System With Wearable Sensor For Detecting Eeg Response
A system in which a head-mountable wearable device detects a real-time electroencephalographic (EEG) response from a user while the user is performing an activity or exposed to an external stimulus in a real-world (non-clinical) setting. The wearable device performs on-board processing of a detected EEG signal to enable efficient data wireless transfer to a processing unit (e.g. on a smartphone or the like). The processing unit transforms the EEG signal in real time into a meaningful indicator of current mental state, and presents indicator to the user, e.g. in a form able to improve their performance of the activity, promote complementary activities or to enhance or alter their mental state.

- 1. A system comprising:
a head-mountable wearable sensor comprising:
a sensor array arranged to detect an electroencephalographic (EEG) signal from a user wearing the wearable sensor;
a filter module arranged to recognise and remove artefact waveforms from the EEG signal to generate a filtered EEG signal; and
a communication unit wirelessly transmitting the filtered EEG signal; and
a processing unit arranged to receive the filtered EEG signal transmitted from the head-mountable wearable sensor, wherein the processing unit comprises an analyser module arranged to generate, based on the filtered EEG signal, output data that is indicative of mental state information for the user, and wherein the wearable sensor is incorporated into headgear worn by the user exposed to a real world and/or virtual reality external stimulus, whereby the output data provides real-time mental state information for the user while exposed to the external stimulus.
