Systems including wearable electroencephalography devices with movable band(s) and methods of use thereof

A method, comprising:

• measuring, by at least one processing device of an electroencephalography (EEG) device, at least one set of EEG measurements, the at least one set of EEG measurements comprising:
• a first subset of EEG measurements of at least two areas of a brain of a wearer using at least two fixed dry EEG sensors,
• a second subset of EEG measurements of at least one other area of the brain using at least one moveable dry EEG sensors;
• wherein the EEG device comprises:
• a first ear cup configured to fit over a first ear of the wearer;
• a second ear cup configured to fit over a second ear of the wearer;
• a main band attached to the first ear cup on a first side of the main band and the second ear cup on a second side of the main band;
• wherein the main band comprises the at least two fixed dry EEG sensors of a plurality of EEG sensors;
• wherein the at least two fixed dry EEG sensors are positioned on the main band so as to contact a scalp of the wearer in at least two scalp zones so as to detect EEG measurements associated with the at least two areas of a brain of the wearer;
• a first moveable band pivotably attached to the first ear cup;
• wherein the first moveable band comprises the at least one moveable dry EEG sensor of the plurality of EEG sensors;
• and
• wherein the first moveable band is configured to:
• pivot relative to the main band and the first ear cup between a first location and a second location, wherein, at the first location, the first movable band parallelly overlaps the main band when viewed from a side of the main band, and wherein, at the second location, the first movable band and the main band form an angle when viewed from the side of the main band;
• and
• adjust to at least one position of the at least one moveable dry EEG sensor on the scalp of the wearer so as to result in contact between the at least one moveable dry EEG sensor and the scalp of the wearer in at least one scalp zone to detect EEG measurements associated with the at least one other area of the brain;
• establishing, by the at least one processing device, a communication link with a personal computing device;
• synchronizing, by the at least one processing device, a time reference of EEG measurements with the personal computing device, displaying a predetermined content;
• measuring at least one set of the EEG measurements during the display of the predetermined content, the at least one set of the EEG measurements comprising:
• a first subset of the EEG measurements of at the at least two areas of the brain using the at least two fixed dry EEG sensors,
• a second subset of the EEG measurements of at the at least one other area of the brain using the at least one moveable dry EEG sensors;
• and
• transmitting, by the at least one processing device, the time-synchronized EEG measurements to the personal computing device to facilitate the personal computing device to display an indication of a mental state of the wearer, the indication being derived from the at least one set of the EEG measurements.
