End-User Development in Ambient Intelligence: a User Study
No full textIn this paper we propose a novel conceptual framework for the design and continuous evolution of ambient intelligence environments. This framework is structured along three layers - physical, inference and user layer - sharing an information space of events, conditions and actions. In particular, an end-user development approach is advocated for the user layer to support rule design and development. At this stage of the research agenda, we are investigating which could be the most suitable interaction style for rule design: indeed, it should be compatible with the underlying distributed inference layer and easy to use by a community of end users (e.g. a family). To this aim, this paper presents a user study that explores end-user development tasks for a smart home and compares two well-known systems in supporting end users in these activities. The results of the study have provided some indications for the further implementation of our framework
Designing Human-Robot Collaboration for the Preparation of Personalized Medicines
Full text linkAdvancements in robotics and automation technologies have the potential to enable breakthrough innovations in a variety of industries, and the pharmaceutical sector is no exception. The preparation of galenic formulations, involving the compounding and dispensing of medications, when personalized medicines are needed, e.g., to overcome allergy problems, is a critical process in the field of small scale pharmaceutical manufacturing. Traditionally, this process has relied solely on human expertise of pharmacists and their manual labor, which can be time-consuming, prone to errors, and subject to variations in quality. To overcome these limitations, the use of collaborative robots is envisaged in our project. A collaborative robot can in fact work with the pharmacist synergistically, by improving accuracy and increasing productivity. However, the main challenge is providing the pharmacists with an interactive system that supports them in robot programming. In this paper, we analyze the
problem from the users’ point of view and propose preliminary lowfidelity prototypes of an interactive system suitable to pharmacists’ needs and skills
A Hand Gesture Interface Using Hand Shapes and Dynamic Hand Movement: the Home Control Case
No full textOur hand-based gestural interaction system (called HANDY)
is able to recognize the hand shapes and dynamic hand
movements of the user. Such gestural interaction system
can be exploited in various applications. In this work we
consider a domotic application for central control of home
devices. Actions are represented as gestures composed of
a sequence/combination of hand shapes and dynamic hand
movements, modeled by state machines
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
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
