Current challenges of interactive digital television

Este artículo presenta una descripción general de alto nivel de los desafíos actuales que implica la televisión digital interactiva debido a los cambios en el comportamiento del usuario bajo la experiencia actual de ver televisión. Presentamos una breve revisión de los múltiples trabajos encontrados en la literatura que abordan problemas específicos que surgen al convertir un entorno de observación única en una experiencia interactiva. Además, hemos previsto una arquitectura de sistema que evidencia cómo los dispositivos que acompañan la segunda pantalla, como los teléfonos móviles o las tabletas, pueden utilizarse para facilitar el proceso de interactividad desde los puntos de vista técnico y operativo. En particular, esta arquitectura admite aplicaciones interactivas innovadoras para el reconocimiento automático de anuncios utilizando un dispositivo de segunda pantalla como una interfaz de usuario amigable. © 2017 IEEE.This article presents a high level overview of the current challenges that Interactive Digital Television involves due to the changes in user's behaviour under the current TV watching experience. We present a short review of multiple works found in the literature which have addressed specific issues that arise on converting an only-watching setting onto an interactive experience. Moreover, we have envisioned a system architecture that evidence how second screen accompanying devices, such as mobile phones or tablets, can be used to facilitate the interactivity process from the technical and operative viewpoints. In particular, this architecture supports innovative interactive applications for automatic ad recognition utilizing a second screen device as a friendly user interface.Salina

ShimiTV, a t-learning system for android TV

The development and gradual adoption of Interactive Digital Television (iDTV) has enabled novel mechanisms to provide services and content to television viewers. This article presents ShimiTV as an application to provide educational resources and exercises to learn languages. It includes the definition of an agile development methodology and architecture that can be used to build a t-learning application. The implementation is done on the emerging operating system Android TV. © 2018 IEEE.The development and gradual adoption of Interactive Digital Television (iDTV) has enabled novel mechanisms to provide services and content to television viewers.

Arquitectura para una red de sensores web basada en SWE (sensor web enablement): caso de estudio para la implementación en sensores hidrometeorológicos

The growth of information and communication technologies associated with the needs to access immediately information generated by different sensors made the implementation and the use of communication protocols to acquire and interchange data necessary. In this sense, Sensor Web Enablement (SWE) developed by OGC (Open Geospatial Consortium) and each of its components constitute the most appropriate tool to achieve this goal. This research project proposes an architecture based in SWE that allows to access in real-time sensors belonging to a hydro-meteorological network. The architecture has been verified and validated through the implementation of a case study, using the hydrometeorological station “Marianza” located in the Azuay province; station run by PROMAS (Programa para el Manejo del Agua y el Suelo).The growth of information and communication technologies associated with the needs to access immediately information generated by different sensors made the implementation and the use of communication protocols to acquire and interchange data necessary.

Flipping the classroom with MOOCs. A pilot study exploring differences between self-regulated learners

El uso del modelo Flipped Classroom (FC) apoyado con tecnología ha permitido optimizar el tiempo de clase, cubriendo las demandas de aprendizaje de los alumnos y adaptándose a su ritmo de trabajo. Sin embargo, los alumnos se desempeñan a un ritmo diferente y utilizan recursos externos durante su aprendizaje, lo que les exige la capacidad de autorregularse. En este artículo, se presenta un estudio piloto e investiga cómo los estudiantes con diferentes perfiles de autorregulación navegan a través de un MOOC cuando se utiliza como parte de la metodología FC. Para cumplir con los objetivos del estudio, mediante el uso de técnicas de Process Mining, se investigó en archivos de registro que registran el comportamiento del curso de N = 149 alumnos en un MOOC Open edX utilizado para admitir FC. Los resultados muestran que los alumnos que estuvieron expuestos a la FC obtuvieron mejores calificaciones que sus contrapartes. También, los alumnos con diferentes perfiles de SRL siguen diferentes caminos de navegación. Este estudio abre la posibilidad a otros investigadores de explorar cómo se desempeñan los estudiantes en un MOOC usando FC.La Plat
