Description
Technical field
The present invention relates to field of electric control, be specifically related to control electronics.
Background technology
The concept of brain-computer interface starts from 1973, and it sets up between human or animal's brain and external equipmentDirectly connecting path. Since the seventies in last century, along with the development of Neuscience and computer technology,Brain-computer interface has made great progress. At present, the difference of the mode of obtaining according to brain signal, brain-computer interface canBe divided into intrusive mood and non-intrusion type, directly electrode be implanted to and in skull, be called intrusive mood BCl; Obtain from scalpThe number of winning the confidence is called non-intruding BCl. Nao electricity Shi brain cell colony provides the macroscopic appearance that produces of electricity, when greatlyWhen cerebration, can produce specific EEG signals. For intrusive mood brain-computer interface because electrode is inserted greatlyBrain, can directly extract from cerebral cortex the EEG signals that signal to noise ratio is higher. But connect for non-intruding brain machineMouthful, conventionally obtain EEG signals by wearing the modes such as electrode cap, infrared imaging, function nuclear magnetic resonance.
Due to the research of non-intrusion type BCl, only need to be direct on corticocerebral surface by specific equipmentCarry out the acquisition and processing of EEG signals, and do not need to carry out operation, therefore non-intrusion type is BCl alwaysStudy hotspot. Non-intrusion type BCl is because the temporal resolution of EEG signals (EEG) is high, and collecting device toolHaving easily the advantage such as carry, easy to use, is a kind of brain-computer interface mode of practicality. Invade based on the non-of EEGEnter formula BCl, can be divided into according to neuro-physiology mechanism: based on the BCl system of the imagination of moving, based on eventThe BCl system of related potential, the BCl system based on VEP etc.
In recent years, the correlative study of brain-computer interface had obtained very large development, brain-computer interface brain science,Neuscience, biomedical engineering, information, the fields such as control science have all produced a lot of application.

Rely on separately the realization of the motion imagination to needUser is carried out to training for a long time, and very strong to user's dependence.
Along with popularizing of intelligent mobile terminal (SmartPhone and SmartDevice), people are to letterThe serious hope of breath picked-up is further strong, and expectation can be obtained various information whenever and wherever possible. But existing intelligent mobile eventuallyHold as mobile phone and PAD, although small and exquisite, when operation, need this intelligent mobile terminal of user's finger contacts to carry out,Head deflects into the screen orientation of intelligent mobile terminal, and needs eyes to pay close attention to this end while operating alwaysEnd. Therefore, if need to walk, be engaged in various work or carry out recreation in operative intelligenceWhen mobile terminal, still can produce inconvenience, not only affect people's notice, and can cause certainPotential safety hazard.
