In the last two decades, an increasing number of techniques, known as tone mapping operators (TMOs), have been developed to reproduce high dynamic range (HDR) imagery on traditional displays. Despite having recently emerged TMOs taking into account the specific characteristics of different display devices, none of these algorithms has been specifically developed for small screen devices (SSDs).
Thus, in this thesis a study concerning the visualization of HDR images on SSDs was carried out, regarding the proposal of solutions to improve their visualization. Initially a review and evaluation of currently existing TMOs showed that the SSDs with limited size, resolution and colour-depth, require a specific investigation to find or create appropriate solutions. This study also allowed identifying a set of TMO characteristics that need to b...
The creation process in digital art relies often on collaborations between an artist (or group of artists) and a multidisciplinary team. This collaboration implies a multidisciplinary work involving art, science, technology, design, psychology, etc. that come together by sharing a common communicational and informational space.
In this essay we bring into discussion how the creation process cycle in digital art could be instantiated and applied for the development of serious games through end-user purposes of both creative authors: the digital artists and the serious games developers. We realise a comprehensive analysis of this creation process in digital art, specially the aesthetic musing activity, while devising how it could be helpful to introduce new engaging stimulus in the creative process of serious games.

The theme of this report is information visualization. Nowadays, this is a very active
and vital area of research, teaching and development. The basic idea of using computer
generated pictures to gain information and understanding from data and relationships is the
key concept behind it. This is an extremely simple, but very important concept which is
having a powerful impact on methodology of engineering and science.
This report is consisted of two parts. The first one, is an overview of the subtle
correlation between the visual techniques, the user perception and the data. In the second part,
several computer applications, tools, projects and information visualization systems are
analyzed. In order to categorize them, seven basic types of data are considered: onedimensional,
two- dimensional, three-dimensional, multidimensio...
This work aims the creation of virtual worlds by working teams with resource to advanced interaction techniques, such as speech commands and gestures, as well as the resource to portable devices. The physical characteristics of virtual reality environments lead us to a different kind of user interfaces. However, we found some usefulness on the classic WIMP paradigm, which we also apply by using a PDA, in order to complement the interaction possibilities. In terms of application description we use the Virtual Reality Modeling Language. One of the main goals is the separation/combination of VRML files in order to allow the work to be cared out individually by the members of the team, and later combine the results to produce the global virtual world.
The Trans Portugal Galicia Network
Project, TORGA.net, was a proposal
to the Program Interregional IIIA,
Galicia – North of Portugal sub-program with the following partners: University of Minho, University of Vigo, Centro de Supercomputación de Galicia and the Centro de Computação Gráfica in Guimarães. It has as its main objective the creation of infrastructures and the organization and development of the space beyond borders.
The project proposes to establish a broadband communication network with reduced operational costs that links the campuses of the Universities
of Vigo and Minho, as well as their associated Technological Centers, which are the Supercomputación de Galicia and the Centro de Computação Gráfica in Guimarães.
Using this telecommunications infrastructure, Access Centers will be installed in a Technology Access G...
Cultural heritage is an extremely valuable set of materiality, traditions and knowledge from the Past that should be used to better understand the Past itself. However, even nowadays there are still some difficulties to manage, preserve and disseminate cultural heritage sites. The usage of multimedia technology and 3D environments in cultural heritage has reduced these difficulties; nonetheless, there are still some remaining problems. In the last years, some multimedia technology and 3D environments have been applied to the cultural heritage in Portugal. A few of them are used for scientific research purposes and others are used for dissemination purposes. In this article, the authors will refer to some representative Portuguese case studies using Virtual Environments to maintain, preserve and promote Cultural Heritage. A critical rea...
