- AR Mobile Application to Enhance the Birdwatching ExperiencePublication . Venâncio, José; Marto, Anabela; Ascenso, Rita Margarida Teixeira; Rodrigues, Nuno; Gonçalves, Alexandrino José MarquesGuard@Lis application was developed to ease the birdwatching activity. The main purpose was to support the discovery and identification of bird species along a trail, encouraging the preservation and protection of nature. To create a new bird observation perspective since augmented reality features were developed to enhance the experience of birdwatching, ensuring the chance to watch even the most elusive birds. Adding animated 3D models of some birds allows the observation of these species that, for several reasons, may not be easy to encounter in their natural habitat when the user is making the trail. The solution is composed of a multiplatform app and a back-office. It is prepared to create routes with hotspots and improve the bird species list. This first version was designed with a route in the city of Leiria, having specific points along the way, defined for the observation of certain species. Guard@Lis application intends to encourage the didactic and educational facets, so the whole development process of this application was to create a guide that allows users to be able to identify and list the number of bird species found. At this stage, the app allows its users to trail the main historical and tourist points of Leiria and collect the bird species observed.
- A virtual reality UAV simulation with body area networks to promote the elders life qualityPublication . Crespo, Andres Bustamante; Idrovo, Graciela Guerrero; Rodrigues, Nuno; Pereira, AntónioThe world population is aging, all countries are experiencing an increase of elder population. The pace of aging population in many developing countries is substantially faster than in the past. Consequently, these countries must adapt much more rapidly to this aging. Therapy and Physical activity helps to improve health and well-being in the elders, for it brings longevity and improves quality of life. Sport and physical activity have been used as a tool to improve life. The technology has been used to promote entertainment and sport through digital games with wireless technology. Wii games had a positive impact on the overall well-being of the elderly, compared to a control group that played traditional board games. Our proposal combines both, virtual reality and body area network for generate a fun application that allows the elderly to control a Unnamed aerial vehicle (UAV) in a completely virtual environment using only the movement of his arms.
- A User-Centred Well-Being Home for the ElderlyPublication . Rodrigues, Nuno Carlos Sousa; Pereira, AntónioEvery single instant a person generates a large amount of information that somehow is lost. This information can assume a large diversity of means, such as an oral word, a sneeze, an increase in heartbeat or even facial expressions. We present a model which promotes the well-being of the elderly in their homes. The general idea behind the model is that every single experience may mean something, and therefore may be recorded, measured and even have adequate responses. There is no device that provides a more natural interaction than a human body and every one of us, sends and receives useful information, which sometimes gets lost. Trends show that the future will be filled with pervasive IoT devices, present in most aspects of human life’s. In this we focus on which aspects are more important for the well-being of a person and which devices, technologies and interactions may be used to collect data directly from users and measure their physiological and emotional responses. Even though not all the technologies presented in this article are yet mainstream, they have been evolving very rapidly and evidence makes us believe that the efficiency of this approach will be closely related to their advances.
- Reconstruction and generation of virtual heritage sitesPublication . Rodrigues, Nuno; Magalhães, L.; Moura, J.; Chalmers, A.Traditionally procedural modelling techniques are commonly used to generate new structures and are presently established in several areas such as video games and computer animated movies. However they may also be used in heritage applications to efficiently produce models of non-existing worlds for which there is some kind of knowledge (e.g. floor plans, photographs) to support the reconstruction of realistic environments. Similarly they may also be used to support the generation of distinct possibilities that allow experts to draw some conclusions or conceive different hypotheses about lost worlds. The present paper shows the benefits and constraints that may arise from the use of such techniques in virtual heritage applications. Furthermore, a whole method is proposed, for the reconstruction and generation of virtual heritage traversable house models, provided through the means of a grammar, demonstrated with the reconstruction and generation of several Roman houses from the heritage site of Conimbriga, Portugal.
- Conimbriga as paradigm of cultural heritage (virtual) recriationPublication . Gonçalves, Alexandrino; Rodrigues, Nuno; Hipolito-Correia, VirgilioA preservação dos espaços de herança cultural da Humanidade tem sido uma das áreas de maior utilização da computação gráfica. Este artigo apresenta uma metodologia de trabalho expedita e de baixo custo que visa a recriação virtual destes espaços históricos, que por via da disponibilização dos mesmos na web, permite a sua análise e estudo por parte dos especialistas, bem como o seu acesso ao público em geral, contribuindo desse modo para um maior conhecimento da nossa história.
- Simulador de UAV para la mejora de la calidad de vida de los adultos mayoresPublication . Bustamante, Andres; Guerrero, Graciela; Rodrigues, Nuno; Pereira, AntónioEste artículo presenta el desarrollo de un simulador de realidad virtual para la gestión de un Vehículo Aéreo No Tripulado, enfocado a mejorar la calidad de vida de las personas adultas. La presente investigación ha recogido características de gestos y movimientos físicos de usuarios realizados por otras investigaciones relacionadas con el fin de estudiar la misma interacción dentro de un mundo virtual. A través de esta investigación se generó un menor número de gestos, mejorando la curva de aprendizaje del usuario sin afectar la usabilidad. La implementación siguiente utiliza una arquitectura clienteservidor, compuesta de 2 dispositivos Raspberry Pi, y un Smartphone que actúa como un servidor, la comunicación entre ellos se logró mediante el uso de la tecnología de Baja Energía Bluetooth. La inmersiva experiencia virtual se logra utilizando Unity 3D y Google VR, herramientas que permitieron el diseño y visualización de un ambiente virtual lúdico como un enfoque para promover las habilidades físicas y cognitivas como el pensamiento espacial y la coordinación mano-ojo. Al realizar maniobras a través de un circuito aéreo lleno de obstáculos, el simulador de UAV propuesto fomenta la actividad motora y mental mientras se está entreteniendo al usuario. El resultado es la mejora de la calidad de vida del usuario evitando el sedentarismo cognitivo y físico.
