    Fue implementado un ambiente virtual de aprendizaje siguiendo algunos principios de la Educación a Distancia, para auxiliar las clases presenciales de Física. Para su construcción fueron investigadas las herramientas y técnicas más adecuadas. Los recursos que el ambiente presenta posibilitan la organización de las informaciones de forma eficiente, estimulan la interactividad y manipulación de los contenidos a través del desarrollo de actividades adecuadas (lecturas, testes online, simulaciones de fenómenos físicos de difícil visualización), así como permiten un aprendizaje auto-controlado. La evaluación del ambiente por alumnos durante el año 2002 indica que su utilización contribuye para establecer las condiciones necesarias para alcanzar un aprendizaje significativo en la sala de clases. Following the guidelines of distance education, a virtual learning environment was implemented to aid physics classrooms lessons. For its construction, the appropriated tools and techniques were explored. The resources within the environment allows an efficient organization of the information, helps to stimulate the interactivity and the manipulation of the contents through the development of adequate activities (readings, online tests, physical phenomena of difficult visualization simulations), as well as a self-controlled learning. The evaluation of the environment made by the students during the year 2002 indicates that it contributes to establish the necessary conditions to reach a significant learning in a classroom.

    The paper presents a work executed in the virtual prototyping area. It is described as a procedure for the implementation of a CNC (Computerized Numeric Command) lathe prototype using software for virtual environment development. This procedures focus mainly on the interlocking system (functionality) and geometric model (physical design) of the lathe. Consequently, this work aims at checking the potential and limitations of this graphic interface tool, considering the complexity of the data required for product prototyping in manufacturing or assembly.

    Virtual Reality has become, once again, a popular and interesting topic, both as a research and commercial field. This trend has its origin in the use of mobile devices as computational core and displays for Virtual Reality. Android is one of the most used platform in this context and Unity3d is a suitable graphic engine for such platform. In order to improve the immersive experience, some electronic devices, Arduino especially, are used to gather information, such as the movement of the user's arms or legs. Although these three elements are often used in Virtual Reality, few studies use all of them in combination. Those who do, do not develop a reusable framework for their implementations. In this work we present AnArU, a framework for physical human interaction in Virtual Reality. The goal of AnArU is to allow an easy, efficient and extensible communication between electronic devices and the Virtual Reality system.

    La manera en la que las personas interactúan con las computadoras no es siempre la misma. A medida que la tecnología avanza se desarrollan nuevas herramientas, nuevas propuestas de interacción emergen y se crean nuevas interfaces. Las interfaces de Realidad Aumentada constituyen un ejemplo de tal desarrollo. Las mismas ofrecen al usuario un entorno combinando, por un lado, información del mundo real, y por otro, información sintética creada y manejada por la computadora. Una correcta fusión de estos dos mundos en un único entorno e inferfaz de usuario es un elemento esencial en todo sistema de Realidad Aumentada. Las distintas áreas de aplicación de estos sistemas poseen cada una sus propios requerimientos. En este artículo presentamos las diferentes líneas de investigación relacionadas con Realidad Aumentada que están actualmente en desarrollo en nuestro laboratorio.

    La representación tridimensional de grandes volúmenes de datos de terreno requiere un gran número de polígonos y de texturas, significando un problema la transmisión por red de los modelos. El enfoque multiresolución permite la transmisión progresiva, es decir, la transmisión de un modelo básico de baja resolución seguido de refinamientos sucesivos hasta completar la resolución deseada. En este trabajo se presenta un nuevo modelo multiresolución denominado Bitree geométricotexturado que, a diferencia de trabajos previos en el área de modelos multiresolución, representa tanto la geometría como la textura de un tetTeno. Se plantea la aplicación del análisis multiresolución de la transformada Wavelet en el modelo Bitree. Además, se propone una arquitectura cliente-servidor Java y un algoritmo de transmisión progresiva de los modelos por Internet.

    Una de las tareas importantes involucradas en el proceso de minería es la selección adecuada del equipo o maquinaria a utilizar durante dicho proceso. Estos equipos difieren según el trabajo que realicen, y para ello deben ser seleccionados de manera tal que se logre obtener el mayor beneficio y eficiencia de cada uno de ellos. La importancia de esta tarea radica en que durante el proceso minero intervienen muchas variables técnicas, geométricas (características propias del yacimiento) y económicas. Además existen muchas marcas, modelos y tamaños de equipamientos que compiten y que muchas veces entregan resultados similares a los realmente esperados por el usuario. Actualmente el ingeniero que efectúa la selección no cuenta con una herramienta automática confiable y apropiada para evaluar estos equipos y decidir cuál de ellos es mejor para su proyecto. Generalmente esta tarea se realiza a “mano” en función a la experiencia. Dicha tarea de selección se facilitaría si en lugar de hacerla manualmente, se dispusiera de un programa que conociendo las características de los equipos disponibles en el mercado y las condiciones de trabajo permitan realizar en forma automática la mejor selección. La simulación es una técnica computacional que ayuda a efectuar esta selección, dando al ingeniero diferentes posibilidades que se adecúen a un problema en particular. Por un lado, se puede utilizar la simulación determinística para simular la producción de una operación y de esta manera elegir el equipamiento más adecuado tanto en perforación, carga y transporte. Por otro lado, se puede utilizar la simulación probabilística para simular modelos de carga y transporte con diferentes combinaciones de maquinarias para luego elegir el más apropiado según las características de la operación. Teniendo en cuenta esto, una herramienta que permite lograr ese objetivo es un programa de simulación donde se evalúe y determine computacionalmente cuál es el equipo óptimo. El trabajo de investigación a abordar en esta propuesta involucra el estudio y análisis mediante el uso de herramientas de simulación, de un yacimiento minero para obtener las características relevantes que permitan definir la maquinaria más adecuada.

    Visualization is the process of mapping data into visual dimensions to create a visual representation to amplify cognition. Visual representations are essential aids to human cognitive tasks. They are valued to the extent that they provide stable and external reference points upon which dynamic activities and thought processes may be calibrated and upon which models and theories can be tested and confirmed. The active use and manipulation of visual representations makes many complex and intensive cognitive tasks feasible. A visual representation is able to convey relationships among many elements in parallel and provides an individual with directly observable memory. A successful visualization allows the user to gain insight into the data, i.e. to communicate different aspect of the data in an effective way. Even with today’s visualization systems that give the user a considerable control over the visualization process, it can be difficult to produce an effective visualization. To obtain useful results, a user had to know which questions to pose; problems had to be framed in very precise terms. A strategy to improve this situation is to guide the user in the selection of the parameters involved in the visualization. Our research goal is the design of a visualization system that assist the user in the construction of the visualization, by considering the semantic of the data, the semantic of the stages through all the visualization process and the semantic of the external elements affecting the visualization.

    Despite the known health benefits of regular participation in physical activity people still refuse this practise. Nowadays, Virtual Reality (VR) is a very powerful and compelling computer tool by which humans can interface and interact with computer-generated environments. In this paper, we propose a virtual training system which can be customized for the physical activity level of the user. System provides real time visual action guide and a performance’s feedback of users through a Natural User Interface (NUI). We conduct a brief pilot study to evaluate our virtual trainers in which participants’ performance doing physical activities is evaluated via our NUI. Initial results indicate that virtual training through a NUI is motivating and entertaining for any kind of user, in particular for individuals with low level of physical activity.

    Fue implementado un ambiente virtual de aprendizaje siguiendo algunos principios de la Educación a Distancia, para auxiliar las clases presenciales de Física. Para su construcción fueron investigadas las herramientas y técnicas más adecuadas. Los recursos que el ambiente presenta posibilitan la organización de las informaciones de forma eficiente, estimulan la interactividad y manipulación de los contenidos a través del desarrollo de actividades adecuadas (lecturas, testes online, simulaciones de fenómenos físicos de difícil visualización), así como permiten un aprendizaje auto-controlado. La evaluación del ambiente por alumnos durante el año 2002 indica que su utilización contribuye para establecer las condiciones necesarias para alcanzar un aprendizaje significativo en la sala de clases. Following the guidelines of distance education, a virtual learning environment was implemented to aid physics classrooms lessons. For its construction, the appropriated tools and techniques were explored. The resources within the environment allows an efficient organization of the information, helps to stimulate the interactivity and the manipulation of the contents through the development of adequate activities (readings, online tests, physical phenomena of difficult visualization simulations), as well as a self-controlled learning. The evaluation of the environment made by the students during the year 2002 indicates that it contributes to establish the necessary conditions to reach a significant learning in a classroom.

    The paper presents a work executed in the virtual prototyping area. It is described as a procedure for the implementation of a CNC (Computerized Numeric Command) lathe prototype using software for virtual environment development. This procedures focus mainly on the interlocking system (functionality) and geometric model (physical design) of the lathe. Consequently, this work aims at checking the potential and limitations of this graphic interface tool, considering the complexity of the data required for product prototyping in manufacturing or assembly.

    Virtual Reality has become, once again, a popular and interesting topic, both as a research and commercial field. This trend has its origin in the use of mobile devices as computational core and displays for Virtual Reality. Android is one of the most used platform in this context and Unity3d is a suitable graphic engine for such platform. In order to improve the immersive experience, some electronic devices, Arduino especially, are used to gather information, such as the movement of the user's arms or legs. Although these three elements are often used in Virtual Reality, few studies use all of them in combination. Those who do, do not develop a reusable framework for their implementations. In this work we present AnArU, a framework for physical human interaction in Virtual Reality. The goal of AnArU is to allow an easy, efficient and extensible communication between electronic devices and the Virtual Reality system.

    La manera en la que las personas interactúan con las computadoras no es siempre la misma. A medida que la tecnología avanza se desarrollan nuevas herramientas, nuevas propuestas de interacción emergen y se crean nuevas interfaces. Las interfaces de Realidad Aumentada constituyen un ejemplo de tal desarrollo. Las mismas ofrecen al usuario un entorno combinando, por un lado, información del mundo real, y por otro, información sintética creada y manejada por la computadora. Una correcta fusión de estos dos mundos en un único entorno e inferfaz de usuario es un elemento esencial en todo sistema de Realidad Aumentada. Las distintas áreas de aplicación de estos sistemas poseen cada una sus propios requerimientos. En este artículo presentamos las diferentes líneas de investigación relacionadas con Realidad Aumentada que están actualmente en desarrollo en nuestro laboratorio.

    La representación tridimensional de grandes volúmenes de datos de terreno requiere un gran número de polígonos y de texturas, significando un problema la transmisión por red de los modelos. El enfoque multiresolución permite la transmisión progresiva, es decir, la transmisión de un modelo básico de baja resolución seguido de refinamientos sucesivos hasta completar la resolución deseada. En este trabajo se presenta un nuevo modelo multiresolución denominado Bitree geométricotexturado que, a diferencia de trabajos previos en el área de modelos multiresolución, representa tanto la geometría como la textura de un tetTeno. Se plantea la aplicación del análisis multiresolución de la transformada Wavelet en el modelo Bitree. Además, se propone una arquitectura cliente-servidor Java y un algoritmo de transmisión progresiva de los modelos por Internet.

    Una de las tareas importantes involucradas en el proceso de minería es la selección adecuada del equipo o maquinaria a utilizar durante dicho proceso. Estos equipos difieren según el trabajo que realicen, y para ello deben ser seleccionados de manera tal que se logre obtener el mayor beneficio y eficiencia de cada uno de ellos. La importancia de esta tarea radica en que durante el proceso minero intervienen muchas variables técnicas, geométricas (características propias del yacimiento) y económicas. Además existen muchas marcas, modelos y tamaños de equipamientos que compiten y que muchas veces entregan resultados similares a los realmente esperados por el usuario. Actualmente el ingeniero que efectúa la selección no cuenta con una herramienta automática confiable y apropiada para evaluar estos equipos y decidir cuál de ellos es mejor para su proyecto. Generalmente esta tarea se realiza a “mano” en función a la experiencia. Dicha tarea de selección se facilitaría si en lugar de hacerla manualmente, se dispusiera de un programa que conociendo las características de los equipos disponibles en el mercado y las condiciones de trabajo permitan realizar en forma automática la mejor selección. La simulación es una técnica computacional que ayuda a efectuar esta selección, dando al ingeniero diferentes posibilidades que se adecúen a un problema en particular. Por un lado, se puede utilizar la simulación determinística para simular la producción de una operación y de esta manera elegir el equipamiento más adecuado tanto en perforación, carga y transporte. Por otro lado, se puede utilizar la simulación probabilística para simular modelos de carga y transporte con diferentes combinaciones de maquinarias para luego elegir el más apropiado según las características de la operación. Teniendo en cuenta esto, una herramienta que permite lograr ese objetivo es un programa de simulación donde se evalúe y determine computacionalmente cuál es el equipo óptimo. El trabajo de investigación a abordar en esta propuesta involucra el estudio y análisis mediante el uso de herramientas de simulación, de un yacimiento minero para obtener las características relevantes que permitan definir la maquinaria más adecuada.

    Visualization is the process of mapping data into visual dimensions to create a visual representation to amplify cognition. Visual representations are essential aids to human cognitive tasks. They are valued to the extent that they provide stable and external reference points upon which dynamic activities and thought processes may be calibrated and upon which models and theories can be tested and confirmed. The active use and manipulation of visual representations makes many complex and intensive cognitive tasks feasible. A visual representation is able to convey relationships among many elements in parallel and provides an individual with directly observable memory. A successful visualization allows the user to gain insight into the data, i.e. to communicate different aspect of the data in an effective way. Even with today’s visualization systems that give the user a considerable control over the visualization process, it can be difficult to produce an effective visualization. To obtain useful results, a user had to know which questions to pose; problems had to be framed in very precise terms. A strategy to improve this situation is to guide the user in the selection of the parameters involved in the visualization. Our research goal is the design of a visualization system that assist the user in the construction of the visualization, by considering the semantic of the data, the semantic of the stages through all the visualization process and the semantic of the external elements affecting the visualization.
