Algorithm for the comparison of human periodic movements using wearable devices

In the context of teaching-learning of motor skills in a virtual environment, videos are generally used. The person who wants to learn a certain movement watches a video and tries to perform the activity. In this sense, feedback is rarely thought of. This article proposes an algorithm in which two periodic movements are compared, the one carried out by an expert and the one carried out by the person who is learning, in order to determine how closely these two movements are performed and to provide feedback from them. The algorithm starts from the capture of data through a wearable device that yields data from an accelerometer; in this case, the data of the expert and the data of the person who is learning are captured in a dataset of salsa dance steps. Adjustments are made to the data in terms of Pearson iterations, synchronization, filtering, and normalization, and DTW, linear regression, and error analysis are used to make the corresponding comparison of the two datasets. With the above, it is possible to determine if the cycles of the two signals coincide and how closely the learner’s movements resemble those of the expert

Propuesta arquitectónica para integración de MOOC y wearable

Conference Derivative Article. Every day, people need to be trained, either to complement their professional skills or because of personal interests that lead to their well-being. Online education, especially MOOC and SPOC are good alternatives for carrying out continuing educational processes, but are not enough when it comes to learning motor skills. This paper shows a research approach on how MOOC can expand its functionalities so that it can be applied to learning motor skills. It also proposes the development of a project to integrate three components: the integration component, the wearable component and the open edX component for the future development of a "salsa" course. Finally, it proposes an architecture based on the 4+1 view model, where the functionality in different areas of the design is shown.Artículo Derivado de Conferencia.  Cada día, las personas necesitan ser capacitadas, ya sea para complementar sus habilidades profesionales o debido a intereses personales que conducen a su bienestar. La educación en línea, especialmente el MOOC y el SPOC, son buenas alternativas para llevar a cabo procesos educativos continuos, pero no son suficientes, cuando se trata de aprender habilidades motoras. Este artículo muestra un enfoque de investigación sobre cómo MOOC puede ampliar sus funcionalidades para que pueda aplicarse al aprendizaje de las habilidades motoras. También propone el desarrollo de un proyecto para integrar tres componentes: el componente de integración, el componente vestible y el componente abierto de edX para el desarrollo futuro de un curso de "salsa". Finalmente, propone una arquitectura basada en el modelo de vista 4+1, donde se muestra la funcionalidad en diferentes áreas del diseño
