Detailed ways

In order to make the objects, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

The terminal involved in the embodiment of the present application is a touch terminal using a touch display screen. The touch display screen is a simple, convenient and natural human-computer interaction device, which has a user interface for receiving a touch operation of the touch display screen, detecting the touch operation, and displaying various applications installed on the terminal. In the embodiment of the present application, a fingerprint identification module is disposed under the touch display screen of the terminal, and thus the terminal further has a fingerprint recognition function. The terminal can collect fingerprints through the fingerprint recognition module, identify the collected fingerprints, and perform corresponding functions based on the fingerprints.

2 is a flowchart of a method for opening a fingerprint identification function according to an embodiment of the present application. As shown in FIG. 2, the method for opening a fingerprint identification function includes the following steps:

Step 201: Detect whether the terminal is in a designated state.

The specified state refers to a state in which fingerprint entry is required to trigger the next processing, that is, the specified state is a state in which fingerprint identification is required. In a possible implementation manner, the specified state is a lock screen state; in another possible implementation manner, the specified state is a state in which the current display interface of the terminal is a fingerprint entry interface.

The fingerprint identification function opening method provided in the embodiment of the present application is applied to the terminal in the non-off state when the terminal is in the power-off state and does not respond to the touch operation of the touch display screen. The non-off state includes a lock screen state and a non-lock screen state.

The lock screen status means that the terminal is in an unlocked state. The non-lock screen state means that the terminal is in an unlocked state. When the terminal is in the non-lock screen state, it is also necessary to open the fingerprint input interface to trigger the fingerprint recognition function. The fingerprint input interface refers to a user interface that needs to input a fingerprint for identity authentication in each application installed on the terminal to complete the corresponding function. The fingerprint entry interface may include a fingerprint payment interface, an object unlock interface, and the like. The fingerprint payment interface refers to an interface that needs to enter a fingerprint for identity authentication to complete a payment function; the object unlock interface refers to an interface that needs to input a fingerprint for identity authentication to unlock an object in the terminal, and the object may be an application in the terminal. It can also be a folder in the terminal, or it can be an interface of the application in the terminal.

Taking the fingerprint input interface as the fingerprint payment interface as an example, an application of the terminal needs fingerprint identification when performing payment, and the terminal displays the fingerprint input interface of the application, that is, a payment interface, to prompt the user to input a fingerprint for identity authentication. When the user enters a fingerprint and the identity authentication is successful, the terminal performs a payment function.

In combination with the specific implementation of the foregoing specified state, step 201 can be implemented as follows: when the specified state is the lock screen state, the terminal determines whether the terminal is in the designated state by detecting whether the lock screen interface is displayed. If it is detected that the terminal displays the lock screen interface, the terminal is in the specified state; if it is detected that the terminal does not display the lock screen interface, the terminal is not in the designated state. The lock screen interface may be set by default by the terminal, or may be customized by the user. This embodiment of the present application does not limit this.

In combination with the specific implementation of the foregoing specified state, the step 201 may be implemented as follows: when the specified state is the state in which the current display interface of the terminal is the fingerprint input interface, the terminal determines whether the terminal is determined by determining whether the current display interface includes a preset keyword. Is in the specified state. If it is determined that the current display interface includes the preset keyword, the terminal is in the specified state; if it is determined that the current display interface does not include the preset keyword, it is determined that the terminal is not in the designated state. The foregoing preset keywords may include “payment”, “payment”, “order”, “transfer”, and the like, which are not limited in the embodiment of the present application.

When the terminal is in the specified state, the following steps 202 to 203 may be performed, and the following steps 202 to 205 may be performed, and the following steps 206 to 207 may also be performed, which are not limited in this embodiment of the present application.

Step 202: If the terminal is in the designated state and the holding operation is detected, determining a holding gesture of the holding operation, and predicting a touch landing area corresponding to the holding gesture.

The holding gesture refers to a gesture used by the user to perform a holding operation on the terminal. The grip gesture can include a left hand grip, a right hand grip, and a two-hand grip. The touch drop area refers to an area where the contact probability between the user's finger and the touch display screen is greater than a preset probability when the user touches the touch display screen. In addition, the shape and the area of the touch landing area are not limited in the embodiment of the present application.

In order to detect the holding operation, a thermal sensor may be disposed at the edge of the terminal. Since the human body temperature is different from the temperature of the terminal, the temperature sensor may be sensed by the thermal sensor to detect whether there is a temperature change, thereby detecting whether there is a holding operation. Thereafter, the terminal further determines the determined touch drop area corresponding to the grip gesture according to the grip gesture of the grip operation.

When the terminal detects the holding operation, the position, shape, and area of the contact area of the current user's hand and the edge of the terminal may be detected by the thermal sensor, thereby analyzing the current holding gesture of the user.

In a possible implementation manner, when the terminal detects that the difference between the first contact area and the second contact area is greater than a preset threshold, and the first contact area is greater than the second contact area, determining the current holding gesture Hold for the left hand. The first contact area refers to the area of the contact area of the user's hand and the left side, and the second contact area refers to the area of the contact area of the user's hand and the right side. The preset threshold may be set according to actual requirements, which is not limited in this embodiment of the present application.

In another possible implementation manner, when the terminal detects that the difference between the first contact area and the second contact area is greater than a preset threshold, and the first contact area is smaller than the second contact area, determining the current hold The gesture is held by the right hand.

In another possible implementation manner, when the terminal detects that the difference between the first contact area and the second contact area is less than a preset threshold, and the first contact area is smaller than the second contact area, determining the current grip Gestures are held by both hands.

Since the touch gesture area of the touch display screen of the user may be different when the user's grip gesture is different, the touch drop area of the touch operation of the touch display screen may be determined according to the grip gesture. .

In an actual implementation, when the touch drop area of the touch operation on the touch display screen is determined according to the holding gesture, the following two methods may be used:

In a first possible implementation manner, according to the holding gesture, a user's finger landing range is predicted, and the finger landing range is determined as a touch landing area.

In a possible implementation manner, according to the holding gesture, when the terminal predicts the user's finger landing range, the terminal may use the starting point of the contact position as the center according to the contact position of the hand and the terminal touching the display screen and the preset finger length. The sector area having the radius of the preset finger is determined as the finger drop range of the user. When the user needs to perform a touch operation, the user's tiger mouth will press to the terminal touch display screen, and the contact position between the tiger mouth and the terminal touch display screen is the touch position between the hand and the terminal touch display screen. The preset finger length may be the system default or may be preset by the user according to the length of his finger. The system default preset finger length can be obtained based on feedback from general users. Of course, the angle of the sector area can also be set according to the user's own usage habits.

The first way may have the following three scenarios in the specific implementation:

When the holding gesture indicates that the current terminal is held by the user's left hand, it is possible to predict an area where the user's left hand finger may fall on the touch display screen, that is, the user's left hand finger drop point range, and determine the left hand finger drop point range as a touch. Falling area; or,

When the holding gesture indicates that the current terminal is held by the right hand of the user, it may be predicted that the right hand finger of the user may fall on the area on the touch display screen, that is, the right hand finger drop range of the user, and the right hand finger drop point range is determined as a touch. Falling area; or,

When the holding gesture indicates that the user is currently being held by both hands of the user, it is possible to predict an area where the user's two-handed finger may fall on the touch display screen, that is, the user's two-hand finger landing range, and the left-hand finger may fall within the range, or The range of the right hand finger drop point, or the left hand and right hand finger drop point range is determined as the touch drop point area.

When the holding gesture indicates that the current terminal is held by the user's hands, in actual implementation, the dominant hand may be set according to the user's own usage habits, and the user's dominant finger drop point range is determined as the touch landing area.

In a second manner, according to the holding gesture and the touch operation record, the area of the touch operation record in which the number of touch operations corresponding to the holding gesture is greater than the first preset threshold is determined as the touch landing area.

The terminal can record the holding gesture, the area of the touch operation, and the corresponding function of the touch operation when the user performs a touch operation on the touch display screen, and obtain a touch operation record. The terminal may also perform a classification and statistics on the touch operation according to the recorded holding gesture, obtain an area of the touch operation corresponding to each holding gesture, and the number of touch operations performed in each area. The terminal may query the touch operation record corresponding to the current holding gesture in the touch operation record based on the grip gesture obtained by the analysis, so that the area of the touch operation corresponding to the current holding gesture is greater than the first preset threshold, and the The area is determined to be a touch drop area.

For example, when the holding gesture indicates that the current terminal is held by the user's left hand, the terminal may query the touch operation record to record the touch operation when the terminal is held by the user's left hand, and in the query result, the number of touch operations is greater than the first A region of a predetermined threshold is determined as a touch drop region. When the holding gesture indicates that the current terminal is held by the user's right hand and is held by the user's two hands, the step of the terminal to perform the query to determine the touch landing area is the same as the above-mentioned holding by the user's left hand. Make a statement.

Referring to FIG. 3, a schematic diagram of an interface of a touch drop area provided by an embodiment of the present application is shown. The terminal is held by the user's left hand, and the terminal determines that the left hand holds the corresponding touch drop area 31.

When the terminal is not in the specified state, that is, the terminal does not have the fingerprint identification requirement, the terminal puts the fingerprint recognition module set under the touch display screen into a sleep state, and when the fingerprint recognition module is in the sleep state, the fingerprint recognition The module does not fingerprint and recognize the user's touch operation on the touch display screen. In the above manner, the fingerprint recognition module can be prevented from being always in the working state, thereby saving power consumption of the terminal.

Step 203: The terminal starts the fingerprint recognition function of the touch landing area corresponding to the holding gesture.

Since the terminal supports full-screen fingerprint recognition, the user can perform touch operation on any area of the touch display screen for fingerprint input, and when the terminal needs to perform fingerprint input, the full-screen fingerprint recognition function is turned on, which may cause large power consumption. . In order to reduce the power consumption, the touch drop area of the touch operation of the touch display screen can be determined, so that only the fingerprint recognition function of the touch drop area is turned on.

When an application of the terminal needs to perform fingerprint recognition, the fingerprint recognition function of the touch drop area of the user performing the touch operation may be turned on, so that the fingerprint of the user is collected in the touch drop area, and the collected fingerprint is collected. The feature points are compared with the preset fingerprints to complete fingerprint recognition. In this way, only the fingerprint recognition function of the touch landing area of the touch operation is opened, which effectively avoids the problem of large power consumption caused by the full screen opening fingerprint recognition function, reduces the power consumption of the terminal, and prolongs the service life of the terminal hardware.

Optionally, after the terminal starts the fingerprint recognition function of the touch drop area, the prompt information may be generated, where the prompt information is used to prompt the user to perform fingerprint input in the touch drop area. Illustratively, the terminal frame selects the touch drop area described above to prompt the user to enter the location of the fingerprint. In the above manner, it is possible to prevent the occurrence of fingerprint collection failure when the user touches other locations outside the touch point area, and the success rate of fingerprint collection is improved.

In a specific implementation, the touch drop area determined by the embodiment shown in FIG. 2 is different from the actual touch area of the touch display screen performed by the user. For example, when the terminal is actually used, the user may also Holding the terminal, the finger of the other hand touches the touch display screen, and the touch drop area of the fingerprint recognition function is deviated from the actual one, so that the terminal does not detect the touch operation in the touch drop area, and A situation in which a touch operation on other areas of the touch display screen is detected occurs. In this case, after the terminal turns on the fingerprint recognition function of the touch drop area determined according to the holding gesture, the user's fingerprint cannot be collected and recognized. , which causes authentication to fail.

In an optional embodiment provided by the embodiment shown in FIG. 2, the method for opening the fingerprint identification function may further include the method for enabling the fingerprint identification function to be included in the foregoing embodiment. The following steps:

Step 204: When the first touch operation of the touch landing area corresponding to the holding posture is not detected within the preset time length, and the second touch operation of the other area is detected, according to the pressure of the second touch operation a value that determines a touch drop area of the second touch operation.

The preset duration can be set according to actual requirements, which is not limited in this embodiment of the present application. Illustratively, the preset duration is 2 seconds. The other area is an area other than the touch drop area corresponding to the grip gesture in the touch display screen.

Optionally, determining the touch landing area of the second touch operation is implemented as the following sub-steps according to the pressure value of the second touch operation:

Step 204a, measuring a pressure value of the second touch operation;

The pressure value is used to measure the magnitude of the pressure of the second touch operation of the user acting on the other areas described above. The terminal measures the pressure value of the touch operation through the pressure sensor, so that the pressure value can be compared with the second preset threshold to determine whether the current touch operation is a touch operation for fingerprint recognition.

In a possible implementation manner, when the terminal detects a touch operation on the touch display screen, the varistor in the pressure sensor provided on the terminal may deform along with the touch operation, and the pressure is caused by the deformation. The resistance value of the varistor changes, so that the pressure value of the current touch operation can be measured according to the current or voltage change.

In a possible implementation manner, when the terminal detects a touch operation on the touch display screen, the diaphragm in the pressure sensor provided on the terminal may be displaced along with the touch operation, and the film is displaced due to the displacement The resistance value of the chip changes so that the pressure value of the current touch operation can be measured according to the current or voltage change.

The above-mentioned implementations can be used to measure the pressure value of the touch operation performed by the user on the touch display screen by the pressure sensor. Of course, there may be other types of pressure sensors in the actual implementation, which is not limited in the embodiment of the present application.

Step 204b, when the pressure value of the second touch operation is greater than the second preset threshold, acquiring coordinates of the pressure center point of the second touch operation;

The second preset threshold may be set according to the user's usage habits. The second preset threshold determines the function setting of the touch operation. When the pressure value of the touch operation is greater than or less than or equal to the second preset threshold, the touch operation may correspond to a different function. The pressure center point may be the geometric center of the touch position corresponding to the second touch operation, or may be the point with the largest pressure value.

In the embodiment of the present application, the pressure value of the touch operation is greater than the second preset threshold, which may be used as a judgment condition for the fingerprint recognition function to be enabled when the terminal needs to perform fingerprint recognition. When the terminal measures the pressure value of the touch operation, the coordinates of the pressure center point of the touch operation may be acquired, and the pressure center point may be the maximum deformation point or the maximum displacement point caused by the touch operation, or may be the touch operation. The point of action of stress. Since the pressure center point is generally located at the center position of the user's fingerprint, the coordinates of the pressure center point of the touch operation can be acquired, and based on the coordinates of the pressure center point, the touch drop area of the touch operation is determined. The terminal receives the touch operation, measures the pressure value of the touch operation, and analyzes the pressure of the touch operation, and obtains the coordinates of the pressure center point of the pressure.

In step 204c, an area centered on the coordinates of the pressure center point and having an area of a predetermined area is determined as a touch drop area of the second touch operation.

The second preset threshold may be set according to actual requirements, which is not limited by the embodiment of the present application. The preset area may be determined according to the area of the fingerprint image to be collected, which is not limited in this embodiment of the present application. In addition, the area and shape of the touch drop area of the second touch operation are not limited in the embodiment of the present application. In the embodiment of the present application, the terminal may determine the area centered on the coordinate of the pressure center point and the area of the preset area as the touch drop area. After researching and analyzing the fingerprint of the user, it is concluded that the size of the fingerprint is generally less than 1 square centimeter (cm ² ), and thus the predetermined area can be referenced by 1 cm ² in a specific implementation. The touch landing area may be a circular area, and may be other shape areas, which is not limited in this application.

Step 205: Turn on the fingerprint recognition function of the touch drop area of the second touch operation.

If the user does not perform fingerprint entry in the touch drop area corresponding to the predicted grip posture, but touches other areas than the touch drop area corresponding to the grip gesture, the terminal re-determines the touch drop area. And the fingerprint identification function of the newly determined touch drop area is turned on, thereby reducing the number of failures of the terminal fingerprint recognition, and improving the practicability of the fingerprint recognition function of the terminal. In addition, the terminal can also turn off the fingerprint recognition function of the touch landing area corresponding to the holding gesture to save power consumption of the terminal.

When the user enters the fingerprint, the terminal may not be gripped. For example, the terminal is placed on the table, and the fingerprint recognition function of how to accurately turn on the partial area in the touch display screen will be explained below.

Step 206: If the terminal is in the specified state, and the holding operation is not detected, and the third touch operation on the touch display screen is detected, determining the third touch operation according to the pressure value of the third touch operation. Touch the drop area.

The user can place the terminal on other objects (such as a table) and perform a touch operation on the touch display screen of the terminal. At this time, the terminal does not detect the grip operation, and detects the touch on the touch display screen. During operation, the terminal cannot determine the touch drop area of the touch operation on the touch display screen according to the user's holding gesture, and the touch operation may be analyzed, and the touch of the touch operation is determined according to the pressure value of the touch operation. The landing area is opened, and the fingerprint recognition function of the touch drop area of the touch operation is turned on to implement identity authentication.

A pressure sensor can be arranged under the touch display of the terminal. When the user touches the touch display, the pressure sensor provided by the terminal can measure the pressure value of the touch operation based on the deformation or the displacement amount. When the pressure value of the touch operation is different, the function corresponding to the touch operation may be different. The terminal may determine the function corresponding to the touch operation based on different pressure values, and respond to the touch operation to implement the corresponding function.

The terminal determines, according to the pressure value of the touch operation, the specific implementation of the touch drop area of the touch operation as the following sub-steps:

Step 206a, measuring a pressure value of the third touch operation;

Step 206b, when the pressure value of the second touch operation is greater than the third preset threshold, acquiring coordinates of the pressure center point of the third touch operation;

In step 206c, the area centered on the coordinate of the pressure center point of the third touch operation and the area of the preset area is determined as the touch drop area of the third touch operation.

The explanation of steps 206a to 206c can refer to steps 204a to 204c. I will not repeat them here.

Step 207, the fingerprint recognition function of the touch landing area of the third touch operation is turned on.

If the user does not perform the holding operation on the terminal, but directly touches the touch display screen, the terminal determines the touch landing area according to the received touch operation, and turns on the fingerprint recognition function of the determined touch drop area, thereby The number of failures of terminal fingerprint recognition is reduced, and the utility of the fingerprint recognition function of the terminal is improved.

In addition, when the terminal does not detect the holding operation, and the terminal needs to input the fingerprint, the pressure sensor senses the pressure value of the touch operation, and determines the touch landing area of the touch operation according to the pressure value, so that only the touch drop point is turned on. The fingerprint recognition function of the area enables fingerprint recognition to achieve the corresponding function when the terminal is not held, and does not cause large power consumption.

In addition, when there is a deviation between the touch drop area of the determined touch operation and the area where the actual touch operation is located, causing the fingerprint input to fail, the touch drop area may be re-determined by the pressure sensor, and the re-determined touch drop area is turned on. The fingerprint recognition function reduces the number of failures of the terminal fingerprint recognition and improves the practicality of the fingerprint recognition function of the terminal.

All the foregoing optional technical solutions may be used in any combination to form an optional embodiment of the present application, and details are not described herein again.
