EUROGRAPHICS'10: A Mobile Augmented Reality System to Enjoy the Sagrada Familia
Gimeno, Jesús; Pardo, Fernando; Morillo, Pedro; Fernández, Marcos
(2010). ArticleSAFAR is a mobile Augmented Reality application that makes possible to see in real-time the ‘Sagrada Familia’ as it will look like when it be finished. The application successfully integrates outdoor tracking and 3D rendering processes to provide an augmented view of this under construction monument to city travellers, equipped with Nokia mobile phones. This outdoor tracking process includes a custom skyline detection algorithm, which provides real-time tracking and avoids not only external calibrations, but also additional sensors connected to the mobile phone. Moreover, the occlusion problem of the resulting images are improved by means of predefined drawings sequences, which control the...

The application successfully integrates outdoor tracking and 3D rendering processes to provide an augmented view of this under construction monument to city travellers, equipped with Nokia mobile phones. This outdoor tracking process includes a custom skyline detection algorithm, which provides real-time tracking and avoids not only external calibrations, but also additional sensors connected to the mobile phone. Moreover, the occlusion problem of the resulting images are improved by means of predefined drawings sequences, which control the combination between computer-generated and displayed video images. The performance evaluation results show that both the outdoor tracking and the 3D rendering techniques combined in SAFAR requires relatively low computational load, while providing a proper accuracy.

IPCV'09: A Device-Independent 3D User Interface for Mobile Phones Based on Motion and Tracking Techniques
Gimeno, Jesús; Morillo, Pedro; Coma, Inmaculada; Fernández, Marcos
(2009). ArticleThe user interaction in mobile phones has been traditionally based on key behaviors that users have adapted around their mobile devices.

The user interaction in mobile phones has been traditionally based on key behaviors that users have adapted around their mobile devices. Although this type of interaction could be suitable for some contents, it could be improved from the point of view of the usability. In this paper we present a new user interface based on 3D navigation oriented to mobile phones. To enhance the user experience, we have developed a new interface based on 3D real-time graphics where users interact by means of natural movements of their devices. The goals of this development consist in enhancing the user interaction and accessibility to web content or interactive multimedia applications by means of avoiding a key-based, or a mouse-based, navigation and proposing a software solution adaptable to multiple and different mobile devices. In this sense, the user inputs can be detected by different input devices such as accelerometers or cameras, as well as the traditional keypads. Since mobile phones with on-board digital cameras are now widely available at low cost, the proposed 3D user interface exploits the acquisition capabilities of these input devices. In this sense, a differential algorithm has been applied in order to estimate phone movements from video images. The results of the performance evaluation of the 3D user interface shows that the proposed algorithm not only obtains a motion and tracking under extreme lighting conditions, but also adds an insignificant overhead to the system performance. Finally, a 3D environment has been designed to evaluate the performance of the presented approach, which has been successfully tested in actual users.

Además de esto, se crearan algunas aplicaciones de prueba donde se comprobará si el sistema desarrollado realmente funciona. Estas aplicaciones comprobarán el funcionamiento tanto en Single-Touch como en Multi-Táctil. Esta tecnología está siendo utilizada cada vez más por industrias debido a que se están produciendo grandes avances en ella, lo que le permite ser un perfecto complemento a los demás periféricos (ratón, teclado, botones, etc..) en los casos donde estos no cumplen con las expectativas que en un principio se espera de ellos. Todo esto hace que cada vez sea más aconsejable su implantación en sistemas de uso cotidiano.

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). ArticleThe 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.
