Detailed Description
In order to make the solution of the embodiment of the present invention better understood by those skilled in the art, the embodiment of the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
The embodiment of the invention provides a method and a device for error correction of key false touch, which effectively identify the condition that each key is triggered by false through pressing information when the key is triggered, so as to correct the error of the false-triggered key, improve the accuracy of error correction in the input process and improve the input quality of a user.
As shown in fig. 1, a flowchart of a key error touch correction method according to an embodiment of the present invention includes the following steps:
step 101, in the process of inputting by a user, obtaining the pressing information when each key is triggered.
When the key is triggered by mistake, because the user does not actively apply force to the key, the pressing force and/or the contact area of the key triggered by mistake are smaller than those of the normal key, so that in the embodiment of the invention, whether the key is actively triggered by the user or is triggered by mistake is judged by acquiring the pressing information of the key triggered by the key.
The pressing information may be pressure information or coverage area information, or both of these information may be included. Both the information can be used for obtaining pressure information and coverage area information acquired by the equipment sensor by calling an application program interface provided by the input application.
Step 102, determining the false triggering key according to the obtained pressing information.
Specifically, according to application requirements, there may be various judging methods:
for example, if the pressing value of the current key is smaller than the pressing values of the front and rear keys, determining that the current key is a false triggering key;
for another example, if the pressing value of the current key is smaller than the pressing values of other keys in the complete input, determining that the current key is a false triggering key.
The pressing value may be a pressure or a coverage area, and it is of course also possible to determine whether both of them satisfy the corresponding conditions.
And 103, correcting errors of the false triggering keys.
Because the false triggering key is not the key which the user wants to trigger, that is, the input of the corresponding key is not the target input of the user, when the false triggering key is corrected, the character which is input corresponding to the false triggering key can be deleted, and the character string which is input completely at one time after the correction is obtained.
And 104, determining each candidate word corresponding to the corrected complete input string.
It should be noted that the complete input string refers to all input characters composed of the current key and the triggered history key, for example, the input string that the user inputs completely at a time by using the pinyin input method is "qpinhan".
In addition, the input process of the user is continuous, and accordingly, each candidate word corresponding to the corrected complete input string is dynamically changed.
Further, in order to avoid erroneous deletion caused by erroneous judgment, in another embodiment of the method of the present invention, the score of the complete input string obtained before deleting the character corresponding to the false triggering key and after deleting the character corresponding to the false triggering key may be calculated, where the score may specifically be a ranking score in the input method; and taking the input string with higher score as the complete input string after error correction. Then, each candidate word corresponding to the corrected complete input string is determined.
The method provided by the embodiment of the invention can be applied to various input methods, is not only suitable for Chinese input realized by utilizing various input methods, but also suitable for English and other languages, and if the input is English, the finally output candidate word is an English word.
The following will illustrate the process of correcting errors by using the key error touch correction method provided by the embodiment of the invention in the pinyin input Chinese process.
Assuming that the user inputs qinhan (ash) but inputs q and mistakenly touches p, the result input string is qpinhan, since when the user mistakenly touches p, the key pressure is smaller than other keys of the input, namely the key q, i, n, h, a, n, and the key coverage area is also smaller than other keys of the input, namely the key q, i, n, h, a, n, the p is determined to be caused by mistakenly touching the key, the mistakenly touched key is corrected, the corresponding character p is deleted, the character string qinhan is obtained, and the corresponding candidate word 'ash' is output.
Therefore, by using the method provided by the embodiment of the invention, the influence of the mistaken touch of the key on the input of the user can be greatly reduced, so that the input experience of the user is improved.
As shown in fig. 2, another flowchart of a key error touch correction method according to an embodiment of the present invention includes the following steps:
step 201, in the process of inputting by the user, obtaining the pressing information when each key is triggered.
Step 202, determining normal pressing values of all keys according to the historical pressing information.
The historical press information refers to press information of each key normally triggered by each user input, the press information can be press strength and/or contact area, and the information can be obtained through an application program interface provided by an input application.
In practical application, the above information may be directly recorded, and in order to avoid excessive occupation of memory resources, after a certain amount of corresponding pressing information is accumulated, the normal pressing value of each key may be calculated and stored, and the recorded historical pressing information may be deleted. In the subsequent user input process, the normal pressing value is dynamically updated, for example, the normal pressing value can be updated after the pressing information of each key is accumulated to a certain amount, or the normal pressing value after each key is input once is updated, and the updated normal pressing value is the average value of the historical pressing value and the current pressing value.
And 203, determining false triggering keys according to the obtained pressing information and the normal pressing values of the keys.
For example, if the pressing value of the current key is smaller than the normal pressing value of the key, determining that the current key is a false triggering key;
for another example, if the pressing value of the current key is smaller than the normal pressing value of the key and the pressing value of the current key is smaller than the pressing values of other keys in the complete input, determining that the current key is a false triggering key.
The pressing value may be a pressure or a coverage area, and it is of course also possible to determine whether both of them satisfy the corresponding conditions.
Step 204, record the historical press information of the non-false trigger key.
Step 205, error correction is performed on the false triggering key.
Step 206, determining each candidate word corresponding to the corrected complete input string.
Continuing with the above pinyin input example, assuming that the user inputs qinhan (qinhan), but inputs q and mistakenly touches p, the result input string is qpinhan, since when the user mistakenly touches p, the key pressure is smaller than the other keys of the input, namely, the key q, i, n, h, a, n, and the pressure of the user normally pressing p in the previous input, and the key coverage area is also smaller than the coverage area of the other keys of the input, namely, the key q, i, n, h, a, n, and the coverage area of the user normally pressing p in the previous input, it is determined that p is caused by mistaken touch of the key, the mistaken touch key is corrected, the corresponding character p is deleted, the character string qinhan is obtained, and the corresponding candidate word "qinhan" is output.
According to the key false touch error correction method, when a user inputs, the false trigger key is determined based on the pressing information of each key in the current input and the historical pressing information of each key, or the historical pressing information of each key is referred to at the same time, the pressing information of the current key in the current input is compared with the pressing information of other keys in the complete input, and the false trigger key is determined, so that the accuracy of judging the false trigger key can be further improved, the influence of false touch on the user input is reduced, and the input experience of the user is improved.
In addition, because the keyboard layout, the input environment and the like of the user equipment are different, the probability of false triggering of each key is also different, and therefore, in another embodiment of the method of the invention, the false triggering weight of each key can be determined according to the position and/or the current input environment of the key; the current input environment includes, but is not limited to: a current input device type, a current input device state; the input device type such as: notebook, computer, PAD, cell phone, etc., the input device state refers to whether the input device is currently in a stationary state or in a moving state.
The obtained pressing value of the corresponding key is adjusted by utilizing the false triggering weight value, so that the accuracy of the subsequent false triggering key judgment is improved; for example, for a key on a mobile phone, the closer to the edge of the screen, the higher the probability of being triggered by mistake; for a key that is activated in a moving state, the probability of being activated by mistake is relatively high relative to a key that is activated in a stationary state. The higher the false triggering probability is, the smaller the false triggering weight is.
For example, the false triggering weight can be calculated by the following formula:
wherein,represent the firstiFalse triggering weight of each key, +.>Represent the firstiThe shortest distance of each key from the edge of the screen,representing the shortest distance between the center of the keyboard and the edge of the screen,/the keyboard>Represent the firstiSpeed of the input device when the keys are activated, < >>And->Is a weighting coefficient.
It should be noted that, the embodiment of the present invention is not limited by the specific calculation formula of the false triggering weight, and the same effect can be achieved by adjusting the obtained pressing value of the corresponding key based on the above principle, that is, the accuracy of the false triggering key judgment is improved.
Correspondingly, when the false triggering key is determined, the obtained pressing value of the key can be adjusted according to the false triggering weight of each key, and then whether the key is the false triggering key is determined according to the adjusted pressing value, so that the method of the embodiment of the invention can be better suitable for various different input environments and keyboard layouts.
Correspondingly, the embodiment of the invention also provides a key false touch error correction device, which can be integrated in user equipment, wherein the user equipment can be a notebook, a computer, a PAD, a mobile phone and the like. When the user performs input operation, the user needs to press or touch corresponding keys in a keyboard of the user equipment, wherein the keyboard can be an entity keyboard or a virtual keyboard on a touch screen of the user equipment.
Fig. 3 and fig. 4 show an example of an input method not applying the method of the present invention and an actual screen display of the input method applying the method of the present invention, respectively, after the user inputs qinhan by touching the key p by mistake and actually inputting qpinhan.
By comparing the outputs of the examples of fig. 3 and fig. 4, it is obvious that by using the method of the present invention, the output error caused by the error of the key touch in the input process can be effectively corrected, and the input quality of the user can be improved.
Fig. 5 is a schematic structural diagram of a device for error correction of key touch according to an embodiment of the present invention.
In this embodiment, the apparatus comprises: an information acquisition module 301, a judgment module 302, an error correction module 303, and an output module 304. Wherein:
the information obtaining module 301 is configured to obtain, during a user input process, pressing information when each key is triggered. Specifically, when the user performs an input operation, the key is actively triggered by the user or is triggered by mistake, the information obtaining module 301 may obtain, through interaction with the user device, pressing information of the currently triggered key from an application program interface provided by the user device, where the pressing information may be collected by a corresponding sensor in the user device. As to how the user equipment obtains the corresponding values by using the corresponding sensors, the embodiment of the present invention is not limited.
In an embodiment of the present invention, the compression information may be pressure information and/or coverage area information. The pressure and the coverage area refer to the pressure and the coverage area applied to the current single key.
The judging module 302 is configured to determine that the key is triggered by mistake according to the obtained pressing information.
The error correction module 303 is configured to correct errors of the false triggering key. Since the false triggering key is not the key that the user wants to trigger, when the error correction module 303 corrects the false triggering key, the character input corresponding to the false triggering key can be directly deleted, so as to obtain the corrected complete input string. In addition, in order to avoid erroneous deletion caused by erroneous judgment, the error correction module 303 may calculate the score of the complete input string obtained before deleting the character corresponding to the false trigger key and after deleting the character corresponding to the false trigger key, and then use the input string with higher score as the complete input string after error correction.
In this embodiment, the compression information may be pressure information and/or coverage area information. Accordingly, the determination module 302 may also determine the false trigger key in a variety of ways. For example, when the pressing value of the current key is smaller than the pressing values of the front and rear keys, determining that the current key is a false triggering key; or when the pressing value of the current key is smaller than the pressing values of other keys in the complete input, determining that the current key is a false triggering key. Wherein the pressing value refers to a specific pressure and/or coverage area.
It should be noted that, the determination manner of the false triggering key by the determining module 302 according to the obtained pressing information is merely an example, and in practical application, other determination manners are also possible, as long as the false triggering key is determined according to the pressing information and is included in the protection scope of the present invention.
The key false touch error correction device provided by the embodiment of the invention can be applied to various input methods, is not only suitable for Chinese input realized by utilizing various input methods, but also suitable for English and other languages, and if the input is English, the finally output candidate word is the English word.
By using the key false touch error correction device provided by the embodiment of the invention, the influence of key false touch on user input can be greatly reduced, so that the input experience of a user is improved.
Fig. 6 is a schematic diagram of another structure of a device for error correction of touch by a key according to an embodiment of the invention.
In this embodiment, the apparatus comprises: an information acquisition module 301, a judgment module 302, an error correction module 303, an output module 304, a recording module 305, and a calculation module 306. Wherein:
the information obtaining module 301 is configured to obtain, during a user input process, pressing information when each key is triggered. Specifically, the pressing information of the currently triggered key may be obtained from an application program interface provided by the user equipment, where the pressing information may be: pressure information and/or coverage area information, both of which refer to the pressure and coverage area applied to the current single key.
The judging module 302 is configured to determine that the key is triggered by mistake according to the obtained pressing information.
The error correction module 303 is configured to correct errors of the false triggering key. Since the false triggering key is not the key that the user wants to trigger, when the error correction module 303 corrects the false triggering key, the character input corresponding to the false triggering key can be directly deleted, so as to obtain the character string input completely once after error correction. In addition, in order to avoid erroneous deletion caused by erroneous judgment, the error correction module 303 may calculate the scores of the character strings that are input once and are obtained before and after deleting the character corresponding to the false trigger button, and then use the character string with the higher score as the character string that is input once and is input once after error correction.
The output module 304 is configured to determine each candidate word that is completely input after error correction, that is, determine each candidate word corresponding to the character string that is completely input after error correction.
The recording module 305 is configured to record historical press information of a non-false triggering key in the input process.
The calculating module 306 is configured to determine a normal pressing value of each key according to the historical pressing information.
It should be noted that, the recording module 305 may directly record the pressing information of the non-false triggering key in each input process, so as to avoid the overflow of the stored data due to the limitation of the storage space, and delete the historical data with earlier time after the corresponding pressing information is accumulated to a certain amount, and so on, that is, the recorded pressing information of the non-false triggering key is continuously updated. Of course, after the corresponding pressing information is accumulated to a certain amount, the normal pressing value of each key may be calculated and stored. The normal press value is dynamically updated during each subsequent user input.
Accordingly, in this embodiment, the judging module 302 may determine the false triggering key based on the pressing information of the current key and the historical pressing information, and the specific judging manner may also be various, for example: when the pressing value of the current key is smaller than the normal pressing value of the key, determining that the current key is a false triggering key; or when the pressing value of the current key is smaller than the normal pressing value of the key and the pressing value of the current key is smaller than the pressing values of other keys in the complete input, determining that the current key is a false triggering key.
Likewise, the determination mode of the false triggering key by the determining module 302 according to the obtained pressing information and the historical pressing information is merely an example, and in practical application, other determination modes are also possible, as long as the false triggering key is determined to be included in the protection scope of the present invention according to the pressing information.
