Abstract
Description
本発明の適用例について説明する。従来技術では、測定対象の人物の画像を基に測定対象の人物を識別するため、測定対象の複数の人物が同じ寝具を使用する場合など、測定対象の人物の画像の違いが小さいために精度よく測定対象の各人物を識別できない可能性がある。また、従来技術では、測定対象の人物の位置によっては撮像装置で正しく測定対象の人物を撮像できず、正常に顔認証を行うことができない可能性がある。
本件開示の技術の一実施形態について説明する。本実施形態では、一例として、図1に示すように部屋10に生体情報処理装置100とベッド20が配置され、ベッド20に生体情報の測定対象である複数の人物31、32、33が横たわり、測定対象の各人物の睡眠時の呼吸に関する生体情報を生体情報処理装置によって取得する場合を想定する。ここでは、測定対象の人物31、32、33は1家族を構成し、それぞれ女性、子供、男性であると想定する。なお、ここでは、取得する生体情報は測定対象の人物の呼吸に関する生体情報を想定するが、取得する生体情報は、心拍や体動などに関する生体情報であってもよい。
次に、第2実施形態に係る生体情報処理装置について説明する。なお、以下の説明において、第1実施形態と同様の構成や処理などについては同一の符号を付し、詳細な説明は省略する。
次に、第3実施形態に係る生体情報処理装置について説明する。なお、以下の説明において、上記の実施形態と同様の構成や処理などについては同一の符号を付し、詳細な説明は省略する。
次に、第4実施形態に係る生体情報処理装置について説明する。なお、以下の説明において、上記の実施形態と同様の構成や処理などについては同一の符号を付し、詳細な説明は省略する。
次に、第5実施形態に係る生体情報処理装置について説明する。なお、以下の説明において、上記の実施形態と同様の構成や処理などについては同一の符号を付し、詳細な説明は省略する。
次に、第6実施形態に係る生体情報処理装置について説明する。なお、以下の説明において、上記の実施形態と同様の構成や処理などについては同一の符号を付し、詳細な説明は省略する。
上記の実施形態は、本発明の構成例を例示的に説明するものに過ぎない。本発明は上記の具体的な形態には限定されることはなく、その技術的思想の範囲内で種々の変形が可能である。以下に、上記の実施形態の変形例について説明する。なお、以下の説明において、上記の実施形態と同様の構成や処理については同一の符号を付し、詳細な説明は省略する。また、上記の各実施形態と以下に説明する変形例は、適宜組み合わせて実施することができる。
以下に変形例1に係る生体情報処理装置100について説明する。本変形例では、図8Aに示すように、ベッド20の代わりに圧力測定素子を設けたベッド200を用いる。図8Bに示すようにベッド200は、基部203の上に圧力測定素子群202とマットレス201が積層されて構成されている。圧力測定素子群202は、圧力測定素子が平面上に格子状に配置されて構成されており、これによりベッド200上の生体情報の測定対象の人物31、32、33の位置と各圧力測定素子の位置および圧力の大きさを示す信号が、生体情報処理装置100の送受信部111に送信される。したがって、受信部122は、測定対象の複数の人物によってそれぞれ異なる位置に加えられる圧力を示す信号を受信することができる。
次に、変形例2に係る生体情報処理装置100について説明する。上記の実施形態において、例えば、生体情報の測定対象の人物が腰や背中を曲げているなど測定対象の人物の位置や姿勢が生体情報の取得には適切でない場合や、反射体が適切に装着されていないために候補領域を適切に特定できない場合など、測定対象の人物と生体情報との対応関係を特定するにあたって不適切な状況が生じる可能性がある。そこで、本変形例では、このような不適切な状況が生じた場合にユーザにエラーとして通知することができる。
以下に変形例3に係る生体情報処理装置100について説明する。本変形例では、一例として、図1に示す第1実施形態と同様に、部屋10に生体情報処理装置100とベッド20が配置され、ベッド20に生体情報の測定対象である複数の人物31、32、33が横たわり、測定対象の各人物の睡眠時の呼吸に関する生体情報を生体情報処理装置によって取得する場合を想定する。
