This trend has its origin in the use of mobile devices as computational core and displays for Virtual Reality. Android is one of the most used platform in this context and Unity3d is a suitable graphic engine for such platform. In order to improve the immersive experience, some electronic devices, Arduino especially, are used to gather information, such as the movement of the user's arms or legs.

Many studies summarize the effect of the pandemic on the availability of mental health services and how this has changed during the pandemic. Concerned that potential increases in mental health conditions, had already prompted 90% of countries surveyed to include mental health and psychosocial support in their post COVID-19 response plans, but major gaps and concerns remain. In this paper we developed a de-stress proposal through a digital zen garden by using an augmented reality sandbox. The system provides patients with flexible interaction and easy control of the scenario, while making real time data recording. An objective evaluation method is proposed to review the effectiveness of the therapy. According to the evaluation results of patients’ training, the system is a low cost entertainment tool that augments patients’ motivation, and helps to increase the effectiveness of therapy.

La aplicación se centra en la educación por medio de la utilización de la tecnología de la realidad virtual, enriqueciendo la percepción del alumno a través de la interacción con objetos en un mundo artificial, facilitando su aprendizaje. Para ello se diseñó un sitio web en el cual se encuentra la aplicación para ser ejecutada directamente en el explorador web con la ayuda de un plugin o descargada y ejecutada como una aplicación nativa. El usuario navega en el entorno virtual que contiene una réplica en tres dimensiones de uno de los laboratorios de la Facultad Politécnica - U.N.E. En una de las salas se encuentran dos simulaciones de Física. Las pruebas realizadas consistieron en la ejecución del modelo de laboratorios y de las simulaciones. Los resultados obtenidos a partir de formularios muestran que la utilización de la realidad virtual es válida, aceptada y ayuda a la comprensión del contexto de las simulaciones.

Nowadays, both technologies are experiencing a deep interest from various spheres, including healthcare sector. The new infectious disease COVID-19 has had a catastrophic effect on the world’s demographics. Many patients with mild or severe COVID- 19 do not recover completely and present with a wide variety of chronic symptoms after infection, often of a neurological, cognitive or psychiatric nature. The most common signs of cognitive disorder can be summarized as mental fog, memory problems and concentration problems. The aim of this study was to analyze the opportunities for Virtual and Augmented Reality in the cognitive interventions related to mentioned disorders by searching for articles in scientific databases. We conclude that as these technologies and devices become cheaper and accessible worldwide, can at least be regarded as a rehabilitation therapy as effective as traditional training, and to some extent better than it.

En este último caso, expertos consideran que la ejercitación para rehabilitación mediante videojuegos en realidad virtual (VR-Games) realizada en la propia casa de los pacientes, constituye el futuro de estas terapias. Así, la realidad virtual en entornos telecontrolados se convierte en una herramienta valiosa debido a su capacidad de representar situaciones de la vida real en un contexto de total seguridad; además de facilitar el acceso a un tratamiento continuo y controlado a aquellos pacientes que poseen complicaciones de traslado, tanto de distancia como de tiempo. Este proyecto tiene como objetivo desarrollar un videojuego de realidad virtual multijugador en línea (Multiplayer Online Virtual Reality Game, o MOVR-Game) con dos aplicaciones interconectadas: una para los pacientes que se ejecutará en los lentes de realidad virtual; y otra para el profesional de la salud, quien desde su consultorio podrá realizar la gestión, seguimiento y adaptación de las sesiones de juego de cada uno de sus pacientes. La tecnología desarrollada tendrá como destinatarios a los pacientes de la Fundación Abril, organización de la salud que brinda rehabilitación a personas con discapacidad entre otras actividades.

Many studies summarize the effect of the pandemic on the availability of mental health services and how this has changed during the pandemic. Concerned that potential increases in mental health conditions, had already prompted 90% of countries surveyed to include mental health and psychosocial support in their post COVID-19 response plans, but major gaps and concerns remain. In this paper we developed a de-stress proposal through a digital zen garden by using an augmented reality sandbox. The system provides patients with flexible interaction and easy control of the scenario, while making real time data recording. An objective evaluation method is proposed to review the effectiveness of the therapy. According to the evaluation results of patients’ training, the system is a low cost entertainment tool that augments patients’ motivation, and helps to increase the effectiveness of therapy.

La aplicación se centra en la educación por medio de la utilización de la tecnología de la realidad virtual, enriqueciendo la percepción del alumno a través de la interacción con objetos en un mundo artificial, facilitando su aprendizaje. Para ello se diseñó un sitio web en el cual se encuentra la aplicación para ser ejecutada directamente en el explorador web con la ayuda de un plugin o descargada y ejecutada como una aplicación nativa. El usuario navega en el entorno virtual que contiene una réplica en tres dimensiones de uno de los laboratorios de la Facultad Politécnica - U.N.E. En una de las salas se encuentran dos simulaciones de Física. Las pruebas realizadas consistieron en la ejecución del modelo de laboratorios y de las simulaciones. Los resultados obtenidos a partir de formularios muestran que la utilización de la realidad virtual es válida, aceptada y ayuda a la comprensión del contexto de las simulaciones.

For further information contact us at helpdesk@openaire.euapps Other research product2021 Argentina EnglishAlvarado, Yoselie; Rodríguez, Graciela; Jofré, Nicolás; Fernández, Jacqueline; Guerrero, Roberto A.;Some time ago Virtual Reality and Augmented Reality were exclusively devoted to the gaming industry. Nowadays, both technologies are experiencing a deep interest from various spheres, including healthcare sector. The new infectious disease COVID-19 has had a catastrophic effect on the world’s demographics. Many patients with mild or severe COVID- 19 do not recover completely and present with a wide variety of chronic symptoms after infection, often of a neurological, cognitive or psychiatric nature. The most common signs of cognitive disorder can be summarized as mental fog, memory problems and concentration problems. The aim of this study was to analyze the opportunities for Virtual and Augmented Reality in the cognitive interventions related to mentioned disorders by searching for articles in scientific databases. We conclude that as these technologies and devices become cheaper and accessible worldwide, can at least be regarded as a rehabilitation therapy as effective as traditional training, and to some extent better than it.

En este último caso, expertos consideran que la ejercitación para rehabilitación mediante videojuegos en realidad virtual (VR-Games) realizada en la propia casa de los pacientes, constituye el futuro de estas terapias. Así, la realidad virtual en entornos telecontrolados se convierte en una herramienta valiosa debido a su capacidad de representar situaciones de la vida real en un contexto de total seguridad; además de facilitar el acceso a un tratamiento continuo y controlado a aquellos pacientes que poseen complicaciones de traslado, tanto de distancia como de tiempo. Este proyecto tiene como objetivo desarrollar un videojuego de realidad virtual multijugador en línea (Multiplayer Online Virtual Reality Game, o MOVR-Game) con dos aplicaciones interconectadas: una para los pacientes que se ejecutará en los lentes de realidad virtual; y otra para el profesional de la salud, quien desde su consultorio podrá realizar la gestión, seguimiento y adaptación de las sesiones de juego de cada uno de sus pacientes. La tecnología desarrollada tendrá como destinatarios a los pacientes de la Fundación Abril, organización de la salud que brinda rehabilitación a personas con discapacidad entre otras actividades.
