Embodiment
Fig. 1 is the process flow diagram of an embodiment of terminal media control method for playing back provided by the invention.As shown in Figure 1, the executive agent of following steps can have one or more modules, chip on the terminal of media play function for mobile phone, MP3, MP4, PAD etc.This terminal media control method for playing back specifically comprises:
S101, detection user's eeg signal;
Take mobile phone as example, when integrated when controlling the function of media play by user's brain wave in user mobile phone, can detect by the brain wave sensor established in the mobile phone eeg signal to the user.
Bio-electric phenomenon is one of essential characteristic of vital movement, and various biologies all have the performance of electrical activity, arrives greatly whale, and is little of bacterium, and strong or weak bioelectricity is arranged.In fact, English cell (cell) word also has the implication of battery, and countless cells just is equivalent to a miniature baby battery successively, is bioelectric source.
There are many neurocyte in activity in human brain, form the change of electrical equipment.That is to say have the swing of electrical equipment to exist.And this swing is presented on scientific instrument, seems just as fluctuation.We are referred to as brain wave electrical equipment vibrations in brain.
Can detect eeg signal by brain wave sensor, such as ThinkGear AM chip of the U.S. etc.
S102 determines user's the residing band information of eeg signal, and the residing band information of this eeg signal is used for this user's of reflection sleep state;
After the eeg signal that the user detected, can identify the residing band information of this eeg signal by the central control unit in mobile phone.Because the eeg signal of different frequency range can reflect the sleep state that the user is current, so just can know the state that the user is current by identifying the residing band information of this eeg signal.
Concrete, human brain is not producing brain wave all the time.The frequency variation scope between per second 1~30 time, can be divided into four wave bands usually: " α " ripple, frequency are 8-12Hz.Be in the state of mind of loosening fully when brain, or the brain wave that occurs when the mind is absorbed in." β " ripple, frequency are 14~30Hz.The brain wave situation that is the mankind under a kind of common, daily waking state of this ripple reflection.It is the fluctuation situation of brain under general waking state, and in this state, the practices such as logical thinking, analysis will appear in the people." θ " ripple, frequency are 4~8Hz.The initial stage of the sleep that the brain wave in this stage is behaved.Be that the people begins to feel that sleepiness is dim, the transitional region between entirely waking up and entirely sleeping, brain wave just becomes the speed motion with 4~8Hz." δ " ripple, frequency are 0.5~4Hz.The brain wave in the deep sleep stage that it is behaved.When the people entered sound sleep fully, brain was just with 0.5~4Hz motion, i.e. δ ripple.At this moment, people's breathing deeply, bradycardia, blood pressure and body temperature all can descend to some extent.Nowadays, related to every field for the application of brain wave technology, especially the application in areas of information technology is particularly extensive.
To sum up, can determine by detecting the residing band information of eeg signal user's sleep state.
S103, band information residing according to eeg signal carries out Play Control to the media play software of terminal.
Because the residing band information of eeg signal has reacted the current sleep state of user, specifically referring to the associated description in S102, therefore, sleep state that can be current according to the user, namely the residing band information of eeg signal by central control unit to the media play software of terminal carry out as: regulate volume, close the Play Control operation such as software.

S206, band information residing according to described eeg signal carries out Play Control to the media play software of terminal;
Concrete, if residing frequency range belongs to α wave band or beta band, described media play software is not carried out Play Control;
If the residing frequency range of the eeg signal that detects belongs to the θ wave band, the volume of media play software is turned down;
If the residing frequency range of the eeg signal that detects belongs to the δ wave band, close media play software.
Concrete, after central control unit is identified the residing band information of this eeg signal corresponding to above-mentioned digital signal, be built in tables of data in mobile phone by inquiry, the data that preset in the digital signal that obtains and mobile phone compared the eeg signal type that acknowledges receipt of.Operate accordingly according to different signal types again, in order to control the state of peripheral hardware.This operation comprises:
If judge that this brain wave is α or β ripple, illustrate that the user is in waking state, do not need media play software is carried out control operation.
If judge that this brain wave is the θ ripple, illustrate that user's consciousness is fuzzy gradually, but also there is no the penetration depth sleep state, can reduce the volume of mobile media this moment, specifically can be adjusted to 1/2 or 1/3 of original volume.
If judge that this brain wave is the δ ripple, illustrate that the user has entered deep sleep.All media play softwares that play in can closing hand phone this moment allow mobile phone enter into sleep state.Thereby protected user's the sense of hearing, also avoided mobile phone to play for a long time the situation that media cause electric weight to deplete simultaneously.
Further, the frequency of the digital signal of central control unit poll monitoring input can also be set, the brain wave type corresponding according to the current digital signal that monitors, the control operation of real-time renewal to media play software.
Terminal media control method for playing back provided by the invention, eeg signal by detecting the user is also determined band information under it, band information residing according to this eeg signal carries out Play Control to the media play software of terminal, guarantees that the human body sense of hearing is healthy, saves the mobile phone electric weight.
One of ordinary skill in the art will appreciate that: all or part of step that realizes above-mentioned each embodiment of the method can be completed by the hardware that programmed instruction is correlated with.Aforesaid program can be stored in a computer read/write memory medium.This program is carried out the step that comprises above-mentioned each embodiment of the method when carrying out; And aforesaid storage medium comprises: the various media that can be program code stored such as ROM, RAM, magnetic disc or CD.
