TL;DR: In this paper, the effects on the balance, attention, visuomotor coordination, discomfort and anxiety after the use of a videogame with virtual reality have been analyzed and recommended for people using too much time virtual reality.
Abstract: Side-effects of a videogame with Inmersive Virtual Reality. The progresses of virtual reality development are so fast that it is necessary to study also his possible side-effects. This study tries to analyze the effects on the balance, attention, visuomotor coordination, discomfort and anxiety after the use of a videogame with virtual reality. Four groups have been used with measurements pre-post, a control-group and three experimental groups with different intensity using virtual reality. The sample of 120 participants was randomized, pre-assigned by sex and studies, 30 for each condition. A Smart Visor VFX full stereoscopic immersive type with detector of position was used. The videogame was Unreal Tournament. As results, 13% of the participants had to retire due to uncomfortable side-effects. The side-effects were major in the group of high intensity use, less in those of daily use where there was an adjustment of these side-effects, and even less in the group with only an hour. It is concluded with some recommendations for people using too much time virtual reality.

TL;DR: In this article, the results of un proceso de revision bibliografica sobre rehabilitation of miembro superior basada en ambientes virtuales were presented.
Abstract: En este articulo se presentan los resultados de un proceso de revision bibliografica sobre rehabilitacion de miembro superior basada en ambientes virtuales. El estudio parte de los siguientes interrogantes sobre el estado actual del conocimiento en el area mencionada: ?como inciden los entornos virtuales frente a la rehabilitacion tradicional?, ?que metricas de desempeno se han aplicado en la rehabilitacion virtual de miembro superior? y ?que dispositivos hardware se utilizan en rehabilitacion virtual?. Para responder las anteriores preguntas se realizo una busqueda de articulos cientificos en el motor de busqueda Google Scholar y en las bases de datos PubMed, HINARI, ProQuest y Science Direct. De la revision realizada se concluyo que pese a la existencia de decenas de indices de desempeno para cuantificar la habilidad motriz, no existen criterios para seleccionar el indice que mejor se adapta a los objetivos de un determinado proceso de rehabilitacion

TL;DR: In this article, a sistema de real reality virtual inmersivo 3D with interaccion natural de usuario desarrollado con el proposito de facilitar la inspeccion de aerogeneradores con fine didacticos.
Abstract: Los sistemas de realidad virtual inmersivos tienen una creciente relevancia en el ambito educativo como herramientas didacticas que motivan el aprendizaje a traves de dos conceptos clave: la inmersion y la interaccion. En este documento describimos el uso de sistemas de realidad virtual en la educacion y tomamos como caso de estudio un sistema de realidad virtual inmersivo 3D con interaccion natural de usuario desarrollado con el proposito de facilitar la inspeccion de aerogeneradores con fines didacticos. El sistema sugerido busca la convergencia tecnologica de equipos de visualizacion, adquisicion de informacion y software de graficos. Para lograrlo, seguimos la metodologia de desarrollo de software basado en componentes de Pressman. Los resultados cualitativos de una primera evaluacion al sistema indican que la propuesta permite experimentar la realidad virtual inmersiva y ofrece una gran similitud al entorno real, con la posibilidad de interactuar por medio de gestos y movimientos corporales. Esto contribuye a motivar el aprendizaje y fomentar el interes de los usuarios en practicar con esta tecnologia. Ademas, la convergencia tecnologica entre los equipos de visualizacion, interaccion y software grafico permite dar un paso adelante en el desarrollo de este tipo de herramientas didacticas.

TL;DR: Nintendo® Wii-based therapy is a non-immersive virtual reality therapy used to recover upper extremity (UE) motor function in children with cerebral palsy and results indicate that NWT is effective at improving various UE impaired motor skills inChildren with CP.
Abstract: Background: Nintendo® Wii-based therapy (NWT) is a non-immersive virtual reality therapy used to recover upper extremity (UE) motor function in children with cerebral palsy (CP). We aimed primarily to elucidate the effectiveness of NWT in improving UE motor and functional impaired abilities in children with CP, compared to conventional therapy or no intervention. The secondary aim was to assess if NWT is more effective when used alone or combined with conventional therapy. Methods: A systematic review with meta-analysis was conducted from a bibliographic search in PubMed, Scopus, PEDro, Web of Science, and CINHAL, ending in October 2021, in accordance with PRISMA guidelines. We included randomized controlled trials that compared NWT vs. conventional therapy or no intervention in terms of their impact on different UE impaired abilities (grip strength, tip grip strength, UE dissociated movements, functional capacity in daily living activities, gross and fine motor dexterity, and grasping ability) in children with CP. Effect size was calculated with standardized mean difference (SMD) and its 95% confidence interval (95% CI). Results: Nine studies (276 participants) were included. NWT is more effective than conventional therapy at improving grip strength (SMD = 0.5, 95% CI 0.08, 0.91), tip grip strength (SMD = 0.95, 95% CI 0.3, 1.61), and grasping ability (SMD = 0.72, 95%CI 0.14, 1.3). NWT is more effective than conventional therapy at improving functional capacity in daily living activities (SMD = 0.83, 95% CI 0.07, 1.56). For fine manual dexterity, NWT was better than no intervention (SMD = 3.12, 95% CI 1.5, 4.7). Conclusions: Our results indicate that NWT is effective at improving various UE impaired motor skills in children with CP.

TL;DR: In this article, the authors investigate the use of immersive advertising in the context of virtual reality and its presence on YouTube, analyzing its advertising use focused on minors, and analyzes the convenience of consumption of these campaigns for this public, as well as in what conditions its application is recommended.
Abstract: espanolLa realidad virtual se erige como discurso mas alla de lo tecnologico con creciente visibilidad en todos los ambitos sociales, conformandose como uno de los protagonistas de la cibercultura. La publicidad no es ajena a este auge del relato inmersivo y empieza a ser habitual que campanas con enfoque transmedia empleen este recurso frente a otras narrativas y canales de difusion. De entre los publicos existentes, los menores de edad son especialmente sensibles a los mensajes a los que son expuestos y por ello han de estar tutelados. Existen multitud de estudios cuyo eje central es ocupado por este sector social, aunque son escasos aquellos que lo interrelacionan con la publicidad digital. En este articulo, se expone conceptualmente la realidad virtual y su presencia en YouTube, analizando su uso publicitario enfocado hacia los menores de edad. La presente investigacion trata de dilucidar si la publicidad inmersiva cumple con los estrictos parametros de control de la convencional en su trato con los menores, y analiza la conveniencia de consumo de estas campanas para este publico, asi como en que condiciones es recomendable su aplicacion. EnglishVirtual reality stands as a discourse beyond technology, with increasing visibility in all social areas, and becoming one of the protagonists of cyberculture. Advertising is no stranger to this boom of immersive storytelling, and it is becoming usual that campaigns with a transmedia approach use this resource in the face of other narratives and channels of dissemination. Among the existing publics, minors are especially sensitive to the messages to which they are exposed, and therefore must be protected. There is a multitude of studies whose central axis is occupied by this social sector, although there are few studies that interrelate it with digital advertising. In this paper, virtual reality and its presence on YouTube are conceptually exposed, analyzing its advertising use focused on minors. The present investigation tries to elucidate if the immersive advertising complies with the strict control parameters of conventional advertising in its dealings with the minors, and analyzes the convenience of consumption of these campaigns for this public, as well as in what conditions its application is recommended. portuguesA realidade virtual se coloca como um discurso alem do tecnologico, com crescente visibilidade em todas as areas sociais, tornando-se um dos protagonistas da cibercultura.

TL;DR: The Spanish version of the State-Trait Anxiety Inventory (STAI) was translated into Spanish with the assistance of psychologists from 10 different Latin Ameriaconic countries as mentioned in this paper.
Abstract: The goal of this study was to describe the construction of scales for measuring- state (A-State) and trait (A-Trait) anxiety that would be suitable for use in interamerican, cross-cultural research. The State-Trait Anxiety Inventory (Spielberger, et al., 1970) was translated into Spanish with the assistance of psychologists from 10 different Latin American countries. To evaluate the reliability and equivalence of the Spanish and English forms of the STAI, these scales were given in counterbalanced order to bilingual 5s in Texas and Puerto Rico. In both samples, high item- remainder correlations and alpha coefficients ranging from .82 to .95 established the internal consistency of the Spanish A-State and A-Trait scales. Evidence of the equivalence of these scales was provided by correlations between the Spanish and English forms that ranged from .83 to .94. High test-retest reliability was also found for the Spanish A-Trait scale but not for the A-State scale. As expected, the A-State scale was influenced by transitory situational stress, whereas the A-Trait scale was stable over time. It was concluded that the Spanish STAI provides internally consistent and reliable scales for measuring state and trait anxiety which are essentially equivalent to the English STAI A-State and A-Trait scales.

TL;DR: The challenges each of these factors present to the effective design of virtual environments and systematic approaches to the resolution of each of them are discussed.
Abstract: Virtual environments are envisioned as being systems that will enhance the communication between humans and computers. If virtual systems are to be effective and well received by their users, considerable human-factors research needs to be accomplished. This paper provides an overview of many of these human-factors issues, including human performance efficiency in virtual worlds (which is likely influenced by task characteristics, user characteristics, human sensory and motor physiology, multimodal interaction, and the potential need for new design metaphors); health and safety issues (of which cybersickness and deleterious physiological aftereffects may pose the most concern); and the social impact of the technology. The challenges each of these factors present to the effective design of virtual environments and systematic approaches to the resolution of each of these issues are discussed.

TL;DR: The aetiology of the effects is sufficiently different to that for simulators or transport systems to justify a new term, virtual reality-induced symptoms and effects (VRISE).
Abstract: An experimental program of research was carried out to assess the potential health and safety effects of participating in virtual environments (VEs) via head-mounted displays (HMDs) This paper presents the results obtained from nine experiments examining the effects experienced during and after participation in a variety of VR systems, VE designs, and task requirements, for a total participant sample of 148 individuals A combination of methods including self-report scales, performance measures, physiological indicators, observation, interview, and user attitude/opinion questionnaires were used to measure simulator (VE) sickness, postural instability, psychomotor control, perceptual judgment, concentration, stress, and ergonomics effects Greatest effects across the different systems, VEs, and exposure times were found for sickness symptoms and physiological measures, with some concern over postural instability and physical ergonomics, also Although many of the effects were relatively minor and short lived, they were serious for five percent of participants and irritating for a considerable percentage more The aetiology of the effects is sufficiently different to that for simulators or transport systems to justify us using a new term, virtual reality-induced symptoms and effects (VRISE) Implications are drawn for VR system design, VE specification, and the ways in which industrial use of VR/VE should be planned and supported

TL;DR: In this review, examples in the scientific literature of commercially available and tailor-made games used for education and training with patients and medical students and doctors are summarized.
Abstract: Although a great deal of media attention has been given to the negative effects of playing video games, relatively less attention has been paid to the positive effects of engaging in this activity. Video games in health care provide ample examples of innovative ways to use existing commercial games for health improvement or surgical training. Tailor-made games help patients be more adherent to treatment regimens and train doctors how to manage patients in different clinical situations. In this review, examples in the scientific literature of commercially available and tailor-made games used for education and training with patients and medical students and doctors are summarized. There is a history of using video games with patients from the early days of gaming in the 1980s, and this has evolved into a focus on making tailor-made games for different disease groups, which have been evaluated in scientific trials more recently. Commercial video games have been of interest regarding their impact on surgical skill. More recently, some basic computer games have been developed and evaluated that train doctors in clinical skills. The studies presented in this article represent a body of work outlining positive effects of playing video games in the area of health care.
