The terminal related to the embodiment of the application is a touch terminal using a touch display screen. The touch display screen is a simple, convenient and natural man-machine interaction device, and has the functions of receiving touch operation of a user on the touch display screen, detecting the position of the touch operation, and displaying user interfaces of various applications installed on the terminal. This terminal can be through this fingerprint identification module collection fingerprint, discerns the fingerprint of gathering to carry out corresponding function based on this fingerprint.
Fig. 2 is a flowchart of a fingerprint identification function starting method according to an embodiment of the present application, and as shown in fig. 2, the fingerprint identification function starting method includes the following steps:
201. the terminal determines that the current terminal is in a designated state.
The designated state is a state in which fingerprint entry is required to trigger the next processing. The appointed state is a screen locking state, or an interface displayed by the current terminal is a fingerprint input interface. The fingerprint identification function starting method provided by the embodiment of the application is applied to the terminal in the screen locking state and the screen unlocking state because the terminal does not respond to the touch operation of the touch display screen when the terminal is in the shutdown state. The screen locking state refers to the state that the terminal is not unlocked. When the terminal is in a non-screen-locking state, a fingerprint input interface is required to be opened to trigger a fingerprint identification function. The fingerprint input interface is a user interface which is installed on the terminal and can complete corresponding functions only by inputting fingerprints and performing identity authentication. For example, when an application of the terminal needs fingerprint identification during payment, the terminal displays a fingerprint input interface of the application, that is, a payment interface, so as to prompt a user that a fingerprint can be input for identity authentication. And when the user inputs the fingerprint and the identity authentication is successful, the terminal executes the payment function.
When the terminal does not have fingerprint identification's needs, the terminal places the fingerprint identification module that this touch display screen below set up in the dormant state, and when this fingerprint identification module was in the dormant state, this fingerprint identification module was not carried out fingerprint collection and discernment to the touch operation of touch display screen to the user. When an application of the terminal needs to perform fingerprint identification, that is, the terminal is in an appointed state, the terminal can start a fingerprint identification function of a touch drop point area for a user to perform touch operation.
202. When the terminal detects the holding operation, the terminal determines the holding gesture of the holding operation and predicts a touch drop point area corresponding to the holding gesture.
Because the terminal supports full-screen fingerprint identification, a user can perform touch operation on any area of the touch display screen to perform fingerprint input, and when the terminal needs to perform fingerprint input, the full-screen fingerprint identification function is started, so that larger power consumption can be caused. In order to reduce power consumption, a touch landing point area of touch operation of a user on the touch display screen can be determined, so that only the fingerprint identification function of the touch landing point area is started.
In order to determine a touch landing area of a touch operation of a user on the touch display screen, a thermal sensor may be provided at an edge of the terminal, and since a body temperature of a person is different from a temperature of the terminal, whether a temperature change occurs at the edge of the terminal may be sensed by the thermal sensor, so as to detect whether a holding operation exists, and thus, different methods of determining the touch landing area may be selected according to whether the terminal is currently held.
When the terminal detects the holding operation, the position, the shape and the area of the contact area of the current hand of the user and the edge of the terminal can be detected and obtained through the thermal sensor, so that the current holding gesture of the user, such as left-hand holding, right-hand holding and two-hand holding, can be obtained through analysis. When the holding gestures of the user are different, the touch drop point areas of the touch operation performed on the touch display screen by the user may be different, so that the touch drop point areas of the touch operation performed on the touch display screen can be determined according to the holding gestures.
In practical implementation, when determining the touch landing area of the touch operation on the touch display screen according to the holding gesture, there may be, but is not limited to, the following two ways:
in the first mode, according to the holding gesture, the finger drop point range of the user is predicted, and the finger drop point range is determined as a touch drop point area.
In a possible implementation manner, according to the holding gesture, when the terminal predicts the finger drop point range of the user, according to the contact position between the hand and the terminal touch display screen and the preset finger length, a sector area with the start point of the contact position as the center of circle and the preset finger length as the radius is determined as the finger drop point range of the user. The preset finger length can be a default of the system, or can be preset by the user according to the finger length of the user. The default preset finger length of the system can be obtained according to the feedback of the general user. Of course, the angle of the sector area can be set according to the user's own usage habit.
The first method may have the following three scenarios in implementation:
when the holding gesture indicates that the current terminal is held by the left hand of the user, the area where the left hand fingers of the user possibly fall on the touch display screen can be predicted, namely the left hand finger falling point range of the user, and the left hand finger falling point range is determined as the touch falling point area; or the like, or, alternatively,
when the holding gesture indicates that the current terminal is held by the right hand of the user, the area where the fingers of the right hand of the user possibly fall on the touch display screen can be predicted, namely the falling point range of the fingers of the right hand of the user, and the falling point range of the fingers of the right hand is determined as the touch falling point area; or the like, or, alternatively,
when the holding gesture indicates that the user is held by both hands at present, the area where fingers of both hands of the user may fall on the touch display screen can be predicted, namely the finger falling point range of both hands of the user, and the finger falling point range of the left hand, or the finger falling point range of the right hand, or the finger falling point ranges of the left hand and the right hand can be determined as the touch falling point area.
When the holding gesture indicates that the current terminal is held by the two hands of the user, the dominant hand can be set according to the use habit of the user in actual implementation, and the finger drop point range of the dominant hand of the user is determined as the touch drop point area.
And in the second mode, according to the holding gesture and the touch operation record, determining an area, in the touch operation record, of which the touch operation frequency corresponding to the holding gesture is greater than a first preset threshold value, as a touch drop point area.
The terminal can record holding gestures, areas of touch operation and corresponding functions of the touch operation when a user touches the touch display screen, and touch operation records are obtained. The terminal can also perform classified statistics on the touch operation according to the recorded holding gestures to obtain the area of the touch operation corresponding to each holding gesture and the number of times of the touch operation performed in each area. The terminal can query the touch operation record corresponding to the current holding gesture in the touch operation record based on the holding gesture obtained through analysis, so that an area with the touch operation frequency larger than a first preset threshold value corresponding to the current holding gesture can be obtained, and the area is determined as a touch drop point area.
For example, when the holding gesture indicates that the terminal is currently held by the left hand of the user, the terminal may query, in the touch operation record, the touch operation record when the terminal is held by the left hand of the user, and determine, in a query result, an area where the number of touch operations is greater than a first preset threshold as the touch drop point area. When the holding gesture indicates that the current terminal is held by the right hand of the user and held by the two hands of the user, the step of querying and determining the touch drop point area by the terminal is the same as the step of holding by the left hand of the user, which is not described in detail in the embodiment of the present application.
203. And the terminal starts the fingerprint identification function of the touch drop point area.
When the terminal does not have fingerprint identification's needs, the terminal places the fingerprint identification module that this touch display screen below set up in the dormant state, and when this fingerprint identification module was in the dormant state, this fingerprint identification module was not carried out fingerprint collection and discernment to the touch operation of touch display screen to the user. When certain application of the terminal needs to perform fingerprint identification, the fingerprint identification function of a touch drop point area for touch operation of a user can be started, so that the fingerprint of the user can be conveniently collected in the touch drop point area, and the collected fingerprint is compared with the preset fingerprint in characteristic points, so that the fingerprint identification is completed. Therefore, only the fingerprint identification function of the touch drop point area of the touch operation is started, the problem of high power consumption caused by the fact that the fingerprint identification function is started in a full screen mode is effectively solved, the power consumption of the terminal is reduced, and the service life of terminal hardware is prolonged.
In practical implementation, for example, the two ways of determining the touch drop point area and the specific implementation thereof may cause the touch drop point area for starting the fingerprint identification function to have a deviation from an area where a user actually performs a touch operation on the touch display screen, and for example, when the terminal is actually used, the user may also hold the terminal by one hand and perform a touch operation on the touch display screen by a finger of the other hand, therefore, the touch landing point area for starting the fingerprint identification function has deviation from the actual touch landing point area, so that the terminal does not detect the touch operation in the touch landing point area and detects the touch operation to other areas of the touch display screen, under the circumstance, after the terminal starts the fingerprint identification function of the touch drop point area determined according to the holding gesture, the fingerprint of the user cannot be acquired and identified, and therefore the identity authentication fails.
In order to solve the problem that the identity authentication fails due to the fact that the touch drop point area with the fingerprint identification function is turned on is deviated from the actual touch drop point area, the following processing modes can be adopted: when the touch operation on the touch drop point area is not detected within the preset time and the touch operation on other areas of the touch display screen is detected, the touch drop point area of the touch operation can be determined according to the pressure value of the touch operation on the other areas, and the fingerprint identification function of the touch drop point area of the touch operation is restarted, so that the failure times of terminal fingerprint identification are reduced, and the practicability of the fingerprint identification function of the terminal is improved. In a specific implementation, the specific step of determining the touch landing point area of the touch operation according to the pressure value of the touch operation in the other area may refer to steps 205 to 208 described below.
The above steps 202 to 203 are processes in which, when the terminal detects a holding operation, the terminal determines a holding gesture of the holding operation, predicts a touch drop point region corresponding to the holding gesture, and starts a fingerprint identification function of the touch drop point region, and there may be a scenario in a specific implementation: the terminal does not detect the holding operation, and detects the touch operation on the touch display screen. In this scenario, the detailed implementation steps may refer to steps 204 to 208.
204. When the terminal does not detect the holding operation and detects the touch operation on the touch display screen, the following steps 205 to 208 are performed.
The user can place the terminal on another object (for example, a table), and perform a touch operation on the touch display screen of the terminal, at this time, that is, the terminal does not detect the holding operation, and when the touch operation on the touch display screen is detected, the terminal cannot determine the touch drop point area of the touch operation on the touch display screen according to the holding gesture of the user, and then the touch operation can be analyzed, and the touch drop point area of the touch operation is determined according to the pressure value of the touch operation, and the fingerprint identification function of the touch drop point area of the touch operation is started, so as to implement the identity authentication.
The touch display screen of the terminal can be provided with a pressure sensor below, when a user touches the touch display screen, the pressure sensor provided by the terminal can measure the pressure value of the touch operation based on deformation or displacement, and when the pressure values of the touch operation are different, the functions corresponding to the touch operation can be different. The terminal can determine the function corresponding to the touch operation based on different pressure values and respond to the touch operation to realize the corresponding function.
The specific implementation process of the terminal determining the touch drop point area of the touch operation according to the pressure value of the touch operation is as follows in steps 205 to 207, and after determining the touch drop point area of the touch operation, in step 208, the fingerprint identification function of the touch drop point area is turned on to perform identity authentication.
205. The terminal measures a pressure value of the touch operation.
The terminal measures the pressure value of the touch operation through the pressure sensor, so that the pressure value can be compared with a second preset threshold value, and whether the current touch operation is the touch operation for fingerprint identification is determined.
In a possible implementation manner, when the terminal detects a touch operation on the touch display screen, the piezoresistor in the pressure sensor equipped on the terminal may deform along with the touch operation, and the resistance value of the piezoresistor changes due to the deformation, 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, a diaphragm in a pressure sensor equipped on the terminal may be displaced along with the touch operation, and a resistance value of the diaphragm is changed due to the displacement, so that a pressure value of the current touch operation can be measured according to a current or voltage change.
The above implementation manners can all realize that the pressure value is measured by the pressure sensor for the touch operation performed by the user on the touch display screen, and certainly, other types of pressure sensors are possible in the actual implementation, which is not limited in the embodiment of the present application.
206. And when the pressure value of the touch operation is larger than a second preset threshold value, the terminal acquires the coordinate of the pressure center point of the touch operation.
The second preset threshold may be set according to a user's usage habit. The second preset threshold determines a 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 different functions.
In this embodiment of the application, the pressure value of the touch operation being greater than the second preset threshold value may be used as a determination condition for starting the fingerprint identification function when the terminal needs to perform fingerprint identification. When the terminal measures the pressure value of the touch operation, the coordinates of the pressure center point of the touch operation can be obtained, and the pressure center point can be a maximum deformation point or a maximum displacement point caused by the touch operation, or can be a pressure action point of the touch operation. Since the pressure center point is generally located at the center of the fingerprint of the user, the coordinates of the pressure center point of the touch operation can be obtained, and the touch drop point area of the touch operation can be determined based on the coordinates of the pressure center point. The terminal receives the touch operation, measures the pressure value of the touch operation and analyzes the pressure of the touch operation, and the coordinate of the pressure center point of the pressure can be obtained.
207. And the terminal determines the area with the coordinate of the pressure center point as the center and the area as the preset area as the touch drop point area.
The terminal may determine a region having the coordinate of the pressure center point as a center and the area as a preset area as the touch drop point region. After research and analysis of a user's fingerprint, the size of the resulting fingerprint is typically less than 1 square centimeter (cm)2) Thus the predetermined area may be 1cm in a specific implementation2For reference. The touch landing point area may be a circular area, and may be an area with other shapes, which is not limited in this application.
208. And the terminal starts the fingerprint identification function of the touch drop point area.
After the terminal determines the touch drop point area, the fingerprint identification function of the touch drop point area is started so as to collect the fingerprint of the user in the touch drop point area, and the collected fingerprint is compared with the preset fingerprint in characteristic points, so that the fingerprint identification is completed.
The above steps 204 to 208 are processes of sensing a pressure value of a touch operation on the touch display screen through the pressure sensor when the terminal does not detect the holding operation, and determining a touch drop point area of the touch operation according to the pressure value of the touch operation, thereby starting a fingerprint identification function of the touch drop point area.
According to the method and the device, when the terminal detects the holding operation, the touch drop point area corresponding to the holding gesture is predicted according to the holding gesture of the holding operation, so that only the fingerprint identification function of the touch drop point area is started, the problem of high power consumption caused by the fact that the fingerprint identification function is started in a full screen mode is effectively solved, the power consumption of the terminal is reduced, and the service life of terminal hardware is prolonged. Further, when the terminal does not detect the holding operation and the fingerprint needs to be input into the terminal, the pressure value of the touch operation is sensed through the pressure sensor, and the touch falling point area of the touch operation is determined according to the pressure value, so that only the fingerprint identification function of the touch falling point area is started, the terminal can also perform fingerprint identification to realize the corresponding function when not being held, and large power consumption can not be caused. Furthermore, when the determined touch drop point area of the touch operation and the area where the actual touch operation is located have deviation, and the fingerprint input fails, the touch drop point area can be re-determined through the pressure sensor, and the fingerprint identification function of the re-determined touch drop point area is started, so that the failure times of terminal fingerprint identification are reduced, and the practicability of the fingerprint identification function of the terminal is improved.

The touch display screen 530 is generally disposed on a front panel of the terminal 530. The touch display screen 530 may be designed as a full-screen, a curved screen, or a profiled screen. The touch display screen 530 may also be designed as a combination of a full-screen and a curved screen, and a combination of a non-flat screen and a curved screen, which is not limited in this embodiment. Wherein:
full screen
A full screen may refer to a screen design where the touch display screen 530 occupies more than a threshold (e.g., 80% or 90% or 95%) of the screen of the front panel of the terminal 500. One way of calculating the screen occupation ratio is as follows: (area of touch display 530/area of front panel of terminal 500) × 100%; another way to calculate the screen ratio is: (area of actual display area in touch display 530/area of front panel of terminal 500) × 100%; another calculation method of the screen occupation ratio is as follows: (diagonal of touch display screen 530/diagonal on front panel of terminal 500) × 100%. In the illustrative example shown in fig. 7A, almost all areas on the front panel of the terminal 500 are the touch display screen 530, and all areas on the front panel 40 of the terminal 500 except for the edge generated by the center frame 41 are the touch display screen 530.
