No full textInteraction with large displays: a survey
Full text linkLarge interactive displays are increasingly placed in public (or semi-public) locations, including museums, shops, various city settings and offices. This article discusses the evolution of such displays by looking at their use and analyzing how they are changing the concept of human-computer interaction through new modalities. By surveying the literature on systems using these displays, relevant features were identified and used as classification dimensions. The analysis provided may inform the design and development of future installations. A discussion on research challenges concludes the article
European-American Collaboration Workshop
No full textDifferent researchers have focused on complementary aspects of end-user development. For example, some people work on tool-building while others explore different models for participatory programming. This workshop will focus discussion on identifying opportunities for collaboration, particularly between European and American research groups. Submitted position papers have revealed three topics that could be used to frame collaborative projects. At the workshop, participants will meet one another, discuss how to pursue collaboration, and explore avenues for obtaining funding to support international collaboration
End-user composition of interactive applications through actionable UI components
Full text linkDeveloping interactive systems to access and manipulate data is a very tough task. In particular, the development of user interfaces (UIs) is one of the most time-consuming activities in the software lifecycle. This is even more demanding when data have to be retrieved by accessing flexibly different online resources. Indeed, software development is moving more and more toward composite applications that aggregate on the fly specific Web services and APIs. In this article, we present a mashup model that describes the integration, at the presentation layer, of UI components. The goal is to allow non-technical end users to visualize and manipulate (i.e., to perform actions on) the data displayed by the components, which thus become actionable UI components. This article shows how the model has guided the development of a mashup platform through which non-technical end users can create component-based interactive workspaces via the aggregation and manipulation of data fetched from distributed online resources. Due to the abundance of online data sources, facilitating the creation of such interactive workspaces is a very relevant need that emerges in different contexts. A utilization study has been performed in order to assess the benefits of the proposed model and of the Actionable UI Components; participants were required to perform real tasks using the mashup platform. The study results are reported and discussed
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Supporting professional guides to create personalized visit experiences
No full textInformation and communication technologies have a great potential to enhance personal experience in cultural heritage sites. Our research in the Cultural Heritage (CH) aims to foster a wider appreciation of archaeology by offering tools able to engage the general public and to increase awareness of the importance of CH. In this paper we discuss how a generic mashup platform can be used to support the work of professional guides of CH sites, in order to support them creating personalized and engaging visit experiences
Distributing the User Interface Logics along Actionable Components: the EFESTO Approach
No full textDeveloping interactive systems is a very tough task. In particular, the development of user interfaces (UIs) is one of the most time consuming aspects in the software lifecycle. Software development is more and more moving toward composite applications. In this paper, we present a mashup model that enables the integration at the presentation layer of specific UI components. As application of this model, a mashup platform has been developed that allows non-technical end users to create component-based interactive workspaces via the aggregation and manipulation of data fetched from distributed online resources, also enabling the collaborative creation and use of distributed interactive workspaces. It is shown in this paper how the developed platform permits the rapid prototyping of interactive applications enabling the access to Web services and APIs
A three-layer meta-design model for addressing domain-specific customizations
No full textMeta-design has been proposed as a model to design systems able to support End-User Development (EUD). Meta-design means "design for designers." Differently than in traditional design, professional developers do not directly create a final application, but they build software environments thorough which non-technical end users, acting as co-designers, are enabled to shape up the application while they are using it. Allowing end users to participate to the creation of their applications, by modifying or even creating from scratch software artifacts, is very challenging. To make this possible, end users have to be provided with software environments customized to their specific domain, which they can easily understand and use. In order to cope with domain specificity, this chapter presents a new meta-designmodel that specifically addresses the customization to a domain of interest. Customization, performed by domain experts possibly in collaboration with professional developers, becomes the key activity to provide non-technical end users with software environments that are adequate to their knowledge and needs, thus allowing them to actually become co-designers of their applications. The model is illustrated by describing its successful application to the design of a mashup platform that allows end users to create new applications by integrating data and functionality taken from different resources. The customization of the platform to different domains, such as CulturalHeritage and Technology Enhanced Learning, is discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
