Sortilegios y prodigios como antídotos de realidad. Todo es posible en Granada
2011
La película Todo es posible en Granada (José Luis Sáenz de Heredia, 1954) narra en clave de comedia fantástica un relato que transcurre a medidos los años cincuenta del pasado siglo en el contexto de los acuerdos bilaterales entre España y Estados Unidos, dando cuenta de las diferencias interculturales existentes entre la sociedad española, aferrada a sus tradiciones, y los visitantes extranjeros que sólo desean confirmar los prejuicios y estereotipos que alberga su imaginario sobre el país. Así, desde una envoltura formal impecable, se construye un discurso que ajusta sus premisas al ideario oficial del régimen, pero alejado de la realidad concreta y trufado de numerosas contradicciones. T…
Towards Ethical Guidelines of Using Telepresence Robots in Residential Care
2021
AbstractRobotic telepresence is a potential technology to help alleviating the loneliness of elderly people. The impacts of long-term use of telepresence robots in residential care are not well known. We were interested in how using a telepresence robot influences the resident, family members and care workers at a facility, and what challenges and solutions there are for wider adoption of such robots in residential care. With a telepresence robot Double, we arranged a series of three trials in two separate residential care facilities: one 12-week trial in a private facility and two successive 6-week trials in a public facility. In each trial, we installed the telepresence robot in a room of…
Revista electrónica de investigación y evaluación educativa
2017
Resumen basado en el de la publicación Título, resumen y palabras clave en español e inglés Disponible la versión en inglés El objetivo es analizar el proyecto de nuevo cuestionario diseñado por la Universidad del País Vasco (UPV/EHU) para realizar la evaluación de sus docentes (SET). Se analizan las respuestas de una muestra de 941 estudiantes y se estudia la fiabilidad del cuestionario, la dimensionalidad, la validez de constructo y criterial, finalizando con un estudio diferencial tomando en cuenta variables como el género, el campo disciplinar, el nivel percibido de dificultad o el interés de las materias. Los resultados permiten afirmar que se trata de un instrumento de alta consistenc…
Movement Detection with Event-Based Cameras: Comparison with Frame-Based Cameras in Robot Object Tracking Using Powerlink Communication
2018
Event-based cameras are not common in industrial applications despite the fact that they can add multiple advantages for applications with moving objects. In comparison with frame-based cameras, the amount of generated data is very low while keeping the main information in the scene. For an industrial environment with interconnected systems, data reduction becomes very important to avoid network congestion and provide faster response time. However, the use of new sensors as event-based cameras is not common since they do not usually provide connectivity to industrial buses. This work develops a network node based on a Field Programmable Gate Array (FPGA), including data acquisition and trac…
Balanced Large Scale Knowledge Matching Using LSH Forest
2015
Evolving Knowledge Ecosystems were proposed recently to approach the Big Data challenge, following the hypothesis that knowledge evolves in a way similar to biological systems. Therefore, the inner working of the knowledge ecosystem can be spotted from natural evolution. An evolving knowledge ecosystem consists of Knowledge Organisms, which form a representation of the knowledge, and the environment in which they reside. The environment consists of contexts, which are composed of so-called knowledge tokens. These tokens are ontological fragments extracted from information tokens, in turn, which originate from the streams of information flowing into the ecosystem. In this article we investig…
Overview of ghost correction for HDR video stream generation
2015
International audience; Most digital cameras use low dynamic range image sensors, these LDR sensors can capture only a limited luminance dynamic range of the scene[1], to about two orders of magnitude (about 256 to 1024 levels). However, the dynamic range of real-world scenes varies over several orders of magnitude (10.000 levels). To overcome this limitation, several methods exist for creating high dynamic range (HDR) image (expensive method uses dedicated HDR image sensor and low-cost solutions using a conventional LDR image sensor). Large number of low-cost solutions applies a temporal exposure bracketing. The HDR image may be constructed with a HDR standard method (an additional step ca…
Progetto professionale e soft skills negli studenti liceali
2020
In questo contributo si descrivono, in primo luogo, le metodologie educative utilizzate in alcune ricerche italiane negli ultimi venti anni per aiutare gli studenti del liceo a costruire il loro progetto di vita formativo-professionale; in secondo luogo, si presentano le fasi e i risultati della prima parte di una ricerca-intervento sull’orientamento dal liceo all’università svolta nella città di Palermo nell’anno scolastico 2018-2019; in terzo luogo, si espongono le tre attività formative (sessioni di scrittura espressiva, colloqui di orientamento e laboratori interdisciplinari Scuola-Università) previste durante la seconda annualità per consentire ai liceali di saggiare i loro interessi d…
Experiences from the Use of an Eye-Tracking System in the Wild
2010
Eye-tracking systems have been widely used as a data collection method in the human–computer interaction research field. Eyetracking has typically been applied in stationary environments to evaluate the usability of desktop applications. In the mobile context, user studies with eye-tracking are far more infrequent. In this paper, we report our findings from user tests performed with an eye-tracking system in a forest environment. We present some of the most relevant issues that should be considered when planning a mobile study in the wild using eye-tracking as a data collection method. One of the most challenging finding was the difficulty in identifying where the user actually looked in th…
