Workflow and brief description during enforcement
1, principal mode
Electroencephalogram acquisition mode by standard, the electrical activity of brain that records from experimenter's scalp, after prime amplifier amplification and A/D conversion become original brain electricity time series data, enter computing machine: 1. present original waveform, be equivalent to the with no paper electroencephalograph function of standard; 2. carry out signature analysis to understand this experimenter's electrical activity of brain pattern; 3. carry out real-time signature analysis and become the characteristic time sequence data, directly produce corresponding Brain Bites, or the music that control is adjusted by the computing machine generation is a brain control music, and control is by the graph image of computing machine generation, the result is presented to the experimenter, make it after the training of certain hour, can initiatively adjust brain activity,, thereby reach the purpose of feedback training so that above-mentioned musical sound and graph image change by experimenter's wish.
The port number of eeg signal acquisition is made as the 1-4 passage temporarily, adopts the more possibility of hyperchannel number after not getting rid of further research, as 16 passages, 32 passages or the like.The content of feedback presents together or presents separately in conjunction with the vision picture based on Brain Bites or brain control music, and sound and picture change with experimenter's electrical activity of brain.The content of picture can be coloured picture, the abstract dynamic coloured picture of simple animation, dynamic scene, innervation, also can be recreation of finishing certain task or the like.Presenting of statement then is mainly used in the state of pointing out the current brain activity of experimenter, finishes the feedback training task to help the experimenter to focus one's attention on.
Needed hardware is mainly a prime amplifier and a multimedia computer, then is luxury as configuration Advanced Videos equipment, and effect will be better.
When carrying out brain electricity feedback training, at first should analyze experimenter's electrical activity of brain pattern, to determine a comparatively suitable feedback training scheme.The experimenter should loosen body and mind as far as possible, and a darker quiet environment is necessary, and the operator should have certain psychology knowledge and skills, can instruct the experimenter at any time.The experimenter generally can reach control to a certain degree and the adjustment to own brain activity after repeatedly training.But the variation of periodic review experimenter electrical activity of brain pattern.
2 types
Except that above-mentioned functions, mainly increased brain-computer interface interface module.Brain-computer interface Study of Interface is a brand-new bio-engineering research field, be exactly that research is how with brain activity rather than with certain a part of operation as operational computations machines such as hands of body in brief, the simplyst be exactly research and how come mouse beacon to move, and the letter that computing machine is presented etc. is selected towards the direction of wanting to move with idea.Result of study uses a computer and will be very big Gospel for the residual patient of vast limb.
This type is mainly used in research, and therefore the programmed environment of an opening additionally is provided, and makes the researcher can work out suitable algorithm voluntarily.
3 family expenses are pocket
Be the simple miniaturization of principal mode, hardware is made in the very little circuit board box, gathers 1 passage EEG signals and gets final product, and signal analysis and figure sound generate by Single-chip Controlling, also can make integrated circuit board and insert computing machine by Computer Processing.Directly plug into after the user buys back home televisor in the family is stained with recording electrode by the household and can begins feedback training on its scalp.There is the user of computing machine can purchase the integrated circuit board that inserts computing machine, finishes feedback training on computers.Feedback look, listen content elder generation simple designs, from now on can be complicated gradually with the development of hardware technology.
By contrast, the utility model has following characteristics and innovation:
1. the theory that clear and definite EEG signals are used for biofeedback training is proposed, with not Frequency of brain wave composition with information is brought into play the training effect as feedback information, and principle is clear and definite.
2. use up-to-date digitlization brain wave acquisition technology so that this machine system stability is anti-dried Immunity can be strong.
3. the information feedback material purpose that provides is strong, and content is popular, is fit to Chinese state Feelings.
4. instrument has different model, the principal mode that namely has suitable appropriate authority to use, also have through The domestic type of Ji material benefit more has to can be used for the further flatbed of research.
5. be visible musical with the EEG signal real-time transform, and should dynamic music application In biofeedback training, be to propose first. From in fact clear and definite sphere of learning keyword The implication of " Brain Bites " (brain music), and first proposition " brain control music " (brain-controlled music) and " visual Brain Bites " (visual brain Music) concept is also given complete explanation.
Social effect of the present utility model is:
1 social demand: along with the aging of Social man mouth, dog-eat-dog, various non-device matter Property and organic brain dysfunction such as serious neurasthenia, intractable aypnia, obsession, hot-tempered Strongly fragrant disease, notice lax, decrease of memory, apoplexy and postencephalitis, epilepsy, excessive drinking and The sub-health states such as drug abuse, bringing human misery needn't say more, extensively also not the having of its involvement aspect Any Other diseases can be compared. Traditional treatment is to act on central nervous drugs as primary and secondary work With greatly, use for a long time easy resistance or habituation. Brain electricity biofeedback therapy provides a kind of safe and efficient Non-medicine training adjustment means.
2 development meanings: EEG signals is used for biofeedback high-tech area owned by France, and difficulty is very big, and domestic product-free still, foreign products be a family only also, and so poor performance is not seen widespread use still.The brain electricity biofeed back instrument that this project is developed has not only been filled up domestic blank, from theory and technical also near the forward position, the world in this field.Along with the operation of domestic type brain electricity biofeedback training instrument, can allow extensive patients receive cheap convenient and safe supplemental training means efficiently, will become brain dysfunction patient's Gospel.The achievement in research of brain-computer interface will directly make vast physical disabilities person be benefited, and greatly improve their quality of life.Its influence is difficult to estimate.
