[0033] The embodiments of the present application provide an exhalation guidance method, device, electronic device and storage medium, which can enable the user to intuitively perceive the exhalation speed and / or duration, and help standardize the user's exhalation action during forced lung function testing.

[0034] In order to make the technical personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiment of the present application will be described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, not all of the embodiments. Based on the embodiments in the present application, they should all fall within the scope of protection of the present application.

[0035] It should be noted that, in this application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplarily" or "for example" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present related concepts in a specific way.

[0036] "At least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c, where a, b, c can be single or plural.

[0037] The following first explains the special terms involved in this application:

[0038] Forced lung function test is the gold standard for diagnosing chronic obstructive pulmonary disease (COPD). Different from other physiological index detection methods such as electrocardiogram and blood oxygen, forced lung function test is an active measurement. During the test, the user needs to exhale quickly and explosively after the maximum inhalation.

[0039] See also Figure 1 , Figure 1 It is a scenario diagram of the exhalation guidance method disclosed in the embodiment of the present application. Figure 1 The illustrated scene diagram includes an electronic device 10 and a user 20, and the exhalation guidance method can be applied to the electronic device 10. The electronic device 10 has a lung function assessment function, and can support the user 20 to perform a forced lung function test.

[0040] Among them, the electronic device 10 may include general handheld screen electronic devices, such as mobile phones, smart phones, portable terminals, terminals, personal digital assistants (PDA), portable multimedia players (Personal Media Player, PMP) devices, laptop computers, notebooks (Note Pad), wireless broadband (Wireless Broadband, Wibro) terminals, tablet computers (Personal Computer, PC), smart PCs, sales terminals (Point of Sales, POS) and car computers, etc.

[0041] The electronic device 10 may also include a wearable device. A wearable device is a portable electronic device that can be worn directly on the user or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but can also realize powerful intelligent functions through software support, data interaction, and cloud server interaction, such as: computing function, positioning function, and alarm function. At the same time, they can also connect to mobile phones and various terminals. Wearable devices may include but are not limited to watches supported by wrists (such as watches, wrists, etc.), shoes supported by feet (such as shoes, socks or other products worn on the legs), glasses supported by the head (such as glasses, helmets, headbands, etc.), and various non-mainstream product forms such as smart clothing, school bags, crutches, accessories, etc.

[0042] The electronic device 10 may also include a large-scale pulmonary function meter used in a hospital, a portable pulmonary function meter, and the like.

[0043] Among them, the forced pulmonary function test is an active measurement, but in practice it is found that most users cannot correctly perform the exhalation action that meets the test standards. For example, when users undergo a forced pulmonary function test in a hospital, the doctor in charge of the test usually instructs the user on how to exhale correctly through verbal explanations and action demonstrations. However, many people still cannot correctly perform the exhalation action that meets the test standards due to limited understanding, physical fitness and other reasons. For another example, when using a portable spirometer or other portable device for a forced pulmonary function test, compared to a hospital, it is more difficult for users to perform the correct exhalation action due to the lack of guidance and supervision from professional doctors.

[0044] In the technical solution of the present application, the electronic device 10 can determine the target information according to the signal amplitude and / or duration of the sound signal generated by the user 20 during the exhalation process when detecting the user 20 exhaling, and output the target information. Since the signal amplitude of the sound signal is positively correlated with the exhalation speed of the user 20, the output of the target information can enable the user 20 to intuitively perceive the exhalation speed and / or duration, which helps to standardize the exhalation action of the user 20 during the forced pulmonary function test.

[0045] See also Figure 2 , Figure 2 FIG. 1 is a flowchart of the exhalation guidance method disclosed in the embodiment of the present application. Figure 2 The exhalation guidance method shown may include the following steps:

[0046] 201. When the electronic device detects that the user starts to exhale, it collects the sound signal generated by the user during the exhalation process.

[0047] In some embodiments, the electronic device may periodically collect sound signals generated by the user during the exhalation process through a microphone of the electronic device.

[0048] Among them, the microphone may include a microphone element and a microphone cable. The microphone element is a capacitive micro-element, which is composed of a film and a group of electrodes. When the sound wave vibrates the film, the electrode will vibrate and generate an electrical signal. The microphone cable transmits the electrical signal to the recording device of the electronic device for amplification and recording to obtain a sound signal.

[0049] In some embodiments, the electronic device detects whether the user begins to exhale, which may include:

[0050] The electronic device determines whether a designated action is received. If the designated action is received, it is determined that the user starts to exhale. If the designated action is not received, it is determined that the user does not start to exhale.

[0051] The designated action may include but is not limited to designated gestures, touching a target button, etc. The target button is a physical or virtual button used to trigger the collection of sound signals.

[0052] It has been found in practice that exhaling for a sufficiently long time is also the key to the forced lung function test. In some embodiments, the electronic device can also start a countdown to the target duration when it detects that the user begins to exhale, which can serve to prompt the user to keep exhaling for a long time.

[0053] In some embodiments, the electronic device may also start a countdown to the target duration when detecting that the user's exhalation speed exceeds a speed threshold (eg, an air flow threshold) for the first time.

[0054] The countdown may be in the form of audio or text representing time, which is not limited in the embodiments of the present application.

[0055] Currently, the forced lung function test is required to last for more than 6 seconds (s). Exemplarily, the target duration may be 6s, 7s, or 8s, etc. Exemplarily, the target duration is 6s, and the electronic device may start a 6-second countdown on the display screen of the electronic device when it detects that the user begins to exhale (for example, the user's exhalation speed exceeds the speed threshold for the first time).

[0056] In order to ensure the accuracy of the forced lung function test results, it is often required that the user and the device are relatively still, the distance between the user's mouth and the device is appropriate, and the environment is as quiet as possible.

[0057] Before step 201, the electronic device may also determine the motion state of the user relative to the electronic device; if the motion state indicates that the user is stationary relative to the electronic device, breath detection is initiated.

[0058] Furthermore, the electronic device may also output first prompt information for instructing the user to remain still relative to the electronic device when the motion state indicates that the user is in motion relative to the electronic device.

[0059] Before step 201, the electronic device may also determine the distance between the user's mouth and the electronic device; if the distance is within a specified distance interval, the exhalation detection is initiated.

[0060] Exemplarily, the specified distance interval is 10 centimeters (cm)-20 cm.

[0061] Furthermore, the electronic device may also output second prompt information for instructing the user to adjust the distance between the user's mouth and the electronic device when the distance between the user's mouth and the electronic device is not within a specified distance interval.

[0062] Before step 201, the electronic device may also determine whether the current ambient volume is lower than a volume threshold; if the current ambient volume is lower than the volume threshold, the exhalation detection is initiated.

[0063] Furthermore, the electronic device may also output third prompt information indicating that the ambient noise is too loud when the current ambient volume is greater than or equal to the volume threshold.

[0064] Before step 201, the electronic device may also guide the user to perform forceful exhalation training in advance by displaying a candle animation. The candle animation may include a candle with a lit flame, and the size of the flame may vary with the user's exhalation speed. The faster the exhalation speed, the smaller the flame.

[0065] For example, when the electronic device detects that the exhalation speed is greater than the speed threshold, the electronic device displays a candle with an extinguished flame; when the electronic device detects that the exhalation speed is less than or equal to the speed threshold, the electronic device displays a candle with a lit flame. 202. The electronic device determines the target information according to the signal amplitude and / or duration of the sound signal.

[0066] The signal amplitude is positively correlated with the user's exhalation speed. The larger the signal amplitude is, the faster the user's exhalation speed is.

[0067] The target information may be used to reflect the exhalation speed and / or duration.

[0068] In some embodiments, the target information may include visual information and / or audio information, wherein the visual information may include but is not limited to at least one of the following: animation frames, texts, and numbers.

[0069] In some embodiments, the target information may be generated periodically during the user's exhalation process; or, it may be generated at the end of exhalation, which is not limited in the embodiments of the present application.

[0070] 203. The electronic device outputs target information.

[0071] The electronic device outputting target information may include:

[0072] The electronic device outputs visual information through a display screen;

[0073] and / or,

[0074] The electronic device outputs audio information through the speaker.

[0075] By implementing this method, target information is determined based on the signal amplitude and / or duration of the sound signal generated by the user during the exhalation process, and the target information is output. Since the signal amplitude of the sound signal is positively correlated with the user's exhalation speed, the output of the target information can enable the user to intuitively perceive the exhalation speed and / or duration, which helps to standardize the user's exhalation action during the forced pulmonary function test.

[0076] See also Figure 3 , Figure 3 FIG. 1 is another flowchart of the exhalation guidance method disclosed in the embodiment of the present application. Figure 3 The target information in the exhalation guidance method shown may include animation frames. Figure 3 The exhalation guidance method shown may include the following steps:

[0077] 301. When the electronic device detects that the user starts to exhale, it collects the sound signal generated by the user during the exhalation process.

[0078] For a detailed description of step 301, see Figure 2 The description below step 201 is not repeated here.

[0079] 302. The electronic device determines an effect parameter according to a signal amplitude and / or duration of the sound signal.

[0080] Among them, the signal amplitude and duration can be positively correlated with the effect parameter. It can be understood that the longer the signal amplitude and duration, the greater the effect parameter.

[0081] In the embodiment of the present application, the effect parameter may include but is not limited to at least one of the following:

[0082] the height of the avatar's ascent;

[0083] the longitudinal distance travelled by the avatar;

[0084] The fill height of the target pattern.

[0085] 303. The electronic device determines a first animation frame according to the effect parameter.

[0086] The display effect parameters corresponding to the first animation frame may be the display effect parameters of the previous animation frame plus the effect parameters obtained in step 302. The display effect parameters of the animation frame may refer to the effect parameters finally presented by the animation frame.

[0087] 304. The electronic device outputs a first animation frame.

[0088] In some embodiments, the output of the animation frame may be continuously executed during the entire exhalation process of the user, or may be continuously executed only for a period of time immediately before the start of exhalation, which is not limited in the embodiments of the present application.

[0089] In the case where the output of the animation frame is only executed for a period of time immediately before the start of exhalation, the electronic device determines the effect parameters based on the signal amplitude and / or duration of the sound signal, which may include: within the specified time period, the electronic device determines the effect parameters based on the signal amplitude and / or duration of the sound signal.

[0090] The specified time length refers to a period of time immediately before the start of exhalation. Exemplarily, the specified time length is within the first second (s), within the first 1.5s, or within the first 2s of the sound signal collection.

[0091] It should be noted that regardless of whether the output of the first animation frame is continuously executed during the entire exhalation process of the user or only for a period of time before the start of exhalation, the process of the electronic device determining the effect parameters based on the signal amplitude and / or duration of the sound signal can be referred to the following introduction.

[0092] In some embodiments, the electronic device determines the effect parameters according to the signal amplitude of the sound signal, which may include: the electronic device determines the effect parameters according to the signal amplitude of the sound signal and an amplitude relationship table; wherein the amplitude relationship table may include the correspondence between the signal amplitude and the effect parameter.

[0093] The amplitude relationship table may include multiple amplitude intervals and effect parameters corresponding to each amplitude interval. The electronic device may search for the target amplitude interval where the signal amplitude of the sound signal is located from the multiple amplitude intervals in the amplitude relationship table, and obtain the effect parameters corresponding to the target amplitude interval.

[0094] In some embodiments, the electronic device determines the effect parameters according to the duration, which may include: the electronic device determines the effect parameters according to the duration and a duration relationship table; wherein the duration relationship table may include a correspondence between the duration and the effect parameters.

[0095] The duration relationship table may include multiple duration intervals and effect parameters corresponding to each duration interval. The electronic device may search for the target duration interval where the above-mentioned duration is located from the multiple duration intervals in the duration relationship table, and obtain the effect parameters corresponding to the target duration interval.

[0096] In some embodiments, the electronic device determines the effect parameter based on the signal amplitude and duration of the sound signal, which may include: the electronic device determines a first effect parameter component based on the signal amplitude of the sound signal; and, determines a second effect parameter component based on the duration; and, obtains the effect parameter based on the first effect parameter component and the second effect parameter component.

[0097] Among them, the determination method of the first effect parameter component and the second effect parameter component can be referred to the above description, which will not be repeated here. The effect parameter can be obtained by averaging, weighting, or summing the first effect parameter component and the second effect parameter component, which is not limited in the embodiment of the present application.

[0098] In some embodiments, during the entire exhalation process of the user, if the user stops exhaling or the exhalation speed is too slow, the animation presents a fallback effect. For details, see the following description:

[0099] In some embodiments, within a specified time period, the electronic device determines the effect parameters based on the signal amplitude and / or duration of the sound signal, which may include: within the specified time period, if the electronic device detects that the user has stopped exhaling, the initial effect parameters are used as the effect parameters; within the specified time period, if the electronic device detects that the user has not stopped exhaling, the effect parameters are determined based on the signal amplitude and / or duration of the sound signal.

[0100] When the effect parameter obtained in step 302 is not the initial effect parameter, the corresponding display effect parameter of the first animation frame may be the effect parameter obtained in step 302 accumulated on the basis of the display effect parameter of the previous animation frame.

[0101] When the effect parameters obtained in step 302 are initial effect parameters, the display effect parameters corresponding to the first animation frame are the initial effect parameters.

[0102] The initial effect parameter may be a preset parameter, and the animation frame corresponding to the initial effect parameter may be the initial animation frame of the animation. Exemplarily, when the effect parameter is the rising height of the avatar, the initial effect parameter includes the rising height being 0. Exemplarily, when the effect parameter is the longitudinal travel distance of the avatar, the initial effect parameter includes the longitudinal travel distance being 0. Exemplarily, when the effect parameter is the filling height of the target pattern, the initial effect parameter includes the filling height being 0.

[0103] It can be understood that if the user continues to exhale within a specified time period, the display effect parameters can continue to increase with the change of the signal amplitude and / or duration of the sound signal. If the user stops exhaling within the specified time period, the display effect parameters return to the initial effect parameters.

[0104] By implementing this method, if the user stops exhaling within a period of time before the start of exhalation, the displayed effect parameters return to the initial effect parameters, which can force the user to exhale quickly and explosively to the maximum extent.

[0105] For example, when the effect parameter is the rising height of the virtual image, the virtual image is a balloon, and the specified duration is within the first second:

[0106] If the user continues to exhale, the balloon height corresponding to the next animation frame is greater than the balloon height corresponding to the previous animation frame, and the animation presented is that the balloon continues to rise. This animation can be seen in Figure 4A ,like Figure 4A The animation shown includes two consecutive animation frames, namely animation frame 1 and animation frame 2, wherein the balloon height corresponding to animation frame 1 is smaller than the balloon height corresponding to animation frame 2.

[0107] If the user stops exhaling, the balloon height corresponding to the animation frame when the exhalation is interrupted is 0, and the balloon height corresponding to the animation frame before the exhalation is interrupted is greater than 0. The animation presented is that the balloon falls back to 0. This animation can be seen in Figure 4B ,like Figure 4B The animation shown includes two consecutive animation frames, namely animation frame 1 and animation frame 2, wherein the balloon height corresponding to animation frame 1 is greater than 0, and the balloon height corresponding to animation frame 2 is equal to 0.

[0108] For example, when the effect parameter is the longitudinal travel distance of the avatar, the avatar is a car, and the specified time duration is within the first second:

[0109] If the user continues to exhale, the distance traveled by the car in the next animation frame is greater than the distance traveled by the car in the previous animation frame, and the animation presented is that the car keeps moving forward. Figure 5A ,like Figure 5A The animation shown includes two consecutive animation frames, namely animation frame 1 and animation frame 2, wherein the driving distance of the car in animation frame 1 is shorter than the driving distance of the car in animation frame 2.

[0110] If the user stops exhaling, the distance traveled by the car in the animation frame when exhaling is interrupted is 0, that is, when exhaling is interrupted, the car is at the starting position. The distance traveled by the car in the animation frame before exhaling is interrupted is greater than 0, and the animation presented is the car returning to the starting position. This animation can be seen in Figure 5B ,like Figure 5B The animation shown includes two consecutive animation frames, namely animation frame 1 and animation frame 2, wherein the driving distance of the car in animation frame 1 is greater than 0, and the driving distance of the car in animation frame 2 is equal to 0.

[0111] For example, when the effect parameter is the fill height of the target pattern, the target pattern is a rectangle, and the specified duration is within the first second:

[0112] If the user continues to exhale, the filling height corresponding to the next animation frame is greater than the filling height corresponding to the previous animation frame, and the animation presented is that the height of the rectangular filling continues to increase. This animation can be seen in Fig. 6A ,like Fig. 6A The animation shown includes two consecutive animation frames, namely animation frame 1 and animation frame 2, wherein the filling height of the rectangle in animation frame 1 is smaller than the filling height of the rectangle in animation frame 2.

[0113] If the user stops exhaling, the fill height of the animation frame when the exhalation is interrupted is 0, and the fill height of the animation frame before the exhalation is interrupted is greater than 0. The animation presented is that the height of the rectangular fill falls back to 0. This animation can be seen in Figure 6B ,like Figure 6B The animation shown includes two consecutive animation frames, namely animation frame 1 and animation frame 2, wherein the filling height of the rectangle in animation frame 1 is greater than 0 and less than the filling height of the rectangle in animation frame 2 which is equal to 0.

[0114] In some embodiments, when the output of animation frames is continuously executed during the entire exhalation process of the user, the electronic device can also, after the specified duration ends, switch the first animation frame at the end of the specified duration to the second animation frame corresponding to the initial effect parameters if the signal amplitude of the current sound signal is less than or equal to the first amplitude threshold; and continue to display the first animation frame at the end of the specified duration if the signal amplitude of the current sound signal is greater than the first amplitude threshold.

[0115] The first amplitude threshold may be preset by the electronic device and is used to define the speed of exhalation. If the signal amplitude of the sound signal is greater than the first amplitude threshold, it means that the exhalation speed is fast, otherwise, it means that the exhalation speed is slow. The second animation frame may refer to the initial frame of the animation.

[0116] It can be understood that after the specified time, if the exhalation speed is fast, the first animation frame corresponding to the end of the specified time is maintained, and if the exhalation speed is slow, the first animation frame corresponding to the end of the specified time is switched to the second animation frame.

[0117] For example, when the effect parameter is the rising height of the virtual image, the virtual image is a balloon, and the specified duration is within the first second:

[0118] If the user continues to exhale quickly after 1 second, the balloon's rising height remains unchanged. Fig. 7A ,like Fig. 7A The animation shown includes two consecutive animation frames, namely animation frame 1 and animation frame 2, wherein the balloon height corresponding to animation frame 1 is the same as the balloon height corresponding to animation frame 2.

[0119] If the user's exhalation speed slows down after 1 second, the balloon will fall back to 0. For the corresponding animation, see Figure 7B ,like Figure 7B The animation shown includes two consecutive animation frames, namely animation frame 1 and animation frame 2, wherein animation frame 1 is the animation frame before the exhalation speed slows down, and the corresponding balloon height is greater than 0, and animation frame 2 is the animation frame when the exhalation speed slows down, and the corresponding balloon height is 0.

[0120] For example, when the effect parameter is the longitudinal travel distance of the avatar, the avatar is a car, and the specified time duration is within the first second:

[0121] If the user continues to exhale quickly after 1 second, the car's driving distance remains unchanged. Fig. 8A ,like Fig. 8A The animation shown includes two consecutive animation frames, namely animation frame 1 and animation frame 2, wherein the driving distance corresponding to animation frame 1 is the same as the driving distance corresponding to animation frame 2.

[0122] If the user's exhalation speed slows down after 1 second, the car returns to the starting position. For the corresponding animation, see Figure 8B ,like Figure 8B The animation shown includes two consecutive animation frames, namely animation frame 1 and animation frame 2, wherein animation frame 1 is the animation frame before the exhalation speed slows down, and the corresponding driving distance is greater than 0, and animation frame 2 is the animation frame when the exhalation speed slows down, and the corresponding driving distance is 0.

[0123] For example, when the effect parameter is the fill height of the target pattern, the target pattern is a rectangle, and the specified duration is within the first second:

[0124] If the user continues to exhale quickly after 1 second, the filling height of the target pattern will remain unchanged. Fig. 9A ,like Fig. 9AThe animation shown includes two consecutive animation frames, namely animation frame 1 and animation frame 2, wherein the filling height corresponding to animation frame 1 and the filling height corresponding to animation frame 2 are the same.

[0125] If the user's exhalation speed slows down after 1 second, the filling height of the target pattern will drop back to 0. For the corresponding animation, please refer to Fig. 9B ,like Fig. 9B The animation shown includes two consecutive animation frames, namely animation frame 1 and animation frame 2, wherein animation frame 1 is the animation frame before the exhalation speed slows down, and the corresponding filling height is greater than 0, and animation frame 2 is the animation frame when the exhalation speed slows down, and the corresponding filling height is 0.

[0126] In some embodiments, during the entire exhalation process of the user, the animation effect presented by the animation frame is a continuously positively changing animation, that is, there is no drop in the display effect parameters.

[0127] Exemplarily, when the effect parameter is the rising height of the virtual image, the virtual image is a balloon, and the balloon continues to rise during the entire exhalation process of the user.

[0128] Exemplarily, when the effect parameter is the longitudinal travel distance of the virtual image, the virtual image is a car, and the car keeps moving forward during the entire exhalation process of the user.

[0129] Exemplarily, when the effect parameter is the filling height of the target pattern, the target pattern is a rectangle, and the rectangle is continuously filled during the entire exhalation process of the user.

[0130] The method for determining the effect parameters corresponding to any animation frame is described below:

[0131] In some embodiments, the electronic device determines the effect parameter according to the signal amplitude of the sound signal, which may include:

[0132] Within the specified time period, the electronic device determines the effect parameter according to the signal amplitude of the sound signal and the first amplitude relationship table;

[0133] After the specified time, the electronic device determines the effect parameter according to the signal amplitude of the sound signal and the second amplitude relationship table; wherein, for the same signal amplitude, the corresponding effect parameter in the first amplitude relationship table is greater than the corresponding effect parameter in the second amplitude relationship table.

[0134] By implementing this method, the effect parameters within the specified time length change quickly, and the effect parameters after the specified time length change slowly, thereby achieving the purpose of prompting the user to exhale as quickly as possible within the specified time length.

[0135] The electronic device determines the effect parameters according to the signal amplitude or duration of the sound signal, which may include:

[0136] Within a specified time period, the electronic device determines the effect parameter according to the signal amplitude of the sound signal;

[0137] After the specified duration, the electronic device determines the effect parameter according to the duration of the sound signal.

[0138] It is understandable that within a specified duration, the effect parameter may continuously change with changes in the signal amplitude of the sound signal, and after the specified duration, the effect parameter may continuously change with changes in the duration.

[0139] In order to ensure that the user performs an effective forced lung function test, the electronic device can also output exhalation rule information before the test begins.

[0140] In some embodiments, the electronic device may further display a touch button for triggering the start of the test before the test starts.

[0141] In some embodiments, after step 302, the electronic device may also determine the parameter coordinates corresponding to the current moment according to the effect parameters, and update the guidance curve according to the parameter coordinates.

[0142] The horizontal and vertical coordinates of the parameter coordinates corresponding to the current moment are time and cumulative effect parameters. For the explanation of the cumulative effect parameter, please refer to the above description for the explanation of the above display effect parameter, which will not be repeated here. The guide curve represents the changing relationship between time and cumulative effect parameters.

[0143] See also Fig. 10A , Fig. 10A It is a diagram of the animation effect curve disclosed in the embodiment of this application. Fig. 10A There is a moment when the cumulative effect parameter falls back in the animation effect curve shown, where the cumulative effect parameter is represented by s.

[0144] See also Fig. 10B , Fig. 10B is another illustration of the animation effect curve disclosed in the embodiment of the present application. Fig. 10B There is no moment when the cumulative effect parameter falls back in the animation effect curve shown. The cumulative effect parameter is represented by s.

[0145] By implementing this method, the electronic device can also guide the user to standardize the exhalation action through a changing curve, with a small amount of calculation, more timely guidance, and better effect of standardizing the user's exhalation action.

[0146] Since the forced pulmonary function test is required to last for more than 6 seconds (s), in some embodiments, when the user stops exhaling, if the continuous exhalation duration corresponding to the current moment is less than the duration threshold, an indication message instructing re-exhalation is output.

[0147] By implementing the above method, the exhalation speed and / or duration can be displayed to the user in an image-based and interesting way by outputting animation frames, which further helps to standardize the user's exhalation action during the forced lung function test.

[0148] See also Fig.11 , Fig.11 FIG. 1 is another flowchart of the exhalation guidance method disclosed in the embodiment of the present application. Fig.11 The exhalation guidance method shown may include the following steps:

[0149] 1101. When the electronic device detects that the user starts to exhale, the electronic device collects the sound signal generated by the user during the exhalation process.

[0150] For a detailed description of step 1101, see Figure 2 The description below step 201 is not repeated here.

[0151] 1102. The electronic device determines a target score according to a signal amplitude and / or duration of the sound signal.

[0152] Among them, step 1102 can be executed by the electronic device when it detects that the user starts to exhale, or it can be executed by the electronic device when it determines that the signal amplitude of the current sound signal is greater than the first amplitude threshold (that is, after the user starts to exhale forcefully).

[0153] 1103. The electronic device outputs the target score.

[0154] The target score is used to indicate the qualified level of exhalation. The higher the target score is, the higher the qualified level of exhalation is.

[0155] In some embodiments, the electronic device may pre-set a score update cycle, and during the user's exhalation or after the user begins to exhale forcefully, the electronic device may update the target score once in each score update cycle. Exemplarily, the score update cycle is 0.5s.

[0156] In some embodiments, the update of the target score in each score update cycle is related to the amplitude and / or duration of the sound signal. The electronic device determines the target score according to the signal amplitude and / or duration of the sound signal, which may include:

[0157] The electronic device obtains a score increment corresponding to the first score update period according to the signal amplitude and / or duration of each sound signal in the first score update period; wherein the signal amplitude and / or duration of each sound signal in the first score update period is proportional to the score increment corresponding to the first score update period;

[0158] The electronic device determines the target score corresponding to the first score update period according to the target score in the previous score update period of the first score update period and the score increment.

[0159] The first score update period is any score update period. It should be noted that when the first score update period is the first score update period, the target score in the previous score update period of the first score update period is 0.

[0160] In some embodiments, the electronic device obtains the score increment corresponding to the first score update period according to the signal amplitude and / or duration of each sound signal within the first score update period, which may include:

[0161] The electronic device determines the score increment corresponding to each sound signal according to the signal amplitude and / or duration of each sound signal within the first score update period;

[0162] The electronic device accumulates the score increment corresponding to each sound signal to obtain the score increment corresponding to the first score update period.

[0163] The electronic device may pre-set a first score table and / or a second score table, wherein the first score table includes a correspondence between signal amplitude and score, and in the first score table, the score is positively correlated with the signal amplitude. The second score table may include a correspondence between duration and score, and in the second score table, the score is positively correlated with duration. The electronic device may determine the score increment corresponding to each sound signal based on the first score table and / or the second score table.

[0164] In some embodiments, the electronic device obtains the score increment corresponding to the first score update period according to the signal amplitude and / or duration of each sound signal within the first score update period, which may include:

[0165] The electronic device obtains a parameter increment corresponding to the first score update period according to the signal amplitude and / or duration of each sound signal within the first score update period;

[0166] The electronic device determines the score increment corresponding to the first score update period according to the parameter increment.

[0167] The electronic device may pre-set a third score table, which may include multiple parameter increment intervals and scores corresponding to each parameter increment interval. The electronic device may search the third score table for a score that matches the parameter increment corresponding to the first score update period, and use the score as the score increment corresponding to the first score update period.

[0168] It should be noted that in the third scoring table, the parameter increment and the score increment are positively correlated.

[0169] In some embodiments, after the user starts to exhale or after the user starts to exhale forcefully, the parameter increment corresponding to the score update period may be related to the signal amplitude of the sound signal within the score update period.

[0170] Based on this, the electronic device obtains the parameter increment corresponding to the first score update period according to the signal amplitude of each sound signal within the first score update period, which may include but is not limited to the following methods:

[0171] Mode 1: The electronic device obtains a parameter increment corresponding to the first score update period according to the signal amplitude of each sound signal in the first score update period and the amplitude relationship table.

[0172] It is understandable that after the user starts to exhale or after the user starts to exhale forcefully, the parameter increment corresponding to each score update cycle is determined according to a unique amplitude relationship table.

[0173] The electronic device obtains the parameter increment corresponding to the first score update period according to the signal amplitude of each sound signal in the first score update period and the amplitude relationship table, which may include:

[0174] The electronic device determines the effect parameter corresponding to each sound signal in the first score update period according to the signal amplitude of each sound signal in the first score update period and the amplitude relationship table;

[0175] According to the effect parameter corresponding to each sound signal in the first score update period, a parameter increment corresponding to the first score update period is determined.

[0176] Among them, the parameter increment corresponding to the first score update period can be obtained by averaging, summing or median-calculating the effect parameter corresponding to each sound signal within the first score update period, and the embodiment of the present application is not limited thereto.

[0177] Method 2: Within a specified time period, the electronic device obtains a parameter increment corresponding to the first score update period based on the signal amplitude of each sound signal within the first score update period and the first amplitude relationship table; after the specified time period, the electronic device obtains a parameter increment corresponding to the first score update period based on the signal amplitude of each sound signal within the first score update period and the second amplitude relationship table; wherein, for the same signal amplitude, the corresponding effect parameter in the first amplitude relationship table is greater than the corresponding effect parameter in the first amplitude relationship table.

[0178] It is understandable that after the user starts to exhale or after the user starts to exhale forcefully, the parameter increment corresponding to each score update period is determined according to the first amplitude relationship table within the specified time, and after the specified time, the parameter increment corresponding to each score update period is determined according to the second amplitude relationship table. Since for the same signal amplitude, the corresponding effect parameter in the first amplitude relationship table is greater than the corresponding effect parameter in the second amplitude relationship table, it can be seen that compared with after the specified time, the target score within the specified time increases faster, which can not only prompt the user to exhale quickly and explosively.

[0179] In some embodiments, after the user starts to exhale or after the user starts to exhale forcefully, the parameter increment corresponding to the score update period may be related to the signal amplitude or duration of the sound signal within the score update period.

[0180] Based on this, the electronic device obtains the parameter increment corresponding to the first score update period according to the signal amplitude or duration of each sound signal in the first score update period, which may include:

[0181] Within the specified time period, the electronic device obtains a parameter increment corresponding to the first score update period according to the signal amplitude of each sound signal within the first score update period;

[0182] After the specified time period, the electronic device obtains the parameter increment corresponding to the first score update period according to the duration corresponding to the first score update period.

[0183] Among them, regarding the electronic device obtaining the parameter increment corresponding to the first score update period according to the signal amplitude of each sound signal within the first score update period, please refer to the above description, which will not be repeated here.

[0184] The duration corresponding to the first score update cycle may include: the duration of continuous exhalation corresponding to the end time corresponding to the first score update cycle. Exemplarily, if the first score update cycle is the first score update cycle, then the duration corresponding to the first score update cycle is the duration of continuous exhalation corresponding to the end time of the first score update cycle, that is, a complete score update cycle.

[0185] The electronic device obtains the parameter increment corresponding to the first score update period according to the duration corresponding to the first score update period, which may include: the electronic device obtains the parameter increment corresponding to the first score update period according to the duration corresponding to the first score update period and a duration relationship table.

[0186] The duration relationship table may include multiple duration intervals and effect parameters corresponding to each duration interval. The electronic device may search for a target duration interval in which the duration corresponding to the first score update period is located from the multiple duration intervals in the duration relationship table, obtain the effect parameter corresponding to the target duration interval, and use the effect parameter as the parameter increment corresponding to the first score update period.

[0187] It can be understood that during the entire exhalation process of the user, or after the user begins to exhale forcefully, the parameter increment corresponding to each score update period is determined according to the signal amplitude of the sound signal within a specified time period, and after the specified time period, the parameter increment is determined according to the duration corresponding to the score update period. Since the signal amplitude and the duration are positively correlated with the parameter increment, the larger the amplitude signal and the longer the duration, the larger the target score will be, which can not only promote the user to exhale quickly and explosively, but also promote the user to exhale for a long time.

[0188] In some embodiments, within a specified duration, the update of the target score in each score update cycle is related to the amplitude and / or duration of the sound signal. After the specified duration, the basis for updating the target score in each score update cycle can be the maximum score increment within the specified duration. In this way, the user can be encouraged not only to exhale as quickly as possible within the specified duration, but also to continue to exhale for as long as possible.

[0189] Based on this, the electronic device obtains the score increment corresponding to the first score update period according to the signal amplitude and / or duration of each sound signal in the first score update period, which may include:

[0190] Within the specified time period, according to the signal amplitude and / or duration of each sound signal within the first score update period, obtain a score increment corresponding to the first score update period;

[0191] The electronic device may also, after the specified time period, use the highest score increment within the specified time period as the score increment corresponding to the second score update period;

[0192] The target score corresponding to the second score update period is determined according to the target score in the previous score update period of the second score update period and the score increment corresponding to the second score update period.

[0193] Among them, for the description of how the electronic device obtains the score corresponding to the first score update period based on the signal amplitude and / or duration of each sound signal in the first score update period within the specified time period, please refer to the above description and will not be repeated here.

[0194] For example, if the specified time period includes score update cycle 1 and score update cycle 2, where 7 points are added in score update cycle 1 and 5 points are added in score update cycle 2, then after the specified time period, 7 points are fixedly added in each score update cycle.

[0195] In some embodiments, the electronic device may also output a score increment corresponding to each score update cycle.

[0196] In some embodiments, the target score may be output after the user finishes exhaling, and the electronic device determines the target score based on the signal amplitude and duration of the sound signal, which may include: the electronic device determines the target score based on the duration when the user finishes exhaling and the signal amplitude of each sound signal within a specified duration.

[0197] In some embodiments, the electronic device determines the target score according to the duration of the user's end of exhalation and the signal amplitude of each sound signal within the specified duration, which may include:

[0198] The electronic device determines a first score according to the duration of the user finishing exhaling;

[0199] The electronic device determines a second score according to the signal amplitude of each sound signal within the specified time period;

[0200] The electronic device accumulates the first score and the second score to obtain a target score.

[0201] Among them, the duration is positively correlated with the first score.

[0202] In some embodiments, the electronic device determines the second score according to the signal amplitude of each sound signal within the specified time period, which may include but is not limited to the following methods:

[0203] Method 1: The electronic device determines the maximum signal amplitude according to the signal amplitude of each sound signal within a specified time period, and determines the second score according to the maximum signal amplitude; wherein the signal amplitude and the second score are positively correlated.

[0204] Method 2: The electronic device obtains the number of sound signals whose corresponding signal amplitudes are greater than the second amplitude threshold within a specified time period, and determines the second score according to the number; wherein the number and the second score are positively correlated.

[0205] The second amplitude threshold is greater than the first amplitude threshold.

[0206] In some embodiments, after step 1103, the electronic device may also determine whether the target score is greater than a score threshold. If so, a target gift matching the target score is obtained from the virtual gift pool and the target gift is output.

[0207] The score threshold is preset by the electronic device and is used to measure whether the target score is a qualified score, and the exhalation corresponding to the qualified score is a qualified exhalation. It can be understood that when the target score is greater than the score threshold, the target score is a qualified score, and when the target score is less than or equal to the qualified score, the target score is an unqualified score.

[0208] By implementing this method, when the target score is greater than the score threshold, a virtual gift matching the target score can be output, which is helpful to improve the fun of the test.

[0209] In some embodiments, the electronic device may also evaluate the test result of the forced pulmonary function test based on the sound signal generated by the user during the exhalation process when the target score is greater than the score threshold.

[0210] In some embodiments, the electronic device may also output indication information indicating that the exhalation is unqualified when the target score is less than or equal to the score threshold.

[0211] By implementing this method, during the user's exhalation process, the electronic device can also update the score based on the exhalation speed and / or duration, which can play an explicit encouraging role and further help to standardize the user's exhalation action.

[0212] In some embodiments, the target information includes animation frames, target scores, and score increments.

[0213] For example, when the effect parameter is the rising height of the balloon, during the user's exhalation, the exhalation guidance interface displayed by the electronic device can refer to Figure 12A-12E .in, Fig. 12A This is the exhalation guidance interface before the test starts. Fig. 12A The exhalation guidance interface shown includes a virtual button 1201 for triggering the test; Fig. 12B This is the exhalation guidance interface at the beginning of the test, when the balloon is at the starting position 0 below the red line; Fig. 12C It is the exhalation guidance interface at 1 second. The score increment at 1 second is 10 points, and the target score is 50 points. Fig.12D It is the exhalation guidance interface at 3 seconds. The score increment at 3 seconds is 10 points, and the target score is 70 points. Fig.12E It is the exhalation guidance interface at the end of continuous exhalation (6s). At this time, the target score is 100 points, the score increment is 10 points, and the balloon falls back to 0 (that is, the starting position below the red line).

[0214] in, Figure 12B-12E The exhalation guide interface shown also displays a plurality of grids arranged from top to bottom for calibrating the height of the balloon so that the user can intuitively know the height change of the balloon within 1 second.

[0215] In some embodiments, the fill color of the grid may be darker from bottom to top.

[0216] It is understandable that the user enters the virtual Fig. 12B At this time, the user starts to exhale quickly, and the balloon continues to rise within 1s. Within 1s-6s, the user keeps exhaling quickly, and the balloon height on the exhalation guide interface within 1s-6s is the same as the balloon height on the exhalation guide interface at 1s. At 6s, the user stops exhaling, and the balloon height on the exhalation guide interface drops back to 0 at 6s.

[0217] Exemplarily, 12F is another exhalation guide interface at 3 seconds. As shown in the figure, the score increment at 3 seconds is 10 points, the target score is 70 points, and the balloon height drops back to 0.

[0218] It is understandable that within 1s-3s, the user always maintains a fast exhalation speed, and at 3s, the user stops exhaling or the exhalation speed is too slow.

[0219] See also Fig.13 , Fig.13 is a diagram of the exhalation guiding device disclosed in the embodiment of the present application.

[0254] See also Fig.14 , Fig.14 FIG. 1 is a structural diagram of an electronic device disclosed in an embodiment of the present application. Fig.14 The electronic device shown includes: a processor 1410, a memory 140, a display unit 1430, an input unit 1440, a sensor 1450, an audio circuit 1460 and other components.
