此處,腦活動,係採取包含視覺功能、聽覺功能、運動功能、短期記憶、和長期記憶的屬性(標記屬性)。腦活動的屬性,係腦活動具有的固有的性質、特性、特徵等。腦活動的屬性(腦活動屬性),係主要為對應於身體的功能的屬性。視覺功能,係從眼睛取得視覺資訊的功能。聽覺功能,係從耳取得音響資訊的功能。運動功能,係使手、腳等動作的功能。短期記憶,係記憶的對象的提示後數秒至數十秒程度的期間所保持的記憶。長期記憶,係記憶的對象的提示後比保持短期記憶的期間長的期間所保持的記憶。腦活動的屬性的種類,係未限定於此等,在腦活動方面,係可包含更多種類的屬性。 Here, brain activity adopts attributes (marked attributes) including visual function, auditory function, motor function, short-term memory, and long-term memory. The attributes of brain activity are the inherent properties, characteristics, and characteristics of brain activity. The attributes of brain activity (brain activity attributes) are mainly attributes corresponding to the functions of the body. Visual function is the function of obtaining visual information from the eyes. Hearing function is the function of obtaining audio information from the ear. Motor function is the function of making hands, feet and other movements. Short-term memory is the memory that is maintained for a few seconds to tens of seconds after the reminder of the memorized object. Long-term memory refers to the memory maintained for a period longer than the period of maintaining short-term memory after the reminder of the memory object. The types of attributes of brain activity are not limited to these. In terms of brain activity, the system can include more types of attributes.
此外,腦活動的各屬性,係採取具有固有的腦活動波形(基本波形)。亦即,例如,從利用者的眼睛取得視覺資訊時(使用視覺功能時),於腦活動波形,係採取包含視覺功能固有的腦活動波形。其中,腦活動的各屬性的基本波形,並非需要數學上嚴密的獨立性者。透過頭戴裝置10而測定的腦活動波形,係採用腦活動的各屬性的基本波形的和。含於腦活動波形的腦活動的基本波形的大小,係依存於與使用腦活動的各屬性的程度對應的大小。
In addition, the various attributes of brain activity are based on inherent brain activity waveforms (basic waveforms). That is, for example, when visual information is obtained from the user's eyes (when the visual function is used), the brain activity waveform includes the brain activity waveform inherent to the visual function. Among them, the basic waveform of each attribute of brain activity does not require mathematically strict independence. The brain activity waveform measured through the head-mounted
伺服器30,係對於各既定行動,預先設定利

此處,Xa係是腦活動的屬性的1者的視覺功能的固有的腦活動波形(基本波形),Xb係聽覺功能的基本波形,Xc係運動功能的基本波形,Xd係短期記憶的基本波形,Xe係長期記憶的基本波形。此外,Ma1係對於該既定行動(app1)的視覺功能的權重(屬性值),Mb1係對於該既定行動的聽覺功能的權重,Mc1係對於該既定行動的運動功能的權重,Md1係對於該既定行動的短期記憶的權重,Me1係對於該既定行動的長期記憶的權重。與既定行動相關的腦活動的屬性的權重,係顯示針對該屬性所期待的腦活動的大小的量。與既定行動相關的腦活動的屬性的權重,係顯示既定行動的腦活動狀態的傾向。在某既定行動中某腦活動的屬性的權重(屬性值)越大,表示在進行該既定行動時該腦活動的屬性的功能越加活躍地發揮功能。各屬性的權重,係透過支援動畫的製作者(既定行動為以動畫收看的情況)、遊戲的作成者(既定行動為遊戲的運行的情況)等的既定行動的工具、或應用程式等的設計者而預先設定。此等工具、應用程式等,係以利用者終端20
以外的控制機器而提供。設定各屬性的權重者,係依既定行動的特性而設定各屬性的權重。與既定行動相關的腦活動的屬性的權重,係被以權重表T10儲存於伺服器30的記憶體32。
Here, Xa is the unique brain activity waveform (basic waveform) of the visual function of one of the attributes of brain activity, Xb is the basic waveform of auditory function, Xc is the basic waveform of motor function, and Xd is the basic waveform of short-term memory. , Xe is the basic waveform of long-term memory. In addition, Ma1 is the weight (attribute value) of the visual function of the predetermined action (app1), Mb1 is the weight of the auditory function of the predetermined action, Mc1 is the weight of the motor function of the predetermined action, and Md1 is the weight of the predetermined action. The weight of the short-term memory of the action, Me1 is the weight of the long-term memory of the given action. The weight of an attribute of brain activity related to a predetermined action is a quantity that shows the magnitude of brain activity expected for the attribute. The weight of the attribute of the brain activity related to the predetermined action is the tendency to show the brain activity state of the predetermined action. The greater the weight (attribute value) of the attribute of a certain brain activity in a certain predetermined action, the more actively the function of the attribute of the brain activity functions when the predetermined action is performed. The weight of each attribute is based on the design of tools or applications that support the predetermined actions of the creator of the animation (the predetermined action is the case of watching the animation), the creator of the game (the predetermined action is the case of the game running), etc. Which is preset. These tools, applications, etc. are based on the
圖7,係針對權重表之例進行繪示的圖。在圖7的權重表T10,係既定行動的名稱、既定行動的ID、和腦活動的各屬性的權重(屬性值)被賦予對應而儲存。於權重表T10,係針對複數個既定行動,包含ID及腦活動的屬性的權重。例如,在既定行動的名稱「行動A」,係ID被儲存為「001」,視覺功能的權重(屬性值)被儲存為「3」,聽覺功能的權重被儲存為「0」,運動功能的權重被儲存為「1」,短期記憶的權重被儲存為「2」,長期記憶的權重被儲存為「0」。 Fig. 7 is a drawing for an example of a weight table. In the weight table T10 of FIG. 7, the name of the predetermined action, the ID of the predetermined action, and the weight (attribute value) of each attribute of the brain activity are associated and stored. In the weight table T10, it is the weight of attributes for a plurality of predetermined actions, including ID and brain activity. For example, in the name of a given action "action A", the system ID is stored as "001", the weight of visual function (attribute value) is stored as "3", the weight of auditory function is stored as "0", The weight is stored as "1", the short-term memory weight is stored as "2", and the long-term memory weight is stored as "0".
在S103,伺服器30,係從累積於記憶體32的各種的利用者的進行各種的既定行動時的腦活動波形,算出按腦活動的屬性各者的基本波形。腦活動的各屬性的權重,係被按既定行動各者透過權重表T10而賦予。因此,伺服器30,係透過累積於記憶體32的腦活動波形與權重表T10的權重,透過上述的式(1),算出按腦活動的屬性各者的基本波形(Xa,...,Xe)。腦活動的屬性為5種類的情況下,原則上,只要包含5個以上的既定行動的腦活動波形,即可算出基本波形。亦即,可透過將根據複數個既定行動的腦活的屬性的權重的矩陣進行對角化,從而算出按腦活動的屬性各者的基本波形(Xa,...,Xe)。更具
體而言,例如存在與既定行動(app1~app5)相關的腦活動波形(Sapp1~Sapp5)時,使用根據與既定行動(app1~app5)相關的腦活動的屬性的權重(Ma1~Me1,...,Ma5~Me5)的矩陣,按腦活動的屬性各者的基本波形(Xa,...,Xe),係例如以如下的式子表示。

解開此式(2)使得可求出按腦活動的屬性各者的基本波形(Xa,...,Xe)。可透過使用更多的腦活動波形,從而算出更正確的基本波形。伺服器30,係亦可在按既定行動各者將腦活動波形平均化後算出基本波形。伺服器30,係將所算出的按腦活動各者的基本波形(Xa,...,Xe)儲存於記憶體32。此外,計測長度(時間的長度)因腦活動波形而異的情況下,可透過從矩形波的反摺積推定瞬時響應函數,而消除計測長度的差異的影響。
Solving this formula (2) makes it possible to find the basic waveforms (Xa,..., Xe) for each attribute of brain activity. By using more brain activity waveforms, more accurate basic waveforms can be calculated. The
在S104,伺服器30,係針對累積於記憶體32的各種的利用者的進行各種的既定行動時的腦活動波形,算出腦活動值。腦活動值,係根據腦活動波形的振幅寬(最大值與最小值的差)、腦活動波形的變化量積算值、腦活動波形的變化速度、腦活動波形的反復再現性等而算出。腦活動值係顯示腦活動的程度的值,腦活動值越大,
表示腦越活躍地活動。伺服器30,係可按利用者各者、按既定行動各者、按日期時間各者算出腦活動值。伺服器30,係將所算出的腦活動值儲存於記憶體32。再者,伺服器30,係將儲存於記憶體32的腦活動值,透過顯示部35及/或輸出部37的顯示手段等而顯示(輸出)。利用者,係可確認顯示於顯示部35及/或輸出部37的顯示手段等的腦活動值,而辨識既定行動的成果等。各利用者,係例如能以過去的腦活動值為參考,而為了使腦活動活性化實施各行動。

此外,伺服器30,係亦可按利用者的屬性各者算出腦活動值。例如,伺服器30,係在算出20歲以上的男性進行既定行動「行動A」時的腦活動值時,將既定行動「行動A」的腦活動波形抽出,從與該腦活動波形賦予對應的利用者之中,運用個人資訊表T20等,而抽出20歲以上的男性,運用所抽出的利用者的腦活動波形,而算出腦活動值。藉此,可算出特定的條件下的腦活動值、腦活動值等的分布。伺服器30,係將所算出的腦活動值、腦活動值等的分布,儲存於記憶體32。伺服器30,係將儲存於記憶體32的腦活動值、腦活動值的分布,透過顯示部35及/或輸出部37的顯示手段等而顯示。確認所顯示的腦活動值等的利用者,係例如將進行特定的既定行動時的具有特定的疾病的利用者的腦活動值、和不具有該疾病的利用者的腦活動值進行比較而存在統計上顯著性差異時,可使用進行該既定行動時的腦活動波形
(腦活動值),而利用於檢測出具有該疾病者。
In addition, the
再者,伺服器30,係亦可根據式(1)而針對特定的利用者的特定的既定行動,從按腦活動的屬性各者的基本波形、腦活動波形,算出各屬性的權重。此時,例如,以各屬性的基本波形與乘上權重者的和成為腦活動波形的方式調節各屬性的權重,從而算出各屬性的權重。伺服器30,係將所算出的各屬性的權重儲存於記憶體32。伺服器30,係將儲存於記憶體32的各屬性的權重,透過顯示部35及/或輸出部37的顯示手段等而顯示。藉此,將按設定於既定行動的腦活動的屬性各者的權重、和此處所算出的權重進行比較,使得可確認那個腦活動的屬性的功能更活躍。亦可使此處所算出的各屬性的權重為各屬性的腦活動值。

此外,在具有特定的疾病的利用者(群組A)的特定的腦活動的屬性的腦活動值、和不具有該特定的疾病的利用者(群組B)的特定的腦活動的屬性的腦活動值方面產生統計上顯著性差異時,針對該特定的疾病利用不明的利用者的該特定的腦活動的屬性的腦活動值,而判定接近群組A的腦活動值或接近群組B的腦活動值,使得可判定是否可能具有該疾病。此外,探索產生顯著性差異的腦活動的屬性,使得可導出供於發現具有特定的疾病的利用者用的腦活動的屬性。再者,設計為使所導出的腦活動的屬性的權重大的既定行動進行,使得容易透過該既定行動而發現具有特定的疾病的利用者。 In addition, the brain activity value of the specific brain activity attribute of the user (group A) with a specific disease, and the specific brain activity attribute of the user (group B) who does not have the specific disease When there is a statistically significant difference in the brain activity value, the brain activity value of the specific brain activity attribute of the unknown user for the specific disease is used to determine the brain activity value close to group A or close to group B The value of brain activity, making it possible to determine whether the disease is possible. In addition, exploring the attributes of brain activity that produce significant differences makes it possible to derive the attributes of brain activity for users who have discovered a specific disease. Furthermore, it is designed to perform a predetermined action with a significant weight of the attribute of the derived brain activity, so that it is easy to find a user with a specific disease through the predetermined action.
此外,伺服器30,係亦可於顯示部35及/或輸出部37的顯示手段等顯示複數個利用者進行相同的既定行動時的他人的腦活動值與自己的腦活動值的比較。藉此利用者,係可掌握例如整體上的本身的順位等。再者,將相同的利用者進行相同的既定行動時的自己的過去的腦活動值、和自己的目前的腦活動值進行比較,使得利用者係可確認已與過去的自己進行比較的目前的腦活動的狀態。

In addition, when the weight of the attribute of the new brain activity is expressed as a function of the weight of each attribute of the existing brain activity, the function is used to determine the weight of the attribute of the new brain activity.
