Physically disabled and mentally challenged people are an important part of our society that has not yet received the same opportunities as others in their inclusion in the Information Society. Therefore, it is necessary to develop easily accessible systems for computers to achieve their inclusion within the new technologies. This paper presents a project(More)
The proposed work is part of a project that aims at the control of a videogame based on hand gesture recognition. This goal implies the restriction of real-time response and the use of unconstrained environments. In this paper we present a new algorithm to track and recognise hand gestures for interacting with a videogame. This algorithm is based on three(More)
Hands-free interfaces could be the best choice for Human-Computer Interaction (HCI) for people with physical disabilities that are not capable of using traditional input devices. Once a first prototype is developed in the laboratory taking into account design and usability requirements, real users is what finally categorize an interface as useful or not.(More)
The recognition of emotional information is a key step toward giving computers the ability to interact more naturally and intelligently with people. This paper presents a completely automated real-time system for facial expression's recognition based on facial features' tracking and a simple emotional classification method. Facial features' tracking uses a(More)
In this paper, we present a robust real-time 3D tracking system of human hands and face. This system can be used as a perceptual interface for virtual reality activities in a workbench environment. The main advantage of our system is that the human, that is in front of the virtual reality device, do not needs any type of marker or special suite. The system(More)
This paper presents an affective model that determines the emotional state of a character according to the personality traits and the experienced emotions. We consider an emotional state as the layer between personality and emotion. The proposed affective model offers a mapping between emotions and emotional states. To evidence emotional states of a virtual(More)
Perceptual user interfaces are becoming important nowadays, because they offer a more natural interaction with the computer via speech recognition , haptics, computer vision techniques and so on. In this paper we present a visual-based interface (VBI) that analyzes users' facial gestures and motion. This interface works in real-time and gets the images from(More)
We describe a robust real-time 3D tracking system of the extreme limbs of the upper human body, i.e., the hands and the face. The goal of the system is that it can be used as a perceptual interface for virtual reality activities in a workbench environment. The whole system includes an input capture and calibration module, a real time color segmentation(More)
