Fig. 1 is a schematic flow chart of a method for correcting a key misjudgment in an embodiment of the present application, where an execution main body of the method may be a terminal device, and as shown in fig. 1, the method for correcting a key misjudgment may include the following steps:
step S101, obtaining the key values to be processed at intervals of a first preset period.
In this embodiment, the capacitive touch key is more sensitive to various interferences because it detects a small change in the electrical quantity. For example, interference of power supply voltage, static electricity, temperature and humidity of the device in different environments, or interference caused by differences in the manufacturing process easily causes that after key touch is finished, the current state is judged to be in the key touch state by mistake due to inaccuracy of detection results, and therefore, the terminal needs to process the key value to be processed after obtaining the key value to be processed at intervals of a first preset period, so as to accurately judge whether the key is touched currently or not, or whether touch is released or not, namely, touch is finished. The first predetermined period may be set to 200ms.
It is understood that any two conductive objects have an induced capacitance therebetween, and one key, i.e., one pad and the ground, can also form an induced capacitance therebetween. The value of the sensing capacitor is a fixed and unchanging tiny value under the condition that the surrounding environment is unchanged. When a human finger is close to the touch key, the total induction capacitance value can be increased by the induction capacitance formed by the human finger and the ground and the induction capacitance formed by the parallel connection pad and the ground. And after the capacitive touch key IC detects that the value of the induction capacitor of a certain key changes, a determination signal that the certain key is pressed is output, so that response is triggered.
In one embodiment, before step S101, the method includes: when the initialization of the equipment is detected, acquiring an initial key value; and setting the product of the initial key value and a preset threshold calculation coefficient as a key threshold.
In this embodiment, after detecting that the device is initialized, the terminal device obtains a current initial key value, multiplies the initial key value by a preset threshold calculation base number to obtain a key threshold, and determines the key threshold according to the initialized key value, so that the accuracy of determining the key threshold is improved, and the subsequent determination result is more accurate. The preset threshold calculation coefficient may be set to 96%, and the determination threshold may be decreased by decreasing the threshold calculation coefficient, so as to improve the sensitivity of the touch operation.
Further, the terminal device may set a touch sensitivity fine-tuning interface to adjust the threshold setting during touch operation determination, so that the user can adjust the threshold setting as required, thereby being able to handle the response sensitivity problem that has not been covered.
It can be understood that, in the key touch process, the key threshold set when the key is touched is different according to different touch key designs, and may include two cases, that is, the set key threshold is lower than the key value when the touch operation occurs and the set key threshold is higher than the key value when the touch operation occurs, in the embodiment of the present application, the case where the key threshold set when the key is touched is higher than the key value when the touch operation occurs is taken as an example for explanation, that is, when the touch operation occurs, the acquired key value is lower than the key threshold; and when the key is not touched, the key value is higher than the key threshold value. The key misjudgment condition that the key still recognized as the touch state after touch release occurs is generally because the key value after touch and release does not recover to be higher than the set key threshold value.
In one embodiment, before step S101, the method includes: and when the initialization of the equipment is detected, acquiring a second preset number of key data sets, and respectively carrying out filtering processing on the second preset number of key data sets to obtain corresponding target key values. Carrying out mean value processing on a second preset number of target key values to obtain initial key values; and calculating the product of the initial key value and the threshold calculation coefficient to obtain the key threshold, and improving the accuracy of determining the key threshold, so that the subsequent judgment result is more accurate. Wherein, the second preset number may be 5.
In one embodiment, the threshold may be made more accurate by delaying the acquisition of the threshold in the face of inaccuracies in the threshold due to interference from user touches or from key sampling while the device is powered on. For example, in the face of the problem of voltage drop caused by large current of other modules when the device is powered on, the initial key threshold value can be determined after a period of time is delayed after the device is powered on, so that the interference is avoided by key initialization, and the accuracy of the initial threshold value is improved. And if the sampling value read normally by the touch key is set to be S1 and the sampling value in the power-on process is set to be S2, (S1-S2)/S1 > +/-5 percent, the threshold value is delayed for a period of time if the sampling value in the current power-on process influences the threshold value, and then the threshold value is determined.
Step S102, when the key value to be processed is smaller than a preset key threshold, obtaining a first preset number of key values at intervals of a second preset period to obtain a key data set; the second predetermined period is less than the first predetermined period.
In this embodiment, when the terminal device determines that the acquired to-be-processed key value is smaller than the set key threshold, it indicates that the touch operation is currently performed. The terminal equipment acquires a certain number of key values at a frequency faster than the acquisition frequency of the key values to be processed, wherein the faster frequency is a second period; the certain number is the first preset number, so that the acquired key values of the first preset number form a key data set, subsequent comparison and judgment are facilitated, touch release is judged in time, and corresponding response is carried out. The second preset period can be set to 10ms, and the data sampling frequency can be improved by shortening the period, so that the result value is more accurate; the first predetermined number may be set to 10.
And S103, when all the key values in the key data set are smaller than the key threshold, calculating a first average value of all the key values in the key data set.
And step S104, determining a trigger result according to the first average value.
In this embodiment, if the terminal device determines that all the key values in the key data set are smaller than the key threshold, which indicates that the current state may still be in the touch state, the terminal device needs to further confirm the current state, that is, the terminal device calculates a first average value of all the key values in the touch key data set, and determines the trigger result according to the obtained first average value. Correspondingly, if a key value which is not smaller than the key threshold value exists in the key data set, the terminal device determines the current trigger result as touch release, that is, the current touch is finished, and the terminal device continues to acquire the key value to be processed at intervals of the first preset period and then performs discrimination.
In one embodiment, as shown in fig. 2, step S104 includes:
step S201, continuously obtaining the key values at intervals of a second preset period to obtain the latest key data set.
And S202, calculating a second average value of each key value in the latest key data set.
And S203, when the second average value is larger than the first average value, determining that the trigger result is touch release.
In this embodiment, the terminal device continues to obtain key values at intervals of a second preset period to form a latest key data set, the terminal device compares the average value, that is, a second average value, of each key value in the latest key data set with the first average value to determine, if the second average value is greater than the first average value, that is, the second average value indicates that the key value result representing the current time is greater than the key value that may be in the touch state at the beginning, the terminal device determines that the current trigger result is touch release, that is, the current touch is finished, and the terminal device continues to obtain key values to be processed at intervals of the first preset period to determine.
In one embodiment, as shown in fig. 3, step S201 includes:
step S301, at least one group of key values with a second preset number is obtained.
And step S302, carrying out average value processing on the second preset number of key values to obtain a key average value.
And step S303, replacing the key mean value with the key data set to obtain the key value with the earliest time, and obtaining the latest key data set.
In this embodiment, the terminal device obtains at least one group of second preset number of key values, performs averaging processing on the key values to obtain a key average value that can represent the time period, and replaces the key value with the earliest time in the key data set with the obtained key average value to obtain a latest key data set, so as to facilitate subsequent result determination.
As a specific example, but not limited to, it is set that {2, 3, 2, 4, 5} exists in the current key data set, the key values are arranged in the morning and evening of time, when two groups of key values of the second preset number are obtained, and after the two groups of key values of the second preset number are subjected to averaging processing, the key mean values 3 and 4 are obtained, then after the key mean values are replaced, the latest key data set is obtained as {3, 4, 2, 4, 5}.
In one embodiment, as shown in fig. 4, after step S202, the method includes:
and S401, when the second average value is smaller than or equal to the first average value, continuously acquiring key values at intervals of a second preset period to obtain a latest key data set.
Step S402, judging a third average value of each key value in the latest key data set until the third average value is larger than the first average value, and determining that the trigger result is touch release.
In this embodiment, if the terminal device determines that the second average value is smaller than or equal to the first average value, it indicates that the key value result representing the current time is smaller than the key value that may be in the touch state initially, the current trigger result of the terminal device is still a touch key, the terminal device continues to obtain key values at intervals of the second preset period, and obtains a latest key data set, and then determines a third average value and a first average value of each key value in the latest key data set until the third average value is greater than the first average value, that is, the key value result representing the current time is larger than the key value that may be in the touch state initially, which indicates that the current touch is ended, and the terminal device continues to obtain key values to be processed at intervals of the first preset period, and then determines.
In one embodiment, after step S203, comprising: and calculating the product of the second average value and a preset threshold value calculation coefficient, and setting the product as a key threshold value.
In this embodiment, when the terminal device determines that the current trigger result is touch release, that is, when the current touch is finished, the key threshold value compared with the key value needs to be updated, so as to accurately determine the subsequent state and perform a relevant response, therefore, the terminal device needs to set the product of the second average value and the preset threshold calculation coefficient as the key threshold value.
In the embodiment of the application, the key values to be processed are obtained at intervals of a first preset period, when the key values to be processed are smaller than a preset key threshold value, it is indicated that touch key operation is currently performed, then a first preset number of key values are obtained at intervals of a second preset period, a key data set is obtained, and then judgment after touch key generation is performed according to the obtained key data set, wherein the second preset period is smaller than the first preset period, and the judgment result after touch key generation is more accurate through the improvement of the key value obtaining frequency. When all the key values in the key data set are smaller than the key threshold, the current state is still in a key touch state, then a first mean value of all the key values in the key data set is calculated, and a trigger result is determined according to the first mean value so as to further determine the current state after the key is touched, thereby solving the problem that the current state is misjudged due to inaccuracy of a detection result after the key touch is finished.
In an embodiment, because some interference exists, the capacitance value sampled by the touch key is inaccurate, and the touch key is prone to causing slow response to the touch operation, the terminal device needs to determine a currently detected key value to determine whether the touch key occurs currently, therefore, the terminal device performs comparison determination by obtaining a currently obtained first key value and a last obtained second key value, when the terminal device determines that the first key value is smaller than the second key value, it indicates that the current key value is smaller, when the obtained key value is lower than a set key threshold, the touch operation occurs, and if the first key value is larger than the preset key threshold, it indicates that although the current first key value is smaller, it cannot be accurately determined whether the touch operation occurs, and possibly due to the influence of environmental factors, the first key value is smaller, so that a first difference value between the first key value and the key threshold and a second difference value between the second key value and the key threshold are obtained, and whether the trigger result of the touch key occurs currently is further determined according to the first difference value and the second difference value.
In an embodiment, the determining the trigger result according to the first difference and the second difference includes: and the terminal equipment compares the second difference with a first product and a first difference of a preset first comparison coefficient, if the first difference is larger than the first product, the fact that the reduction of the current touch value is possibly caused by factors such as external environment and the like is indicated, the triggering result is set to be without a touch key, and the terminal equipment continues to acquire a key value.
Correspondingly, if the first difference is smaller than or equal to the first product, it is indicated that the reduction of the current key values may be caused by the user touching the keys, and further judgment needs to be performed, so the terminal device obtains a second preset number of key values at intervals of a second preset period, sorts the second preset number of key values by size, selects a third preset number of key values located in the middle from the sorted second preset number of key values, and uses the mean value of the third preset number of key values as the latest judgment basis. Specifically, if the mean value is judged to be less than or equal to a second product of the second difference value and a preset second comparison coefficient, the reduction of the current touch value is that the user touches the key, and the triggering result is set as the touch key; if the mean value is greater than the second product, it indicates that the decrease of the current key values may be caused by factors such as external environment, and the like, the mean values of the fourth preset number need to be continuously obtained by the above method for obtaining the mean values of the key values of the third preset number, and if all the mean values of the fourth preset number are less than the first product, the trigger result is set as the touch key. The current trigger result, namely whether touch operation is currently carried out or not, is determined through the means, so that the problem that the touch key is not responded is solved. The key value is obtained by the terminal equipment every other first preset period; the third preset number may be set to 3; the fourth preset number may be set to 4; the first comparison coefficient may be set to 10%; the second comparison coefficient is larger than the first comparison coefficient, and the second comparison coefficient may be set to 20%.
In one embodiment, the terminal device may adjust a key threshold value compared with the key values to increase a success rate of response when the key is touched, so that the terminal device may obtain a first preset number of key values at intervals of a third preset period, and select a maximum value and a minimum value from the first preset number of key values; the terminal equipment can judge the current sampling environment according to the difference value of the maximum value and the minimum value in the acquired key values. The accuracy of the final result is low due to the unstable sampling environment, so that the product of the minimum value and the preset threshold value calculation coefficient needs to be calculated under the condition that the sampling environment is stable, namely the difference value between the maximum value and the minimum value is smaller than the product of the maximum value and the preset stability coefficient, so as to be convenient for comparing with the current key threshold value to judge whether touch operation is performed currently, if the product is larger than the preset key threshold value, the touch operation is not performed currently, and therefore in order to enable subsequent touch to successfully respond, the key threshold value needs to be corrected in time, and the key threshold value is closer to a reasonable range. Therefore, the product of the minimum value and the preset threshold calculation coefficient can be replaced by the key threshold, so that the key threshold is corrected, and the success rate of response when the key is touched is improved. Wherein the third predetermined period may be set to 300s; the preset stability factor can be set to 1%, and the stability interval can be enlarged by increasing the stability factor to adapt to the user requirement.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
