Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
With the updating of electronic products, in a boot system of an electronic device, a password unlocking mode has been gradually replaced by a mode of unlocking the device by using biometric information (fingerprint, palm print). The method includes the steps of identifying a touch action of a target object, namely, unlocking equipment by using biological characteristic information of the target object (for example, a fingerprint identification area is arranged below a screen of a mobile phone in the prior art and used for verifying identity information of an unlocking user), judging whether the user has an unlocking intention by judging whether an induction quantity of a touch screen exceeds a threshold value, and judging whether to awaken the screen to start a next biological characteristic information acquisition step by using a principle that the induction quantity of a pressed area on the touch screen is increased when the touch screen is pressed.
However, in the research process, the inventor finds that, when an identification algorithm mechanism is used as the only standard for waking up in the prior art, the wake-up mechanism may be triggered by mistake due to the collection of wrong data, which may cause the device to turn on, for example: in the process of performing ESD detection on a touch screen (the ESD standard is based on ISO9001 and is a specific requirement on an electrostatic discharge protection control system), the screen sensing quantity acquired by a sensor may change, so that a possibility of false triggering of a startup action exists, based on which, the invention provides a starting method, which is applied to a terminal, as shown in fig. 1, the method includes:
step S101, acquiring the induction quantity of a touch area in the terminal, and judging whether the induction quantity meets equipment starting conditions or not;
in the embodiment of the present invention, the sensing quantity is used to represent a touch quantity of the touch area, the sensing quantity (diffata) is a value used to represent a state change amplitude of the touch area in the terminal, and in practical applications, the action of acquiring the sensing quantity of the touch area in the terminal is completed by an IC circuit in the terminal, specifically, a sensor in the IC circuit acquires the state quantity of the touch area as base data (base), and then a chip (for example, TDDI) in the IC circuit performs a difference between original data (Rawdata) acquired by the sensor in a next frame and the base data to obtain the sensing quantity reflecting the state change amplitude of the touch area, and then sets the current original data as the base data, and continues to acquire the original data of the next frame and performs the difference, so as to calculate the sensing quantity cyclically.
In practical application, when no one touches the touch area on the terminal, the sensing quantity is unchanged, when a person presses the touch area with a finger or a palm, the sensing quantity is changed, and the characteristic can be used as an initial judgment condition for starting the terminal.
If yes, executing step S102 to obtain a compensation capacitance value for indicating the stress degree of the touch area;
in the embodiment of the present invention, when the sensing quantity satisfies the device start condition, an IC circuit may be used to acquire a compensation capacitance value (Cneg value) for indicating the stress degree of the touch area, where the compensation capacitance value may directly reflect the stress degree of the touch area, that is, whether the touch area is stressed may be directly and accurately determined on a physical layer, so as to eliminate the device start condition caused by electromagnetic interference or dirty data.
Step S103, determining a false touch judgment result according to the induction quantity and the compensation capacitance value;
in practical application, the sensing quantity is a state value of the touch area acquired by the IC circuit, and the compensation capacitance value is a stress degree value of the touch area acquired by the IC circuit, so that the situation of false triggering can be avoided by determining whether the pressure change area corresponds to the state change area, or the situation of false triggering can be determined by comparing the mapping relationship between the pressure change area and the state change area, and the specific setting can be determined according to the actual situation.
And step S104, if the error touch judgment result is that the error touch trigger is not generated, controlling the terminal to start.
In the embodiment of the invention, if the false touch judgment result is false touch trigger, the IC circuit can compensate the compensation capacitance value acquired by the sensor and update the original data, so that the subsequent original data and the induction quantity can be recovered to be normal, and the normal use of a user is ensured.
According to the method and the device, the induction quantity of the touch area in the terminal is obtained, and whether the induction quantity meets the equipment starting condition is judged; when the induction quantity meets the equipment starting condition, acquiring a compensation capacitance value used for representing the stress degree of the touch area; and determining a false touch judgment result according to the induction quantity and the compensation capacitance value, determining a pressed area in a physical touch area by acquiring the compensation capacitance value of the stress degree of the touch area, and judging whether the starting device instruction is false triggering or not by combining the induction quantity, so that the problem that a wake-up mechanism is false triggered due to the acquisition of false data can be effectively avoided.
In the conventional palm press starting process, generally, only a single data layer recognition algorithm is adopted, but the present invention obtains a compensation capacitance value for representing the stress degree of a touch area, and can determine the stressed area in a physical touch area, so as to avoid that a terminal is falsely triggered to start due to acquisition of wrong data, and further can determine whether a pressure change area corresponds to a state change area, specifically, as shown in step S103, a step of determining a false touch determination result according to the induction quantity and the compensation capacitance value, and as shown in fig. 2, includes:
step S201, determining a first reference touch area in the touch area corresponding to the induction quantity;
step S202, determining a second reference touch area in the touch area corresponding to the compensation capacitance value;
step S203, determining a false touch determination result according to the first reference touch area and the second reference touch area.
In the embodiment of the present invention, a specific way of determining the false touch determination result according to the sensing quantity and the compensation capacitance value is to determine whether the pressure change area corresponds to the state change area, that is, first determine a first reference touch area in the touch area corresponding to the sensing quantity, and then determine a second reference touch area in the touch area corresponding to the compensation capacitance value.
Further, since the arrangement design of the IC circuits is different, there often exists a mapping relationship between the collected compensation capacitance and the sensing quantity, and based on this, step S203 determines a false touch determination result according to the first reference touch area and the second reference touch area, as shown in fig. 3, includes:
step S301, acquiring a preset mapping relation;
in an embodiment of the present invention, a mapping relationship may be provided by a manufacturer of the IC circuit, where the mapping relationship is used to represent a corresponding relationship between the sensing quantity and the compensation capacitance value, and in practical applications, an array formed by the compensation capacitance values collected by a sensor in the IC circuit often does not correspond to an array formed by the sensing quantity, for example: the element of the ith row and the jth column in the compensation capacitor array corresponds to the first module in the touch area, and the element of the ith row and the jth column in the induction quantity array corresponds to the second module in the touch area.
Step S302, converting the second reference touch area into a standard touch area according to the mapping relation;
in an embodiment of the present invention, in order to make corresponding position elements in the first reference touch area and the second reference touch area correspond to modules in the touch area, the second reference touch area is converted into a standard touch area according to the mapping relationship, so that the arrangement mode of the standard touch area is the same as that of the first reference area.
Step S303, determining a false touch determination result according to the standard touch area and the first reference touch area.
In the embodiment of the present invention, the second reference touch area is converted into the standard touch area according to the mapping relationship, so as to directly determine whether the standard touch area and the first reference touch area correspond to the same touch area (screen module).
Further, in step S303, the step of determining a result of the erroneous touch determination according to the standard touch area and the first reference touch area, as shown in fig. 4, includes:
step S401, if the standard touch area is not located in a preset edge area of the touch area, traversing a plurality of compensation capacitance values in the standard touch area;
in the embodiment of the present invention, the edge area is an area including at least modules at the edge of the touch area (top, bottom, right, and left), but not limited to only the top, bottom, right, and left modules, and for a case that the standard touch area is not located in a predetermined edge area of the touch area, the plurality of compensation capacitance values in the standard touch area are traversed (i.e., the traversal is started from the first row and the first column in the compensation capacitor array of the standard touch area).
Step S402, when the compensation capacitance value is determined to meet the preset condition, determining the compensation capacitance value as an initial compensation capacitance value;
in the embodiment of the present invention, the preset condition may be determined according to a posteriori knowledge, that is, the compensation capacitance value of the pressed area in the touch area is recorded in multiple implementations, and when the compensation capacitance value is traversed to be within the preset condition range, the compensation capacitance value may be determined as the initial compensation capacitance value, so as to further determine the pressing range.
Further, in another embodiment of the present invention, a preferable setting implementation of a preset condition is further provided, where the preset condition includes one of:
the difference values between the currently traversed compensation capacitance value and the traversed compensation capacitance values in the same column and/or the same row in the compensation capacitance value array are both larger than a first preset threshold value;
the difference values between the currently traversed compensation capacitance values and the compensation capacitance values traversed by the compensation capacitance values in the same column and/or the same row in the compensation capacitance value array are both greater than a second preset threshold value, wherein the second preset threshold value is less than the first preset threshold value.
For example, as shown in fig. 5, for example, the first preset threshold is 2, the compensation capacitance value is traversed from the first row to the first column until the seventh row is traversed, and when the sixth row is traversed to the sixth column of the eighth row, "50" of the sixth column of the eighth row is greater than "47" of the fifth column of the traversed eighth row and greater than "47" of the sixth column of the seventh row, that is, the difference between the currently traversed compensation capacitance value and the traversed compensation capacitance value located in the same column and/or the same row is greater than the first preset threshold.
Similarly, the second predetermined threshold needs to be smaller than the first predetermined threshold, and in order to ensure the universality of the algorithm can be determined according to empirical values, as described above, specifically, in practical applications, the intermediate portion (for example, rows 17 and 18) may be traversed, and if the current compensation capacitance and the traversed compensation capacitance are sequentially subtracted, the complexity of the algorithm is increased, so preferably, the predetermined condition is as follows:
condition 1: CnegNew (i, j) -CnegNew (i-1, j) > CnegNew RowGap
Condition 2: CnegNew (i, j) -CnegNew (i-2, j) > CnegNew RowGap
Condition 3: CnegNew (i, j) -CnegNew (i, j-1) > CnegNew RowGap
Condition 4: CnegNew (i, j) -CnegNew (i, j-1) > CnegNewColGap
Condition 5: CnegNew (i, j) < CnegNew (i +1, j)
Wherein, CnegNew (i, j) is the compensation capacitance value of the ith row and the jth column in the standard touch area, and CnegNewRowGap and CnegNewColGap are preset threshold values;
accordingly, the step of determining that the compensation capacitance value satisfies a preset condition includes:
determining the position of the compensation capacitance value in the standard touch area to be CnegNew (i, j);
if the compensation capacitance value meets the conditions 1, 3 and 5, determining that the compensation capacitance value meets a preset condition;
or if the compensation capacitance value meets the conditions 2, 3 and 5, determining that the compensation capacitance value meets a preset condition;
or if the compensation capacitance value meets the conditions 1, 4 and 5, determining that the compensation capacitance value meets a preset condition;
or, if the compensation capacitance value satisfies the conditions 2, 4 and 5, determining that the compensation capacitance value satisfies a preset condition.
Wherein i and j are both positive integers.
In this step, for different compensation capacitance values of different touch modules (display screens), the embodiment of the present invention compares the current compensation capacitance value in the traversal mechanism with the adjacent compensation capacitance value, so as to achieve the purpose of quickly determining whether the current compensation capacitance value is the edge of the pressed area, and meanwhile, improve the universality of the algorithm, and can be applied to different touch modules.
Step S403, in the standard touch area, calculating the number of compensation capacitance values larger than the initial compensation capacitance value in four quadrants with the initial compensation capacitance value as a center to obtain an initial compensation capacitance value;
in the embodiment of the present invention, a rectangular coordinate system is established in an array including a plurality of compensation capacitance values with the initial compensation capacitance value as the center (as shown in fig. 5, the area traversed by the initial compensation capacitance value is "50"), and the number of compensation capacitance values having the same value as the initial compensation capacitance value is counted to obtain the initial compensation capacitance value.
Step S404, calculating the similarity of the first reference touch area;
step S405, if the similarity of the first reference touch area is greater than a first similarity threshold, and the initial compensation capacitance is greater than the maximum compensation capacitance reference amount corresponding to the first similarity threshold, determining that the false touch determination result is a non-false touch trigger.
In the embodiment of the present invention, the similarity is calculated as follows: number set a ═ i, j, R, number set B ═ i, j, D, then three-dimensional data set A, B similarity degrees
Wherein i, j and n are positive integers, and R is original data, that is, R ═ (x1, x2, x3, …, xn-1, xn); d is the sensing amount, that is, D ═ y1, y2, y3, …, yn-1, yn), and according to the similarity, the embodiment of the present invention can determine whether there is a palm pressing and the size of the area pressed. Theoretically, the larger the single sensing amount (degree of pressing force), the larger the touch area (raised part in the compensation capacitance array), and the greater the similarity between the two. Whether the processing mechanism (corresponding to different compensation capacitance) under different pressing conditions (such as large-area pressing of palm, slight touch of single finger, etc.) is entered can be judged according to the similarity.
The maximum compensation capacitance reference (Cneghith value) is a posteriori empirical value, and the minimum compensation capacitance reference (Cnegloth value) is also corresponding to the maximum compensation capacitance reference, specifically, both the Cnegloth value and the Cneghith value can be determined according to the actual configuration condition of the terminal, and it is usually required to satisfy that the Cneghith value is greater than the Cnegloth value.
In addition, if the similarity of the first reference touch area is greater than a second similarity threshold and smaller than a first similarity threshold, whether the initial compensation capacitance is greater than a preset minimum compensation capacitance reference corresponding to the second similarity threshold is judged;
and if the initial compensation capacitance is larger than the preset minimum compensation capacitance reference amount, determining that the error touch judgment result is non-error touch triggering.
In the embodiment of the present invention, in consideration of the situation of light pressing by the user, in order to ensure accuracy in false trigger detection, a second similarity threshold smaller than the first similarity threshold and a Cnegloth value smaller than the Cneghith value are further provided, and the implementation process is the same as that in the above embodiment, which is not described herein again.
In the embodiment of the invention, if the standard touch area is located in a preset edge area of the touch area, and the similarity between the first reference touch area and the standard touch area is greater than a preset similarity threshold, determining that the mistaken touch judgment result is not mistaken touch trigger;
in the embodiment of the present invention, in a case where the standard touch area is located in a preset edge area of the touch area, since the compensation capacitance value in the standard touch area cannot be compared with an adjacent value (if the standard touch area is located at the edge, there is no adjacent value) according to a preset condition, it can be directly determined that the erroneous touch determination result is the non-erroneous touch trigger.
However, in practical applications, even if the standard touch area is located in the preset edge area of the touch area, different combinations of conditions may be set to determine whether the currently traversed compensation capacitance is a convex edge value (initial compensation capacitance).
For example: if the edge area is the top, bottom, left and right most edge row, the number of rows and columns is (i, j), wherein i belongs to (0, RowMax), j belongs to (0, ColMax), and if the edge area is at the left edge (i.e. i belongs to (1, RowMax-1), j equals to 0), whether the conditions 1 and 5 are met is judged; if the position is at the upper edge (namely j belongs to (1, ColMax-1), and i is equal to 0), judging whether the conditions 3, 4 and 5 are met; if the position is at the right edge (i.e., i belongs to (1, RowMax-1), and j is ColMax), whether the conditions 1, 3, 4, and 5 are met is judged; if the position is at the lower edge (namely j belongs to (1, RowMax-1), and i is equal to RowMax), judging whether conditions 1, 2, 3 and 4 are met; if the position is at the upper left corner (i is 0, and j is 0), judging whether a condition 5 is met; if the position is at the upper right corner (i is 0, and j is ColMax), judging whether the conditions 3, 4 and 5 are met; if the position is at the lower left corner (i ═ RowMax, j ═ 0), whether conditions 1 and 2 are met is judged; if the position is at the lower right corner (i is 0, j is ColMax), it is determined whether the conditions 1, 2, 3, and 4 are satisfied, in the above case, if so, the compensation capacitance value is set to determine the initial compensation capacitance value, and the subsequent processing flow equivalent to the non-edge area is not repeated here.
In another embodiment of the present invention, step S101, determining whether the sensing quantity satisfies a device start condition, as shown in fig. 6, includes:
step S601, judging whether the induction quantity is larger than a preset induction quantity threshold value;
in the embodiment of the present invention, the sensing quantity threshold is a threshold determined according to a posteriori knowledge, the sensing quantity (diffata) in practical application is a value used for representing a state change amplitude of a touch region in a terminal, and in practical application, the action of acquiring the sensing quantity of the touch region in the terminal is completed by an IC circuit in the terminal, specifically, a sensor in the IC circuit acquires the state quantity of the touch region as base data (base), then a chip (for example, TDDI) in the IC circuit performs a difference between raw data (Rawdata) acquired by the sensor in a next frame and the base data to obtain the sensing quantity for reflecting the state change amplitude of the touch region, then the current raw data is set as the base data, and the raw data acquired in the next frame is continuously acquired and is subjected to the difference, so as to calculate the sensing quantity cyclically.
According to the embodiment of the invention, the pressing condition of daily non-active touch behavior (for example, the touch screen is put in a pocket and is squeezed) can be eliminated by preliminarily judging whether the induction quantity is greater than the preset induction quantity threshold value.
If yes, step S602, determining whether the number of continuous frames is greater than a preset duration when the induction quantity is greater than a preset induction quantity threshold;

If yes, step S603, determining whether the similarity characteristic of the induction quantity satisfies a similarity characteristic threshold.
In the embodiment of the present invention, if the number of continuous frames is greater than the preset duration when the sensing amount is greater than the preset sensing amount threshold, the similarity calculation method may refer to the above-mentioned embodiment, and will not be described herein again, and according to the theory that the greater the sensing amount (pressing force) of a single Sensor, the greater the touch area (the greater the number of sensors to be pressed), and the greater the similarity between the two sensors, whether to enter into a processing mechanism under different pressing situations (such as large-area pressing with a palm, or slight touch with a single finger, etc.) is determined according to the similarity.
