Fig. 1 is a schematic diagram illustrating a connection structure of a single-sided mastication monitoring device 100 according to an embodiment of the present application, including: a first transceiver 110, a second transceiver 120, and a processor 130.
The first transceiver 110 is configured to transmit at least one wireless signal to the left masticatory muscle for a period of time, receive at least one left reflected wave reflected by the left masticatory muscle, and send the received left reflected wave to the processor 130. In one possible embodiment, the first transceiver 110 is, for example, a wireless device that transmits and receives a wireless signal of a fixed frequency, i.e., a left-side reflected wave, to the left-side masticatory muscle at a certain time interval t. Of course, those skilled in the art should understand that the description is only illustrative and should not be construed as limiting the embodiments of the present application.
The second transceiver 120 is configured to transmit at least one wireless signal to the right masticatory muscle during the time period, receive at least one right reflected wave reflected by the right masticatory muscle, and send the received right reflected wave to the processor 130. In one possible embodiment, the second transceiver 120 is, for example, a wireless device, which transmits and receives a wireless signal with a fixed frequency, i.e., a right-side reflected wave, to the right-side masticatory muscle at a certain time interval t. Of course, those skilled in the art should understand that the description is only illustrative and should not be construed as limiting the embodiments of the present application.
The processor 130 is configured to obtain a left-side reflected wave transmitted by the first transceiver 110 during the time period, obtain a left-side spectral width value according to the left-side reflected wave, obtain a right-side reflected wave transmitted by the second transceiver 120 during the time period, and obtain a right-side spectral width value according to the right-side reflected wave; and, whether the time period is one-sided chewing is judged according to the left side spectrum width value and the right side spectrum width value.
The inventor of the present application has found that when a user chews with the left masticatory muscle, the amplitude of the motion of the left masticatory muscle is greater than the amplitude of the motion of the right masticatory muscle, resulting in a spectral width H of the reflected wave on the leftleftGreater than the spectral width H of the reflected wave on the rightright(ii) a When the user chews with the right masticatory muscle, the action amplitude of the right masticatory muscle is larger than that of the left masticatory muscle, resulting in a spectral width value H of the reflected wave on the right siderightGreater than the spectral width H of the left-hand reflected waveleft(ii) a Similarly, the user chews with the left and right masticatory muscles, with the amplitude of the motion of the left masticatory muscle equal to or nearly equal to the amplitude of the motion of the right masticatory muscle, resulting in a spectral width value H of the reflected wave on the leftleftEqual or almost equal to the spectral width value H of the right-hand reflected waveright. Therefore, the spectral width value H is determined according to the left-side reflected waveleftThe spectral width value H of the reflected wave on the right siderightThe relationship between the sizes of (a) and (b) can be judged as left-side chewing or right-side chewing, or non-single-side chewing or double-side chewing.
Specifically, the processor 130 calculates the spectral width H according to the left reflected waveleftGreater than the spectral width H of the reflected wave on the rightrightJudging to be chewing on the left side; or according to the spectral width value H of the right reflected waverightGreater than the spectral width H of the left-hand reflected waveleftJudging to be chewing on the right side; or according to the spectral width H of the left-side reflected waveleftEqual or almost equal to the spectral width value H of the right-hand reflected waverightIt is judged to be either double-chewed or non-single-chewed.
Fig. 2 is a schematic diagram showing a spectrum curve of a left-side reflected wave and a spectrum curve of a right-side reflected wave, wherein an abscissa X is a spectrum, an ordinate Y is a power spectrum density, a curve 21 is a spectrum curve of the left-side reflected wave, and a curve 22 is a spectrum curve of the right-side reflected wave. It can be seen that the spectral width value H of the curve 21leftSpectral width value H greater than curve 22rightThe graph shows that the user chews one-sided and uses the left-sided to chew.
In the present embodiment, the spectral width value of the left-side reflected wave and the spectral width value of the right-side reflected wave reflect the left-side mastication condition and the right-side mastication condition, respectively, and therefore, it is possible to determine whether or not one-side mastication is performed based on the spectral width value of the left-side reflected wave and the spectral width value of the right-side reflected wave.
In one possible embodiment, the processor 130 obtains the left spectral width value H according to the left reflected waveleftAcquiring a right spectral width value H according to the right reflected waverightThen; the left side spectrum width value HleftAnd right spectral width value HrightDifference of (d) and a spectral width threshold HthComparing, and obtaining the left-side spectrum width value HleftAnd right spectral width value HrightIs greater than or equal to the spectral width threshold HthWhen (i.e. | H)left－Hright|≥Hth) Judging that the chewing side is the one-sided chewing side and judging that the frequency spectrum width value is large; otherwise, it may be determined to be a non-unilateral chew. The spectral width threshold HthThe setting may be made according to circumstances.
In one possible implementation, the processor 130 obtains the chewing time lengths of the single-sided chewing in a plurality of time periods, obtains a cumulative time length of the left-sided chewing and a cumulative time length of the right-sided chewing, obtains a difference value between the cumulative time length of the left-sided chewing and the cumulative time length of the right-sided chewing, and determines whether the plurality of time periods are the single-sided chewing according to at least an absolute value of the difference value and a time length difference threshold. The duration difference threshold may be set according to circumstances.
Specifically, the absolute value of the difference between the cumulative duration of the left chewing and the cumulative duration of the right chewing is greater than or equal to the duration difference threshold, and the left chewing is judged to be unilateral chewing; for the one-sided chewing situation, when the cumulative duration of the left-sided chewing is longer than the cumulative duration of the right-sided chewing, the left-sided chewing is judged; and when the cumulative duration of the left-side chewing is less than the cumulative duration of the right-side chewing, judging the right-side chewing. And if the absolute value of the difference between the cumulative duration of the left chewing and the cumulative duration of the right chewing is less than the duration difference threshold, judging the double-sided chewing.
For example, for n (n is a natural number) chewing time periods, the 1 st, 2 nd and 3 rd segments … … nth segments, respectively, the chewing time length of each chewing time period is obtained, and the n chewing time lengths are accumulated to obtain the accumulated time length T. Then, the cumulative duration T of left-side chewing in the n chewing time periods is obtainedleftAnd the cumulative length of time T of right side chewingrightAnd obtaining the cumulative length of time T of left side chewingleftCumulative length of time to chew on the rightrightThe absolute value of the difference with a time length difference threshold TthBy comparison, the cumulative length of time T when chewing on the leftleftCumulative length of time to chew on the rightrightIs greater than or equal to the duration difference threshold TthTime (i.e. | T)left－Tright|≥Tth) Judging that the patient chews on one side in the n time periods, and judging that the accumulated time length is larger as a chewing side; otherwise, it is judged to be not one-sided chewing. The way of recording the length of time is for example to calculate the length of time chewed from the start chewing time and the end chewing time. Of course, the person skilled in the art may also calculate the chewing time in other ways, which are only used for illustration and should not be construed as limiting the scope of the present application.
The processor 130 may be disposed on a wearable device, such as smart glasses, earphones, and the like. The processor 130 may communicate with the first transceiver 110 and the second transceiver 120 via bluetooth, infrared, etc. Of course, those skilled in the art should understand that this is by way of example only and should not be construed as limiting the present application. Other ways of communicating with each other are also within the scope of the present application.
In the present embodiment, if the absolute value of the difference between the cumulative time length of left-side chewing and the cumulative time length of right-side chewing is greater than the time length difference threshold, it indicates that the user chews with one side for a longer time. Thus, it is possible to automatically monitor whether unilateral chewing is performed.
Fig. 3 is a schematic diagram illustrating a connection structure of a monitoring device 300 according to another embodiment of the present application, where the monitoring device 300 may further include: and a prompter 340 for performing one-sided mastication prompting according to the result of the one-sided mastication determined by the processor 130.
The processor 130 determines that the user chews on one side, and sends a trigger signal for chewing on one side to the prompter 340, and the prompter 340 prompts chewing on one side according to the trigger signal. For example, if the absolute value of the difference between the cumulative duration of the left-side chewing and the cumulative duration of the right-side chewing is greater than the duration difference threshold, and the cumulative duration of the left-side chewing is greater than the cumulative duration of the right-side chewing, which indicates that most of the time is left-side chewing, the user may be prompted to chew on the left-side for a long time, or the user may be prompted to need to chew on the right-side, or the user may be prompted to refer to the cumulative duration of the left-side chewing and the cumulative duration of the right. Similarly, a one-sided chew prompt may be made for situations where the user is using a right-sided chew.
In one possible embodiment, the prompting device 340 is one, that is, the processor 130 sends a trigger signal of one-sided chewing to the prompting device 340, and the prompting device 340 prompts according to the trigger signal, so that the user can know that the user has used one-sided chewing for a long time before and adjust the chewing side according to the one-sided chewing.
In another possible embodiment, the prompter 340 may include a left prompter and a right prompter, and for the case of determining to chew on the left, the processor 130 may send a trigger signal for one-sided chewing to the left prompter, and the left prompter prompts according to the trigger signal, so that the user knows to chew on the left for a long time before himself, and accordingly adjusts to chew on the right; similarly, in the case of determining to chew on the right side, the processor 130 may send a trigger signal for one-sided chewing to the right prompter, and the right prompter prompts according to the trigger signal so that the user knows to chew on the right side for a long time before using the right side, and accordingly adjusts to chew on the left side. Of course, those skilled in the art will appreciate that the description herein is by way of example only, and should not be construed as limiting the embodiments of the present application. For example, when the user uses left-side chewing for a long time, the processor 130 may also send a trigger signal to the right-side prompter, which prompts the user to use the right-side to chew according to the trigger signal.
The prompter 340 may be disposed on a wearable device, such as smart glasses, earphones, or a mobile terminal. The prompter 340 may be an indicator light, an alarm, or a spectacle lens of smart glasses, etc.
One possible implementation mode is that an indicator light or an alarm is arranged on the left side or the right side of the intelligent glasses respectively, the left side is chewed when the user uses the left side for a long time, the indicator light on the left side is flickered to remind the user, or the alarm is used for giving an alarm. The prompter 340 can be arranged on the left side glasses frame or the right side glasses frame of the intelligent glasses; or on the left or right side of the temple.
In one possible embodiment, the subtitle content is displayed on the smart glasses, that is, the display screen of the smart glasses is used as the prompter 340, the processor 130 sends a prompt message of the result of one-sided chewing to the smart glasses, for example, left-sided chewing is used for a long time, the prompt message is displayed on the glasses of the smart glasses, and the user can adjust the chewing side according to the prompt message.
One possible implementation mode is that an indicator light or an alarm is respectively arranged on the left side or the right side of the earphone, and for the user to chew on the left side for a long time, the indicator light on the left side is used for flashing reminding, or the alarm is used for giving an alarm. The left side is for example the left earpiece of the headset and the right side is for example the right earpiece of the headset.
In one possible implementation, the reminder 340 is disposed in the mobile terminal. When the processor 130 determines that the user chews one-sided, it sends a trigger signal for one-sided chewing to the mobile terminal, and the mobile terminal prompts one-sided chewing according to the trigger signal by at least one of sound prompt, indicator lamp flashing, alarm sound, caption content display, and the like.
In this embodiment, a single-sided chewing prompt is given according to the result of determining that the user chews one-sided, and the user can be recommended to chew one-sided with a small accumulated time length, thereby reminding the user to chew uniformly.
Fig. 4 is a schematic layout diagram of the first transceiver and the second transceiver in the monitoring device shown in fig. 3. The first transceiver 110 and the second transceiver 120 are wireless devices and are respectively disposed below the left frame 401 and the right frame 402 of the smart glasses 400, and the processor and the prompter are both disposed on the smart glasses 400 (for example, disposed on the frame of the smart glasses 400 and connected to the first transceiver 110 and the second transceiver 120 by a circuit), so the layout of fig. 4 is repeated to show the layout of the first transceiver 110 and the second transceiver 120, and the processor and the prompter are not shown in detail. It should be understood by those skilled in the art that the present embodiment is illustrative only and should not be construed as limiting the scope of the present application.
Specifically, the first transceiver 110 is disposed below the left frame 401 of the smart glasses 400, and transmits and receives a wireless signal of a fixed frequency, i.e., a left reflected wave, to the left masticatory muscle (see the area indicated by the dashed circle 403 in the figure) at a predetermined time interval t. Since the first transceiver 110 is disposed below the left frame 401, when the user wears the smart glasses 400, the first transceiver 110 is located above the left masticatory muscle 403, and during the chewing process of the user, the first transceiver 110 transmits a wireless signal to the left masticatory muscle 403 at a certain time interval t, i.e., receives a left reflected wave reflected by the left masticatory muscle 403 at a fixed frequency, and transmits the received left reflected wave to the processor. Of course, the first transceiver 110 may be disposed at the side of the left frame 401 or at any other position as long as it can transmit and receive the left reflected wave reflected by the left masticatory muscle 403.
The second transceiver 120 is disposed under the right frame 402 of the smart glasses 400, and transmits and receives a radio signal of a fixed frequency, i.e., a right reflected wave, to the right masticatory muscle (see the area portion indicated by the dashed line 404 in the figure) at a time interval t. Since the second transceiver 120 is disposed below the right frame 402, when the user wears the smart glasses 400, the second transceiver 120 is located above the right masticatory muscle 404, and during the chewing process of the user, the second transceiver 120 transmits a wireless signal to the right masticatory muscle 404 at a predetermined time interval t, so as to receive the right reflected wave reflected by the right masticatory muscle 404 at a predetermined frequency, and then transmits the received right reflected wave to the processor. Of course, the second transceiver 120 may be disposed at the side of the right frame 402 or at any other position as long as it can transmit and receive the right reflected wave reflected by the right masticatory muscle 404.
The processor is arranged in the intelligent glasses, obtains the frequency spectrum width value of the left reflected wave and the frequency spectrum width value of the right reflected wave in a time period, and judges whether to chew on one side or not according to the two frequency spectrum width values. For example, according to the fact that the frequency spectrum width value of the left reflected wave is larger than that of the right reflected wave, one-sided chewing in the time period is judged, left-sided chewing time length is recorded, and left-sided chewing accumulated time length in n chewing time periods is obtained. And similarly, acquiring the right chewing accumulated time length in the n chewing time periods. For example, if the cumulative length of time of left-side chewing is 3 hours, the cumulative length of time of right-side chewing is 1 hour, and the length difference threshold is 30 minutes, then the absolute value of the difference between the cumulative length of time of left-side chewing and the cumulative length of time of right-side chewing is 2 hours, which is greater than the length difference threshold by 30 minutes, indicating that the left-side chewing is used for a longer time.
After the left side is chewed, the processor sends prompt information to a left side prompter arranged on a left side frame of the intelligent glasses, the left side prompter is triggered to remind that the left side is used for a long time to chew, and the left side prompter is an indicator lamp or an alarm. Or, the processor sends prompt information to a right prompter arranged on a right side frame of the intelligent glasses, the right prompter is triggered to remind of 'please use the right side to chew', and the right prompter is an indicator lamp or an alarm for example. Alternatively, the subtitle content may be displayed on glasses of the smart glasses, that is, the glasses are used as a prompter, and the processor sends a prompt message to the prompter, so that the prompt message is displayed on the glasses, for example, "use left side chewing for a long time", or "please use right side to chew", or the cumulative duration of left side chewing and the cumulative duration of right side chewing are displayed on the glasses.
This embodiment sets up monitoring facilities in intelligent glasses, can conveniently accomplish unilateral monitoring and the suggestion of chewing through intelligent glasses.
Fig. 5 is a schematic diagram illustrating a connection structure of a monitoring device 500 according to another embodiment of the present invention, including: a first module 510, a second module 520, and a processing module 530.
The first module 510 is configured to obtain at least one left reflected wave reflected by the left masticatory muscle for a period of time, and send the obtained left reflected wave to the processing module 530; the second module 520 is configured to obtain at least one right-side reflected wave reflected by the right masticatory muscle within the time period, and send the obtained right-side reflected wave to the processing module 530; the processing module 530 obtains a left-side spectral width value from the left-side reflected wave, obtains a right-side spectral width value from the right-side reflected wave, and determines whether the time period is one-sided chewing according to at least the left-side spectral width value and the right-side spectral width value. The first module 510, the second module 520, and the processing module 530 may be disposed on a wearable device, such as smart glasses, a headset, and the like.
The first module 510 and the second module 520 may be implemented by a transceiver, for example, and the processing module 530 may be implemented by a calculator and a comparator, for example, the calculator obtains a left-side spectrum width value according to the left-side reflected wave and obtains a right-side spectrum width value according to the right-side reflected wave, and respectively outputs the left-side spectrum width value and the right-side spectrum width value to two input terminals of the comparator, and the comparator compares the two values and outputs a signal indicating a comparison result. For example, if the left-side spectral width value is larger than the right-side spectral width value, a high-level signal is output, otherwise, a low-level signal is output. In another embodiment, if a prompting module is further connected, the high-level or low-level signal is sent to the prompting module, and the prompting module prompts according to the high-level signal or the low-level signal. Of course, the first module 510, the second module 520 and the processing module 530 may also be implemented by software programs and stored in a device or a storage medium, which will be described in the following embodiments.
The inventors of the present application have discovered that a user chewing with a left chewing muscle having a greater amplitude of action than the right chewing muscle results in a left reflected wave having a greater spectral width than the right reflected wave. When the user chews with the right masticatory muscle, the action amplitude of the right masticatory muscle is larger than that of the left masticatory muscle, so that the frequency spectrum width value of the right reflected wave is larger than that of the left reflected wave. Similarly, a user chews with the left and right masticatory muscles with an amplitude of motion of the left masticatory muscle equal to or nearly equal to an amplitude of motion of the right masticatory muscle, resulting in a spectral width of the reflection on the left equal to or nearly equal to a spectral width of the reflection on the right. Therefore, it can be determined as left-handed chewing or right-handed chewing or as bilateral chewing, based on the magnitude relationship between the spectral width of the left-sided reflected wave and the spectral width of the right-sided reflected wave.
The processing module 530 determines that the left side chews according to the fact that the frequency spectrum width value of the left side reflected wave is larger than that of the right side reflected wave; or, the right chewing is determined according to the fact that the frequency spectrum width value of the right reflected wave is larger than that of the left reflected wave. Alternatively, it is judged as double-sided chewing or non-single-sided chewing according to the fact that the spectral width value of the left-side reflected wave is equal to or almost equal to the spectral width value of the right-side reflected wave. For example, the spectral curve of the left reflected wave and the spectral curve of the right reflected wave shown in fig. 2 are combined, where the curve 21 is the spectral curve of the left chewing face reflected wave of the user, and the curve 22 is the spectral curve of the right chewing face reflected wave of the user. The spectral width value of curve 21 is greater than the spectral width value of curve 22, the graph indicates that the user is chewing with the left side.
In the present embodiment, the spectral width value of the left-side reflected wave and the spectral width value of the right-side reflected wave reflect the left-side mastication condition and the right-side mastication condition, respectively, and therefore, it is possible to determine whether or not one-side mastication is performed based on the spectral width value of the left-side reflected wave and the spectral width value of the right-side reflected wave.
In one possible implementation, the processing module 530 obtains the chewing time lengths of the one-sided chewing in a plurality of time periods, obtains the cumulative time length of the left-sided chewing and the cumulative time length of the right-sided chewing, obtains a difference between the cumulative time length of the left-sided chewing and the cumulative time length of the right-sided chewing, and determines whether the one-sided chewing is performed in the plurality of time periods at least according to an absolute value of the difference and a time length difference threshold. The duration difference threshold may be set according to circumstances. For example, for n (n is a natural number) chewing time periods, the 1 st, 2 nd and 3 rd segments … … nth segments, respectively obtain the chewing time length of each chewing time period, accumulate n chewing time lengths to obtain an accumulated time length, and respectively record the accumulated time length of left-side chewing and the accumulated time length of right-side chewing. The way of recording the length of time is for example to calculate the length of time chewed from the start chewing time and the end chewing time. Of course, the person skilled in the art may also calculate the chewing time in other ways, which are only illustrated here by way of example and should not be construed as limiting the scope of protection of the present application.
And the absolute value of the difference between the accumulated time length of the left chewing and the accumulated time length of the right chewing is greater than or equal to the time length difference threshold value, and the single-side chewing is judged. For the one-sided chewing situation, when the cumulative duration of the left-sided chewing is longer than the cumulative duration of the right-sided chewing, the left-sided chewing is judged; and when the cumulative duration of the left-side chewing is less than the cumulative duration of the right-side chewing, judging the right-side chewing. And if the absolute value of the difference between the cumulative duration of the left chewing and the cumulative duration of the right chewing is less than the duration difference threshold, judging the double-sided chewing.
In the present embodiment, if the absolute value of the difference between the cumulative time period of the left-side chewing and the cumulative time period of the right-side chewing is greater than or equal to the time period difference threshold, it indicates that the user chews with one side for a longer time. Thus, it is possible to automatically monitor whether unilateral chewing is performed.
Fig. 6 is a schematic diagram illustrating a connection structure of a monitoring device 600 according to another embodiment of the present invention, and compared with the embodiment shown in fig. 5, the monitoring device 600 according to this embodiment may further include: and a prompting module 640, configured to perform one-sided chewing prompting according to the result determined by the processing module 530 as one-sided chewing.
For example, the absolute value of the difference between the cumulative duration of the left-side chewing and the cumulative duration of the right-side chewing is greater than the duration difference threshold, and the cumulative duration of the left-side chewing is greater than the cumulative duration of the right-side chewing, which indicates that most of the time is left-side chewing, the prompt module 640 may prompt the user to chew on the left side for a long time, or prompt the user to chew on the right side, or prompt the user to refer to the cumulative duration of the left-side chewing and the cumulative duration of the right-side chewing for the user to adjust the. Similarly, a one-sided chew prompt may be made for situations where the user is using a right-sided chew.
In one possible implementation, the prompting module 640 is one, that is, the processing module 530 sends a trigger signal for one-sided chewing to the prompting module 640, and the prompting module 640 prompts according to the trigger signal.
In another possible implementation, the prompting module 640 includes a left prompting module and a right prompting module, and the prompting is performed according to the corresponding trigger signals sent by the processing module 530 respectively.
The prompt module 640 may be disposed on a wearable device or a mobile terminal, where the wearable device may be, for example, smart glasses, an earphone, or the like. The prompting module 640 can be an indicator light, an alarm, or a spectacle lens of smart glasses, etc.
One possible implementation mode is that an indicator light or an alarm is respectively arranged on the left side and the right side of the intelligent glasses, the left side is used for chewing for a long time by a user, the indicator light on the left side is used for flickering reminding, or the alarm is used for giving an alarm. The prompting module 640 can be arranged on the left side glasses frame and the right side glasses frame of the smart glasses; or on the left and right side arms.
One possible implementation is that by displaying the caption content on the smart glasses, i.e. with the display screen of the glasses of the smart glasses as the prompting module 640, the processing module 530 sends a prompting message of the one-sided chewing result to the glasses, e.g. the left-sided chewing has been used for a long time, and the prompting message is displayed on the glasses. The user can see the cueing information and make chewing side adjustments accordingly.
One possible implementation mode is that an indicator light or an alarm is respectively arranged on the left side or the right side of the earphone, and for the user to chew on the left side for a long time, the indicator light on the left side is used for flashing reminding, or the alarm is used for giving an alarm. The left side is for example the left earpiece of the headset and the right side is for example the right earpiece of the headset.
In one possible implementation, the prompt module 640 is disposed in the mobile terminal. When the processing module 530 determines that the user chews one-sided, the processing module sends a trigger signal for one-sided chewing to the mobile terminal, and the mobile terminal performs one-sided chewing prompting according to the trigger signal by at least one of sound prompting, indicator lamp flashing, alarm sound, caption content display and the like.
In this embodiment, a single-sided chewing prompt is given according to the result of determining that the user chews one-sided, and the user can be recommended to chew one-sided with a short chewing time, thereby reminding the user to chew uniformly.
The invention also provides a unilateral mastication monitoring method, and fig. 7 is a schematic flow chart of the monitoring method according to an embodiment of the invention, wherein the monitoring method comprises the following steps:
s710, acquiring at least one left reflected wave reflected by left masticatory muscles in a time period, and acquiring a left frequency spectrum width value according to the left reflected wave;
s720, acquiring at least one right side reflected wave reflected by the chewing muscles on the right side in the time period, and acquiring a right side frequency spectrum width value according to the right side reflected wave;
and S730, judging whether the chewing is performed on one side in the time period according to the left side spectrum width value and the right side spectrum width value.
The inventors of the present application have discovered that a user chewing with a left chewing muscle having a greater amplitude of action than the right chewing muscle results in a left reflected wave having a greater spectral width than the right reflected wave. When the user chews with the right masticatory muscle, the action amplitude of the right masticatory muscle is larger than that of the left masticatory muscle, so that the frequency spectrum width value of the right reflected wave is larger than that of the left reflected wave. Similarly, the user chews with the left and right masticatory muscles, with the amplitude of the motion of the left masticatory muscle equal to or nearly equal to the amplitude of the motion of the right masticatory muscle, resulting in a right reflection with a spectral width equal to or nearly equal to the spectral width of the left reflection. Therefore, it is possible to determine whether to chew on the left or right side, or whether to chew on the non-single side or both sides, based on the magnitude relationship between the spectral width value of the left reflected wave and the spectral width value of the right reflected wave.
Specifically, the left chewing is determined according to the fact that the frequency spectrum width value of the left reflected wave is larger than that of the right reflected wave; or, the right chewing is determined according to the fact that the frequency spectrum width value of the right reflected wave is larger than that of the left reflected wave. Alternatively, it is judged as double-sided chewing or non-single-sided chewing according to the fact that the spectral width value of the left-side reflected wave is equal to or almost equal to the spectral width value of the right-side reflected wave. Of course, it should be understood by those skilled in the art that the determination of whether to chew on the left or the right according to the spectral width value is merely for illustration and should not be construed as limiting the scope of the present application.
In the present embodiment, the spectral width value of the left-side reflected wave and the spectral width value of the right-side reflected wave reflect the left-side mastication condition and the right-side mastication condition, respectively, and therefore, it is possible to determine whether or not one-side mastication is performed based on the spectral width value of the left-side reflected wave and the spectral width value of the right-side reflected wave.
In one possible embodiment, the method further comprises: comparing the difference between the left side spectral width value and the right side spectral width value with a spectral width threshold, when the absolute value of the difference between the left side spectral width value and the right side spectral width value is greater than or equal to the spectral width threshold, judging that the user chews on one side, and judging that the user chews on the side with the larger spectral width value; otherwise, it may be determined to be a non-unilateral chew. The spectrum width threshold may be set according to circumstances.
In the present embodiment, it can be determined whether the chewing is unilateral chewing, for example, left-side chewing or right-side chewing, according to the left-side spectral width value and the right-side spectral width value. Thus, it is possible to automatically monitor whether unilateral chewing is performed.
Fig. 8 is a schematic flow chart of a monitoring method according to another embodiment of the present application, and as shown in fig. 8, the monitoring method according to the present embodiment includes the following steps:
s710, acquiring at least one left reflected wave reflected by left masticatory muscles in a time period, and acquiring a left frequency spectrum width value according to the left reflected wave;
s720, acquiring at least one right side reflected wave reflected by the chewing muscles on the right side in the time period, and acquiring a right side frequency spectrum width value according to the right side reflected wave;
s730, judging whether the chewing is performed on one side in the time period or not according to the left side spectrum width value and the right side spectrum width value at least;
s740, obtaining the chewing time length of one-side chewing in a plurality of time periods, and obtaining the cumulative time length of left-side chewing and the cumulative time length of right-side chewing;
and S750, acquiring a difference value between the left chewing accumulated time length and the right chewing accumulated time length, and judging whether the multiple time periods are single-side chewing or not according to at least an absolute value of the difference value and a time length difference threshold value.
In step S750, the time length difference threshold may be set according to the situation. For example, for n (n is a natural number) chewing time periods, the 1 st segment, the 2 nd segment and the 3 rd segment … … nth segment, respectively obtaining the chewing time length of each chewing time period, and accumulating the n chewing time lengths to obtain an accumulated time length; and acquiring the accumulated time length of left chewing and the accumulated time length of right chewing, and judging whether the multiple time periods are single-side chewing according to the absolute value of the difference value between the accumulated time length of left chewing and the accumulated time length of right chewing and a time length difference threshold value. The way of recording the length of time is for example to calculate the length of time chewed from the start chewing time and the end chewing time. Of course, the person skilled in the art may also calculate the chewing time in other ways, which are only illustrated here by way of example and should not be construed as limiting the scope of protection of the present application.
Wherein, the absolute value of the difference between the cumulative duration of the left chewing and the cumulative duration of the right chewing is greater than or equal to the duration difference threshold, and the single-sided chewing is judged; for the one-sided chewing situation, when the cumulative duration of the left-sided chewing is longer than the cumulative duration of the right-sided chewing, the left-sided chewing is judged; and when the cumulative duration of the left-side chewing is less than the cumulative duration of the right-side chewing, judging the right-side chewing. And if the absolute value of the difference between the cumulative duration of the left chewing and the cumulative duration of the right chewing is less than the duration difference threshold, judging the double-sided chewing.
In this embodiment, if the absolute value of the difference between the cumulative time length of the left-side chewing and the cumulative time length of the right-side chewing is greater than the time length difference threshold, it indicates that the user has chewed with one-side for a longer time. Thus, it is possible to automatically monitor whether unilateral chewing is performed.
In this embodiment, the method may further include: and performing unilateral mastication presentation according to the result of unilateral mastication judgment. For example, if the absolute value of the difference between the cumulative duration of the left-side chewing and the cumulative duration of the right-side chewing is greater than the duration difference threshold, and the cumulative duration of the left-side chewing is greater than the cumulative duration of the right-side chewing, which indicates that most of the time is left-side chewing, the user may be prompted to chew on the left-side for a long time, or the user may be prompted to need to chew on the right-side, or the user may be prompted to refer to the cumulative duration of the left-side chewing and the cumulative duration of the right. Similarly, a one-sided chew prompt may be made for situations where the user is using a right-sided chew.
In this embodiment, a single-sided chewing prompt is given according to the result of determining that the user chews one-sided, and the user can be recommended to chew one-sided with a small accumulated time length, thereby reminding the user to chew uniformly.
