To identify physiological states that are predictive of a person's performance, a system provides physiological and behavioral interfaces and a data processing pipeline. Physiological sensors generate physiological data about the person while performing a task. The behavioral interface generates performance data about the person while performing the task. The pipeline collects the physiological and performance data along with reference data from a population of people performing the same or similar tasks. In various implementations, the physiological states are brain states. In one implementation, the pipeline computes bandpower ratios. In another implementation, the pipeline decomposes the physiological data into frequency-banded components, identifies brain states derived from the decomposed data—for example, clusters of correlations of decomposed data envelopes—grades the performance data, compares the graded performance data to the brain states, and identifies statistical relationships between the brain states and levels of performance.

The present invention relates to an electric current stimulation device capable of selectively stimulating a region including: a main body; an electrode unit which is equipped to the main body to contact at least a part of a user's body; and a control unit which controls the electrode unit to transfer a microcurrent of 1 mA or less by a Cranial Electrotherapy Stimulation (CES) method, wherein the control unit determines at least one stimulation area required to be stimulated in whole area of the user's brain according to a type of the user's diseases and determines at least one of two or more of first electrodes required to be activated (ON) in a plurality of electrodes, an intensity of the microcurrent which respective electrodes of the first electrode should induce and a route thereof in order to treat the disease focusing the microcurrents on the stimulation area. Accordingly, the present invention allows intensively treating a more accurate area in an appropriate level and providing a more efficient treatment environment to the stimulation area.

A vehicle includes a plurality of sensors mounted on a seat, an output device, and a controller. The controller is configured to obtain an acceleration in each of a first seat in contact with a driver's back and a second seat in contact with a driver's thigh through the plurality of sensors, to determine a specific frequency in each of the first seat and the second seat, to determine contact pressure information and load information of each of the first seat and the second seat through the plurality of sensors, to determine a human vibration sensitivity using at least one of the specific frequency, the contact pressure information, and the load information, to determine driver's emotional information including positive emotional information and arousal emotional information based on the human vibration sensitivity, and to control the output device according to the driver's emotional information.

Systems and methods for adjusting a user's circadian rhythm are provided. In some embodiments, a system may be configured to obtain information relating to the user's present circadian rhythm and information relating to one or more anticipated times of sleep and/or wakefulness. The system may generate a model for estimating the user's circadian rhythm. The system may also generate a model for estimating the user's homeostatic sleep drive. Based on one or both models, the system may generate instructions for activating the light source to adjust the user's circadian rhythm.

A system and method for therapeutic stimulation using virtual objects and gamification, in which multi-modality stimulus is applied using some combination of virtual elements, attention is enhanced by virtue of the user's active participation, and long-term use is encouraged by virtue of the entertaining nature of the gamification.

A method and system for detecting and removing EEG artifacts is disclosed herein. Each source of a plurality of sources for an EEG signal is separated for a selected artifact type. Each source of the plurality of sources is reconstituted into a recorded montage and an optimal reference montage for recognizing the selected artifact type of each source. The sources with artifacts are removed and the remaining sources are reconstituted into a filtered montage for the EEG signal.
