This article describes an environment based on the user's physical location to tell interactive stories on mobile devices. First, the technology to physically locate the user is presented. Thence the project, called MPISTE, is put into context with related projects. The paper continues with the description of the project and its design as part of a project to develop an affective virtual guide. The...
This paper presents the application of Hidden Markov Models and Artificial Neural Networks to recognise trajectory patterns in a Euclidean space from data filtered and parametrised by the Fast Fourier Transform. The data comes from the movement of a device based on accelerometers which is used by the Nintendo Wii.
Video games are ubiquitous in modern day life. Unfortunately, several children are overweight or even obese because they spend a lot of time watching television or playing non-physical video games, instead of perfoming physical activities. Furthermore, this lack of exercise affects their development. The fact that children are becoming overweight or obese is a health concern for many countries that...
This paper proposes and explores a novel approach to express emotions in cyberworlds through a flock of virtual beings. Emotions are represented in terms of the arousal and valence dimensions and they are visually expressed in a simple way through the behaviour and appearance of the individuals in the flock. In particular, the arousal value parameterizes the Reynolds' flocking algorithm, and the valence...
