    Proyecto completo.

    Aplicación para dispositivos móviles programada en Java, concretamente sobre la plataforma J2ME (MicroEdition) cuya finalidad es la recopilación de toda la información que podemos encontrar cuando sucede un incidente de tráfico. La principal ventaja de utilizar un dispositivo móvil, como por ejemplo un teléfono móvil, es que podemos usar las características multimedia (cámara de fotos, video, GPS, etc) y añadirlas al informe final y enviarlo al instante.

  • ISC'08: Virtual Prototyping and Multi-Modal Interfaces to Test the Control of an Orthosis

    Pujana-Arrese, Aron; Gimeno, Jesús; Landaluze, Joseba; Fernández, Marcos

    (2008). Article

    Full article.

    The test of wearable robots with users can be dangerous, especially initially, when the control algorithms and the controller are tested. The use of virtual prototypes, as opposed to creating real ones, whilst not eliminating the need to manufacture an ultimate prototype for the final tests, eliminates intermediate tests which could potentially be dangerous for a user. Multi-modal interaction and virtual prototyping are used to test and evaluate the controllers. The Ikerlan research centre has designed a 2 DoF arm orthosis to research the issue of the interaction of such devices with the environment. This orthosis was not physically constructed, but a virtual prototype was created for...

    The test of wearable robots with users can be dangerous, especially initially, when the control algorithms and the controller are tested. The use of virtual prototypes, as opposed to creating real ones, whilst not eliminating the need to manufacture an ultimate prototype for the final tests, eliminates intermediate tests which could potentially be dangerous for a user. Multi-modal interaction and virtual prototyping are used to test and evaluate the controllers. The Ikerlan research centre has designed a 2 DoF arm orthosis to research the issue of the interaction of such devices with the environment. This orthosis was not physically constructed, but a virtual prototype was created for testing the performance of the different control algorithms implemented.. The multi-modal interfaces considered are composed of traditional devices, one haptic device (Phantom) and a video-based motion capture and mark recognition system. As a result, two test platforms have been developed, where the orthosis is tested in Real-Time simulation based on the real movements of the user. Augmented Reality (AR), Virtual Reality (VR) and videobased optical motion capture techniques are used in order to evaluate a prototype.

  • Jorevir'08: Técnicas de captura de movimiento, infrarroja y basada en vídeo, aplicadas al prototipado virtual de una ortesis

    Gimeno, Jesús; Pujana-Arrese, Aron; Coma, Inmaculada; Fernández, Marcos; Landaluze, Joseba

    (2008). Article

    Articulo completo.

    En este artículo se describe la inclusión de técnicas de captura de movimiento ópticas para el diseño y evaluación de un prototipo de ortesis. Las técnicas aplicadas son de dos tipos: basadas en infrarrojos para la captura de movimientos del usuario en el estudio de patrones de movimiento para el diseño de la ortesis; y basadas en vídeo para la evaluación de los algoritmos de control sobre el prototipo virtual diseñado. El prototipo de la ortesis es totalmente virtual, utilizando programas comerciales de simulación física y dinámica, en combinación con dos aplicaciones de prueba implementadas utilizando Realidad Virtual (RV) y Realidad Aumentada (RA).

  • HSI'08: BIOMIMO Design & Test: Motion Capture and AR Techniques to Design and Test an Orthosis Prototype

    “BIOMIMO Design & Test” is a software application to aid the process of designing and testing IADs (Intelligent Assist Devices), also known as orthoses, developed by the Ikerlan technology centre. This software combines Augmented Reality (AR), Virtual Reality (VR) and videobased optical motion capture techniques in order to evaluate a prototype without actually constructing it, and to avoid the risk of testing it on a real person. Initially, it is applied to a 2 DoF (degrees of freedom) arm orthosis. This paper, in a first instance, describes the orthosis designed, and the position/force control strategies implemented. It then goes on to describe the motion capture system used as a way of...

It then goes on to describe the motion capture system used as a way of human-computer interaction and the software developed. The controllers were tested using the virtual prototype, taking as data input the movement of a real user and interacting with a virtual wall. Some results are presented as well.

  • Elevation Cable Modeling for Interactive Simulation of Cranes

    García fernández, I.; Pla Castells, M.; Martínez Durá, R. J.

    (2008). Article

    SCA '08: Proceedings of the 2008 ACM SIGGRAPH/Eurographics Symposium on Computer Animation 2008, 1-10 In this paper, the way to simulate hoisting cables in real time is addressed. We overcome instability in such simulation by considering a two-layered model: a model for the dynamics of a cable passing through a set of pulleys and an oscillation model based on the classical one-dimensional wave equation. The first layer considers the interaction between the cable and pulleys with the elevation equipment, while the second layer simulates cable oscillation. Numerical instability is avoided by suspending the oscillation layer when required. Due to the system properties, this can be carried out...

    SCA '08: Proceedings of the 2008 ACM SIGGRAPH/Eurographics Symposium on Computer Animation 2008, 1-10 In this paper, the way to simulate hoisting cables in real time is addressed. We overcome instability in such simulation by considering a two-layered model: a model for the dynamics of a cable passing through a set of pulleys and an oscillation model based on the classical one-dimensional wave equation. The first layer considers the interaction between the cable and pulleys with the elevation equipment, while the second layer simulates cable oscillation. Numerical instability is avoided by suspending the oscillation layer when required. Due to the system properties, this can be carried out in such a way that does not cause significant loss in the system quality. It considers the oscillation of the cable between every pair of pulleys, collision detection and the variation of the cable length very efficiently. Rendering issues are discussed, with remarks on how to prevent aliasing artifacts in the cable. Efficiency is analyzed, including performance tests which show that the model can be run very efficiently. The paper also covers how to integrate the model in a complex multibody simulation with a high degree of interactivity.

  • Physically-Based Interactive Sand Simulation

    Pla Castells, M.; García Fernández, I.; Martínez Durá, R. J.

    (2008). Article

    Eurographics 2008 - Short Papers, 21-24. 2008 The interactive simulation of 3D terrains has been approached from several perspectives. Due to the complexity of the system involved, most of the models proposed focus on a visually realistic animation of the scene, rather than on a physically-based accurate simulation of a granular system. Those models lack generality when interacting with the environment; in most cases, no reaction forces are computed, considering only soil deformation. This limitation reduces their usability in applications such as driving simulators. We propose the use of a theoretical discrete model that considers normal forces for 3D real-time simulation of granular...

This limitation reduces their usability in applications such as driving simulators. We propose the use of a theoretical discrete model that considers normal forces for 3D real-time simulation of granular systems. We also extend this model to consider horizontal forces, allowing a wider range of interactions. Several numerical tests have been implemented and detailed results have been analyzed which show a good model performance.
