Description

本発明は、使用者の咀嚼状態を認識する咀嚼状態認識装置に関する。   The present invention relates to a mastication state recognition device for recognizing a user's mastication state.

適切な咀嚼運動は、食物を細かく砕いて消化管による消化を助長する、上下頬骨の発育を促し、顎や脳への血流を促進する、消化吸収を緩慢にして食後に生ずる反応性の低血糖を防止し、食事量を抑制するなど、様々な面から健康に有益である。そのため、咀嚼回数を多くすることが奨励されているが、これを支援する技術も提案されており、例えば特許文献1には咀嚼回数を増やすための咀嚼回数検出装置が開示されている。   Appropriate chewing exercises break up food to promote digestion by the digestive tract, promote the development of the upper and lower cheekbones, promote blood flow to the jaw and brain, slow digestion absorption, and less reactive after meals It is beneficial to health from various aspects, such as preventing blood sugar and suppressing food consumption. For this reason, it is encouraged to increase the number of mastications, but a technology for supporting this has also been proposed. For example, Patent Document 1 discloses a mastication number detection device for increasing the number of mastications.

特許文献1の咀嚼回数検出装置は、咀嚼による顎関節等の動きを外耳孔等の軟組織を介して検知する検知部を外耳孔等に取り付け、検知部の検知結果に基づいて咀嚼運動を検出する咀嚼運動検出部を設け、前記検知部を、咀嚼による顎関節等の動きに応じた外耳孔等の軟組織の変位に応じて弾性変形する弾性部材と、前記弾性部材の変形を検出するトランスデューサーとを有する構成とし、前記トランスデューサーを圧力センサ、圧電素子、或いはスイッチとするものであり、容易な咀嚼回数の検出や小型化が可能である。   The mastication frequency detection device of Patent Literature 1 attaches a detection unit that detects movement of a temporomandibular joint or the like by mastication through a soft tissue such as an outer ear canal to detect the mastication motion based on the detection result of the detection unit. A mastication motion detection unit is provided, and an elastic member that elastically deforms the detection unit according to displacement of a soft tissue such as an outer ear hole according to movement of a temporomandibular joint or the like by mastication, and a transducer that detects deformation of the elastic member The transducer is a pressure sensor, a piezoelectric element, or a switch, so that the number of mastication times can be easily detected and the size can be reduced.

In addition, an interval at which the peaks of the detected waveform appear, for example, successive peaks where the peaks appear at a peak within an allowable interval is recognized, and the number of recognized peaks is counted.

出力制御部125は、ROM等に記憶された制御プログラムに従って処理を行うCPUやワーキングメモリ等で構成され、許容個数記憶部126、出力データ記憶部127は、ハードディスク等で構成されており、出力制御部125は、咀嚼動作検出部124で認識された山部の個数が設定個数記憶部126の設定個数未満である場合に、出力データ記憶部127に設定個数未満の場合に対応して記憶されている異常咀嚼情報を抽出し、スピーカ14から異常咀嚼情報を報知する。また、出力制御部125は、咀嚼動作検出部124で認識された山部の個数が設定個数記憶部126の設定個数以上である場合に、出力データ記憶部127に許容個数以上の場合に対応して記憶されている正常咀嚼情報を抽出し、スピーカ14から報知する、或いは許容個数以上である場合に特に出力を行わない。また、タイマー128は、時刻計測を行い、計測した時刻或いは時間が検知波形取得部121など所定の処理部によって使用される。   The output control unit 125 is configured by a CPU, a working memory, or the like that performs processing according to a control program stored in a ROM or the like. The allowable number storage unit 126 and the output data storage unit 127 are configured by a hard disk or the like, and output control is performed. The unit 125 is stored in the output data storage unit 127 corresponding to the case where the number of peaks recognized by the mastication motion detection unit 124 is less than the set number in the set number storage unit 126. The abnormal mastication information is extracted, and the abnormal mastication information is notified from the speaker 14. Further, the output control unit 125 corresponds to the case where the number of peaks recognized by the mastication motion detection unit 124 is equal to or greater than the set number in the set number storage unit 126 and the output data storage unit 127 exceeds the allowable number. The normal mastication information stored in the above is extracted and notified from the speaker 14, or no output is performed when the number is greater than the allowable number. The timer 128 measures time, and the measured time or time is used by a predetermined processing unit such as the detection waveform acquisition unit 121.

第1実施形態の咀嚼状態認識装置10で咀嚼状態を認識する際には、使用者は、咀嚼状態認識装置10を左右の何れかの耳に挿入して取り付け、検知部15を外耳道の内壁に当接或いは近接して配置し、咀嚼状態認識装置10のスイッチ18をON状態にして食事する。検知部15は、使用者の食事による外耳道の変形に伴って外耳道の変形量を取得し、検知波形取得部121は、検知部15が検知する外耳道の変形量を時系列的に取得し、この変形量に対応する検知波形を取得する。   When recognizing the mastication state with the mastication state recognition device 10 of the first embodiment, the user inserts and attaches the mastication state recognition device 10 to either the left or right ear and attaches the detection unit 15 to the inner wall of the ear canal. It arrange | positions in contact | abutting or adjoining, the switch 18 of the mastication state recognition apparatus 10 is turned on, and it eats. The detection unit 15 acquires the amount of deformation of the ear canal according to the deformation of the ear canal due to the user's meal, and the detection waveform acquisition unit 121 acquires the amount of deformation of the ear canal detected by the detection unit 15 in time series. A detection waveform corresponding to the deformation amount is acquired.

そして、咀嚼動作検出部124は、取得した検知波形から、検知波形の山部のピークの変形量(図3のα)が許容変形量以内で、且つ検知波形の山部の出現する時間の間隔、例えば山部のピークの出現する間隔(図3のβ)が許容間隔以内である連続する山部を認識し、認識した山部の個数をカウントする。カウントした山部の個数が設定個数未満である場合には、出力制御部125は、咀嚼回数に関する異常咀嚼情報を抽出してスピーカ14から報知し、カウントした山部の個数が設定個数以上である場合には、出力制御部125は、咀嚼回数に関する正常咀嚼情報を抽出してスピーカ14から報知する。   Then, the mastication operation detection unit 124 determines from the acquired detection waveform that the peak deformation amount (α in FIG. 3) of the detection waveform is within the allowable deformation amount and the time interval at which the detection waveform peak appears. For example, continuous peaks that have peak intervals (β in FIG. 3) within the allowable interval are recognized, and the number of recognized peaks is counted. If the counted number of ridges is less than the set number, the output control unit 125 extracts abnormal mastication information related to the number of mastications and notifies it from the speaker 14, and the number of counted ridges is greater than or equal to the set number. In this case, the output control unit 125 extracts normal mastication information related to the number of mastications and notifies the speaker 14 of it.

第1実施形態の咀嚼状態認識装置10は、ピークの変形量が許容変形量以内で、且つ出現する間隔が許容間隔以内である連続する検知波形の山部を認識し、山部の個数をカウントすることにより、咀嚼時と発話時に検出される検知波形を区別して咀嚼動作を正確に検出し、会話しながらの食事の際にも咀嚼回数を正確に認識することができる。また、本体等に外耳道へ抜ける孔部を設け、スピーカから孔部を介して咀嚼状態情報を報知することにより、使用者は通常の食事動作を維持しつつ、咀嚼状態の情報を認識することができると共に、外部に咀嚼状態の情報が報知されることを防止することができる。また、一方の耳だけに咀嚼状態認識装置10を取り付ければよいので、使用者の良好な聴力を確保することができる。   The mastication state recognition apparatus 10 according to the first embodiment recognizes a peak portion of a continuous detection waveform in which the peak deformation amount is within the allowable deformation amount and the appearing interval is within the allowable interval, and counts the number of peak portions. By doing so, it is possible to accurately detect the mastication operation by distinguishing the detection waveforms detected during mastication and utterance, and to accurately recognize the number of mastications during meals while talking. In addition, by providing a hole in the main body or the like through the ear canal and notifying the mastication state information from the speaker through the hole, the user can recognize the information on the mastication state while maintaining a normal eating operation. While being able to do, it can prevent that the information of a mastication state is alert | reported outside. Moreover, since the mastication state recognizing device 10 only needs to be attached to one ear, the user's good hearing ability can be ensured.
