Distributable Interface Design for Web Applications
No full textThe increasing number of devices available for each person allows to create unconventional interfaces that coordinate more than one device for supporting the interaction. In this paper, we introduce a framework for designing distributable web applications, which supports moving and sharing the different parts of a user interface across different devices. We depict the architectural solution and we introduce a set of distribution patterns. In addition, we describe a concrete application of the framework for a distributable video player application
Developing Touchless Interfaces with GestIT
No full textThis article presents a solution for supporting adaptive user interfaces
in work environments. Its architecture is built upon the concept of model-based
UI design extended by context aware and adaptive features. Model-based
languages provide the software development process with useful support for,
building design prototypes and actual implementations for devices with various
interaction resources. The proposed architecture is able to adapt to selected
aspects of the context during run-time by communicating with a context server
and applying the specified adaptation rules. In order to show the possibilities of
the proposed solution, we report on its application in the development of an
adaptive user interface prototype to be used in a warehouse picking system
Immersiveness of ubiquitous computing environments prototypes: A case study
Full text linkThe development of ubiquitous computing (ubicomp) environments raises several challenges in terms of their evaluation. Ubicomp virtual reality prototyping tools enable users to experience the system to be developed and are of great help to face those challenges, as they support developers in assessing the consequences of a design decision in the early phases of development. Given the situated nature of ubicomp environments, a particular issue to consider is the level of realism provided by the prototypes. This work presents a case study where two ubicomp prototypes, featuring different levels of immersion (desktop-based versus CAVE-based), were developed and compared. The goal was to determine the cost/benefits relation of both solutions, which provided better user experience results, and whether or not simpler solutions provide the same user experience results as more elaborate one.info:eu-repo/semantics/acceptedVersio

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
Adaptive User Interfaces for Smart Environments with the Support of Model-Based Languages
No full textIn this paper, we report on the development of touchless interfaces
for supporting long lasting tasks, which need an interleaving between the interaction
with the system and the focus on other activities. As an example, we
considered a dish cooking task, which enables selecting and browsing the information
about different recipes while cooking through gestural and vocal interaction.
The application demonstrates the advantages offered by the GestIT library,
which allows a declarative and compositional definition of reusable gesture
Co-design Practice in a Smart City Context Through the Gamification Approach: A Survey About the Most Suitable Applications
No full textIn a “smart” city context, citizens’ participation allows to create public services and products meeting the real people’s needs. In this regard, the co-design process is a useful practice for encouraging city users to co-create new effective solutions. However, it is fundamental to renovate methodologies and tools for citizens’ engagement. In this paper, we argue that the gamification approach could increase the willingness of city users in getting involved in Public Administration (PA) decision-making processes and in co-design practices. Assuming that, we present the main findings of a survey conducted to investigate city users’ behaviours and needs on gamification and co-design issues. These findings will be useful to identify the most suitable applications combining these two practices
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
