A realistic CG billiards simulation can be accomplished when based on a physical foundation which provides data for a 3D simulation. Artificial opponents are always a welcome addition when it is a challenging opponent. This paper reports on our approach to develop such a simulation. To achieve the required accuracy when computing the shots and ball motion we used as a starting development point the...
The use of virtual reality in training and simulation as well as the use of haptic feedback are already used in many areas such as medicine, aviation, and training in controlled environments, such as training firefighters. The purpose of this study was the creation of a virtual multisensory environment for the simulation of a training task used in the training of firemen, with the added purpose of...
In recent years, the e-sports (electronic sports) phenomenon has been a growing trend and, with it, the interest in online videogames by players and spectators has also risen. One of the most popular genre of games is the MOBA (Multiplayer Online Battle Arena). Similarly to traditional sports, during a match there are several types of events that are of interest to players, coaches and analysts. These...
Creating a mobile urban tourism storytelling application presents several interactivity challenges on how to convey an engaging multimedia experience on-site. This article describes a methodology for fast prototyping of a multimedia mobile applications dedicated to urban tourism storytelling. The application can be a game that takes advantage of several location-based technologies, freely available...
Predicting buildings degradation and erosion by natural and artificial phenomena has been an unexplored area. In this article is presented natural and artificial phenomena simulations applied to a tridimensional model, using physics mechanics, created algorithms and using materials, which aims to be used to predict buildings level of destruction in the next years.
With the increase in the number of students worldwide, it has become difficult for teachers to track their students or even the institution itself to identify anomalies in degrees and courses. A viable option that allows following the evolution over the years, could be the analysis of academic data. However, analyzing such data without pre-processing can be a task that requires a high cognitive effort...
In this article it is presented and described the process of design, development, implementation and validation of the Middle Tagus Hospital Center's website. It was intended to create a communication and disclosure tool of important and helpful information, it would be to meet the needs of users and health professionals. The website should respond to current technological issues, particularly those...
Despite the historical limitations associated with the study of marine species, current technology enhances pocean animal data collection. Such data is crucial in a variety of contexts, both scientific and commercial. In fact, with a variety of tagging and tracking devices, it is relatively easy to gather information on marine species. Such information is nowadays present in large amounts, often in...
A methodology to rapidly produce environments that combine the intuition of in situ augmented reality (AR) with the commodity of virtual reality (VR) is proposed in this paper, by bringing together unmanned aerial systems (UAS) imagery and procedural modelling. While fully synthesized environments provide a very accurate visualization of the conserved parts of the real-world, missing parts — namely...
The traditional attitude towards user interfaces has changed. The Post-WIMP era has brought about novel input modalities such as touch, tangibles or gestures that allow users to manipulate digital contents more intuitively. These novel input modalities make use of the users' innate skills instead of imposing the learning of new interaction techniques. Nonetheless, there has not been a systematic evaluation...
Computer technology continuously evolves at an incredible pace, with today's machines being barely recognizable when compared to the first computers ever created. Despite this, and in spite of the many advances in human-machine interactions, the main method for interfacing with computers has remained the same for several decades. Tangible User Interfaces (TUI) are an interesting alternative to the...
Historical and cultural building conservation is nowadays limited to high value buildings and only receive financial support when serious issues arise. HeritageCARE project is willing to shift this mentality, towards "prevention is better than the cure". New technologies are able to support such motivation by improving building inspector work during their inspection routine. In that regard,...
