In combination with the above technical features, the main effects of the method and system of brain wave analysis group concentration of the present invention will be clearly shown in the following embodiments.

Please refer to the first figure and the second figure first, which is a system for revealing the concentration of brain wave analysis in the embodiment of the present invention, so that one screen (51) of a monitoring terminal (5) displays the group concentration status and related information. Stored in a database (52) of the monitoring terminal (5), the brain wave analysis group concentration system comprises: a plurality of brain wave detectors (1), an brain wave analysis module (2), a focus In the embodiment, the brain wave detector (1) and the brain wave analysis module (2) can be integrated into a wearable wearable body (3) and an integrated module (4). The concentration comparison module (3) and the accumulation module (4) can be provided with operation and comparison functions by the processing module (53) of the monitoring terminal (5), wherein: the brain wave detector (1), all used to get a brain wave information. The brain wave detector (1) may include a delay switch for delaying the turn-on time (for example, 3 minutes, 5 minutes, etc.) to eliminate the case where the initial brain wave is not stabilized.

Referring to the first figure and the second figure, the brain wave analysis module (2) signal is connected to the brain wave detector (1) for analyzing one concentration value of each brain wave information. The brain wave analysis module (2) can be, for example, an EEG chip developed by Shennian Technology, which can process and output brain wave band data such as α, β, and can output an eSense focus index by a special algorithm. The eSense Focus Index can show the strength of the user's "concentration" or "attention", which ranges from 0 to 100. When you are upset, mentally paralyzed, inattentive, and anxious. The value of the concentration index will be reduced. However, the brain power chip is not limited to this, as long as it can process and output the brain wave band data such as α, β, and then analyze the concentration value of the brain wave information.

Referring to the second figure, the concentration comparison module (3) signal is connected to the brain wave analysis module (2) for comparing whether the concentration value of the brain wave information is lower than a preset concentration degree. Threshold value (31). The concentration threshold (31) is exemplified by the aforementioned eSense focus index, if the range of values If it is 0 to 100, the concentration threshold (31) can be set to 50 (other values can be set according to user requirements). If it is higher than 50, it can be judged as high concentration. Below 50, it can be judged as low. Focus.

Referring to the second figure, the cumulative module (4) signal is connected to the concentration comparison module (3) for the concentration value of the brain wave information to be lower than the preset concentration threshold (31). When a quantity value is accumulated, the quantity value is output to the aforementioned monitoring terminal (5). For example, it can be accumulated by using a counting function of a general processor or a programmed integrated module, and when the concentration value of brain wave information measured by one of the aforementioned brain wave detectors (1) is less than 50 , can be accumulated to 1, and then the brain wave information measured by the aforementioned brain wave detector (1) has a concentration value lower than 50, which can be accumulated to 2, and so on, but at an evaluation time (for example If the concentration value measured by the same brain wave detector (1) within 30 minutes, 1 hour, etc. is less than 50 again, it will not be re-accumulated to avoid repeated accumulation. In this way, the user can be assisted in quickly judging the group's concentration from the multi-person brainwave analysis data. However, the above statistical method is not limited thereto, and the cumulative module (4) can also be used to accumulate a quantity value when the concentration value of the brain wave information is higher than the preset concentration threshold value (31), and The quantity value is output to the monitoring terminal (5). For example, when the concentration value of the brain wave information measured by one of the aforementioned brain wave detectors (1) is higher than 50, it can be accumulated to 1, and then measured by a brain wave detector (1). When the concentration value of brain wave information is higher than 50, it can be accumulated to 2, and so on, but measured by the same brain wave detector (1) in an evaluation time (for example, 30 minutes, 1 hour, etc.) If the concentration value is higher than 50 again, it will not be re-accumulated to avoid repeated accumulation. This also allows the user to quickly determine the concentration of the group from the multi-person brainwave analysis data.

Please refer to the second figure. Preferably, the method further comprises a cluster module (6), and the signal is connected to the brain wave detector (1) and the brain wave analysis module (2) to filter the brain wave. The detector (1) is divided into multiple arrays, and each group is given a different identification code, so that the cumulative module (4) accumulates the quantity value of each group according to the foregoing identification code, and according to different groups Co-presented on one of the monitoring terminals (5) screen (51). For example, the grouping module (6) can be divided into four groups of 1, 10, 100, and 1000, each group including four aforementioned brain wave detectors (1), and then the cumulative module (4) Will be accumulated according to the aforementioned identification code The number of values for each group. Thereby, the accumulated quantity value can be presented on the screen (51) of the monitoring terminal (5), so that the user can quickly judge the current number of people in each group to know whether it is necessary to adjust the teaching mode or assist in discussion.

Referring to the second figure, preferably, a quantity comparison module (7) is further included, and the signal is connected to the accumulation module (4) for comparing whether the quantity value is greater than or equal to a preset warning threshold. The value (71), if yes, generates a cue signal to the aforementioned monitoring terminal (5). For example, when there are 4 members in each group, the alert threshold (71) can be set to 2. When the number of low concentration values is higher than 2, it can be judged that most members are not focused on group discussion or After class, you can judge that the group discussion is not effective or the lecture performance is not good, and provide a prompt signal (such as ringtone, flash or image, etc.) to prompt the user to intervene in group discussion or adjust the teaching method. Conversely, if the number of high-concentration values is higher than 2, it can be judged that most members focus on group discussion or class, and can also provide the above-mentioned prompt signals, so that the faculty members can add points and other teaching methods.

When the concentration value of brainwave information is less than 50, it can be accumulated to 2, and so on. However, the above statistical method is not limited thereto, and the cumulative module (4) can also be used to accumulate the foregoing quantity value when the concentration value of the brain wave information is higher than the preset concentration threshold value (31), and The quantity value is output to the monitoring terminal (5). For example, when the concentration value of the brain wave information measured by one of the aforementioned brain wave detectors (1) is higher than 50, the cumulative value is 1, and then measured by the aforementioned brain wave detector (1). When the concentration value of brain wave information is higher than 50, it can be accumulated to 2, and so on. This also allows the user to quickly determine the concentration of the group from the multi-person brainwave analysis data.
