Description

見守り装置、見守り方法及び見守りプログラムMonitoring device, monitoring method and monitoring program
　本発明は、見守り装置、見守り方法及び見守りプログラムに関する。 The present invention relates to a watching device, a watching method, and a watching program.
　近時先進国では、単身で生活する高齢者を、遠隔地から見守り者が見守ることが一般的になっている。特に被見守り者が認知症を発症する可能性がある場合、その予兆を少しでも早く知ることが、認知症発症の予防には重要である。 Recently, in developed countries, it has become common for elderly people living alone to be watched over by guardians from a remote location. In particular, when the person being watched over may develop dementia, it is important to know the signs as soon as possible to prevent the onset of dementia.
　特許文献１の認知症情報出力システムにおいては、被見守り者のベッドの周辺に配置されたセンサが、被見守り者の体動量を１時間ずつ１日２４回計測する。被見守り者が健常である場合、体動量が計測される時間帯は、１日のうち朝から夜までに集中する。被見守り者が認知症を発症すると、体動量が計測される時間帯は、ほぼ全日に跨り、かつ、各時間帯の体動量は、不規則になる。当該システムは、このような体動量の特徴を検知し、被見守り者の認知症の発症を予測する。 In the dementia information output system of Patent Document 1, sensors placed around the bed of the person being watched over measure the amount of body movement of the person being watched over every hour 24 times a day. When the person being watched over is in good health, the time period during which the amount of body movement is measured is concentrated from morning to night in one day. When the person being watched over develops dementia, the time periods in which the amount of body movement is measured span almost all days, and the amount of body movement in each time period becomes irregular. The system detects such characteristics of the amount of body movement and predicts the onset of dementia in the person being watched over.
特許第６６３１９３１号明細書Patent No. 6631931
　高齢者が認知症を発症している可能性を、体動量だけで正確に予測することは困難である。例えば、外出、家事、食事、睡眠等、認知症を防ぐ活動を被見守り者が十分に行っているか否かを知ることが、正確な予測には必須である。つまり、被見守り者が何をどの程度行っているかを測定すること、換言すれば活動の内容を量的かつ質的に計測することが重要である。これは、身体的機能や認知機能が低下していることの予測においても同様である。しかしながら、特許文献１の認知症情報出力システムは、被見守り者の体動を量的に計測するに留まる。
　そこで、本発明は、被見守り者の活動を量的かつ質的に計測することを目的とする。 It is difficult to accurately predict the possibility of developing dementia in elderly people based only on the amount of body movement. For example, it is essential for accurate prediction to know whether the person being watched is doing enough activities to prevent dementia, such as going out, doing housework, eating, and sleeping. In other words, it is important to measure what the person being watched over does and to what extent, in other words, to measure the contents of the activity both quantitatively and qualitatively. The same is true for predicting decline in physical and cognitive function. However, the dementia information output system of Patent Literature 1 only quantitatively measures body movements of the person being watched over.
Accordingly, an object of the present invention is to quantitatively and qualitatively measure the activity of the person being watched over.
　本発明の見守り装置は、被見守り者の住居に備え付けられたセンサから、前記被見守り者の体動に関する量的生活指標及び前記被見守り者の生活習慣に関する質的生活指標を受信するセンサ情報取得部と、前記量的生活指標及び前記質的生活指標の変化である生活変化の類型を受け付け、前記受け付けた生活変化が実際に発生した場合、前記実際に発生した生活変化を、前記被見守り者又は前記被見守り者を見守る見守り者に通知するセンサ情報処理部と、を備えることを特徴とする。
　その他の手段については、発明を実施するための形態のなかで説明する。 The watching device of the present invention acquires sensor information for receiving a quantitative life index related to body movements of the person being watched over and a qualitative life index related to the lifestyle habits of the person being watched over from sensors installed in the residence of the person being watched over. and a type of life change that is a change in the quantitative life index and the qualitative life index, and when the received life change actually occurs, the actually occurred life change is recognized by the person being watched over. or a sensor information processing unit that notifies a person watching over the person being watched over.
Other means are described in the detailed description.

（生活情報）
　図２は、生活情報３１の一例を示す図である。生活情報３１においては、時間帯欄１０１に記憶された時間帯に関連付けて、量的生活指標欄１０２には量的生活指標が、質的生活指標欄１０３には質的生活指標が、第三者コメント欄１０４には第三者コメントが記憶されている。
　時間帯欄１０１の時間帯は、１日２４時間を構成する均等な長さの時間帯である。図２の例では、長さは１時間（６０分）である。 (living information)
FIG. 2 is a diagram showing an example of life information 31. As shown in FIG. In the life information 31, the quantitative life index field 102 contains the quantitative life index, the qualitative life index field 103 contains the qualitative life index, and the third Third party comments are stored in the third party comment column 104 .
The time zone in the time zone column 101 is a time zone of even length that constitutes 24 hours a day. In the example of Figure 2, the length is one hour (60 minutes).
　量的生活指標欄１０２の量的生活指標は、被見守り者５の体動を、外出、運動、家事、食事、睡眠等の態様に関係なく量的に示した指標であり、具体的には、以下を含む。
・活動量（欄１０２ａ）は、被見守り者５の身体の活性化水準の積算値である。活動量は、センサ２（人感センサ）によって計測され得るし、被見守り者５が装着するウエアラブルセンサ（図示せず）によっても計測され得る。“＃”は、計測された値を省略的に示している（以下同様）。
・部屋内移動速度（欄１０２ｂ）は、寝室６ａ、玄関６ｂ及び台所６ｃを含む住居６内の各居室内において、被見守り者５が移動した平均速度である。例えば、被見守り者５がある時間帯において２回、まず３０秒間に渡って居室内を５メートル移動し、その後しばらくして３０秒間に渡って居室内を５メートル移動したとする。この場合、その時間帯の部屋内移動速度は、時速６００メートルである。部屋内移動速度は、カメラ機能を有するセンサ２によって計測され得る。 The quantitative life index in the quantitative life index column 102 is an index that quantitatively indicates the body movement of the person being watched 5 regardless of the mode of going out, exercising, housework, eating, sleeping, etc. Specifically, , including:
- The amount of activity (column 102a) is an integrated value of the activation level of the body of the person being watched over 5 . The amount of activity can be measured by the sensor 2 (human sensor), and can also be measured by a wearable sensor (not shown) worn by the person being watched over 5 . "#" abbreviates the measured value (same below).
The in-room movement speed (column 102b) is the average speed at which the person-to-be-watched 5 moved in each room in the residence 6 including the bedroom 6a, the entrance 6b, and the kitchen 6c. For example, it is assumed that the person 5 to be watched over twice in a certain time zone first moves 5 meters in the living room for 30 seconds, and after a while moves 5 meters in the living room for 30 seconds. In this case, the moving speed in the room during that time period is 600 meters per hour. The moving speed within the room can be measured by the sensor 2 having a camera function.
・部屋間移動速度（欄１０２ｃ）は、寝室６ａ、玄関６ｂ及び台所６ｃを含む住居６内の居室間を被見守り者５が移動した平均速度である。例えば、被見守り者５がある時間帯において１回だけ１分間に渡って廊下を１０メートル移動した場合、その時間帯の部屋間移動速度は、時速６００メートルである。
・姿勢変化速度（欄１０２ｄ）は、被見守り者５が移動（歩行）していない状態において、身体の一部（頭部、腰部等）が動く平均速度である。姿勢変化速度は、カメラ機能を有するセンサ２によって計測され得る。
・転倒回数（欄１０２ｅ）は、被見守り者が転倒した回数である。転倒回数は、カメラ機能を有するセンサ２によって計測され得るし、３次元加速度計を備えるウエアラブルセンサによっても計測され得る。 The moving speed between rooms (column 102c) is the average speed at which the person-to-be-watched 5 moved between rooms in the residence 6 including the bedroom 6a, the entrance 6b and the kitchen 6c. For example, when the person being watched 5 moves 10 meters in a hallway for one minute only once during a certain time period, the room-to-room movement speed during that time period is 600 meters per hour.
The posture change speed (column 102d) is the average speed at which a part of the body (head, waist, etc.) moves when the person being watched 5 is not moving (walking). The attitude change speed can be measured by a sensor 2 having a camera function.
- The number of falls (column 102e) is the number of times the person being watched over has fallen. The number of falls can be measured by the sensor 2 having a camera function, and can also be measured by a wearable sensor equipped with a three-dimensional accelerometer.
　質的生活指標欄１０３の質的生活指標は、被見守り者５の体動のうち身体的機能や認知機能の低下といった虚弱状態防止の観点から質的に有意なものを示す指標である。質的生活指標は、全体として被見守り者の生活習慣を示し、個々の具体的な指標として以下を含む。
・外出回数（欄１０３ａ）は、被見守り者５がドア１０を開けて住居６外に移動した回数である。外出回数は、ドア１０によって計測され得る。
・運動時間（欄１０３ｂ）は、被見守り者５が虚弱状態防止のための所定の運動（体操）を行っている時間である。運動時間は、カメラ機能を有するセンサ２によって計測され得る。見守り装置１は、センサ２が撮像した画像から、例えばパタンマッチングによって、所定の運動に該当する画像を切り出す。 The qualitative life index in the qualitative life index column 103 is an index that indicates a qualitatively significant body movement of the person being watched over 5 from the viewpoint of preventing a frail state such as deterioration of physical function and cognitive function. Qualitative life indicators indicate the lifestyle of the person being watched as a whole, and include the following as individual specific indicators.
- The number of times of going out (column 103a) is the number of times the watched person 5 opened the door 10 and moved out of the residence 6. The number of times of going out can be measured by the door 10 .
- The exercise time (column 103b) is the time during which the person being watched 5 performs a predetermined exercise (gymnastics) to prevent a frail state. Exercise time can be measured by a sensor 2 having a camera function. The watching device 1 cuts out an image corresponding to a predetermined movement from the image captured by the sensor 2, for example, by pattern matching.
・家事時間（欄１０３ｃ）は、被見守り者５が食事の準備、清掃、洗濯等の家事を行っている時間である。家事時間は、カメラ機能を有するセンサ２によって計測され得るし、冷蔵庫８及び加熱調理器９を含む家電機器によっても計測され得る。見守り装置１は、センサ２が撮像した画像から、例えばパタンマッチングによって、家事に該当する画像を切り出す。
・食事時間（欄１０３ｄ）は、被見守り者５が食事を行っている時間である。食事時間は、カメラ機能を有するセンサ２によって計測され得る。見守り装置１は、センサ２が撮像した画像から、例えばパタンマッチングによって、食事に該当する画像を切り出す。 - The housework time (column 103c) is the time when the watched person 5 is doing housework such as preparing meals, cleaning, and washing. Housework time can be measured by a sensor 2 having a camera function, and can also be measured by home electric appliances including a refrigerator 8 and a heating cooker 9 . The watching device 1 cuts out an image corresponding to housework from the image captured by the sensor 2, for example, by pattern matching.
- The meal time (column 103d) is the time when the person-to-be-watched 5 is eating. A meal time can be measured by a sensor 2 having a camera function. The watching device 1 cuts out an image corresponding to a meal from the image captured by the sensor 2, for example, by pattern matching.
・リラックス時間（欄１０３ｅ）は、被見守り者５がリラックスしている時間である。リラックスの具体的な態様は、被見守り者５ごとに異なる。リラックス時間は、例えば“読書時間”、“テレビ視聴時間”、“インターネット検索時間”等であり得る。リラックス時間は、カメラ機能を有するセンサ２によって計測され得る。見守り装置１は、センサ２が撮像した画像から、例えばパタンマッチングによって、リラックスの具体的な態様に該当する画像を切り出す。リラックス時間は、被見守り者端末装置７によっても、ブラウザ使用時間として計測され得る。さらに、リラックス時間は、ウエアラブルセンサによっても、呼吸数、血圧、心拍数等が所定の範囲の値を取る時間として計測され得る。 • The relaxation time (column 103e) is the time during which the person being watched 5 is relaxing. A specific mode of relaxation differs for each watched person 5 . Relaxation time can be, for example, "time spent reading", "time spent watching TV", "time spent searching the Internet", and the like. A relaxation time can be measured by a sensor 2 having a camera function. The watching device 1 cuts out an image corresponding to a specific mode of relaxation from the image captured by the sensor 2, for example, by pattern matching. The relaxation time can also be measured as the browser usage time by the terminal device 7 of the person being watched over. Furthermore, the relaxation time can also be measured by a wearable sensor as the time during which the respiratory rate, blood pressure, heart rate, etc. take values within a predetermined range.
・睡眠時間（欄１０３ｆ）は、被見守り者５がベッドで睡眠している時間である。睡眠時間は、カメラ機能を有するセンサ２によって計測され得る。見守り装置１は、センサ２が撮像した画像から、例えばパタンマッチングによって、睡眠に該当する画像を切り出す。睡眠時間は、帽子型のウエアラブルセンサによっても、脳波が睡眠を示している時間として計測され得る。 - The sleep time (column 103f) is the time the watched person 5 is sleeping in bed. Sleep time can be measured by a sensor 2 having a camera function. The watching device 1 cuts out an image corresponding to sleep from the image captured by the sensor 2, for example, by pattern matching. Sleeping time can also be measured by a hat-shaped wearable sensor as the time during which the electroencephalogram indicates sleep.
　前記より明らかなように、外出回数、運動時間、家事時間、食事時間、リラックス時間及び睡眠時間は、それ自身、“回数”又は“時間”という量を示してはいる。しかしながら、それらから構成される質的生活指標は、何をどの程度行ったかという生活の質（生活習慣）そのものである。 As is clear from the above, the number of times you go out, the time spent exercising, the time spent doing housework, the time spent eating, the time spent relaxing, and the time spent sleeping indicate the amount of "number of times" or "time". However, the qualitative life index composed of them is the quality of life (lifestyle) itself, which is what and how much one has done.
　第三者コメント欄１０４の第三者コメントは、見守り者及び被見守り者以外の第三者が、量的生活指標及び／又は質的生活指標に対して付した評価であってもよいし、予め準備された質問に対する被見守り者の回答に対する評価であってもよい。第三者とは、例えば、自治体職員、介護者、医師等である。“＃＃”は、評価の文字列を省略的に示している。第三者コメントの文字列の例として、例えば以下が挙げられる。
・“○○日前にも、同じ生活変化がありました。”
・“自治体の〇〇相談をお受けください。”
・“〇〇の変化は、あまり気にすることはありません。”
・“〇〇の変化に特に留意し、早めに医師に相談してください。”
　第三者コメントは、各時間帯に対応していてもよいし、１日に対応していてもよい。 The third-party comment in the third-party comment field 104 may be an evaluation given by a third party other than the watcher and the person being watched over the quantitative life index and/or the qualitative life index, It may be an evaluation of the watched person's answer to a question prepared in advance. A third party is, for example, a local government employee, a caregiver, a doctor, or the like. "##" abbreviates the evaluation character string. Examples of character strings for third-party comments include the following.
・“○○ days ago, I had the same change in my life.”
・"Please accept the 〇〇 consultation of the local government."
・"I don't really care about the change in 〇〇."
・"Pay particular attention to changes in 〇〇 and consult a doctor as soon as possible."
The third-party comment may correspond to each time period, or may correspond to one day.
（通知規則）
　図３は、通知規則３２の一例を示す図である。通知規則３２においては、変化ＩＤ欄１１１に記憶された変化ＩＤに関連付けて、生活変化欄１１２には生活変化が、方向欄１１３には方向が、優先度欄１１４には優先度が、通知先欄１１５には通知フラグが、通知内容欄１１６には通知内容が、インセンティブ欄１１７にはインセンティブが記憶されている。 (Notification Rules)
FIG. 3 is a diagram showing an example of the notification rule 32. As shown in FIG. In the notification rule 32, the change ID stored in the change ID column 111 is associated with the change in life in the change ID column 112, the direction in the direction column 113, the priority in the priority column 114, and the notification destination. The column 115 stores notification flags, the notification content column 116 stores notification content, and the incentive column 117 stores incentives.
　変化ＩＤ欄１１１の変化ＩＤは、生活変化（直ちに後記）を一意に特定する識別子である。
　生活変化欄１１２の生活変化は、量的生活指標及び／又は質的生活指標の時系列変化の類型である。例えば“直近の５日間に比して、活動量が１０％減少した”は、図２の活動量（欄１０２ａ）の変化に対応する。同様に、“直近の５日間に比して、外出回数が３０％減少した”は、図２の外出回数（欄１０３ａ）の変化に対応する。“直近の５日間に比して、食事時間が１０％減少した”は、図２の食事時間（欄１０３ｄ）の変化に対応する。この例では、１つの変化ＩＤに対して、３つの生活変化が対応している。３つの生活変化相互の関係は、“論理和”であってもよいし“論理積”であってもよい。 A change ID in the change ID column 111 is an identifier that uniquely identifies a lifestyle change (described immediately below).
The lifestyle change in the lifestyle change column 112 is a type of chronological change in the quantitative lifestyle index and/or the qualitative lifestyle index. For example, "the amount of activity has decreased by 10% compared to the last 5 days" corresponds to the change in the amount of activity (column 102a) in FIG. Similarly, "the number of times of going out has decreased by 30% compared to the last five days" corresponds to the change in the number of times of going out (column 103a) in FIG. “Meal time decreased by 10% compared to the last 5 days” corresponds to change in meal time (column 103d) in FIG. In this example, three lifestyle changes correspond to one change ID. The relationship among the three lifestyle changes may be "logical sum" or "logical product".
　さらに、生活変化は、“第三者コメントが「〇〇〇」の文字列を含む”であってもよい。このように生活変化を定義すると、見守り装置１は、専門家等の意見をも反映したうえで、通知（詳細後記）の必要性を判断することができる。 Furthermore, the lifestyle change may be "a third party comment includes a character string of '000'". After reflecting, it is possible to judge the necessity of notification (details will be described later).
　方向欄１１３の方向は、“悪化”又は“改善”のいずれかである。“悪化”は、生活変化が虚弱状態の進行を示していることを意味し、“改善”は、生活変化が虚弱状態の抑制又は虚弱状態からの回復を示していることを意味する。
　優先度欄１１４の優先度は、方向が“悪化”である場合における、生活変化の深刻さの程度である。“レベル”に続く数字が大きいほど、深刻さの程度は大きい。見守り装置１のセンサ情報処理部２２は、図２の量的生活指標（欄１０２ａ～１０２ｅ）及び／又は質的生活指標（欄１０３ａ～１０３ｆ）の例えば加重平均に基づき、優先度を決定してもよい。 The direction in direction column 113 is either "deteriorated" or "improved". "Worsening" means that the lifestyle change indicates progression of frailty, and "improvement" means that the lifestyle change indicates suppression of frailty or recovery from frailty.
The priority in the priority column 114 is the degree of seriousness of life change when the direction is "deterioration". The higher the number following "level", the greater the degree of seriousness. The sensor information processing unit 22 of the watching device 1 determines the priority based on, for example, the weighted average of the quantitative life indicators (columns 102a to 102e) and/or the qualitative life indicators (columns 103a to 103f) in FIG. good too.
　通知先欄１１５の通知先フラグは、生活変化があったことを知らせる通知（以降、単に“通知”と呼ぶ）の送り先を示す“○”である。通知は、見守り者の見守り者端末装置３及び／又は被見守り者５の被見守り者端末装置７に送信される。“○”に添えられた“Ｐ”は、プッシュ通知を示す。見守り者端末装置３又は被見守り者端末装置７にプッシュ通知が着信すると、見守り者又は被見守り者７による特段の操作を受け付けるまでもなく、通知が着信した旨が自動的に表示される。 The notification destination flag in the notification destination column 115 is "○" indicating the destination of the notification (hereinafter simply referred to as "notification") informing that there has been a lifestyle change. The notification is sent to the watching person's terminal device 3 and/or the watched person's terminal device 7 of the watched person 5 . “P” attached to “○” indicates push notification. When the watcher terminal device 3 or the watched person terminal device 7 receives the push notification, the reception of the notification is automatically displayed without receiving any special operation by the watcher or the watched person 7. - 特許庁

　１又は複数の通知内容が、見守り者及び被見守り者ごとに定義される。なお、１つの“忠告”は、１つの変化ＩＤに関連付けられていてもよいし、１つの生活変化に関連付けられていてもよい。“激励”についても同様である。
　インセンティブ欄１１７のインセンティブは、被見守り者に付与される経済的価値（ポイント）である。被見守り者に対して当初の残高として、例えば“１００ポイント”が与えられ、通知がなされる都度、インセンティブの数値が残高に対して増減される。方向が“悪化”である場合、インセンティブの符号は“負”であり、優先度（レベル）が大きくなる程、絶対値も大きくなる。方向が“改善”である場合、インセンティブの符号は“正”であり、生活変化の度合いが大きくなる程、絶対値も大きくなる。 One or more notification contents are defined for each watcher and watched person. Note that one “advice” may be associated with one change ID, or may be associated with one lifestyle change. The same is true for “encouragement”.
The incentive in the incentive column 117 is the economic value (points) given to the watched person. For example, "100 points" are given as an initial balance to the person being watched over, and the incentive value is increased or decreased with respect to the balance each time a notice is given. If the direction is "worse", the sign of the incentive is "negative", and the higher the priority (level), the higher the absolute value. When the direction is "improvement", the sign of the incentive is "positive", and the greater the degree of lifestyle change, the greater the absolute value.
（処理手順）
　図４は、処理手順のフローチャートである。当該処理手順を開始する前提として、図１に記載する環境が既に整っているものとする。
　ステップＳ２０１において、見守り装置１のセンサ情報処理部２２は、通知規則３２（図３）を受け付ける。具体的には、見守り者が見守り者端末装置３又は見守り装置１の入力装置１２を介して、通知規則３２を入力するのを受け付ける。見守り者は、表形式の通知規則３２を画面上で手動入力してもよいし、既に完成している電子データを入力装置１２に読み取らせてもよい。 (Processing procedure)
FIG. 4 is a flow chart of the processing procedure. It is assumed that the environment shown in FIG. 1 has already been prepared as a prerequisite for starting the processing procedure.
In step S201, the sensor information processing unit 22 of the watching device 1 receives the notification rule 32 (FIG. 3). Specifically, input of the notification rule 32 by the watcher via the watcher's terminal device 3 or the input device 12 of the watching device 1 is accepted. The watcher may manually input the notification rule 32 in tabular form on the screen, or may cause the input device 12 to read already completed electronic data.
　見守り者以外の任意の者が、通知規則３２を入力することもできる。通知規則３２を入力する者がいない場合、センサ情報処理部２２は、任意の装置に記憶されている完成済の標準的な通知規則３２を自動的に入力してもよい。 Any person other than the watcher can also enter the notification rule 32. If no one enters the notification rule 32, the sensor information processor 22 may automatically enter a completed standard notification rule 32 stored in any device.
　見守り者は、１つの変化ＩＤ又は１つの生活変化に関連付けて、具体的なメッセージ（忠告又は激励の文言）を関連付けて入力してもよい。すると、センサ情報処理部２２は、１つの変化ＩＤ又は１つの生活変化に関連付けて、メッセージを補助記憶装置１５に記憶する。説明の都合上、その後、監視期間の開始時刻（例えば翌日の午前０時００分００秒）が到来したとする。 The watcher may input a specific message (words of advice or encouragement) in association with one change ID or one life change. Then, the sensor information processing unit 22 stores the message in the auxiliary storage device 15 in association with one change ID or one life change. For convenience of explanation, it is assumed that the start time of the monitoring period (for example, 00:00:00 AM on the next day) has arrived thereafter.
　ステップＳ２０２において、見守り装置１のセンサ情報取得部２１は、量的生活指標を受け付ける。具体的には、センサ情報取得部２１は、センサ２（カメラ及びウエアラブルセンサを含む）から、量的生活指標（図２の欄１０２ａ～１０２ｅ）を取得（受信）する。センサ情報取得部２１は、区切りとなる所定の時刻（午前１時００分００秒）まで、当該処理を連続的又は間欠的に実行する。 In step S202, the sensor information acquisition unit 21 of the watching device 1 accepts the quantitative life index. Specifically, the sensor information acquisition unit 21 acquires (receives) quantitative life indices (columns 102a to 102e in FIG. 2) from the sensors 2 (including cameras and wearable sensors). The sensor information acquisition unit 21 continuously or intermittently executes the process until a predetermined time (1:00:00 am) that serves as a delimiter.
　ステップＳ２０３において、センサ情報取得部２１は、質的生活指標を受け付ける。具体的には、センサ情報取得部２１は、センサ２（カメラ及びウエアラブルセンサを含む）、冷蔵庫８、加熱調理器９又はドア１０から、質的生活指標（図２の欄１０３ａ～１０３ｆ）を取得（受信）する。センサ情報取得部２１は、区切りとなる所定の時刻（午前１時００分００秒）まで、当該処理を連続的又は間欠的に実行する。なお、ステップＳ２０２のタイミングとステップＳ２０３のタイミングは、同一であるものとする。いま、説明の都合上、“午前１時００分００秒”が到来したとする。 In step S203, the sensor information acquisition unit 21 accepts the quality of life index. Specifically, the sensor information acquisition unit 21 acquires quality life indicators (columns 103a to 103f in FIG. 2) from the sensor 2 (including a camera and a wearable sensor), the refrigerator 8, the cooking device 9, or the door 10. (receive). The sensor information acquisition unit 21 continuously or intermittently executes the process until a predetermined time (1:00:00 am) that serves as a delimiter. It is assumed that the timing of step S202 and the timing of step S203 are the same. For convenience of explanation, it is now assumed that "1:00:00 AM" has arrived.
　ステップＳ２０４において、見守り装置１のセンサ情報処理部２２は、第三者コメントを受け付ける。具体的には、第１に、センサ情報処理部２２は、第三者が操作する端末装置（図示せず）にステップＳ２０２において取得した量的生活指標及びステップＳ２０３において取得した質的生活指標を表示する。
　第２に、センサ情報処理部２２は、第三者が、当該量的生活指標及び当該質的生活指標に対するコメントを、第三者が操作する端末装置を介して入力するのを受け付ける。 In step S204, the sensor information processing unit 22 of the watching device 1 receives a third party comment. Specifically, first, the sensor information processing unit 22 sends the quantitative life index acquired in step S202 and the qualitative life index acquired in step S203 to a terminal device (not shown) operated by a third party. indicate.
Secondly, the sensor information processing unit 22 receives a third party's input of comments on the quantitative life index and the qualitative life index via a terminal device operated by the third party.
　ステップＳ２０５において、センサ情報処理部２２は、生活情報３１（図２）のレコードを作成する。具体的には、センサ情報処理部２２は、ステップＳ２０２、Ｓ２０３及びＳ２０４において受け付けたデータに基づき、午前０時００分００秒～１時００分００秒についてのレコードを作成する。ステップＳ２０５の直後に、センサ情報処理部２２は、ステップＳ２０４の処理を再度実行してもよい。例えば、１日２４時間が終了して初めて第三者が入力し得る第三者コメントもあり得るからである。 In step S205, the sensor information processing unit 22 creates a record of the life information 31 (Fig. 2). Specifically, the sensor information processing unit 22 creates a record for 00:00:00 to 1:00:00 based on the data received in steps S202, S203 and S204. Immediately after step S205, the sensor information processing unit 22 may perform the process of step S204 again. This is because, for example, there may be a third party comment that a third party can enter only after 24 hours in a day.
　ステップＳ２０２～Ｓ２０５は、１時間（６０分）ごとに繰り返される。その間、ステップＳ２０５を経由する都度、生活情報３１のレコードが時系列で蓄積されて行く。その間常時、センサ情報処理部２２は、生活情報３１の各レコードを監視し、ステップＳ２０１において受け付けた通知規則３２の生活変化（図３の欄１１２）が発生しているか否かを調べる。説明の便宜上、監視期間の開始時刻から約１週間が経過し、変化ＩＤ“Ｃ０１”（図３）が特定する生活変化が実際に発生したとする。 Steps S202 to S205 are repeated every hour (60 minutes). In the meantime, every time step S205 is passed, the records of life information 31 are accumulated in chronological order. During this time, the sensor information processing unit 22 constantly monitors each record of the lifestyle information 31 and checks whether or not the lifestyle change (column 112 in FIG. 3) of the notification rule 32 received in step S201 has occurred. For convenience of explanation, it is assumed that approximately one week has passed since the start time of the monitoring period, and the lifestyle change specified by the change ID “C01” (FIG. 3) has actually occurred.
　ステップＳ２０６において、センサ情報処理部２２は、生活変化を検知する。具体的には、センサ情報処理部２２は、生活情報３１（図２）の時系列のレコードのうちから、以下の〈１〉～〈３〉（ここでは論理積）を検知する。
〈１〉直近の５日間の平均値に比して、本日の活動量が１０％減少した。
〈２〉直近の５日間の平均値に比して、本日の外出回数が３０％減少した。
〈３〉直近の５日間の平均値に比して、本日の食事が１０％減少した。
　ここでの“平均値”は、“最大値”、“最小値”、“中央値”等に代替され得る。 In step S206, the sensor information processing unit 22 detects lifestyle changes. Specifically, the sensor information processing unit 22 detects the following <1> to <3> (logical product here) from the time-series records of the life information 31 (FIG. 2).
<1>Today's activity amount decreased by 10% compared to the average value for the last 5 days.
<2> The number of times I went out today decreased by 30% compared to the average value for the last 5 days.
<3>Today's meals decreased by 10% compared to the average value for the most recent 5 days.
The "average value" here may be replaced with "maximum value", "minimum value", "median value", and the like.
　図３の生活変化の１つとして“第三者コメントが「〇〇〇」の文字列を含む”が設定されている場合、センサ情報処理部２２は、第三者コメントに基づき、通知の必要性を判断していることになる。 When "a third party comment includes a character string of '000'" is set as one of the lifestyle changes in FIG. You are judging gender.
　ステップＳ２０７において、センサ情報処理部２２は、通知先及び通知内容を決定する。具体的には、センサ情報処理部２２は、〈１〉～〈３〉を検索キーとして通知規則３２（図３）を検索し、該当するレコードの通知先フラグ（欄１１５）及び通知内容（欄１１６）を取得する。取得された通知先フラグに“Ｐ”が添えられている場合もある。ここでは、通知先フラグとして、被見守り者に対する“○”が取得され、通知内容として、被見守り者に対する“生活変化” 及び“忠告”が取得される。 In step S207, the sensor information processing unit 22 determines the notification destination and notification content. Specifically, the sensor information processing unit 22 searches the notification rule 32 (FIG. 3) using <1> to <3> as search keys, and the notification destination flag (column 115) and notification content (column 116). "P" may be added to the acquired notification destination flag. Here, "○" for the watched person is acquired as the notification destination flag, and "life change" and "advice" for the watched person are acquired as the notification contents.
　ステップＳ２０８において、センサ情報処理部２２は、インセンティブを決定する。具体的には、第１に、センサ情報処理部２２は、〈１〉～〈３〉を検索キーとして通知規則３２（図３）を検索し、該当するレコードのインセンティブ（欄１１７）を取得する。ここでは、“－１０”が取得される。
　第２に、センサ情報処理部２２は、現時点のインセンティブの残高に対して“－１０”を加算する。 In step S208, the sensor information processing unit 22 determines incentives. Specifically, first, the sensor information processing unit 22 searches the notification rule 32 (FIG. 3) using <1> to <3> as search keys, and acquires the incentive (column 117) of the corresponding record. . Here, "-10" is acquired.
Second, the sensor information processing unit 22 adds "-10" to the current incentive balance.
　ステップＳ２０９において、センサ情報処理部２２は、通知を送信する。具体的には、センサ情報処理部２２は、被見守り者端末装置７に通知４１ａ（図５）を送信する。その後、処理手順を終了する。
　通知には、複数の種類が存在する。以降では、通知の表示例を説明する。 In step S209, the sensor information processing part 22 transmits a notification. Specifically, the sensor information processing unit 22 transmits a notification 41a (FIG. 5) to the terminal device 7 of the person being watched over. After that, the procedure ends.
There are multiple types of notifications. Hereinafter, display examples of notifications will be described.
　図５は、通知の一例を示す図である。図５の通知４１ａは、見守り装置１が変化“Ｃ０１”を検知した場合に、被見守り者端末装置７に送信される通知である。通知４１ａには、生活変化４２ａ、４２ｂ及び４２ｃ、並びに、忠告４３ａ、４３ｂ及び４３ｃが表示されている。生活変化４２ａ、４２ｂ及び４２ｃは、それぞれ忠告４３ａ、４３ｂ及び４３ｃに対応している。通知４１ａの下部には、変化ＩＤ、優先度及びポイント（前回比増減及び残高）が表示されている。被見守り者は、任意の方法で通知４１ａが着信したことを知り、任意の方法で通知４１ａを視認する。通知４１ａが見守り者端末装置３に送信される場合も同様である。 FIG. 5 is a diagram showing an example of notification. A notification 41a in FIG. 5 is a notification sent to the terminal device 7 of the person being watched when the watching device 1 detects the change "C01". Life changes 42a, 42b and 42c and advices 43a, 43b and 43c are displayed in the notification 41a. Life changes 42a, 42b and 42c correspond to recommendations 43a, 43b and 43c, respectively. At the bottom of the notification 41a, the change ID, priority and points (increase/decrease from the previous time and balance) are displayed. The person being watched knows that the notification 41a has arrived by any method, and visually recognizes the notification 41a by any method. The same applies when the notification 41a is sent to the watcher terminal device 3. FIG.
　図３における生活変化の１つが“第三者コメントが「〇〇〇」の文字列を含む”である場合、センサ情報処理部２２は、通知４１ａの任意の箇所に、第三者コメントを表示してもよい（図６～図９においても同様）。 If one of the lifestyle changes in FIG. 3 is "a third party comment includes a character string of '000'", the sensor information processing unit 22 displays the third party comment at an arbitrary location in the notification 41a. (The same applies to FIGS. 6 to 9).
　図６もまた、通知の一例を示す図である。図６の通知４１ｂは、見守り装置１が変化“Ｃ０２”を検知した場合に、被見守り者端末装置７に送信される通知である。図５に比して、図６の通知４１ｂが異なる点は、以下の通りである。
・優先度のレベルは、より大きくなっている。
・生活変化４２ｄ、４２ｅ及び４２ｆの減少割合は、より大きくなっている。
・忠告４３ｄ、４３ｅ及び４３ｆは、より大きな行動変容を促している。
・ポイント（前回比）の絶対値は、より大きい。 FIG. 6 is also a diagram showing an example of notification. A notification 41b in FIG. 6 is a notification sent to the watched person terminal device 7 when the watching device 1 detects the change "C02". The difference of the notification 41b in FIG. 6 from that in FIG. 5 is as follows.
• The level of priority is getting higher.
- The rate of decrease of life change 42d, 42e and 42f is larger.
• Advice 43d, 43e and 43f prompt greater behavioral change.
・The absolute value of the points (compared to the previous time) is larger.
　図７もまた、通知の一例を示す図である。図６の通知４１ｃは、見守り装置１が変化“Ｃ０４”を検知した場合に、見守り者端末装置３に送信される通知である。図５に比して、図７の通知４１ｃが異なる点は、以下の通りである。
・通知４１ｃには、プッシュマーク４４が表示されている。見守り装置１のセンサ情報処理部２２は、見守り者端末装置３に通知４１ｃを送信すると、見守り者端末装置３の出力装置（画面）に、プッシュマーク４４をアイコンとして強調表示する。見守り者がプッシュマーク４４を押下すると、センサ情報処理部２２は、通知４１ｃを見守り者端末装置３の出力装置（画面）に表示する。通知４１ｃが被見守り者端末装置７に送信される場合も同様である。 FIG. 7 is also a diagram showing an example of notification. A notification 41c in FIG. 6 is a notification transmitted to the watching person terminal device 3 when the watching device 1 detects the change "C04". The difference of the notification 41c in FIG. 7 from that in FIG. 5 is as follows.
- The push mark 44 is displayed on the notification 41c. When the sensor information processing unit 22 of the watching device 1 transmits the notification 41c to the watching person terminal device 3, the output device (screen) of the watching person terminal device 3 highlights the push mark 44 as an icon. When the watcher presses the push mark 44 , the sensor information processing unit 22 displays the notification 41 c on the output device (screen) of the watcher terminal device 3 . The same applies when the notification 41c is sent to the terminal device 7 of the person being watched.
・通知４１ｃには、“直近の健診データを見る”欄４５が表示されている。当該欄４５は、図３の“健診データ”（欄１１６）に対応する。見守り者が視認できる過去又は現在の健康診断結果として、ここでは４つの選択肢が表示されている。見守り者が、例えば“背筋力”を選択すると、見守り装置１のセンサ情報処理部２２は、背筋力に関する健康診断結果を見守り者端末装置３の出力装置（画面）に、時系列グラフで表示する（図示せず）。通知４１ｃが被見守り者端末装置７に送信される場合も同様である。過去の健康診断結果及び生活変化を同じ画面に表示することで、過去の健康診断結果が芳しくなかった機能（例えば歩行速度）が改善されたか否かを把握することができる。つまり、自身の過去の歩行速度との比較に加えて、過去の健康診断結果に対して改善されたか否かを把握できるため、被見守り者は、より運動をしようというモチベーションを高めることができる。 - The notification 41c includes a column 45 for "view latest health checkup data". The column 45 corresponds to "medical examination data" (column 116) in FIG. Here, four options are displayed as past or present health checkup results that can be visually recognized by the watcher. When the watcher selects, for example, "back muscle strength", the sensor information processing unit 22 of the watching device 1 displays the results of the health checkup related to back muscle strength on the output device (screen) of the watcher terminal device 3 as a time-series graph. (not shown). The same applies when the notification 41c is sent to the terminal device 7 of the person being watched. By displaying the past health checkup results and lifestyle changes on the same screen, it is possible to grasp whether or not a function (for example, walking speed) that was unsatisfactory in the past health checkup results has been improved. In other words, in addition to comparing one's own past walking speed, it is possible to grasp whether or not there has been an improvement with respect to past health checkup results, so that the person being watched can be motivated to exercise more.
・通知４１ｃには、“直近の生活情報を見る”欄４６が表示されている。当該欄４６は、図２の各指標（欄１０２ａ～１０２ｅ及び１０３ａ～１０３ｆ）に対応する。当該欄４６には、選択肢として、すべての量的生活指標及び質的生活指標が表示されている。なお、図６では、紙面の制約上、２つのみが表示されている。見守り者が、例えば“転倒回数”を選択すると、見守り装置１のセンサ情報処理部２２は、図２の転倒回数を見守り者端末装置３の出力装置（画面）に、時系列グラフで表示する（図示せず）。通知４１ｃが被見守り者端末装置７に送信される場合も同様である。 - In the notice 41c, a column 46 of "view recent living information" is displayed. The column 46 corresponds to each index (columns 102a to 102e and 103a to 103f) in FIG. This column 46 displays all quantitative and qualitative life indicators as options. Note that only two are shown in FIG. 6 due to space limitations. When the watcher selects, for example, "number of falls", the sensor information processing unit 22 of the watching device 1 displays the number of falls on the output device (screen) of the watcher terminal device 3 in FIG. not shown). The same applies when the notification 41c is sent to the terminal device 7 of the person being watched.
　図８もまた、通知の一例を示す図である。図８の通知４１ｄは、見守り装置１が変化“Ｃ１１”を検知した場合に、被見守り者端末装置７に送信される通知である。この場合、図３の方向は“改善”である。したがって、前記した忠告に代替して、激励４７ａ及び４７ｂが表示されている。通知４１ｄには、優先度は表示されない。通知４１ｄが見守り者端末装置３に送信される場合も同様である。 FIG. 8 is also a diagram showing an example of notification. A notification 41d in FIG. 8 is a notification transmitted to the watched person terminal device 7 when the watching device 1 detects the change "C11". In this case, the direction in FIG. 3 is "improve". Therefore, encouragement 47a and 47b are displayed instead of the above-mentioned advice. Priority is not displayed in the notification 41d. The same applies when the notification 41d is sent to the watcher terminal device 3. FIG.
　図９もまた、通知の一例を示す図である。図８の通知４１ｅは、見守り装置１が変化“Ｃ１２”を検知した場合に、見守り者端末装置３及び被見守り者端末装置７に送信される通知である。図６と同様、図８の通知４１ｅにも、プッシュマーク４４が表示されている。 FIG. 9 is also a diagram showing an example of notification. A notification 41e in FIG. 8 is a notification transmitted to the watching person terminal device 3 and the watched person terminal device 7 when the watching device 1 detects the change "C12". Similar to FIG. 6, the notification 41e in FIG. 8 also has a push mark 44 displayed thereon.
