Sistema multiplataforma de gestión integral de huertos urbanos

En este Proyecto Fin de Grado se construirá una herramienta de gestión integral de centros hortícolas donde una serie de huertos cuidados por personas en situación de discapacidad son alquilados a terceros. Esta iniciativa se lleva a cabo gracias a la iniciativa “La Huerta de Montecarmelo” de la Fundación Carmen Pardo-Valcarce de Madrid. Este proyecto es el resultado de la colaboración entre la Escuela Técnica Superior de Ingeniería de Sistemas Informáticos y la Fundación, a través de un programa de Prácticas Externas que duró doce meses. Por una parte, tras años de trabajo en esta Obra Social, se encontró que muchos de los clientes, pasado el verano, se desvinculaban de las tareas y del medio. A fin de solucionar esos problemas, se propuso construir una aplicación web, comunicada con otros dispositivos, como Smartphones, permitiendo un flujo de trabajo más ágil y notificando a los arrendatarios de cada cambio en sus huertos, por ejemplo: fotos recientes, notificaciones de recolecta o futuros cursos. El proyecto se llevó a cabo con éxito a lo largo de 2012 y 2013. Abstract In this Final Degree Project we build a complete horticulture center management tool where a set of gardens, which are kept by people with disabilities, are leased to third parties. This project is carried out within the La Huerta Montecarmelo initiative of the Carmen Pardo-Valcarce Foundation in Madrid. The project was the result of collaboration between the School of Computer Systems Engineering of the Technical University of Madrid and that Foundation through an External Practices program that lasted twelve months. By one hand, over the years of Social Work in this initiative, it was found that some clients after spring were easily disconnected from the tasks involved to the garden. By the other, all the management of more than two hundred of gardens becomes a very complex task due to lots of paperwork. To solve these problems and more, we proposed to build a web application, relying on other devices, such as Smartphones, allowing a more agile workflow and notifying customers of any change related to its garden, for example: recent photographs, notifications of harvest or future courses. The project was successfully carried out throughout 2012 and 2013.

Authentication in mobile devices through hand gesture recognition

This article proposes an innovative biometric technique based on the idea of authenticating a person on a mobile device by gesture recognition. To accomplish this aim, a user is prompted to be recognized by a gesture he/she performs moving his/her hand while holding a mobile device with an accelerometer embedded. As users are not able to repeat a gesture exactly in the air, an algorithm based on sequence alignment is developed to correct slight differences between repetitions of the same gesture. The robustness of this biometric technique has been studied within 2 different tests analyzing a database of 100 users with real falsifications. Equal Error Rates of 2.01 and 4.82% have been obtained in a zero-effort and an active impostor attack, respectively. A permanence evaluation is also presented from the analysis of the repetition of the gestures of 25 users in 10 sessions over a month. Furthermore, two different gesture databases have been developed: one made up of 100 genuine identifying 3-D hand gestures and 3 impostors trying to falsify each of them and another with 25 volunteers repeating their identifying 3- D hand gesture in 10 sessions over a month. These databases are the most extensive in published studies, to the best of our knowledge.
