Attention Concentration Through Auditory Stimulation {System and Method for Enhancing Attention Concentration Through Auditory Stimulation}

A system and method for enhancing attention concentration to control stimulation.

Electroencephalogram (EEG) is a measurement of the current generated by the electrodes attached to the scalp when a person thinks or acts about something and uses the neurotransmitters at the synapses in the brain to transmit information. Means that.

These brain waves are delta waves (0.2-4 Hz), theta waves (4-8 Hz), alpha waves (8-13 Hz), beta waves (13-30 Hz), and gamma waves (30-50 Hz), in the order of low to high frequency, depending on frequency. Can be classified as). The EEG in each frequency band has different characteristics, which can be used to determine the state of mental activity and attention of a person. In particular, SMR waves (12-15 Hz) are brain waves representing a high concentration state, which is suitable for measuring attention.

Neurofeedback is a biofeedback technology that controls biosignals. The neurofeedback refers to a process of inducing an electroencephalogram device to generate an electroencephalogram in a desired direction by using a signal obtained by measuring an electroencephalogram generated in a user's brain. Neurofeedback is currently being used to improve brain-related potential or to improve clinical symptoms in patients.

However, this training has a limitation in that the efficiency of the training is largely influenced by ambient noise when only the visual stimulus is provided to the subjects with reduced concentration.

In addition, visual stimulation-based neurofeedback training to enhance concentration is often provided after the end of the training analysis of the subject's brain wave changes. Some service methods may provide feedback to the user via a real-time display (PC monitor, tablet PC, mobile phone, etc.). However, since the subject was able to monitor his brain wave changes only through the display, it was difficult to monitor the concentration of the subject while conducting personal activities such as study or work.

10 is a flowchart schematically showing the detailed steps of the neurofeedback control step of the attention concentration enhancement method according to an embodiment of the present invention.

Referring to FIG. 10, the neurofeedback control step (S400) according to an embodiment of the present invention includes a preprocessing step (S410) for performing preprocessing on the received brain wave data; SMR wave extraction step (S420) of extracting SMR waves from the pre-processed brain wave data; And generating a control signal for the signal for the auditory stimulus based on the extracted SMR wave (S430, S440). It includes.

In the preprocessing step (S410), preprocessing of the brain wave data of the user 10 measured in the brain wave measuring step (S300) is performed. The data received through the sensor includes noise and the like, and removes or processes signals that are not necessary for analyzing electroencephalogram data, such as power supply noise and electrocardiogram signals due to heartbeat, from the received brainwave data.

Thereafter, in the SMR wave extraction step (S420), SMR waves are extracted from the EEG data preprocessed in the preprocessing step (S410). SMR waves are brain waves corresponding to the frequency of 12Hz to 15Hz, the SMR wave extraction step (S420) can extract only the SMR waves by removing the brain waves from the SMR waves and the like through a filter.

Subsequently, in the control signal generation step, the SMR wave determination step (S430) of determining whether the SMR wave extracted in the SMR wave extraction step (S420) increases from the previous value based on the time input to the time controller (S430). Perform In an embodiment of the present invention, in the SMR wave determination step (S430), the state of attention concentration of the user 10 is determined by determining whether the extracted SMR wave is increased, and applied to the user 10 based on this. Losing control of auditory stimulation. In order to determine whether the SMR wave is increased, the SMR wave determination step (S430) calculates an average intensity of the first SMR wave based on the time received from the time controller 160. After calculating the average intensity of the second SMR wave based on the input time, the average of the first and second SMR waves can be determined. Afterwards, if the attention training continues, the average intensity of the SMR wave before the reference time and the average intensity of the SMR wave at the present time are compared to determine whether the SMR wave is increased.

For example, when using the attention-enhancing device for the first time, if the user sets the attention time to 20 minutes and the rest time to 5 minutes through the time controller, the intensity of the SMR wave is measured and the average value is calculated for 20 minutes. . Then, after measuring the intensity of the SMR wave for 20 minutes and calculating the average value, it is determined whether the intensity of the SMR wave is increased. The first time a user starts using the attention-enhancing device at t0, t1 is the attention-measuring time input by the user, the average of the intensity of the SMR waves measured from t0 to t1 is 60, and the SMR waves measured from t1 to t2. When the average of the intensity is 80, it can be seen that more SMR waves are output than in the SMR wave determination step (S430). On the contrary, when the average of the intensity of the SMR waves measured from t2 to t3 is 40, the average of the intensity of the SMR waves measured from t1 to t2 is reduced to 80. Therefore, it may be determined that the SMR waves are output less than before.

In this embodiment, the intensity of the reference SMR wave may be a value that is changed through the attention concentration reinforcement learning step of the user 10, rather than a fixed value.

When it is determined that the SMR wave extracted in the SMR wave determination step S430 is increased, an auditory stimulus reproduction signal generation step S440a is performed. In the auditory stimulus reproduction signal generation step (S440a), it is determined that the attentional force of the user 10 is maintained and generates a signal for continuously maintaining the auditory stimulus output in the auditory stimulus signal output step (S200).

When it is determined that the SMR wave extracted in the SMR wave determination step S430 is not increased, an auditory stimulus stop signal generation step S440b is performed. In the auditory stimulus stop signal generation step, it is determined that the user's attention is reduced and the break is necessary, and the auditory stimulus signal output step is generated by generating an auditory stimulus stop signal corresponding to the break time input by the user through the time controller. A signal for stopping the auditory stimulus output from the S200 is generated.

As described above, in the control signal generation step, by determining whether the extracted SMR wave is increased and generating a control signal corresponding thereto, EEG data measured in the brain of the user 10 through the EEG sensor 300 is measured. Using the neurofeedback training to induce to generate the EEG, in particular SMR wave in the direction desired by the user.
