- the power supply unit 320 has a function of supplying power to each unit of the animal emotion estimation apparatus 1.
- the power supply unit 320 is realized by a so-called lithium ion battery, an alkaline battery, a manganese battery, or the like.
- the noise signal with noise as shown in FIG. 5 (a) is converted into a heartbeat signal as shown in FIG. 5 (b).

The control unit also has a function of transmitting a face image based on the estimated animal emotion to the communication unit 340.
- the controller 330 Based on the heartbeat signal transmitted from the sensor processing circuit 310, the controller 330 estimates the emotion of the animal by performing heartbeat variability analysis (HRV analysis: Heart Rate Variation analysis).
- HRV analysis Heart Rate Variation analysis
- NN50 in HRV analysis that is generally well known. This is the RR interval (beat-to-beat interval) of a fixed number of samples (for example, 60 or a heart rate during a fixed time (for example, 1 minute)), and the section HI in FIG.
- the number of times (NN50) at which the difference between the RR intervals is continuously observed to be 50 ms or more (NN50) is counted.
- This is a technique for determining whether or not the sympathetic nerve is active based on the value of pNN50 obtained by dividing NN50 by the number of samples in the RR interval. If pNN50 is low, it is determined that the sympathetic nerve is active (stress is felt). However, since the value of 50 ms here applies to humankind, it cannot be applied to animals as it is.
- control unit 330 of the animal emotion estimation apparatus 1 first converts the time of 50 ms in the case of a human being to the time Xms for animals.
- the control unit 330 calculates the average RR interval from the acquired heartbeat signal and multiplies the above-mentioned ratio 6.7% to obtain the animal time Xms. Therefore, in the case of this animal, whether or not the sympathetic nerve is active is determined based on the number of times that it is continuously observed that the RR interval of a certain number of samples is 67 ms or more.
- the control unit 330 periodically calculates the pNNX time, and determines whether the sympathetic nerve is active based on the calculated pNNX time. Thereby, the control unit 330 can determine whether or not the animal wearing the animal emotion estimation apparatus 1 feels stress. In addition, the control unit 330 estimates the emotion of the animal also by the Poincare plot analysis.
- the RR interval time is taken on the X axis and the Y axis.
- the RR interval at time t1 is T1
- the RR interval at time t2 is T2
- the RR interval at time t3 is T3
- the RR interval at time t4 is T4 (t1 ⁇ t2 ⁇ t3 ⁇ t4).
- points having two consecutive RR intervals as the X coordinate and the Y coordinate are plotted. That is, a point P n ⁇ 2 can be plotted with the RR interval T2 at time t2 as the X coordinate and the RR interval T3 at time t1 as the Y coordinate.
- a point is plotted with the newer RR interval as the X coordinate and the previous RR interval as the Y coordinate.
- the control unit 330 performs an analysis based on the distance between the two points plotted in this way and the angle ⁇ (see FIG. 9) formed by the three points.
- the control unit 330 divides the linear distance between two points by a certain parameter to normalize in order to qualitatively determine the linear distance regardless of whether the heart rate is high or low.
- the parameter is desirably a value that becomes relatively smaller as the heart rate becomes higher.
- the longer total value of the two X-coordinate and Y-coordinate values is used.
- control unit 330 performs emotion estimation based on an angle ⁇ formed by a straight line formed by two consecutively plotted points and a straight line formed by a point continuous with one of the two points on the Poincare plane. Execute. That is, in the example of FIG. 9, the emotion estimation based on the angle ⁇ formed by the straight line connecting the point P n-2 and the point P n-1 and the straight line connecting the point P n-1 and the point P n is performed. Do.
- control unit 330 calculates the angle ⁇ obtained based on the four points plotted on the Poincare plane, and determines whether or not the user feels stress according to the angle.
- control unit 330 determines whether or not the heart rate per unit time is below a certain value based on the heartbeat signal. When the state where the heart rate is equal to or less than a certain value continues for a certain period of time, the control unit 330 determines that the animal feels sleepy. In addition, when it is judged that there is drowsiness, the control part 330 will judge only that there is drowsiness whatever the state of other stress levels and interest levels.
- the controller 330 estimates the emotion of the animal by performing HRV analysis based on the heartbeat signal obtained from the sensor 100 as described above.
- the communication unit 340 has a function of wirelessly communicating with a mobile terminal such as a user's smart phone, and transmits information transmitted from the control unit 330 to the user's mobile terminal according to a predetermined communication protocol.

Abstract
Description
以下、本発明に係る動物感情推定装置の一実施態様について、図面を参照しながら、詳細に説明する。
本発明に係る動物感情推定装置は、動物の大まかな感情を推定し、飼い主等のユーザに、動物が何を考えているかを示すおおよその感情を提示する。動物感情推定装置1は、図1(a)に示すように、動物(図1では犬)に装着して用いる。動物感情推定装置1は、装着した動物の心拍音を図1(b)に示すセンサー(集音器)100で集音し、得られた心拍音を示す心拍信号に基づいて装着した動物の感情を推定する。そして、動物感情推定装置1は、図1(b)に示す、動物感情推定装置1に設けられた出力部200に動物のその時々の感情を示す顔を表示する。これにより、ユーザは動物がどのような感情を抱いているのかを認識することができる。
以下、本発明に係る動物感情推定装置1について詳細に説明する。
図1(a)、図1(b)に示すように、動物感情推定装置1は、対象となる動物に着装できるように構成されており、動物用のハーネスに、センサー100と、出力部200を含む制御装置が固着されてなる。なお、図1においては、犬に装着する例を示しているが、犬以外の動物に装着して用いてもよいことは言うまでもない。
図1(b)に示すように、センサー100と出力部200とは、接続線110を介して接続され、センサー100により集音された音声信号が伝達される。
図2は、センサー100の構成を示す図である。
図2(a)は、センサー100の斜視図であり、図2(b)は、図2(a)におけるセンサー100をA-A’線で切断した場合の断面図である。
台部102は、樹脂などの弾性部材から成り、図2(a)、図2(b)に示されるように、パラボラ状(すり鉢状、漏斗状)の凹部を有する。なお、ここでは軽量化を考慮して台部として樹脂を用いることとしているが、硬質な部材であってもよく、音波の反射率の高い素材を用いるとよい。
そして、当該凹部の底部に、マイクロフォン101が設けられ、接続線110がスポンジ103の外部に導出される。
図3は、動物感情推定装置1の機能構成を示す機能ブロック図である。
また、制御部330は、ポワンカレプロット解析によっても、動物の感情の推定を行う。
図6は、動物感情推定装置1に記憶されている動物の状態に応じて表示すべき顔画像を示す顔画像表600のデータ概念図である。
図7は、動物感情推定装置1の動作を示すフローチャートである。
図7に示すように、動物感情推定装置1のセンサー100は、動物の生体情報を取得する(ステップS701)。本実施の形態においては、動物感情推定装置1は、マイクロフォン101から心拍音を含む音声信号を取得する。
上記実施の形態に示したように、実施の形態に係る動物感情推定装置1は、動物に着装されて、その心音を示す音声信号を取得する。そして、その音声信号に基づく心拍を特定し、その心拍に基づいて動物の感情を推定し、その感情を示す情報を出力することができる。したがって、ユーザは、その出力された情報を見て、動物がどのような感情を抱いているのかを一目に認識することができる。また、動物感情推定装置1は、センサー100として、その外部をスポンジ剤で覆うことにより、柔軟に変化する動物の皮膚との密着状態を維持でき、効率よく、適格に心音を取得することができる。
本実施の形態2に係る動物感情推定装置は、上記実施の形態1に示した場合とは異なり、出力部200は、顔画像を表示するではなく、発光する。そして、その発光色や、発光の仕方により、動物感情推定装置は、推定した動物の感情を表現する。以下、本実施の形態2に係る動物感情推定装置10について説明する。
図10は、本実施の形態2に係る動物感情推定装置10を動物(図10の例では犬)が装着した状態を示す図である。また、図11は、動物感情推定装置10の外観斜視図であって、(a)、(b)はそれぞれ異なる角度から見た動物感情推定装置10の外観を示している。
図14は、本実施の形態に係る動物感情推定装置10が保持する基本色決定表1400のデータ構成例を示すデータ概念図である。
図15は、本実施の形態2に係る動物感情推定装置10の動作を示すフローチャートである。
本実施の形態2に係る動物感情推定装置10によれば、LEDの発光色や、発光強度(輝度)、発光タイミング(明滅の周期の遅い早い)によって、動物の感情を表現することができる。ユーザは、その発光を見て動物がどのような感情を抱いているのかを推定することが容易になる。例えば、青や緑で比較的穏やかに明滅していると、落ち着いて心安らかなのだろうと推定したり、赤や黄で比較的早く明滅していると、興奮しながらも集中しているのだろうと推定したりすることができる。
上記実施の形態に本発明に係る発明の一実施態様を説明したが、本発明に係る思想がこれに限られないことは言うまでもない。以下、本発明に係る思想として含まれる各種変形例について説明する。
(3)上記実施の形態においては、動物の感情を表現する手法として、出力部200に感情を示す顔画像を表示することとしたが、これはその限りではない。
そして、動物感情推定装置1の装着具に図8(b)に示すように設ける。
ここで、本発明に係る集音器、動物感情推定装置及び動物感情推定方法について、その一実施態様と、当該態様により奏する効果を説明する。
これにより、動物の感情を色で表現できる。したがって、ユーザは、動物の気分をある程度認識でき、意志疎通がしやすくなる。例えば、怒っていれば赤に点灯したり、のんびりしたり眠いときは緑に点灯したりすることで、動物感情推定装置は、動物の感情をユーザが認識できるようにすることができる。
