On the discursive self-construction of expats, behavior and values
2018
Considering that learners engage in the creation of new educational scenarios, often using digital media, travelogues have been analysed because they represent the digital development of a well-established genre within tourism discourse. This study focuses on the discursive construction of expats as 1) integrated tourist and 2) travelogue writers. I consider the occurrence of an Us as opposed/assimilated with a Them in the expression of values, behaviors and spaces by analyzing a corpus made up of articles taken from the most accessed travel webzines for expats at the time of the research. Then I analyse the thematic structures and techniques of this textual typology. The paper may help to …
Scritti in onore di Pellegrino Capaldo
2014
La qualità dei servizi è stata riconosciuta come un rilevante aspetto caratterizzante la performance dell’azienda pubblica, analogamente alla capacità di operare secondo criteri di efficienza e nel rispetto dei vincoli di bilancio. Sebbene sia possibile riscontrare alcuni significativi casi di adozione di politiche di customer satisfaction nelle amministrazioni pubbliche italiane, a tutt’oggi il tema presenta significative criticità, specialmente in ordine agli aspetti metodologici e agli strumenti operativi che consentano di integrare dette politiche nel sistema di programmazione e controllo delle aziende che erogano tali servizi. Il presente lavoro adotta una diversa prospettiva di analis…
User Psychology in Interaction Design: The Role of Design Ontologies
2008
In the various forms of interaction design, it is essential to analyze, understand, and predict human behavior. This is equally true with devices such as information systems that are meant to interact with people. The importance of these problems has inspired scientists to develop numerous approaches to investigate and explicate human actions. However, they have mainly been characterized by intuitive and folk psychological approaches to the human mentality in interaction. To improve the scientific foundations of design, we present here a psychology-based approach to collecting user knowledge, as well as a related design practice. The former can be called user psychology and the latter the a…
BioLab: An Educational Tool for Signal Processing Training in Biomedical Engineering
2007
This paper introduces and evaluates BioLab, a tool for teaching biosignal processing. BioLab has been used in the biomedical engineering module that is given in the second semester of the fifth year of the electronic engineering degree at the University of Valencia, Spain. This module and its correspondent curricular pathway are also reviewed. BioLab allows the results obtained with digital processing techniques to be shown interactively in the theory classes, and it also provides support in laboratory sessions. The graphic interface of BioLab simplifies its learning and use and provides access to processing and visualization functions by means of menus. The tool is based on Matlab since th…
P300-based brain computer interface experimental setup
2009
A Brain-Computer interface (BCI) is a communication system that enables the generation of a control signal from brain signals such as sensorymotor rhythms and evoked potentials; therefore, it constitutes a novel communication option for people with severe motor disabilities (such as Amyotrophic Lateral Sclerosis patients). This paper presents the development of a P300-based BCI. This prototype uses a homemade six-channel electroencephalograph for the acquisition of the signals, and a visual stimulation matrix; since this matrix contains letters of the alphabet as well as images associated to them, it permits word-writing and the elaboration of messages with the images. To process the signal…
Sputtered SiOxNy thin films: improving optical efficiency of liquid crystal diffuser elements in multi-focal near-to-eye display architecture
2021
In this work we present reactive sputtered SiOxNy films with a variable refractive index as a convienent solution for contrast improvement of liquid crystal diffuser multi stacks in near-to-eye AR/VR displays. The focus concerns minimization of light reflections between internal structures, in particular ITO, by optimizing internal layers through tailored properties of thin film coatings, as well as subsequent laser patterning of thin film stack. Inorganic thin films have been deposited on glass by physical vapor deposition. Corresponding refractive index, thickness, uniformity and dielectric characteristics and other electro-optical properties have been measured and their impact on the res…
Optimisation des requêtes de similarité dans les espaces métriques répondant aux besoins des usagers
2012
The complexity of data stored in large databases has increased at very fast paces. Hence, operations more elaborated than traditional queries are essential in order to extract all required information from the database. Therefore, the interest of the database community in similarity search has increased significantly. Two of the well-known types of similarity search are the Range (Rq) and the k-Nearest Neighbor (kNNq) queries, which, as any of the traditional ones, can be sped up by indexing structures of the Database Management System (DBMS). Another way of speeding up queries is to perform query optimization. In this process, metrics about data are collected and employed to adjust the par…
More years, more technologies : aging in the digital era
2018
This special issue presents research on the role of digital health and communication technologies in later life. Drawing from the observation that people’s longer lives are affected by digital technologies to varying extents and recognizing the vast supply of traditional and digital technologies targeted at older users, we maintain that the principle of aged heterogeneity also manifests itself with respect to the adoption and use of digital technologies. Basing on the findings presented in the articles of the issue, we conclude n this introduction to the issue that the concept of aged heterogeneity and the particularities of old age as a stage of life are still insufficiently incorporated i…
DETECTING FALLS AT HOME: USER-CENTERED DESIGN OF A PERVASIVE TECHNOLOGY
2016
Falling is the main cause of domestic accidents and fatal injuries to seniors at home. In this paper, we describe the design process for a new pervasive technology (CIRDO). The aim of this technology is to detect falls (via audio and video sensors) and to alert the elderly's family or caregivers. Two complementary studies were performed. Firstly, the actual risk situations of older adults were analyzed. Secondly, social acceptance was investigated for the different homecare field stakeholders. Our results highlight the tensions among social actors towards the tool and their impacts on technology acceptance by the elderly. Also, we show a significant change in the fall process due to the dev…
Human Technology : Toward the Second Decade
2015
The inaugural issue of Human Technology: An Interdisciplinary Journal on Humans in ICT Environments was published in 2005. The 10 volumes of two to three issues comprise well over 2000 pages. Upon starting as editor in chief in January 2015, I browsed through the archives and noticed that just over 100 articles had been published in the journal. Examining these titles, it is evident that they address a wide variety of topics. Nevertheless, four broad themes emerge: The user of technology, with such foci as user experience, user characteristics, usability, user interface, and, on a more theoretical level, cognition; The learner in a technological environment, covering aspects such as inf…
