Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary only for the purpose of explaining the embodiments of the present application, and are not to be construed as limiting the embodiments of the present application.
Referring to fig. 1, the present application provides a method for enabling a shortcut function of an electronic device 100. The electronic device 100 is pre-stored with a plurality of fingerprint templates, which form at least one fingerprint combination. Each fingerprint combination corresponds to a shortcut function. The method for starting the shortcut function comprises the following steps:
011: acquiring first fingerprint data of at least two fingers of the same user;
012: finding a first fingerprint template matching each first fingerprint data among the plurality of fingerprint templates;
013: determining a current fingerprint combination according to a plurality of first fingerprint templates; and
014: and starting the current shortcut function corresponding to the current fingerprint combination.
Referring to fig. 2, the present application further provides an electronic device 100. The method for enabling the shortcut function of the present application may be implemented by the electronic device 100 of the present application. The electronic device 100 includes a fingerprint identification module 10 and a processor 20. Step 011 can be implemented by the fingerprint identification module 10. Step 012, step 013 and step 014 may be implemented by processor 20. That is, the fingerprint identification module 10 may be used to obtain the first fingerprint data of at least two fingers of the same user. The processor 20 may be configured to find a first fingerprint template matching each of the first fingerprint data among the plurality of fingerprint templates, determine a current fingerprint combination from the plurality of first fingerprint templates, and enable a current shortcut function corresponding to the current fingerprint combination.
The shortcut function may include copy, cut, paste, select, delete, close, cancel, web search, translate, save, replace, create, etc. Electronic device 100 may be a mobile phone, a tablet computer, a notebook computer, an intelligent wearable device (such as an intelligent bracelet, an intelligent watch, an intelligent glasses, an intelligent helmet, etc.), an intelligent furniture, a virtual reality device, etc. The electronic device 100 is described as a mobile phone in the present application, but the form of the electronic device 100 is not limited to the mobile phone. Fingerprint identification module 10 can be capacitanc fingerprint module, optics fingerprint module, supersound fingerprint module etc. The electronic device 100 further includes a display screen 30 (integrated with display and touch functions), and the fingerprint identification module 10 is disposed under the display screen 30. When fingerprint identification module 10 was placed under display screen 30, fingerprint identification module 10 corresponded the fingerprint identification region on display screen 30 and contained in the display area of display screen 30, and the ratio of the regional area of fingerprint identification and the area of display area is greater than the predetermined ratio to make fingerprint identification module 10 can acquire the fingerprint data of a plurality of fingers simultaneously. The fingerprint identification area may correspond to a part of the display area (i.e., an area fingerprint) or may correspond to the whole display area (i.e., a full screen fingerprint).
It can be appreciated that when a user enables a shortcut function on the electronic device 100, the process of enabling the shortcut function is generally cumbersome. Taking the withdrawal message as an example, the user needs to press the display screen 30 for a long time, and after the display screen 30 senses the long-press operation of the user, the option of the withdrawal message is displayed for the user to select. The message can be withdrawn only after the user clicks the withdrawal option. The process of enabling the shortcut function of withdrawing messages is cumbersome, long in duration and poor in user experience.
In the method for starting the shortcut function of the present application, the electronic device 100 pre-stores a plurality of fingerprint templates, the plurality of fingerprint templates form at least one fingerprint combination, and each fingerprint combination corresponds to one shortcut function. The templates of each fingerprint combination are fingerprint templates of different fingers respectively. Specifically, at least two fingerprint templates of the plurality of fingerprint templates form at least one fingerprint combination, and each fingerprint combination corresponds to one shortcut function. For example, the number of the fingerprint templates is two, the two fingerprint templates are respectively the fingerprint template of the left index finger and the fingerprint template of the left middle finger, the two fingerprint templates only form a fingerprint combination, and the fingerprint combination correspondingly replicates the shortcut function. For another example, the number of the fingerprint templates is four, the four fingerprint templates are respectively a fingerprint template of a left index finger, a fingerprint template of a left middle finger, a fingerprint template of a left ring finger and a fingerprint template of a left little finger, the fingerprint template of the left index finger and the fingerprint template of the left middle finger form a fingerprint combination, and the fingerprint combination correspondingly replicates the shortcut function; the fingerprint template of the index finger of the left hand, the fingerprint template of the middle finger of the left hand and the fingerprint template of the ring finger of the left hand form a fingerprint combination, and the fingerprint combination is correspondingly pasted with the shortcut function; the fingerprint template of the left index finger, the fingerprint template of the left middle finger, the fingerprint template of the left ring finger and the fingerprint template of the left little finger form a fingerprint combination, and the fingerprint combination corresponds to the shortcut function of cutting, and the like. The above description of forming a plurality of fingerprint combinations for a plurality of fingerprint templates and corresponding the plurality of fingerprint combinations to different shortcut functions respectively is only an example, the combination form of the plurality of fingerprint templates is not limited thereto, and the corresponding relationship between the fingerprint combinations and the shortcut functions is not limited thereto. The user can customize the corresponding relationship among the fingerprint template, the fingerprint combination and the shortcut function through the electronic device 100, and the corresponding relationship among the fingerprint template, the fingerprint combination and the shortcut function can be stored in the electronic device 100 in the form of a mapping table.
The user may enable the shortcut function by entering fingerprints of at least two fingers in the electronic device 100, wherein the shortcut function to be currently enabled by the user is simply referred to as a current shortcut function. Specifically, the user touches the display screen 30 of the electronic device 100 with at least two fingers. The fingerprint identification module 10 located below the display screen 30 acquires first fingerprint data of at least two fingers of the same user (when the first fingerprint data is to enable the current shortcut function for the electronic device 100, the fingerprint data of the user finger acquired by the fingerprint identification module 10). Fingerprint identification module 10 acquires the first fingerprint data of two at least fingers of same user, sends these first fingerprint data to processor 20. The processor 20 matches each first fingerprint data with each fingerprint template stored in the electronic device 100. If the processor 20 finds a first fingerprint template matching each first fingerprint data among the plurality of fingerprint templates, the processor 20 finds a current fingerprint combination corresponding to the determined plurality of first fingerprint templates in the mapping table. If there are current fingerprint combinations corresponding to the plurality of first fingerprint templates in the mapping table, the processor 20 further finds a current shortcut function corresponding to the current fingerprint combination in the mapping table and enables the current shortcut function.
It should be noted that, when the user enters the fingerprints of at least two fingers into the electronic device 100 to enable the current shortcut function, the at least two fingers of the user may be simultaneously placed on the display screen 30 or time-divisionally placed on the display screen 30. When at least two fingers of the user are placed on the display screen 30 in time, the remaining fingers that have been placed on the display screen 30 can leave the display screen 30 if and only if the last finger that has not been placed on the display screen 30 is placed on the display screen 30 for a predetermined time, and the time difference between the time the first finger is placed on the display screen 30 and the time the last finger is placed on the display screen 30 should be less than or equal to the predetermined time difference. It can be understood that if a situation occurs in which the fingers are not all placed on the display screen 30, for example, the user originally intends to enable the current shortcut function of pasting through the left index finger, the left middle finger and the left ring finger, but the user places the left index finger and the left middle finger on the display screen 30 first, then places the left ring finger on the display screen 30, and when the user places the left ring finger on the display screen 30, the left index finger and the left middle finger have left the display screen 30, the fingerprint identification module 10 simultaneously obtains the first fingerprint data of the left index finger and the left middle finger, and the processor 20 may enable the current shortcut function of copying directly according to the first fingerprint data of the left index finger and the left middle finger, which results in the processor 20 enabling the wrong shortcut function. Similarly, if the time difference between the time when the first finger is placed on the display screen 30 and the time when the last finger is placed on the display screen 30 is greater than the predetermined time difference, at this time, the fingerprint identification module 10 will send the pre-acquired part of the first fingerprint data (excluding the first fingerprint data of the last finger) to the processor 20, and the processor 20 will enable the current shortcut function directly according to the pre-acquired part of the first fingerprint data, so that the current shortcut function enabled by the processor 20 is not consistent with the current shortcut function that the user actually needs to enable. After the last finger not placed on the display screen 30 is set to be placed on the display screen 30 for the preset time, the rest of the fingers placed on the display screen 30 can leave the display screen 30, and the time difference between the time when the first finger is placed on the display screen 30 and the time when the last finger is placed on the display screen 30 is smaller than or equal to the preset time difference, so that the fingerprint identification module 10 can be ensured to simultaneously acquire the first fingerprint data of the fingers originally intended by a plurality of users, and the accurate starting of the current shortcut function can be performed according to the plurality of first fingerprint data.
In addition, at least two fingers of the same user include: (1) at least two fingers on the right hand of the same user, such as the right index finger and the right middle finger, etc.; (2) at least two fingers on the left hand of the same user, e.g., the left index finger and the left middle finger, etc.; (3) at least two fingers on the right and left hand of the same user, e.g., right index finger and left middle finger, etc.
According to the method for starting the shortcut function and the electronic device 100, the fingerprint templates of the fingers are bound with the shortcut function, the user can start the shortcut function by inputting the first fingerprint data of the fingers into the electronic device 100, the starting process of the shortcut function is simple, the duration is short, and the user experience is good.
Referring to fig. 3, in some embodiments, before step 011, the enabling method further includes:
021: selecting a shortcut function as a shortcut function to be bound;
022: acquiring second fingerprint data of at least two fingers of the same user;
023: judging whether a second fingerprint template matched with each second fingerprint data exists in the plurality of fingerprint templates;
024: if yes, forming a plurality of second fingerprint templates matched with the second fingerprint data into a fingerprint combination to be bound; and
025: and binding the fingerprint combination to be bound with the shortcut function to be bound.
Prior to step 025, the enabling method further comprises:
026: judging whether the fingerprint combination to be bound is bound with other shortcut functions except the shortcut function to be bound;
if not, the step of binding the fingerprint combination to be bound with the shortcut function to be bound is carried out;
and if so, re-executing the step of acquiring the second fingerprint data of at least two fingers of the same user.
Referring to fig. 2, in some embodiments, step 021, step 023, step 024, step 025 and step 026 may all be implemented by processor 20. Step 022 may be implemented by the fingerprint identification module 10. That is, the processor 20 may be configured to select a shortcut function as the shortcut function to be bound. The fingerprint identification module 10 can be used to obtain second fingerprint data of at least two fingers of the same user. The processor 20 is further configured to determine whether a second fingerprint template matching each second fingerprint data exists in the plurality of fingerprint templates, form the plurality of second fingerprint templates matching the second fingerprint data into one to-be-bound fingerprint combination when the second fingerprint template exists, and bind the to-be-bound fingerprint combination with the to-be-bound shortcut function. The processor 20 may also be configured to determine whether the combination of fingerprints to be bound is already bound to another shortcut function other than the shortcut function to be bound. If the combination to be bound is not bound with other shortcut functions except the shortcut function to be bound, the processor 20 binds the fingerprint combination to be bound with the shortcut function to be bound. If the combination to be bound is already bound with other shortcut functions except the shortcut function to be bound, the fingerprint identification module 10 re-acquires second fingerprint data of at least two fingers of the same user, which are different from the previous finger.
Referring to fig. 4, if the user wants to activate the current shortcut function by the electronic device 100 executing the operations of steps 011 to 014, the user firstly uses the electronic device 100 to bind the fingerprint combination with the shortcut function. Specifically, the electronic device 100 has pre-stored fingerprint templates of a plurality of fingers, where the plurality of fingerprint templates are pre-entered by a user on the electronic device 100, and generally, the user corresponding to the plurality of fingerprint templates is the owner of the electronic device 100. In the interface for binding the fingerprint combination and the shortcut function, a plurality of shortcut functions for the user to select, such as displaying the shortcut functions of copying, pasting, full selecting, deleting, closing, and canceling, are displayed on the display screen 30. After the user touches the display screen 30, the processor 20 determines the shortcut function selected by the user according to the position where the user touches the display screen 30, and takes the shortcut function selected by the user as the shortcut function to be bound. Assuming that the to-be-bound shortcut function is a copy, the electronic device 100 prompts the user to place a plurality of fingers in the fingerprint identification area, for example, displaying "please place at least two fingers of your on the fingerprint identification area on the display screen 30: such as the left index finger + the left middle finger, to prompt the user to place a plurality of fingers in the fingerprint identification area, although the prompting manner is not limited thereto, for example, the electronic device 100 may prompt the user by voice, and so on. Subsequently, the fingerprint identification module 10 acquires the second fingerprint data of at least two fingers of the user (when the second fingerprint data is the corresponding relation between the user defined shortcut function and the fingerprint combination through the electronic device 100, the fingerprint data of the user finger acquired by the fingerprint identification module 10). Subsequently, the fingerprint identification module 10 sends the plurality of second fingerprint data to the processor 20, and the processor 20 searches the plurality of fingerprint templates for a second fingerprint template matching with each second fingerprint data. If there is a second fingerprint template matching each second fingerprint data among the plurality of fingerprint templates, the processor 20 forms the plurality of second fingerprint templates matching the second fingerprint data into one combination of fingerprints to be bound. If any second fingerprint template cannot be found in the plurality of fingerprint templates, the electronic device 100 may display a word "please confirm whether the used finger is the finger that has entered the fingerprint template" to prompt the user to use the finger that has entered the fingerprint template to form a fingerprint combination, further, as shown in fig. 4, the electronic device 100 may further adjust the brightness of a predetermined area of the display screen 30 to more intuitively prompt the user which second fingerprint data is unqualified, where the qualified second fingerprint data is the fingerprint data that can find the second fingerprint template that matches the qualified second fingerprint data, and the predetermined area is the position where the finger corresponding to the second fingerprint data that cannot find the matched second fingerprint template touches the display screen 30. After the processor 20 obtains the plurality of qualified second fingerprint data, the processor 20 forms a plurality of second fingerprint templates corresponding to the plurality of second fingerprint data into a to-be-bound fingerprint combination. Subsequently, the processor 20 determines whether the combination to be bound has been bound with another shortcut function other than the shortcut function to be bound, and if the fingerprint combination to be bound has been bound with another shortcut function, for example, the fingerprint combination to be bound has been bound with a revocation, the processor 20 controls the display screen 30 to display a word "the fingerprint combination has been bound with a 'revocation' shortcut function, please reselect a finger" to prompt the user to use another fingerprint combination to bind the shortcut function; if the combination of the fingerprints to be bound is not bound with other shortcut functions, the processor 20 determines that there is no combination conflict, the processor 20 binds the combination of the fingerprints to be bound with the shortcut functions to be bound, and controls the display screen 30 to display a word of "binding successfully" to prompt the user to finish the customization of copying the corresponding relationship between the shortcut function and the combination of the fingerprints.
In the starting method, the user-defined process of the corresponding relation between the shortcut function and the fingerprint combination is simple to operate, and the user experience is good. Moreover, since the processor 20 determines whether each second fingerprint data is qualified fingerprint data, it can be ensured that only the owner can set the corresponding relationship between the shortcut function and the fingerprint combination, and the owner cannot set the corresponding shortcut function by using the fingerprint combination because the owner does not use the electronic device 100 to set the corresponding relationship between the fingerprint combination and the shortcut function.
In some embodiments, a shortcut function corresponds to only one fingerprint combination. In other embodiments, a shortcut function may also correspond to a plurality of fingerprint combinations, for example, a fingerprint combination of left index finger + left middle finger corresponds to a copy of the shortcut function, and a fingerprint combination of right index finger + right middle finger also corresponds to a copy of the shortcut function. One shortcut function corresponds to a plurality of fingerprint combination setting modes, so that the single-hand operation of a user can be facilitated.
Referring to fig. 5, in some embodiments, each of the first fingerprint data includes a fingerprint image and a first touch pressure, each of the first fingerprint data corresponds to a fingerprint template, each of the fingerprint templates includes an image template and a predetermined touch pressure, and the predetermined touch pressures of the fingerprint templates are the same. Step 012 includes:
01211: calculating the current matching degree between each fingerprint image and each image template;
01212: judging whether a current matching degree with a value larger than the first matching degree exists in the plurality of current matching degrees;
01213: if the fingerprint matching degree exists, taking the fingerprint template corresponding to the current matching degree with the value larger than the first matching degree as a first fingerprint template matched with the first fingerprint data;
01214: if not, calculating a first difference value between each first touch pressure and a preset touch pressure;
01215: adjusting the first matching degree to a second matching degree according to the first difference, wherein the first matching degree is greater than the second matching degree; and
01216: and taking the fingerprint template corresponding to the current matching degree with the value larger than the second matching degree as the first fingerprint template matched with the first fingerprint data.
Referring back to FIG. 2, in certain embodiments, steps 01211, 01212, 01213, 01214, 01215, and 01216 may all be implemented by processor 20. That is, the processor 20 is further configured to calculate a current matching degree between each fingerprint image and each image template and determine whether there is a current matching degree having a value greater than the first matching degree among the plurality of current matching degrees. If the fingerprint matching degree exists, the processor 20 takes the fingerprint template corresponding to the current matching degree with the value larger than the first matching degree as a first fingerprint template matched with the first fingerprint data; if not, the processor 20 calculates a first difference between each first touch pressure and a predetermined touch pressure, adjusts the first matching degree to a second matching degree according to the first difference, and takes the fingerprint template corresponding to the current matching degree with a value greater than the second matching degree as the first fingerprint template matched with the first fingerprint data, wherein the first matching degree is greater than the second matching degree.
In particular, when the processor 20 acquires the first fingerprint data, the first fingerprint data needs to be matched with the fingerprint template. The first fingerprint data include two data, namely a fingerprint image and a first touch pressure, when the fingerprint image enables a shortcut function through the electronic device 100 for a user, the fingerprint identification module 10 acquires an image of a finger of the user, and the first touch pressure refers to a pressure of the finger touching the display screen 30 when the user enables the shortcut function through the electronic device 100. The fingerprint template includes image template and predetermined touch pressure, the fingerprint image that fingerprint identification module 10 obtained when the image template is the user through the user-defined fingerprint combination of electronic equipment 100 and shortcut function's corresponding relation, when predetermined touch pressure user passes through the user-defined fingerprint combination of electronic equipment 100 and shortcut function's corresponding relation, the pressure of user's finger touch display screen 30, predetermined touch pressure is that electronic equipment 100 presets, in the self-defined in-process of fingerprint combination and shortcut function's corresponding relation, electronic equipment 100 can indicate the user to touch display screen 30 with predetermined touch pressure.
Assume that there are two first fingerprint data, F1、F2First fingerprint data F1The fingerprint image in (1) is FI1The first stepA touch pressure of FN1First fingerprint data F2The fingerprint image in (1) is FI2The first touch pressure is FN2(ii) a Three fingerprint templates are respectively T1、T2、T3Fingerprint template T1The image template in (1) is TI1Predetermined touch pressure of TN0Fingerprint template T2The image template in (1) is TI2Predetermined touch pressure of TN0Fingerprint template T3The image template in (1) is TI3Predetermined touch pressure of TN0. The processor 20 first calculates F separatelyI1And TI1、TI2、TI3Current degree of match M between11、M12、M13And separately calculate FI2And TI1、TI2、TI3Current degree of match M between21、M22、M23. The processor 20 determines whether there is a current matching degree having a value greater than the first matching degree among a plurality of current matching degrees calculated from the same fingerprint image, i.e., determines M11、M12、M13Whether there is a current matching degree having a value greater than the first matching degree, and determining M21、M22、M23If there is a current degree of match with a value greater than the first degree of match.

It can be understood that when the finger of the user touches the display screen 30 with different pressures, the fingerprint images acquired by the fingerprint identification module 10 will be different. For example, when the pressure of the user touching the display screen 30 is large, the fingerprint identification module 10 obtains more information of the fingerprint image, and the integrity of the fingerprint image is high; and when the pressure that the user touched display screen 30 was less, the information of the fingerprint image that fingerprint identification module 10 obtained was less, and fingerprint image integrity is lower. Since the pressure at which the user touches the display screen 30 (i.e., the first touch pressure) may be different from the predetermined touch pressure during the process of the user activating the current shortcut function, the current matching degree between the fingerprint image and the accurate image template may not be high. At this time, if a higher matching degree (i.e., a first matching degree) is set, it may be that an image template matching the fingerprint image cannot be found, and further, the current shortcut function cannot be successfully enabled; and the matching degree is reduced according to the first difference between the first touch pressure and the preset touch pressure, namely the first matching degree is adjusted to be the second matching degree, so that the successful matching between the fingerprint image and the accurate image template can be ensured, and the probability that the current shortcut function is successfully started is improved.
Referring to fig. 6, in some embodiments, before step 011, the enabling method further includes:
031: selecting a shortcut function as a shortcut function to be bound;
032: when the fingers of the user touch the display screen 30, acquiring a second touch pressure of each finger touching the display screen 30;
033: calculating a second difference between the second touch pressure and the predetermined touch pressure;
034: prompting the user to adjust the second touch pressure when the second difference is greater than the predetermined difference to change the second difference such that the second difference is less than the predetermined difference;
035: acquiring a fingerprint image of each finger when the second difference is smaller than a predetermined difference;
036: taking the fingerprint image of each finger as an image template, and packaging each image template and preset touch pressure into a second fingerprint template;
037: forming a plurality of second fingerprint templates into a fingerprint combination to be bound; and
038: and binding the fingerprint combination to be bound with the shortcut function to be bound.
Referring back to fig. 2, in some embodiments, step 031, step 033, step 034, step 036, step 037 and step 038 may be implemented by the processor 20. Step 032 may be implemented by display 30. Step 035 can be implemented by the fingerprint recognition module 10. That is, the processor 20 may be further configured to select a shortcut function as the shortcut function to be bound. The display screen 30 may be used to acquire a second touch pressure of each finger touching the display screen 30 when the user's finger touches the display screen 30. The processor 20 may be further configured to calculate a second difference between the second touch pressure and the predetermined touch pressure, and prompt the user to adjust the second touch pressure to change the second difference when the second difference is greater than the predetermined difference such that the second difference is less than the predetermined difference. The fingerprint identification module 10 may be further configured to obtain a fingerprint image of each finger when the second difference is less than the predetermined difference. The processor 20 is further configured to take the fingerprint image of each finger as an image template, form a plurality of second fingerprint templates into a fingerprint combination to be bound, and bind the fingerprint combination to be bound with the shortcut function to be bound, wherein each image template is encapsulated with a predetermined touch pressure into one second fingerprint template.
When the fingerprint combination is bound to the shortcut function, the electronic apparatus 100 needs to acquire a fingerprint image of a user's finger when the user touches the display screen 30 at a predetermined touch pressure. Specifically, in the interface for binding the fingerprint combination and the shortcut function, a plurality of shortcut functions available for the user to select, such as displaying the shortcut functions of copying, pasting, full selecting, deleting, closing, and canceling, are displayed on the display screen 30. After the user touches the display screen 30, the processor 20 determines the shortcut function selected by the user according to the position where the user touches the display screen 30, and takes the shortcut function selected by the user as the shortcut function to be bound. Assuming that the to-be-bound shortcut function is a copy, the electronic device 100 prompts the user to place a plurality of fingers in the fingerprint identification area, for example, displaying "please place at least two fingers of your on the fingerprint identification area on the display screen 30: such as the left index finger + the left middle finger, to prompt the user to place multiple fingers within the fingerprint identification area. Subsequently, the display screen 30 obtains a second touch pressure of each finger of the user, where the second touch pressure is a pressure of the user touching the display screen 30 without being prompted by the electronic device 100 in the process of defining the corresponding relationship between the fingerprint combination and the shortcut function. The processor 20 calculates a second difference between the second touch pressure of each finger and the predetermined touch pressure, and if the second difference is greater than the predetermined difference, the processor 20 controls the display 30 to prompt the user to adjust the second touch pressure, for example, as shown in fig. 7, the processor 20 adjusts the brightness of the display 30 at the position where the finger corresponding to the second difference is greater than the predetermined difference, and displays the word "please increase (or decrease) the touch pressure" to prompt the user, and so on, so that the second difference between the adjusted second touch pressure and the predetermined touch pressure is less than or equal to the predetermined difference. When the second difference is less than or equal to the predetermined difference, the fingerprint recognition module 10 obtains the fingerprint image of each finger, and sends the fingerprint image of each finger to the processor 20. The processor 20 takes the fingerprint image of each finger as an image template and encapsulates each image template with a predetermined touch pressure as a second fingerprint template. Subsequently, the processor 20 forms a plurality of second fingerprint templates into a fingerprint combination to be bound, and binds the fingerprint combination to be bound with the shortcut function to be bound.
Further, for the embodiment shown in steps 031 through 038, before step 031, the enabling method further includes: the identity of the user is identified and step 031 is only performed if the identity of the user is the owner. The identification of the user may be implemented by fingerprint identification, face identification, iris identification, voiceprint identification, digital password, pattern password, and the like, which is not limited herein. In the embodiment shown in steps 031-038, the processor 20 does not determine whether the second fingerprint data is fingerprint data of the owner, so that, in order to ensure that only the owner can set the corresponding relationship between the shortcut function and the fingerprint combination, the processor 20 needs to identify the identity of the user first, and then displays an interface defining the corresponding relationship between the shortcut function and the fingerprint combination when the identity of the user is the owner.
Referring to fig. 8, in some embodiments, each of the first fingerprint data includes a fingerprint image and a first touch pressure, each of the first fingerprint data corresponds to a fingerprint template, and each of the fingerprint templates includes an image template and a second touch pressure. Step 012 includes:
01221: calculating the current matching degree between each fingerprint image and each image template;
01222: judging whether a current matching degree with a value larger than the first matching degree exists in the plurality of current matching degrees;
01223: if the fingerprint matching degree exists, taking the fingerprint template corresponding to the current matching degree with the value larger than the first matching degree as a first fingerprint template matched with the first fingerprint data;
01224: if not, calculating a third difference value between each first touch pressure and each second touch pressure;
01225: adjusting the first matching degree to a third matching degree according to the third difference, wherein the first matching degree is greater than the third matching degree, and each fingerprint template corresponds to one third matching degree; and
01226: and taking the fingerprint template corresponding to the current matching degree with the value larger than the third matching degree as the first fingerprint template matched with the first fingerprint data.
Referring back to fig. 2, steps 01221, 01222, 01223, 01224, 01225, and 01226 may be implemented by the processor 20. That is, the processor 20 is further configured to calculate a current matching degree between each fingerprint image and each image template, and determine whether there is a current matching degree having a value greater than the first matching degree among the plurality of current matching degrees. If the fingerprint matching degree exists, the processor 20 takes the fingerprint template corresponding to the current matching degree with the value larger than the first matching degree as a first fingerprint template matched with the first fingerprint data; if not, the processor 20 calculates a third difference between each first touch pressure and each second touch pressure, adjusts the first matching degree to a third matching degree according to the third difference, and takes the fingerprint template corresponding to the current matching degree with a value greater than the third matching degree as the first fingerprint template matched with the first fingerprint data, wherein the first matching degree is greater than the third matching degree, and each fingerprint template corresponds to one third matching degree.
In particular, when the processor 20 acquires the first fingerprint data, the first fingerprint data needs to be matched with the fingerprint template. The first fingerprint data include two data, namely a fingerprint image and a first touch pressure, when the fingerprint image enables a shortcut function through the electronic device 100 for a user, the fingerprint identification module 10 acquires an image of a finger of the user, and the first touch pressure refers to a pressure of the finger touching the display screen 30 when the user enables the shortcut function through the electronic device 100. The fingerprint template includes image template and second touch pressure, and the fingerprint image that fingerprint identification module 10 obtained when the image template is the user through the user-defined fingerprint combination of electronic equipment 100 and swift function's corresponding relation, and the second touch pressure is when the user passes through the user-defined fingerprint combination of electronic equipment 100 and swift function's corresponding relation, and the user is in the pressure that does not touch display screen 30 with the finger under the condition of electronic equipment 100 suggestion.
Assume that there are two first fingerprint data, F1、F2First fingerprint data F1The fingerprint image in (1) is FI1The first touch pressure is FN1First fingerprint data F2The fingerprint image in (1) is FI2The first touch pressure is FN2(ii) a Three fingerprint templates are respectively T1、T2、T3Fingerprint template T1The image template in (1) is TI1The second touch pressure is TN1Fingerprint template T2The image template in (1) is TI2The second touch pressure is TN2Fingerprint template T3The image template in (1) is TI3The second touch pressure is TN3. The processor 20 first calculates F separatelyI1And TI1、TI2、TI3Current degree of match M between11、M12、M13And separately calculate FI2And TI1、TI2、TI3Current degree of match M between21、M22、M23. The processor 20 determines whether there is a current matching degree having a value greater than the first matching degree among a plurality of current matching degrees calculated from the same fingerprint image, i.e., determines M11、M12、M13Whether there is a current matching degree having a value greater than the first matching degree, and determining M21、M22、M23If there is a current degree of match with a value greater than the first degree of match. If M is11、M12、M13There is a current degree of matching with a value greater than the first degree of matching, assumed to be M11And M is21、M22、M23There is a current degree of matching, assumed to be M, with a value greater than the first degree of matching22Then processor 20 considers M11Corresponding fingerprint template T1I.e. with the first fingerprint data F1Matching first fingerprint template, M22Corresponding fingerprint template T2I.e. with the first fingerprint data F2A matching first fingerprint template. If M is11、M12、M13Middle absent value is largeThe processor 20 calculates the first touch pressures F respectively according to the current matching degree of the first matching degreeN1And a second touch pressure TN1A third difference N therebetween11First touch pressure FN1And a second touch pressure TN2A third difference N therebetween12And a first touch pressure FN1And a second touch pressure TN3A third difference N therebetween13. Subsequently, the processor 20 is configured to determine a third difference N11Calculating a third matching degree of the corresponding fingerprint template T1 according to the first matching degree, and calculating a third difference value N according to the third matching degree12Calculating a third matching degree of the corresponding fingerprint template T2 according to the first matching degree, and calculating a third difference N according to the third matching degree13And calculating a third matching degree of the corresponding fingerprint template T3 according to the first matching degree, wherein the third matching degree corresponding to each fingerprint template is smaller than the first matching degree. Processor 20 then determines FI1And TI1Current degree of match M between11If the current matching degree is greater than the third matching degree of the corresponding fingerprint template T1, if so, the processor 20 will determine the current matching degree M11Corresponding fingerprint template T1As first fingerprint data F1A matched first fingerprint template; if not, processor 20 determines FI1And TI2Current degree of match M between12If the current matching degree is greater than the third matching degree of the corresponding fingerprint template T2, if so, the processor 20 will determine the current matching degree M12Corresponding fingerprint template T2As first fingerprint data F2A matched first fingerprint template; if not, processor 20 continues to determine FI1And TI3Current degree of match M between13If the current matching degree is greater than the third matching degree of the corresponding fingerprint template T3, if so, the processor 20 will determine the current matching degree M13Corresponding fingerprint template T3As first fingerprint data F1A matching first fingerprint template, and if not, the processor 20 recognizes the first fingerprint data F1The first fingerprint template matched with the plurality of fingerprint templates cannot be found, and the current shortcut function fails to be started. Finding and first fingerprint data F2Matching first fingerprint template with search and first fingerprint data F1Matched first fingerprint moduleThe plates are in the same manner and will not be described further herein.
It can be understood that when the pressure of the user touching the display screen 30 is different, the fingerprint images acquired by the fingerprint identification module 10 are also different. Because in the process that the user starts the current shortcut function, the pressure (i.e., the first touch pressure) when the user touches the display screen 30 may be different from the pressure (i.e., the second touch pressure) when the user customizes the correspondence between the shortcut function and the fingerprint module, the current matching degree between the fingerprint image and the accurate image template may not be very high. At this time, if a higher matching degree (i.e., a first matching degree) is set, it may be that an image template matching the fingerprint image cannot be found, and further, the current shortcut function cannot be successfully enabled; and the matching degree is reduced according to a third difference value between the first touch pressure and the second touch pressure, namely the first matching degree is adjusted to be the third matching degree, so that the successful matching between the fingerprint image and the accurate image template can be ensured, and the probability that the current shortcut function is successfully started is improved.
Referring to fig. 9, in some embodiments, before step 011, the enabling method further includes:
041: selecting a shortcut function as a shortcut function to be bound;
042: when the fingers of the user touch the display screen 30, acquiring a second touch pressure of each finger touching the display screen 30 and a fingerprint image of each finger;
043: taking the fingerprint image of each finger as an image template, and packaging the image template of each finger and the second touch pressure of the finger into a third fingerprint template;
044: forming a plurality of third fingerprint templates into a fingerprint combination to be bound; and
045: and binding the fingerprint combination to be bound with the shortcut function to be bound.
Referring back to fig. 2, in some embodiments, step 041, step 043, step 044 and step 045 may be implemented by processor 20. Step 042 may be implemented by the display screen 30 and the fingerprint recognition module 10 together. That is, the processor 20 may be configured to select a shortcut function as the shortcut function to be bound. When user's finger touched display screen 30, display screen 30 can be used to acquire the second touch pressure of every finger touch display screen 30, and fingerprint identification module 10 can be used to acquire the fingerprint image of every finger. The processor 20 is further configured to use the fingerprint image of each finger as an image template, package the image template of each finger and the second touch pressure of the finger into a third fingerprint template, form a plurality of third fingerprint templates into a to-be-bound fingerprint combination, and bind the to-be-bound fingerprint combination with the to-be-bound shortcut function.
When the fingerprint combination is bound to the shortcut function, the electronic device 100 needs to acquire a second touch pressure of the finger touching the display screen 30 and a fingerprint image of the finger when the user touches the display screen 30. Specifically, in the interface for binding the fingerprint combination and the shortcut function, a plurality of shortcut functions available for the user to select, such as displaying the shortcut functions of copying, pasting, full selecting, deleting, closing, and canceling, are displayed on the display screen 30. After the user touches the display screen 30, the processor 20 determines the shortcut function selected by the user according to the position where the user touches the display screen 30, and takes the shortcut function selected by the user as the shortcut function to be bound. Assuming that the to-be-bound shortcut function is a copy, the electronic device 100 prompts the user to place a plurality of fingers in the fingerprint identification area, for example, displaying "please place at least two fingers of your on the fingerprint identification area on the display screen 30: such as the left index finger + the left middle finger, to prompt the user to place multiple fingers within the fingerprint identification area. Subsequently, display screen 30 acquires the second touch pressure of each finger of user, and fingerprint identification module 10 acquires the fingerprint image of each finger, and wherein, the second touch pressure is in the corresponding relation process of self-defined fingerprint combination and swift function, and the user is at the pressure that the user touched display screen 30 with the finger under the situation that does not have the suggestion of electronic equipment 100. The fingerprint identification module 10 sends the fingerprint image of each finger to the processor 20. The processor 20 takes the fingerprint image of each finger as an image template and encapsulates the image template of each finger with the second touch pressure of the finger as a third fingerprint template. Subsequently, the processor 20 forms a plurality of third fingerprint templates into one to-be-bound fingerprint combination, and binds the to-be-bound fingerprint combination with the to-be-bound shortcut function.
Further, for the embodiment shown in step 041 to step 045, before step 041, the enabling method further includes: the identity of the user is identified and step 041 is only executed if the identity of the user is the owner. The identification of the user may be implemented by fingerprint identification, face identification, iris identification, voiceprint identification, digital password, pattern password, and the like, which is not limited herein. In the embodiment shown in steps 041 to 045, the processor 20 does not determine whether the acquired fingerprints are all fingerprints of the owner, so that, to ensure that only the owner can set the corresponding relationship between the shortcut function and the fingerprint combination, the processor 20 needs to identify the identity of the user first, and then displays an interface defining the corresponding relationship between the shortcut function and the fingerprint combination when the identity of the user is the owner.
Referring to fig. 10, in some embodiments, each of the first fingerprint data includes a fingerprint image and a first touch pressure, each of the first fingerprint data corresponds to a plurality of fingerprint templates, each of the fingerprint templates includes an image template and a second touch pressure, and the second touch pressures of the plurality of fingerprint templates corresponding to each of the first fingerprint data are different. Step 012 includes:
01231: respectively calculating a fourth difference value between each first touch pressure and each second touch pressure in each finger, and taking the fingerprint template corresponding to the fourth difference value with the minimum value as a fourth fingerprint template of the finger;
01232: calculating the current matching degree between each fingerprint image and the image template of each fourth fingerprint template;
01233: and taking the fourth fingerprint template corresponding to the current matching degree with the value larger than the first matching degree as the first fingerprint template matched with the first fingerprint data.
Referring back to fig. 2, in some embodiments, steps 01231, 01232, and 01233 can be implemented by processor 20. That is, the processor 20 may be further configured to calculate a fourth difference between each first touch pressure and each second touch pressure in each finger, respectively, take the fingerprint template corresponding to the fourth difference with the smallest value as the fourth fingerprint template of the finger, calculate a current matching degree between each fingerprint image and the image template of each fourth fingerprint template, and take the fourth fingerprint template corresponding to the current matching degree with a value greater than the first matching degree as the first fingerprint template matching the first fingerprint data.
In particular, when the processor 20 acquires the first fingerprint data, the first fingerprint data needs to be matched with the fingerprint template. The first fingerprint data include two data, namely a fingerprint image and a first touch pressure, when the fingerprint image enables a shortcut function through the electronic device 100 for a user, the fingerprint identification module 10 acquires an image of a finger of the user, and the first touch pressure refers to a pressure of the finger touching the display screen 30 when the user enables the shortcut function through the electronic device 100. Every finger all has a plurality of fingerprint templates, every fingerprint template all includes image template and second touch pressure, the fingerprint image that fingerprint identification module 10 acquireed when the image template passes through the user-defined fingerprint combination of electronic equipment 100 and swift function's corresponding relation for the user, when second touch pressure passes through the user-defined fingerprint combination of electronic equipment 100 and swift function's corresponding relation, the user does not touch the pressure of display screen 30 with the finger under the condition of electronic equipment 100 suggestion, the second touch pressure inequality of a plurality of fingerprint templates of same finger.
Assume that there are two first fingerprint data, F1、F2First fingerprint data F1The fingerprint image in (1) is FI1The first touch pressure is FN1First fingerprint data F2The fingerprint image in (1) is FI2The first touch pressure is FN2(ii) a Four fingerprint templates are provided, and are respectively T1、T2、T3、T4Wherein, the fingerprint template T1And T2Being a fingerprint template for a finger, fingerprint template T3And T4A fingerprint template for another finger, fingerprint template T1The image template in (1) is TI1The second touch pressure is TN1Fingerprint template T2The image template in (1) is TI2The second touch pressure is TN2Fingerprint templateT3The image template in (1) is TI3The second touch pressure is TN3Fingerprint template T4The image template in (1) is TI4The second touch pressure is TN4. The processor 20 first calculates the first touch pressures F respectivelyN1And a second touch pressure TN1Second touch pressure TN2A fourth difference therebetween, and calculating the first touch pressure F, respectivelyN1And a second touch pressure TN3Second touch pressure TN4A fourth difference therebetween. Subsequently, the processor 20 derives the first touch pressure FN1And a second touch pressure TN1First touch pressure FN1And a second touch pressure TN2Selecting a fourth difference value with a smaller value from the fourth difference values, taking the fingerprint template corresponding to the fourth difference value as a fourth fingerprint template, and assuming that the fourth fingerprint template is T1The processor 20 also derives a first touch pressure FN1And a second touch pressure TN3First touch pressure FN1And a second touch pressure TN3Selecting a fourth difference value with a smaller value from the fourth difference values, taking the fingerprint template corresponding to the fourth difference value as a fourth fingerprint template, and assuming that the fourth fingerprint template is T4. Subsequently, the processor 20 calculates the fingerprint images as F respectivelyI1With a fourth fingerprint template T1、T4Current degree of match M between11、M14Processor 20 slave M11And M14Selecting a fourth fingerprint template with a value greater than the first matching degree as the first fingerprint data F1Matching first fingerprint template, suppose M11If it is greater than the first matching degree, the processor 20 considers M11Corresponding fourth fingerprint template T1I.e. with the first fingerprint data F1A matching first fingerprint template. If M is11And M14Are less than the first matching degree, the processor 20 recognizes the first fingerprint data F1The first fingerprint template matched with the plurality of fingerprint templates cannot be found, and the current shortcut function fails to be started. Finding and first fingerprint data F2Matching first fingerprint template with search and first fingerprint data F1Matched first fingerThe pattern template is the same, and is not described in detail herein.
It can be understood that when the pressure of the user touching the display screen 30 is different, the fingerprint images acquired by the fingerprint identification module 10 are also different. In order to quickly and accurately determine whether a first fingerprint template matched with first fingerprint data exists in a plurality of fingerprint templates, for each finger, the electronic device 100 may pre-store a plurality of fingerprint templates under different second touch pressures, and in the process of actually starting the shortcut function, the processor 20 may first perform screening of the fingerprint templates according to a fourth difference between the first touch pressure and the second touch pressure, and then match the fingerprint image with an image template in the screened fourth fingerprint template.
Referring to fig. 11, in some embodiments, before step 011, the enabling method further includes:
051: selecting a shortcut function as a shortcut function to be bound;
052: when the fingers of the user touch the display screen 30, acquiring a second touch pressure of each finger touching the display screen 30 and a fingerprint image of each finger for multiple times, wherein the second touch pressures of each finger touching the display screen 30 are different;
053: taking the fingerprint image of each finger when the finger touches the display screen 30 each time as an image template, and packaging the image template of the finger and the second touch pressure of the finger into a fifth fingerprint template;
054: forming a plurality of fifth fingerprint templates into a fingerprint combination to be bound, wherein the plurality of fifth fingerprint templates forming the fingerprint combination to be bound are fingerprint templates of different fingers; and
055: and binding the fingerprint combination to be bound with the shortcut function to be bound.
Referring back to fig. 2, in some embodiments, step 051, step 053, step 054 and step 055 can all be implemented by processor 20. Step 052 may be implemented by the display screen 30 and the fingerprint recognition module 10 together. That is, the processor 20 may be configured to select a shortcut function as the shortcut function to be bound. When the user's finger touches the display screen 30, the display screen 30 is used for obtaining the second touch pressure fingerprint identification module 10 that every finger touched the display screen 30 many times and is used for obtaining the fingerprint image of every finger many times, and every finger touches the second touch pressure homodyne of the display screen 30 at every turn and is different. The processor 20 is further configured to use a fingerprint image of each finger when the finger touches the display screen 30 each time as an image template, encapsulate the image template of the finger and the second touch pressure of the finger into a fifth fingerprint template, form a plurality of fifth fingerprint templates into a to-be-bound fingerprint combination, and bind the to-be-bound fingerprint combination and the to-be-bound shortcut function, where the plurality of fifth fingerprint templates forming the to-be-bound fingerprint combination are fingerprint templates of different fingers.
When the fingerprint combination is bound to the shortcut function, the electronic device 100 needs to acquire a second touch pressure of the finger touching the display screen 30 and a fingerprint image of the finger when the user touches the display screen 30. Specifically, in the interface for binding the fingerprint combination and the shortcut function, a plurality of shortcut functions available for the user to select, such as displaying the shortcut functions of copying, pasting, full selecting, deleting, closing, and canceling, are displayed on the display screen 30. After the user touches the display screen 30, the processor 20 determines the shortcut function selected by the user according to the position where the user touches the display screen 30, and takes the shortcut function selected by the user as the shortcut function to be bound. Assuming that the to-be-bound shortcut function is a copy, the electronic device 100 prompts the user to perform an operation of placing a plurality of fingers in the fingerprint identification area for multiple times, and when the fingers are placed in the fingerprint identification area each time, the pressure of the fingers touching the display screen 30 is different, the display screen 30 obtains the second touch pressure of each finger of the user for multiple times, and the fingerprint identification module 10 obtains the fingerprint image of each finger for multiple times. The fingerprint identification module 10 sends the fingerprint image of each finger touching the display screen 30 each time to the processor 20. Subsequently, the processor 20 takes the fingerprint image of each finger touching the display screen 30 at a time as an image template, and encapsulates the image template of each finger and the second touch pressure of the finger when touching the display screen 30 at the time as a fifth fingerprint template. Subsequently, the processor 20 selects a fifth fingerprint template from the plurality of fifth fingerprint templates of each finger, forms the selected plurality of fifth fingerprint templates into a fingerprint combination to be bound, and finally binds the fingerprint combination to be bound with the shortcut function to be bound.
Further, for the embodiment shown in steps 051 to 055, prior to step 051, the enabling method further comprises: and identifying the identity of the user, and executing the step 051 when the identity of the user is the owner. The identification of the user may be implemented by fingerprint identification, face identification, iris identification, voiceprint identification, digital password, pattern password, and the like, which is not limited herein. In the embodiment shown in steps 051 to 055, the processor 20 does not determine whether the acquired fingerprints are all fingerprints of the owner, so to ensure that only the owner can set the corresponding relationship between the shortcut function and the fingerprint combination, the processor 20 needs to identify the identity of the user first, and then displays the interface defining the corresponding relationship between the shortcut function and the fingerprint combination when the identity of the user is the owner.
In some embodiments, when the user customizes the corresponding relationship between the fingerprint combination and the shortcut function, the electronic device 100 may prompt the user about the form of the fingerprint combination. The electronic device 100 can count the use frequency of each finger (at this time, the fingerprint template is required to be pre-stored in the electronic device 100) and the use frequency of each shortcut function in the process of the user using the electronic device 100 at ordinary times, and then make a recommendation for the fingerprint combination corresponding to the to-be-bound shortcut function according to the use frequency of each finger and the use frequency of the shortcut function. Therefore, the user does not need to think which fingers are used for binding the to-be-bound shortcut function, and the intelligence of the electronic device 100 and the use experience of the user are improved.
As before, the fingerprint identification module can be capacitive fingerprint module 12, optical fingerprint module 15 or supersound fingerprint module etc..
