    Edition synchrone de plusieurs objets : services et interaction

    International audienceGraphical interactions that modify many objects at once have not been studied systematically. Based on contextual inquiries of designers, and on previous systems and work, we have identified the services required for an efficient interaction with multiple objects: set management, action management, and support for exploratory design. We present a number of interactions that provide a subset of the identified services, by relying on an improved property sheet. This work may enable designers to design more consistent and more powerful interactions

    Supporting both exploratory design and power of action with a new property sheet

    Graphical interaction designers often make tradeoffs between supporting exploratory design and power of action. In this paper, we describe a new property sheet and a set of interaction that aims at supporting both. Thanks to a new visualization of properties and values, and modeless, example-based interaction and selection, designers can make an opportunistic use of implicit groups to augment their power of action

    Augmenting the scope of interactions with implicit and explicit graphical structures

    International audienceWhen using interactive graphical tools, users often have to manage a structure, i.e. the arrangement of and relations between the parts or elements of the content. However, the interaction with structures may be complex, and not well integrated with the interaction with the content. Based on contextual inquiries and past works, we have identified a number of concepts and requirements about the interaction with structure. We have explored two interactive tools: a new kind of property sheet that relies on the implicit struc-ture of graphics; and a property delegation graph to enable users to provide an explicit graphical structure. The interac-tions with the tools augment the scope of interactions to multiple objects

    National audienceNous présentons dans l' article le résultat d'un travail réalisé à l'école de Printemps 2010 de l'AFIHM. L'analyse des activités liées à la réalisation d' un état de l'art nous montre qu'une des tâches les plus compliquées est la familiarisation avec un nouveau domaine. Pour outiller cette activité, nous présentons des pistes de réflexion basées sur une analogie avec la mémoire humaine

    Interaction et Visualisation avec des liens de dépendances

    Although many interactive tools allows manipulating effectively objects individually by applying principles such as direct manipulation, interaction with multiple objects have been little studied so far. Our thesis is that it is important to design interactions for the synchronous operation of multiple objects that are efficient, while fostering exploratory design. From contextual inquiries, we describe an analysis of needs which established a set of requirements for interactions on sets. We present four interactive tools to illustrate concepts of interaction with structures: links delegation, which are based on the delegation mechanism in prototype languages, allowing to establish dependencies between objects (and create clones) and extend the scope of interactions by propagating them; ManySpector, a new type of property inspector that reveals an implicit structuring of a scene and allows for building, with instrumental interactions, graphical query and selection; IHR, a tool that can automatically create a hierarchy of delegated properties; and Histoglass a movable lens that allows to locally manipulate the properties and past user actions. We also present the results of evaluations conducted with users in order to measure interest in the concepts provided by the tools developed. All of this work has led us to the draft of a new interaction paradigm, "the structural interaction", which extends the paradigms of direct manipulation and instrumental interaction.De nombreux outils interactifs permettent de manipuler efficacement des objets individuellement en appliquant notamment les principes de la manipulation directe. Les interactions avec de multiples objets quant à elles n'ont été que peu étudiées. Notre thèse est qu'il est important de concevoir des interactions permettant la manipulation synchrone d'objets multiples qui soient efficaces, tout en favorisant la conception exploratoire. A partir d'enquêtes menées en contexte, nous décrivons une analyse de besoins ayant permis d'établir un ensemble d'exigences relatives aux interactions sur les ensembles. Nous présentons quatre outils interactifs qui illustrent des concepts d'interaction sur des structures : les liens de délégation, qui s'inspirent du mécanisme de délégation des langages à prototypes en permettant d'établir explicitement des dépendances entre objets (et de créer des clones) et d'étendre la portée des interactions en les propageant ; ManySpector, un nouveau type d'inspecteur de propriétés qui révèle une structuration implicite d'une scène et qui permet de construire, par des interactions instrumentales, des requêtes graphiques et de sélection ; IHR, un outil pouvant créer automatiquement une hiérarchie de propriétés déléguées ; et Histoglass, une lentille déplaçable qui permet de réutiliser localement les propriétés et les actions passées de l'utilisateur. Nous présentons par ailleurs les résultats d'évaluations menées auprès d'utilisateurs afin de mesurer l'intérêt des concepts apportés par les outils conçus. L'ensemble de ce travail nous a conduit à l'ébauche d'un nouveau paradigme d'interaction : " l'interaction structurelle ", qui étend les paradigmes de la manipulation directe et de l'interaction instrumentale

    Genetic diagnosis of primary immunodeficiencies: A survey of the French national registry

    No full text
    International audienceTo the Editor:Since the mid-1980s, continuous progress in genetics and genomics has accelerated the rapid identification of causative genetic variants leading to primary immunodeficiencies (PIDs; >300 genes),1 with the noticeable exception of B-cell disorders, such as common variable immunodeficiency (CVID). The identification of these mutations not only validates a clinical diagnosis but also is useful in several other respects (more accurate prognosis on phenotype/genotype correlation, targeted therapy, and genetic counseling).
