 図1は、実施の形態1に係る検出システム10の構成例を示すブロック図である。図2は、実施の形態1に係るセンサデータ20の構成例を示す図である。図3は、実施の形態1に係る生体情報21の構成例を示す図である。
(Embodiment 1)
<System configuration>
FIG. 1 is a block diagram showing a configuration example of a detection system 10 according to the first embodiment. FIG. 2 is a diagram showing a configuration example of sensor data 20 according to the first embodiment. FIG. 3 is a diagram showing a configuration example of the biometric information 21 according to the first embodiment.
 検出システム10は、センサ11と、生体情報検出装置12と、管理装置13と、端末装置14とを含んで構成される。センサ11と、生体情報検出装置12と、管理装置13と、端末装置14とは、所定の通信ネットワークを通じて、データ又は情報を送受信できてよい。通信ネットワークは、有線又は無線のいずれであってもよい。 The detection system 10 includes a sensor 11, a biological information detection device 12, a management device 13, and a terminal device 14.

The communication network may be wired or wireless.
 センサ11は、監視エリア8の全体を監視できるよう、複数配置されてよい。 A plurality of sensors 11 may be arranged so that the entire monitoring area 8 can be monitored.
 センサ11は、レーダ方式のセンサであり、所定の周波数帯の電波を照射し、当該センサ11のセンシング範囲に存在する物体(例えば人物1)から反射される反射波を受信する。センサ11は、照射した電波と受信した反射波とを比較して、図2に示すセンサデータ20を生成する。センサ11は、ミリ波レーダ方式のセンサであってよい。ミリ波レーダ方式の例として、FMCW(Frequency Modulated Continuous Wave)方式、又は、ステップICW(Interrupted Continuous Wave)方式等が挙げられる。 The sensor 11 is a radar type sensor that emits radio waves in a predetermined frequency band and receives reflected waves reflected from an object (for example, a person 1) existing within the sensing range of the sensor 11. The sensor 11 compares the emitted radio wave and the received reflected wave to generate sensor data 20 shown in FIG. 2 . The sensor 11 may be a millimeter wave radar type sensor. Examples of millimeter wave radar systems include the FMCW (Frequency Modulated Continuous Wave) system and the step ICW (Interrupted Continuous Wave) system.
 センサデータ20では、図2に示すように、タイムスタンプと、検知情報と、信号情報とが対応付けられている。 In the sensor data 20, as shown in FIG. 2, time stamps, detection information, and signal information are associated with each other.
 タイムスタンプは、センサデータ20を得たタイミングを示す情報である。タイムスタンプの例として、時刻情報又はフレーム番号が挙げられる。 The time stamp is information indicating the timing at which the sensor data 20 was obtained. Examples of timestamps include time information or frame numbers.
 検知情報は、例えば、所定強度以上の反射波が得られた3次元空間上の位置(以下、反射点と称する)を示す情報、センサ11から反射点までの距離を示す情報、及び、反射点における反射強度を示す情報を含む。 The detection information includes, for example, information indicating a position in three-dimensional space where a reflected wave of a predetermined intensity or higher was obtained (hereinafter referred to as a reflection point), information indicating the distance from the sensor 11 to the reflection point, and information indicating the reflection point. Contains information indicating the reflection intensity at
 信号情報は、例えば、受信アンテナ毎のIQデータを含む。 The signal information includes, for example, IQ data for each receiving antenna.
 すなわち、センサデータ20は、センシング範囲に存在する物体の3次元空間における位置、形状、及び、時間的変化を示すデータであり、映像データのような解像度は有していないため、各人物の個人を特定することはできず、センサ11により人物のプライバシーを保護した状態でのデータ取得が可能である。 That is, the sensor data 20 is data that indicates the position, shape, and temporal changes of objects existing in the sensing range in three-dimensional space, and does not have the resolution of video data, so it It is not possible to identify the person, and the sensor 11 can obtain data while protecting the person's privacy.
 センサ11は、生成したセンサデータ20を管理装置13及び端末装置14へ送信する。 The sensor 11 transmits the generated sensor data 20 to the management device 13 and the terminal device 14.
 生体情報検出装置12は、各センサ11から受信したセンサデータ20に基づいて、図3に示す生体情報21を生成する。 The biological information detection device 12 generates biological information 21 shown in FIG. 3 based on the sensor data 20 received from each sensor 11.
 生体情報21では、図3に示すように、タイムスタンプと、検出人物情報と、バイタル値情報と、信頼度とが対応付けられている。 In the biometric information 21, as shown in FIG. 3, a time stamp, detected person information, vital value information, and reliability are associated with each other.
 タイムスタンプは、生体情報21が生成されたタイミングを示す情報である。タイムスタンプの例として、時刻情報が挙げられる。管理装置13は、生体情報21を生成した時刻を、当該タイムスタンプとする。 The time stamp is information indicating the timing at which the biometric information 21 was generated. An example of a timestamp is time information. The management device 13 sets the time when the biometric information 21 is generated as the time stamp.
 検出人物情報は、検出された人物1に関する情報である。検出人物情報は、人物IDと、人物位置と、人物姿勢を含む。人物IDは、検出された人物1を識別するためのIDである。人物位置は、人物IDが示す人物の監視エリア8における3次元空間上の位置を示す。人物姿勢は、人物IDが示す人物1の姿勢を示す。生体情報検出装置12は、センサデータ20の検知情報に基づいて、人物位置及び人物姿勢を特定する。 The detected person information is information regarding the detected person 1. The detected person information includes a person ID, a person position, and a person posture. The person ID is an ID for identifying the detected person 1. The person position indicates the position of the person indicated by the person ID in the three-dimensional space in the monitoring area 8. The person posture indicates the posture of the person 1 indicated by the person ID. The biological information detection device 12 identifies a person's position and posture based on the detection information of the sensor data 20.
 バイタル値情報は、検出された人物1の活動状態であるバイタル値に関する情報である。バイタル値の例として、呼吸数、呼吸の深さ、心拍数、血圧が挙げられる。生体情報検出装置12は、センサデータ20の検知情報の時間変化に基づいて、検出された人物1のバイタル値(例えば、呼吸数、呼吸の深さ、心拍数、血圧等)を算出する。 The vital value information is information regarding the vital value of the detected person 1, which is the active state.

 信頼度情報は、バイタル値情報の信頼度(尤度)を示す情報である。生体情報検出装置12は、センサデータ20の検知情報及び信号情報に基づいて、算出されたバイタル値情報の信頼度を算出する。なお、信頼度情報は、バイタル値情報の算出源であるレーダ信号のノイズレベル比や、複数の異なるバイタル値情報候補の信頼度情報の比較結果に基づいて生成することができる。 Reliability information is information indicating the reliability (likelihood) of vital value information. The biological information detection device 12 calculates the reliability of the calculated vital value information based on the detection information and signal information of the sensor data 20. Note that the reliability information can be generated based on the noise level ratio of the radar signal that is the calculation source of the vital value information or the comparison result of the reliability information of a plurality of different vital value information candidates.
 生体情報検出装置12は、生成した生体情報21を管理装置13及び端末装置14へ送信する。 The biological information detection device 12 transmits the generated biological information 21 to the management device 13 and the terminal device 14.

The biological level information 22 is information indicating the degree (level) of vital values of the person 1, which is the active state. At this time, the management device 13 generates living body grade information 22 based on the living body grade determination information 23. The biological grade determination information 23 includes information for determining the grade from vital values. The user can operate the management device 13 to set the biological grade determination information 23. Note that details of the biological grade determination information will be described later.
 管理装置13は、生成した生体程度情報22及び生体程度判定情報23を端末装置14へ送信する。 The management device 13 transmits the generated living body grade information 22 and living body grade determination information 23 to the terminal device 14.
 端末装置14は、生体情報検出装置12から受信した生体情報21と、管理装置13から受信した生体程度情報22及び生体程度判定情報23とに基づいて、監視エリア8における人物1の行動又は状態を推定し、監視画面に表示する。このとき、端末装置14は、表示設定情報24に基づいて、人物1の行動又は状態の表示態様を決定する。表示設定情報24は、人物の行動又は状態の表示態様の設定を含む情報である。ユーザは、端末装置14を操作して、表示設定情報24を設定できる。なお、表示設定情報24の詳細については後述する。 The terminal device 14 determines the behavior or state of the person 1 in the monitoring area 8 based on the biometric information 21 received from the biometric information detection device 12 and the biometric level information 22 and biometric level determination information 23 received from the management device 13.

 利用シーン「見守り」用の生体程度判定情報23の設定画面100Aは、図7に示すように、バイタル値の閾値設定領域101、バイタル値の時間変化度の閾値設定領域102、呼吸の深さの閾値設定領域103、測定人数設定領域104を含んで構成される。 As shown in FIG. 7, the setting screen 100A of the living body level determination information 23 for the usage scene "watching" includes a threshold setting area 101 for vital values, a threshold setting area 102 for the degree of change over time of vital values, and a setting area 102 for the depth of breathing. It is configured to include a threshold setting area 103 and a measurement number setting area 104.
 ユーザは、バイタル値の閾値設定領域101に含まれる閾値バー120を調整して、バイタル値からバイタル値の高低に関する生体程度を決定するための閾値を設定する。バイタル値の高低に関する生体程度を、バイタル高低程度と称する。例えば、バイタル高低程度として、「低」、「普通」、「高」の3段階を設定する場合、図7に示すように、ユーザは、「低」と「普通」を区別する閾値1と、「普通」と「高」を区別する閾値2とを設定する。例えば、ユーザは、見守り対象である高齢者向けに、当該閾値を低め(つまり厳しめ)に設定してもよい。設定された閾値1と閾値2は数値として表示されてよい。なお、バイタル高低程度の数は3段階に限られず、2段階でもよいし、4段階以上であってもよい。また、バイタル高低程度の各段階の名称はユーザが変更可能であってもよい。また、バイタル高低程度の各段階は、バイタル高低レベルと読み替えられてもよい。 The user adjusts the threshold bar 120 included in the vital value threshold setting area 101 to set a threshold value for determining the biological level of the vital value based on the vital value. The biological degree of the level of vital values is referred to as the degree of vital level. For example, when setting three levels of vital levels: "low," "normal," and "high," the user sets threshold 1 to distinguish between "low" and "normal," as shown in FIG. A threshold value 2 is set to distinguish between "normal" and "high". For example, the user may set the threshold to be lower (that is, stricter) for elderly people who are to be watched over. The set threshold value 1 and threshold value 2 may be displayed as numerical values. Note that the number of vital levels is not limited to three levels, and may be two levels or four or more levels. Further, the names of each stage of vital levels may be changeable by the user. In addition, each stage of the degree of vitality level may be read as a level of vitality level.
 ユーザは、バイタル値の時間変化度の閾値設定領域102に含まれる閾値バー120を調整して、バイタル値の時間変化度からバイタル値の時間変化度に関する生体程度を決定するための閾値を設定する。バイタル値の時間変化度に関する生体程度には、上昇方向の程度と、下降方向の程度とが含まれる。上昇方向の程度を、バイタル上昇変化程度と称する。下降方向の程度を、バイタル下降変化程度と称する。例えば、バイタル上昇変化程度として、「変化なし」、「上昇」、「急上昇」の3段階を設定する場合、図7に示すように、「変化なし」と「上昇」を区別する閾値1と、「上昇」と「急上昇」を区別する閾値2とを設定する。例えば、ユーザは、見守り対象である高齢者向けに、当該閾値を低め(つまり厳しめ)に設定してもよい。設定された閾値1と閾値2は数値として表示されてよい。なお、バイタル上昇変化程度の各段階は、バイタル上昇変化レベルと読み替えられてもよい。例えば、バイタル下降変化程度として、「変化なし」、「下降」、「急下降」の3段階を設定する場合、図7に示すように、「変化なし」と「下降」を区別する閾値1と、「下降」と「急下降」を区別する閾値2とを設定する。例えば、ユーザは、見守り対象である高齢者向けに、当該閾値を低め(つまり厳しめ)に設定してもよい。設定された閾値1と閾値2は数値として表示されてよい。なお、バイタル下降変化程度の各段階は、バイタル下降変化レベルと読み替えられてもよい。 The user adjusts the threshold bar 120 included in the threshold setting area 102 for the degree of change in vital values over time to set a threshold for determining the biological degree of the degree of change in vital values over time based on the degree of change in vital values over time. . The biological degree regarding the degree of change in vital values over time includes a degree in an upward direction and a degree in a downward direction. The degree in the upward direction is referred to as the degree of change in vital vitals. The degree in the downward direction is referred to as the degree of vital decline change. For example, if three levels are set as the degree of change in vitals: "no change," "increase," and "rapidly increase," as shown in FIG. A threshold value 2 is set to distinguish between "increase" and "rapid rise". For example, the user may set the threshold to be lower (that is, stricter) for elderly people who are to be watched over. The set threshold value 1 and threshold value 2 may be displayed as numerical values. Note that each stage of the degree of increase in vitals may be read as a level of increase in vitals. For example, when setting three levels of vital signs such as "no change," "declining," and "sudden decline," as shown in FIG. , and a threshold value 2 that distinguishes between "downward" and "sudden descent" is set. For example, the user may set the threshold to be lower (that is, stricter) for elderly people who are to be watched over. The set threshold value 1 and threshold value 2 may be displayed as numerical values. Note that each stage of the degree of decline in vitals may be read as a level of decline in vitals.
 ユーザは、呼吸の深さの閾値設定領域103に含まれる閾値バー120を調整して、バイタル値の呼吸の深さからバイタル値の呼吸の深さに関する生体程度を決定するための閾値を設定する。バイタル値の呼吸の深さに関する生体程度を、呼吸の深さ程度と称する。例えば、呼吸の深さ程度として「浅い」、「普通」、「深い」の3段階を設定する場合、図7に示すように、ユーザは、「浅い」と「普通」を区別する閾値1と、「普通」と「深い」を区別する閾値2とを設定する。例えば、ユーザは、見守り対象である高齢者向けに、当該閾値を低め(つまり厳しめ)に設定してもよい。設定された閾値1と閾値2は数値として表示されてよい。なお、呼吸の深さ程度の各段階は、呼吸の深さレベルと読み替えられてもよい。 The user adjusts the threshold bar 120 included in the breathing depth threshold setting area 103 to set a threshold for determining the degree of living body related to the breathing depth of the vital value from the breathing depth of the vital value. . The degree of the living body's vital values related to the depth of respiration is referred to as the degree of respiration depth. For example, when setting three levels of breathing depth: "Shallow," "Normal," and "Deep," the user sets threshold 1 to distinguish between "Shallow" and "Normal," as shown in Figure 7. , a threshold value 2 for distinguishing between "normal" and "deep" is set. For example, the user may set the threshold to be lower (that is, stricter) for elderly people who are to be watched over. The set threshold value 1 and threshold value 2 may be displayed as numerical values. Note that each stage of breathing depth may be read as a breathing depth level.
 ユーザは、測定人数設定領域104に、測定対象とする人物の最大人数を設定する。以下、設定された最大人数を、測定最大人数と称する。例えば、ユーザは、見守り対象である高齢者が、監視エリアである部屋に一人で住んでいる場合、「1人」を設定してよい。典型的に、測定最大人数を少なくした方が、生体情報の信頼度は向上する。 The user sets the maximum number of people to be measured in the measurement number setting area 104. Hereinafter, the set maximum number of people will be referred to as the maximum number of people to be measured. For example, if the elderly person to be watched lives alone in the room that is the monitoring area, the user may set "one person". Typically, the reliability of biometric information improves when the maximum number of people measured is reduced.
 管理装置13は、ユーザによって設定された各閾値及び測定最大人数を含む生体程度判定情報23を生成し、利用シーン「見守り」と対応付けてストレージ1003に保持する。これにより、管理装置13は、図5に示す監視処理において、利用シーン「見守り」が選択された場合、利用シーン「見守り」用に適切に設定された生体程度判定情報23を利用できる。 The management device 13 generates biological degree determination information 23 including each threshold value set by the user and the maximum number of people to be measured, and stores it in the storage 1003 in association with the usage scene "watching over". Thereby, in the monitoring process shown in FIG. 5, when the usage scene "watching over" is selected, the management device 13 can use the living body level determination information 23 appropriately set for the usage scene "watching over".

 図8は、実施の形態1に係る利用シーン「見守り」用の表示設定情報24の設定画面200Aを示す図である。
<Display setting information for monitoring>
FIG. 8 is a diagram showing a setting screen 200A of the display setting information 24 for the usage scene "watching" according to the first embodiment.
 利用シーン「見守り」用の表示設定情報24の設定画面200Aは、図8に示すように、項目として、行動又は状態名と、設定名と、設定値とを有する。 As shown in FIG. 8, the setting screen 200A of the display setting information 24 for the usage scene "watching" has as items an action or state name, a setting name, and a setting value.
 行動又は状態名は、人物の行動又は状態の名称を示す。 The action or state name indicates the name of the person's action or state.
 設定名は、行動又は状態名に対応付けられる設定の名称を示す。1つの行動又は状態名に、1又は複数の設定名が対応付けられる。 The setting name indicates the name of the setting associated with the action or state name. One or more setting names are associated with one action or state name.
 設定値は、設定名に対応付けられる値を示す。1つの設定名に、1つの設定値が対応付けられる。ただし、1つの設定名に、複数の設定値が対応付けられてもよい。設定名と設定値のセットを表示設定パラメータと称してもよい。 The setting value indicates the value associated with the setting name. One setting value is associated with one setting name. However, a plurality of setting values may be associated with one setting name. A set of a setting name and a setting value may be referred to as a display setting parameter.
<<就寝中>>
 例えば、図8に示すように、行動又は状態名「就寝中」に、設定名「場所条件」、「姿勢条件」、「生体程度条件」、及び、「アイコン名」が対応付けられる。
<<Sleeping>>
For example, as shown in FIG. 8, the action or state name "sleeping" is associated with setting names "location condition,""posturecondition,""living condition condition," and "icon name."
 設定名「場所条件」の設定値は、人物の行動を「就寝中」と判定するための人物の位置の範囲を示す。当該範囲は、マップにおけるX区間とY区間によって定められてよい。例えば、ユーザは、行動「就寝中」に対応付ける設定名「場所条件」の設定値として、マップ(住居の間取り図)の「寝室」の範囲を設定する。 The setting value of the setting name "location condition" indicates the range of a person's position for determining the person's behavior as "sleeping." The range may be defined by an X section and a Y section on the map. For example, the user sets the range of "bedroom" on the map (floor plan of the residence) as the setting value of the setting name "location condition" associated with the action "sleeping."
 設定名「姿勢条件」の設定値は、人物の行動を「就寝中」と判定するための人物の姿勢を示す。当該姿勢は、所定の姿勢リストから1つ選択されてよい。例えば、ユーザは、行動「就寝中」に対応付ける設定名「姿勢条件」の設定値として、所定の姿勢リストから「臥位」を選択する。 The setting value of the setting name "posture condition" indicates the posture of the person for determining the person's behavior as "sleeping". One of the postures may be selected from a predetermined posture list. For example, the user selects "supine position" from a predetermined posture list as the setting value of the setting name "posture condition" associated with the action "sleeping."
 設定名「生体程度条件」の設定値は、人物の行動を「就寝中」と判定するための人物の生体程度及び当該生体程度の補正量を示す。一般的に、就寝中の人物は、安静にしているため、バイタル値が通常よりも低くなる傾向にある。そこで、ユーザは、行動「就寝中」に対応付ける設定名「生体程度条件」の設定値として、デフォルトのバイタル高低程度の閾値を所定量低くするような補正量を設定してよい。これにより、人物が就寝中のためにバイタル値が通常よりも少し低くなっているだけであるにも関わらず、端末装置14が、バイタル高低程度を「低」と誤判定してしまう可能性を抑制できる。ただし、行動名「就寝中」に設定名「生体程度条件」を対応付けることは必須ではない。 The setting value of the setting name "biological degree condition" indicates the biological degree of the person and the correction amount of the biological degree for determining the person's behavior as "sleeping". In general, a person who is sleeping is at rest, so their vital values tend to be lower than normal. Therefore, the user may set a correction amount that lowers the default threshold of vital level level by a predetermined amount as a setting value of the setting name "biological level condition" associated with the action "sleeping". This eliminates the possibility that the terminal device 14 may erroneously determine the level of vitals as "low" even though the person's vitals are only slightly lower than normal because the person is sleeping. It can be suppressed. However, it is not essential to associate the action name "sleeping" with the setting name "living condition".
 設定名「アイコン名」の設定値は、人物の行動を「就寝中」と判定した場合に使用するアイコンのファイル名を示す。 The setting value of the setting name "icon name" indicates the file name of the icon used when the behavior of the person is determined to be "sleeping".
 例えば、端末装置14は、人物の位置が設定名「場所条件」の設定値が示す範囲内(例えば寝室内)にあり、人物の姿勢が設定名「姿勢条件」の設定値が示す姿勢「臥位」であり、人物のバイタル高低程度が設定名「生体程度条件」の設定値によって補正された「普通」である場合、当該人物の行動を「就寝中」と判定し、設定名「アイコン名」の設定値が示すファイル名のアイコンを表示する。なお、表示方法の詳細については後述する。 For example, the terminal device 14 determines that the position of the person is within the range indicated by the setting value of the setting name "location condition" (for example, in the bedroom), and the person's posture is in the position indicated by the setting value of the setting name "posture condition". If the person's vital level is "normal" corrected by the setting value of the setting name "biological condition", the person's behavior is determined to be "sleeping", and the person's behavior is determined to be "sleeping", ” Displays the icon of the file name indicated by the setting value. Note that details of the display method will be described later.
<<テレビ視聴中>>
 例えば、図8に示すように、行動及び状態名「テレビ視聴中」に、設定名「場所条件」、「姿勢条件」、「生体程度条件」、「アイコン名」が対応付けられる。
<<Watching TV>>
For example, as shown in FIG. 8, the behavior and state name "Watching TV" is associated with the setting names "location condition,""posturecondition,""living condition condition," and "icon name."
 設定名「場所条件」の設定値は、人物の行動を「テレビ視聴中」と判定するための人物の位置の範囲を示す。当該範囲は、マップにおけるX区間とY区間によって定められてよい。例えば、ユーザは、行動「テレビ視聴中」に対応付ける設定名「場所条件」の設定値として、マップ(住居の間取り図)の「リビング」の範囲を設定する。 The setting value of the setting name "location condition" indicates the range of a person's position for determining the person's behavior as "watching TV." The range may be defined by an X section and a Y section on the map. For example, the user sets the range of "living room" on the map (floor plan of the residence) as the setting value of the setting name "location condition" associated with the action "watching TV."
 設定名「姿勢条件」の設定値は、人物の行動を「テレビ視聴中」と判定するための人物の姿勢を示す。当該姿勢は、所定の姿勢リストから1つ選択されてよい。例えば、ユーザは、行動「テレビ視聴中」に対応付ける設定名「姿勢条件」の設定値として、所定の姿勢リストから「座位」を選択する。 The setting value of the setting name "posture condition" indicates the posture of the person for determining the person's behavior as "watching TV." One of the postures may be selected from a predetermined posture list. For example, the user selects "sitting position" from a predetermined posture list as the setting value of the setting name "posture condition" associated with the action "watching television."
 設定名「生体程度条件」の設定値は、人物の行動を「テレビ視聴中」と判定するための人物の生体程度及び当該生体程度の補正量を示す。例えば、テレビ視聴中の人物は、コンテンツの影響を受けて、バイタル値が通常よりも高くなる可能性がある。そこで、ユーザは、行動「テレビ視聴中」に対応付ける設定名「生体程度条件」の設定値として、デフォルトのバイタル高低程度の閾値を所定量高くするような補正量を設定してよい。これにより、人物がテレビ視聴中のためにバイタル値が通常よりも少し高くなっているにも関わらず、端末装置14が、バイタル高低程度を「高」と誤判定してしまう可能性を抑制できる。ただし、行動名「テレビ視聴中」に設定名「生体程度条件」を対応付けることは必須ではない。 The setting value of the setting name "biological degree condition" indicates the biological degree of the person and the correction amount of the biological degree for determining the person's behavior as "watching TV." For example, a person watching television may have higher vital values than normal due to the influence of the content. Therefore, the user may set a correction amount that increases the default threshold of vital level level by a predetermined amount as a setting value of the setting name "biological level condition" associated with the action "watching television". As a result, it is possible to suppress the possibility that the terminal device 14 will erroneously judge the level of vitals as "high" even though the person's vitals are a little higher than usual because the person is watching TV. . However, it is not essential to associate the action name "Watching TV" with the setting name "Biological degree condition".
 設定名「アイコン名」の設定値は、人物の行動を「テレビ視聴中」と判定した場合に使用するアイコンのファイル名を示す。 The setting value of the setting name "icon name" indicates the file name of the icon used when the person's behavior is determined to be "watching TV."
 例えば、端末装置14は、人物の位置が「場所条件」の設定値が示す範囲内(例えばリビング内)であり、人物の姿勢が「姿勢条件」の設定値が示す姿勢「座位」であり、人物のバイタル高低程度が設定名「生体程度条件」の設定値によって補正された「普通」である場合、当該人物の行動を「テレビ視聴中」と判定し、「アイコン名」の設定値が示すファイル名のアイコンを表示する。なお、表示方法の詳細については後述する。 For example, the terminal device 14 determines that the position of the person is within the range indicated by the setting value of "location condition" (for example, in the living room), the posture of the person is "sitting", which is indicated by the setting value of "posture condition", If the person's vital level is "normal" as corrected by the setting value of the setting name "biological condition", the person's behavior is determined to be "watching TV" and the setting value of "icon name" indicates. Show file name icon. Note that details of the display method will be described later.
<<異常状態>>
 例えば、図8に示すように、行動又は状態名「異常状態」に、設定名「場所条件」、「姿勢条件」、「バイタル高低程度条件」、「バイタル上昇/下降変化程度条件」、「アイコン名」が対応付けられる。
<<Abnormal condition>>
For example, as shown in FIG. 8, the action or state name "abnormal state" is replaced with the setting names "place condition", "posture condition", "vital height condition", "vital rise/decrease change degree condition", and "icon". "first name" is associated.
 設定名「場所条件」の設定値は、人物の状態を「異常状態」と判定するための人物の位置の範囲を示す。図8では、監視エリア8の全範囲を当該異常状態の判定の範囲に設定している。 The setting value of the setting name "location condition" indicates the range of the position of the person for determining the state of the person as "abnormal state". In FIG. 8, the entire range of the monitoring area 8 is set as the range for determining the abnormal state.
 設定名「姿勢条件」の設定値は、人物の状態を「異常状態」と判定するための人物の姿勢を示す。当該姿勢は、所定の姿勢リストから1つ選択されてよい。例えば、ユーザは、状態「異常状態」に対応付ける設定名「姿勢条件」の設定値として、所定の姿勢リストから「臥位」を選択する。 The setting value of the setting name "posture condition" indicates the posture of the person for determining the state of the person as "abnormal state." One of the postures may be selected from a predetermined posture list. For example, the user selects "supine position" from a predetermined posture list as the setting value of the setting name "posture condition" associated with the state "abnormal state."
 設定名「バイタル高低程度条件」の設定値は、人物の状態を「異常状態」と判定するためのバイタル高低程度を示す。例えば、ユーザは、状態「異常状態」に対応付ける設定名「バイタル高低程度条件」の設定値として、「高」と「低」を設定する。 The setting value of the setting name "vital height level condition" indicates the level of vitality level for determining a person's condition as an "abnormal state". For example, the user sets "high" and "low" as the setting values of the setting name "vital height level condition" associated with the state "abnormal state".
 設定名「バイタル上昇/下降変化程度条件」の設定値は、人物の状態を「異常状態」と判定するためのバイタル上昇変化程度及びバイタル下降変化程度を示す。例えば、ユーザは、状態「異常状態」に対応付ける設定名「バイタル上昇/下降変化程度条件」の設定値として、「急上昇」と「急降下」を設定する。 The setting value with the setting name "Vital rising/falling change degree condition" indicates the degree of vital rise change and the degree of vital decrease change for determining the person's condition as an "abnormal state." For example, the user sets "sudden rise" and "sudden fall" as setting values for the setting name "vital rise/fall change degree condition" associated with the state "abnormal state".
 設定名「アイコン名」の設定値は、人物の状態を「異常状態」と判定した場合に使用するアイコンのファイル名を示す。 The setting value of the setting name "icon name" indicates the file name of the icon to be used when the state of the person is determined to be "abnormal state".
 例えば、端末装置14は、人物の位置が監視エリア8のいずれか(例えば住居のいずれか)であり、人物の姿勢が「姿勢条件」の設定値が示す姿勢「臥位」であり、人物のバイタル高低程度が「バイタル高低程度条件」の設定値が示す「高」又は「低」であり、人物のバイタル上昇変化程度又はバイタル下降変化程度が「バイタル上昇/下降変化程度条件」の設定値が示す「急上昇」又は「急下降」である場合、当該人物の状態を「異常状態」と判定し、設定名「アイコン名」の設定値が示すファイル名のアイコンを表示する。なお、表示方法の詳細については後述する。 For example, the terminal device 14 determines that the person's position is in any of the monitoring areas 8 (for example, in a residence), the person's posture is the “supine position” indicated by the setting value of “posture condition”, and the person's The level of vitals is "high" or "low" as indicated by the setting value of "Vital height/lower level condition", and the degree of increase or decrease of vitals of the person is indicated by the setting value of "Vital increase/lower change level condition". In the case of "sudden rise" or "sudden fall", the state of the person is determined to be "abnormal", and an icon with the file name indicated by the setting value of the setting name "icon name" is displayed. Note that details of the display method will be described later.

<Biological degree correction setting information for monitoring>
FIG. 9 is a diagram illustrating a setting screen 300A of biological degree correction setting information for the usage scene "watching" according to the first embodiment.
 端末装置14は、上述した表示設定情報24に加えて、図9に示す生体程度補正設定情報を設定するための設定画面300Aを表示する。 In addition to the display setting information 24 described above, the terminal device 14 displays a setting screen 300A for setting biological degree correction setting information shown in FIG.
 生体程度補正設定情報の設定画面300Aは、項目として、場所名と、補正量とを有する。場所名は、監視エリア8の場所の名称を示す。監視エリア8が住居である場合、場所名は、例えば、「リビング」、「トイレ」、「浴室」、「寝室」等である。補正量は、人物が、場所名が示す場所に位置する場合における、生体程度判定情報23の補正量を示す。 The setting screen 300A of biological degree correction setting information has a place name and a correction amount as items. The place name indicates the name of the place in the monitoring area 8. When the monitoring area 8 is a residence, the place name is, for example, "living room", "toilet", "bathroom", "bedroom", etc. The amount of correction indicates the amount of correction of the living body degree determination information 23 when the person is located at the location indicated by the place name.
 例えば、図9に示す生体程度補正設定情報の1行目に示すように、ユーザは、場所名「トイレ」に対して、補正量として、バイタル高低程度の「高」の閾値を高くする設定を対応付けてよい。この場合、端末装置14は、トイレに位置する人物については、当該補正量を考慮してバイタル高低程度を判定する。これにより、人物がトレイ中のためにバイタル値が通常よりも少し高くなっているだけであるにも関わらず、バイタル高低程度を「高」と誤判定してしまう可能性を抑制できる。 For example, as shown in the first line of the biological degree correction setting information shown in FIG. May be associated. In this case, the terminal device 14 determines the level of vitals of a person located in the toilet, taking into consideration the correction amount. This can suppress the possibility of erroneously determining the level of vitals as "high" even though the person's vitals are only slightly higher than normal because the person is in the tray.
 例えば、図9に示す生体程度補正設定情報の2行目に示すように、ユーザは、場所名「浴室」に対して、補正量として、バイタル高低程度の「高」の閾値を高くする設定を対応付けてよい。この場合、端末装置14は、浴室に位置する人物については、当該補正量を考慮してバイタル高低程度を判定する。これにより、端末装置14は、人物が入浴中のためにバイタル値が通常よりも少し高くなっているにも関わらず、バイタル高低程度を「高」と誤判定してしまう可能性を抑制できる。 For example, as shown in the second line of the biological degree correction setting information shown in FIG. May be associated. In this case, the terminal device 14 determines the level of vitals of a person located in the bathroom, taking into consideration the correction amount. Thereby, the terminal device 14 can suppress the possibility of erroneously determining the level of the vitals as "high" even though the vitals are slightly higher than usual because the person is taking a bath.

 端末装置14は、生体情報検出装置12から受信した生体情報21に基づいて、人物1の位置を検出する。端末装置14は、検出した人物の位置を間取り図にマッピングし、人物1の場所名を特定する。端末装置14は、特定した場所名を、場所領域403に表示する。 The terminal device 14 detects the position of the person 1 based on the biometric information 21 received from the biometric information detection device 12. The terminal device 14 maps the detected position of the person on the floor plan and identifies the place name of the person 1. The terminal device 14 displays the specified place name in the place area 403.
 端末装置14は、生体情報検出装置12から受信した生体情報21と、管理装置13から受信した生体程度情報22と、表示設定情報24とに基づいて、人物1の行動を推定する。端末装置14は、推定した人物1の行動名を、行動領域404に表示する。 The terminal device 14 estimates the behavior of the person 1 based on the biometric information 21 received from the biometric information detection device 12, the biometric information 22 received from the management device 13, and the display setting information 24. The terminal device 14 displays the estimated action name of the person 1 in the action area 404.
 また、端末装置14は、マップ領域401の上記特定した場所に、上記推定した行動に対応するアイコン500と、生体程度に対応するアイコン501とを表示する。なお、本実施の形態におけるアイコンは、図形情報と読み替えられてよい。 Further, the terminal device 14 displays an icon 500 corresponding to the estimated behavior and an icon 501 corresponding to a living body at the specified location in the map area 401. Note that the icon in this embodiment may be read as graphic information.
 例えば、端末装置14は、生体情報21から推定した人物1の姿勢が「臥位」である場合、姿勢領域402に「臥位」を表示する。 For example, if the posture of the person 1 estimated from the biometric information 21 is “supine”, the terminal device 14 displays “supine” in the posture area 402.

<利用シーン:異常検知>
 次に、検出システム10の利用シーンの一例である、オフィスで働く従業員の生体の異常検知について説明する。
<Usage scene: Anomaly detection>
Next, a description will be given of detection of abnormalities in the living body of an employee working in an office, which is an example of a usage scene of the detection system 10.
 図13は、実施の形態1に係る利用シーン「異常検知」の選択画面50Bを示す図である。 FIG. 13 is a diagram showing a selection screen 50B for the usage scene "abnormality detection" according to the first embodiment.
 管理装置13は、図4のステップS11において、図13に示す利用シーンの選択画面50Bを表示する。ユーザが、利用シーンとして「異常検知」を選択すると、管理装置13は、次に示す、利用シーン「異常検知」用の生体程度判定情報23の設定画面100Bを表示する。 In step S11 of FIG. 4, the management device 13 displays the usage scene selection screen 50B shown in FIG. 13. When the user selects "abnormality detection" as the usage scene, the management device 13 displays a setting screen 100B of biological grade determination information 23 for the usage scene "abnormality detection" as shown below.
<異常検知用の設定画面>
 図14は、実施の形態1に係る利用シーン「異常検知」用の生体程度判定情報23の設定画面100Bの一例を示す図である。
<Settings screen for abnormality detection>
FIG. 14 is a diagram illustrating an example of a setting screen 100B for the biological grade determination information 23 for the usage scene "abnormality detection" according to the first embodiment.
 利用シーン「異常検知」用の生体程度判定情報23の設定画面100Bは、図14に示すように、バイタル値の閾値設定領域101、バイタル値の時間変化度の閾値設定領域102、信頼度の閾値設定領域105、測定人数設定領域104を含んで構成される。 As shown in FIG. 14, the setting screen 100B of the living body grade determination information 23 for the usage scene "abnormality detection" includes a threshold setting area 101 for vital values, a threshold setting area 102 for the degree of change over time of vital values, and a threshold for reliability. It is configured to include a setting area 105 and a measurement number setting area 104.
 ユーザは、上述した図7と同様に、バイタル値の閾値設定領域101の閾値バー120を調整して、バイタル高低程度の閾値を設定する。例えば、ユーザは、異常検知対象である従業員は比較的健康であるため、当該閾値を高め(つまり緩め)に設定してもよい。 Similarly to FIG. 7 described above, the user adjusts the threshold bar 120 in the vital value threshold setting area 101 to set a threshold value corresponding to the height of the vital value. For example, the user may set the threshold to be high (ie, relaxed) because the employee who is the target of abnormality detection is relatively healthy.
 ユーザは、上述した図7と同様に、バイタル値の時間変化度の閾値設定領域102の閾値バー120を調整して、バイタル上昇変化程度及びバイタル下降変化程度の閾値を設定する。例えば、ユーザは、異常検知対象である従業員は比較的健康であるものの、バイタルの急激な変化を見逃したくないので、当該閾値を低め(つまり厳しめ)に設定してもよい。 Similarly to FIG. 7 described above, the user adjusts the threshold bar 120 in the threshold value setting area 102 for the degree of change over time of vital values to set the threshold values for the degree of increase in vital values and the degree of decrease in vital values. For example, although the employee who is the target of abnormality detection is relatively healthy, the user does not want to overlook a sudden change in vital signs, so the user may set the threshold to be low (ie, strict).
 ユーザは、信頼度の閾値設定領域105に含まれる閾値バー120を調整して、生体情報21に含まれる信頼度情報から信頼度の高低に関する生体程度を決定するための閾値を決定する。信頼度の高低に関する生体程度を、信頼程度と称する。例えば、信頼程度として、「低」、「普通」、「高」の3段階を設定する場合、図14に示すように、ユーザは、「低」と「普通」を区別する閾値1と、「普通」と「高」を区別する閾値2とを設定する。例えば、ユーザは、オフィスのような環境で、異常状態でないにも関わらず、異常状態であるという誤検出が頻繁に発生すると運用に支障が出るので、当該閾値を高め(つまり厳しめ)に設定してもよい。設定された閾値1と閾値2は数値として表示されてよい。なお、信頼程度の数は3段階に限られず、2段階でもよいし、4段階以上であってもよい。また、信頼程度の各段階は、信頼レベルと読み替えられてもよい。 The user adjusts the threshold bar 120 included in the reliability threshold setting area 105 to determine the threshold for determining the biological degree of reliability based on the reliability information included in the biometric information 21. The biological level regarding the level of reliability is referred to as the level of trust. For example, when setting three levels of confidence: "low," "normal," and "high," the user sets threshold 1 to distinguish between "low" and "normal," as shown in FIG. A threshold value 2 for distinguishing between "normal" and "high" is set. For example, in an environment such as an office, a user may set the threshold to be high (that is, to be strict) because frequent false detections of an abnormal state even though the state is not present will hinder operations. You may. The set threshold value 1 and threshold value 2 may be displayed as numerical values. Note that the number of confidence levels is not limited to three levels, and may be two levels or four or more levels. Furthermore, each level of trust may be read as a trust level.
 ユーザは、上述した図7と同様に、測定人数設定領域104に、測定最大人数を設定する。例えば、ユーザは、オフィスに勤務する従業員の数に合わせて、測定最大人数を設定してもよい。 Similarly to FIG. 7 described above, the user sets the maximum number of people to be measured in the number of people to be measured setting area 104. For example, the user may set the maximum number of people to be measured according to the number of employees working in the office.
 管理装置13は、ユーザによって設定された各閾値及び測定最大人数を含む生体程度判定情報23を生成し、利用シーン「異常検知」と対応付けてストレージ1003に保持する。これにより、管理装置13は、図5に示す監視処理において、利用シーン「異常検知」が選択された場合、「異常検知」用に適切に設定された生体程度判定情報23を利用できる。 The management device 13 generates biological degree determination information 23 including each threshold value set by the user and the maximum number of people to be measured, and stores it in the storage 1003 in association with the usage scene "abnormality detection". Thereby, in the monitoring process shown in FIG. 5, when the usage scene "abnormality detection" is selected, the management device 13 can use the biological degree determination information 23 appropriately set for "abnormality detection".
<異常検知用の表示設定情報>
 図15は、実施の形態1に係る利用シーン「異常検知」用の表示設定情報24の設定画面を示す図である。
<Display setting information for abnormality detection>
FIG. 15 is a diagram showing a setting screen of the display setting information 24 for the usage scene "abnormality detection" according to the first embodiment.
 利用シーン「異常検知」用の表示設定情報24の設定画面は、図15に示すように、図8と同様、項目として、行動又は状態名と、設定名と、設定値とを有する。 As shown in FIG. 15, the setting screen of the display setting information 24 for the usage scene "abnormality detection" has, as shown in FIG. 8, an action or state name, a setting name, and a setting value as items.
<<作業中>>
 例えば、図15に示すように、行動又は状態名「作業中」に、設定名「場所条件」、「姿勢条件」、「生体程度条件」、「アイコン名」が対応付けられる。
<<Work in progress>>
For example, as shown in FIG. 15, the action or state name "working" is associated with the setting names "location condition,""posturecondition,""living condition condition," and "icon name."
 設定名「場所条件」の設定値は、人物の行動を「作業中」と判定するための人物の位置の範囲を示す。当該範囲は、マップにおけるX区間とY区間によって定められてよい。例えば、ユーザは、行動「作業中」に対応付ける設定名「場所条件」の設定値として、マップ(例えばオフィスの見取り図)の「デスク」の範囲を設定する。 The setting value of the setting name "location condition" indicates the range of a person's position for determining the person's behavior as "working". The range may be defined by an X section and a Y section on the map. For example, the user sets the range of "desk" on a map (for example, a floor plan of an office) as a setting value of the setting name "location condition" associated with the action "working".
 設定名「姿勢条件」の設定値は、人物の行動を「作業中」と判定するための人物の姿勢を示す。当該姿勢は、所定の姿勢リストから1つ選択されてよい。例えば、ユーザは、行動「作業中」に対応付ける設定名「姿勢条件」の設定値として、所定の姿勢リストから「座位」を選択する。 The setting value of the setting name "posture condition" indicates the posture of the person for determining the person's behavior as "working". One of the postures may be selected from a predetermined posture list. For example, the user selects "sitting position" from a predetermined posture list as the setting value of the setting name "posture condition" associated with the action "working".
 設定名「生体程度条件」の設定値は、人物の行動を「作業中」と判定するための人物の生体程度及び当該生体程度の補正量を示す。一般的に、作業中の人物は、集中しているため、バイタル値が通常よりも低くなる傾向にある。そこで、ユーザは、行動「作業中」に対応付ける設定名「生体程度条件」の設定値として、デフォルトのバイタル高低程度の閾値を所定量低くするような補正量を設定してよい。これにより、人物が作業中のためにバイタル値が通常よりも少し低くなっているだけであるにも関わらず、管理装置13が、バイタル高低程度を「低」と誤判定してしまう可能性を抑制できる。ただし、行動名「作業中」に設定名「生体程度条件」を対応付けることは必須ではない。 The setting value of the setting name "living condition" indicates the living body level of the person and the correction amount of the living body level for determining the person's behavior as "working". Generally, a person working is concentrating, so their vital values tend to be lower than normal. Therefore, the user may set a correction amount that lowers the default threshold of vital level level by a predetermined amount as a setting value of the setting name "biological level condition" associated with the action "working". This eliminates the possibility that the management device 13 may incorrectly determine the level of vitals as "low" even though the person's vitals are only slightly lower than normal because the person is working. It can be suppressed. However, it is not essential to associate the action name "Working" with the setting name "Living condition".
 設定名「アイコン名」の設定値は、人物の行動を「作業中」と判定した場合に使用するアイコンのファイル名を示す。 The setting value of the setting name "icon name" indicates the file name of the icon used when the person's behavior is determined to be "working".
 端末装置14は、人物の位置が「場所条件」の設定値が示す範囲内(例えばデスク)であり、人物の姿勢が「姿勢条件」の設定値が示す姿勢「座位」であり、人物のバイタル高低程度が設定名「生体程度条件」の設定値によって補正された「普通」である場合、当該人物の行動を「作業中」と判定し、設定名「アイコン名」の設定値が示すファイル名のアイコンを表示する。なお、表示方法の詳細については後述する。 The terminal device 14 determines that the person's position is within the range indicated by the setting value of "place condition" (for example, at a desk), the person's posture is "sitting position" indicated by the setting value of "posture condition", and the person's vitals are If the height level is "normal" corrected by the setting value of the setting name "Biological level condition", the behavior of the person is determined to be "working" and the file name indicated by the setting value of the setting name "icon name" Display the icon. Note that details of the display method will be described later.
<<異常状態>>
 例えば、図15に示すように、行動又は状態名「異常状態」に、設定名「場所条件」、「姿勢条件」、「バイタル高低程度条件」、「バイタル上昇/下降変化程度条件」、「信頼程度条件」、「アイコン名」が対応付けられる。
<<Abnormal condition>>
For example, as shown in FIG. 15, the behavior or state name "abnormal state" is replaced with the setting names "place condition", "posture condition", "vital height condition", "vital rise/decrease change degree condition", and "confidence condition". "degree condition" and "icon name" are associated with each other.
 設定名「場所条件」、「姿勢条件」、「バイタル高低程度条件」、「バイタル上昇/下降変化程度条件」、「アイコン名」については、図8と同様であるので、説明を省略する。 The setting names "place condition", "posture condition", "vital height condition", "vital rising/falling change degree condition", and "icon name" are the same as those in FIG. 8, so their explanation will be omitted.
 設定名「信頼程度条件」の設定値は、人物1の状態を「異常状態」と判定するための信頼程度を示す。例えば、ユーザは、状態「異常状態」に対応付ける設定名「信頼程度条件」の設定値として、「高」を設定する。オフィスのような比較的健康な人物が大勢勤務するような所では、高齢者と比較して生体の異常が発生する可能性が低く、また、低い信頼程度で誤検出が頻出して運用に支障が出る可能性があるためである。 The setting value of the setting name "reliability level condition" indicates the reliability level for determining the state of person 1 as an "abnormal state". For example, the user sets "high" as the setting value of the setting name "reliability level condition" associated with the state "abnormal state". In places where many relatively healthy people work, such as offices, the possibility of biological abnormalities occurring is lower than that of elderly people, and false positives frequently occur with low reliability, hindering operations. This is because there is a possibility that
 例えば、端末装置14は、人物1の位置が「場所条件」の設定値が示す範囲内であり、人物1の姿勢が「姿勢条件」の設定値が示す姿勢「臥位」であり、人物のバイタル高低程度が「バイタル高低程度条件」の設定値が示す「高」又は「低」であり、人物1のバイタル上昇変化程度又はバイタル下降変化程度が「バイタル上昇/下降変化程度条件」の設定値が示す「急上昇」又は「急下降」であり、人物1の信頼程度が「信頼程度条件」の設定値が示す「高」である場合、当該人物1の状態を「異常状態」と判定し、設定名「アイコン名」の設定値が示すファイル名のアイコンを表示する。なお、表示方法の詳細については後述する。 For example, the terminal device 14 determines that the position of person 1 is within the range indicated by the setting value of "location condition", the posture of person 1 is the "supine position" indicated by the setting value of "posture condition", and The level of vitals is "high" or "low" as indicated by the set value of "vital height/lower level condition", and the degree of increase or decrease in vitals of person 1 is the set value of "vital increase/lower change level condition" is a "sudden rise" or "sudden decline" and the trust level of the person 1 is "high" as indicated by the setting value of the "trust level condition", the state of the person 1 is determined to be an "abnormal state", Displays the icon with the file name indicated by the setting value of the setting name "icon name". Note that details of the display method will be described later.
<異常検知用の生体程度補正設定情報>
 図16は、実施の形態1に係る利用シーン「異常検知」用の生体程度補正設定情報の設定画面を示す図である。
<Biological degree correction setting information for abnormality detection>
FIG. 16 is a diagram showing a setting screen of biological degree correction setting information for the usage scene "abnormality detection" according to the first embodiment.
 端末装置14は、上述した表示設定情報24に加えて、図16に示す生体程度補正設定情報を設定するための設定画面300Bを表示する。 In addition to the display setting information 24 described above, the terminal device 14 displays a setting screen 300B for setting biological degree correction setting information shown in FIG. 16.
 生体程度補正設定情報の設定画面300Bは、項目として、場所名と、補正量とを有する。監視エリア8がオフィスである場合、場所名は、例えば、「トイレ」、「通路」等であってよい。 The setting screen 300B for biological degree correction setting information has a place name and a correction amount as items. When the monitoring area 8 is an office, the place name may be, for example, "toilet", "aisle", etc.
 例えば、図15に示す生体程度補正設定情報の1行目に示すように、ユーザは、場所名「トイレ」に対して、補正量として、バイタル高低程度の「高」の閾値を高くする設定を対応付けてよい。この場合、端末装置14は、トイレに位置する人物1については、当該補正量を考慮してバイタル高低程度を判定する。これにより、人物1がトレイ中のためにバイタル値が通常よりも少し高くなっているにも関わらず、バイタル高低程度を「高」と誤判定してしまう可能性を抑制できる。 For example, as shown in the first line of the biological degree correction setting information shown in FIG. May be associated. In this case, the terminal device 14 determines the level of vitals of the person 1 located in the toilet, taking into consideration the correction amount. Thereby, it is possible to suppress the possibility of erroneously determining the level of vitals as "high" even though the vitals are slightly higher than usual because the person 1 is in the tray.
 例えば、図16に示す生体程度補正設定情報の2行目に示すように、ユーザは、場所名「通路」に対して、補正量として、バイタル高低程度の「高」の閾値を高くする設定を対応付けてよい。この場合、端末装置14は、通路に位置する人物1については、当該補正量を考慮してバイタル高低程度を判定する。これにより、人物が通路を移動中のためにバイタル値が通常よりも少し高くなっているだけにあるにも関わらず、端末装置14が、バイタル高低程度を「高」と誤判定してしまう可能性を抑制できる。 For example, as shown in the second line of the biological degree correction setting information shown in FIG. May be associated. In this case, the terminal device 14 determines the level of vitals of the person 1 located in the passage, taking into consideration the correction amount. As a result, the terminal device 14 may erroneously determine the level of the person's vitals as "high" even though the vitals are only slightly higher than normal because the person is moving through the aisle. You can suppress your sexuality.

 図17は、実施の形態1に係る2人の人物がオフィスにいる場合の監視画面400Dの一例を示す図である。
<Monitoring screen for abnormality detection>
FIG. 17 is a diagram illustrating an example of a monitoring screen 400D when two people are in an office according to the first embodiment.
 端末装置14は、図17に示すように、監視画面400Dを表示する。監視画面400Dは、マップ領域401を含んで構成される。 The terminal device 14 displays a monitoring screen 400D, as shown in FIG. 17. The monitoring screen 400D includes a map area 401.
 端末装置14は、マップ領域401に、マップの一例として、監視エリア8であるオフィスの見取り図を表示する。 The terminal device 14 displays a floor plan of the office, which is the monitoring area 8, as an example of a map in the map area 401.
 例えば、端末装置14は、表示設定情報24から人物Aの行動が「作業中」であると推定した場合、マップ領域401に表示されている見取り図の人物Aの位置に、「作業中」のアイコン511を表示する。加えて、端末装置14は、当該アイコン511を、信頼程度「高」であることがわかるように、例えば実線で表示する。加えて、端末装置14は、当該アイコン511の近傍に、バイタル(心拍数)上昇/下降変化程度が「普通」であることを示す矢印アイコン(図17では横向き矢印のアイコン512)を表示する。 For example, if the terminal device 14 estimates that the behavior of person A is "working" from the display setting information 24, the terminal device 14 places an icon "working" at the location of person A in the floor plan displayed in the map area 401. 511 is displayed. In addition, the terminal device 14 displays the icon 511 with, for example, a solid line so that it can be seen that the reliability level is "high". In addition, the terminal device 14 displays an arrow icon (horizontal arrow icon 512 in FIG. 17) indicating that the degree of increase/decrease in vitals (heart rate) is "normal" near the icon 511.
 例えば、端末装置14は、表示設定情報24から人物Bの行動が「移動中」であると推定した場合、マップ領域401に表示されている見取り図の人物Bの位置に、「移動中」を示すアイコン513を表示する。加えて、端末装置14は、当該アイコン513を、信頼程度「低」であることがわかるように、例えば破線で表示する。加えて、端末装置14は、当該アイコン513の近傍に、バイタル(心拍数)上昇/下降変化程度が「急上昇」であることを示す矢印アイコン(図17では斜め上向き矢印のアイコン514)を表示する。 For example, when the terminal device 14 estimates that the behavior of person B is "moving" from the display setting information 24, the terminal device 14 indicates "moving" at the position of person B in the floor plan displayed in the map area 401. An icon 513 is displayed. In addition, the terminal device 14 displays the icon 513 with, for example, a broken line so that it can be seen that the reliability level is "low". In addition, the terminal device 14 displays, near the icon 513, an arrow icon (in FIG. 17, a diagonally upward arrow icon 514) indicating that the degree of increase/decrease in vital signs (heart rate) is "rapidly". .
 これにより、ユーザは、監視画面400Dを見て、オフィスに勤務している人物Aは作業中であり、バイタルは正常であり、当該バイタルの信頼度は高いことを直感的に確認できる。また、ユーザは、監視画面400Dを見て、人物Bは移動中であり、バイタルの変化が急上昇であるものの、当該バイタルの信頼度は低いことを直感的に確認できる。 Thereby, the user can intuitively confirm by looking at the monitoring screen 400D that Person A working in the office is working, his vitals are normal, and the reliability of the vitals is high. Further, the user can intuitively confirm by looking at the monitoring screen 400D that although Person B is moving and the change in vitals is rapidly increasing, the reliability of the vitals is low.
 図18は、実施の形態1に係るオフィスに異常状態の人物がいる場合の監視画面400Eの一例を示す図である。 FIG. 18 is a diagram showing an example of the monitoring screen 400E when there is a person in an abnormal state in the office according to the first embodiment.
 例えば、端末装置14は、表示設定情報24から人物Cの状態が「異常状態」であると推定した場合、マップ領域401に表示されている見取り図の人物の位置に、「異常状態」を示すアイコン515を表示する。加えて、端末装置14は、当該アイコン515を、信頼程度「高」であることがわかるように、例えば実線で表示する。加えて、端末装置14は、当該アイコン515の近傍に、バイタルが「異常状態」であることを示すアイコン516を表示する。 For example, if the terminal device 14 estimates that the state of person C is in an "abnormal state" based on the display setting information 24, the terminal device 14 places an icon indicating "abnormal state" at the position of the person in the floor plan displayed in the map area 401. 515 is displayed. In addition, the terminal device 14 displays the icon 515 as a solid line, for example, so that it can be seen that the reliability level is "high". In addition, the terminal device 14 displays an icon 516 near the icon 515 indicating that the vitals are in an "abnormal state."
 これにより、ユーザは、監視画面400Eを見て、オフィスに勤務している人物Cにバイタル異常が発生しており、当該バイタルの信頼度は高いことを直感的に確認できる。なお、この場合、端末装置14は、生体異常の人物1が発生したことを示すアラート(例えば安否確認に関する文字列の表示や音声の発報)を出力してもよい。 As a result, the user can intuitively confirm by looking at the monitoring screen 400E that an abnormality has occurred in the vitals of the person C working in the office and that the reliability of the vitals is high. In this case, the terminal device 14 may output an alert indicating that the person 1 with a biological abnormality has occurred (for example, displaying a character string or issuing a sound regarding safety confirmation).
<利用シーン:コンテンツ視聴反応検出>
 次に、検出システム10の利用シーンの一例である、コンテンツ視聴反応検出について説明する。なお、実施の形態2では、実施の形態1にて説明済みの構成要素については共通の参照番号を付し、説明を省略する場合がある。
<Usage scene: Content viewing reaction detection>
Next, content viewing reaction detection, which is an example of a usage scene of the detection system 10, will be described. In addition, in the second embodiment, common reference numbers are given to components already explained in the first embodiment, and the explanation may be omitted.
<システム構成>
 図19は、実施の形態1に係るコンテンツ視聴反応検出における検出システム10の構成例を示す図である。
<System configuration>
FIG. 19 is a diagram showing a configuration example of the detection system 10 for content viewing reaction detection according to the first embodiment.
 検出システム10は、図1に示す構成要素に加え、コンテンツを表示するサイネージ15をさらに備える。サイネージ15は、いわゆるデジタルサイネージ装置であり、例えば液晶ディスプレイを含んで構成される。また、サイネージ15は、所定の通信ネットワークを通じて端末装置14に接続されてよい。端末装置14は、サイネージ15に表示するコンテンツを制御できてよい。 In addition to the components shown in FIG. 1, the detection system 10 further includes a signage 15 that displays content. The signage 15 is a so-called digital signage device, and includes, for example, a liquid crystal display. Further, the signage 15 may be connected to the terminal device 14 through a predetermined communication network. The terminal device 14 may be able to control content displayed on the signage 15.
 センサ11は、例えば、サイネージ15の裏面に取り付けられ、サイネージ15の前に存在する人物をセンシングする。ただし、センサ11は、どのように配置されてもよいし、複数配置されてもよい。 The sensor 11 is attached to the back surface of the signage 15, for example, and senses a person present in front of the signage 15. However, the sensors 11 may be arranged in any manner, and a plurality of sensors 11 may be arranged.
 図20は、実施の形態1に係る利用シーン「コンテンツ視聴反応検出」の選択画面50Cを示す図である。 FIG. 20 is a diagram showing a selection screen 50C of the usage scene "content viewing reaction detection" according to the first embodiment.
 管理装置13は、図4のステップS11において、図20に示す利用シーンの選択画面50Cを表示する。ユーザが、利用シーン「コンテンツ視聴反応検出」を選択すると、管理装置13は、次に示す、利用シーン「コンテンツ視聴反応検出」用の生体程度判定情報23の設定画面100Cを表示する。 In step S11 of FIG. 4, the management device 13 displays the usage scene selection screen 50C shown in FIG. 20. When the user selects the usage scene "content viewing reaction detection", the management device 13 displays a setting screen 100C of living body degree determination information 23 for the usage scene "content viewing reaction detection" shown below.
<コンテンツ視聴反応検出用の設定画面>
 図21は、実施の形態1に係る利用シーン「コンテンツ視聴反応検出」用の生体程度判定情報23の設定画面100Cの一例を示す図である。
<Settings screen for content viewing reaction detection>
FIG. 21 is a diagram illustrating an example of the setting screen 100C of the biological grade determination information 23 for the usage scene "content viewing reaction detection" according to the first embodiment.
 利用シーン「コンテンツ視聴反応検出」用の生体程度判定情報23の設定画面100Cは、図21に示すように、監視エリア設定領域106、興奮度の閾値設定領域107、信頼度の閾値設定領域105、及び、測定人数設定領域104を含んで構成される。 As shown in FIG. 21, the setting screen 100C of the living body level determination information 23 for the usage scene "content viewing reaction detection" includes a monitoring area setting area 106, an excitement level threshold setting area 107, a reliability threshold setting area 105, It also includes a measurement number setting area 104.
 ユーザは、監視エリア設定領域106に、コンテンツ視聴反応検出の監視エリア8を設定する。例えば、ユーザは、サイネージ15の前が監視エリア8となるように、X区間、Y区間、及び、Z区間を設定する。また、ユーザは、サイネージ15のサイズに応じて監視エリア8を設定してよい。 The user sets the monitoring area 8 for content viewing reaction detection in the monitoring area setting area 106. For example, the user sets the X section, Y section, and Z section so that the monitoring area 8 is in front of the signage 15. Further, the user may set the monitoring area 8 according to the size of the signage 15.
 ユーザは、興奮度の閾値設定領域107に含まれる閾値バー120を調整して、興奮度から興奮度の高低に関する生体程度を決定するための閾値を決定する。興奮度の高低に関する生体程度を、興奮程度と称する。興奮度は、バイタル値(例えば心拍数及び/又は呼吸数)の大きさと時間変化に基づいて算出されてよい。例えば、興奮程度として、「無関心」、「関心あり」、「興奮」の3段階を設定する場合、図21に示すように、ユーザは、「無関心」と「関心あり」を区別する閾値1と、「関心あり」と「興奮」を区別する閾値2とを設定する。例えば、ユーザは、人物1の多少の関心も検出できるように、当該閾値を低め(つまり緩め)に設定してもよい。設定された閾値1と閾値2は数値として表示されてよい。なお、興奮程度の数は3段階に限られず、2段階でもよいし、4段階以上であってもよい。また、興奮程度の各段階の名称はユーザが変更可能であってもよい。なお、興奮程度の各段階は、興奮レベルと読み替えられてもよい。 The user adjusts the threshold bar 120 included in the threshold setting area 107 for the degree of excitement to determine the threshold for determining the biological degree of the level of excitement based on the degree of excitement. The degree of a living organism's degree of excitement is referred to as the degree of excitement. The degree of excitement may be calculated based on the magnitude and time change of vital values (for example, heart rate and/or respiratory rate). For example, when setting three levels of excitement: "indifferent," "interested," and "excited," the user sets threshold 1 to distinguish between "indifferent" and "interested," as shown in FIG. , a threshold value 2 is set to distinguish between "interested" and "excited." For example, the user may set the threshold to be low (that is, relaxed) so that even some degree of interest of the person 1 can be detected. The set threshold value 1 and threshold value 2 may be displayed as numerical values. Note that the number of levels of excitement is not limited to three levels, but may be two levels or four or more levels. Further, the name of each level of excitement may be changeable by the user. Note that each stage of excitement may be read as an excitement level.
 ユーザは、図14と同様、信頼度の閾値設定領域105に含まれる閾値バー120を調整して、信頼度から信頼程度を決定するための閾値を決定する。例えば、コンテンツ反応検出では、信頼度が低くても運用上あまり問題ないので、ユーザは、当該閾値を低め(つまり緩め)に設定してもよい。 Similarly to FIG. 14, the user adjusts the threshold bar 120 included in the reliability threshold setting area 105 to determine the threshold for determining the reliability level from the reliability level. For example, in content reaction detection, even if the reliability is low, there is no problem in operation, so the user may set the threshold to be low (that is, relaxed).
 ユーザは、測定人数設定領域104に、測定最大人数を設定する。例えば、ユーザは、システム上対応可能な最大人数を設定してもよい。 The user sets the maximum number of people to be measured in the number of people to be measured setting area 104. For example, the user may set the maximum number of people that the system can handle.
 管理装置13は、設定された監視エリア8、各閾値、及び、測定最大人数を含む生体程度判定情報23を生成し、利用シーン「コンテンツ視聴反応検出」と対応付けてストレージ1003に保持する。これにより、管理装置13は、図5に示す監視処理において、利用シーン「コンテンツ視聴反応検出」が選択された場合、「コンテンツ視聴反応検出」用に適切に設定された生体程度判定情報23を利用できる。 The management device 13 generates biological degree determination information 23 including the set monitoring area 8, each threshold value, and the maximum number of people to be measured, and stores it in the storage 1003 in association with the usage scene "content viewing reaction detection". As a result, in the monitoring process shown in FIG. 5, when the usage scene "content viewing reaction detection" is selected, the management device 13 uses the biological grade determination information 23 appropriately set for "content viewing reaction detection". can.
<コンテンツ視聴反応検出用の表示設定情報>
 図22は、実施の形態1に係る利用シーン「コンテンツ視聴反応検出」用の表示設定情報24の設定画面200Cを示す図である。
<Display setting information for content viewing reaction detection>
FIG. 22 is a diagram showing a setting screen 200C of the display setting information 24 for the usage scene "content viewing reaction detection" according to the first embodiment.
 利用シーン「コンテンツ視聴反応検出」用の表示設定情報24の設定画面200Cは、図22に示すように、図8と同様、項目として、行動又は状態名と、設定名と、設定値とを有する。 As shown in FIG. 22, the setting screen 200C of the display setting information 24 for the usage scene "content viewing reaction detection" has an action or state name, a setting name, and a setting value as items, similar to FIG. 8. .
<<歩行中>>
 例えば、図22に示すように、行動又は状態名「歩行中」に、設定名「姿勢条件」、「動作条件」、「生体程度条件」、「アイコン名」が対応付けられる。
<<While walking>>
For example, as shown in FIG. 22, the behavior or state name "walking" is associated with the setting names "posture condition,""motioncondition,""living condition condition," and "icon name."
 設定名「姿勢条件」の設定値は、人物1の行動を「歩行中」と判定するための人物1の姿勢を示す。当該姿勢は、所定の姿勢リストから1つ選択されてよい。例えば、ユーザは、行動「歩行中」に対応付ける設定名「姿勢条件」の設定値として、所定の姿勢リストから「立位」を選択する。 The setting value of the setting name “posture condition” indicates the posture of the person 1 for determining the behavior of the person 1 as “walking”. One of the postures may be selected from a predetermined posture list. For example, the user selects "standing" from a predetermined posture list as the setting value of the setting name "posture condition" associated with the action "walking."
 設定名「動作条件」の設定値は、人物1の行動を「歩行中」と判定するための人物1の動作を示す。当該動作は、所定の動作リストから1つ選択されてよい。例えば、ユーザは、行動「歩行中」に対応付ける設定名「動作条件」の設定値として、所定の動作リストから「移動」を選択する。 The setting value of the setting name "operation condition" indicates the action of the person 1 for determining the action of the person 1 as "walking". One of the operations may be selected from a predetermined operation list. For example, the user selects "move" from a predetermined action list as the setting value of the setting name "operating condition" associated with the action "walking".
 設定名「生体程度条件」の設定値は、人物1の行動を「歩行中」と判定するための人物1の生体程度及び当該生体程度の補正量を示す。一般的に、歩行中の人物は、バイタル値が通常よりも高くなる傾向にある。そこで、ユーザは、行動「歩行中」に対応付ける設定名「生体程度条件」の設定値として、デフォルトの興奮程度の閾値を所定量高くするような補正量を設定してよい。これにより、人物1が歩行中のためにバイタル値が通常よりも高くなっているだけであるにも関わらず、端末装置14が、興奮程度を「関心あり」又は「興奮」と誤判定してしまう可能性を抑制できる。ただし、行動名「歩行中」に設定名「生体程度条件」を対応付けることは必須ではない。 The setting value of the setting name "biological degree condition" indicates the biological degree of the person 1 and the correction amount of the biological degree for determining the behavior of the person 1 as "walking". Generally, the vital values of a walking person tend to be higher than normal. Therefore, the user may set a correction amount that increases the default excitement level threshold by a predetermined amount as a setting value of the setting name "biological level condition" associated with the action "walking". As a result, the terminal device 14 incorrectly determines the degree of excitement as "interested" or "excited" even though the person 1 is walking and his/her vital values are higher than normal. The possibility of being lost can be suppressed. However, it is not essential to associate the action name "walking" with the setting name "living condition".
 設定名「アイコン名」の設定値は、人物1の行動を「歩行中」と判定した場合に使用するアイコンのファイル名を示す。 The setting value of the setting name "icon name" indicates the file name of the icon used when the behavior of the person 1 is determined to be "walking."
 例えば、端末装置14は、人物1の姿勢が設定名「姿勢条件」の設定値が示す「立位」であり、人物1の動作が設定名「動作」の設定値が示す「移動」であり、人物1の興奮程度が設定名「生体程度条件」の設定値によって補正された「無関心」である場合、当該人物1の行動を「歩行中」と判定し、設定名「アイコン名」の設定値が示すファイル名のアイコンを表示する。なお、表示方法の詳細については後述する。 For example, the terminal device 14 determines that the posture of the person 1 is "standing" indicated by the setting value of the setting name "posture condition", and the motion of the person 1 is "moving" indicated by the setting value of the setting name "movement". , if the degree of excitement of person 1 is "indifferent" corrected by the setting value of the setting name "biological degree condition", the behavior of the person 1 is determined to be "walking", and the setting name of "icon name" is determined. Displays the icon of the file name indicated by the value. Note that details of the display method will be described later.
<<静止中>>
 例えば、図22に示すように、行動又は状態名「静止中」に、設定名「姿勢条件」、「動作条件」、「生体程度条件」、「アイコン名」が対応付けられる。
<<Stationary>>
For example, as shown in FIG. 22, the behavior or state name "Standing" is associated with the setting names "posture condition,""motioncondition,""living condition condition," and "icon name."
 設定名「姿勢条件」の設定値は、人物1の行動を「静止中」と判定するための人物1の姿勢を示す。当該姿勢は、所定の姿勢リストから1つ選択されてよい。例えば、ユーザは、行動「静止中」に対応付ける設定名「姿勢条件」の設定値として、所定の姿勢リストから「立位」を選択する。 The setting value of the setting name "posture condition" indicates the posture of the person 1 for determining the behavior of the person 1 as "still". One of the postures may be selected from a predetermined posture list. For example, the user selects "standing" from a predetermined posture list as the setting value of the setting name "posture condition" associated with the action "resting".
 設定名「動作条件」の設定値は、人物1の行動を「静止中」と判定するための人物1の動作を示す。当該動作は、所定の動作リストから1つ選択されてよい。例えば、ユーザは、行動「静止中」に対応付ける設定名「動作条件」の設定値として、所定の動作リストから「停止」を選択する。 The setting value of the setting name "operation condition" indicates the action of the person 1 for determining the action of the person 1 as "still". One of the operations may be selected from a predetermined operation list. For example, the user selects "stop" from a predetermined action list as the setting value of the setting name "operating condition" associated with the action "resting".
 設定名「生体程度条件」の設定値は、人物1の行動を「静止中」と判定するための人物1の生体程度及び当該生体程度の補正量を示す。一般的に、静止中の人物は、バイタル値が通常よりも低くなる傾向にある。そこで、ユーザは、行動「静止中」に対応付ける設定名「生体程度条件」の設定値として、デフォルトの興奮程度の閾値を所定量低くするような補正量を設定してよい。これにより、人物1が静止中のためにバイタル値が通常よりも低くなっているだけであるにも関わらず、端末装置14が、興奮程度を「関心あり」と誤判定してしまう可能性を抑制できる。ただし、行動名「静止中」に設定名「生体程度条件」を対応付けることは必須ではない。 The setting value of the setting name "Living Condition" indicates the living body level of the person 1 and the correction amount of the living body level for determining the behavior of the person 1 as being "at rest." Generally, when a person is stationary, their vital values tend to be lower than normal. Therefore, the user may set a correction amount that lowers the default excitement level threshold by a predetermined amount as a setting value of the setting name "biological level condition" associated with the action "resting". This eliminates the possibility that the terminal device 14 may erroneously determine the degree of excitement as "interested" even though the person 1 is stationary and his/her vital values are lower than normal. It can be suppressed. However, it is not essential to associate the action name "Standing" with the setting name "Living condition".
 設定名「アイコン名」の設定値は、人物1の行動を「静止中」と判定した場合に使用するアイコンのファイル名を示す。 The setting value of the setting name "icon name" indicates the file name of the icon to be used when the behavior of person 1 is determined to be "still".
 例えば、端末装置14は、人物1の姿勢が設定名「姿勢条件」の設定値が示す「立位」であり、人物1の動作が設定名「動作」の設定値が示す「停止」であり、人物1の興奮程度が設定名「生体程度条件」の設定値によって補正された「無関心」である場合、当該人物1の行動を「静止中」と判定し、設定名「アイコン名」の設定値が示すファイル名のアイコンを表示する。なお、表示方法の詳細については後述する。 For example, the terminal device 14 determines that the posture of the person 1 is "standing" indicated by the setting value of the setting name "posture condition", and the motion of the person 1 is "stop" indicated by the setting value of the setting name "movement". , if the degree of excitement of person 1 is "indifferent" corrected by the setting value of the setting name "biological degree condition", the behavior of the person 1 is determined to be "resting", and the setting name of "icon name" is determined. Displays the icon of the file name indicated by the value. Note that details of the display method will be described later.
<<注目中>>
 例えば、図22に示すように、行動又は状態名「注目中」に、設定名「興奮程度条件」、「顔の向き条件」、「アイコン色」が対応付けられる。
<<Attention>>
For example, as shown in FIG. 22, the action or state name "Attention" is associated with setting names "Excitement level condition", "Face orientation condition", and "Icon color".
 設定名「興奮程度条件」の設定値は、人物1の状態をサイネージ15に表示されているコンテンツに「注目中」と判定するための人物の興奮程度を示す。例えば、ユーザは、状態「注目中」に対応付ける設定名「興奮程度条件」の設定値として、「関心あり」と「興奮」を設定する。 The setting value of the setting name “excitement level condition” indicates the degree of excitement of the person for determining the state of the person 1 as “attention” to the content displayed on the signage 15. For example, the user sets "interested" and "excited" as setting values for the setting name "excitement level condition" associated with the state "attention".
 設定名「顔の向き条件」の設定値は、人物1の状態を「注目中」と判定するための人物の顔の向きを示す。例えば、ユーザは、状態「注目中」に対応付ける設定名「顔の向き条件」の設定として、サイネージ15の正面方向を向いたときの顔の角度の範囲を設定する。なお、人物の顔の向きは、生体情報21に基づいて検知されてよい。 The setting value of the setting name "face orientation condition" indicates the direction of the person's face for determining the state of person 1 as "attention". For example, the user sets the range of angles of the face when facing in the front direction of the signage 15 as a setting for the setting name "face orientation condition" associated with the state "attention". Note that the direction of the person's face may be detected based on the biometric information 21.
 設定名「アイコン色」の設定値は、人物1の状態を「注目中」と判定した場合に使用するアイコンの色を示す。 The setting value of the setting name "icon color" indicates the color of the icon to be used when the state of person 1 is determined to be "attention".
 例えば、端末装置14は、人物1の興奮程度が設定名「興奮程度条件」の設定値が示す「関心あり」又は「興奮」であり、人物1の顔の向きが設定名「顔の向き条件」の設定値が示す角度の範囲内である場合、当該人物1の状態を「注目中」と判定し、設定名「アイコン色」の設定値が示す色でアイコンを表示する。なお、表示方法の詳細については後述する。 For example, the terminal device 14 determines that the degree of excitement of the person 1 is "interested" or "excited" indicated by the setting value of the setting name "excitement level condition", and the direction of the face of the person 1 is the setting value of the setting name "face orientation condition". ”, the state of the person 1 is determined to be “attention”, and the icon is displayed in the color indicated by the setting value of the setting name “icon color”. Note that details of the display method will be described later.
<サイネージ設定情報>
 図23は、実施の形態1に係るサイネージ設定情報600の一例を示す図である。
<Signage setting information>
FIG. 23 is a diagram illustrating an example of signage setting information 600 according to the first embodiment.
 サイネージ設定情報600は、コンテンツ視聴反応の検出結果に応じて、サイネージ15におけるコンテンツの表示を変化させるための設定を含む。サイネージ設定情報600は、項目として、興奮程度と、設定値とを有する。 The signage setting information 600 includes settings for changing the content display on the signage 15 according to the detection result of the content viewing reaction. The signage setting information 600 has as items the degree of excitement and a setting value.
 例えば、図23に示すサイネージ設定情報600の1行目に示すように、ユーザは、興奮程度「興奮」に対して、設定値として、サイネージ15に表示中のコンテンツの表示時間を10秒長くする設定を対応付ける。この場合、端末装置14は、監視エリア8内に興奮程度「興奮」の人物1が存在する場合、サイネージ15に表示中のコンテンツの表示時間を10秒長くする。 For example, as shown in the first line of the signage setting information 600 shown in FIG. 23, the user increases the display time of the content being displayed on the signage 15 by 10 seconds as a setting value for the excitement level "excitement". Map settings. In this case, the terminal device 14 increases the display time of the content being displayed on the signage 15 by 10 seconds when the person 1 with the excitement level "excited" is present in the monitoring area 8.
 例えば、図23に示すサイネージ設定情報600の2行目に示すように、ユーザは、興奮程度「関心あり」に対して、設定値として、サイネージ15に表示中のコンテンツの表示時間を3秒長くする設定を対応付ける。この場合、端末装置14は、監視エリア8内に興奮程度「関心あり」の人物1が存在する場合、サイネージ15に表示中のコンテンツの表示時間を3秒長くする。 For example, as shown in the second line of the signage setting information 600 shown in FIG. 23, the user increases the display time of the content currently displayed on the signage 15 by 3 seconds as a setting value for the excitement level "interested". Map the settings that you want to use. In this case, the terminal device 14 increases the display time of the content being displayed on the signage 15 by 3 seconds if the person 1 with the level of excitement "interested" is present in the monitoring area 8.
 このように、サイネージ15の前に存在する人物の興奮程度に応じてコンテンツの表示時間を調節することにより、コンテンツの効果をより高めることができる。 In this way, by adjusting the display time of the content according to the degree of excitement of the person in front of the signage 15, the effect of the content can be further enhanced.
<コンテンツ視聴反応検出用の監視画面>
 図24は、実施の形態1に係るサイネージ15の管理者向けの監視画面400Fの一例を示す図である。
<Monitoring screen for detecting content viewing reactions>
FIG. 24 is a diagram showing an example of a monitoring screen 400F for the administrator of the signage 15 according to the first embodiment.
 監視画面400Fは、図24に示すように、コンテンツ領域421、人物領域422、注目度領域423、及び、グラフ領域424を含んで構成される。 As shown in FIG. 24, the monitoring screen 400F includes a content area 421, a person area 422, an attention area 423, and a graph area 424.
 端末装置14は、コンテンツ領域421に、サイネージ15に表示中のコンテンツを表示する。 The terminal device 14 displays the content being displayed on the signage 15 in the content area 421.
 端末装置14は、人物領域422に、検出された各人物の行動又は状態をアイコンで表示する。図24に示すように、端末装置14は、検出された人数分のアイコンを表示してよい。例えば、検出した人物の行動が「歩行中」である場合、端末装置14は、歩行中のアイコン521を表示する。例えば、検出した人物の行動が「静止中」である場合、端末装置14は、静止中のアイコン522を表示する。例えば、検出した人物の興奮程度が「興奮」である場合、「興奮」に対応する色(例えば赤色)のアイコン523を表示する。例えば、検出した人物の興奮程度が「関心あり」である場合、「関心あり」に対応する色(例えばオレンジ)のアイコン(図示しない)を表示する。 The terminal device 14 displays the behavior or status of each detected person in the person area 422 as an icon. As shown in FIG. 24, the terminal device 14 may display icons for the number of detected persons. For example, if the detected behavior of the person is "walking", the terminal device 14 displays a walking icon 521. For example, if the detected person's behavior is "resting", the terminal device 14 displays the "resting" icon 522. For example, when the degree of excitement of the detected person is "excitement", an icon 523 of a color (for example, red) corresponding to "excitement" is displayed. For example, if the level of excitement of the detected person is "interested", an icon (not shown) in a color (for example, orange) corresponding to "interested" is displayed.
 端末装置14は、注目度領域423に、注目度を表示する。端末装置14は、検出された人物のうち、表示設定情報24において状態が「注目中」と判定された人物の割合に基づいて、注目度を算出してよい。 The terminal device 14 displays the degree of interest in the degree of interest area 423. The terminal device 14 may calculate the degree of attention based on the proportion of the detected persons whose status is determined to be "attention" in the display setting information 24.
 端末装置14は、グラフ領域424に、注目度の時間変化を示すグラフGRを表示する。グラフ領域414のグラフGRは、横軸が時間を示し、縦軸が注目度を示す。端末装置14は、随時グラフGRを更新してよい。 The terminal device 14 displays, in the graph area 424, a graph GR showing changes in attention level over time. In the graph GR in the graph area 414, the horizontal axis indicates time and the vertical axis indicates the degree of attention. The terminal device 14 may update the graph GR at any time.
 端末装置14は、コンテンツの表示内容と、そのコンテンツが表示されていたときの注目度とを対応付けて、コンテンツ注目度情報を生成しストレージ1003に保持してよい。これにより、サイネージ15の管理者は、コンテンツ注目度情報を用いて、サイネージ15に表示されたコンテンツのうち、どのコンテンツがどのくらい注目されたか等を後で分析することができる。 The terminal device 14 may generate content attention level information and hold it in the storage 1003 by associating the displayed contents of the content with the attention level when the content was being displayed. Thereby, the administrator of the signage 15 can use the content attention degree information to later analyze which content among the contents displayed on the signage 15 has attracted how much attention.
