With explosive penetration of portable electronic devices (PEDs) recent focus into consumer EEG devices has been to bring advantages including localized wireless interfacing, portability, and a low-cost high-performance electronics platform to host the processing algorithms to bear. However, most development continues to focus on brain-controlled video games which are nearly identical to those created for earlier, more stationary consumer EEG devices and personal EEG is treated as of a novelty or toy. According to embodiments of the invention the inventors have established new technologies and solutions that address these limitations within the prior art and provide benefits including, but not limited to, global acquisition and storage of acquired EEG data and processed EEG data, development interfaces for expansion and re-analysis of acquired EEG data, integration to other non-EEG derived user data, and long-term user wearability.

The invention discloses a shopping decision-making method based on brain-computer interaction. The method can determine the user's preference for a commodity on the basis of EEG signal data of the user selecting an item in the e-commerce platform, and is applied to a commodity recommendation function of the e-commerce platform. The method comprises the following steps: acquiring the EEG signal data of the user through an EEG device and recording and storing the EEG signal data; using a band pass filter and the independent component analysis method to preprocess the EEG signal data, and performing extracting to obtain the sample entropy; obtaining a feature vector based on the sample entropy, using the Naive Bayes method to identify different emotions, and setting the excitement level for each of different emotions; using the average energy ratio method to extract features, and performing normalization to obtain a concentration value; and finally obtaining the matching degree when the user browses a corresponding commodity according to the excitement level and the concentration value, setting a threshold Th, comparing the matching degree and the threshold Th, and recommending the corresponding commodity to the user according to the comparison result. The method improves the shopping experience and shopping efficiency of the user, and facilitates selection.

A device for measuring and/or stimulating a brain activity, preferably an EEG device, comprising means for transmitting and/or detecting physiological signals produced by the brain of an individual, and a support for the transmission and/or detection means, wherein the support is configured to extend over the top of the individual's head, the support comprising means for removably attaching to an accessory intended to be worn by the individual, on his or her head, such as an audio headset, the support being configured such that, when the device is worn by the individual, the means for transmitting and/or detecting physiological signals are held in substantially close contact with the individual's head by the accessory.

Theinvention discloses a conscious disturbancecerebral cortex status detection system, which comprises a brain response signalsynchronous collection module, a response signal noise processing module and a cerebral cortex status detection algorithmmodule. The response signalsynchronous collection moduleincludesatranscranial magnetic stimulationand magnetic-compatible EEG device, wherein an EEG capis a 64-channel high-density EEG cap,a transcranial magnetic stimulation coil is an 8-shaped coil. During implementation, the coil is arranged at the dorsolateral prefrontal areaof the left side of the patient(position of F3 electrode on the 10-20 EEG system) in a direction in which the magnetic field is perpendicular to the scalp. The conscious disturbancecerebral cortex status detection system and method fill the void of the conscious disturbancecerebral cortex status detection system and method. Compared with the current clinical research methods, the conscious disturbancecerebral cortex status detection system and method are cost-effective, convenient, simple in calculation, very applicable and suitable for clinical promotion.

This invention relates to a device that is intended to synchronize electroencephalograms (EEGs), recorded by any digital equipment, to physical events (sensorial, visual or auditory stimuli) and behavioral events (motor response, vocal response), in order to allow EEG signal mediation for the purpose of visualizing Evoked Potentials or Event-Related Potentials, which are important research subjects in the neurosciences and clinical investigations into neurological and psychiatric pathologies. This invention allows any digital EEG device to be transformed into equipment that can record Evoked Potentials. This invention also provides a method for analog synchronization of EEGs with oscillating electric light-related events and motor behaviors.

A method and system for tracking visual attention is disclosed. By generating at least one visual stimulus having a characteristic modulation applied to a high spatial frequency (HSF) component of the visual stimulus, and displaying the or each visual stimulus via a graphical user interface (GUI) of a display, a response may be evoked in the brain of a user. By receiving a neural signal of a user from a neural signal capture device, such as an EEG device, a point of interest of the user may be determined (when the user views a visual stimulus) based on the neural signal, since the neural signal includes information associated with a characteristic modulation of the visual stimulus directed by a visual attention of the user.
