[0003] In the related art, the user usually needs to continuously trigger the touch screen for a period of time so that the electronic device can detect the continuous triggering operation, and then analyze the information obtained from the detection to determine the heart rate detection result.

[0004] When detecting heart rate in this way, the user's continuous triggering operation needs to comply with the heart rate detection specifications in order to obtain more accurate detection results. For example, the user's triggering force should be appropriate, the triggering force should be kept stable, and the triggering position should not change frequently. However, in actual operation, it is usually difficult for users to maintain the triggering operation specifications, and when the triggering operation is not standardized, they are often unaware and unable to adjust in time, resulting in inaccurate heart rate detection results. Summary of the invention

[0028] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings.

These terms are only used to distinguish the same type of information from each other.

Depending on the context, the word "if" as used herein may be interpreted as "when the heart rate detection prompts" or "when the heart rate detection prompts" or "in response to determination".

[0031] As the quality of life continues to improve, users pay more and more attention to their health. Therefore, some manufacturers have embedded the heart rate detection function in the touch screen of electronic devices so that users can detect their heart rate without using a heart rate detection device.

[0032] In the related art, the user usually needs to continuously trigger the touch screen for a period of time so that the electronic device can detect the continuous triggering operation, and then analyze the information obtained from the detection to determine the heart rate detection result.

[0033] When detecting heart rate in this way, the user's continuous triggering operation needs to comply with the heart rate detection specifications in order to obtain more accurate detection results. For example, the user's triggering force should be appropriate, the triggering force should be kept stable, and the triggering position should not change frequently. However, in actual operation, it is usually difficult for users to maintain the triggering operation specifications, and when the triggering operation is not standardized, they are often unaware and unable to adjust in time, resulting in inaccurate heart rate detection results.

[0034] To this end, the present disclosure proposes a heart rate detection prompt method to avoid the problem in the related art that the detection results obtained by performing heart rate detection through a touch screen are inaccurate due to the user's continuous non-standard triggering operation.

[0035] Figure 1 A heart rate detection prompt method is shown as an exemplary embodiment of the present disclosure. The method is applied to an electronic device, and the touch screen of the electronic device is used for heart rate detection. Figure 1 As shown, the method may include the following steps:

[0036] Step 102, obtaining a continuous signal generated by a user continuously triggering on the touch screen, and determining fluctuations in parameter values ​​of the continuous signal.

[0037] The execution subject of the technical solution of the present disclosure can be any type of electronic device, for example, the electronic device can be a mobile terminal such as a smart phone, a tablet computer, or a fixed terminal such as a smart TV, a PC (personal computer). It should be understood that any electronic device that can be used for heart rate detection as long as the touch screen is installed can be used as the electronic device in the present disclosure. The specific type of electronic device used as the execution subject of the technical solution of the present disclosure can be determined by those skilled in the art according to actual needs, and the present disclosure does not limit this.

[0038] From the above content, it can be seen that when the user detects the heart rate through the touch screen, it is necessary to continuously trigger on the touch screen so that the electronic device can determine the user's heart rate detection result based on the detected signal. However, in the related art, the heart rate detection result is often inaccurate due to the user's triggering operation not meeting the specification.

[0039] In view of this, after obtaining the continuous signal generated by the user through continuous triggering on the touch screen, the present disclosure further determines the parameter value fluctuation of the continuous signal, and when the parameter value fluctuation does not meet the predefined parameter fluctuation standard, displays a prompt message that the trigger operation does not meet the heart rate detection specification. In other words, the present disclosure presets the parameter fluctuation standard according to the trigger operation that meets the heart rate detection specification, and based on the parameter fluctuation standard, judges the parameter value fluctuation of the detected continuous signal to determine whether the current trigger operation meets the heart rate detection specification.

[0040] It should be understood that, since the present disclosure will display corresponding prompt information when the user's trigger operation does not meet the heart rate detection specification, the user can realize that his or her trigger operation does not meet the specification according to the prompt information, and then adjust his or her trigger operation in time, thereby improving the accuracy of heart rate detection.

[0041] Step 104 , when it is determined that the fluctuation of the parameter value of the continuous signal does not meet the predefined parameter fluctuation standard, a prompt message is displayed indicating that the current trigger operation does not meet the heart rate detection specification.

[0042] In the present disclosure, hardware for heart rate detection can be separately configured in the touch screen so that the touch screen can be used for heart rate detection; or the heart rate detection function can be implemented using the hardware originally existing in the touch screen. For example, since heart rate detection and fingerprint recognition are essentially implemented through light intensity detection, heart rate detection can be implemented through the fingerprint recognition area in the touch screen. In this case, the user can continuously trigger in the fingerprint recognition area in the touch screen so that the electronic device obtains the above-mentioned continuous signal from the fingerprint recognition area, and then obtains the user's heart rate detection result based on the continuous signal.

[0043] When the heart rate detection is realized through the fingerprint recognition area, it is equivalent to multiplexing the optical fingerprint sensor contained in the electronic device as a heart rate detection sensor. For the sake of ease of understanding, the heart rate detection principle in this case is briefly described:

[0044] For the human body, changes in heart rate will cause changes in blood flow, and changes in blood flow will cause changes in the light absorption rate of the blood. It can be seen that the heart rate of the subject can be inferred by simply detecting the change in the light absorption rate of the blood. In view of this, when the optical fingerprint sensor is reused as a heart rate detection sensor, the display layer of the touch screen (for example, it can be a display unit of an OLED screen) can be used as the light transmitting end, and the optical fingerprint sensor arranged in the fingerprint recognition area can be used as the light receiving end to detect the change in light intensity before and after the light is reflected by the user's finger that continuously triggers the touch screen. On this basis, the change value of the light intensity can be analyzed according to a professional algorithm to obtain a PPG (photoelectric volume pulse wave signal) signal, and then the psychological detection results can be obtained based on the PPG signal analysis.

[0045] It should be noted that red light or green light is usually used in the process of heart rate detection. The reason is that red light and green light are less affected by the surface of the skin, but more affected by the red blood cells in the blood, and can more realistically reflect the actual situation of blood flow, thereby improving the accuracy of heart rate detection.

[0046] In actual operation, the user's continuous triggering operation should meet the heart rate detection rules in multiple dimensions in order to accurately detect the user's heart rate. For example, the force should be appropriate and the center of gravity should remain stable. Therefore, multiple parameter fluctuation standards can be preset in the electronic device. Then, after obtaining the continuous signal generated by the user through continuous triggering, the fluctuations of multiple parameter values ​​of the continuous signal can be determined, and the fluctuations of these multiple parameter values ​​can be compared with the corresponding parameter fluctuation standards. Among them, when the fluctuation of any parameter value of the continuous signal does not meet the corresponding parameter fluctuation standard, it is determined that the fluctuation of the parameter value of the continuous signal does not meet the predefined parameter fluctuation standard, and a prompt message that the current triggering operation does not meet the heart rate detection specification is displayed.

[0047] Furthermore, the present disclosure may also preset multiple prompt information to be displayed corresponding to the above-mentioned multiple parameter fluctuation standards, so that when it is determined that any parameter value of the continuous signal does not meet the corresponding parameter fluctuation standard, the prompt information to be displayed corresponding to the parameter fluctuation standard can be determined from the preset multiple prompt information to be displayed, and then the prompt information to be displayed can be displayed as the prompt information that the current trigger operation does not meet the heart rate detection specifications.

[0048] It should be understood that the user's trigger operation may not meet the heart rate detection specifications in any dimension. Therefore, by presetting multiple prompt information to be displayed corresponding to multiple parameter fluctuation standards in the electronic device, the electronic device can further display the prompt information to be displayed corresponding to the parameter value when determining "specifically which parameter value of the continuous signal does not meet the preset parameter fluctuation standard", which is equivalent to prompting the user's current trigger operation in which dimension does not meet the heart rate detection specifications. For example, the above-mentioned multiple parameter fluctuation standards can correspond to the prompt information of "unsuitable pressure", the prompt information of "unstable center of gravity", etc. Obviously, through this method, the user can be prompted to adjust the trigger operation in a more targeted manner, thereby improving the efficiency of the user's adjustment of the trigger operation.

[0049] In the present disclosure, whether the user's triggering operation complies with the heart rate detection specification can be determined based on different continuous signals.

[0050] In one embodiment, the continuous signal may be a continuous light intensity signal generated by a user continuously triggering on a touch screen. If the light intensity fluctuation of the acquired continuous light intensity signal does not meet the predefined light intensity fluctuation standard, it is determined that the parameter value fluctuation of the continuous signal does not meet the predefined parameter fluctuation standard.

[0051] It should be understood that, during the heart rate detection process, the continuous signal used for heart rate detection is also a continuous light intensity signal. In other words, the continuous light intensity signal in this embodiment is used for both heart rate detection and for determining whether the user's triggering operation complies with the heart rate detection specification. In actual operation, after obtaining the continuous light intensity signal, a corresponding light intensity signal waveform diagram can be generated to determine whether the light intensity fluctuation of the continuous light intensity signal complies with the light intensity fluctuation standard based on the light intensity signal waveform diagram. Of course, this example is only indicative, and how to determine whether the user's triggering operation complies with the heart rate detection specification based on the continuous light intensity signal can be determined by those skilled in the art according to actual needs, and the present disclosure does not limit this.

[0052] In this embodiment, whether the user's trigger operation meets the heart rate detection specification can be determined based on different fluctuation parameters of the continuous light intensity signal. For example, the fluctuation parameter can be "the intensity variation amplitude of the continuous light intensity signal" or "the intensity variation period of the continuous light intensity signal".

[0053] Among them, when determining whether the user's triggering operation complies with the heart rate detection specification through the "intensity change amplitude of the continuous light intensity signal", the "preset amplitude range" can be used as a standard for judgment. When the intensity change amplitude of the continuous light intensity signal exceeds the amplitude range, it is determined that the user's triggering force is abnormal, and then a prompt message is displayed to prompt the user that the current triggering force is abnormal. It should be understood that the user's triggering force will affect the blood flow, and then affect the intensity change amplitude of the continuous light intensity signal. Therefore, when the intensity change amplitude exceeds the amplitude range, it can be determined that the user's triggering force is abnormal.

[0054] For example, the amplitude range may be "the amplitude is not less than a predefined amplitude threshold". Then, when it is determined that the amplitude of the intensity change of the continuous light intensity signal is less than the amplitude threshold, a prompt message indicating that the user's trigger operation force is too large can be displayed. It should be understood that if the user's trigger force is too large, it will cause blood circulation to slow down, which will obviously reduce the light intensity change, that is, the light intensity change amplitude will be smaller. It can be seen that when the light intensity change amplitude is less than the normal amplitude, it can be determined that the user's trigger force is too large.

[0055] In the case of determining whether the user's triggering operation complies with the heart rate detection specification through the "intensity change amplitude of the continuous light intensity signal", the "preset amplitude fluctuation range" can also be used as a standard for judgment. At this time, multiple intensity change amplitudes of the continuous light intensity signal can be obtained, and the fluctuation value between the multiple intensity change amplitudes can be further determined. When the fluctuation value exceeds the predefined amplitude fluctuation range, it can be determined that the strength of the user's current triggering operation is unstable, and then the prompt information of the unstable strength of the current triggering operation is displayed. It should be understood that if the user's triggering strength is stable, the blood circulation speed is also stable, and accordingly, the intensity change of the detected continuous light intensity signal is also stable, which is reflected in the fact that the multiple intensity change amplitudes are not much different, that is, the fluctuation between the multiple intensity change amplitudes is small. Therefore, when it is determined that the fluctuation value between the multiple intensity change amplitudes exceeds the predefined amplitude fluctuation range, it can be determined that the user's triggering strength is unstable.

[0056] When determining whether the user's trigger operation meets the heart rate detection specifications through the "intensity change period of the continuous light intensity signal", the preset period fluctuation range can be used as a standard for judgment. After the electronic device obtains the continuous light intensity signal, it can further determine the multiple intensity change periods of the continuous light intensity signal, and determine whether the fluctuation value between these multiple intensity change periods exceeds the preset period fluctuation range. If so, it is determined that the center of gravity position of the user's current trigger operation is unstable, and then the corresponding prompt information is displayed.

[0057] It should be understood that when the user triggers the touch screen, if the center of gravity remains stable, the propagation path of the light signal is usually unchanged, and the propagation distance is also unchanged, which makes the change period of the detected continuous light intensity signal also remain stable. On the contrary, if the center of gravity is not stable, the optical path of the light signal will change, the distance of light propagation will also change accordingly, and the change period of the continuous light intensity signal will also fluctuate. It can be seen that comparing the fluctuation values ​​of multiple intensity change periods with the preset period fluctuation range can effectively determine whether the user has an unstable center of gravity during the triggering process. If so, the corresponding prompt information can be displayed to remind the user to keep the triggering posture stable.

[0058] In another embodiment, the continuous signal used to determine whether the user's current trigger operation meets the heart rate detection specification may be a "continuous touch signal" generated by the user continuously triggering on the touch screen. Wherein, when the fluctuation of the parameter value of the acquired continuous touch signal does not meet the predefined touch parameter fluctuation standard, it is determined that the fluctuation of the parameter value of the continuous signal does not meet the predefined parameter fluctuation standard.

[0059] In one case, after a continuous touch signal is acquired, the continuous touch signal can be analyzed, and if the continuous touch signal indicates that the user has continuously moved in the process of triggering the touch screen, it is determined that the center of gravity of the user's current triggering operation is unstable, and then corresponding prompt information is displayed to remind the user to keep the center of gravity stable in the process of triggering the touch screen. In actual applications, the trigger position of the user on the touch screen can be detected to determine whether the user has continuously moved in the process of continuously triggering the touch screen.

[0060] In another case, after obtaining the continuous touch signal, the continuous touch signal can also be analyzed. However, the purpose is no longer to detect the change of the trigger position, but to detect the change of the contact area. In particular, when the continuous touch signal indicates that the contact area of ​​the user continues to change during the process of triggering the touch screen, it is determined that the force of the user's current trigger operation is unstable, and a corresponding prompt message is displayed to instruct the user to keep the trigger force stable.

[0061] It should be understood that when the user triggers the touch screen, the trigger force and the contact area are usually positively correlated. The greater the trigger force, the larger the contact area between the user and the touch screen. Obviously, it is possible to judge whether the user's trigger force changes continuously based on the size of the contact area.

[0062] In another embodiment, the continuous signal used to determine whether the user's current trigger operation meets the heart rate detection specification can be a "continuous pressure signal" generated by the user continuously triggering on the touch screen. Wherein, when the pressure fluctuation of the acquired continuous pressure signal does not meet the predefined pressure fluctuation standard, it is determined that the parameter value fluctuation of the continuous signal does not meet the predefined parameter fluctuation standard.

[0063] In one case, after obtaining a continuous pressure signal, if the strength of the continuous pressure signal is not within a preset strength range, it can be determined that the strength of the user's current trigger operation is abnormal, and corresponding prompt information can be displayed. For example, the strength range can be less than a strength threshold, then, if the strength of the continuous pressure signal is greater than the strength threshold, it is determined that the strength of the user's current trigger operation is too large, and then a prompt information that the strength of the current trigger operation is too large is displayed.

[0064] In another case, after obtaining a continuous pressure signal, it can be further determined whether the strength of the continuous pressure signal changes continuously. If so, it is determined that the strength of the user's current trigger operation is unstable, and then corresponding prompt information is displayed to remind the user to keep the trigger force stable.

[0065] In this embodiment, a pressure sensor may be added to the touch screen to detect the above-mentioned continuous pressure signal.

[0066] It can be seen from the above technical solution that the electronic device of the present disclosure is preset with a parameter fluctuation standard, so that when the user performs heart rate detection through the touch screen in the electronic device, the parameter fluctuation standard can be used as a judgment basis to determine whether the user's operation of continuously triggering the touch screen during the heart rate detection process meets the heart rate detection specifications. Specifically, in the case of obtaining a continuous signal generated by the user through continuous triggering on the touch screen, the parameter fluctuation of the continuous signal can be further determined, and the parameter fluctuation can be compared with the predefined parameter fluctuation standard. If the parameter fluctuation does not meet the predefined parameter fluctuation standard, it is determined that the user's current trigger operation does not meet the heart rate detection specification. On this basis, the user can be reminded to adjust the trigger operation by displaying a prompt message so that the adjusted trigger operation meets the heart rate detection specification, thereby improving the accuracy of heart rate detection.

[0067] Furthermore, the present disclosure may preset multiple parameter fluctuation standards, and multiple prompt information to be displayed corresponding to the multiple parameter fluctuation standards. On this basis, when the electronic device determines that any fluctuation parameter value of the continuous signal does not meet the corresponding parameter fluctuation standard, it can display the prompt information to be displayed corresponding to the parameter fluctuation standard as prompt information for prompting that "the current trigger operation does not meet the heart rate detection specification." For example, in the case where the continuous signal is a continuous light intensity signal, if the intensity change amplitude of the continuous light intensity signal is less than the preset amplitude threshold, a prompt information that the trigger force of the current trigger operation is too large can be displayed. Obviously, through this method, the user's current trigger operation can be prompted in a more targeted manner to instruct the user to make corresponding adjustments.

[0068] Furthermore, the continuous signal used in the present disclosure to determine whether the user's current trigger operation meets the heart rate detection specification can be a continuous light intensity signal, a continuous touch signal, or a continuous pressure signal. This allows the present disclosure to determine which continuous signal is used to determine whether the user's current trigger operation meets the heart rate detection specification based on actual needs. In other words, the present disclosure has a wide range of application.

[0069] Next, taking “reusing the fingerprint recognition area in the touch screen as a heart rate detection area and prompting the user based on a continuous light intensity signal” as an example, the technical solution of the present disclosure is introduced.

[0070] Figure 2 FIG. 1 is a flowchart of another heart rate detection prompt method according to an exemplary embodiment of the present disclosure. The method is applied to an electronic device; Figure 2 As shown, the method comprises the following steps:

[0071] Step 201, turn on the heart rate detection function.

[0072] In this embodiment, the fingerprint recognition area in the touch screen can be reused as the heart rate detection area because both are essentially achieved by detecting changes in light intensity, but the light used, the detection time, and the signal processing logic are different.

[0073] For details, please refer to Figure 3The detection diagram shown in the figure. Regardless of fingerprint recognition or heart rate detection, the light used in both detections is emitted by the screen display layer, then reflected by the finger and absorbed by the corresponding sensor. The electronic device recognizes the fingerprint or detects the heart rate by comparing the intensity change of the emitted light and the received light. The difference between the two is that fingerprint recognition does not have strict restrictions on the light used. For example, most smartphones on the market use white light for fingerprint recognition; while heart rate detection is usually performed using red light or green light. The reason is that red light and green light can easily pass through the surface of the finger, and the intensity is easily affected by blood, so that the intensity change can more accurately reflect the heartbeat change.

[0074] It should be understood that this embodiment is equivalent to replacing the fingerprint recognition sensor (corresponding to Figure 3 The optical fingerprint module in the embodiment is reused as a heart rate detection sensor. In this way, the embodiment does not need to arrange an additional heart rate detection sensor, which greatly reduces the hardware cost.

[0075] It should be noted that, in this embodiment, any off-screen heart rate detection method can be used, for example, Figure 3 The PPG (photoplethysmography) signal shown is detected.

[0076] Step 202: Detect that the fingerprint recognition area is continuously triggered by the user.

[0077] In this embodiment, since the fingerprint recognition area is multiplexed as the heart rate detection area, the user can continuously trigger the fingerprint recognition area when the heart rate detection function is turned on, so that the electronic device can obtain the continuous light intensity signal generated by the continuous triggering for heart rate detection.

[0078] It should be noted that the present embodiment can determine whether the heart rate detection function is turned on in a variety of ways. For example, a heart rate detection control for turning on the heart rate detection function can be set in the touch screen; for another example, the duration of the user triggering the fingerprint recognition area can be monitored, and when the duration exceeds a preset time threshold, the heart rate detection function is automatically turned on.

[0079] Step 203, obtaining a continuous light intensity signal generated by continuous triggering by the user.

[0080] Step 204: draw a light intensity signal waveform diagram based on the continuous light intensity signal.

[0081] In this embodiment, a corresponding light intensity signal waveform diagram may be drawn based on the acquired continuous light intensity signal, so as to determine whether the fluctuation of the continuous light intensity signal meets the predefined fluctuation parameter standard according to the waveform diagram. For example, the light intensity variation amplitude indicated above may correspond to the amplitude of the signal wave displayed in the waveform diagram; the light intensity variation period may correspond to the variation period of the signal wave displayed in the waveform diagram.

[0082] It should be pointed out that the light intensity value at any point on the above light intensity signal waveform is actually the light intensity difference between the light emitted by the touch screen display layer and the light received by the sensor. This light intensity difference reflects the change in heart rate. Therefore, the waveform can also be regarded as a waveform of the heart rate.

[0083] Step 205, comparing the light intensity signal waveform with a predefined waveform parameter standard.

[0084] In this embodiment, various parameters of the obtained light intensity signal waveform graph may be compared with various preset waveform graph parameter standards.

[0085] For example, it is assumed that the preset waveform parameter standards can be shown in Table 1 below:

[0086] Waveform parameters Waveform parameter standard Amplitude Greater than X Amplitude Fluctuation Value Less than Y Change cycle fluctuation value Less than Z

[0087] Table 1

[0088] On this basis, the drawn waveform graph can be compared with a plurality of preset waveform graph parameter standards to determine whether the light intensity fluctuation of the light intensity continuous signal meets the predefined light intensity parameter standards. Of course, in practical applications, a standard light intensity signal waveform graph can be drawn according to a plurality of preset waveform graph parameter standards, and the drawn light intensity signal waveform graph can be compared with the standard light intensity signal waveform graph to determine whether the light intensity fluctuation of the light intensity continuous signal meets the predefined light intensity parameter standards according to the similarity obtained by comparison.

[0089] Step 206 , determining whether all parameters of the light intensity signal waveform graph meet the preset multiple waveform graph parameter standards; if not, jump to step 207 , otherwise, jump to step 209 .

[0090] In this embodiment, if all parameters of the drawn light intensity signal waveform graph meet the preset multiple waveform graph parameter standards, it proves that the user's current continuous triggering operation meets the heart rate detection specifications and no adjustment is required; otherwise, it proves that the user's current triggering operation does not meet the heart rate detection specifications, and it is necessary to further determine in which specific dimension the user does not meet the heart rate detection specifications.

[0091] Step 207, determining that the light intensity signal waveform does not meet the waveform parameter standard.

[0092] In this step, it is necessary to determine at least one waveform parameter standard that the drawn light intensity waveform does not meet from among the preset multiple waveform parameter standards, and then give a targeted reminder based on the at least one waveform parameter standard.

[0093] Specifically, the electronic device also presets prompt information corresponding to various waveform parameter standards, and the corresponding relationship can be shown in Table 2:

[0094] Waveform parameters Waveform parameter standard Tips Amplitude Greater than X The force of continuous triggering is too strong Amplitude Fluctuation Value Less than Y Continuous trigger force is unstable Change cycle fluctuation value Less than Z Continuously triggers center of gravity instability

[0095] Table 2

[0096] On this basis, when the drawn light intensity signal waveform does not meet any waveform parameter standard, the corresponding prompt information can be displayed.

[0097] For example, suppose the waveform is plotted as Figure 4 As shown, the vertical axis represents the light intensity I, and the horizontal axis represents the time T. The amplitude of the signal wave displayed is obviously smaller than the amplitude X, that is, it does not meet the amplitude standard of the waveform graph. Therefore, the prompt message "continuous trigger force is too large" can be displayed; assuming that the waveform graph drawn is as follows Figure 5 As shown in the figure, the fluctuations between the multiple amplitudes of the signal wave displayed are obviously greater than the amplitude fluctuation value Y, that is, it does not meet the amplitude fluctuation standard of the waveform graph. Therefore, the prompt message "Continuous triggering force is unstable" can be displayed; suppose the waveform graph drawn is as follows Figure 6 As shown, the fluctuation values ​​between multiple change periods of the displayed signal wave are obviously greater than the fluctuation value Z, that is, it does not meet the periodic fluctuation standard of the waveform graph. Therefore, the prompt message of "continuously triggering unstable center of gravity" can be displayed.

[0098] It should be noted that the above prompt information is only for illustration. The specific prompt information can be determined by those skilled in the art according to actual needs, and the present disclosure does not limit this. For example, based on the above “continuous trigger force is too large”, a further prompt “please reduce the trigger force” can be given. In addition, Figures 4 to 6 The waveform diagram is also schematic. It should be understood that Figures 4 to 6 It is only used to introduce the various situations where the light intensity signal waveform does not meet the waveform parameter standards. The actual waveform is not as shown. Figures 4 to 6 So smooth.

[0099] Step 208, displaying preset prompt information corresponding to the determined waveform parameter standard.

[0100] Step 209: No prompt is given.

[0101] It can be seen from the above technical solutions that through the technical solution of the present disclosure, the fingerprint recognition area in the touch screen can be reused as the heart rate detection area, and the heart rate detection can be completed using the sensor originally existing in the touch screen, which can greatly reduce the hardware cost.

[0102] In addition, the present disclosure can draw the acquired continuous light intensity signal into a light intensity signal waveform graph to more intuitively and accurately determine whether the continuous light intensity signal meets the predefined light intensity fluctuation standard. Furthermore, when the present disclosure determines that the drawn waveform graph does not meet any waveform graph parameter standard, it will display prompt information corresponding to any waveform graph parameter standard, so that the present disclosure can prompt the user more specifically to instruct the user to make corresponding adjustments to the trigger operation.
