Commonalities between networking in multiplayer computer games and negotiation processes in a future multi-layered Air Traffic Management (ATM) system

First, this paper describes a future layered Air Traffic Management (ATM) system centred in the execution phase of flights. The layered ATM model is based on the work currently performed by SESAR [1] and takes into account the availability of accurate and updated flight information ?seen by all? across the European airspace. This shared information of each flight will be referred as Reference Business Trajectory (RBT). In the layered ATM system, exchanges of information will involve several actors (human or automatic), which will have varying time horizons, areas of responsibility and tasks. Second, the paper will identify the need to define the negotiation processes required to agree revisions to the RBT in the layered ATM system. Third, the final objective of the paper is to bring to the attention of researchers and engineers the communalities between multi-player games and Collaborative Decision Making processes (CDM) in a layered ATM system

Píldoras formativas y videojuegos aplicados al estudio de la Ingeniería Acústica

Las TIC cada vez tienen un mayor impacto social en el mundo de la enseñanza a distancia, están surgiendo nuevos conceptos relacionados con la forma de llevar el aprendizaje a las personas. La generación de contenidos supone una práctica costosa en tiempo, recursos y personas, es por eso la tendencia a que sean reutilizables, accesibles, portables y durables. Es aquí donde toman su importancia las píldoras formativas o de conocimiento, estando asociadas a un concepto y con una duración entre 5 y 15 minutos. Este trabajo pretende desarrollar píldoras formativas a modo de videos de corta duración sobre conceptos acústicos y guiones de prácticas de laboratorio tratados a lo largo del máster. Se desarrollará también a modo de videojuego el guión de una de las prácticas sirviendo como complemento a los videos. El trabajo se divide en dos partes bien diferenciadas, una de estudio teórico tanto de la tecnología para el desarrollo de los videos, que servirá de guía para futuras píldoras, como del contenido de éstos, y otra parte que tratará la implementación y adaptación de los videos y de los videojuegos. SUMMARY ICTs are becoming a greater social impact in the world of distance learning are emerging concepts related to learning how to take people. Content generation is a costly exercise in time, resources and people, is why the tendency to be reusable, accessible, portable and durable. This is where the importance of taking pills training or knowledge, being associated with a concept and with a duration between 5 and 15 minutes. This work aims to develop training pills as a short videos on concepts and scripts acoustic laboratory practices discussed during the Master. Also be developed as a script for a game of serving practices to supplement the videos. The work is divided into two distinct parts, a theoretical study of both the technology for the development of the videos, which will guide future pills, and the content of these, and another part that will address the implementation and adaptation of the videos and of video games.

Diseño y desarrollo de videojuegos 2D bajo plataforma comercial

Desde su aparición en los años 50, los videojuegos han estado muy presentes en la vida de los jóvenes. Un mercado que nunca se ha mantenido estático, donde la revolución científica vivida en el siglo XX ha colaborado en su gran evolución. Empezando por un juego implementado en una máquina de rayos catódicos, pasando por las recreativas, hasta meterse en los hogares de cualquier familia con los PC y videoconsolas. Contando además con una calidad gráfica que hace difícil diferenciar hoy en día entre realidad y mundo virtual. Pero no sólo los videojuegos están concebidos para el ocio y desconectar de la realidad. Existe un concepto llamado “gamification”, una técnica que busca el transmitir conocimientos, ayudar a personas con discapacidades, facilitar las rehabilitaciones, etc… transformando actividades que puedan parecer aburridas, en algo divertido. Aquí es donde entran los juegos serios, juegos que buscan tales objetivos. Dado que los videojuegos hoy en día están muy metidos en la sociedad, y cada vez llegan a más público de distintas edades y género. Hemos elegido este proyecto para fomentar la creación de videojuegos serios, a través de un tutorial completo con el motor gráfico Unity, intentando usar el mayor número de herramientas posible. ABSTRACT. From the beginning in the 1950s, video games have played an important role in young people’s life. A market that has never been static, where scientific revolution lived in the twentieth century has contributed to a great evolution. Starting from a game implemented on a cathode ray machine, reaching arcade rooms and then getting into families with PCs and consoles. Nowadays the graphic quality makes difficult to differentiate between reality and the virtual world. Not only video games are designed for leisure and to disconnect from the real world for a while. There is a concept called “gamification”, a technique which tends to transmit knowledge, give help to people with disabilities, facilitate rehab, etc. Transforming activities, which might seem boring into fun ones. This is where serious games take place, games looking for the goals mentioned. Since nowadays video games are completely set in our society, and increasing a wider public with different ages and gender, this project has been chosen to promote the creation of serious video games, through a complete tutorial with the game engine - Unity - attempting to use as many tools as it can be possible.

Multi-textured 3D humanoid reconstruction through passive and active automatic techniques = Reconstrucción de humanoides 3D multi-texturados mediante técnicas pasivas y activas automáticas

The proliferation of video games and other applications of computer graphics in everyday life demands a much easier way to create animatable virtual human characters. Traditionally, this has been the job of highly skilled artists and animators that painstakingly model, rig and animate their avatars, and usually have to tune them for each application and transmission/rendering platform. The emergence of virtual/mixed reality environments also calls for practical and costeffective ways to produce custom models of actual people. The purpose of the present dissertation is bringing 3D human scanning closer to the average user. For this, two different techniques are presented, one passive and one active. The first one is a fully automatic system for generating statically multi-textured avatars of real people captured with several standard cameras. Our system uses a state-of-the-art shape from silhouette technique to retrieve the shape of subject. However, to deal with the lack of detail that is common in the facial region for these kind of techniques, which do not handle concavities correctly, our system proposes an approach to improve the quality of this region. This face enhancement technique uses a generic facial model which is transformed according to the specific facial features of the subject. Moreover, this system features a novel technique for generating view-independent texture atlases computed from the original images. This static multi-texturing system yields a seamless texture atlas calculated by combining the color information from several photos. We suppress the color seams due to image misalignments and irregular lighting conditions that multi-texturing approaches typically suffer from, while minimizing the blurring effect introduced by color blending techniques. The second technique features a system to retrieve a fully animatable 3D model of a human using a commercial depth sensor. Differently to other approaches in the current state of the art, our system does not require the user to be completely still through the scanning process, and neither the depth sensor is moved around the subject to cover all its surface. Instead, the depth sensor remains static and the skeleton tracking information is used to compensate the user’s movements during the scanning stage. RESUMEN La popularización de videojuegos y otras aplicaciones de los gráficos por ordenador en el día a día requiere una manera más sencilla de crear modelos virtuales humanos animables. Tradicionalmente, estos modelos han sido creados por artistas profesionales que cuidadosamente los modelan y animan, y que tienen que adaptar específicamente para cada aplicación y plataforma de transmisión o visualización. La aparición de los entornos de realidad virtual/mixta aumenta incluso más la demanda de técnicas prácticas y baratas para producir modelos 3D representando personas reales. El objetivo de esta tesis es acercar el escaneo de humanos en 3D al usuario medio. Para ello, se presentan dos técnicas diferentes, una pasiva y una activa. La primera es un sistema automático para generar avatares multi-texturizados de personas reales mediante una serie de cámaras comunes. Nuestro sistema usa técnicas del estado del arte basadas en shape from silhouette para extraer la forma del sujeto a escanear. Sin embargo, este tipo de técnicas no gestiona las concavidades correctamente, por lo que nuestro sistema propone una manera de incrementar la calidad en una región del modelo que se ve especialmente afectada: la cara. Esta técnica de mejora facial usa un modelo 3D genérico de una cara y lo modifica según los rasgos faciales específicos del sujeto. Además, el sistema incluye una novedosa técnica para generar un atlas de textura a partir de las imágenes capturadas. Este sistema de multi-texturización consigue un atlas de textura sin transiciones abruptas de color gracias a su manera de mezclar la información de color de varias imágenes sobre cada triángulo. Todas las costuras y discontinuidades de color debidas a las condiciones de iluminación irregulares son eliminadas, minimizando el efecto de desenfoque de la interpolación que normalmente introducen este tipo de métodos. La segunda técnica presenta un sistema para conseguir un modelo humano 3D completamente animable utilizando un sensor de profundidad. A diferencia de otros métodos del estado de arte, nuestro sistema no requiere que el usuario esté completamente quieto durante el proceso de escaneado, ni mover el sensor alrededor del sujeto para cubrir toda su superficie. Por el contrario, el sensor se mantiene estático y el esqueleto virtual de la persona, que se va siguiendo durante el proceso, se utiliza para compensar sus movimientos durante el escaneado.

Negotiation Games: Acquiring Skills by Playing

This paper shows the research done at the School of Industrial Engineers (ETSII) of the Technical University of Madrid (UPM), in two consecutive academic courses. In this negotiation game each team is formed by three students playing different roles, with a different degree of complexity. The game is played three different times changing the conditions and doing the Zones of Possible Agreement (ZOPA) smaller so the negotiation is going “harder” and it was more difficult for the team to achieve an agreement. Roles were distributed according to the student’s experience, since it was understood that difficulty of the roles was different, especially when there was set a time limit for negotiation. The combination of playing and training has shown that students without particularly good negotiating skills at the beginning of the experiment attained better final results than those who have natural negotiating skills, but no benefit of training.

Online games for the teaching of mathematics

In this article we present a didactic experience developed by the GIE (Group of Educational Innovation) “Pensamiento Matemático” of the Polytechnics University of Madrid (UPM), in order to bring secondary students and university students closer to Mathematics. It deals with the development of a virtual board game called Mate-trivial. The mechanics of the game is to win points by going around the board which consists of four types of squares identified by colours: “Statistics and Probability”, “Calculus and Analysis”, “Algebra and Geometry” and “Arithmetic and Number Theory ”. When landing on a square, a question of its category is set out: a correct answer wins 200 points, if wrong it loses 100 points, and not answering causes no effect on the points, but all the same, two minutes out of the 20 minutes that each game lasts are lost. For the game to be over it is necessary, before those 20 minutes run out, to reach the central square and succeed in the final task: four chained questions, one of each type, which must be all answered correctly. It is possible to choose between two levels to play: Level 1, for pre-university students and Level 2 for university students. A prototype of the game is available at the website “Aula de Pensamiento Matemático” developed by the GIE: http://innovacioneducativa.upm.es/pensamientomatematico/. This activity lies within a set of didactic actions which the GIE is developing in the framework of the project “Collaborative Strategies between University and Secondary School Education for the teaching and learning of Mathematics: An Application to solve problems while playing”, a transversal project financed by the UPM.

Traditional education vs modern education. What is the impact of teaching techniques' evolution on students learning process?

The main objective of this article is to focus on the analysis of teaching techniques, ranging from the use of the blackboard and chalk in old traditional classes, using slides and overhead projectors in the eighties and use of presentation software in the nineties, to the video, electronic board and network resources nowadays. Furthermore, all the aforementioned, is viewed under the different mentalities in which the teacher conditions the student using the new teaching technique, improving soft skills but maybe leading either to encouragement or disinterest, and including the lack of educational knowledge consolidation at scientific, technology and specific levels. In the same way, we study the process of adaptation required for teachers, the differences in the processes of information transfer and education towards the student, and even the existence of teachers who are not any longer appealed by their work due which has become much simpler due to new technologies and the greater ease in the development of classes due to the criteria described on the new Grade Programs adopted by the European Higher Education Area. Moreover, it is also intended to understand the evolution of students’ profiles, from the eighties to present time, in order to understand certain attitudes, behaviours, accomplishments and acknowledgements acquired over the semesters within the degree Programs. As an Educational Innovation Group, another key question also arises. What will be the learning techniques in the future?. How these evolving matters will affect both positively and negatively on the mentality, attitude, behaviour, learning, achievement of goals and satisfaction levels of all elements involved in universities’ education? Clearly, this evolution from chalk to the electronic board, the three-dimensional view of our works and their sequence, greatly facilitates the understanding and adaptation later on to the business world, but does not answer to the unknowns regarding the knowledge and the full development of achievement’s indicators in basic skills of a degree. This is the underlying question which steers the roots of the presented research.

Integration of SCORM packages into web games

This paper presents a model that enables the integration of SCORM packages into web games. It is based on the fact that SCORM packages are prepared to be integrated into Learning Management Systems and to communicate with them. Hence in a similar way they can also be integrated into web games. The application of this model results in the linkage between the Learning Objects inside the package and specific actions or conditions in the game. The educational content will be shown to the players when they perform these actions or the conditions are met. For example, when they need a special weapon they will have to consume the Learning Object to get it. Based on this model we have developed an open source web platform which main aim is to facilitate teachers the creation of educational games. They can select existing SCORM packages or upload their own ones and then select a game template in which the Learning Objects will be integrated. The resulting educational game will be available online. Details about the model and the developed platform are explained in this paper. Also links to the platform and an example of a generated game will be provided.

Enseñanza (y aprendizaje) virtual de Geología por parte del alumno=Virtual education (and learning) of Geology by students

Una de las maneras más efectivas para asentar conocimientos se produce cuando, además de realizar un aprendizaje práctico, se intentan transmitir a otra persona. De hecho, los alumnos muchas veces prestan más atención a sus compañeros que al profesor. En la E.T.S.I. Minas de Madrid se ha llevado a cabo un programa de innovación educativa en asignaturas relacionadas con la Geología mediante nuevas tecnologías para mejorar el aprendizaje basado en el trabajo práctico personal del alumno, con la realización de vídeos en el medio físico (campo) en los que explican los aspectos geológicos visibles a diferentes escalas. Estos vídeos se han subido a las plataformas “moodle”, “facebook” y canal “youtube” donde compañeros, alumnos de otras Universidades y personas interesadas pueden consultarlos. De esta manera se pretende que, además de adquirir conocimientos geológicos, los alumnos adquieren el hábito de expresarse en público con un lenguaje técnico. Los alumnos manifestaron su satisfacción por esta actividad, aunque idea del rodaje de vídeos no resultó inicialmente muy popular. Se ha observado una mejora en las calificaciones, así como un incremento de la motivación. De hecho, los estudiantes manifestaron haber adquirido, además de los conceptos geológicos, seguridad a la hora de expresarse en público. Palabras clave: innovación educativa, nuevas tecnologías (TIC), Geología Abstract- Knowledge is gained by practice, but one of the most effective ways is when one tries to transmit it to others. Likewise, students pay more attention to their classmates than to teachers. In the Geological Engineering Department of the Madrid School of Mines, we have run an educational innovation program in courses related to Geology using new technologies (ITC) in order to increase the acquisition of geological knowledge. This program is designed mainly on the basis of individual and group work with video recordings in the field in which students explain geological concepts at various scales. These videos have been uploaded to the “Moodle”, “Facebook” and “YouTube” channel of the Madrid School of Mines, where other students from the same university or elsewhere can view them. Students acquire geological knowledge and the ability to address the general public using technical language. The realization of these videos has been warmly welcomed by students. Notably, they show increased motivation, accompanied by an improvement in grades, although at the beginning this program was not very popular because of student insecurity. Students have expressed that they learnt geological concepts but also gained confidence in public speaking using technical language

Development and implementation of a virtual laboratory for training process improvement in the mechanics of continuous media

The project arises from the need to develop improved teaching methodologies in field of the mechanics of continuous media. The objective is to offer the student a learning process to acquire the necessary theoretical knowledge, cognitive skills and the responsibility and autonomy to professional development in this area. Traditionally the teaching of the concepts of these subjects was performed through lectures and laboratory practice. During these lessons the students attitude was usually passive, and therefore their effectiveness was poor. The proposed methodology has already been successfully employed in universities like University Bochum, Germany, University the South Australia and aims to improve the effectiveness of knowledge acquisition through use by the student of a virtual laboratory. This laboratory allows to adapt the curricula and learning techniques to the European Higher Education and improve current learning processes in the University School of Public Works Engineers -EUITOP- of the Technical University of Madrid -UPM-, due there are not laboratories in this specialization. The virtual space is created using a software platform built on OpenSim, manages 3D virtual worlds, and, language LSL -Linden Scripting Language-, which imprints specific powers to objects. The student or user can access this virtual world through their avatar -your character in the virtual world- and can perform practices within the space created for the purpose, at any time, just with computer with internet access and viewfinder. The virtual laboratory has three partitions. The virtual meeting rooms, where the avatar can interact with peers, solve problems and exchange existing documentation in the virtual library. The interactive game room, where the avatar is has to resolve a number of issues in time. And the video room where students can watch instructional videos and receive group lessons. Each audiovisual interactive element is accompanied by explanations framing it within the area of knowledge and enables students to begin to acquire a vocabulary and practice of the profession for which they are being formed. Plane elasticity concepts are introduced from the tension and compression testing of test pieces of steel and concrete. The behavior of reticulated and articulated structures is reinforced by some interactive games and concepts of tension, compression, local and global buckling will by tests to break articulated structures. Pure bending concepts, simple and composite torsion will be studied by observing a flexible specimen. Earthquake resistant design of buildings will be checked by a laboratory test video.

Ludomática, herramienta de aprendizaje

Desde los comienzos de la enseñanza, siempre se han buscado formas innovadoras para transmitir el conocimiento de profesor a alumno. Desde recursos materiales hasta sistemas de enseñanza complejos, todos juegan un papel esencial en el aprendizaje del alumno. Durante el siglo XVII comienzan a desarrollarse nuevas corrientes de enseñanza cuyo objetivo era el aprendizaje ameno del individuo. Hoy en día pueden utilizarse multitud de medios para desarrollar estos métodos pedagógicos, entre ellos, los juegos interactivos. Con el boom de la tecnología y el desarrollo de las tecnologías de la información, los tutores encuentran en los dispositivos electrónicos todo un apoyo para realizar esta tarea, lo cual viene acompañado de una revolución inminente en la enseñanza. El objetivo de este proyecto es la creación de un videojuego educativo que permita tanto aprender más fácilmente a los alumnos como evaluar los conocimientos adquiridos por éstos a los profesores. Se ha creado Ludomática, un videojuego de tipo juego de mesa donde los jugadores tendrán que utilizar sus conocimientos en determinados temas para ganar la partida. El videojuego puede ser configurado con distintas preguntas del tema que se desee y en tres niveles de dificultad. Además, cuenta con la posibilidad de configurar el número de jugadores, de preguntas y de puntuación máxima, con objeto de crear partidas más o menos largas. Ludomática se constituye como una herramienta educativa completa y personalizable, además de atractiva, mediante la cual los profesores pueden innovar su forma de enseñanza y los alumnos pueden aprender divirtiéndose---ABSTRACT---Since the beginning of teaching, professors have always looked for innovative ways to transmit knowledge from teacher to student. From material resources to teaching complex systems, they all play a vital role in student learning. The development of new forms of education aimed to create enjoyable ways to teach started during the XVII century. Nowadays, It’s easy to find multiple elements to develop this pedagogical methods, including interactive games. Because of the “tech boom” and the rise of the Information and Communication Technologies, teachers can have a lot of support in electronic devices to carry out this task, which comes with an inminent revolution of teaching. The objective of this project is to create an educational video game that allows not only learn much more easily for students, but also evaluate the knowledge acquired by these for teachers. Ludomática has been created as a board videogame where players have to use their knowledge in specific topics to win the game. The game can be configured with different questions of the topic desired and three difficulty levels. It also has the ability to set the number of players, questions and maximum score, in order to control the duration of the game. Ludomática constitutes a complete and customizable educational tool, also attractive, whereby teachers can innovate their teaching forms and students can learn while having fun.
