Localization and activity detection Based on the fusion of environment And inertial sensors = Localizaci��n y detecci��n de actividad Basadas en integraci��n de sensores y dispositivos inerciales

Los sensores inerciales (aceler��metros y gir��scopos) se han ido introduciendo poco a poco en dispositivos que usamos en nuestra vida diaria gracias a su minituarizaci��n. Hoy en d��a todos los smartphones contienen como m��nimo un aceler��metro y un magnet��metro, siendo complementados en losm��s modernos por gir��scopos y bar��metros. Esto, unido a la proliferaci��n de los smartphones ha hecho viable el dise��o de sistemas basados en las medidas de sensores que el usuario lleva colocados en alguna parte del cuerpo (que en un futuro estar��n contenidos en tejidos inteligentes) o los integrados en su m��vil. El papel de estos sensores se ha convertido en fundamental para el desarrollo de aplicaciones contextuales y de inteligencia ambiental. Algunos ejemplos son el control de los ejercicios de rehabilitaci��n o la oferta de informaci��n referente al sitio tur��stico que se est�� visitando. El trabajo de esta tesis contribuye a explorar las posibilidades que ofrecen los sensores inerciales para el apoyo a la detecci��n de actividad y la mejora de la precisi��n de servicios de localizaci��n para peatones. En lo referente al reconocimiento de la actividad que desarrolla un usuario, se ha explorado el uso de los sensores integrados en los dispositivos m��viles de ��ltima generaci��n (luz y proximidad, aceler��metro, gir��scopo y magnet��metro). Las actividades objetivo son conocidas como ���at��micas��� (andar a distintas velocidades, estar de pie, correr, estar sentado), esto es, actividades que constituyen unidades de actividades m��s complejas como pueden ser lavar los platos o ir al trabajo. De este modo, se usan algoritmos de clasificaci��n sencillos que puedan ser integrados en un m��vil como el Na��ve Bayes, Tablas y ��rboles de Decisi��n. Adem��s, se pretende igualmente detectar la posici��n en la que el usuario lleva el m��vil, no s��lo con el objetivo de utilizar esa informaci��n para elegir un clasificador entrenado s��lo con datos recogidos en la posici��n correspondiente (estrategia que mejora los resultados de estimaci��n de la actividad), sino tambi��n para la generaci��n de un evento que puede producir la ejecuci��n de una acci��n. Finalmente, el trabajo incluye un an��lisis de las prestaciones de la clasificaci��n variando el tipo de par��metros y el n��mero de sensores usados y teniendo en cuenta no s��lo la precisi��n de la clasificaci��n sino tambi��n la carga computacional. Por otra parte, se ha propuesto un algoritmo basado en la cuenta de pasos utilizando informaiii ci��n proveniente de un aceler��metro colocado en el pie del usuario. El objetivo final es detectar la actividad que el usuario est�� haciendo junto con la estimaci��n aproximada de la distancia recorrida. El algoritmo de cuenta pasos se basa en la detecci��n de m��ximos y m��nimos usando ventanas temporales y umbrales sin requerir informaci��n espec��fica del usuario. El ��mbito de seguimiento de peatones en interiores es interesante por la falta de un est��ndar de localizaci��n en este tipo de entornos. Se ha dise��ado un filtro extendido de Kalman centralizado y ligeramente acoplado para fusionar la informaci��n medida por un aceler��metro colocado en el pie del usuario con medidas de posici��n. Se han aplicado tambi��n diferentes t��cnicas de correcci��n de errores como las de velocidad cero que se basan en la detecci��n de los instantes en los que el pie est�� apoyado en el suelo. Los resultados han sido obtenidos en entornos interiores usando las posiciones estimadas por un sistema de triangulaci��n basado en la medida de la potencia recibida (RSS) y GPS en exteriores. Finalmente, se han implementado algunas aplicaciones que prueban la utilidad del trabajo desarrollado. En primer lugar se ha considerado una aplicaci��n de monitorizaci��n de actividad que proporciona al usuario informaci��n sobre el nivel de actividad que realiza durante un per��odo de tiempo. El objetivo final es favorecer el cambio de comportamientos sedentarios, consiguiendo h��bitos saludables. Se han desarrollado dos versiones de esta aplicaci��n. En el primer caso se ha integrado el algoritmo de cuenta pasos en una plataforma OSGi m��vil adquiriendo los datos de un aceler��metro Bluetooth colocado en el pie. En el segundo caso se ha creado la misma aplicaci��n utilizando las implementaciones de los clasificadores en un dispositivo Android. Por otro lado, se ha planteado el dise��o de una aplicaci��n para la creaci��n autom��tica de un diario de viaje a partir de la detecci��n de eventos importantes. Esta aplicaci��n toma como entrada la informaci��n procedente de la estimaci��n de actividad y de localizaci��n adem��s de informaci��n almacenada en bases de datos abiertas (fotos, informaci��n sobre sitios) e informaci��n sobre sensores reales y virtuales (agenda, c��mara, etc.) del m��vil. Abstract Inertial sensors (accelerometers and gyroscopes) have been gradually embedded in the devices that people use in their daily lives thanks to their miniaturization. Nowadays all smartphones have at least one embedded magnetometer and accelerometer, containing the most upto- date ones gyroscopes and barometers. This issue, together with the fact that the penetration of smartphones is growing steadily, has made possible the design of systems that rely on the information gathered by wearable sensors (in the future contained in smart textiles) or inertial sensors embedded in a smartphone. The role of these sensors has become key to the development of context-aware and ambient intelligent applications. Some examples are the performance of rehabilitation exercises, the provision of information related to the place that the user is visiting or the interaction with objects by gesture recognition. The work of this thesis contributes to explore to which extent this kind of sensors can be useful to support activity recognition and pedestrian tracking, which have been proven to be essential for these applications. Regarding the recognition of the activity that a user performs, the use of sensors embedded in a smartphone (proximity and light sensors, gyroscopes, magnetometers and accelerometers) has been explored. The activities that are detected belong to the group of the ones known as ���atomic��� activities (e.g. walking at different paces, running, standing), that is, activities or movements that are part of more complex activities such as doing the dishes or commuting. Simple, wellknown classifiers that can run embedded in a smartphone have been tested, such as Na��ve Bayes, Decision Tables and Trees. In addition to this, another aim is to estimate the on-body position in which the user is carrying the mobile phone. The objective is not only to choose a classifier that has been trained with the corresponding data in order to enhance the classification but also to start actions. Finally, the performance of the different classifiers is analysed, taking into consideration different features and number of sensors. The computational and memory load of the classifiers is also measured. On the other hand, an algorithm based on step counting has been proposed. The acceleration information is provided by an accelerometer placed on the foot. The aim is to detect the activity that the user is performing together with the estimation of the distance covered. The step counting strategy is based on detecting minima and its corresponding maxima. Although the counting strategy is not innovative (it includes time windows and amplitude thresholds to prevent under or overestimation) no user-specific information is required. The field of pedestrian tracking is crucial due to the lack of a localization standard for this kind of environments. A loosely-coupled centralized Extended Kalman Filter has been proposed to perform the fusion of inertial and position measurements. Zero velocity updates have been applied whenever the foot is detected to be placed on the ground. The results have been obtained in indoor environments using a triangulation algorithm based on RSS measurements and GPS outdoors. Finally, some applications have been designed to test the usefulness of the work. The first one is called the ���Activity Monitor��� whose aim is to prevent sedentary behaviours and to modify habits to achieve desired objectives of activity level. Two different versions of the application have been implemented. The first one uses the activity estimation based on the step counting algorithm, which has been integrated in an OSGi mobile framework acquiring the data from a Bluetooth accelerometer placed on the foot of the individual. The second one uses activity classifiers embedded in an Android smartphone. On the other hand, the design of a ���Travel Logbook��� has been planned. The input of this application is the information provided by the activity and localization modules, external databases (e.g. pictures, points of interest, weather) and mobile embedded and virtual sensors (agenda, camera, etc.). The aim is to detect important events in the journey and gather the information necessary to store it as a journal page.

Sistema de gu��a para personas invidentes a trav��s de bluetooth

El planteamiento inicial era proveer al individuo invidente de un sistema aut��nomo capaz de guiarle seg��n sus preferencias. El resultado obtenido al finalizar este proyecto ha sido un dispositivo aut��nomo configurable por el usuario mediante una aplicaci��n sw , desarrollada en la plataforma m��vil Android capaz de comunicarse con el dispositivo aut��nomo(m��vil personal). La idea de utilizar como plataforma de desarrollo sw Android, se bas�� fundamentalmente en que es c��digo open source, es gratuito y est�� presente en el 70 por ciento de los m��viles de Europa. La idea inicial era que ambos hubieran sido integrados en un mismo dispositivo, pero una vez comenzado el proyecto y habiendo evaluado los h��bitos actuales, decidimos adaptar la idea general del proyecto, a nuestros d��as. Para ello hicimos uso del dispositivo m��vil m��s usado hoy en d��a, como es nuestros tel��fonos m��viles, o m��s bien los llamado Smartphone, con los cuales podemos desde su aplicaci��n originaria que es llamar, hasta realizar multitud de operaciones al mismo tiempo como puede ser comunicaci��n por internet, posicionamiento via GPS, intercambio de ficheros por bluetooth��� tantas como podamos programar. Sobre este ��ltimo atributo, intercambio de informaci��n a trav��s de bluetooth, es la interfaz que vamos a aprovechar para la realizaci��n de nuestro proyecto. Hoy en d��a el 90% de los Smartphone tiene entre sus caracter��sticas de conectividad la posibilidad de intercambiar informaci��n v��a bluetooth. Una vez se tiene resuelto el interfaz entre el medio y el usuario se debe solucionar la forma de transformar la informaci��n para que los dispositivos m��viles recojan la informaci��n y sepan discernir entre la informaci��n importante y la que no lo es. Para ello hemos desarrollado una tarjeta configurable, con un m��dulo bluetooth comercial para enviar la informaci��n. El resultado final de esta tarjeta proporciona una manera f��cil de configurar diferentes mensajes que ser��n utilizados seg��n la situaci��n. ABSTRACT The initial approach consisted of a system that shows the way for blind people to get somewhere or something or provide to them important information, an autonomous system able to guide to their preference. After several analyses the project accomplish is a standalone device configurable by the user via an application sw, developed in Android mobile platform capable of communicating with the standalone device (personal cell phone). The decision of using the sw development platform of Android was due to the open source code concept and the great extent of presence on 70 percent of European mobiles. The first idea was that the sw and the device were integrated into a single device, but once the project had been started and having assessed the current habits, it has changed to be adapted to the present technology to get a better usability on the present-day. To achieve the project goals the most used mobile device today was used, our mobile phones, or rather called Smartphone, which you could use to phone your mother or perform many operations simultaneously such as communication online, positioning via GPS, bluetooth file trading program, etc. On this last attribute, information sharing via bluetooth, is the interface that it has been taken to complete the project. Today 90% of the Smartphone include in its connectivity features the ability to exchange information via bluetooth. Once that it was solved the interface between the environment and the final user, the next step incorporates the transformation of the information that the mobile devices collect from the environment to discern between the information the user configure to be notified or not. The hardware device that makes it possible is a configurable card with a bluetooth module that is able to send the information. The final result of this card provides an easy way to configure different messages, that we could use depending of the situation.

En este proyecto se realiza un estudio sobre herramientas que facilitan la creaci��n y distribuci��n de aplicaciones en distintas plataformas m��viles, con el fin de poder seleccionar la herramienta m��s apropiada en funci��n del proyecto a desarrollar. Previo al estudio de las herramientas para el desarrollo en plataformas m��ltiples se realiza un estudio de las herramientas y metodolog��as que facilitan los propietarios de los entornos IOS y Android. Este estudio previo permitir�� al lector conocer en m��s detalle las particularidades de cada uno de estos dos entornos, as�� como las pautas y buenas pr��cticas a seguir en el desarrollo de aplicaciones para dispositivos m��viles. Una vez finalizado el estudio, el lector sabr�� escoger una herramienta de desarrollo adaptada a cada proyecto en funci��n de su objeto, los recursos disponibles y las habilidades de los miembros del equipo de desarrollo. Adicionalmente al estudio, y como ejemplo de aplicaci��n, en el proyecto se realiza un caso pr��ctico de selecci��n de herramienta y aplicaci��n de la herramienta seleccionada a un proyecto de desarrollo concreto. El caso pr��ctico consiste en la creaci��n de un entorno que permite generar aplicaciones para la visualizaci��n de apuntes. Las aplicaciones permitir��n ver contenidos de tipo multimedia como ficheros de texto, sonidos, im��genes, v��deos y enlaces a contenidos externos. Adem��s estas aplicaciones se generar��n sin que el autor de las mismas tenga que modificar alguna de las l��neas del c��digo. Para ello, se han definido una serie de ficheros de configuraci��n en los que el autor de la aplicaci��n deber�� indicar los contenidos a mostrar y su ubicaci��n. Se han seleccionado recursos de tipo ���c��digo abierto��� para el desarrollo del caso pr��ctico, con el fin de evitar los costes asociados a las posibles licencias. El equipo de desarrollo del caso pr��ctico estar�� formado ��nicamente por el autor de este proyecto de fin de grado, lo que hace del caso de estudio un desarrollo sencillo, de manera que su futuro mantenimiento y escalabilidad no deber��an verse afectados por la necesidad de contar con equipos de desarrolladores con conocimientos espec��ficos o complejos. ABSTRACT. This document contains a study of tools that ease the creation and the distribution of the applications through different mobile platforms. The objective o this document is to allow the selection of the most appropriate tool, depending on the development objectives. Previous to this study about the tools for developing on multiple platforms, a study of IOS and Android tools and their methodologies is included on this document. This previous analysis will allow the reader to know in more detail the peculiarities of each of these environments, together with theirs requirements and the best practices of the applications development for mobile devices. By the end of this document the reader would be able to choose the adequate development tool for a project depending of its objective, its available resources and the developers team���s capabilities. Beside this study and as example of case study this final project includes a practical case of tool selection and its application to a specific development. The case study consists in the creation of an environment that allows generating applications to visualise notes. These applications will allow seeing contents of multimedia type such as: text files, sounds, images, videos, and links to external content. Furthermore these applications will be generated without their author having to modify any line of code, because a group of configuration files will be defined for such purpose. The author of the application only has to update this configuration with the content to show by the application and its location. The selected resources for the case study were of the type ���open source��� in order to avoid the cost associated to the potential licenses. The developers��� team for this case study has only one member, the author of this final project document and practical case developer. As a result the case study is a very simple development in a way that the future potential maintenance and scalability should not depend on the necessity of a highly qualified developers��� teams with a very specific knowledge on mobile platforms development.

El proyecto realizado, trata de una aplicaci��n desarrollada en la plataforma Android, orientada a personas con alg��n tipo de discapacidad sensorial o ps��quica. Dicha aplicaci��n fomenta el uso y la integraci��n de dispositivos m��viles en este tipo de sector de poblaci��n. Est�� pensada, para que, un usuario con discapacidad, pueda interactuar con ella y de forma transparente a ��l, se ha creado un sistema mediante el cual, se registra todo el comportamiento que ese usuario ha tenido durante el tiempo de uso de la aplicaci��n, con el fin de llevar un seguimiento del mismo; evaluar si existen cambios en ��l; determinar si son necesarios algunos cambios en la aplicaci��n que favorezcan una mejor��a en cuanto al uso y consecuci��n de resultados en el paciente, etc. Se ha combinado el uso de una aplicaci��n instalada sobre un sistema operativo de libre distribuci��n, concretamente Android, con un juguete de c��digo abierto, como es Sphero. Eso ha permito el desarrollo de una aplicaci��n perfectamente ajustada a los requisitos funcionales definidos, con una robustez y eficiencia similar a una aplicaci��n de sistemas operativos m��viles cerrados. Es importarte remarcar, que la primera finalidad de este proyecto es ofrecer la posibilidad de usar un juguete, como Sphero, que est�� orientado a un sector de poblaci��n sin discapacidad, haciendo uso de cualquier dispositivo m��vil, a personas con diferentes grados de discapacidad sensorial, motora y ps��quica. Siempre clarificando, que no existe la posibilidad de usar esta aplicaci��n para cualquier tipo y grado de discapacidad, ya que, ello supondr��a, un proyecto de una envergadura enorme. El hecho de usar un dispositivo m��vil, es un derecho, que todos tenemos. Y por ello, se espera que tras la lectura y comprensi��n de este proyecto, se motive a los lectores a seguir desarrollando aplicaciones para que cualquier usuario, con discapacidad o no, tenga las mismas oportunidades de interactuaci��n con dispositivos m��viles. The carried out project, is an application developed on the Android platform , aimed at people with some kind of sensory or mental disability . This application encourages the use and integration of mobile devices in this type of population sector. It is designed to be interacted by a disable person and transparently to that user, it has been created a system by which all behavior, that user has had during the time of use of the application, is recorded, that���s to keep track of it ; assess whether there are changes in it, determine if changes are needed in the application that favor an improvement in the use and achieving patient outcomes , etc. . It has combined the use of an application installed on an open source operating system, namely Android, an open source toy , as is Sphero . That has made it possible to develop an application perfectly adjusted to the functional requirements defined with a robustness and efficiency similar to a mobile OS application closed. It is important to note, that the first aim of this project is to offer the possibility of using a toy, like Sphero , which is geared to a sector of the population without disabilities , using any mobile device , for people with different degrees of sensory impairment , motor and mental . Always clarifying that there is no possibility to use this application for any type and degree of disability, because the magnitude of the project would have been infinitely greater. The fact of using a mobile device, is a right we all have. And so, it is expected that upon reading and understanding of this project, motivate readers to continue developing applications for any user , disabled or not, have the same opportunities for interaction with mobile devices .

Correlaci��n de medidas de diversos sistemas de sensores inal��mbricos a trav��s del uso de smartphone

Este Proyecto Fin de Grado se centra en la definici��n de unos interfaces y el desarrollo de unos m��dulos que los ofrezcan y que permitan desarrollar un sistema para Smartphone mediante el que se puedan obtener medidas tanto de dispositivos biom��tricos como de una red inal��mbrica de sensores (WSN ��� Wireless Sensor Network). Estos dos tipos de medidas deben poder ser mostradas de manera que se observe gr��ficamente su correlaci��n espacio-temporal. Por tanto, estos interfaces ofrecen, principalmente, la posibilidad de gestionar un n��mero indeterminado de dispositivos biom��tricos y tomar medidas de ellos, adem��s de mecanismos de almacenamiento para dichas medidas. Tambi��n existe la posibilidad de crear una representaci��n gr��fica de dichas medidas. Por ��ltimo, se desarrolla un interfaz para obtener informaci��n proveniente de una red de sensores inal��mbricos instalada en un determinado entorno en el cual el usuario estar�� realizando sus propias medidas. Adem��s, se lleva a cabo la creaci��n de la aplicaci��n comentada, que hace uso de las interfaces especificadas, para realizar la correlaci��n de las medidas. La aplicaci��n permite al usuario mantener una lista de dispositivos, pudiendo consultar los par��metros de configuraci��n de los mismos y tomar las medidas de aquellos que desee. Podr�� visualizar en todo momento las medidas que se van realizando, y, por ��ltimo, podr�� representarlas gr��ficamente en pantalla. Los interfaces est��n creados de forma que sean flexibles de modo que puedan a��adirse nuevas funciones en un futuro y permitan ser utilizados para diferentes aplicaciones. Los m��dulos que ofrecen estos interfaces est��n desarrollados para cumplir todas las funcionalidades que esperamos llevar a cabo en la aplicaci��n creada. ABSTRACT. This Final Degree Project is focused on the definition of a set of interfaces, together with the implementation of the modules that comply with them, with the aim of creating a smartphone-based system to obtain measurements from both biometric devices and a wireless sensor network (WSN). These two types of measurements have to be graphically shown in order to observe their spatial and temporal correlation. Thus, the main purpose of the aforementioned interfaces is to manage an indeterminate number of biometric devices in order to obtain and store the measurements provided by them. There is also the possibility of creating a graphical representation of the data. In addition to all this, an interface has been developed for obtaining the information coming from a wireless sensor network deployed in the area where the user is taking his/her measurements. Also as part of the work performed, the smartphone application that utilizes the specified interfaces has been implemented, in order to actually perform the measurements correlation. This application allows the user to maintain the biometric devices list and control their configuration, including the activation of the measurements taking process. These data can be visualized anytime and, moreover, they can be represented graphically in the smartphone screen. The design of the interfaces is flexible in the sense that new functionality may be easily added to them in the future and new applications with different purposes may make use of them. The modules implemented as part of this Final Degree Project have been developed in order to comply with all the requirements of the smartphone system described above.

El ��ltimo cap��tulo quiere englobar el uso de todas las lecciones aprendidas en las lecciones anteriores para crear una aplicaci��n que bien podr��a ser una aplicaci��n real para un cliente. Se trata de una aplicaci��n que muestra en tiempo real informaci��n sobre las c��maras de tr��fico de la ciudad de Madrid. ABSTRACT. The improvements that have occurred in recent years in terms of power and capabilities of mobile phones that we use on a daily basis, bring an increment in demand for all kind of applications, from general consumer applications, games or even internal applications that offer solutions to companies. There are different operating systems for mobile phones as will be explained later in the introductory chapter. In that chapter the answer for why this Thesis focuses on the study of the Android operating system is given as well. First an overview of the state of the art about the world of mobile applications will be referred. The pros and cons of each operating system will be explained, detailing the programming language used in each of them and their main characteristics. Then in chapter three will be discussed in more depth the Android operating system, from its history and beginnings to the main components for the creation of an application, to the internal architecture of the system or virtual machine. The goal of chapter three is to give the readers a context that allows them to understand the following chapters, where the core of this Thesis is. The fourth chapter contains a series of incremental practices covering a large part of the potential of the Android operating system for application development. Those practices grow in difficulty and are supported by the previous in order to have at the end a single solution that fits all lessons. The last chapter wants to embrace the use of all the lessons learned in previous lessons to create an application that could well be an actual application for a client. It is an application that displays real-time information off traffic cameras of the city of Madrid.

WSM : metodolog��a de web scraping para Android y ejemplificaci��n mediante la aplicaci��n UPMDroid

En la realizaci��n de este proyecto se ha tratado principalmente la tem��tica del web scraping sobre documentos HTML en Android. Como resultado del mismo, se ha propuesto una metodolog��a para poder realizar web scraping en aplicaciones implementadas para este sistema operativo y se desarrollar�� una aplicaci��n basada en esta metodolog��a que resulte ��til a los alumnos de la escuela. Web scraping se puede definir como una t��cnica basada en una serie de algoritmos de b��squeda de contenido con el fin de obtener una determinada informaci��n de p��ginas web, descartando aquella que no sea relevante. Como parte central, se ha dedicado bastante tiempo al estudio de los navegadores y servidores Web, y del lenguaje HTML presente en casi todas las p��ginas web en la actualidad as�� como de los mecanismos utilizados para la comunicaci��n entre cliente y servidor ya que son los pilares en los que se basa esta t��cnica. Se ha realizado un estudio de las t��cnicas y herramientas necesarias, aport��ndose todos los conceptos te��ricos necesarios, as�� como la proposici��n de una posible metodolog��a para su implementaci��n.

ABSTRACT. The main topic of this project is about the web scraping over HTML documents on Android OS. As a result thereof, it is proposed a methodology to perform web scraping in deployed applications for this operating system and based on this methodology that is useful to the ETSIST school students. Web scraping can be defined as a technique based on a number of content search algorithms in order to obtain certain information from web pages, discarding those that are not relevant. As a main part, has spent considerable time studying browsers and Web servers, and the HTML language that is present today in almost all websites as well as the mechanisms used for communication between client and server because they are the pillars which this technique is based. We performed a study of the techniques and tools needed, providing all the necessary theoretical concepts, as well as the proposal of a possible methodology for implementation. Finally it has codified UPMdroid application, developed in order to illustrate the implementation of the previously proposed methodology and also to give the student a mobile ETSIST Android support to facilitate access and display those most important data of the current academic year such as: class schedules and scores for the subjects in which you are enrolled. This application, in addition to implement the proposed methodology is also a very interesting tool for the student, as it allows a simple and intuitive way of use these school functionalities thus fixing the viewing web content on devices.

Interacci��n desde dispositivos Android v��a Bluetooth, con juguete teledirigido, para su uso por personas con discapacidad

El Proyecto Fin de Carrera, con t��tulo, "Interacci��n desde dispositivos Android v��a Bluetooth, con juguete teledirigido, para su uso por personas con discapacidad" pretende completar la primera versi��n de la aplicaci��n sobre dispositivo Android para manejar un juguete teledirigido a��adiendo nuevas formas de interactuar con el dispositivo Android. Para este caso, el juguete teledirigido es el mismo: el robot esf��rico llamado Sphero. Dicho robot posee una interfaz a trav��s de la cual puede recibir instrucciones, y mediante las cuales, se puede poner en movimiento o iluminarse con diferentes colores. Esta ampliaci��n facilitar�� la interacci��n del usuario con el dispositivo Android, adem��s de ampliar la funcionalidad hacia la inversa: recibir los movimientos del robot Sphero en el dispositivo Android cuando es manejado con la mano. Completando la primera versi��n, como cumplimiento de este Proyecto Fin de Carrera, se han realizado una serie de mandos nuevos, los cuales abarcan desde el manejo del robot por instrucciones de voz, movimientos del dispositivo Android desde el que se ejecuta, describir una trayectoria dibujada previamente en el dispositivo Android, o, realizar una serie de movimientos corregidos mediante la aplicaci��n gracias a los l��mites de movimientos para un usuario concreto que pueden introducirse. Adem��s, completando lo anteriormente escrito, se ha desarrollado una aplicaci��n web que registrar�� todos los datos de uso del juguete, la cual, explota una base de datos que almacena toda interacci��n con el juguete. Estos datos estar��n asociados a un usuario, debido a que la aplicaci��n Android debe perfilarse para el uso de un usuario concreto. El perfilado de usuario se ha completado a��adiendo una serie de informaci��n que puede ser ��til para la persona que analice el comportamiento de una persona con discapacidad que utilice la aplicaci��n. Por ��ltimo, se ha realizado un estudio de elementos externos que puedan facilitar la interacci��n con los dispositivos Android a personas que sufran alguna discapacidad. ABSTRACT. The Thesis, titled "Interaction from Android devices via Bluetooth, with remote control toy, for use by people with disabilities" project aims to complete the first version of the application on Android device to manage a remote control toy adding new ways of interacting to Android device. For this case, the remote control toy is the same: the spherical robot called Sphero. This robot has an interface through which it can receive instructions, and by means of which can be set in motion or illuminated with different colors. This expansion will facilitate user interaction with the Android device, and extend the functionality to reverse: receiving Sphero robot movements in the Android device when handled by hand. Completing the first version, in fulfillment of this Thesis, there have been a number of new controls, which range from control of robot by voice instructions, movements Android device from which it runs, describe a path drawn previously on your Android device, or perform a series of movements corrected by applying through limits of movement for a particular user can be made. Besides completing the above written, has developed a web application that will record all data on use of the toy, which exploits a database that stores all interaction with the toy. These data will be associated with a user, because the Android application should be outlined for the use of a particular user. The user profile is completed by adding a range of information that can be useful for the person to analyze the behavior of a disabled person to use the application. Finally, a study was made of external elements that can facilitate interaction with Android devices to people who suffer from a disability.

HDTourist: exploring urban data on Android

The Web of Data currently comprises ? 62 billion triples from more than 2,000 different datasets covering many fields of knowledge3. This volume of structured Linked Data can be seen as a particular case of Big Data, referred to as Big Semantic Data [4]. Obviously, powerful computational configurations are tradi- tionally required to deal with the scalability problems arising to Big Semantic Data. It is not surprising that this ?data revolution? has competed in parallel with the growth of mobile computing. Smartphones and tablets are massively used at the expense of traditional computers but, to date, mobile devices have more limited computation resources. Therefore, one question that we may ask ourselves would be: can (potentially large) semantic datasets be consumed natively on mobile devices? Currently, only a few mobile apps (e.g., [1, 9, 2, 8]) make use of semantic data that they store in the mobile devices, while many others access existing SPARQL endpoints or Linked Data directly. Two main reasons can be considered for this fact. On the one hand, in spite of some initial approaches [6, 3], there are no well-established triplestores for mobile devices. This is an important limitation because any po- tential app must assume both RDF storage and SPARQL resolution. On the other hand, the particular features of these devices (little storage space, less computational power or more limited bandwidths) limit the adoption of seman- tic data for different uses and purposes. This paper introduces our HDTourist mobile application prototype. It con- sumes urban data from DBpedia4 to help tourists visiting a foreign city. Although it is a simple app, its functionality allows illustrating how semantic data can be stored and queried with limited resources. Our prototype is implemented for An- droid, but its foundations, explained in Section 2, can be deployed in any other platform. The app is described in Section 3, and Section 4 concludes about our current achievements and devises the future work.

Testing of Android testing tools: development of a benchmark for the evaluation

With the ever growing trend of smart phones and tablets, Android is becoming more and more popular everyday. With more than one billion active users i to date, Android is the leading technology in smart phone arena. In addition to that, Android also runs on Android TV, Android smart watches and cars. Therefore, in recent years, Android applications have become one of the major development sectors in software industry. As of mid 2013, the number of published applications on Google Play had exceeded one million and the cumulative number of downloads was more than 50 billionii. A 2013 survey also revealed that 71% of the mobile application developers work on developing Android applicationsiii. Considering this size of Android applications, it is quite evident that people rely on these applications on a daily basis for the completion of simple tasks like keeping track of weather to rather complex tasks like managing one���s bank accounts. Hence, like every other kind of code, Android code also needs to be verified in order to work properly and achieve a certain confidence level. Because of the gigantic size of the number of applications, it becomes really hard to manually test Android applications specially when it has to be verified for various versions of the OS and also, various device configurations such as different screen sizes and different hardware availability. Hence, recently there has been a lot of work on developing different testing methods for Android applications in Computer Science fraternity. The model of Android attracts researchers because of its open source nature. It makes the whole research model more streamlined when the code for both, application and the platform are readily available to analyze. And hence, there has been a great deal of research in testing and static analysis of Android applications. A great deal of this research has been focused on the input test generation for Android applications. Hence, there are a several testing tools available now, which focus on automatic generation of test cases for Android applications. These tools differ with one another on the basis of their strategies and heuristics used for this generation of test cases. But there is still very little work done on the comparison of these testing tools and the strategies they use. Recently, some research work has been carried outiv in this regard that compared the performance of various available tools with respect to their respective code coverage, fault detection, ability to work on multiple platforms and their ease of use. It was done, by running these tools on a total of 60 real world Android applications. The results of this research showed that although effective, these strategies being used by the tools, also face limitations and hence, have room for improvement. The purpose of this thesis is to extend this research into a more specific and attribute-����� oriented way. Attributes refer to the tasks that can be completed using the Android platform. It can be anything ranging from a basic system call for receiving an SMS to more complex tasks like sending the user to another application from the current one. The idea is to develop a benchmark for Android testing tools, which is based on the performance related to these attributes. This will allow the comparison of these tools with respect to these attributes. For example, if there is an application that plays some audio file, will the testing tool be able to generate a test input that will warrant the execution of this audio file? Using multiple applications using different attributes, it can be visualized that which testing tool is more useful for which kinds of attributes. In this thesis, it was decided that 9 attributes covering the basic nature of tasks, will be targeted for the assessment of three testing tools. Later this can be done for much more attributes to compare even more testing tools. The aim of this work is to show that this approach is effective and can be used on a much larger scale. One of the flagship features of this work, which also differentiates it with the previous work, is that the applications used, are all specially made for this research. The reason for doing that is to analyze just that specific attribute in isolation, which the application is focused on, and not allow the tool to get bottlenecked by something trivial, which is not the main attribute under testing. This means 9 applications, each focused on one specific attribute. The main contributions of this thesis are: A summary of the three existing testing tools and their respective techniques for automatic test input generation of Android Applications. ��� A detailed study of the usage of these testing tools using the 9 applications specially designed and developed for this study. ��� The analysis of the obtained results of the study carried out. And a comparison of the performance of the selected tools.
