A mind-controlled switch is described, which comprises input circuitry for receiving mind state data from a first external device, an actuator, responsive to user actuation to set one or more threshold mind state values, and control circuitry for controlling a second external device in dependence on the mind state data and the mind state value(s). Notably, the mind-controlled switch is provided separately both from a first external device (which actually collects the mind state data from the user) and the second external device, which is the device being controlled by the switch. Accordingly, the second external device need not have its own mind-controllable functionality, but can instead be a conventional device which is imbued with this functionality by way of the separate mind-controlled switch.

In at least some embodiments, the present disclosure describes an electroencephalography (EEG) device having a main band and at least one moveable band. The main band may include fixed EEG sensors positioned on the main band so as to contact a scalp of the wearer in at least two scalp zones. The at least one moveable band may include at least one moveable EEG sensor. The moveable band may move relative to the main band to adjust to a position of the moveable EEG sensor(s) on the scalp of the wearer in at least one adjustable zone. The EEG device may include a processing device to measure EEG measurements using the fixed and/or movable EEG sensors, and transmit the EEG measurements to an external computing device to determine a mental condition, a mental state or both of the wearer based on the EEG measurements.

An information processing apparatus includes a retaining unit, an image acquisition unit, an image processor, a comparator, and an image generator. The retaining unit is configured to retain a defined attachment position being an attachment position of a biological detection sensor with respect to a body site of a user, the defined attachment position being defined in advance. The image acquisition unit is configured to acquire a capture image captured by an imaging unit. The image processor is configured to extract, from the capture image, a body shape of the user. The comparator is configured to compare the body shape with the defined attachment position. The image generator is configured to generate, based on a comparison result by the comparator, a display image to be displayed on a display unit.

Systems and methods according to which a plurality of dipoles embedded within a simulated human brain of a simulated human head are stimulated with electricity. In one or more embodiments, the electricity with which the plurality of dipoles are stimulated is based on a recording of an animate human head. In one or more embodiments, stimulating the plurality of dipoles with the electricity causes the simulated human head to generate one or more electromagnetic properties that simulate same of the animate human head. In one or more embodiments, the one or more electromagnetic properties are detected from the simulated human head via: a first non-invasive technique; a second non-invasive technique that is different from the first non-invasive technique; or both the first non-invasive technique and the second non-invasive technique. For example, the one or more electromagnetic properties may be detected via both the first and second non-invasive techniques simultaneously.

One variation of a system for locating electrodes on a head of a user includes a headset defining a set of electrode bodies elastically interconnected by a unique set of spring elements configured to locate the set of electrode bodies at electrode positions of the international 10-20 standard, irrespective of the size of the head of the user. The spring elements are configured to carry electrical signals between interconnected electrode bodies and ultimately to a controller. An electrode tip is mechanically and electrically coupled to each electrode body. The electrode tip comprises a thin conductive probe mounted at the distal end of an elastic beam and is configured to extend from a base of the electrode tip, bypass hair, and electrically couple to the head of the user, and an insulative boss, configured to rest on and transfer the weight of the headset to the head of the user.
