Sistema computacional interativo para tratamento de estresse por meio de aquisição de sinais biológicos

Abstract

Acquisition system and processing of biologics signal provide a way no invasive and no medicinal for realization of psychophysiology’s interventions. By signal means respiratory, of skin temperature, of galvanic response of the skin, electromyographic, electrocardiographic or electroencephalographic captured to treat similar pathology like stress, lack of concentration, anxiety, insomnia, strengthening and muscle relaxation. This paper address to present a proposal of computational system able to collect different signals and interact with the user by virtual environment that modify according with signal alteration and the individual evaluated. For this, the developed system associate with the equipment system to detection of this signals. And the end of the dissertation was made experimental evaluation of the functionalities to validate it and tests with voluntaries that had the objective to demonstrate an efficacy of this system. The system showed any efficient in attendance of the demands proposed and the voluntaries related facility in comprehension the functionalities, as well as in interaction with the virtual environments developed for the purpose of biofeedback.
