Title
(EN) EEG BRAIN-COMPUTER INTERFACE PLATFORM AND PROCESS FOR DETECTION OF CHANGES TO MENTAL STATE
(FR) PLATEFORME D'INTERFACE CERVEAU-ORDINATEUR D'ECG ET PROCEDE DE DETECTION DES MODIFICATIONS DE L'ETAT MENTAL
Abstract
(EN)
A system for a brain-computer interface (BCI) is provided. The system
comprises
an output unit configured to trigger a series of mental tasks for the patient,
a device having
a plurality of electrodes to continuously capture real-time raw
electroencephalography
(EEG) data from a patient, a server, and a display device to display and
update an
interface with visual elements based on issued control commands from the
server. The
server has an acquisition unit configured to receive the electrode data, a
processor
configured to detect real-time changes in brain-state of the patient in
response to the
series of mental tasks for the patient, a presentation unit configured to
generate visual
elements for an interface in real-time, and a display controller configured to
issue control
commands to update the interface using the generated visual elements. The
processor
detects the real-time changes in brain-state using the electrode data. The
processor is
configured to generate a set of features based upon a frequency domain
analysis of the
EEG data, reduce the dimensionality of the set of features by implementing a
feature
clustering process to account for redundancy in EEG signal features of the EEG
data, and
classify the features into a mental state.
