Context awareness in ambient assisted living programmes for the elderly is a cornerstone in the current scenario of noncustomized service robots distributed around the world. This research proposes a context‐awareness system for a human–robot scene interpretation based on seven primary contexts and the American Occupational Therapy Association. The context‐awareness system defined here proposes an inference mechanism for the activity recognition supported on hierarchical Bayesian networks. However, when the information from sensors increases, the computational cost associated also increases. Thus, an evaluation of different Bayesian network models is necessary for decreasing its impact over the robot performance. Two topological models have been modelled and tested using OpenMarkov application: a two‐level approach of an input–observations layer and the activity recognition layer, and a three‐layer model setting apart a primary contexts layer, the input–observations layer, and the activity recognition layer. The qualitative and quantitative results presented here show better performance in terms of memory and memory in a three‐layer model. Besides, its effect on a hybrid architecture of a robotic platform is presented.

Resumen-Diferentes metodologías educativas han demostrado que un aspecto muy positivo para mejorar el aprendizaje del estudiante es que éste sea parte central del mismo, y especialmente que se involucre de manera activa en los procesos de aprendizaje. En este sentido la aplicación de técnicas de evaluación por pares ha sido una aproximación muy popular. Sin embargo, en enseñanzas de carácter ingenieril y especialmente enseñanzas técnicas, las actividades a evaluar implican en muchas ocasiones el uso de lenguajes o herramientas muy específicas. Esto hace que la evaluación por pares sea más compleja e implique que tanto alumnos como profesores tengan que utilizar diferentes contextos para la evaluación (como una herramienta de desarrollo software y una plataforma de aprendizaje). De cara a solventar este problema el presente trabajo propone el uso de sistemas de control de versiones que van a permitir almacenar los resultados obtenidos e interactuar al responsable del trabajo con sus revisores. En concreto, en este artículo se presenta la aplicación de técnicas de evaluación por pares en un grupo de 46 alumnos. Los resultados muestran que los discentes que usan activamente la herramienta con fines de evaluación tienen mejores resultados asociados.
Palabras clave: Evaluación por pares, Sistemas de Control de Versiones, Enseñanzas Técnicas, Interacción, ColaboraciónAbstract-Different studies have shown that a very positive factor to improve students learning is that they were the center of teaching and learning processes and also to be an active part in them. In this sense, the application of peer review techniques is a very popular approach. However, in engineering education and special in technical degrees the activities to assess consist of the use of very specific tools and languages. This makes peer evaluation more complex in this context than in others. It requires that both teachers and students use different tools and platforms to complete the evaluation. In order to solve this, the present work aims to apply a version control system to facilitate manage different results versions and also to interact with reviewers in the peer review process. In this specific work, the authors present a case study with 46 students that employ a version control system to apply peer review. Results show that students that use properly the tool have better performance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
