Resumo(s)
Na última década, com a comercialização para o grande público de aparelhos
portáteis de EEG e outros sensores que registam a atividade fisiológica, aplicados à
indústria da saúde e dos vídeo jogos, potenciou-se o recurso ao registo neurofeedback
proporcionando a sua utilização nas mais diversas formas de arte. Em consequência do
interesse por estas novas abordagens, surgiu a escolha deste projeto, o qual visa a
exploração do potencial do EEG em contexto artístico, nomeadamente na sua aplicação
à música e à imagem. A proposta baseia-se no desenvolvimento de uma performance
interativa centrada na relação ação/reação dos estímulos originados pela música,
permitindo aos três agentes, compositor, intérprete e espectador, interagirem em tempo
real. Neste sentido, foi necessário criar um sistema interativo com o recurso a um
equipamento da Emotiv EPOC EEG que permitisse a captação da atividade neuronal do
espectador, em tempo real, com a intenção de controlar eventos musicais e eventos
gráficos, através de um patch construido no software Max/MSP. Para o
desenvolvimento do projeto foram definidos dois estudos, em que cada um deles propõe
a realização de experiências com diferentes participantes, sendo o objeto do primeiro
estudo a análise e recolha de dados da atividade neuronal provenientes de estímulos
musicais, e do segundo estudo à verificação do funcionamento de todo o sistema
interativo idealizado para a futura performance.
In the last decade, due to the commercialization to the general public of portable EEG and other sensors that record the physiological activity, related to health industry and video games businesses, an increasing use of neurofeedback record took place, providing its use in several art forms too. As a result of the interest aroused by these new approaches, it was made the decision of choosing this project, which aims at exploiting the potential of EEG in an artistic context, particularly in its application to music and image. The proposal is based on the development of an interactive performance focusing on action/reaction of the stimuli generated by the music, allowing the three agents, the composer, the performer and the spectator to interact in real time. Therefore, it was necessary to create an interactive system, using an Emotiv EPOC EEG equipment that could allow the capture in real time of the viewer’s neuronal activity, with the goal of controlling music and graphic events, through a patch built in Max/MSP. In order to develop this project, two studies were defined, each one proposing the conduction of several experiments with different participants; the object of the first study is to analyse and collect data of neuronal activity from musical stimuli; and the second is to check the functioning of the interactive system designed for the future performance.
