on sequences of segment of third degree polynomial functions to build smooth trajectories. These trajectories are built from arbitrary initial and final conditions, a requirement for robots to be able to react instantaneously to unforeseen events. Our approach built on a constrained-jerk model offers performance-oriented solutions : the trajectories are time-optimal under safety constraints. These safety constraints are kinematic constraints that are task and context dependent and must be specified. To guide the choice of these constraints we investigated the role of kinematics in the definition of ergonomics properties of motions. We also extended our algorithm to cope with non-admissible initial configurations, opening the way to trajectory generation under non-constant motion constraints. [...]

Texto completo da fonteThe goal of Interactive Molecular Simulations (IMS) is to observe the conformational dynamics of a molecular simulation in real-time. Instant visual feedback enables informative monitoring and observation of structural changes imposed by the user's manipulation of the IMS. I conducted an in-depth study of knowledge to gather and synthesize all the research that has developed IMS. Interactive Molecular Dynamics (IMD) is one of the first IMS protocols that laid the foundation for the development of this approach. My thesis laboratory was inspired by IMD to develop the BioSpring simulation engine based on the elastic network model. This model allows for the simulation of the flexibility of large biomolecular ensembles, potentially revealing long-timescale changes that would not be easily captured by molecular dynamics. This simulation engine, along with the UnityMol visualization software, developed through the Unity3D game engine, and linked by the MDDriver communication interface, has been extended to converge towards a complete software suite. The goal is to provide an experimenter, whether an expert or novice, with a complete toolbox for modeling, displaying, and interactively controlling all parameters of a simulation. The particular implementation of such a protocol, based on formalized and extensible communication between the different components, was designed to easily integrate new possibilities for interactive manipulation and sets of experimental data that will be added to the restraints imposed on the simulation. Therefore, the user can manipulate the molecule of interest under the control of biophysical properties integrated into the simulated model, while also having the ability to dynamically adjust simulation parameters. Furthermore, one of the initial objectives of this thesis was to integrate the management of ambiguous interaction constraints from the HADDOCK biomolecular docking software directly into UnityMol, making it possible to use these same restraints with a variety of simulation engines. A primary focus of this research was to develop a fast and interactive protein positioning algorithm in implicit membranes using a model called the Integrative Membrane Protein and Lipid Association Method (IMPALA), developed by Robert Brasseur's team in 1998. The first step was to conduct an in-depth search of the conditions under which the experiments were performed at the time to verify the method and validate our own implementation. We will see that this opens up interesting questions about how scientific experiments can be reproduced. The final step that concluded this thesis was the development of a new universal lipid-protein interaction method, UNILIPID, which is an interactive protein incorporation model in implicit membranes. It is independent of the representation scale and can be applied at the all-atom, coarse-grain, or grain-by-grain level. The latest Martini3 representation, as well as a Monte Carlo sampling method and rigid body dynamics simulation, have been specially integrated into the method, in addition to various system preparation tools. Furthermore, UNILIPID is a versatile approach that precisely reproduces experimental hydrophobicity terms for each amino acid. In addition to simple implicit membranes, I will describe an analytical implementation of double membranes as well as a generalization to arbitrarily shaped membranes, both of which rely on novel applications

Texto completo da fonteIn this thesis, we present the problem of the visual data mining. We generally notice that it is specific to the types of data and that it is necessary to spend a long time to analyze the results in order to obtain an answer on the aspect of data. In this thesis, we have developed an interactive visualization environment for data exploration using points of interest. This tool visualizes all types of data and is generic because it uses only one similarity measure. These methods must be able to deal with large data sets. We also sought to improve the performances of our visualization algorithms, thus we managed to represent one million data. We also extended our tool to the data clustering. Most existing data clustering methods work in an automatic way, the user is not implied iin the process. We try to involve more significantly the user role in the data clustering process in order to improve his comprehensibility of the data results

Texto completo da fonteThe growing importance given today to personalized contents led to the development of several interactive classification systems for various novel applications. Nevertheless, all these systems use a single-label item classification which greatly constrains the user's expressiveness. The major problem common to all developers of an interactive multi-label system is: which multi-label classifier should we choose? Experimental evaluations of recent interactive learning systems are mainly subjective. The importance of their conclusions is consequently limited. To draw more general conclusions for guiding the selection of a suitable learning algorithm during the development of such a system, we extensively study the impact of the major interactivity constraints (learning from few examples in a limited time) on the classifier predictive and time-computation performances. The experiments demonstrate the potential of an ensemble learning approach Random Forest of Predictive Clustering Trees(RF-PCT). However,the strong constraint imposed by the interactivity on the computation time has led us to propose a new hybrid learning approach FMDI-RF+ which associates RF-PCT with an efficient matrix factorization approach for dimensionality reduction. The experimental results indicate that RF-FMDI+ is as accurate as RF-PCT in the predictions with a significant advantage to FMDI-RF + for the speed of computation

Texto completo da fonteRobot-assisted surgery, or “robotic”surgery, has been developed to address thedifficulties with the traditional laparoscopicsurgery. The da Vinci (Intuitive Surgical, CA andUSA) is one of the FDA-approved surgical robotic system which is widely used in the case of abdominal surgeries like hysterectomy and cholecystectomy. The technology includes a system of master and slave tele-manipulators that enhances manipulation precision. However, inadequate guidelines and lack of a human machine interface system for planning the ports on the abdomen surface are some of the main issues with robotic surgery. Unreachable target and mid-surgery collisions between robotic arms are the major problems that surgeons complain about in robotic surgery. The objective of this research is to design a new decision-support tool for planning port placement in robotic surgery. The decision support system will be able to determine the optimal location of the entrance ports on the abdomen surface that is specific to the patient

The PDE method treats surface design as a boundary-value problem and ensures that surfaces can be defined using an appropriately chosen set of boundary conditions and design parameters. Here we show how the data input to the system, from a user interface such as the mouse of a computer terminal, can be efficiently used to define a set of parameters with which to manipulate the surface interactively in real time.

Texto completo da fonteEnergy efficiencies are became a major issue. Building from any country have been identified as gap of energy, building are not enough insulated and energy loss by this struc- ture represent a major part of energy expenditure. RIDER has emerged from this viewpoint, RIDER for Research for IT Driven EneRgy efficiency. This project has goal to develop a new kind of IT system to optimize energy consumption of buildings. This system is based on a component paradigm, which is composed by a pivot model, a data warehouse with a data mining approach and a visualization tool. These two last components are developed to improve content of pivot model.In this manuscript, our focus was on the visualization part of the project. This manuscript is composed in two parts: state of the arts and contributions. Basic notions, a visualization chapter and a visual analytics chapter compose the state of the art. In the contribution part, we present data model used in this project, visualization proposed and we conclude with two experimentations on real data

Texto completo da fonteWith the fast increase in computing power, numerical simulations of physical phenomena can nowadays rely on up to billions of elements. To extract relevant information in the huge resulting data sets, engineers need visualization tools permitting an interactive exploration and analysis of the computed fields. The goal of this thesis is to improve the visualizations performed by engineers by taking into account the characteristics of the human visual perception, with a particular focus on the perception of space and volume during the visualization of dense 3D data. Firstly, three psychophysics experiments have shown that direct volume rendering, a technique relying on the ordered accumulation of transparencies, provide very ambiguous cues to depth. This is particularly true for static presentations, while the addition of motion and exaggerated perspective cues help to solve part of these difficulties. Then, two algorithms have been developed to improve depth perception during the visualization of complex 3D structures. They have been implemented on the GPU, to achieve interactive renderings independently of the geometric nature of the analysed data. EyeDome Lighting is a new non-photorealistic shading technique that relies on the projected depth image of the scene. This algorithm enhances the perception of shapes and relative depths in complex 3D scenes. Also, a new fast view-dependent cutaway technique has been implemented, which permits to access otherwise occluded objects while providing cues to understand the structure in depth of masking objects

Texto completo da fonteData Warehouses (DWs) become essential components for companies and organizations.DWdesign field has been actively researched in recent years. The main limitation of the proposedapproaches is the lack of an overall vision covering the DW design cycle. Our main contributionin this thesis is to propose a method adapted to recent evolutions of the DW design cycle,and covering all its phases. These evolutions have given rise to new data storage models andnew deployment architectures, which offers different design choices for designers and administrators.DW literature recognizes the importance of user requirements in the design process, andthe importance of accessing and representing data semantics. We propose an ontology drivendesign method that valorizes users’ requirements by providing them a persistent view in theDW structure. This view allows anticipating diverse design tasks and simulating different designchoices. Our second proposal revisits the design cycle by executing the ETL phase (extractiontransformation-loading of data) in the conceptual stage. This proposal allows a deployment à lacarte of the DW using the different deployment platforms available

Texto completo da fonteThis thesis deals with LVIS, a visual query language for spatiotemporal databases and more specifically for Geographical Information Systems (GIS). The language follows a query-by-example philosophy. Visual representations of queries - or visual queries - are incrementally specified by means of two sets of icons: the first one contains the icons that represent the object types of the database to be queried; the second one contains the icons of a minimal set of operators that are useful to express some criteria. Visual queries are then translated into a intermediate textual language - named pivot language. This pivot language is independent of the GIS that will finally execute queries. The language is defined by three independent grammars. A first grammar defines the semantics of the language. The second grammar - or visual grammar - defines the visual semantics of the language. The last grammar defines the keywords of the pivot language and allows the queries to be translated into the query language of a GIS that is chosen by the end user. A prototype has been developed with the aim of testing the interactions of the language with the MapInfo GIS. The two main contributions in the field of visual querying are: (1) The formulation of spatiotemporal queries are handled by both the integration of temporal (Allen relationships) and spatiotemporal (life-cycle of objects) operators and the definition of new visual metaphors allowing to visually represent such queries. (2) The validation of the icons of the language is assumed by psycho-cognitive tests that have been subjected to potential users. These tests aim too at evaluating the user-friendliness of the language
