The Mind-Mirror: See Your Brain in Action in Your Head Using EEG and Augmented Reality

Résumé

Imagine you are facing a mirror, seeing at the same time both your real body and a virtual display of your brain in activity and perfectly superimposed to your real image "inside your real skull". In this paper, we introduce a novel augmented reality paradigm called "Mind-Mirror" which enables the experience of seeing "through your own head", visualizing your brain "in action and in situ". Our approach relies on the use of a semi-transparent mirror positioned in front of a computer screen. A virtual brain is displayed on screen and automatically follows the head movements using an optical face-tracking system. The brain activity is extracted and processed in real-time with the help of an electroencephalography cap (EEG) worn by the user. A rear view is also proposed thanks to an additional webcam recording the rear of the user's head. The use of EEG classification techniques enables to test a Neurofeed- back scenario in which the user can train and progressively learn how to control different mental states, such as "concentrated" versus "relaxed". The results of a user study comparing a standard visualization used in Neurofeedback to our approach showed that the Mind-Mirror could be successfully used and that the participants have particularly appreciated its innovation and originality. We believe that, in addition to applications in Neurofeedback and Brain-Computer Interfaces, the Mind-Mirror could also be used as a novel visualization tool for education, training or entertainment applications.
