The embodiment of the present application provides a method for calibrating a threshold of a pressure key, which can be applied to theelectronic device 100.
As shown in fig. 5, the method for calibrating the pressure key threshold may include the following steps:
and 110, acquiring a plurality of pressing pressure values through the pressure sensor, wherein each pressing pressure value is greater than a first pressure threshold value.
During the use of the electronic device by the user, the electronic device can acquire a plurality of pressing pressure values of the user through the pressure sensor. For example, each time the user presses the pressure key, the electronic device responds to the pressing operation of the user, and the electronic device may acquire and record a pressing pressure value detected by the pressure sensor.
The electronic equipment is provided with a first pressure threshold value aiming at the pressure key. For example, the first pressure threshold may be 2N (newtons). The first pressure threshold represents a boundary line between a pressure value when the user successfully presses the pressure key and a pressure value when the user unsuccessfully presses the pressure key. That is, when the pressing pressure value of the user pressing the pressure key is greater than the first pressure threshold, the user is indicated to successfully press the pressure key, and at this time, the electronic device responds to the pressing operation of the user. And when the pressing pressure value of the user pressing the pressure key is smaller than or equal to the first pressure threshold value, the user does not successfully press the pressure key, and the error operation of the user may be performed at this time, so that the electronic device may not respond to the pressing operation of the user.
The electronic equipment obtains a plurality of pressing pressure values through the pressure sensor, wherein each pressing pressure value is larger than the first pressure threshold value.
And 120, sorting the plurality of pressing pressure values according to the size of each pressing pressure value to obtain a sorting queue.
After the electronic equipment acquires a plurality of pressing pressure values, the pressing pressure values can be sequenced according to the magnitude of each pressing pressure value, so that a sequencing queue is obtained. For example, if the number of the press pressure values acquired by the electronic device is 30, the 30 press pressure values may be sorted from small to large or from large to small to obtain a sorting queue.
And 130, acquiring an Nth pressing pressure value from the sorting queue according to a preset rule, wherein N is a positive integer.
The electronic device may be provided with a preset rule. The preset rule is used for acquiring a certain pressing pressure value from a sequencing queue obtained by the electronic equipment. For example, the preset rule may be the first pressing pressure value from the head of the sorting queue to the back, or may also be the first pressing pressure value from the tail of the sorting queue to the front.
After the electronic equipment obtains the sorting queue, the Nth pressing pressure value can be obtained from the sorting queue according to the preset rule. Wherein N is a positive integer. For example, N may be 10, 20, etc.
140, calibrating the first pressure threshold according to the nth compression pressure value.
After the electronic device obtains the nth pressing pressure value from the sorting queue, the first pressure threshold value can be calibrated according to the nth pressing pressure value.
Because the electronic device obtains a plurality of pressing pressure values in the using process of the user and obtains the Nth pressing pressure value from the plurality of pressing pressure values, after the first pressure threshold value is calibrated according to the Nth pressing pressure value, the calibrated pressure threshold value is closer to the using habit of the user. Therefore, the pressure key can more accurately detect the pressing operation of the user, and the occurrence of misoperation can be reduced.
In some embodiments, as shown in fig. 6,step 110, acquiring a plurality of compression pressure values by the pressure sensor, comprises the steps of:
111, when the pressure sensor detects a pressing pressure value, judging whether the pressing pressure value is greater than a first pressure threshold value;
112, if the pressing pressure value is greater than the first pressure threshold, determining whether the duration of the pressure sensor continuously detecting the pressing pressure value is greater than a preset duration;
113, if the duration of the pressure sensor continuously detecting the pressing pressure value is longer than the preset duration, storing the pressing pressure value, and increasing the count of the pressing pressure value by 1;
and 121, when the count of the pressing pressure values reaches a preset number, sorting the plurality of stored pressing pressure values according to the size of each pressing pressure value to obtain a sorting queue, wherein the preset number is greater than N.
During the use of the electronic device by the user, the electronic device may count the number of valid presses of the pressure key by the user.
When the pressure sensor in the pressure key detects a pressing pressure value, the electronic equipment judges whether the pressing pressure value is larger than a first pressure threshold value. If the pressing pressure value is not greater than the first pressure threshold value, that is, is less than or equal to the first pressure threshold value, it is determined that the pressing pressure of the pressing operation detected this time is too small. The operation detected this time can be regarded as a malfunction. The misoperation is a pressing operation caused by the fact that the user touches the pressure key unintentionally or another object (such as a table, a backpack, etc.) except the user touches the pressure key.
If the pressing pressure value is larger than the first pressure threshold value, the electronic equipment continues to judge whether the duration of the pressing pressure value continuously detected by the pressure sensor is larger than a preset duration. The preset time duration is a time duration value preset in the electronic device, for example, 100ms (milliseconds). The preset duration is used for further judging whether the pressing operation detected by the pressure key is misoperation. If the duration of the pressure value detected by the pressure sensor is not longer than the preset duration, that is, is less than or equal to the preset duration, it indicates that the duration of the detected pressing operation is too short. Then, the operation detected this time may also be regarded as an erroneous operation.
If the duration of the pressure sensor continuously detecting the pressing pressure value is longer than the preset duration, which indicates that the pressing pressure of the pressing operation detected by the pressure sensor at this time and the duration of the pressing operation both meet the conditions, the detected pressing operation is considered to be effective operation. At this time, the electronic device may store the detected pressing pressure value and increase the count of pressing pressure values by 1.
When the counting of the electronic equipment on the pressing pressure values reaches a preset number, the electronic equipment sorts the stored pressing pressure values according to the size of each pressing pressure value so as to obtain a sorting queue. Wherein the preset number is a value set in the electronic device. The preset number is greater than N. For example, the preset number may be 100. That is, each time the count of the press pressure values by the electronic device reaches 100, the electronic device may sort the stored 100 press pressure values and perform the subsequent pressure threshold calibration operation.
In some embodiments, as shown in fig. 6,step 140, calibrating the first pressure threshold according to the nth compression pressure value, comprises the steps of:
141, calculating a second pressure threshold according to the nth pressing pressure value and a preset pressure offset;
142, replacing the first pressure threshold with the second pressure threshold.
Wherein, the electronic equipment is provided with a preset pressure offset. The preset pressure offset is a pressure value. For example, the preset pressure offset may be 1N (newton).
After the electronic device obtains the nth pressing pressure value from the sorting queue, the second pressure threshold may be calculated according to the nth pressing pressure value and the preset pressure offset. Subsequently, the first pressure threshold is replaced with the second pressure threshold to enable calibration of the first pressure threshold. For example, if the first pressure threshold is 2N (newton) and the calculated second pressure threshold is 3N (newton), the electronic device replaces the first pressure threshold with 3N (newton), thereby completing the update of the pressure thresholds of the pressure keys in the electronic device.
In practical applications, the electronic device may continue to perform the above-mentioned pressure threshold calibration operation during the use of the user. That is, when the count of the pressed pressure values in the electronic device reaches the preset number, the pressure threshold of the pressure key can be calibrated, so that the pressure threshold of the pressure key can be continuously calibrated, and the detection sensitivity of the pressure key is better adapted to the use habit of a user.
In some embodiments, when calculating the second pressure threshold according to the nth compression pressure value and the preset pressure offset amount, the electronic device calculates according to the following formula:
F2＝FN+Foffset
wherein, F2Is said second pressure threshold, FNIs the Nth pressing pressure value, FoffsetIs the preset pressure offset.
For example, the nth pressing pressure value F acquired by the electronic deviceNIs 2N (Newton), and the offset F of the preset pressureoffsetIs 1N (newton), then a second calculated pressure threshold F is obtained2It is 3N (Newton).
In some embodiments, as shown in fig. 7, thestep 120 of sorting the plurality of pressing pressure values according to the magnitude of each of the pressing pressure values to obtain a sorting queue includes the following steps:
122, arranging the plurality of pressing pressure values in a descending order according to the magnitude of each pressing pressure value to obtain a descending order queue;
131, obtaining the Nth last pressing pressure value from the descending queue.
After the electronic device obtains the plurality of pressing pressure values, the plurality of pressing pressure values can be arranged in a descending order according to the size of each pressing pressure value, namely, the pressing pressure values are arranged in a descending order, so that a descending order queue is obtained. Subsequently, the electronic device obtains the Nth last pressing pressure value from the descending queue.
For example, the electronic device acquires 100 pressing pressure values. According to the principle of 10% failure in the pressing operation, the nth pressing pressure value acquired by the electronic device is the 11 th last pressing pressure value in the descending queue, namely the 11 th pressing pressure value from the tail to the front in the descending queue. Then N is 11 at this time.
In some embodiments, as shown in fig. 8, thestep 120 of sorting the plurality of pressing pressure values according to the magnitude of each of the pressing pressure values to obtain a sorting queue includes the following steps:
123, arranging the plurality of pressing pressure values in an ascending order according to the magnitude of each pressing pressure value to obtain an ascending order queue;
132, obtaining the Nth pressing pressure value from the ascending queue.
After the electronic device obtains the plurality of pressing pressure values, the plurality of pressing pressure values may be arranged in an ascending order according to the magnitude of each pressing pressure value, that is, in a descending order, so as to obtain an ascending order queue. Subsequently, the electronic device obtains the Nth pressing pressure value from the ascending queue.
For example, the electronic device acquires 100 pressing pressure values. According to the principle of 10% failure in the pressing operation, the nth pressing pressure value acquired by the electronic device is the 11 th pressing pressure value in the ascending queue, namely the 11 th pressing pressure value from the head of the queue to the back of the ascending queue. Then N is 11 at this time.
In particular implementation, the present application is not limited by the execution sequence of the described steps, and some steps may be performed in other sequences or simultaneously without conflict.
As can be seen from the above, the method for calibrating a threshold of a pressure button provided in the embodiment of the present application includes: acquiring a plurality of pressing pressure values through a pressure sensor, wherein each pressing pressure value is greater than a first pressure threshold value; sequencing the plurality of pressing pressure values according to the size of each pressing pressure value to obtain a sequencing queue; acquiring an Nth pressing pressure value from the sorting queue according to a preset rule, wherein N is a positive integer; calibrating the first pressure threshold according to the Nth compression pressure value. In the method for calibrating the pressure key threshold, because the electronic device obtains a plurality of pressing pressure values in the using process of the user and obtains the Nth pressing pressure value from the plurality of pressing pressure values, after the first pressure threshold is calibrated according to the Nth pressing pressure value, the calibrated pressure threshold is closer to the using habit of the user. Therefore, the pressure key can more accurately detect the pressing operation of the user, and the occurrence of misoperation can be reduced.
The embodiment of the present application further provides a calibration apparatus for a threshold of a pressure key, which may be integrated in theelectronic device 100.
As shown in fig. 9, the pressure keythreshold calibration apparatus 200 may include: afirst acquisition module 201, asorting module 202, asecond acquisition module 203, and acalibration module 204.
The first obtainingmodule 201 is configured to obtain a plurality of pressing pressure values through a pressure sensor, where each of the pressing pressure values is greater than a first pressure threshold.
During the use of the electronic device by the user, the first obtainingmodule 201 may obtain a plurality of pressing pressure values of the user through the pressure sensor. For example, each time the user presses the pressure button, the electronic device responds to the pressing operation of the user, the first obtainingmodule 201 may obtain a pressing pressure value detected by the pressure sensor, and record the pressing pressure value.
The electronic equipment is provided with a first pressure threshold value aiming at the pressure key. For example, the first pressure threshold may be 2N (newtons). The first pressure threshold represents a boundary line between a pressure value when the user successfully presses the pressure key and a pressure value when the user unsuccessfully presses the pressure key. That is, when the pressing pressure value of the user pressing the pressure key is greater than the first pressure threshold, the user is indicated to successfully press the pressure key, and at this time, the electronic device responds to the pressing operation of the user. And when the pressing pressure value of the user pressing the pressure key is smaller than or equal to the first pressure threshold value, the user does not successfully press the pressure key, and the error operation of the user may be performed at this time, so that the electronic device may not respond to the pressing operation of the user.
The first obtainingmodule 201 obtains, by using a pressure sensor, a plurality of pressing pressure values, each of which is greater than the first pressure threshold.
Thesorting module 202 is configured to sort the plurality of pressing pressure values according to the magnitude of each pressing pressure value, so as to obtain a sorting queue.
After the first obtainingmodule 201 obtains the plurality of pressing pressure values, thesorting module 202 may sort the plurality of pressing pressure values according to the magnitude of each pressing pressure value, so as to obtain a sorting queue. For example, if the number of the pressing pressure values acquired by the first acquiringmodule 201 is 30, thesorting module 202 may sort the 30 pressing pressure values in a descending order or a descending order, so as to obtain a sorting queue.
The second obtainingmodule 203 is configured to obtain an nth pressing pressure value from the sorting queue according to a preset rule, where N is a positive integer.
The electronic device may be provided with a preset rule. The preset rule is used for obtaining a certain pressing pressure value from the sorting queue obtained by thesorting module 202. For example, the preset rule may be the first pressing pressure value from the head of the sorting queue to the back, or may also be the first pressing pressure value from the tail of the sorting queue to the front.
After thesorting module 202 obtains the sorting queue, the second obtainingmodule 203 may obtain the nth pressing pressure value from the sorting queue according to the preset rule. Wherein N is a positive integer. For example, N may be 10, 20, etc.
Acalibration module 204, configured to calibrate the first pressure threshold according to the nth compression pressure value.
After the second obtainingmodule 203 obtains the nth pressing pressure value from the sorting queue, thecalibration module 204 may calibrate the first pressure threshold according to the nth pressing pressure value.
Since the pressure keythreshold calibration device 200 is a plurality of pressing pressure values obtained in the using process of the user and an nth pressing pressure value obtained from the plurality of pressing pressure values, after the first pressure threshold is calibrated according to the nth pressing pressure value, the calibrated pressure threshold is closer to the using habit of the user. Therefore, the pressure key can more accurately detect the pressing operation of the user, and the occurrence of misoperation can be reduced.
In some embodiments, the first obtainingmodule 201 is configured to perform the following steps:
when the pressure sensor detects a pressing pressure value, judging whether the pressing pressure value is greater than a first pressure threshold value;
if the pressing pressure value is greater than the first pressure threshold, judging whether the duration of the pressing pressure value continuously detected by the pressure sensor is greater than a preset duration;
if the pressure sensor continuously detects that the duration of the pressing pressure value is longer than the preset duration, storing the pressing pressure value, and increasing the count of the pressing pressure value by 1;
thesorting module 202 is configured to perform the following steps:
when the count of the pressing pressure values reaches a preset number, sequencing the plurality of stored pressing pressure values according to the size of each pressing pressure value to obtain a sequencing queue, wherein the preset number is greater than N.
During the use of the electronic device by the user, the first obtainingmodule 201 may count the number of valid presses of the pressure button pressed by the user.
When a pressure sensor in the pressure button detects a pressing pressure value, the first obtainingmodule 201 determines whether the pressing pressure value is greater than a first pressure threshold. If the pressing pressure value is not greater than the first pressure threshold value, that is, is less than or equal to the first pressure threshold value, it is determined that the pressing pressure of the pressing operation detected this time is too small. The operation detected this time can be regarded as a malfunction. The misoperation is a pressing operation caused by the fact that the user touches the pressure key unintentionally or another object (such as a table, a backpack, etc.) except the user touches the pressure key.
If the pressing pressure value is greater than the first pressure threshold, the first obtainingmodule 201 continues to determine whether the duration of the pressure sensor that continuously detects the pressing pressure value is greater than a preset duration. The preset time duration is a time duration value preset in the electronic device, for example, 100ms (milliseconds). The preset duration is used for further judging whether the pressing operation detected by the pressure key is misoperation. If the duration of the pressure value detected by the pressure sensor is not longer than the preset duration, that is, is less than or equal to the preset duration, it indicates that the duration of the detected pressing operation is too short. Then, the operation detected this time may also be regarded as an erroneous operation.
If the duration of the pressure sensor continuously detecting the pressing pressure value is longer than the preset duration, which indicates that the pressing pressure of the pressing operation detected by the pressure sensor at this time and the duration of the pressing operation both meet the conditions, the detected pressing operation is considered to be effective operation. At this time, the first obtainingmodule 201 may store the detected pressing pressure value and increase the count of the pressing pressure values by 1.
When the count of the pressing pressure values by the first obtainingmodule 201 reaches a preset number, thesorting module 202 sorts the stored pressing pressure values according to the magnitude of each pressing pressure value, so as to obtain a sorting queue. Wherein the preset number is a value set in the electronic device. The preset number is greater than N. For example, the preset number may be 100.

In practical applications, the pressure keythreshold calibration apparatus 200 may continue to perform the above-mentioned pressure threshold calibration operation during the use of the user.

wherein, F2Is said second pressure threshold, FNIs the Nth pressing pressure value, FoffsetIs the preset pressure offset.
For example, the Nth acquired pressing pressure value FNIs 2N (Newton), and the offset F of the preset pressureoffsetIs 1N (newton), then a second calculated pressure threshold F is obtained2It is 3N (Newton).

according to the magnitude of each pressing pressure value, performing descending arrangement on the plurality of pressing pressure values to obtain a descending queue;

According to the principle of 10% failure in the pressing operation, the nth pressing pressure value acquired by the second acquiringmodule 203 is the 11 th last pressing pressure value in the descending queue, that is, the 11 th pressing pressure value from the tail to the front in the descending queue. Then N is 11 at this time.

Subsequently, the second obtainingmodule 203 obtains the nth pressing pressure value from the ascending queue.
For example, the first acquiringmodule 201 acquires 100 pressing pressure values. According to the principle of 10% failure in the pressing operation, the nth pressing pressure value acquired by the second acquiringmodule 203 is the 11 th pressing pressure value in the ascending queue, that is, the 11 th pressing pressure value from the head of the queue to the back of the queue in the ascending queue.
