The “Junta de Comunidades de Castilla-La Mancha”, through the “Centre of Free Software (CESLCAM)”, has launched an innovative pilot project, GeoInfo CLM, which facilitates through mobile access information about Albacete and his fair. This project has born of LibreGeoSocial project developed by GSyC/LibreSoft group of the Universidad Rey Juan Carlos de Madrid. LibreGeoSocial is a project based on free software that allows the creation of social networks mobile with augmented reality interface. At the moment, LibreGeoSocial is the only FLOSS engine available about augmented reality.

The project has a mobile client application that allows you to use Android mobile phone for obtain the information about monuments, exhibitions, activities, restaurants, hotels or shops about Albacete and its fair. Users can also introduce geo-located information using text, images, audios or videos and share it with other users. Visitors to the fair can learn this technology through the volunteers of the City of Albacete, which will be located at different points of information authorized by the fairgrounds. The volunteers provide Samsung Galaxy S for the demos.

GeoInfo CLM, a pilot project of the CESLCAM, has enjoyed the cooperation of the City of Albacete, III Centennial Foundation, the Foundation Science and Technology Park of Albacete, GSyC/LibreSoft group of the Universidad Rey Juan Carlos, Escuela Superior de Informática de Ciudad Real, Publik, Telefónica, and ViveAlbacete as a diffuser of the project.

During the past 15^th and 16^th of June at Barcelona was celebrated the W3C Workshop: “Augmented Reality on the Web”.

“This W3C Workshop was held to discuss whether and how the exciting opportunities offered by Augmented Reality can benefit from Web technologies. Augmented Reality on the Web was hosted in Barcelona by Escola Tècnica Superior d’Enginyeria de Telecommunicació de Barcelona (ETSETB) at Universitat Politècnica de Catalunya (UPC). It attracted over 40 attendees and 22 papers. The participants represented a broad range of businesses including telecom operators, device manufacturers, AR content and platform developers, AR users from the advertising world, academics and standards bodies.”

GSyC/LibreSoft was invited to participate in the event thanks to their experience with LibreGeoSocial regarding social networks and augmented reality. During the event, GSyC/LibreSoft exposed the paper: “Mobile Augmented Reality browsers should allow labeling objects”, and a presentation about the needs of allowing users to tag the reality with augmented reality technologies. Also, a live demonstration of LibreGeoSocial was made, about the capabilities of tagging the real world.

The experience was very interesting because it was a workshop organized by the W3C. It was focused in the importance of using standards for augmented reality, a good opportunity to point to FLOSS solutions to achieve this goals.

Recently, we have added a new feature to LibreGeoSocial platform to extend the usability of our MAR (Mobile Augmented Reality) engine. We can sub-divide this feature in two sub-features. The first one analize and compare the images to find similar image. Using SURF technologies we can obtain several key points of the image that are distinctives and relevants. These points are invariant to the size, orientation or rotation, so the algorithm can find the original image although the image taken has not the same size, orientation or rotation. The second feature shown in the video is the possibility to anchor virtual images on a real picture. The image is analyzed in the mobile itself and looking for ways similar to a picture or photograph (like square or rectangle). This analysis is done in real time and keeps the tracking of the geometry shape to anchor the virtual information on real information.

Currently, we are studying new ways to analize and compare thousand the images in a small time. 

This system has multiple uses in tourism, museums, publicity, online publicity and other sectors where it is your imagination . The video shown all these features in action. Remember activate the subtitles to get more information about the system.
