Description

Method for adjusting pressure threshold and electronic equipment
Technical Field
The embodiment of the application relates to the technical field of touch control, in particular to a method for adjusting a pressure threshold and an electronic device.
Background
With the development of touch screens, the underscreen fingerprints are gradually applied to electronic devices as a new technical breakthrough of touch screens. The fingerprint under the screen is that a fingerprint sensor is integrated under a touch screen of the electronic equipment, and the fingerprint sensor responds to touch operation of a user on a preset position in the touch screen and can collect fingerprint information of the user.
When fingerprint information of a user is collected in response to touch operation of the user on a preset position in the touch screen, certain requirements are made on the fit degree of the finger of the user and the touch screen. The closer the user finger is attached to the touch screen, the higher the quality of the fingerprint image of the fingerprint information acquired by the fingerprint sensor is, and the higher the success rate of user identity verification (namely fingerprint identification) by using the fingerprint information is. In order to improve the success rate of fingerprint verification, the electronic equipment can guide the user to increase the pressing pressure properly when inputting the fingerprint information so as to ensure that the fitting degree of the finger of the user and the touch screen meets the requirement. For example, a pressure sensor may be disposed under a touch screen of the electronic device, and the pressure sensor is used for collecting the pressing pressure of the finger of the user on the touch screen. When the pressing pressure collected by the pressure sensor is greater than the pressure threshold value of the electronic equipment, the electronic equipment adopts fingerprint information to check the identity of the user.
Disclosure of Invention
The embodiment of the application provides a method for adjusting a pressure threshold and an electronic device, which can dynamically adjust the pressure threshold of the electronic device.
In a first aspect, the present technical solution provides a method for adjusting a pressure threshold, where the method may be applied to an electronic device including a touch screen, and the electronic device may further include a fingerprint sensor and a pressure sensor. The method of adjusting the pressure threshold may comprise: the electronic equipment displays a first interface on the touch screen; the electronic equipment acquires fingerprint information input by a user on a first interface through a fingerprint sensor, and acquires pressing pressure on the touch screen when the user inputs the fingerprint information on the first interface through a pressure sensor; if the pressing pressure is larger than or equal to the pressure threshold value of the electronic equipment, the electronic equipment carries out user identity verification on the fingerprint information; if the user identity passes the verification, the electronic equipment reduces the pressure threshold of the electronic equipment; and if the user identity verification fails, the electronic equipment raises the pressure threshold of the electronic equipment.
As can be appreciated, if the user identity verification passes, the electronic device turns down the pressure threshold of the electronic device; and if the user identity verification fails, the electronic equipment raises the pressure threshold of the electronic equipment. In both cases, the electronic device may have one of the situations, for example, if the user identity check passes, the electronic device turns the pressure threshold of the electronic device down, or if the user identity check fails, the electronic device turns the pressure threshold of the electronic device up. Of course, the electronic device may also have the above two cases: if the user identity passes the verification, the electronic equipment reduces the pressure threshold of the electronic equipment; and if the user identity verification fails, the electronic device raises the pressure threshold of the electronic device.
In the embodiment of the application, if the user identity passes the verification, the electronic equipment can lower the pressure threshold of the electronic equipment; if the user identity verification fails, the electronic device may raise the pressure threshold of the electronic device. Namely, the electronic equipment can dynamically adjust the pressure threshold value, and the user experience of the user in the identification of the fingerprint under the screen is improved.
It is to be understood that the electronic device may be configured to perform the user identity verification only when the pressing pressure is greater than or equal to the pressure threshold of the electronic device. Therefore, if the user identity passes the verification, the fingerprint image quality of the fingerprint information collected by the fingerprint sensor is high, and the user identity can be guaranteed to pass the verification. The higher parameter of the fingerprint image quality of the fingerprint information acquired by the fingerprint sensor may be due to two reasons: the fingerprint lines of the user are clear and are easy to collect; the real-time pressing pressure used when the user inputs the fingerprint information is large, and the finger is tightly attached to the touch screen. For any reason, if the electronic device appropriately adjusts the pressure threshold value and the fingerprint sensor re-acquires the fingerprint information of the user, the electronic device may pass the user identity verification using the fingerprint information re-acquired by the fingerprint sensor. Therefore, in this case, the electronic device can appropriately turn down the pressure threshold of the electronic device.
If the user identity verification fails, it may be due to two reasons: the user does not use the correct finger to input fingerprint information; the fingerprint lines of the user are fuzzy and not easy to be collected, and the pressing pressure used when the user inputs the fingerprint information can not ensure that the fingerprint sensor collects the fingerprint information with higher parameters of the fingerprint image quality. If the user identity verification fails due to the second reason, the electronic device appropriately increases the pressure threshold of the electronic device, so that the possibility that the user identity verification performed by using the fingerprint information re-acquired by the fingerprint sensor passes can be improved. Thus, in this case, the electronic device may turn up the pressure threshold of the electronic device.
With reference to the first aspect, in a possible design manner, the adjusting, by the electronic device, the pressure threshold of the electronic device may include: the electronic device lowers the pressure threshold of the electronic device by a first preset step. Wherein, the first preset step distance can be a smaller pressing pressure. For example, the first preset step distance may be any pressure value such as 2g, 3g or 5 g. The electronic device lowers the pressure threshold of the electronic device with a smaller pressing pressure (i.e., the first preset step), which may not have a greater impact on the user experience of fingerprint identification. The pressure threshold of the electronic device may be dynamically adjusted without the user's perception.
With reference to the first aspect, in another possible design manner, the adjusting, by the electronic device, the pressure threshold of the electronic device may include: the electronic device adjusts the pressure threshold of the electronic device to be the sum of the pressing pressure and the second preset step distance. Wherein the second preset step distance may be a smaller pressing pressure. For example, the second preset step distance may be any pressure value such as 2g, 3g, 5g or 6 g. In which the electronic device 100 increases the pressure threshold of the electronic device with a smaller pressing pressure (i.e., the second preset step distance), which may not have a great influence on the user's experience of fingerprint recognition. The pressure threshold of the electronic device may be dynamically adjusted without the user's perception.
With reference to the first aspect, in another possible design, if the user identity verification passes, the electronic device may adjust the pressure threshold, so as to reduce the possibility that the fingerprint information passes the user identity verification after the electronic device collects the fingerprint information next time. For example, it is assumed that the electronic device does not have a high parameter of fingerprint image quality of the fingerprint information collected this time, but can ensure that the user identity is verified. If the pressure threshold is reduced by the electronic equipment, the fingerprint information for the next user identity verification may be the fingerprint information input by the user with lower pressing pressure, and the parameter of the fingerprint image quality of the fingerprint information is lower than that of the fingerprint image quality of the fingerprint information acquired at this time. The electronic equipment adopts the fingerprint information to check the identity of the user, and the possibility that the identity of the user passes the check is low. Based on this situation, if the user identity authentication passes, the electronic device may first determine whether the electronic device satisfies a first preset condition. The electronic device may lower the pressure threshold of the electronic device if the electronic device does not satisfy the first preset condition.
Wherein the first preset condition includes at least one of the following conditions: the passing rate of the user identity verification performed by the electronic equipment is lower than or equal to a preset success rate threshold; the parameter of the fingerprint image quality of the fingerprint information is lower than or equal to a preset lower limit quality threshold; the pressure threshold of the electronic equipment is a preset lower limit pressure threshold. The electronic device meets a first preset condition, which may specifically be: the electronic device satisfies at least one of the first preset conditions.
For example, the first preset condition may include: the parameter of the fingerprint image quality of the fingerprint information is lower than or equal to a preset lower limit quality threshold. The electronic device meets a first preset condition, which may specifically be: the parameter of the fingerprint image quality of the fingerprint information is lower than or equal to a preset lower limit quality threshold. The electronic device does not satisfy the first preset condition, and specifically may be: the parameter of the fingerprint image quality of the fingerprint information is higher than the preset lower limit quality threshold.
For another example, the first preset condition may include: the passing rate of the user identity verification performed by the electronic equipment is lower than or equal to a preset success rate threshold; the parameter of the fingerprint image quality of the fingerprint information is lower than or equal to a preset lower limit quality threshold. The electronic device meets a first preset condition, which may specifically be: the passing rate of the user identity verification performed by the electronic equipment is lower than or equal to a preset power threshold; or the parameter of the fingerprint image quality of the fingerprint information is lower than or equal to a preset lower limit quality threshold; or, the passing rate of the user identity verification performed by the electronic equipment is lower than or equal to a preset success rate threshold, and the fingerprint image quality parameter of the fingerprint information is lower than or equal to a preset lower limit quality threshold. The electronic device does not satisfy the first preset condition, and specifically may be: the passing rate of the user identity verification of the electronic equipment is higher than a preset success rate threshold, and the fingerprint image quality parameter of the fingerprint information is higher than a preset lower limit quality threshold.
For another example, the first preset condition may include: the passing rate of the user identity verification performed by the electronic equipment is lower than or equal to a preset success rate threshold; the parameter of the fingerprint image quality of the fingerprint information is lower than or equal to a preset lower limit quality threshold; the pressure threshold of the electronic equipment is a preset lower limit pressure threshold. The electronic device meets a first preset condition, which may specifically be: the passing rate of the user identity verification performed by the electronic equipment is lower than or equal to a preset success rate threshold; or the parameter of the fingerprint image quality of the fingerprint information is lower than or equal to a preset lower limit quality threshold; or the pressure threshold of the electronic equipment is a preset lower limit pressure threshold; or the passing rate of the user identity verification performed by the electronic equipment is lower than or equal to a preset success rate threshold, and the parameter of the fingerprint image quality of the fingerprint information is lower than or equal to a preset lower limit quality threshold; or the passing rate of the user identity verification performed by the electronic equipment is lower than or equal to a preset success rate threshold, and the pressure threshold of the electronic equipment is a preset lower limit pressure threshold; or the parameter of the fingerprint image quality of the fingerprint information is lower than or equal to a preset lower limit quality threshold, and the pressure threshold of the electronic device is a preset lower limit pressure threshold. The electronic device does not satisfy the first preset condition, and specifically may be: the passing rate of the user identity verification of the electronic equipment is higher than a preset success rate threshold, the fingerprint image quality parameter of the fingerprint information is higher than a preset lower limit quality threshold, and the pressure threshold of the electronic equipment is not the preset lower limit pressure threshold.
With reference to the first aspect, in another possible design manner, if the user identity verification fails, the electronic device may increase a pressure threshold of the electronic device, which may affect user experience when the electronic device collects fingerprint information next time. For example, if the fingerprint information collected by the fingerprint sensor is not the correct fingerprint information, the user identity verification using the fingerprint information will not pass even if the electronic device turns the pressure threshold high. Moreover, after the pressure threshold is increased, the user needs to use a larger real-time pressing degree to ensure that the real-time pressing degree is greater than the increased pressure threshold when inputting fingerprint information next time, and user experience is affected. Based on this situation, if the user identity verification fails, the electronic device may first determine whether the electronic device satisfies the second preset condition. The electronic device may increase the pressure threshold of the electronic device if the electronic device does not satisfy the second preset condition.
Wherein the second preset condition comprises at least one of the following conditions: the parameter of the fingerprint image quality of the fingerprint information is higher than or equal to a preset upper limit quality threshold; the pressure threshold of the electronic equipment is a preset upper limit pressure threshold; the pressing pressure is greater than or equal to a preset upper limit pressure threshold value. The electronic device meets a second preset condition, which may specifically be: the electronic device satisfies at least one of the second preset conditions.
For example, the second preset condition may include: the parameter of the fingerprint image quality of the fingerprint information is higher than or equal to a preset upper limit quality threshold. The electronic device meeting the second preset condition may specifically be: the parameter of the fingerprint image quality of the fingerprint information is higher than or equal to a preset upper limit quality threshold. The electronic device not satisfying the second preset condition may be: the parameter of the fingerprint image quality of the fingerprint information is lower than a preset upper limit quality threshold.
For another example, the second preset condition may include: the parameter of the fingerprint image quality of the fingerprint information is higher than or equal to a preset upper limit quality threshold; the pressure threshold of the electronic equipment is a preset upper limit pressure threshold. The electronic device meeting the second preset condition may specifically be: the parameter of the fingerprint image quality of the fingerprint information is higher than or equal to a preset upper limit quality threshold; or the pressure threshold of the electronic equipment is a preset upper limit pressure threshold; or the parameter of the fingerprint image quality of the fingerprint information is higher than or equal to the preset upper limit quality threshold, and the pressure threshold of the electronic device is the preset upper limit pressure threshold.
The electronic device that does not satisfy the second preset condition may specifically be: the parameter of the fingerprint image quality of the fingerprint information is lower than a preset upper limit quality threshold, and the pressure threshold of the electronic device is not the preset upper limit pressure threshold.
For another example, the second preset condition may include: the fingerprint image quality parameter of the fingerprint information is higher than or equal to a preset upper limit quality threshold; the pressure threshold of the electronic equipment is a preset upper limit pressure threshold; the pressing pressure is greater than or equal to a preset upper limit pressure threshold value. The electronic device meeting the second preset condition may specifically be: the parameter of the fingerprint image quality of the fingerprint information is higher than or equal to a preset upper limit quality threshold; or the pressure threshold of the electronic equipment is a preset upper limit pressure threshold; or the pressing pressure is greater than or equal to a preset upper limit pressure threshold; or the parameter of the fingerprint image quality of the fingerprint information is higher than or equal to a preset upper limit quality threshold, and the pressure threshold of the electronic equipment is a preset upper limit pressure threshold; or the parameter of the fingerprint image quality of the fingerprint information is higher than or equal to a preset upper limit quality threshold, and the pressing pressure is greater than or equal to a preset upper limit pressure threshold; or the pressure threshold of the electronic device is a preset upper limit pressure threshold, and the pressing pressure is greater than or equal to the preset upper limit pressure threshold.
The electronic device that does not satisfy the second preset condition may specifically be: the fingerprint image quality parameter of the fingerprint information is lower than a preset upper limit quality threshold, the pressure threshold of the electronic equipment is not the preset upper limit pressure threshold, and the pressing pressure is smaller than the preset upper limit pressure threshold.
With reference to the first aspect, in another possible design manner, a lower limit value of the pressure threshold (i.e., a preset lower limit pressure threshold) is configured in advance in the electronic device. The preset lower limit pressure threshold is the lowest pressure threshold that can be set in the electronic device. If the electronic device lowers the pressure threshold of the electronic device and the pressure threshold of the electronic device is lower than the preset lower limit pressure threshold, the electronic device may set the pressure threshold of the electronic device to the preset lower limit pressure threshold.
With reference to the first aspect, in another possible design manner, an upper limit value of the pressure threshold (i.e., a preset upper limit pressure threshold) is preconfigured in the electronic device. The preset upper limit pressure threshold is the highest pressure threshold that can be set in the electronic device. If the pressure threshold of the electronic device is higher than the preset upper limit pressure threshold after the electronic device adjusts the pressure threshold of the electronic device, the electronic device may set the pressure threshold of the electronic device to the preset upper limit pressure threshold.
With reference to the first aspect, in another possible design manner, if the pressing pressure is smaller than a pressure threshold of the electronic device, the electronic device displays a prompt message on the first interface, where the prompt message is used to prompt the user to increase the pressing pressure when inputting the fingerprint information. After the user increases the pressing pressure, the pressing pressure collected by the pressure sensor is increased. When the pressing pressure acquired by the pressure sensor is greater than the pressure threshold value of the electronic equipment, the electronic equipment can carry out user identity verification.

And the fingerprint acquisition unit is used for acquiring fingerprint information input by a user on the first interface displayed by the display unit. And the pressure acquisition unit is used for acquiring the pressing pressure used when the user inputs the fingerprint information on the first interface displayed by the display unit.

Detailed Description
Generally, the pressure threshold of the electronic device is a fixed threshold that is set in advance. However, the quality of the fingerprint image of the fingerprint information collected by the fingerprint sensor is not completely determined by the pressing pressure of the user finger on the touch screen, and the depth of the fingerprint line of the user finger and the degree of dryness of the user finger also affect the quality of the fingerprint image. The depths of the fingerprint lines of different users are different, and the dryness and the humidity of the fingers are also different; different users may rely on pressure sensations to a different degree (e.g., some users prefer to press the touch screen with a greater force, while other users prefer to press the touch screen with a lesser force). Therefore, the user experience of the user in performing the identification of the fingerprint under the screen may be affected by determining the pressing pressure by using the preset pressure threshold (i.e., the fixed pressure threshold).
The embodiment of the application provides a method for adjusting a pressure threshold, and electronic equipment can dynamically adjust the pressure threshold of the electronic equipment, so that user experience of a user for identifying fingerprints under a screen can be improved. The method may be applied to an electronic device including a touch screen. A fingerprint sensor and a pressure sensor can be arranged below the touch screen. Alternatively, the touch screen integrates a fingerprint sensor and a pressure sensor. The fingerprint sensor is used for collecting fingerprint information input by a user on the touch screen. The pressure sensor is used for collecting the pressing pressure of a user on the touch screen when the fingerprint information is input by the touch screen.
The electronic equipment performs user identity verification on the fingerprint information acquired by the fingerprint sensor under the condition that the pressing pressure acquired by the pressure sensor is greater than or equal to the pressure threshold of the electronic equipment. That is to say, the pressure threshold value of the embodiment of the present application is used to determine whether the pressing pressure collected by the pressure sensor meets the requirement of the electronic device on the pressing pressure used when the user inputs fingerprint information.
Specifically, the electronic device may dynamically adjust the pressure threshold of the electronic device according to the fingerprint identification result, the fingerprint image quality of the fingerprint information, the size of the pressing pressure, and other parameters. Therefore, the setting mode of the pressure threshold of the fingerprint under the screen can be optimized, and the pressure threshold fixed in the electronic equipment is changed into the pressure threshold capable of being dynamically adjusted. The problems that the fixed pressure threshold requires that all users input fingerprint information, the user uses large pressing pressure to bring bad experience and the user identity verification consumes long time are solved, so that the adjusted pressure threshold can better accord with the fingerprint characteristics and pressing habits of the users, and the passing rate and the pressing effect of the user identity verification are considered.
The electronic device in the embodiment of the present application may be, for example, a portable computer (e.g., a mobile phone), a tablet computer, a notebook computer, a Personal Computer (PC), a wearable electronic device (e.g., a smart watch), an Augmented Reality (AR) \ Virtual Reality (VR) device, an in-vehicle computer, and the like, and the following embodiment does not particularly limit a specific form of the electronic device.
The parameters of the fingerprint image quality of the fingerprint information can be used for representing the quality of the fingerprint image. The quality of the fingerprint image can be represented by the definition or the integrity of the fingerprint image, and the quality of the fingerprint image can also be represented by the definition or the integrity of the fingerprint image. Wherein, the higher the definition of the fingerprint image is, the higher the quality of the fingerprint image is. The more complete the fingerprint image, the higher the quality of the fingerprint image. The higher the quality of the fingerprint image, the higher the parameters of the fingerprint image quality. When a user inputs fingerprint information on the touch screen, the larger the pressing pressure of the user on the touch screen is, the tighter the fit between the finger of the user and the touch screen is, and the higher the parameter of the fingerprint image quality of the fingerprint information acquired by the fingerprint sensor is. In this embodiment, the electronic device 100 may analyze the fingerprint information acquired by the fingerprint sensor of the electronic device 100 by using a preset image algorithm, and determine a parameter of the fingerprint image quality of the fingerprint information.
For example, assume that the electronic device is the cell phone 100 shown in fig. 1A. Take the example that the mobile phone 100 displays the screen locking interface 101 shown in (a) of fig. 1A. A fingerprint area 102 for inputting fingerprint information may be included in the lock screen interface 101. In the touch screen of the mobile phone 100, a fingerprint sensor and a pressure sensor are disposed at a position corresponding to the fingerprint area 102. Prompt information for prompting the user to input a fingerprint in the fingerprint area 102, such as "please input a fingerprint in the fingerprint area to unlock the screen! ". As shown in fig. 1A (b), the cellular phone 100 may receive a user input of fingerprint information in the fingerprint area 102. At this time, the fingerprint sensor may collect fingerprint information input by the user. The pressure sensor may capture a pressing pressure of the user against the touch screen when the user inputs fingerprint information in the fingerprint area 102. The user's pressure when inputting fingerprint information in the fingerprint area 102 is different, and the fingerprint image quality of the fingerprint information collected by the fingerprint sensor is different. For example, as shown in (b) of fig. 1A, the pressing pressure of the user on the touch screen may be X or Y, X < Y.
For example, when the pressing pressure of the user on the touch screen is X, the fingerprint image of the fingerprint information collected by the fingerprint sensor is the fingerprint image shown in (c) of fig. 1A. When the pressing pressure of the user on the touch screen is Y, the fingerprint image of the fingerprint information collected by the fingerprint sensor is the fingerprint image shown in (d) of fig. 1A. Wherein the definition of the fingerprint image shown in (d) of fig. 1A is higher than that of the fingerprint image shown in (c) of fig. 1A; and the fingerprint image shown in (d) of fig. 1A is more complete than the fingerprint image shown in (c) of fig. 1A. That is, the parameter of the fingerprint image quality of the fingerprint image shown in (d) of fig. 1A is higher than the parameter of the fingerprint image quality of the fingerprint image shown in (c) of fig. 1A.
In the embodiment of the present application, the unit of the pressing pressure and the pressure threshold may be newtons, abbreviated as cows, and the unit symbol is N. In physics, the gravity of an object is determined by using the formula G as mg. Wherein G is gravity, m is mass, G is constant, and G is about 9.8N/kg. That is, gravity is proportional to mass, so that the unit of mass m may be used as the unit of the pressing pressure and the pressure threshold value in this embodiment.

The motor 191 may generate a vibration cue. The motor 191 may be used for both an incoming call vibration prompt and a touch vibration feedback. For example, touch operations applied to different applications (e.g., photographing, audio playing, etc.) may correspond to different vibration feedback effects. The motor 191 may also respond to different vibration feedback effects for touch operations applied to different areas of the display screen 194. Different application scenes (such as time reminding, information receiving, alarm clock, game and the like) can also correspond to different vibration feedback effects. The touch vibration feedback effect may also support customization.
Indicator 192 may be an indicator light that may be used to indicate a state of charge, a change in charge, or a message, missed call, notification, etc.
The SIM card interface 195 is used to connect a SIM card. The SIM card can be attached to and detached from the electronic apparatus 100 by being inserted into the SIM card interface 195 or being pulled out from the SIM card interface 195. The electronic device 100 may support 1 or N SIM card interfaces, N being a positive integer greater than 1. The SIM card interface 195 may support a Nano SIM card, a Micro SIM card, a SIM card, etc. The same SIM card interface 195 can be inserted with multiple cards at the same time. The types of the plurality of cards may be the same or different. The SIM card interface 195 may also be compatible with different types of SIM cards. The SIM card interface 195 may also be compatible with external memory cards. The electronic device 100 interacts with the network through the SIM card to implement functions such as communication and data communication. In some embodiments, the electronic device 100 employs esims, namely: an embedded SIM card. The eSIM card can be embedded in the electronic device 100 and cannot be separated from the electronic device 100.
The embodiment of the present application provides a method for adjusting a pressure threshold, as shown in fig. 3, the method for adjusting a pressure threshold may include S301 to S306:
s301, the electronic device 100 displays a first interface.
When the electronic device 100 displays the first interface, fingerprint information input by the user on the first interface may be received, and the fingerprint information is used for user identity authentication.
Illustratively, the first interface may be a lock screen interface of the electronic device 100. For example, the first interface may be the lock screen interface 101 shown in (a) of fig. 1A.
Alternatively, the first interface may be an order payment interface of the electronic device 100. For example, the first interface may be an order payment interface 403 for panning shown in (b) of fig. 4. The electronic apparatus 100 displays an order payment interface 403 shown in (b) in fig. 4 in response to a user's click operation (e.g., a one-click operation) on an "immediate payment" button 402 in an order payment interface 401 of panning shown in (a) in fig. 4. The order payment interface 403 includes a fingerprint area 404. The fingerprint area 404 is used to input fingerprint information. Prompt information for prompting the user to enter a fingerprint in the fingerprint area 404, such as "please enter a fingerprint in the fingerprint area to complete payment! ".
Alternatively, the first interface may be an application login interface (i.e., an application unlock interface) of the electronic device 100. For example, the first interface may be the payroll unlocking interface 501 shown in fig. 5. Fingerprint area 502 is included in paymate unlock interface 501. The fingerprint area 502 is used for inputting fingerprint information. Prompt information for prompting the user to input a fingerprint in the fingerprint area 502, such as "please input a fingerprint in the fingerprint area to unlock the Payment application! ".
In this embodiment, the first interface includes, but is not limited to, the screen locking interface, the order payment interface, and the application login interface. The first interface in this embodiment may be any interface that may be used to receive fingerprint information input by a user for user identity authentication, for example, the interface may be a graphical user interface.
S302, the electronic device 100 collects fingerprint information input by the user on the first interface through the fingerprint sensor 180H, and collects pressing pressure of the user on the touch screen when the fingerprint information is input on the first interface through the pressure sensor 180A.
The fingerprint sensor 180H of the electronic device 100 may collect fingerprint information input by the user on the first interface. For example, the fingerprint sensor 180H may collect fingerprint information input by the user in the fingerprint area 102 in the first interface 101 shown in (b) of fig. 1A. For another example, the fingerprint sensor 180H may collect fingerprint information input by the user in the fingerprint area 404 in the first interface 403 shown in (b) of fig. 4. As another example, the fingerprint sensor 180H may collect fingerprint information input by the user in the fingerprint area 502 of the first interface 501 shown in fig. 5.
The pressure sensor 180A of the electronic device 100 may collect a pressing pressure of the user against the touch screen when the fingerprint information is input at the first interface. The pressing pressure may be a maximum pressing pressure of the user on the touch screen when the fingerprint information is input on the first interface.
S303, the electronic device 100 determines whether the pressing pressure collected by the pressure sensor 180A is greater than or equal to a pressure threshold of the electronic device 100.
Before the electronic device 100 leaves the factory, an initial pressure threshold may be configured in the electronic device 100. The initial pressure threshold may be a pressure threshold obtained by counting pressing pressures of a large number of users on the touch screen when the fingerprint information is input by the touch screen, and analyzing the quality of the fingerprint image of the fingerprint information input by using the corresponding pressing pressure and the user identity verification result. For most users, when the user inputs fingerprint information on the touch screen by using the pressing pressure greater than or equal to the initial pressure threshold, the fingerprint image quality of the fingerprint information acquired by the fingerprint sensor 180H can ensure that the user identity is verified. Of course, the premise of passing the user identity verification is that the user inputs fingerprint information using a correct finger.
If the electronic device 100 never adjusts the pressure threshold (i.e., the initial pressure threshold) of the electronic device 100, the pressure threshold of the electronic device 100 is the initial pressure threshold configured when the electronic device 100 is shipped. If the electronic device 100 adjusts the initial pressure threshold; then, the pressure threshold of the electronic device 100 is the adjusted pressure threshold of the electronic device 100. It should be noted that if the electronic device 100 adjusts the pressure threshold across the electronic device 100 multiple times; then, the pressure threshold of the electronic device 100 is the pressure threshold that the electronic device 100 has adjusted last time. For example, assuming that the initial pressure threshold of the electronic device 100 is 40g, the electronic device 100 adjusts the pressure threshold of the electronic device 100 twice, and increases the initial pressure threshold by 6g for the first time, so as to obtain a pressure threshold 46 g; the pressure threshold was adjusted a second time down by 5g, resulting in a pressure threshold of 41 g. At this time, the pressure threshold of the electronic apparatus 100 is 41 g.
It is understood that if the pressure sensor 180A senses a pressure greater than or equal to the pressure threshold of the electronic device 100, it indicates that the user's finger is more closely attached to the touch screen. In this case, the fingerprint image quality parameter of the fingerprint information collected by the fingerprint sensor 180H is relatively high. When the electronic device 100 performs the user identity verification using the fingerprint information, the possibility that the user identity verification passes is high. At this time, the electronic device 100 may perform user identity verification using the fingerprint information, that is, the electronic device 100 may perform S304.
If the pressure sensor 180A collects a pressure less than the pressure threshold of the electronic device 100, it indicates that the user's finger is not in close proximity to the touch screen. In this case, the parameter of the fingerprint image quality of the fingerprint information collected by the fingerprint sensor 180H is not so high. When the electronic device 100 performs the user identity verification by using the fingerprint information, the possibility that the user identity verification passes is not very high. At this time, the electronic device 100 does not perform user identity verification using the fingerprint information, and the electronic device 100 may discard (i.e., delete) the fingerprint information. The electronic device 100 may prompt the user to increase the pressing pressure when entering the fingerprint information. For example, it is assumed that the first interface described above is the first interface 101 shown in (b) in fig. 1A. The electronic device 100 receives fingerprint information input by a user in a fingerprint area 102 of the first interface 101. The pressure sensor 180A may capture a real-time pressing pressure of the user against the touch screen when the first fingerprint information is input in the fingerprint area 102. When the pressing pressure collected by the pressure sensor 180A is less than the pressure threshold of the electronic device 100, the electronic device 100 may display a prompt message "please increase the pressing pressure and input a fingerprint in the fingerprint area to unlock the screen! "601.
S304, the electronic device 100 performs user identity verification by using the fingerprint information.
If the user identity verification performed by the electronic device 100 using the fingerprint information passes, the parameter indicating the fingerprint image quality of the fingerprint information acquired by the fingerprint sensor 180H of the electronic device 100 is higher, so that the user identity verification can be guaranteed to pass. The higher parameter of the fingerprint image quality of the fingerprint information acquired by the fingerprint sensor 180H may be due to two reasons: (1) the fingerprint lines of the user are clear and are easy to collect; (2) the real-time pressing pressure used when the user inputs the fingerprint information is large, and the finger is tightly attached to the touch screen. Whether it is for reason (1) or reason (2), if the electronic device 100 properly lowers the pressure threshold, the fingerprint sensor 180H re-collects the fingerprint information of the user, and the electronic device 100 may pass the user identity verification using the fingerprint information re-collected by the fingerprint sensor 180H. Therefore, in this case, the electronic apparatus 100 can appropriately turn down the pressure threshold of the electronic apparatus 100. Specifically, if the electronic device 100 passes the user identity verification using the fingerprint information, the electronic device 100 may execute S305.
If the user identity is verified, the electronic device 100 may further display a graphical user interface corresponding to the first interface after the user identity is verified. For example, when the first interface is the screen locking interface 101 shown in (b) of fig. 1A, if the user identity verification is passed, the electronic device 100 (e.g., the mobile phone 100) may display the main interface (i.e., the desktop) of the mobile phone 100. The main interface includes icons of a plurality of applications. For another example, when the first interface is the order payment interface 403 of panning shown in (b) of fig. 4, if the user identity is verified, the electronic device 100 (e.g., the mobile phone 100) may display a prompt interface (not shown in the drawings) for successful payment.
If the user identity verification performed by the electronic device 100 using the fingerprint information is not passed, the following two reasons may be considered: (1) the user does not use the correct finger to input fingerprint information; (2) the fingerprint lines of the user are fuzzy and not easy to be collected, and the pressing pressure used when the user inputs the fingerprint information can not ensure that the fingerprint sensor 180H collects the fingerprint information with higher parameters of the fingerprint image quality. If the user id is not verified due to the reason (2), the electronic apparatus 100 appropriately increases the pressure threshold of the electronic apparatus 100, so that the possibility that the user id verification using the fingerprint information re-acquired by the fingerprint sensor 180H is passed can be increased. Therefore, in this case, the electronic device 100 may turn up the pressure threshold of the electronic device 100. Specifically, if the user identity verification performed by the electronic device 100 using the fingerprint information fails, the electronic device 100 may execute S306.
S305, the electronic device 100 reduces the pressure threshold of the electronic device 100.
In some embodiments, electronic device 100 may turn down the pressure threshold of electronic device 100 at a first preset pace. Wherein the first preset step distance may be a smaller pressing pressure. For example, the first preset step distance may be any pressure value such as 2g, 3g or 5 g. The electronic device 100 adjusts the pressure threshold of the electronic device 100 with a smaller pressing pressure (i.e., the first preset step distance), which does not have a larger influence on the user experience of fingerprint identification. That is, the pressure threshold of the electronic device 100 may be dynamically adjusted without the user's perception.
For example, it is assumed that the pressing pressure is 50g, the pressure threshold of the electronic device 100 is 45g, and the first preset step distance is 5 g. Since the pressing pressure 50g is greater than the pressure threshold 45g, the electronic device 100 may perform user identity verification using the fingerprint information collected by the fingerprint sensor 180H. If the user identity is verified, the electronic device 100 may decrease the pressure threshold 45g of the electronic device 100 by 5g, which is the first preset step size, to obtain the pressure threshold 40 g. At this time, the pressure threshold of the electronic apparatus 100 is 40 g.
In this embodiment, the lower limit value of the pressure threshold (i.e., the preset lower limit pressure threshold) is configured in advance in the electronic device 100. The preset lower limit pressure threshold is the lowest pressure threshold that can be set in the electronic device 100. If the adjusted pressure threshold of the electronic device 100 after performing S305 is lower than the preset lower limit pressure threshold, the electronic device 100 may set the pressure threshold of the electronic device to the preset lower limit pressure threshold.
S306, the electronic device 100 raises the pressure threshold of the electronic device 100.
In some embodiments, the electronic device 100 may adjust the pressure threshold of the electronic device 100 to be the sum of the above-mentioned pressing pressure and the second preset step distance. Wherein the second preset step distance may be a smaller pressing pressure. For example, the second preset step distance may be any pressure value such as 2g, 3g, 5g or 6 g. The electronic device 100 increases the pressure threshold of the electronic device 100 by a smaller pressing pressure (i.e., the second preset step distance), which does not have a larger influence on the user experience of fingerprint identification. That is, the pressure threshold of the electronic device 100 may be dynamically adjusted without the user's perception.
It should be noted that the second preset step distance may be the same as the first preset step distance. The second preset stride page may also be different from the first preset stride.
In connection with the above example, assume that the second predetermined step size is 6 g. Since the pressing pressure 50g is greater than the pressure threshold 45g, the electronic device 100 can perform the user identity verification using the fingerprint information collected by the fingerprint sensor 180H. If the user identity verification fails, the electronic device 100 may adjust the pressure threshold of the electronic device 200 to be the sum of the pressing pressure 50g and the second preset step 6 g. I.e. the adjusted pressure threshold is 56 g.
In this embodiment, when the pressure threshold of the electronic device 100 is increased for the electronic device 100, the second preset step distance may be added to the pressing pressure as a new pressure threshold.
In this embodiment, the user identity is verified on the premise that the pressing pressure is greater than the pressure threshold of the electronic device 100. That is, S304 is performed on the premise that the pressing pressure is greater than the pressure threshold of the electronic apparatus 100. That is, before the electronic apparatus 100 performs S306, the pressure threshold of the electronic apparatus 100 (i.e., the pressure threshold before adjustment) is smaller than the pressing pressure at which the user inputs the fingerprint information. Therefore, if the second preset step distance is added as a new pressure threshold value on the basis of the pre-adjustment pressure threshold value, the new pressure threshold value may also be smaller than the pressing pressure of the user to input the fingerprint information.
If the new pressure threshold is smaller than the above-mentioned pressing pressure, when the user inputs fingerprint information again using the same pressing pressure, the electronic device 100 may perform S304 for user identity verification using the fingerprint information collected by the fingerprint sensor 180H since the pressing pressure is greater than the new pressure threshold. However, if the user still inputs fingerprint information using the same pressing pressure; the quality of the fingerprint image of the fingerprint information acquired by the fingerprint sensor 180H is not improved compared to the quality of the fingerprint image of the fingerprint information acquired last time (i.e., before the pressure threshold is adjusted). It can be seen that if the second preset step distance is added to the pressure threshold before adjustment as a new pressure threshold, the new pressure threshold cannot be used to guide the user to increase the pressing pressure when inputting the fingerprint information, and thus the quality of the fingerprint image of the fingerprint information collected by the fingerprint sensor 180H may not be improved.
In the embodiment of the present application, a second preset step distance may be added as a new pressure threshold value on the basis of the pressing pressure of the user for inputting the fingerprint information. Wherein the new pressure threshold is greater than the pressing pressure. In this case, if the user inputs fingerprint information using the same pressing pressure again, the electronic apparatus 100 may determine that the pressing pressure is less than the new pressure threshold, and may prompt the user to increase the pressing pressure. If the pressing pressure is increased by the user, the degree of fitting of the finger of the user to the touch screen is increased, and the parameter of the fingerprint image quality of the fingerprint information acquired by the fingerprint sensor 180H is higher, so that the possibility that the user identity verification performed by the electronic device 100 is passed can be improved.
In this embodiment, the upper limit value of the pressure threshold (i.e., the preset upper limit pressure threshold) is configured in advance in the electronic device 100. The preset upper limit pressure threshold is the highest pressure threshold that can be set in the electronic device 100. If the adjusted pressure threshold of the electronic device 100 after performing S306 is higher than the preset upper limit pressure threshold, the electronic device 100 may set the pressure threshold of the electronic device to the preset upper limit pressure threshold.
The embodiment of the application provides a method for adjusting a pressure threshold, where the electronic device 100 may decrease the pressure threshold by a first preset step distance when the user identity passes verification; when the user identity verification fails, the pressure threshold of the electronic device 100 is adjusted to be the sum of the pressing pressure and the second preset step distance, that is, the pressure threshold is increased. That is, the electronic device 100 may dynamically adjust the pressure threshold, and improve the user experience of the user in performing the fingerprint recognition under the screen.
In some embodiments, if the user identity is verified, the electronic device 100 directly performs S305 to lower the pressure threshold, which may reduce the possibility that the fingerprint information passes the user identity verification after the electronic device 100 collects the fingerprint information next time. For example, it is assumed that the parameters of the fingerprint image quality of the fingerprint information acquired by the electronic device 100 this time are not very high, but the user identity verification can be guaranteed to pass. If the pressure threshold is lowered by the electronic device 100, the fingerprint information for the next user identity verification may be the fingerprint information input by the user with a lower pressing pressure, and the parameter of the fingerprint image quality of the fingerprint information is lower than that of the fingerprint image quality of the fingerprint information acquired this time. The electronic device 100 performs user identity verification by using the fingerprint information, and the possibility that the user identity verification passes is low.
Based on this situation, as shown in fig. 7, after S304, if the user identity is verified, before S305, the method of the embodiment of the present application may further include S701:
s701, the electronic device 100 determines whether the electronic device 100 satisfies a first preset condition.
Wherein, if the electronic device 100 does not satisfy the first preset condition, the electronic device 100 may perform S305. If the electronic device 100 satisfies the first preset condition, the electronic device 100 does not adjust the pressure threshold of the electronic device 100.
For example, the first preset condition may include at least one of the following conditions (1), (2), and (3):
condition (1): the passing rate of the user identity verification performed by the electronic device 100 is lower than or equal to a preset success rate threshold.
Condition (2): the parameter of the fingerprint image quality of the fingerprint information collected by the electronic device 100 is lower than or equal to the preset lower limit quality threshold.
Condition (3): the pressure threshold of the electronic device 100 (i.e., the pressure threshold of the electronic device 100 before S305 is executed) is the preset lower limit pressure threshold.
The electronic device 100 meets a first preset condition, which may specifically include: the electronic apparatus 100 satisfies at least one of the first preset conditions. For example, it is assumed that the first preset condition includes the above condition (1), condition (2), and condition (3). Then, if the electronic device 100 satisfies any one or any two or all three of the conditions (1), (2) and (3), the electronic device 100 satisfies a first preset condition. For another example, it is assumed that the first preset condition includes the condition (1) and the condition (3). Then, if the electronic apparatus 100 satisfies any one of the condition (1) and the condition (3), or both of the conditions, the electronic apparatus 100 satisfies a first preset condition.
For example, it is assumed that the first preset condition includes the above condition (1), condition (2), and condition (3). Then, if the electronic apparatus 100 does not satisfy the condition (1), and the electronic apparatus 100 does not satisfy the condition (2), and the electronic apparatus 100 does not satisfy the condition (3), the electronic apparatus 100 does not satisfy the first preset condition. For another example, it is assumed that the first preset condition includes the condition (1) and the condition (2). Then, if the electronic apparatus 100 does not satisfy the condition (1) and the electronic apparatus 100 does not satisfy the condition (2), the electronic apparatus 100 does not satisfy the first preset condition.
For example, in this embodiment, S701 is described by taking the example that the first preset condition includes the condition (1), the condition (2), and the condition (3). As shown in fig. 8, S701 shown in fig. 7 may include S801-S803:
s801, the electronic device 100 determines whether a passing rate of the user identity verification performed by the electronic device 100 is lower than or equal to a preset power threshold.
The electronic device 100 may count the total number of times of user identity verification performed by the electronic device 100 and the number of times of user identity verification passing; and calculating the ratio of the number of times of passing the user identity verification to the total number of times of performing the user identity verification, wherein the ratio is the passing rate of performing the user identity verification by the electronic equipment 100. For example, if the total number of user id checks performed by the electronic device is 10, and 7 user id checks in the 10 user id checks pass, the passing rate of the user id check performed by the electronic device 100 is 70%.
It should be noted that, when the electronic device 100 is used for the first time after being shipped from a factory, the initial value of the passing rate of the user identity verification performed by the electronic device 100 is 100%. After the electronic device 100 performs the user identity verification once, if the user identity verification passes, the passing rate of the user identity verification performed by the electronic device 100 is still 100%. If the user identity check is not passed, the passing rate of the user identity check performed by the electronic device 100 is 0.
It can be understood that if the passing rate of the user identity verification performed by the electronic device 100 is lower than or equal to the preset success rate threshold, it indicates that the passing rate of the user identity verification performed by the electronic device 100 is lower. In this case, if the electronic device 100 turns down the pressure threshold of the electronic device 100, the user identity verification performed by the electronic device 100 next time may fail. Therefore, as shown in fig. 8, after S801, if the passing rate of the user identity verification performed by the electronic device 100 is lower than or equal to the preset success rate threshold, the electronic device 100 does not adjust the pressure threshold.
If the passing rate of the user identity verification performed by the electronic device 100 is higher than the preset success rate threshold, it indicates that the passing rate of the user identity verification performed by the electronic device 100 is higher. In this case, it is not very likely that turning down the pressure threshold of the electronic device 100 will cause the next user identity verification by the electronic device 100 to fail. Then the electronic device 100 may attempt to adjust the low pressure threshold. If the passing rate of the user identity verification performed by the electronic device 100 is higher than the preset success rate threshold, the electronic device 100 may lower the pressure threshold of the electronic device 100. As shown in fig. 8, after S801, if the passing rate of the user identity verification performed by the electronic device 100 is higher than the preset success rate threshold, the electronic device 100 may perform S802:
s802, the electronic device 100 determines whether a parameter of the fingerprint image quality of the fingerprint information is lower than or equal to a preset lower quality threshold.
The preset lower limit quality threshold is a fingerprint image quality of a large amount of statistical fingerprint information, and the lower limit value of the parameter of the fingerprint image quality is determined by the result of user identity verification of a large amount of electronic equipment by adopting fingerprint information with different fingerprint image qualities.
It can be understood that if the user identity verification passes, the parameter of the fingerprint image quality of the fingerprint information adopted for the user identity verification is lower than or equal to the preset lower-limit quality threshold; in this case, if the electronic device 100 turns down the pressure threshold of the electronic device 100, the fingerprint information for the next user identity verification may be the fingerprint information input by the user with a lower pressing pressure, and the parameter of the fingerprint image quality of the fingerprint information is lower than that of the fingerprint image quality of the fingerprint information acquired this time. The electronic device 100 performs user identity verification by using the fingerprint information, and the possibility that the user identity verification passes is low. Therefore, as shown in fig. 8, after S802, if the parameter of the fingerprint image quality of the fingerprint information is lower than or equal to the preset lower limit quality threshold, the electronic device 100 does not adjust the pressure threshold.
If the user identity verification is passed, the parameter of the fingerprint image quality of the fingerprint information adopted for the user identity verification is higher than a preset lower limit quality threshold value; in this case, it is not very likely that turning down the pressure threshold of the electronic device 100 will cause the next user identity verification by the electronic device 100 to fail. Then the electronic device 100 may attempt to adjust the low pressure threshold. As shown in fig. 8, after S802, if the parameter of the fingerprint image quality of the fingerprint information is higher than the preset lower quality threshold, the electronic device 100 may perform S803:
s803, the electronic device 100 determines whether the pressure threshold of the electronic device 100 is a preset lower limit pressure threshold.
If the pressure threshold of the electronic device 100 is the preset lower limit pressure threshold, it indicates that the pressure threshold of the electronic device 100 is the lowest value of the pressure thresholds of the electronic device 100. In this case, the electronic device 100 does not need to readjust the pressure threshold of the electronic device 100. As shown in fig. 8, if the pressure threshold of the electronic device 100 is the preset lower limit pressure threshold, the electronic device 100 does not adjust the pressure threshold.
Since the preset lower limit pressure threshold is the lowest pressure threshold that can be set in the electronic device 100; therefore, if the pressure threshold of the electronic device 100 is not the preset lower limit pressure threshold, the pressure threshold of the electronic device 100 is greater than the preset lower limit pressure threshold. As shown in fig. 8, if the pressure threshold of the electronic device 100 is not the preset lower limit pressure threshold, the electronic device 100 may turn down the pressure threshold of the electronic device 100, i.e., the electronic device 100 may perform S305.
It is to be noted that one way in which the electronic apparatus 100 determines whether the electronic apparatus 100 satisfies the above-described condition (1), condition (2), and condition (3) is given in fig. 8 by way of example only. In the embodiment of the present application, the electronic device 100 is not limited to determine whether the electronic device 100 satisfies the sequence of the condition (1), the condition (2), and the condition (3). That is, in this embodiment of the application, the sequence of executing S801, S802, and S803 by the electronic device 100 is not limited.
For example, after S304, if the user identity is verified, the electronic device 100 may first perform S802; after S802, if the parameter of the fingerprint image quality of the fingerprint information is higher than the preset lower quality threshold, the electronic device 100 may perform S801; after S801, if the passing rate of the user identity verification performed by the electronic device 100 is higher than the preset success rate threshold, the electronic device may execute S803; after S803, if the pressure threshold of the electronic device 100 is not the preset lower limit pressure threshold, the electronic device 100 may perform S305.
For another example, after S304, if the user identity is verified, the electronic device 100 may first perform S802; after S802, if the parameter of the fingerprint image quality of the fingerprint information is higher than the preset lower quality threshold, the electronic device 100 may perform S803; after S803, if the pressure threshold of the electronic device 100 is not the preset lower limit pressure threshold, the electronic device may perform S801; after S801, if the passing rate of the user identity verification performed by the electronic device 100 is higher than the preset success rate threshold, the electronic device 100 may execute S305.
For another example, after S304, if the user identity is verified, the electronic device 100 may first perform S803; after S803, if the pressure threshold of the electronic device 100 is not the preset lower limit pressure threshold, the electronic device 100 may perform S801; after S801, if the passing rate of the user identity verification performed by the electronic device 100 is higher than the preset success rate threshold, the electronic device may perform S802; after S802, if the parameter of the fingerprint image quality of the fingerprint information is higher than the preset lower quality threshold, the electronic device 100 may perform S305.
It is to be noted that the first preset condition may include at least one of the following three conditions. For example, in some embodiments, the first preset condition may include only the condition (1) described above. In this embodiment, if the user identity check passes, the electronic device 100 may perform S801; after S801, if the passing rate of the user identity verification performed by the electronic device 100 is higher than the preset success rate threshold, the electronic device may directly perform S305.
In other embodiments, the first preset condition may include only the condition (2). In this embodiment, if the user identity check passes, the electronic device 100 may perform S802; after S802, if the parameter of the fingerprint image quality of the fingerprint information is higher than the preset lower quality threshold, the electronic device 100 may directly perform S305.
In other embodiments, the first preset condition may include the condition (1) and the condition (2). In this embodiment, if the user identity check passes, the electronic device 100 may perform S801; after S801, if a passing rate of the user identity verification performed by the electronic device 100 is higher than a preset success rate threshold, the electronic device 100 may execute S802; after S802, if the parameter of the fingerprint image quality of the fingerprint information is higher than the preset lower quality threshold, the electronic device 100 may directly perform S305.
In other embodiments, the first preset condition may include the condition (2) and the condition (3). In this embodiment, if the user identity check passes, the electronic device 100 may perform S803; after S803, if the pressure threshold of the electronic device 100 is not the preset lower limit pressure threshold, the electronic device 100 may perform S802; after S802, if the parameter of the fingerprint image quality of the fingerprint information is higher than the preset lower quality threshold, the electronic device 100 may directly perform S305.
In some embodiments, if the user identity verification fails, the electronic device 100 directly performs S306 to raise the pressure threshold of the electronic device 100, which may affect the user experience when the electronic device 100 next acquires fingerprint information. For example, if the fingerprint information collected by the fingerprint sensor 180H is not the correct fingerprint information, the user identity check using the fingerprint information will not pass even if the electronic device 100 turns the pressure threshold high. Moreover, after the pressure threshold is increased, the user needs to use a larger real-time pressing degree to ensure that the real-time pressing degree is greater than the increased pressure threshold when inputting fingerprint information next time, and user experience is affected.
Based on this situation, as shown in fig. 7, after S304, if the user identity check fails, before S306, the method of this embodiment of the application may further include S702:
s702, the electronic device 100 determines whether the electronic device 100 satisfies a second preset condition.
Wherein, if the electronic device 100 does not satisfy the second preset condition, the electronic device 100 may perform S306. If the electronic device 100 satisfies the second preset condition, the electronic device 100 does not adjust the pressure threshold of the electronic device 100.
For example, the second preset condition may include at least one of the following conditions (4), (5), and (6):
condition (4): the parameter of the fingerprint image quality of the fingerprint information collected by the electronic device 100 is higher than or equal to the preset upper limit quality threshold.
Condition (5): the pressure threshold of the electronic apparatus 100 (i.e. the pressure threshold of the electronic apparatus 100 before S306 is executed) is the preset upper limit pressure threshold.
Condition (6): the pressing pressure collected by the pressure sensor 180A of the electronic device 100 is greater than or equal to a preset upper pressure limiting threshold.
The electronic device 100 meets a second preset condition, which may specifically include: the electronic apparatus 100 satisfies at least one of the second preset conditions. For example, it is assumed that the second preset condition includes the condition (4), the condition (5), and the condition (6). Then, if the electronic device 100 satisfies any one or any two or all three of the conditions (4), (5) and (6), the electronic device 100 satisfies a second preset condition. For another example, it is assumed that the second preset condition includes the condition (4) and the condition (6). Then, if the electronic apparatus 100 satisfies any one of the condition (4) and the condition (6), or both of the conditions, the electronic apparatus 100 satisfies a second preset condition.
For example, it is assumed that the second preset condition includes the condition (4), the condition (5), and the condition (6). Then, if the electronic apparatus 100 does not satisfy the condition (4), and the electronic apparatus 100 does not satisfy the condition (5), and the electronic apparatus 100 does not satisfy the condition (6), the electronic apparatus 100 does not satisfy the second preset condition. For another example, it is assumed that the second preset condition includes the condition (4) and the condition (5). Then, if the electronic apparatus 100 does not satisfy the condition (4) and the electronic apparatus 100 does not satisfy the condition (5), the electronic apparatus 100 does not satisfy the second preset condition.
For example, the present embodiment will describe S702 by taking the second preset condition as an example, where the second preset condition includes the condition (4), the condition (5), and the condition (6). As shown in fig. 8, S702 shown in fig. 7 may include S901-S903:
s901, the electronic device 100 determines whether a parameter of the fingerprint image quality of the fingerprint information acquired by the electronic device 100 is higher than or equal to a preset upper quality threshold.
The preset upper limit quality threshold is the upper limit value of the parameter of the fingerprint image quality determined by counting the fingerprint image quality of a large amount of fingerprint information and the result of user identity verification of a large amount of electronic equipment by adopting the fingerprint information with different fingerprint image qualities.
It can be understood that, if the user identity verification fails, but the parameter of the fingerprint image quality of the fingerprint information used for performing the user identity verification this time is higher than or equal to the preset upper quality threshold, it may be because the fingerprint information input by the user is not correct fingerprint information. That is, the fingerprint information collected by the fingerprint sensor 180H does not match the fingerprint information that is pre-entered in the electronic device 100 for user identity verification. In this case, even if the electronic apparatus 100 raises the pressure threshold, the user identification check using the fingerprint information does not pass. Moreover, after the pressure threshold is increased, the user needs to use a larger real-time pressing degree to ensure that the real-time pressing degree is greater than the increased pressure threshold when inputting fingerprint information next time, so that the user experience is influenced. Therefore, as shown in fig. 8, after S901, if the parameter of the fingerprint image quality of the above fingerprint information acquired by the electronic device 100 is higher than or equal to the preset upper quality threshold, the electronic device 100 does not adjust the pressure threshold.
If the user identity verification fails, but the parameter of the fingerprint image quality of the fingerprint information used for the user identity verification is lower than the preset upper quality threshold, the fitting degree between the finger and the touch screen may be poor due to the small pressing pressure used when the user inputs the fingerprint information, and the fingerprint sensor 180H may not acquire the fingerprint information with the higher parameter of the fingerprint image quality. In this case, in order to improve the parameter of the fingerprint image quality of the fingerprint information collected by the fingerprint sensor 180H, the electronic apparatus 100 may increase the pressure threshold of the electronic apparatus 100 to guide the user to input the fingerprint information using a larger pressing pressure. As shown in fig. 8, after S901, if the parameter of the fingerprint image quality of the above fingerprint information collected by the electronic device 100 is lower than the preset upper quality threshold, the electronic device 100 may execute S902:
s902, the electronic device 100 determines whether the pressure threshold of the electronic device 100 is a preset upper limit pressure threshold.
If the pressure threshold of the electronic device 100 is the preset upper limit pressure threshold, it indicates that the pressure threshold of the electronic device 100 is already the maximum value of the pressure threshold of the electronic device 100. In this case, the electronic device 100 does not need to increase the pressure threshold of the electronic device 100.
Since the preset upper limit pressure threshold is the highest pressure threshold that can be set in the electronic device 100; therefore, if the pressure threshold of the electronic device 100 is not the preset upper limit pressure threshold, the pressure threshold of the electronic device 100 is smaller than the preset upper limit pressure threshold. In this case, the electronic device 100 may turn up the pressure threshold of the electronic device 100. As shown in fig. 8, after S902, if the pressure threshold of the electronic device 100 is not the preset upper limit pressure threshold, the electronic device 100 may perform S903:
s903, the electronic device 100 determines whether the pressing pressure is greater than or equal to a preset upper limit pressure threshold.
If the pressing pressure is greater than or equal to the preset upper limit pressure threshold, it indicates that the user has input fingerprint information using the pressing pressure greater than or equal to the preset upper limit pressure threshold. In this case, the user identity verification is not passed, and the reason why the user identity verification is not passed is not that the pressing pressure used when the user inputs the fingerprint information is small. In this case, the electronic device 100 does not need to raise the pressure threshold of the electronic device 100.
If the pressing pressure is smaller than the preset upper limit pressure threshold, it indicates that the pressing pressure used when the user inputs the fingerprint information is not the upper limit value of the pressure threshold of the electronic device 100. In this case, in order to improve a parameter of the fingerprint image quality of the fingerprint information collected by the fingerprint sensor 180H, the electronic apparatus 100 may increase the pressure threshold of the electronic apparatus 100 to guide the user to input the fingerprint information using a large pressing pressure. As shown in fig. 8, after S903, if the pressing pressure is less than the preset upper limit pressure threshold, the electronic device 100 may perform S306.
It is to be noted that one way in which the electronic apparatus 100 determines whether the electronic apparatus 100 satisfies the above-described condition (4), condition (5), and condition (6) is given in fig. 8 by way of example only. In the embodiment of the present application, the electronic device 100 is not limited to determine whether the electronic device 100 satisfies the sequence of the condition (4), the condition (5), and the condition (6). That is, in this embodiment of the application, the sequence of executing S901, S902, and S903 by the electronic device 100 is not limited.
For example, after S304, if the user identity verification fails, the electronic device 100 may first perform S902; after S902, if the pressure threshold of the electronic device 100 is not the preset upper limit pressure threshold, the electronic device 100 may execute S901; after S901, if the parameter of the fingerprint image quality of the fingerprint information is lower than the preset upper quality threshold, the electronic device may execute S903; after S903, if the pressing pressure is smaller than the preset upper limit pressure threshold, the electronic device 100 may execute S306.
For another example, after S304, if the user identity verification fails, the electronic device 100 may first perform S901; after S901, if the parameter of the fingerprint image quality of the fingerprint information is lower than the preset upper quality threshold, the electronic device may execute S903; after S903, if the pressing pressure is smaller than the preset upper limit pressure threshold, the electronic device 100 may execute S902; after S902, if the pressure threshold of the electronic device 100 is not the preset upper limit pressure threshold, the electronic device 100 may perform S306.
For another example, after S304, if the user identity verification fails, the electronic device 100 may first perform S903; after S903, if the pressing pressure is smaller than the preset upper limit pressure threshold, the electronic device 100 may execute S901; after S901, if the parameter of the fingerprint image quality of the fingerprint information is lower than the preset upper quality threshold, the electronic device may execute S902; after S902, if the pressure threshold of the electronic device 100 is not the preset upper limit pressure threshold, the electronic device 100 may perform S306.
It is to be noted that the second preset condition may include at least one of the following three conditions. For example, in some embodiments, the second preset condition may include only the condition (4). In this embodiment, if the user identity verification fails, the electronic device 100 may perform S901; after S901, if the parameter of the fingerprint image quality of the fingerprint information acquired by the electronic device 100 is lower than the preset upper quality threshold, the electronic device may directly perform S306.
In other embodiments, the second preset condition may include only the condition (5). In this embodiment, if the user identity check fails, the electronic device 100 may perform S902; after S902, if the pressure threshold of the electronic device 100 is not the preset upper limit pressure threshold, the electronic device 100 may directly perform S306.
In other embodiments, the second preset condition may include the condition (4) and the condition (5). In this embodiment, if the user identity verification fails, the electronic device 100 may perform S901; after S901, if the parameter of the fingerprint image quality of the fingerprint information acquired by the electronic device 100 is lower than the preset upper quality threshold, the electronic device 100 may execute S902; after S902, if the pressure threshold of the electronic device 100 is not the preset upper limit pressure threshold, the electronic device 100 may directly perform S306.
In other embodiments, the second preset condition may include the condition (4) and the condition (6). In this embodiment, if the user identity verification fails, the electronic device 100 may perform S901; after S901, if the parameter of the fingerprint image quality of the fingerprint information collected by the electronic device 100 is lower than the preset upper quality threshold, the electronic device 100 may execute S903; after S903, if the pressing pressure is smaller than the preset upper limit pressure threshold, the electronic device 100 may execute S306.
The embodiment of the application provides a method for adjusting a pressure threshold, and an electronic device 100 can dynamically adjust the pressure threshold according to a user identity verification result of fingerprint information, a parameter of fingerprint image quality of the fingerprint information, a size of pressing pressure and other parameters, so that the adjusted pressure threshold can better accord with fingerprint characteristics and pressing habits of a user.
