En la era digital el plagio académico ha alcanzado nuevas características y una preocupante dimensión, siendo el ciberplagio su manifestación más agravada. Esta práctica deshonesta se ha enraizado entre el estudiantado universitario a la hora de realizar sus trabajos académicos. Es un fenómeno complejo, con múltiples elementos asociados e interrela...
We propose a new architecture for 3D information systems that takes advantage of the inherent parallelism of the GPUs. This new solution structures information as thematic layers, allowing a level of detail independent of the resolution of the meshes. Previous proposals of layer based systems present issues, both in terms of performance and storage...
Being able to effectively use online tools has become a fundamental competence in our Society. Therefore, it is important to tackle the age digital divide as there is a rapidly growing number of elderly people. Like everyone else, older adults (senior citizens or the silver generation) must be equipped with the necessary skills to be able to be con...
We discuss the reasons that explain that our world needs actions that favor active aging, as well as the initiatives that have driven the universities to try to favor it. We focus on the importance of research in the University Programs for Seniors in Spanish universities and present the main actions that the University Program for the Elderly of t...
Everything is now done online: reading newspapers, talking to friends and relatives, paying invoices and taxes, setting up doctor appointments, etc. As such, competences related to the use of Information and Communication Technologies (ICT) are fundamental. In particular, as mobile technologies and devices such as smartphones or tablets become more...
Elderly people can suffer some degree of decline in their cognitive capacities, usually including different symptoms (decreased problem solving capacity, decreased ability to reason and to maintain focus, forgetfulness, etc.). Cognitive stimulation has been shown to decrease the rate of intellectual decay and potentially reverse age-related cogniti...
La mayoría de Universidades para Mayores ofrecen en sus programas la formación en el uso de las Tecnologías de la Información y Comunicación para sus alumnos, pero, en los últimos años, los avances en nuestra sociedad sobre la utilización de estas tecnologías están haciendo necesarios ciertos cambios en las acciones formativas que los alumnos solic...
Life expectancy is growing. So there is an equally growing need to fully integrate senior citizens in the Knowledge Society where ICT tools play a crucial role.
With the advent of mobile devices this problem was aggravated, as more and more information, communication and formal duties are being designed and processed for that context.

Conventional information systems are frequently used to document Cultural Heritage sites. These systems are adequate for some specific purposes as they can store and retrieve a large amount of heterogeneous documents.
Nevertheless, this is not enough for research and conservation purposes; researchers need to be able to find out relations between d...
User interaction experience has been lately the main focus of the industry of entertainment. High rendered graphics and huge computing process have been lagging behind for paving the way to the user experience interaction in which the way the user gets involved with the system is a key point. For this reason, we present along with this paper an enh...
Geographic information systems (GIS) allow us to manage information related to a territory in an efficient and flexible way. Management of information concerning cultural heritage presents a set of requirements which are similar to those. In processes such as documentation, restoration and preservation it is necessary to locate a wealth of informat...
Work on archaeological sites or cultural heritage artefacts usually generates a huge amount of heterogeneous information. The strong spatial structure of data suggests that this information should be linked to a threedimensional model of the artefact. This paper presents a new approach to the representation and management of information in the Cult...
En este trabajo se aborda el problema de la detección de inclusión y el cálculo de distancia a la superficie en modelos poligonales de varios cientos de miles de polígonos. Este problema es especialmente importante en el contexto de la interacción con dispositivos hápticos, presente en aplicaciones de realidad vütual tales como sistemas de entrenam...

3D digitalization has become a common tool in archaeology. However, the post processing of the data produced by the scanners is still quite complex, and the computer models generated are given very few practical applications.
In this paper, we analyse the key steps involved in the processing of the point clouds. We also review some of the more usu...
One of the most important problems nowadays in virtual archaeology is the fact that scanning real models produces huge amount of polygons, and these polygons must be rendered and displayed in a interactively way, trying to minimize the hardware requirements.
In a global world, internet has become the most important way of knowledge, and archaeology...
Large-range laser scanners provide a huge number of points that are not so easy to handle with laptops and current commercial software. Each laser capture can have several million points, and usually it is needed more than one to retrieve the complete surface. These digitalization devices are used for scanning large areas like buildings, walls or g...

In this paper we present a new data structure: the BP-Octree (Bounding-planes Octree). The BP-Octree is based on a spatial decomposition of the model using an octree, and offers a very tight hierarchy of convex bounding volumes which leads to simplified models. It is done by assigning to each node of the tree a set of planes that, intersected one a...
En este artículo presentamos una introducción al problema de la generación de modelos 3D a partir de datos obtenidos mediante escáner láser, analizando brevemente los trabajos más significativos dentro de este campo. A continuación proponemos un sistema cuya finalidad es la semiautomatización del proceso completo. Para ello, el sistema se apoya en...
En el presente trabajo se presenta una nueva estructura de datos que permite representar un solido mediante una jerarquía de planos espacialmente indexados. Se hace uso de un árbol para realizar la jerarquizacion tridimensionalmente indexada. Los planos que correponden a los nodos de dicho nivel forman una envolvente convexa del sólido en el volume...
Space-Partition Octree (SP-Octree) is a hierarchical representation scheme for solid modelling. It allows a multiresolution representation of polyhedral objects, and has been successfully used in progressive transmission. Moreover, this scheme allows visualising the model in an adaptive way. However, at intermediate levels of the SP-Octree, the obt...

In the last years several 3D model compression methods for multiresolution applications have been presented, most of them using 3D meshes. Octrees are a natural multiresolution representation scheme, although it is approximate. Extensions of classical Octrees that represent polyhedral object exactly have been proposed. One of them are the SP-Octree...
The ray-scene intersection test is the most costly process when a scene is rendered. This process may be improved using any strategy to be able to speed-up it. Generally, any strategy used is based on the building of a spatial indexing in the scene domain or in the rays domain. However, there is no theory to formalize these techniques. In this pape...
Extensions to classical Octrees that add new types of terminal nodes have been proposed for the exact representation of polyhedral objects. In this work, we present a new solid representation scheme using Octrees which include boundary information of the represented object in the internal nodes of the tree. In this way, basic operations with the mo...
This paper describes the design of an object oriented rendering system. The system has been designed as part of a research project whose goal is to investigate the influence of different aspects of the rendering process on the quality of the resulting image.

The basic aim of UISEL is to leverage processes of independency and individual empowerment of Senior Citizens through the use of mobile devices that allow an almost ubiquitous access to the information and communication. Beyond raising awareness for the benefits of person aged 50+ in using this equipment, this project intends to achieve practical apprenticeship by this target group on how to take the best advantages out of it. The benefits for the senior citizens can be huge, regarding fiscal obligations and social security issues, localization in case of emergency situations, medical monitoring and control, combating isolation, while simultaneously contributing to leisure and time occupation. This aim will be achieved through the definition, development and implementation of a two-stage learning methodology:
1. A training phase based on immersion in mobile contents and a multimedia environment which requires collaborative efforts from the transnational groups of trainees. This stage is destined to trainers and caretakers that are in direct contact with senior citizens. It will take place through a blended learning methodology integrating f2f sessions and mobile multimedia contents with the support of an e-platform for collaboration and communication
2. The transfer of the mobile technology appropriation to the senior citizens. This will be achieved through direct training by the trainers and caretakers with support of mobile multimedia modules that will also have a self-learning model so that senior citizens can, later on, recall how to use any of the mobile devices functionalities.
