Abstract: A system in which a wearable device detects an electroencephalographic (EEG) response from a user during sleep-related activity, e.g. trying to fall asleep, being asleep or waking up, and outputs an audio signal that is tailored, based on the EEG response, to enhance the user's sleep experience. In particular, an audio, thermal and/or olfactory signal may be used to facilitate any one or more of (i) a smooth path into REM sleep, (ii) a reduced potential for sleep being disturbed, and (iii) exit from sleep at an optimum time. In one example, the system synchronizes properties of an audio signal comprising a dominant white and/or pink noise component with the identified sleep-related parameters. The synchronized properties can include any of intensity, frequency, tone, volume and rhythm.

Abstract: 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.

Abstract: A biofeedback system capable of obtaining a real-time EEG response “in the field”, i.e. while a user is performing an activity in a real-world (non-clinical) setting, and capable of transforming the EEG response into a meaningful indicator of current mental state, and presenting that indicator to the user, e.g. in a form able to improve their performance of the activity. The system comprises a wearable sensor incorporated into headgear worn by the user during participation in an activity. A central processing unit is arranged to receive an EEG signal transmitted from the wearable sensor, and filter and analyse the EEG signal to generate output data that is indicative of mental state information for the user.
