López Ribalda y otros vs. España [2018]. La violación al derecho a la privacidad a partir de la videovigilancia oculta

2020

En el presente capítulo se analiza el caso López Ribalda vs. España, resuelto por el Tribunal Europeo de Derechos Humanos, en el cual se planteó la legitimidad de usar la videovigilancia oculta en una instalación comercial como herramienta para identificar a las personas responsables del delito de robo. Esta situación pone de manifiesto un conflicto de intereses entre quienes ven disminuido su derecho a la privacidad y quien intenta proteger su patrimonio mediante la instalación de un sistema de vigilancia oculto.

Análisis del papel de los maestros en el desarrollo de actividades de indagación en el practicum de primaria

2014

Resumen En este trabajo se examina el papel que juegan tres maestros en practicas en la aplicacion de actividades de indagacion en Primaria y como influye en su desarrollo. Para ello se analizan las grabaciones en video de estos docentes durante una actividad desarrollada en su practicum,  utilizando un sistema de categorias que tiene en cuenta: las fases didacticas como observacion o planteamiento de hipotesis,  las habilidades comunicativas como descripcion o preguntas, y quien realiza la accion (maestro o alumno). Los resultados muestran que los maestros en practicas encuentran dificultades ligadas a aspectos de: 1) estructuracion de las secuencias didacticas; 2) planteamiento de pregunt…

A real-time non-intrusive FPGA-based drowsiness detection system

2011

Automotive has gained several benefits from the Ambient Intelligent researches involving the deployment of sensors and hardware devices into an intelligent environment surrounding people, meeting users’ requirements and anticipating their needs. One of the main topics in automotive is to anticipate driver needs and safety, in terms of preventing critical and dangerous events. Considering the high number of caused accidents, one of the most relevant dangerous events affecting driver and passengers safety is driver’s drowsiness and hypovigilance. This paper presents a low-intrusive, real-time driver’s drowsiness detection system for common vehicles. The proposed system exploits the ‘‘bright p…

E-learning in radiology: an Italian multicentre experience.

2012

Objective: The aim of this study was to design, deliver and evaluate an e-learning teaching programme for post-graduate radiodiagnostics training that would involve various post-graduate schools throughout Italy. Materials and methods: All of the Directors of Italian post-graduate schools of radiodiagnostics were sent an e-mail on 27 September 2010 informing them of our willingness to set up an e-learning project for the academic year 2010-2011 in the form of single-subject teaching seminars. The proposed subjects were the semeiotics of the various organs and apparatuses in the context of "Urgent/Emergency Pathology". After having received registrations, a calendar of lessons was planned to…

Educational value of surgical videos on YouTube: quality assessment of laparoscopic appendectomy videos by senior surgeons vs. novice trainees

2019

Background To prepare for surgery, surgeons often recur to surgical videos, with YouTube being reported as the preferred source. This study aimed to compare the evaluation of three surgical trainees and three senior surgeons of the 25 most viewed laparoscopic appendectomy videos listed on YouTube. Additionally, we assessed the video conformity to the published guidelines on how to report laparoscopic surgery videos (LAP-VEGaS). Methods Based on the number of visualization, the 25 most viewed videos on laparoscopic appendectomy uploaded on YouTube between 2010 and 2018 were selected. Videos were evaluated on the surgical technical performance (GOALS score), critical view of safety (CVS), and…

Making interaction with virtual reality accessible : rendering and guiding methods for subtitles

2021

AbstractAccessibility in immersive media is a relevant research topic, still in its infancy. This article explores the appropriateness of two rendering modes (fixed-positioned and always-visible) and two guiding methods (arrows and auto-positioning) for subtitles in 360° video. All considered conditions have been implemented and integrated in an end-to-end platform (from production to consumption) for their validation and evaluation. A pilot study with end users has been conducted with the goals of determining the preferred options by users, the options that result in a higher presence, and of gathering extra valuable feedback from the end users. The obtained results reflect that, for the c…

The Quest for Global Safety

2007

The authors present a systematic study on the factors that have influence on the establishment of the safety conditions ensuring the rise of Global Earthing Systems. Starting from the definition of Global Earthing System given by CENELEC Document HD 637 SI and from the results of the studies done on the last years on the interconnected earthing systems inside MV networks, the paper proposes some directions of deepening on the topic of Global Safety. Some of the themes whom the paper deals with are: the correct definition of proximity, interconnection and quasi-equipotentiality of the earth electrodes belonging to a Global Earthing System; the influence of the presence of HV/MV stations on h…

Video-Based Heartbeat Rate Measuring Method Using Ballistocardiography

2017

International audience; Video-based heartbeat rate measurement is a rapidly growing application in remote health monitoring. Video-based heartbeat rate measuring methods operate mainly by estimating photoplethysmography or ballistocardiography signals. These methods operate by estimating the microscopic color change in the face or by estimating the microscopic rigid motion of the head/facial skin. However, the robustness to motion artifacts caused by illumination variance and motion variance of the subject poses main challenge. We present a video-based heartbeat rate measuring framework to overcome these problems by using the principle of ballistocardiography. In this paper, we proposed a b…

HybridPLAY: A New Technology to Foster Outdoors Physical Activity, Verbal Communication and Teamwork

2015

This paper presents HybridPLAY, a novel technology composed of a sensor and mobile-based video games that transforms urban playgrounds into game scenarios. With this technology we aim to stimulate physical activity and playful learning by creating an entertaining environment in which users can actively participate and collaborate. HybridPLAY is different from other existing technologies that enhance playgrounds, as it is not integrated in them but can be attached to the different elements of the playgrounds, making its use more ubiquitous (i.e., not restricted to the playgrounds). HybridPLAY was born in 2007 as an artistic concept, and evolved after different phases of research and testing …
