　次に、図９Ａ、図９Ｂを参照して、本実施形態の端末装置３００の動作について説明する。図９Ａは、端末装置の動作を説明する第一のフローチャートであり、図９Ｂは、端末装置の動作を説明する第二のフローチャートである。 Next, the operation of the terminal device 300 of the present embodiment will be described with reference to FIGS. 9A and 9B. FIG. 9A is a first flowchart for explaining the operation of the terminal device, and FIG. 9B is a second flowchart for explaining the operation of the terminal device.
　本実施形態の端末装置３００は、端末装置３００のユーザがコンテンツの体験（視聴）を行う際に、コンテンツＩＤを取得する（ステップＳ９０１）。 The terminal device 300 of the present embodiment acquires a content ID when the user of the terminal device 300 experiences (views) the content (step S901).
　具体的には、例えば、端末装置３００は、ユーザによって、コンテンツＩＤが埋め込まれた二次元コードが翳されると、この二次元コードを読み取って、コンテンツＩＤを取得しても良い。また、端末装置３００は、例えば、ユーザによって、コンテンツの体験を予約するための予約情報が予め入力されていた場合等には、この情報からコンテンツＩＤを取得しても良い。 Specifically, for example, when the user holds a two-dimensional code in which the content ID is embedded, the terminal device 300 may read the two-dimensional code to acquire the content ID. Further, the terminal device 300 may acquire the content ID from, for example, when the reservation information for reserving the experience of the content is input in advance by the user.
　続いて、端末装置３００は、情報提供部３１０により、センサ２００からセンサ情報を受信しているか否かを判定する（ステップＳ９０２）。つまり、ここでは、センサ２００がユーザに貼り付けられて、センサ２００によるセンサ情報の取得が開始されたか否かを判定している。 Subsequently, the terminal device 300 determines whether or not the sensor information is received from the sensor 200 by the information providing unit 310 (step S902). That is, here, it is determined whether or not the sensor 200 is attached to the user and the acquisition of the sensor information by the sensor 200 is started.
　ステップＳ９０２において、センサ情報を受信していない場合、端末装置３００は、図９Ｂに示す処理Ａへ進む。 If the sensor information is not received in step S902, the terminal device 300 proceeds to process A shown in FIG. 9B.
　ステップＳ９０２において、センサ情報を受信している場合、端末装置３００は、情報提供部３１０のセンサ情報取得部３１１により、センサ情報の取得を開始する（ステップ　Ｓ９０３）。 When the sensor information is received in step S902, the terminal device 300 starts acquiring the sensor information by the sensor information acquisition unit 311 of the information providing unit 310 (step S903).
　以下に説明するステップＳ９０４からステップＳ９１２の処理は、コンテンツ評価データベース４２０に格納される生体情報４２１を取得する処理である。 The processes from steps S904 to S912 described below are processes for acquiring biometric information 421 stored in the content evaluation database 420.
　続いて、情報提供部３１０は、生体情報取得部３１２により、取得したセンサ情報に含まれる心電波形データから、ＲＲＩ（Ｒ－Ｒ　Ｉｎｔｅｒｖａｌ）データを取得する（ステップＳ９０４）。ＲＲＩデータとは、心拍の変動時系列データである。 Subsequently, the information providing unit 310 acquires RRI (RR Interval) data from the electrocardiographic waveform data included in the acquired sensor information by the biological information acquisition unit 312 (step S904). The RRI data is time series data of heartbeat fluctuations.
　続いて、情報提供部３１０は、ＲＲＩデータに基づき、心拍数を取得する（ステップＳ９０５）。次に、情報提供部３１０は、安静時心拍数と、取得したＲＲＩデータから得られる最高心拍数と、を取得する（ステップＳ９０６）。 Subsequently, the information providing unit 310 acquires the heart rate based on the RRI data (step S905). Next, the information providing unit 310 acquires the resting heart rate and the maximum heart rate obtained from the acquired RRI data (step S906).
　最高心拍数とは、取得したＲＲＩデータから得られる心拍数における最高心拍数である。安静時心拍数とは、例えば、センサ情報の取得を開始したときの心拍数であっても良い。安静時心拍数とは、端末装置３００のユーザに対してコンテンツの提供が開始される前に取得された心拍数であれば良い。 The maximum heart rate is the maximum heart rate in the heart rate obtained from the acquired RRI data. The resting heart rate may be, for example, the heart rate at the start of acquisition of sensor information. The resting heart rate may be any heart rate acquired before the content is provided to the user of the terminal device 300.
　続いて、情報提供部３１０は、生体情報取得部３１２の興奮度算出部３２１により、端末装置３００のユーザの興奮度を算出する（ステップＳ９０７）。 Subsequently, the information providing unit 310 calculates the excitement degree of the user of the terminal device 300 by the excitement degree calculation unit 321 of the biological information acquisition unit 312 (step S907).
　以下に、本実施形態の興奮度について説明する。本実施形態の興奮度とは、端末装置３００のユーザの心電波形データを用いて取得される値であり、ユーザの感情の高ぶりの度合いを示す。言い換えれば、興奮度は、ユーザの気分の高揚の度合いを示す。 The degree of excitement of this embodiment will be described below. The degree of excitement of the present embodiment is a value acquired by using the electrocardiographic waveform data of the user of the terminal device 300, and indicates the degree of high emotion of the user. In other words, the degree of excitement indicates the degree of uplifting of the user's mood.
　本実施形態の興奮度算出部３２１は、以下の式（１）によって、興奮度を算出する。 The excitement degree calculation unit 321 of the present embodiment calculates the excitement degree by the following formula (1).
　興奮度＝１００×（最高心拍数－安静時心拍数）／（最大心拍数－安静時心拍数）　（１）
　最大心拍数は、以下の式（２）によって得られる。 Excitement = 100 x (maximum heart rate-resting heart rate) / (maximum heart rate-resting heart rate) (1)
The maximum heart rate is obtained by the following equation (2).
　最大心拍数＝２０６．９－０．６７×年齢　（２）
　尚、本実施形態では、端末装置３００のユーザＩＤや年齢等といった情報は、予め端末装置３００に登録されているものとした。 Maximum heart rate = 206.9-0.67 x age (2)
In this embodiment, it is assumed that information such as the user ID and age of the terminal device 300 is registered in the terminal device 300 in advance.
　続いて、興奮度算出部３２１は、算出した興奮度から、平均興奮度と、興奮回数とを算出する（ステップＳ９０８）。 Subsequently, the excitement degree calculation unit 321 calculates the average excitement degree and the number of excitements from the calculated excitement degree (step S908).
　平均興奮度は、これまで取得した興奮度の平均値であり、興奮回数とは、興奮度が予め設定された興奮度閾値以上となった回数を示す。 The average degree of excitement is the average value of the degree of excitement acquired so far, and the number of times of excitement indicates the number of times the degree of excitement exceeds a preset degree of excitement threshold.
　続いて、情報提供部３１０は、熱中度算出部３２２により、ＬＦ（Ｌｏｗ－Ｆｒｅｑｕｅｎｃｙ）／ＨＦ（Ｈｉｇｈ－Ｆｒｅｑｕｅｎｃｙ）比を算出する（ステップＳ９０９）。 Subsequently, the information providing unit 310 calculates the LF (Low-Frequency) / HF (High-Frequency) ratio by the heat medium degree calculation unit 322 (step S909).
　ＬＦ／ＨＦ比は、交感神経の活性度を示す指標（ストレス指標）であり、交感神経と副交感神経のバランスを示す。 The LF / HF ratio is an index (stress index) indicating the activity of the sympathetic nerve, and indicates the balance between the sympathetic nerve and the parasympathetic nerve.
　以下に、ＬＦ／ＨＦ比の算出方法について説明する。 The method of calculating the LF / HF ratio will be described below.
　まず、熱中度算出部３２２は、ＲＲＩデータに対して高速フーリエ変換処理を行い、ＲＲＩデータから、パワースペクトル密度を計算する。次に、熱中度算出部３２２は、ＬＦ成分とＨＦ成分を抽出し、各成分の大きさを求める。 First, the heat medium degree calculation unit 322 performs a fast Fourier transform process on the RRI data, and calculates the power spectral density from the RRI data. Next, the heat middle degree calculation unit 322 extracts the LF component and the HF component, and obtains the size of each component.
　ＬＦ成分とは、血圧変動に対応する０．０５Ｈｚ～０．１５Ｈｚまでの低周波数成分である。ＨＦ成分とは、呼吸変動に対応する０．１５Ｈｚ～０．４０Ｈｚまでの高周波成分である。 The LF component is a low frequency component from 0.05 Hz to 0.15 Hz corresponding to blood pressure fluctuation. The HF component is a high frequency component from 0.15 Hz to 0.40 Hz corresponding to respiratory fluctuations.
　熱中度算出部３２２は、ＲＲＩデータから取得したパワースペクトルのＬＦ成分の領域の強度を合計し、ＬＦ成分の大きさとする。また、熱中度算出部３２２は、ＲＲＩデータから取得したパワースペクトルのＨＦ成分の領域の強度を合計し、ＨＦ成分の大きさとする。 The thermal degree calculation unit 322 totals the intensities of the LF component region of the power spectrum acquired from the RRI data, and determines the magnitude of the LF component. Further, the thermal degree calculation unit 322 totals the intensities of the HF component region of the power spectrum acquired from the RRI data, and sets the magnitude of the HF component.
　そして、熱中度算出部３２２は、ＬＦ成分の大きさと、ＨＦ成分の大きさとの比率をＬＦ／ＨＦ比とする。 Then, the heat medium degree calculation unit 322 sets the ratio of the size of the LF component and the size of the HF component as the LF / HF ratio.
　続いて、熱中度算出部３２２は、ＬＦ／ＨＦ比に基づき、ストレス値を取得する（ステップＳ９１０）。 Subsequently, the heat medium degree calculation unit 322 acquires the stress value based on the LF / HF ratio (step S910).
　本実施形態の熱中度算出部３２２は、ＬＦ／ＨＦ比に基づき、ストレス値を３つの段階の何れかで示す。 The heat middle degree calculation unit 322 of the present embodiment indicates the stress value in any of three stages based on the LF / HF ratio.
　具体的には、熱中度算出部３２２は、ＬＦ／ＨＦ比が第一の閾値未満である場合には、ストレス値を「小」とし、ＬＦ／ＨＦ比が第二の閾値より大きい場合には、ストレス値を「大」とし、ＬＦ／ＨＦ比が第一の閾値以上第二の閾値未満である場合には、ストレス値を「中」とする。 Specifically, the heat middle degree calculation unit 322 sets the stress value to "small" when the LF / HF ratio is less than the first threshold value, and sets the stress value to "small" when the LF / HF ratio is larger than the second threshold value. , The stress value is set to "large", and when the LF / HF ratio is equal to or more than the first threshold value and less than the second threshold value, the stress value is set to "medium".
　ＬＦ／ＨＦ比が第一の閾値未満である場合とは、副交感神経が活発な状態であり、リラックスしている状態を示す。また、ＬＦ／ＨＦ比が第二の閾値より大きい場合とは、交感神経が活発に状態であり、緊張している状態である。 When the LF / HF ratio is less than the first threshold value, it means that the parasympathetic nerve is in an active state and is in a relaxed state. Further, when the LF / HF ratio is larger than the second threshold value, the sympathetic nerve is in an active state and is in a tense state.
　本実施形態では、リラックスしている状態をストレスが小さい状態とし、緊張している状態をストレスが大きい状態としている。 In the present embodiment, the relaxed state is defined as a state of low stress, and the tense state is defined as a state of high stress.
　尚、ストレス値を判定するための第一の閾値及び第二の閾値は、任意に設定することができる。この２つの閾値は、例えば、端末装置３００のユーザの年齢や性別、健康状態等に応じて異なる値が設定されても良い。 The first threshold value and the second threshold value for determining the stress value can be arbitrarily set. For example, different values may be set for these two threshold values according to the age, sex, health condition, and the like of the user of the terminal device 300.
　また、ストレス値は、３つの段階で示されなくても良く、ストレス値の表現の仕方は任意であって良い。 Also, the stress value does not have to be shown in three stages, and the way of expressing the stress value may be arbitrary.
　続いて、情報提供部３１０は、加速度・位置取得部３１３により、端末装置３００の位置を示す位置情報と、加速度とを取得する（ステップＳ９１１）。 Subsequently, the information providing unit 310 acquires the position information indicating the position of the terminal device 300 and the acceleration by the acceleration / position acquisition unit 313 (step S911).
　続いて、情報提供部３１０は、熱中度算出部３２２により、ステップＳ９１０で取得したストレス値と、ステップＳ９１１で取得した加速度とに応じて、熱中度を取得する（ステップＳ９１２）。 Subsequently, the information providing unit 310 acquires the heat degree by the heat medium degree calculation unit 322 according to the stress value acquired in step S910 and the acceleration acquired in step S911 (step S912).
　以下に、本実施形態の熱中度について説明する。本実施形態の熱中度とは、ユーザの心電波形データを用いて取得される値であり、ユーザがコンテンツに熱中している度合いを示す。熱中している度合いとは、言い換えれば、ユーザによる、コンテンツを視聴・体験することに対する集中の度合いである。 The enthusiastic degree of this embodiment will be described below. The enthusiastic degree of the present embodiment is a value acquired by using the electrocardiographic waveform data of the user, and indicates the degree to which the user is enthusiastic about the content. The degree of enthusiasm is, in other words, the degree of concentration by the user on viewing / experiencing the content.
　本実施形態では、熱中度は、ストレス値と、加速度に応じて判定されるユーザの状態の有無とに応じて、３段階の値で示すものとした。 In the present embodiment, the degree of heat is indicated by a value in three stages according to the stress value and the presence or absence of the state of the user determined according to the acceleration.
　ここで、加速度に応じたユーザの状態の判定について説明する。本実施形態の熱中度算出部３２２は、ユーザの状態を判定する際に参照する第一の加速度閾値と、第二の加速度閾値とを保持している。 Here, the determination of the user's state according to the acceleration will be described. The heat middle degree calculation unit 322 of the present embodiment holds a first acceleration threshold value and a second acceleration threshold value to be referred to when determining the state of the user.
　本実施形態の熱中度算出部３２２は、加速度が第一の加速度閾値未満である場合には、ユーザの状態を静止している状態と判定し、加速度が第二の加速度閾値より大きい場合には、ユーザの状態を躍動している状態と判定する。また、熱中度算出部３２２は、加速度が、第一の加速度閾値以上であり、第二の加速度閾値未満である場合には、ユーザの状態を通常の動作をしている状態と判定する。 The thermal degree calculation unit 322 of the present embodiment determines that the user's state is stationary when the acceleration is less than the first acceleration threshold value, and when the acceleration is larger than the second acceleration threshold value, the user's state is determined to be stationary. , Determines the user's state as dynamic. Further, when the acceleration is equal to or more than the first acceleration threshold value and less than the second acceleration threshold value, the heat middle degree calculation unit 322 determines that the user's state is a state of performing a normal operation.
　本実施形態の熱中度算出部３２２は、上述した加速度に基づくユーザの状態の判定の結果、ユーザの状態が躍動した状態であり、且つ、ストレス値が「小」であった場合、このユーザの熱中度を「大」とする。また、熱中度算出部３２２は、例えば、ユーザの状態が通常の動作をしている状態で、且つ、ストレス値が「大」である場合には、熱中度を「小」としても良い。 The thermal degree calculation unit 322 of the present embodiment determines the state of the user based on the above-mentioned acceleration, and when the state of the user is in a dynamic state and the stress value is "small", the state of the user is determined. The degree of enthusiasm is "large". Further, the heat middle degree calculation unit 322 may set the heat middle degree to "small", for example, when the user's state is in a normal operation state and the stress value is "large".
　このように、本実施形態では、心電波形データを用いて取得されたストレス値と、ユーザの状態との組み合わせに応じて、コンテンツに対する熱中度を取得する。 As described above, in the present embodiment, the degree of enthusiasm for the content is acquired according to the combination of the stress value acquired using the electrocardiographic waveform data and the state of the user.
　尚、本実施形態では図示していないが、ストレス値と、ユーザの状態との組み合わせと、各組み合わせに対応する熱中度とが対応付けられた対応付け情報が、端末装置３００に保持されていても良い。また、この対応付け情報は、サーバ装置４００に保持されていても良い。 Although not shown in the present embodiment, the terminal device 300 holds associative information in which the combination of the stress value and the user's state and the enthusiastic degree corresponding to each combination are associated with each other. Is also good. Further, this association information may be held in the server device 400.
　また、ストレス値とユーザの状態との組み合わせのパターンや、組み合わせと対応する熱中度は、コンテンツの種類に応じて異なっても良い。 In addition, the pattern of the combination of the stress value and the user's condition and the degree of enthusiasm corresponding to the combination may differ depending on the type of content.
　例えば、コンテンツの種類が、スタジアムでのスポーツ観戦であった場合には、ユーザの状態が躍動した状態であり、且つ、ストレス値が「小」であった場合、このユーザの熱中度を「大」となるが、コンテンツの種類が、例えば、プラネタリウム等のような施設で提供されるものである場合には、ユーザの状態が静止した状態であり、且つ、ストレス値が「小」である場合に、このユーザの熱中度を「大」としても良い。これらの組み合わせは、コンテンツの種類に応じて、任意に設定されて良い。 For example, when the type of content is watching sports at a stadium, the user's state is in a dynamic state, and when the stress value is "small", the user's enthusiasm is set to "high". However, when the type of content is provided in a facility such as a planetarium, the user's state is stationary and the stress value is "small". In addition, the enthusiastic level of this user may be set to "large". These combinations may be arbitrarily set according to the type of content.
　情報提供部３１０は、熱中度算出部３２２により熱中度が取得されると、ステップＳ９０２へ戻る。 The information providing unit 310 returns to step S902 when the heat medium degree is acquired by the heat medium degree calculation unit 322.
　また、情報提供部３１０は、図９ＡのステップＳ９０２において、センサ情報を受信しない場合、図９Ｂに示す処理Ａへ進み、生体情報を取得したか否かを判定する（ステップＳ９１３）。ステップＳ９１３において、生体情報を取得していない場合、情報提供部３１０は、処理を終了する。 If the sensor information is not received in step S902 of FIG. 9A, the information providing unit 310 proceeds to process A shown in FIG. 9B and determines whether or not the biometric information has been acquired (step S913). If the biometric information has not been acquired in step S913, the information providing unit 310 ends the process.
　ステップＳ９１３において、生体情報を取得していた場合、情報提供部３１０は、生体情報を取得していた期間に、端末装置３００が購入履歴情報を取得したか否かを判定する（ステップＳ９１４）。 If the biometric information has been acquired in step S913, the information providing unit 310 determines whether or not the terminal device 300 has acquired the purchase history information during the period in which the biometric information was acquired (step S914).
　ステップＳ９１４において、購入履歴情報を取得している場合、情報提供部３１０は、取得した生体情報、加速度・位置情報、購入履歴情報を、端末装置３００と紐付けられたユーザＩＤ及び、ステップＳ９０１で取得したコンテンツＩＤと共にサーバ装置４００へ送信し（ステップＳ９１５）、処理を終了する。 When the purchase history information is acquired in step S914, the information providing unit 310 transfers the acquired biological information, acceleration / position information, and purchase history information to the user ID associated with the terminal device 300 and step S901. It is transmitted to the server device 400 together with the acquired content ID (step S915), and the process ends.
　ステップＳ９１４において、購入履歴情報を取得していない場合、情報提供部３１０は、取得した生体情報、加速度・位置情報を、端末装置３００と紐付けられたユーザＩＤと共にサーバ装置４００へ送信し（ステップＳ９１６）、処理を終了する。 If the purchase history information has not been acquired in step S914, the information providing unit 310 transmits the acquired biometric information and acceleration / position information to the server device 400 together with the user ID associated with the terminal device 300 (step S914). S916), the process is terminated.
　尚、図９Ａ、図９Ｂの例では、情報提供部３１０がセンサ情報の受信が終了してから、生体情報等をサーバ装置４００へ送信するものとしたが、これに限定されない。情報提供部３１０は、センサ情報を受信し、ステップＳ９０４からステップＳ９１３の処理を実行する度に、処理の結果として取得される生体情報をサーバ装置４００へ送信しても良い。 In the examples of FIGS. 9A and 9B, the biometric information and the like are transmitted to the server device 400 after the information providing unit 310 finishes receiving the sensor information, but the present invention is not limited to this.
