Simulación de Plataformas Robóticas de Movimiento para Aplicaciones de Realidad Virtual Mediante Filtros Digitales
2017
[ES] El uso de plataformas robóticas de movimiento en simuladores de vehículos y aplicaciones de Realidad Virtual es relativamente habitual. Sin embargo, el ajuste de los algoritmos que controlan su funcionamiento, denominados algoritmos de washout, no es sencillo y requiere de numerosas pruebas hasta obtener una apropiada fidelidad de movimiento. Disponer de herramientas que permitan simular plataformas de movimiento puede permitir simplificar esta tarea. Es por ello que este trabajo presenta un método para la caracterización y simulación de manipuladores robóticos mediante filtros digitales de segundo orden, sencillo de implementar y ajustar a partir de una caracterización previa. El simu…
MIME: A mixed-space collaborative system with three immersion levels and multiple users
2018
Shared spaces for remote collaboration are nowadays possible by considering a variety of users, devices, immersion systems, interaction capabilities, navigation paradigms, etc. There is a substantial amount of research done in this line, proposing different solutions. However, still a more general solution that considers the heterogeneity of the involved actors/items is lacking. In this paper, we present MIME, a mixed-space tri-collaborative system. Differently from other mixed-space systems, MIME considers three different types of users (in different locations) according to the level of immersion in the system, who can interact simultaneously – what we call a tri-collaboration. For the thr…
Arte digitalizado y arte digital: las manifestaciones artísticas en la era digital
2003
Analizamos las potencialidades que el medio digital ofrece al campo de la creación, constatando la aparición de nuevas obras más interactivas, abiertas y dinámicas y de un nuevo tipo de espectador más activo. Destacamos las repercusiones que este medio está ejerciendo en el mundo de los museos y las galerías que están apostando, en algunos casos, por incorporar estas obras a sus espacios expositivos y al mercado del arte. Reseñamos la importancia de Internet y el surgimiento del net-art, así como de la Realidad Virtual y el Arte evolutivo. (A)
Uso de la Realidad Virtual en Educación: un análisis bibliométrico
2022
Virtual Reality includes different technologies through which a user can experience a virtual world created in 3 dimensions by computer. Although its adoption has been slow, since the devices required to access virtual reality were expensive, there have been experiences in education since the 1990s. The present study carries out a bibliometric study in which 1074 articles related to the use of virtual reality in education from 1990 to the beginning of 2021 have been analyzed. It has been studied, from a quantitative point of view, the evolution of the annual scientific production, collaboration and production of authors, nationalities and sources of the articles. An analysis of citations, c…
Treatment of flying phobia using virtual reality exposure with or without cognitive restructuring: Participant's preferences
2015
This study analyses participants’ preferences regarding two exposure treatment modali- ties for Fear of Flying (FF): virtual reality exposure treatment (VRET) by itself or VRET plus cognitive restructuring (VRET+CR). An alternating treatment conditions design was established and a non-concurrent multiple baseline design across individuals (four participants) was used. Both conditions were equally effective and after the treatment all the participants took a flight. At the end of each session the participants were asked for their opinion on the condition they received. High mean scores were obtained in both conditions; non-significant differences between the two condi- tions were found. When…
Normalizing the eating pattern with virtual reality for bulimia nervosa: a case report
2015
AbstractThe aim of the present study was to analyze the effects of a virtual reality (VR) component as a therapeutic tool to normalize eating patterns, as part of the cognitive-behavioral treatment of a bulimia nervosa (BN) patient. Results indicated that the patient made significant progress with her eating habits; binges and vomits were eliminated completely. Moreover, when the VR started the patient avoided food, especially meat (5 over 5), and it was reduction of this avoidance in the lasts sessions (2 and 3 over 5). It was also observed a reduction in the avoidance and the fear of eating (from 10 and 9 to 6 and 5 respectively) and increased the impulse control (from 2 to 7). The patien…
The treatment of the body image disturbances in eating disorders and clinically significant change
2014
Body image disturbance is a significant maintenance and prog-nosis factor in eating disorders. Hence, existing eating disorder treatments can benefit from direct intervention in patients’ body image. This paper in-cludes a controlled study comparing cognitive behavioural treatment for eating disorders with and without a component for body image treatment using virtual reality techniques. The objective of this work was to check if both types of treatment produced a change clinically significant at the end of the treatment and the follow-up to the year, in body image, eating disor-ders and general psychopathology. Thirty-four participants diagnosed with eating disorders were treated and compa…
La realidad virtual en las intervenciones psicológicas con pacientes oncológicos
2014
El objetivo de este trabajo es presentar las principales aportaciones de la Realidad Virtual (RV) en el tratamiento psicologico con pacientes oncologicos, y describir un programa de intervencion que utiliza esta tecnologia para promover bienestar emocional en pacientes hospitalizados. La RV se presenta como una prometedora herramienta de apoyo al paciente oncologico. Diversos estudios plantean su utilidad para hacer algunos tratamientos medicos mas tolerables, para reducir los niveles de distres y dolor, asi como promover mayores niveles de emociones positivas. Se ha empleado principalmente con pacientes ambulatorios, existiendo una menor proporcion de propuestas dirigidas al periodo de hos…

TRIDIMENSIONAL ANALYSIS PROPOSAL TO INTEGRATE DIFFERENT ARCHAEOLOGICAL FIELDWORK CONDUCTED AT CUEVA DE LA COCINA (DOS AGUAS, VALENCIA)
2016
[EN] At this document we present a computer protocol, designed for the development of a digital environment which will allow virtual reconstruction of both, the stratigraphic information and the material record found at Cueva de la Cocina (Dos Aguas, Valencia). By this we also mean to relate the most recent fieldwork at the site to that carried on during the 1970s. The first interventions inside the cavity date back to the first half of the XX century, when a complex sequence, which comprehended layers mainly related to the last hunter-gutherers and the first farmers, was identified. Accurateness, both describing and gathering precise information of the site was not a priority according to …
