Description

アトラクション装置の制御方法およびアトラクションシステムControl method of attraction apparatus and attraction system
 本開示は、アトラクション装置を制御するための技術に関する。 The present disclosure relates to techniques for controlling the attraction device.
 遊園地、テーマパーク、アミューズメントパークなどのアミューズメント施設には、様々なアトラクション装置が設置されている。例えば、ジェットコースター(roller coaster)およびダークライドと呼ばれる乗り物遊具が設置されている。ジェットコースターは、地上高くに設置された急勾配の線路を高速で走行したり急旋回したりすることにより、ユーザにスリルを与える。ダークライドは、主に屋内に設置され、映像または展示物に合わせてライド装置の動きを変化させることにより、ユーザにスリルまたは驚きを与える。近年では、ダークライドとヘッドマウントディスプレイ(HMD)とを組み合わせた新しいタイプのアトラクションも導入されている。HMDに提示する映像とライド装置の動きとを同調させることで、ユーザの没入感を飛躍的に高めることに成功している。 Amusement parks, theme parks, to the amusement facilities such as amusement park, has been installed a variety of attractions equipment. For example, vehicle playground equipment called a roller coaster (roller coaster) and a dark ride is installed. The roller coaster thrills the user by traveling at high speed or making a sharp turn on a steep track installed high above the ground. The dark ride is installed mainly indoors and gives the user a thrill or surprise by changing the movement of the ride device in accordance with the image or the exhibit. In recent years, it has also been introduced a new type of attraction that combines the dark ride and a head-mounted display (HMD). By synchronizing the image presented to the HMD with the movement of the ride device, it has succeeded in dramatically enhancing the user's sense of immersion.
 他方、映画などの映像、またはゲームを提供するシステムにおいて、ユーザの生体情報に基づいて映像またはゲームの難易度を変更する技術が知られている。例えば、特許文献1および2は、そのような技術の例を開示している。 On the other hand, in a system for providing video or game, such as a movie, a technique for changing the difficulty level of the video or game based on biometric information of the user it is known. For example, Patent Documents 1 and 2 disclose examples of such techniques.

 (第1の実施形態)
 図1は、本開示の例示的な実施形態におけるアトラクションシステム10の概略的な構成を示す図である。このアトラクションシステム10は、検出装置100と、アトラクション装置200と、制御装置500とを備えている。制御装置500は、検出装置100およびアトラクション装置200に接続され、これらを制御する。
First Embodiment
FIG. 1 is a diagram showing a schematic configuration of an attraction system 10 in an exemplary embodiment of the present disclosure. The attraction system 10 includes a detection device 100, an attraction device 200, and a control device 500. Controller 500 is connected to the detection device 100 and the attraction device 200, and controls these.
 本実施形態におけるアトラクション装置200は、アミューズメント施設に設置され、少なくとも一人のユーザ600に少なくとも一つの刺激を提供する装置であり、家庭用ゲーム機ではない。すなわち、アトラクション装置200は、例えば特許文献2に開示されているゲーム機のように、一般家庭で使用され、ユーザがコントローラなどを操作することによってゲームが進行する装置ではない。しかし、以下に詳しく説明する制御方法は、家庭用ゲーム機などの、アミューズメント施設以外の場所で使用されるエンターテインメント用途の機器にも同様に適用することができる。 The attraction apparatus 200 in the present embodiment is an apparatus installed at an amusement facility and providing at least one stimulus to at least one user 600, and is not a home-use game machine. That is, the attraction device 200 is not a device that is used in a general home, such as a game machine disclosed in Patent Document 2, for example, and a game is advanced by the user operating a controller or the like. However, the control method described below in more detail, such as a home-use game machine, it can also be applied in the same manner to the equipment of entertainment applications to be used in a location other than the amusement facility.
 検出装置100は、ユーザ600の心理状態に応じて変化する生体情報を検出する。生体情報は、例えば、ユーザ600の被検部における血流の状態を示す情報である血流情報であり得る。被検部は、例えば前頭部であるが、他の部位であってもよい。検出装置100によって検出され得る血流情報は、例えば、脳血流または皮膚血流の情報であり得る。脳血流情報または前頭部の皮膚血流情報は、例えば、ユーザ600の前額部の少なくとも一部を近赤外線などの光で照射し、その反射光を検出することによって取得できる。生体情報は、血流情報に限定されず、ユーザ600の心理状態を反映したものであれば、何でもよい。例えば、ユーザ600の皮膚の温度もしくは電気抵抗、または心拍数などの情報も、生体情報として利用され得る。 The detection device 100 detects biological information that changes according to the mental state of the user 600. Biometric information may be, for example, a blood flow information is information indicating the state of blood flow in the object part of the user 600. The test part is, for example, the forehead, but may be another part. Blood flow information that can be detected by the detection device 100 may be, for example, information of cerebral blood flow or skin blood flow. Skin blood flow information of cerebral blood flow information or forehead, for example, at least part of the forehead of the user 600 is irradiated with light such as near infrared, it can be obtained by detecting the reflected light. The biological information is not limited to blood flow information, and may be anything as long as it reflects the mental state of the user 600. For example, temperature or electrical resistance of the skin of the user 600, or information such as heart rate, may be utilized as the biometric information.
 制御装置500は、検出装置100から生体情報を取得し、その情報に基づいて、アトラクション装置200の動作を制御する。制御装置500は、取得した生体情報から、ユーザ600の心理状態を推定することができる。例えば、生体情報がユーザ600の脳における血液中の酸素化ヘモグロビンの濃度に関する情報を含む場合、酸素化ヘモグロビンの濃度から、そのユーザ600が恐怖を感じているか否かを推定することができる。制御装置500は、脳血流情報などの生体情報に基づき、ユーザ600があまり恐怖を感じていないと判断した場合には、ユーザ600に与えられる刺激をより強くして、より恐怖を感じさせるようにすることができる。 The control device 500 acquires biological information from the detection device 100, and controls the operation of the attraction device 200 based on the information. The control device 500 can estimate the mental state of the user 600 from the acquired biological information. For example, when the biological information includes information on the concentration of oxygenated hemoglobin in the blood of the user's 600 brain, it can be estimated from the concentration of oxygenated hemoglobin whether the user 600 feels fear. If the control device 500 determines that the user 600 does not feel much fear based on biological information such as cerebral blood flow information, the control given to the user 600 can be made stronger to make the user feel more fear. Can be
 このような制御を実現するために、制御装置500は、例えば、アトラクション装置200がユーザ600に刺激を与える前後でユーザ600の血流情報をそれぞれ取得し、それらの比較に基づいて、ユーザ600の心理状態を推定してもよい。例えば、ユーザ600の脳血流情報から得られる酸素化ヘモグロビンの濃度が、刺激の前後で閾値よりも大きく変化した場合には、その刺激によってユーザ600が恐怖を感じていると推定することができる。 In order to realize such control, the control device 500 acquires blood flow information of the user 600 before and after, for example, the attraction device 200 stimulates the user 600, and based on their comparison, The mental state may be estimated. For example, when the concentration of oxygenated hemoglobin obtained from the cerebral blood flow information of the user 600 changes by more than a threshold before and after stimulation, it can be estimated that the user 600 feels fear by the stimulation. .
 刺激に対する生体情報の変化には個人差があり、性別によっても異なる傾向がある。例えば、非特許文献3によれば、男性よりも女性の方が、刺激に対する酸素化ヘモグロビンの変化量が一般に大きいことがわかっている。このため、ユーザ600の性別に応じて、心理状態の判定に使用する閾値を変更するなどの調整を行ってもよい。 Changes in biological information in response to stimulation vary among individuals and tend to differ depending on gender. For example, according to Non-Patent Document 3, it is known that the change amount of oxygenated hemoglobin to the stimulus is generally larger in women than in men. For this reason, according to the sex of the user 600, you may perform adjustment of changing the threshold value used for determination of a mental state.
 刺激に対する生体情報の変化には年齢層によっても異なる傾向がある。例えば、前頭前野領域の脳血流は、幼児、成人、老人の3区分において、異なる領域、異なる強度で変化することが知られている。このため、ユーザ600の年齢層に応じて、心理状態の判定に使用する閾値または検出部位を変更するなどの調整を行ってもよい。 The change of the biological information to the stimulation tend to differ depending on age. For example, it is known that cerebral blood flow in the prefrontal region changes in different regions and with different intensities in three segments of infants, adults and old people. Therefore, depending on the age of the user 600 may perform an adjustment such as changing the threshold or detection site used to determine the psychological state.
 このように、本実施形態における制御回路500は、ユーザの性別または年齢層などの、ユーザの属性を示す属性情報に基づき、ユーザの血流情報の変化量の閾値および/または検出部位を変更する。制御回路は、以下の動作を実行する。(1)検出装置に、ユーザの第1の血流情報を取得させる。(2)アトラクション装置に、ユーザに対して第1の刺激を提供させる。(3)第1の刺激が提供された後、検出装置に、ユーザの第2の血流情報を取得させる。(4)第1の血流情報と前記第2の血流情報とに基づいて、血流情報の第1の変化量を計算する。(5)第1の変化量と閾値との比較結果に基づいて、アトラクション装置の動作を制御する。 As described above, the control circuit 500 in the present embodiment changes the threshold value and / or the detection site of the change amount of the blood flow information of the user based on the attribute information indicating the attribute of the user, such as the gender or age group of the user. . The control circuit performs the following operations. (1) The detection device is made to acquire the first blood flow information of the user. (2) The attraction apparatus provides the user with a first stimulus. (3) After the first stimulus is provided, cause the detection device to acquire the second blood flow information of the user. (4) A first change amount of blood flow information is calculated based on the first blood flow information and the second blood flow information. (5) The operation of the attraction apparatus is controlled based on the comparison result of the first change amount and the threshold value.
 このようなアトラクション装置の制御方法によれば、アトラクション装置の動作中に各ユーザが感じた恐怖などの感情に基づき、各ユーザに提供される刺激を適切に制御することができる。例えば、各ユーザに提供される映像の内容、音量、ライド装置の加速度、風量、または匂いなどの刺激の大きさを、ユーザごとに制御することができる。これにより、各ユーザの満足感を高めることができる。 According to such a control method of the attraction apparatus, it is possible to appropriately control the stimulus provided to each user based on the emotion such as the fear felt by each user during the operation of the attraction apparatus. For example, it is possible to control, for each user, the size of the stimulus such as the content of the video provided to each user, the volume, the acceleration of the ride device, the air volume, or the odor. This can enhance the satisfaction of each user.
 図1では、検出装置100、アトラクション装置200、および制御装置500の各々は、1つのブロックとして表現されている。しかし、これらが外観上独立した装置として構成されている必要はない。例えば、制御装置500は、アトラクション装置200または検出装置100に組み込まれていてもよい。あるいは、検出装置100、アトラクション装置200、および制御装置500の全てが、統合された一つの装置に含まれていてもよい。制御装置500と、検出装置100およびアトラクション装置200との接続は、有線接続でも無線接続でもよい。制御装置500は、例えばインターネットなどの遠隔ネットワークを介して検出装置100およびアトラクション装置200に接続されていてもよい。言い換えれば、制御装置500は、クラウド上に配置されたサーバコンピュータによって実現されていてもよい。 In FIG. 1, each of the detection device 100, the attraction device 200, and the control device 500 is represented as one block. However, they do not have to be configured as separate devices in appearance. For example, the controller 500 may be incorporated in the attraction device 200 or the detection device 100. Alternatively, all of the detection device 100, the attraction device 200, and the control device 500 may be included in one integrated device. A control unit 500, connected to the detection device 100 and the attraction device 200 may be a wireless connection and a wired connection. The control device 500 may be connected to the detection device 100 and the attraction device 200 via a remote network such as the Internet, for example. In other words, the control device 500 may be realized by a server computer disposed on a cloud.
 (原理)
 次に、図2を参照しながら、検出装置100による生体情報の計測の原理を説明する。
(principle)
Next, referring to FIG. 2, illustrating the principle of measurement of the biological information by the detecting device 100.
 図2は、検出装置100の構成例を模式的に示す図である。図2には、ユーザの被検部40も示されている。この例における被検部40は、ユーザの額部である。 FIG. 2 is a view schematically showing a configuration example of the detection device 100. As shown in FIG. FIG 2 also shows the test unit 40 of the user. Object part 40 in this example is the forehead of the user.
 検出装置100は、光源102と、光検出器104と、制御回路106と、信号処理回路108とを備えている。光源102は、ユーザの被検部40に向けて光を出射する。光検出器104は、光源102から出射され被検部40で反射された光を検出する。制御回路106は、光源102および光検出器104に接続され、これらの動作を制御する。信号処理回路108は、光検出器104によって検出された光の信号に基づいて、ユーザの脳血流情報を生成して出力する。 Detection device 100 includes a light source 102, a photodetector 104, a control circuit 106, and a signal processing circuit 108. The light source 102 emits light toward the subject 40 of the user. The light detector 104 detects light emitted from the light source 102 and reflected by the subject 40. The control circuit 106 is connected to the light source 102 and the light detector 104 to control their operation. The signal processing circuit 108 generates and outputs cerebral blood flow information of the user based on the light signal detected by the light detector 104.
 この例における検出装置100は、近赤外分光(Near Infrared Spectroscopy:NIRS)による生体計測によってユーザの血流情報を取得する。この生体計測法では、光源102は、近赤外光を人体の額部に照射する。照射された光の一部は、大脳皮質である灰白質56などの脳内組織で乱反射して頭部の外部に出て、検出装置100の方向に戻る。光検出器104は、その戻ってきた光を受け、受光量に応じた電気信号を出力する。信号処理回路108は、当該電気信号に基づいて、受光量の変化を検知し、脳または頭皮における血流の状態を示す血流情報を生成する。 The detection apparatus 100 in this example acquires blood flow information of the user by living body measurement using near infrared spectroscopy (NIRS). In this living body measurement method, the light source 102 emits near infrared light to the forehead of a human body. Some of the irradiated light is diffusely reflected by the brain tissues, such as the gray matter 56 is the cerebral cortex out to the outside of the head, back towards the detector 100. The photodetector 104 receives the returned light and outputs an electrical signal according to the amount of light received. The signal processing circuit 108, based on the electrical signal, detects a change in received light amount, and generates a blood flow information indicating the state of blood flow in the brain or the scalp.
 光源102から出射される光は、近赤外光に限らず、近赤外光に波長が近い可視光でもよい。使用される光の波長は、脳血流および皮膚血流の少なくとも一方の情報が得られる波長であればよく、例えば、600nmから1400nm程度の波長が使用される。 The light emitted from the light source 102 is not limited to near infrared light, and may be visible light whose wavelength is close to near infrared light. The wavelength of light to be used may be a wavelength at which information on at least one of cerebral blood flow and skin blood flow can be obtained, and for example, a wavelength of about 600 nm to 1400 nm is used.
 図2に示すように、人体の頭皮50の内側には頭蓋骨52がある。さらにその内側には、脳脊髄液54、灰白質56、および白質58がある。光源102から被検部40に向けて出射された光の一部は、頭皮50で反射され、光検出器104に向かう。光源102から出射された光の他の一部は、頭蓋骨52を通過して灰白質56および白質58に到達する。頭部内に侵入した光の一部は、脳または頭皮50の血液中のヘモグロビンに吸収される。吸収されなかった光の一部は、灰白質56および白質58などの脳組織によって繰り返し反射される。その光の一部は、頭皮50の外側に出て、光検出器104に向かう。光検出器104は、頭皮50で反射された光および脳組織を通過して戻ってきた光の少なくとも一部を、制御回路106による電子シャッタ機能を用いて検出する。図2における矢印は、この過程における光の伝搬経路の一例を示している。 As shown in FIG. 2, a skull 52 is inside the scalp 50 of the human body. More inside, cerebrospinal fluid 54, gray matter 56, and a white matter 58. Some from the light source 102 of light emitted toward the object part 40 is reflected by the scalp 50, toward the optical detector 104. Another portion of the light emitted from the light source 102 passes through the skull 52 to reach the gray matter 56 and the white matter 58. A portion of the light that has entered the head is absorbed by the hemoglobin in the blood of the brain or scalp 50. Some of unabsorbed light is repeatedly reflected by the brain tissues, such as gray matter 56 and white matter 58. A portion of the light exits the scalp 50 and travels to the light detector 104. The light detector 104 detects at least a portion of the light reflected by the scalp 50 and the light returned through the brain tissue using an electronic shutter function by the control circuit 106. Arrows in FIG. 2 indicate an example of the light propagation path in this process.
 人が思考または運動を行うと、脳の活動領域において血液量が増加する。血液量の増加に伴い、ヘモグロビンの濃度が増加する。ヘモグロビンの濃度が増加すると、光の吸収率が増加するため、光検出器104によって検出される光の量は減少する。他方、皮膚血流も、自律神経の働きにより、心理状態を反映して変化することが知られている。したがって、光検出器104によって検出される光の量の変化を検出することにより、脳または頭皮における血流の状態を把握することができる。 When a person thinks or exercises, blood volume increases in the active area of the brain. With the increase of blood volume, the concentration of hemoglobin increases. As the concentration of hemoglobin increases, the rate of light absorption increases, so the amount of light detected by the light detector 104 decreases. On the other hand, skin blood flow is also known to change by reflecting the state of mind by the function of the autonomic nerve. Therefore, by detecting the change in the amount of light detected by the light detector 104, the state of blood flow in the brain or scalp can be grasped.
 図2の例では、光源102から出射される光は単一の波長の光である。この例に限定されず、複数の波長の光を組み合わせて用いてもよい。例えば、650nm以上805nm未満の波長の光と、805nmよりも長く950nm以下の波長の光とを組み合わせて用いてもよい。このような複数の波長の光を組み合せる構成は、酸素化ヘモグロビンの濃度と、脱酸素化ヘモグロビンの濃度との比に基づく制御を行う場合に特に有効である。酸素化ヘモグロビンおよび脱酸素化ヘモグロビンの吸収率は、上記の2つの波長領域において異なる。このため、これらの2つの波長領域に属する2種類の光を用いて得られた2つの電気信号を演算することにより、脳血液中の酸素化ヘモグロビンおよび脱酸素化ヘモグロビンの割合を測定することができる。 In the example of FIG. 2, the light emitted from the light source 102 is light of a single wavelength. The present invention is not limited to this example, and light of a plurality of wavelengths may be used in combination. For example, a light having a wavelength of less than 650 nm 805 nm, may be used in combination with light of longer 950nm wavelength below than 805 nm. Construction combining light of such a plurality of wavelengths is particularly effective when carried out with a concentration of oxygenated hemoglobin, the control based on the ratio of the concentration of deoxygenated hemoglobin. The absorption rates of oxygenated hemoglobin and deoxygenated hemoglobin differ in the above two wavelength regions. For this reason, it is possible to measure the proportion of oxygenated hemoglobin and deoxygenated hemoglobin in cerebral blood by calculating two electrical signals obtained using two types of light belonging to these two wavelength regions. it can.
 光源102による光の照射および光検出器104による検出のタイミングは、制御回路106によって同期して制御される。光検出器104によって検出された光の量を示す電気信号は、信号処理回路108によって処理される。信号処理回路108は、当該電気信号に基づいて、例えば酸素化ヘモグロビンの濃度分布を示す信号を、血流情報として生成して出力する。この血流情報は、図1に示す制御装置500に送られる。 The timing of the light emission by the light source 102 and the detection by the light detector 104 are controlled synchronously by the control circuit 106. Electrical signal indicative of the amount of light detected by the photodetector 104 is processed by the signal processing circuit 108. The signal processing circuit 108, based on the electric signal, for example, a signal indicative of the concentration distribution of oxygenated hemoglobin, and generates and outputs a blood flow information. This blood flow information is sent to the control unit 500 shown in FIG.
 制御装置500は、検出装置100から取得した血流情報に基づいて、アトラクション装置200の動作を制御する。例えば、制御装置500は、血流情報の変化に応じて、アトラクション装置200からユーザに提供される少なくとも一つの刺激の大きさまたは刺激の種類を変化させる。これにより、例えばアトラクション中に恐怖を感じていないユーザに、より大きい刺激または異なる種類の刺激を与えて恐怖心を感じさせるようにすることができる。 The control device 500, based on the acquired blood flow information from the detecting device 100, controls the operation of the attraction device 200. For example, the controller 500 changes the magnitude or type of at least one stimulus provided from the attraction device 200 to the user in response to the change in blood flow information. Thus, for example, the user who does not feel fear during attraction, it is possible to make feel fear giving greater stimulation or different types of stimuli.
 アトラクションシステム10は複数の検出装置100を備え、複数の検出装置100の各々は、対応する複数のユーザ600の各々の血流情報を検出可能に構成されていてもよい。アトラクション装置200は、複数のユーザ600の各々に対する刺激を個別に制御可能に構成されていてもよい。そのような形態では、制御装置500は、複数の検出装置100から複数のユーザの血流情報を取得し、複数のユーザ600の各々の血流情報に基づいて、複数のユーザ600の各々に対する刺激を個別に制御する。 Attraction system 10 includes a plurality of detecting devices 100, each of the plurality of detecting devices 100 may be detectably configuration blood flow information of each of the corresponding plurality of users 600. The attraction apparatus 200 may be configured to be able to individually control the stimulation for each of the plurality of users 600. In such form, the control unit 500 obtains blood flow information of a plurality of users from a plurality of detecting devices 100, based on each of the blood flow information of a plurality of users 600, stimulus for each of the plurality of users 600 Control individually.
 例えば、非特許文献1、2に記載されているように、恐怖の感情は、脳内の扁桃体および前頭前野に深く関連することが知られている。恐怖感情を誘起させる刺激が被検者に提供された場合、その情報は、視床から感覚野へと伝達され、前頭前野に到達する。さらに前頭前野から扁桃体へ情報が伝わり、その結果、扁桃体において恐怖感情が発露すると考えられている。そのため、光学的な方法により、前頭前野領域における脳活動を計測することができれば、被検者が恐怖の感情を抱いているかどうかを類推することができる。 For example, as described in Non-Patent Documents 1 and 2, it is known that the feeling of fear is deeply related to the amygdala and the prefrontal cortex in the brain. When a stimulus that causes fear is provided to the subject, the information is transmitted from the thalamus to the sensory area to reach the prefrontal area. Further information is transmitted from the prefrontal cortex to the amygdala, resulting in fear emotion amygdala is believed to manifestation. Therefore, if it is possible to measure brain activity in the prefrontal region by an optical method, it can be analogized whether the subject feels fear or not.
 他方、非特許文献3は、恐怖感情を誘起する映像を複数の被検者に提示した際に、前頭前野領域の酸素化ヘモグロビン量を計測した実験を開示している。その結果によると、通常の映像を提示した場合と比較して、恐怖の感情を誘起する映像を提示した際には、酸素化ヘモグロビン量が増加する。さらにその変化量には男女で差があることがわかった。参考のため、非特許文献3のFig.3を、図3として引用する。図3は、非特許文献3に開示された、当該実験の結果を示している。また以下の表1は、当該実験の結果を示している。表1内に記載されている数値は、中性的な刺激または恐怖の感情を誘起する刺激である恐怖刺激が与えられた場合に計測された酸素化ヘモグロビン濃度を示す。 On the other hand, Non-Patent Document 3 discloses an experiment in which the amount of oxygenated hemoglobin in the prefrontal area is measured when images causing fear emotion are presented to a plurality of subjects. According to the result, as compared with the case of presenting a normal video, when presented images which induces feelings of fear, oxygenated hemoglobin is increased. Further on the amount of change was found that there is a difference in men and women. For reference, FIG. 3 is quoted as FIG. FIG. 3 shows the result of the experiment disclosed in Non-Patent Document 3. The Table 1 below shows the results of the experiment. The numerical values listed in Table 1 indicate the oxygenated hemoglobin concentration measured when given a fear stimulus, which is a stimulus that induces a neutral stimulus or a feeling of fear.
Figure JPOXMLDOC01-appb-T000001
Figure JPOXMLDOC01-appb-T000001
 当該実験において、複数の男性に、中性的な刺激である通常の映像を提示した際の酸素化ヘモグロビンの濃度の平均値は0.0141であり、恐怖刺激である恐怖の感情を誘起する映像を提示した場合の酸素化ヘモグロビンの濃度の平均値は0.0156であった。他方、複数の女性に通常の映像を提示した際の酸素化ヘモグロビンの濃度の平均値は0.0071であり、恐怖の感情を誘起する映像を提示した場合の酸素化ヘモグロビンの濃度の平均値は0.0279であった。 In this experiment, the average value of the concentration of oxygenated hemoglobin at the time of presenting a normal image that is a neutral stimulus to a plurality of men is 0.0141, and an image that induces a feeling of fear that is a fear stimulus the average value of the concentration of oxygenated hemoglobin in the case of presenting was 0.0156. On the other hand, the average value of the concentration of oxygenated hemoglobin at the time of presenting a normal image to a plurality of women is 0.0071, and the average value of the concentration of oxygenated hemoglobin at the time of presenting an image inducing a feeling of fear is It was 0.0279.
 この実験によれば、恐怖の感情を誘起する映像を提示した場合の酸素化ヘモグロビンの濃度の増加率は、男性では1.11倍にすぎなかったが、女性では3.93倍と高い値を示した。この結果から、恐怖心に対する酸素化ヘモグロビンの変化率に関しては男女差が大きいことがわかる。この実験は酸素化ヘモグロビンの濃度に関して行われたが、心拍数などの他の生体情報についても、同様に男女差があることが推定される。 According to this experiment, the increase rate of the concentration of oxygenated hemoglobin at the time of presenting the image that induces the feeling of fear is only 1.11 times in men, but it is a high value 3.93 times in women Indicated. From this result, it can be seen that there is a large gender difference in the rate of change of oxygenated hemoglobin with respect to fear. Although this experiment was performed with respect to the concentration of oxygenated hemoglobin, it is presumed that there is also a gender difference for other biological information such as heart rate.
 したがって、生体情報に基づいてアトラクション装置を制御する場合、ユーザの性別を考慮して制御することが有効と考えられる。例えば、前述の検出装置による頭皮血流または脳血流に関する情報と性別情報とを組み合わせて、適切な酸素化ヘモグロビン濃度の変化量の閾値を設定することが有効と考えられる。平常時の酸素化ヘモグロビン濃度に対する刺激提示後の酸素化ヘモグロビン濃度の増加率が、性別に基づいて決定された閾値を超えているか否かに基づいて、ユーザが恐怖を感じているか否かをより正確に判断することができる。 Therefore, when controlling an attraction apparatus based on biometric information, it is considered effective to control in consideration of the gender of the user. For example, it is considered effective to set an appropriate threshold value of the change amount of oxygenated hemoglobin concentration by combining information on the scalp blood flow or cerebral blood flow by the above-mentioned detection device and gender information. Based on whether the increase rate of oxygenated hemoglobin concentration after stimulation presentation for normal oxygenated hemoglobin concentration exceeds the threshold determined based on gender, whether the user feels fear or not It can be judged accurately.
 脳の前頭前野領域は脳の高次な機能の発露に関与しており、特に実行機能(executive function)を行うと考えられている。実行機能は3つの要素から構成されていると考えられている。3つの要素は、抑制(inhibition)、課題ルールのシフト(shifting)、情報の更新(updating)である。非特許文献4に記載されているように、これらの実行機能は、社会的な環境という複雑な課題に適合するために必須の機能であり、乳幼児期から青年期にかけて大きく成熟すると考えられている。例えば、非特許文献5には、6歳児と大人とで、Go/No Goタスク実行時の前頭前野の脳血流の反応が異なることが報告されている。Go/No Goタスクとは、ターゲットが提示された時にボタンを押し(Go)、オフターゲットが提示された時にはボタンを押さない(No Go)ように教示されるタスクである。非特許文献5によれば、大人の場合、No Go実行時に右脳の前頭葉が活性化し、6歳児ではGo、No Goいずれの実行時でも右脳の前頭葉が活性化される。これは、大人の場合、実行機能が成熟し、抑制が必要なNo Go提示時に実行機能が作動し、右脳前頭葉の脳血流が増加するためと考えられる。一方で、6歳児の場合、実行機能の制御が未成熟であるため、いずれの課題が提示された時でも脳血流が増加するものと考えられる。 The prefrontal region of the brain is involved in the development of higher functions of the brain, and is considered to be particularly responsible for an executive function. The executive function is considered to be composed of three elements. The three elements are inhibition, shifting of task rules, and updating of information. As described in Non-Patent Document 4, these executive functions are essential functions to meet the complex problems of the social environment, and are considered to be largely matured from infancy to adolescence . For example, Non-Patent Document 5 reports that the response of the cerebral blood flow in the prefrontal cortex at the time of execution of a Go / No Go task differs between a 6-year-old child and an adult. The Go / No Go task is a task instructed to press a button (Go) when a target is presented, and not press a button (No Go) when an off target is presented. According to Non-Patent Document 5, the frontal lobe of the right brain is activated at the time of No Go in the case of adults, and the frontal lobe of the right brain is activated at the time of any of Go and No Go in 6-year-old children. This is because, in the case of an adult, executive function matures, suppression is activated run capability when required No Go presentation, presumably because cerebral blood flow right brain frontal lobe increases. On the other hand, in the case of a 6-year-old child, control of executive function is immature, so it is considered that cerebral blood flow increases even when any task is presented.
 さらに、この実行機能は加齢とともに衰えることが知られている。例えば、非特許文献6では、21から32歳の健康な若者および64から81歳の健康な老人に対して、実行機能を調べるタスクとして知られているN-back課題実行時の前頭前野の脳血流の変化が計測された。この時、若者の群ではタスク実行時に脳血流の増加が見られ、特に右脳側の脳血流が強く増加したのに対して、老人の場合、左右の脳の脳血流が等しく増加した。 Furthermore, it is known that this executive function declines with age. For example, in Non-Patent Document 6, the brain of the prefrontal cortex at the time of executing the N-back task known as a task for examining executive functions for healthy young people aged 21 to 32 and healthy old people aged 64 to 81. Changes in blood flow were measured. At this time, in the group of adolescents, cerebral blood flow was increased at task execution, and in particular, cerebral blood flow in the right brain side was strongly increased, while in the case of old people, cerebral blood flow in the left and right brains was equally increased. .
 これらのことにより、前頭前野領域の脳血流は、幼児、成人、老人の3区分において実行機能を発揮させる際に異なる領域、異なる強度で変化する。また、非特許文献7では、前頭前野の脳血流は、実行機能を発揮させる際に変化するだけでなく、感情を処理する際にも変化することが報告されている。健常の女性に恐怖画像を提示し、恐怖感情を表出させた場合、左右の前頭前野の脳血流が増加し、この恐怖感情を抑制するように指示した場合、左脳の前頭前野領域の脳血流が顕著に増加した。 By these, cerebral blood flow in the prefrontal region, infants, adults, different areas when exerting execution function in three categories: the elderly, varies with different intensities. In addition, Non-Patent Document 7 reports that the cerebral blood flow in the prefrontal cortex not only changes upon exerting an executive function, but also changes when processing emotions. When a fear image is presented to a healthy woman and fear is expressed, the cerebral blood flow in the left and right prefrontal areas increases, and when it is instructed to suppress this fear, the brain in the prefrontal region of the left brain Blood flow was significantly increased.
 以上のことから、アトラクション装置から搭乗者に感情的な刺激が与えられた場合、搭乗者の前頭前野領域の脳血流の変化が誘導されると考えられる。その時の脳血流の変化量と変化する領域は、搭乗者の性別、世代、さらに搭乗者の感情の発露の様式によると想定される。感情の発露の様式とは、本人が感情を感じた際にその感情を素直に表出するか、感情を表出せずに抑制しようとするかである。 From the above, if the emotional stimulus attraction device passenger is given is considered to change in cerebral blood flow prefrontal region of the occupant is induced. It is assumed that the amount of change in cerebral blood flow and the area of change at that time depend on the gender of the passenger, the generation, and the mode of expression of the emotion of the passenger. The style of the manifestation of emotions, is whether in person or not to obediently expose the emotion when you feel the emotion, trying to suppress without expose the emotion.
 したがって、搭乗者の性別または年齢層などの属性情報、および予備的な刺激を与えたときの血流情報の全てまたは一部を、実際のアトラクションの開始前、またはアトラクションの途中に取得することが有効と考えられる。取得したこれらの情報に基づき、搭乗者の感情状態を推定することができる。例えば、搭乗者の感情状態を推定するために用いられる脳血流情報の変化量の閾値、および/または脳血流情報を取得する領域である検出部位を、取得した情報に基づいて決定または変更することができる。 Therefore, attribute information such as the gender or age group of the passenger, and all or part of the bloodstream information when the preliminary stimulation is given, may be acquired before the start of the actual attraction or in the middle of the attraction It is considered effective. The emotional state of the passenger can be estimated based on the acquired information. For example, based on the acquired information, determination or change of a threshold of a change amount of cerebral blood flow information used to estimate a passenger's emotional state and / or a detection site which is an area for acquiring cerebral blood flow information can do.

 脳血流計測指示ユニット532は、ヘッドマウントディスプレイ300における検出装置100内の制御回路106に、ユーザ600の脳血流情報を取得すべき旨の信号を送信する。検出装置100内の制御回路106は、この信号に応答して、光源102から所定の光を出射させる。 The cerebral blood flow measurement instruction unit 532 transmits a signal to the effect that the cerebral blood flow information of the user 600 should be acquired to the control circuit 106 in the detection device 100 in the head mounted display 300. The control circuit 106 in the detection device 100, in response to this signal, the light source 102 to emit a predetermined light.
 光源102から出射される光の波長、強度、照射時間、および照射パターンは特定のものに限定されない。使用される光の波長は、脳血流情報を取得できる波長であればよい。光源102は、例えば650nm以上950nm以下の光を出射する。この波長範囲は、赤色から近赤外線の波長範囲に含まれる。この波長範囲は、生体の窓と呼ばれ、体内での吸収率が低いことで知られている。本実施形態における光源102は、上記の波長範囲の光を出射するものとするが、他の波長範囲の光を用いてもよい。なお、本明細書では、可視光のみならず赤外線についても、「光」の用語を用いる。 Wavelength of light emitted from the light source 102, intensity, irradiation time, and irradiation pattern is not limited to a specific one. The wavelength of light to be used may be a wavelength at which cerebral blood flow information can be obtained. The light source 102 emits light of, for example, 650 nm or more and 950 nm or less. This wavelength range is included in the red to near infrared wavelength range. This wavelength range is called the biological window, known by low absorption rate in the body. The light source 102 in this embodiment emits light in the above wavelength range, but light in other wavelength ranges may be used. In the present specification, for the infrared not only visible light, using the term "light".
 光源102は、例えば、パルス光を繰り返し出射するレーザダイオード(Laser Diode)等の光源であり得る。光源102としてレーザ光源を用いる場合、例えば、各国で策定されるレーザ安全基準のクラス1を満足するレーザ光源が選択される。クラス1が満足されている場合、被爆放出限界AELが1mWを下回るほどの低照度の光が出射される。低照度の光のため、光検出器104の感度が不足する場合は、パルス光を繰り返し出射し、それらのパルス光を繰り返し光検出器104に蓄積させてもよい。光源102は、レーザ光源に限らず、発光ダイオード(Light Emitting Diode)などの他の種類の光源であってもよい。光源102は、パルス光ではなく、定常光を出射するように構成されていてもよい。 The light source 102 may be, for example, a light source such as a laser diode that repeatedly emits pulsed light. When a laser light source is used as the light source 102, for example, a laser light source that meets class 1 of the laser safety standard formulated in each country is selected. If a class 1 is satisfied, exposure release limit AEL low illuminance of light as less than 1mW is emitted. If the sensitivity of the light detector 104 is insufficient due to the low illuminance light, the pulse light may be repeatedly emitted, and the pulse light may be repeatedly accumulated in the light detector 104. The light source 102 is not limited to a laser light source, and may be another type of light source such as a light emitting diode. The light source 102 may be configured to emit stationary light instead of pulsed light.
 光源102からの光はユーザ600の額部に照射される。照射された光の一部は、ユーザ600の額部の内部を伝搬し、脳血流の情報を含む光として光検出器104に入射する。光検出器104は、制御回路106によって光源102の動作と同期して制御される。 Light from the light source 102 is irradiated to the forehead of the user 600. Some of the irradiated light is propagated through the inside of the forehead of the user 600, and enters the optical detector 104 as a light containing information of cerebral blood flow. The light detector 104 is controlled by the control circuit 106 in synchronization with the operation of the light source 102.
 光検出器104は、例えばフォトダイオードを有する。ある例では、光検出器104は、2次元的に配列された複数のフォトダイオードを含むイメージセンサであり得る。フォトダイオードは、光電変換によって受光量に応じた電気信号を出力する。光検出器104は、この電気信号を増幅する増幅器、およびアナログ信号をデジタル信号に変換するA/D変換器を備えていてもよい。光検出器104から出力された信号は、信号処理回路108に送られる。 The photodetector 104 includes, for example, a photodiode. In one example, the light detector 104 may be an image sensor that includes a plurality of two-dimensionally arranged photodiodes. The photodiode outputs an electrical signal according to the amount of light received by photoelectric conversion. Optical detector 104, an amplifier for amplifying the electrical signal, and the analog signal may comprise an A / D converter for converting a digital signal. The signal output from the light detector 104 is sent to the signal processing circuit 108.
 信号処理回路108は、光検出器104から出力された信号を加工して制御装置500に送る。ユーザ600の身体または額部の動きに起因して信号の飛び値が生じたり、脳血流波形に心拍、脈波、または脳波に由来すると考えられる周期的なノイズが混入したりする可能性がある。その場合、正確な脳血流の計測が実現されない。そこで、信号処理回路108は、取得した信号から、飛び値または周期的な変動成分を除去したデータを生成して出力する。 The signal processing circuit 108 sends to the controller 500 a signal outputted from the photodetector 104 processed to. Motion of the body or forehead of the user 600 may cause jumps in the signal, or the cerebral blood flow waveform may be mixed with periodic noise that may be derived from heart beat, pulse wave, or electroencephalogram is there. In that case, it is not realized accurate measurement of cerebral blood flow. Therefore, the signal processing circuit 108 generates and outputs data from which the jump value or the periodic fluctuation component is removed from the acquired signal.
 制御装置500における信号処理回路550は、検出装置100における信号処理回路108から当該データを取得する。信号処理回路550における処理ユニット551は、取得したデータから酸素化ヘモグロビンの濃度を算出し、ユーザ600の生理情報および性別情報と関連付けてメモリ570に記録する。 The signal processing circuit 550 in the control device 500 obtains the data from the signal processing circuit 108 in the detection device 100. Processing in the signal processing circuit 550 unit 551 calculates the concentration of oxyhemoglobin from the acquired data is recorded in the memory 570 in association with the physiological information and gender information of the user 600.
 ヘッドマウントディスプレイ300のディスプレイ302に表示される映像は、制御装置500内の映像出力指示ユニット533から出力される。映像出力指示ユニット533は、制御ユニット531に制御される。制御ユニット531は、メモリ570に記録されたユーザ600の脳血流などの情報に基づいて適切な映像を選択し、映像出力指示ユニット533を介してディスプレイ302に表示を指示する。 An image displayed on the display 302 of the head mounted display 300 is output from an image output instruction unit 533 in the control device 500. Video output instruction unit 533 is controlled by the control unit 531. The control unit 531 selects an appropriate image based on the information such as the cerebral blood flow of the user 600 recorded in the memory 570, and instructs the display 302 to display via the image output instruction unit 533.
 ヘッドマウントディスプレイ300における性別入力装置303は、ユーザ600の性別情報を取得する装置である。例えば図5に示される例では、性別入力装置303は、男性ボタンおよび女性ボタンを備える。アトラクション開始時に、ユーザ600またはアトラクション装置の係員700がいずれかのボタンを押すことにより、そのユーザ600の性別を設定することができる。この性別情報は、制御装置500の信号処理回路550に送られ、メモリ570に保存される。 The gender input device 303 in the head mounted display 300 is a device for acquiring gender information of the user 600. For example, in the example shown in FIG. 5, the gender input device 303 includes a male button and a female button. At the start of the attraction, the user 600 or the attendant 700 of the attraction apparatus can set the gender of the user 600 by pressing one of the buttons. The gender information is sent to the signal processing circuit 550 of the controller 500, it is stored in the memory 570.
 次に、アトラクション装置200におけるライド装置210および刺激ユニット220の構成をより詳細に説明する。 Next, the configurations of the ride device 210 and the stimulation unit 220 in the attraction device 200 will be described in more detail.

Skin stimulator 218 includes an electrically conductive material to provide electrical stimulation at a specific timing to the user 600. The timing, intensity and duration at which the stimulation is applied are controlled by the stimulation indication unit 535 in the controller 500.

 (動作)
 次に、図7および図8を参照しながら、本実施形態の動作を説明する。
(Operation)
Next, the operation of the present embodiment will be described with reference to FIGS. 7 and 8.
 図7は、本実施形態におけるアトラクションシステムの処理フローを示すシーケンス図である。 FIG. 7 is a sequence diagram showing a processing flow of the attraction system in the present embodiment.
 まず、アトラクションシステムの係員700が、制御装置500の入力インタフェース510を介して、アトラクションの開始通知を入力する(ステップS501)。すると、アトラクションの開始の通知を示す信号が、制御装置500からヘッドマウントディスプレイ300のディスプレイ302に送られる。ディスプレイ302は、ユーザ600にアトラクションの開始を通知する映像を表示する(ステップS301)。この映像には、ユーザ600に性別の入力を促す指示が含まれる。ユーザ600は、この指示に従い、性別入力装置303を操作して性別を入力する(ステップS303)。性別情報は、制御装置500に送られ、メモリ570に保存される(ステップS503)。 First, the clerk 700 attractions systems, via the input interface 510 of the controller 500, inputs a start notification of attraction (step S501). Then, a signal indicating notification of the start of an attraction is sent from the control device 500 to the display 302 of the head mounted display 300. Display 302 displays an image for notifying the start of the attraction to the user 600 (step S301). This video includes instructions to the user 600 prompts the input of the sex. In accordance with this instruction, the user 600 operates the gender input device 303 to input gender (step S303). Gender information is sent to the controller 500, are stored in the memory 570 (step S503).
 次に、制御装置500における脳血流計測指示ユニット532および生理情報計測指示ユニット534は、ユーザ600の生理情報および脳血流情報を計測すべき旨の指示を、アトラクション装置200およびヘッドマウントディスプレイ300にそれぞれ送信する(ステップS505)。この動作は、平常状態におけるユーザの生理情報および脳血流情報を取得するために行われる。アトラクション装置200における生理情報計測装置217は、この指示に従い、ユーザ600の生理情報を取得し、制御装置500に送信する(ステップS205)。ヘッドマウントディスプレイ300における検出装置100は、脳血流情報の計測指示に従い、ユーザの脳血流情報を取得し、制御装置500に送信する(ステップS305)。この脳血流情報を第1の血流情報と称する。取得された脳血流情報および生理情報は、制御装置500における処理ユニット551によって処理され、メモリ570に保存される(ステップS507)。 Next, the cerebral blood flow measurement instruction unit 532 and the physiological information measurement instruction unit 534 in the control device 500 instruct the attraction device 200 and the head mount display 300 to instruct to measure the physiological information and the cerebral blood flow information of the user 600. respectively transmit (step S505). This operation is performed to obtain the physiological information and the cerebral blood flow information of the user in the normal state. The physiological information measurement device 217 in the attraction device 200 acquires physiological information of the user 600 according to this instruction, and transmits the physiological information to the control device 500 (step S205). The detection device 100 in the head mounted display 300 acquires cerebral blood flow information of the user according to the measurement instruction of cerebral blood flow information, and transmits the information to the control device 500 (step S305). The cerebral blood flow information is referred to as a first blood flow information. The acquired cerebral blood flow information and physiological information are processed by the processing unit 551 in the control device 500 and stored in the memory 570 (step S507).
 信号処理回路550における処理ユニット551は、取得した脳血流情報および生理情報の正常性を判断する(ステップS509)。脳血流情報または生理情報に異常値が含まれている場合、制御装置500は、ステップS505における脳血流情報または生理情報の計測指示を再度行う。例えば、脳血流情報を正常に取得できなかった場合、制御装置500は、ディスプレイ302に、例えばヘッドマウントディスプレイ300の再装着をユーザに指示する映像を表示させてもよい。この場合、ヘッドマウントディスプレイ300は、ユーザ600が再装着した後、再び脳血流情報を取得する。取得された生体情報に異常値がなかった場合は、次のステップS511に進む。 Processing in the signal processing circuit 550 unit 551 determines the normality of the acquired cerebral blood flow information and the physiological information (step S509). If the cerebral blood flow information or the physiological information includes an abnormal value, the control device 500 re-executes the measurement instruction of the cerebral blood flow information or the physiological information in step S505. For example, when the cerebral blood flow information can not be acquired normally, the control device 500 may cause the display 302 to display an image instructing the user to reattach the head mounted display 300, for example. In this case, the head mounted display 300 acquires cerebral blood flow information again after the user 600 reattaches. If no abnormal value is contained in the acquired biometric information, the process proceeds to the next step S511.
 制御装置500は、制御回路530における刺激指示ユニット535を介して、アトラクション装置200およびヘッドマウントディスプレイ300に、刺激の提供を指示する制御信号を送信する(ステップS511)。ヘッドマウントディスプレイ300は、制御信号に従い、ディスプレイ302に新たな映像を表示し、ユーザ600に映像の刺激を提供する(ステップS311)。同時に、アトラクション装置200は、制御信号に従い、ライド装置210および刺激指示ユニット535を駆動して、映像への没入感を高めるための動き、匂い、風、音、温度などの刺激をユーザ600に与える(ステップS211)。これらの刺激を、まとめて第1の刺激と称する。 Control device 500 transmits a control signal for instructing provision of stimulation to attraction device 200 and head mounted display 300 via stimulation instruction unit 535 in control circuit 530 (step S511). Head-mounted display 300 in accordance with the control signal, to display a new image on the display 302, it provides the stimulus image to the user 600 (step S311). At the same time, the attraction apparatus 200 drives the ride apparatus 210 and the stimulation instruction unit 535 in accordance with the control signal to provide the user 600 with a stimulus such as a motion, a smell, a wind, a sound or a temperature to enhance immersion in the image. (step S211). These stimuli, referred to collectively as the first stimulus.
 続いて、制御装置500は、これらの新しい刺激に対するユーザ600の恐怖度を計測するために、再度、脳血流情報および生理情報の計測指示を、ヘッドマウントディスプレイ300およびアトラクション装置200に送る(ステップS513)。この指示に基づき、ヘッドマウントディスプレイ300およびアトラクション装置200は、ユーザ600の脳血流情報および生理情報をそれぞれ取得し、制御装置500に送信する(ステップS213、S313)。ここで取得された脳血流情報を第2の血流情報と称する。取得された脳血流情報および生理情報は、制御装置500における処理ユニット551によって処理される。処理ユニット551は、例えば、取得した脳血流のデータにおける心拍または脳波などの周期的なノイズ成分の除去、および激しい体動によって生じる外れ値の除去などの前処理を行う。処理されたデータは、メモリ570に保存される(ステップS515)。 Subsequently, in order to measure the degree of fear of the user 600 with respect to these new stimuli, the control device 500 again sends measurement instructions of cerebral blood flow information and physiological information to the head mounted display 300 and the attraction device 200 (step S513). Based on this instruction, the head mounted display 300 and the attraction apparatus 200 respectively acquire cerebral blood flow information and physiological information of the user 600, and transmit the information to the control apparatus 500 (steps S213 and S313). The cerebral blood flow information obtained here is referred to as a second blood flow information. The acquired cerebral blood flow information and physiological information are processed by the processing unit 551 in the control device 500. The processing unit 551 performs preprocessing such as, for example, removal of periodic noise components such as heart beats or brain waves in acquired cerebral blood flow data, and removal of outliers generated by intense body movement. The processed data is stored in the memory 570 (step S515).
 次に、制御装置500の信号処理回路550は、ステップS507およびS515において保存された信号を比較して、ユーザ600の恐怖度を算出する(ステップS517)。例えば、信号処理回路550は、ステップS507で保存された第1の血流情報と、ステップS515で保存された第2の血流情報との変化量を計算する。この処理は、恐怖度演算ユニット553によって行われる。この変化量は、ユーザ600の恐怖度を反映する。制御装置500の制御回路530は、算出されたユーザ600の恐怖度に応じた刺激の内容を決定する(ステップS519)。例えば、制御回路530は、上記の変化量と、予め性別ごとに設定された閾値とを比較し、比較結果に基づいて、ユーザに提供する刺激の内容を決定する。 Next, the signal processing circuit 550 of the control device 500 compares the signals stored in steps S507 and S515 to calculate the degree of fear of the user 600 (step S517). For example, the signal processing circuit 550 calculates the amount of change between the first blood flow information stored in step S507 and the second blood flow information stored in step S515. This process is performed by the fear degree calculation unit 553. This variation reflects the fear of the user 600. The control circuit 530 of the control unit 500 determines the content of the stimulation in response to the fear of the user 600 is calculated (step S519). For example, the control circuit 530 compares the amount of change with the threshold set in advance for each gender, and determines the content of the stimulus to be provided to the user based on the comparison result.
 図8は、ステップS517およびステップS519における処理の例を具体的に示すフローチャートである。本実施形態では、恐怖度を判定するために、前頭前野領域、特に、左右の腹外側前頭前野(ventrolateral prefrontal cortex)における酸素化ヘモグロビンの濃度が用いられる。制御装置500における信号処理回路550は、刺激の提供の前後で当該領域の酸素化ヘモグロビン濃度を算出し、その変化量ΔOxyを計算する(ステップS801)。ここで変化量とは、差分または変化率を意味する。続いて、信号処理回路550における恐怖度演算ユニット553は、メモリ570に記録された性別情報を参照し、ユーザ600が男性か女性かを判断する(ステップS802)。ユーザ600が男性の場合、恐怖度演算ユニット553は、酸素化ヘモグロビン変化量の閾値S1を参照し、ΔOxyと比較する(ステップS803)。ΔOxyの方がS1よりも大きい場合、ユーザ600の恐怖度が大きいと判定される(ステップS805)。逆に、ΔOxyがS1以下の場合、恐怖度が小さいと判定される(ステップS806)。一方、ユーザ600の性別が女性の場合、恐怖度演算ユニット553は、判定の閾値として、S1よりも大きいS2を用いて、ΔOxyとS2とを比較する(ステップS804)。ΔOxyの方がS2よりも大きい場合、ユーザ600の恐怖度が大きいと判定される(ステップS805)。逆に、ΔOxyがS2以下の場合、恐怖度が小さいと判定される(ステップS807)。制御装置500における制御ユニット531は、ユーザ600の恐怖度の大、小に応じて、次にユーザ600に提供する刺激の内容を、予め用意された刺激判定基準を参照して決定する(ステップS809)。 Figure 8 is a flow chart showing an example of the processing in step S517 and step S519 in detail. In this embodiment, the concentration of oxygenated hemoglobin in the prefrontal region, in particular, the left and right ventral lateral prefrontal cortex is used to determine the fear level. The signal processing circuit 550 in the control device 500 calculates the oxygenated hemoglobin concentration in the region before and after the provision of the stimulus, and calculates the amount of change ΔOxy (step S801). Here, the change amount means a difference or a change rate. Subsequently, the fear degree calculation unit 553 in the signal processing circuit 550 refers to the sex information recorded in the memory 570, and determines whether the user 600 is a male or a female (step S802). When the user 600 is a male, the fear degree calculation unit 553 refers to the threshold value S1 of the oxygenated hemoglobin change amount and compares it with ΔOxy (step S803). If ΔOxy is larger than S1, it is determined that the degree of fear of the user 600 is high (step S805). Conversely, when ΔOxy is less than or equal to S1, it is determined that the fear level is small (step S806). On the other hand, when the gender of the user 600 is a female, the fear level computing unit 553 compares ΔOxy with S2 using S2 larger than S1 as the determination threshold (step S804). If ΔOxy is larger than S2, it is determined that the degree of fear of the user 600 is high (step S805). Conversely, if ΔOxy is less than or equal to S2, it is determined that the fear level is small (step S807). The control unit 531 in the control device 500 determines the content of the stimulus to be provided next to the user 600 with reference to the stimulation criteria prepared in advance, in accordance with the high or low degree of fear of the user 600 (step S809). ).
 刺激判定基準は、例えば以下の表2に示すような動作を規定するデータであり得る。 Stimulation criterion may be the data specifying the operation as shown for example in Table 2 below.
Figure JPOXMLDOC01-appb-T000002
Figure JPOXMLDOC01-appb-T000002
 恐怖度が大きいと判定された場合、判定後の刺激の強度は判定前の刺激と同程度に維持される。一方、恐怖度が小さいと判定された場合、ユーザ600はそのアトラクション装置に対して満足感が不十分であると推定される。このため、判定前の刺激と比較して、例えば、映像の恐怖度を高めたり、映像に対する没入感を高めたりする刺激が付加される(ステップS221及びステップS321)。このように、第1の変化量と閾値との比較結果に基づいて、アトラクション装置からユーザに提供される刺激の大きさまたは種類が適切に変更される。 If it is determined that the fear level is high, the intensity of the stimulus after the determination is maintained to the same extent as the stimulus before the determination. On the other hand, if it is determined that the fear small degree, the user 600 is satisfaction for the attraction device is estimated to be insufficient. Therefore, for example, a stimulus that enhances the fear of the image or enhances the sense of immersion in the image is added as compared with the stimulus before the determination (Step S221 and Step S321). In this manner, the magnitude or type of stimulus provided to the user from the attraction apparatus is appropriately changed based on the comparison result of the first variation and the threshold.
 なお、ここでは血流情報の変化のみに基づいて刺激を変化させる動作を例示したが、ステップS205およびS213でそれぞれ取得された生理情報も考慮され得る。例えば、図8のステップS803およびS804の判断に加えて、ステップS205およびS213でそれぞれ取得された生理情報の変化量も複合的に考慮して、ユーザの心理状態が判断され得る。この場合、血流情報の変化量と生理情報の変化量の両方に基づいて、ユーザに与える刺激の変化の態様が決定される。 In addition, although the operation | movement which changes a stimulus only based on the change of blood-flow information was illustrated here, the physiological information each acquired by step S205 and S213 may also be considered. For example, in addition to the determinations in steps S 803 and S 804 in FIG. 8, the psychological state of the user may be determined taking into consideration the amount of change in the physiological information acquired in steps S 205 and S 213 respectively. In this case, the aspect of the change in the stimulus given to the user is determined based on both the change in the blood flow information and the change in the physiological information.
 刺激の提供後、制御ユニット531は、アトラクションの進行を判断し、最後の刺激の提供が完了したかを判定する(ステップS523)。最後の刺激が完了していない場合は、再びステップS503に戻り、次の刺激について同じ動作を実行する。最後の刺激の提供が完了した場合、制御装置500は、アトラクションの終了を示す信号がアトラクション装置200およびヘッドマウントディスプレイ300に送信する(ステップS525)。この信号を受けて、ヘッドマウントディスプレイ300は、アトラクションの終了を示す映像を表示し、ユーザ600にアトラクションの終了を伝える。 After providing the stimulus, the control unit 531 determines the progress of the attraction determines whether provision of the last stimulus has been completed (step S523). If the last stimulus has not been completed, the process returns to step S 503 to execute the same operation for the next stimulus. When the provision of the last stimulus is completed, the control device 500 transmits a signal indicating the end of the attraction to the attraction device 200 and the head mounted display 300 (step S525). In response to this signal, the head mounted display 300 displays an image indicating the end of the attraction, convey the end of the attraction to the user 600.
 (効果および変形例)
 以上のように、本実施形態における制御装置500は、検出装置100から脳血流情報を取得し、当該脳血流情報に基づいて、アトラクション装置200の動作を制御する。脳血流情報は、ユーザの脳における血液中の酸素化ヘモグロビンの濃度を示す情報を含む。制御装置500は、脳血流情報の変化に応じて、ユーザに提供される少なくとも一つの刺激の大きさまたは刺激の種類を変化させる。より具体的には、制御装置500は、アトラクション装置200がユーザに一つの刺激を提供する前後における脳血流情報の変化を検出し、当該変化の大きさが閾値以下である場合に、当該ユーザに提供される刺激を大きくする。当該閾値は、入力されたユーザの性別によって異なる値に設定される。
(Effect and Modification)
As described above, the control device 500 in the present embodiment acquires cerebral blood flow information from the detection device 100, and controls the operation of the attraction device 200 based on the cerebral blood flow information. The cerebral blood flow information includes information indicating the concentration of oxygenated hemoglobin in the blood of the user's brain. The controller 500 changes the magnitude or type of stimulation provided to the user in response to changes in cerebral blood flow information. If More specifically, the control device 500 detects a change in cerebral blood flow information before and after the attraction device 200 provides one stimulus to the user, the size of the change is below a threshold, the user increasing the stimulation to be provided to. The threshold is set to a different value depending on the gender of the input user.
 このような構成により、ユーザの恐怖度に応じてユーザに提示される刺激の内容が適切に調整され、個々人の満足感を高めることができる。例えば、家族またはパートナーと同じアトラクションを共有したという共感を高めることができる。また、一つのアトラクションでありながら個人の嗜好に応じた満足感をユーザに提供することができる。 By this arrangement, it is adjusted to appropriate content of stimuli presented to the user in response to a user's fear of, it is possible to increase the satisfaction of the individual. For example, it is possible to increase the empathy that shared the same attraction with family or partner. In addition, it is possible to provide the user with a sense of satisfaction according to personal preference while being one attraction.
 上記の実施形態は一例に過ぎず、上記の実施形態に各種の変形を行ってもよい。例えば、アトラクション装置200がライド装置210と刺激ユニット220とに分かれている必要はない。ヘッドマウントディスプレイ300を使用することも必須の要件ではない。検出装置100およびディスプレイ302が、アトラクション装置200に設けられていてもよい。性別入力装置303および生理情報計測装置217を用いることも必須の要件ではない。ユーザに与えられる刺激は、上記の例に限定されず、ユーザの視覚、聴覚、触覚、嗅覚などの五感の少なくとも一部を刺激する限り、如何なる態様であってもよい。上記の実施形態におけるディスプレイ302、動き刺激装置219、皮膚刺激装置218、音響装置225、送風装置224、匂い発生装置226のいくつかを省略したり、上記とは全く異なる刺激を提供する装置を使用したりしてもよい。 The above embodiment is only an example, it may be subjected to various modifications to the above embodiment. For example, it is not necessary to attraction device 200 is divided into a ride device 210 and the stimulation unit 220. Not even mandatory requirement to use a head-mounted display 300. The detection device 100 and the display 302 may be provided in the attraction device 200. Not be essential requirement to use a sex input device 303 and the physiological information measuring device 217. The stimulus given to the user is not limited to the above example, and may be in any form as long as it stimulates at least a part of five senses such as the user's sense of sight, hearing, sense of touch and smell. In the above embodiment, the display 302, the motion stimulation device 219, the skin stimulation device 218, the acoustic device 225, the blower device 224, the odor generating device 226 may be omitted, or a device providing stimulation different from the above may be used. it may be or.
 (第2の実施形態)
 次に、搭乗者の年齢層に応じて異なる制御を行うアトラクションシステムの例を説明する。
Second Embodiment
Next, an example of attraction system to perform different control depending on the age of the passenger.
 本実施形態では、性別に加えて、年齢層の情報が属性情報として利用される。制御回路530は、ユーザの性別および年齢層を示す属性情報を取得し、取得した属性情報に基づき、当該ユーザの血流情報の変化量の閾値を決定する。制御回路530はまた、ユーザの年齢層に応じて、血流情報が取得される前頭部の領域の大きさを決定する。 In the present embodiment, in addition to the gender, the information age is used as attribute information. The control circuit 530 acquires attribute information indicating the gender and age group of the user, and determines the threshold of the amount of change in blood flow information of the user based on the acquired attribute information. The control circuit 530 also determines the size of the area of the forehead where blood flow information is to be obtained, according to the age group of the user.
 年齢層の区分は、未就学児(6歳以下程度)、大人(小学生以上65歳未満)、老人(65歳以上)である。アトラクションシステムの入力IF510を介して、各搭乗者の年齢層が入力される。入力は、ユーザ自身が行ってもよいし、係員のような第三者が入力してもよい。また、アトラクションシステムが備えるカメラによって取得される画像に基づいて、画像処理によって年齢層を判別してもよい。性別についても同様に、カメラによって取得される画像に基づいて判別してもよい。検出装置100における光検出器104がカメラとしての機能を有していてもよい。 The age groups are classified as pre-school children (about 6 years old or less), adults (more than elementary school students and less than 65 years old), and old people (65 years old or more). Via input IF510 attraction system, age of the rider is inputted. The input may be performed by the user himself or by a third party such as an attendant. Further, the age group may be determined by image processing based on an image acquired by a camera included in the attraction system. Similarly, the gender may be determined based on the image acquired by the camera. The light detector 104 in the detection device 100 may have a function as a camera.
 老人の場合、タスク実行時の脳血流の変化量が小さくなる傾向がある。また、脳機能局在が曖昧になるため、額領域全体における脳領域における脳血流情報が利用される。つまり、額領域全体における検出結果に基づいて変化量が算出される。例えば、額の全域における脳血流情報の変化量の平均値が用いられ得る。また、変化量の閾値は大人と比べて低く設定される。 For elderly tend to change the amount of cerebral blood flow during task execution is reduced. In addition, since cerebral function localization becomes vague, cerebral blood flow information in the brain area in the entire forehead area is used. In other words, the amount of change is calculated based on the detection result in the entire forehead region. For example, the average value of the variation in cerebral blood flow information in the entire region of the forehead can be used. Further, the threshold value of the amount of change is set lower than that of an adult.
 未就学児の場合、脳機能局在がまだ曖昧であるため、額領域全体から取得した脳血流変化量のデータを代表値の算出のために用いる。例えば、平均値が用いられ得る。大人と異なり刺激に対して敏感だが、変化量は大人とほとんど変わらない。そこで、未就学児については、脳血流情報の変化量の閾値は、大人と同様の値に設定される。 In the case of preschool children, since cerebral function localization is still unclear, data of cerebral blood flow variation obtained from the entire forehead area is used for calculation of representative values. For example, an average value may be used. It is sensitive to different from the adult stimulation, but the amount of change is almost the same as adults. Therefore, for preschool children, the threshold value of the amount of change in cerebral blood flow information is set to the same value as that for adults.
 本実施形態では、アトラクションの動作前、または動作の初期段階で、予備刺激が搭乗者に与えられる。予備刺激として、アトラクション中に検出したい感情と同等の感情を想起することが知られている、画像、音、匂い、振動などの刺激が用いられる。予備刺激は、例えば大人のみに与えられる。予備刺激が与えられているときの脳血流の変化量が計測される。計測結果に基づいて、アトラクション動作中に脳血流を計測する領域が決定される。 In the present embodiment, pre-stimulation is given to the passenger before or at an early stage of operation of the attraction. As a pre-stimulation, a stimulus such as an image, a sound, a smell, or a vibration, which is known to recall an emotion equivalent to an emotion to be detected during attraction, is used. Pre-stimulation, for example, is given only to adults. The amount of change in cerebral blood flow when prestimulation is given is measured. Based on the measurement results, the area of measuring the cerebral blood flow during attraction operation is determined.
 図9は、本実施形態の動作の一部を示すフローチャートである。本実施形態では、アトラクションの開始前、あるいはアトラクションの開始後、図7におけるステップS505の前に、図9の動作が実行される。他の動作については図7に示す動作と同様である。 Figure 9 is a flowchart showing a part of the operation of the present embodiment. In the present embodiment, the operation of FIG. 9 is performed before the start of the attraction or after the start of the attraction before step S505 in FIG. The other operations are similar to those shown in FIG.
 ステップS901において、ユーザの年齢層が判断される。搭乗者が未就学児または老人であると判断されると、ステップS902に進む。 In step S901, the age group of the user is determined. If it is determined that the passenger is a preschooler or an old man, the process proceeds to step S902.
 ステップS902において、ユーザの計測領域が、額部全領域に決定される。次に、ステップS903において、ユーザの年齢層が判断される。ユーザが未就学児である場合はステップS906に進み、ユーザが老人である場合はステップS904に進む。ステップS904において、老人用の閾値セットS1、S2が設定される。S1は女性用の閾値、S2は男性用の閾値である。 In step S902, the measurement area of the user is determined to be the entire forehead area. Next, in step S903, age of the user is determined. If the user is a preschoolers proceeds to step S906, if the user is elderly proceeds to step S904. In step S904, threshold sets S1 and S2 for elderly people are set. S1 is a threshold for women, and S2 is a threshold for men.
 ステップS901で搭乗者が大人であると判断されると、ステップS905に進む。ステップS905において、予備刺激が提供され、そのときの脳血流の計測結果から、計測領域が決定される。予備刺激は、例えばそのアトラクションによってユーザに与えられる刺激と同種の刺激であり得る。予備刺激を第2の刺激と称する。計測領域として、例えば、予備刺激に対する酸素化ヘモグロビン濃度の変化量が最も高い一部の領域が決定される。次にステップS906において、閾値セットS1、S2が設定される。閾値セットS1、S2は、ユーザが大人であるか、未就学児であるかによって異なる値に設定される。 When passenger in step S901 is determined to be an adult, the process advances to step S905. In step S905, preliminary stimulation is provided, and the measurement region is determined from the measurement result of the cerebral blood flow at that time. Priming may be, for example, stimulation of the stimulation of the same kind provided to the user by its attraction. The priming referred to as a second stimulus. As the measurement area, for example, a partial area where the amount of change in oxygenated hemoglobin concentration relative to the prestimulation is the highest is determined. Next, in step S906, threshold value sets S1 and S2 are set. The threshold sets S1 and S2 are set to different values depending on whether the user is an adult or a preschooler.
 このようにしてユーザ毎に決定された閾値セットS1、S2は、図7におけるステップS517において用いられる。本実施形態では、ユーザの性別だけでなく、年齢層も考慮して閾値S1、S2を設定することにより、ユーザの心理状態をより適切に判断することができる。 The threshold sets S1 and S2 thus determined for each user are used in step S517 in FIG. In the present embodiment, by setting the thresholds S1 and S2 in consideration of not only the gender of the user but also the age group, it is possible to more appropriately determine the user's mental state.
 また、ユーザが未就学児または老人である場合には、額部の全領域が計測領域として設定され、ユーザが大人である場合には、額部の一部が計測領域として設定される。ユーザが大人である場合には、ステップS305における第1の血流情報の取得よりも前に、以下の動作が行われる。
