[0028] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0029] The method for confirming a reported point provided by the embodiment of the present disclosure is applied to confirming a reported point by an electronic device.

[0030] With the rapid development of science and technology, more and more electronic devices can provide touch screen functions. People can issue control instructions to electronic devices with touch screens through a variety of touch screen tools. Common touch screen tools include fingers, styluses, etc.

[0031] As we all know, when using a touch screen tool to issue a control command to an electronic device with a touch screen, contact is generated with the screen. In fact, part of the contact area is the actual effective area, which will be regarded as the reporting area or target area by the device. Generally speaking, using common touch screen tools to touch the screen will generate reporting points, but there are exceptions. Whether a reporting point can be generated depends on the state of the touch object touching the screen.

[0032] For example, when a stylus pen is used to touch the screen, if the angle between the stylus pen and the screen is very small, only the insulating part of the edge of the stylus pen contacts the screen, and no point is reported; similarly, if a fingernail touches the screen, no point is reported. Therefore, the present disclosure refers to structures such as the edge of a stylus pen and a fingernail that are attached to the touch object but do not produce a point when touching the touch screen as associated parts.

[0033] In the related art, when a user uses a mobile device to type, for a user who is accustomed to using a 26-key input method layout, when the thumb is pressed, the overly long thumb nail will press against the screen, causing the pressing area to shift, resulting in the user being unable to obtain a good typing experience.

[0034] Not only that, in most other cases where commands are input through fixed buttons, the associated parts can easily cause the reporting points to shift during the touch screen process.

[0035] In view of this, an embodiment of the present disclosure provides a method for confirming a reporting point, which identifies a touch object and an associated part, determines a target area and an offset, and can correct the reporting point position according to a preset corresponding relationship when the reporting point may be offset.

[0036] Figure 1 is a flow chart of a method for determining a reporting point according to an exemplary embodiment. Figure 1 As shown, the reporting point determination method is used in a terminal and includes the following steps.

[0037] In step S11, in response to the touch screen of the electronic device detecting contact of an associated portion of a touch object, a first target area contacted by an unassociated portion of the touch object is determined.

[0038] In the embodiment of the present disclosure, the touch object refers to a subject that touches the touch screen of an electronic device, such as a finger.

[0039] In the embodiment of the present disclosure, the associated part refers to an object that the touch object contacts the screen but does not generate a point report, such as a fingernail.

[0040] In the disclosed embodiment, when a touch object touches the touch screen, the reporting point generated by the touch may be affected by the associated part. For example, the associated part may cause the posture of the touch object to change when touching the touch screen due to the volume it occupies, thereby affecting the reporting point position.

[0041] In the embodiment of the present disclosure, the target area refers to a partial area in the display area of ​​the touched touch screen, that is, there may be multiple target areas for the same display touch screen.

[0042] In the disclosed embodiment, the reporting point offset refers to the difference between the reporting point recognized by the device and the reporting point of the touched object without being affected by the associated part. In the disclosed embodiment, there is a certain correspondence between the target area and the reporting point offset, and the correspondence indicates that the reporting point offset is affected by the target area.

[0043] In the disclosed embodiment, after the target area is acquired, it is necessary to confirm the actual reporting point position, that is, it is necessary to acquire the offset of each target area.

[0044] In step S12, based on the correspondence between the target area and the reporting point offset, a first offset corresponding to the first target area is determined.

[0045] In the disclosed embodiment, since there is a corresponding relationship between the target area and the reporting point offset, the offset corresponding to each target area can be determined by the acquired target area.

[0046] In the disclosed embodiment, after the offset is obtained, the actual reporting point corresponding to the first target area can be determined according to the obtained offset.

[0047] In step S13, the first target area is corrected based on the first offset to obtain a second target area.

[0048] In the disclosed embodiment, the second target area is the area after the first target area is corrected, that is, the second target area is obtained by the first target area and the first offset corresponding to the first target area; since the first target area and the first offset are known, the second target area can be calculated based on the first target area and the first offset.

[0049] In the disclosed embodiment, after the second target area is acquired, the position of the reporting point needs to be determined.

[0050] In step S14, the second target area is determined as the reporting point area.

[0051] In the disclosed embodiment, since the second target area is the area obtained after correction, the second target area is used as the reporting point area.

[0052] Using the second target area as the reporting area can effectively improve the quality of reporting and increase the accuracy of reporting.

[0053] In the embodiment of the present disclosure, in the process of determining the second target area, the relationship between the first target area and the first offset needs to be determined in advance, that is, for all target areas, the relationship between the target area and its corresponding offset needs to be determined.

[0054] Figure 2 is a flow chart showing a method for determining a corresponding relationship between a target area and an offset according to an exemplary embodiment. Figure 2 As shown, the method for determining the correspondence between the target area and the offset is used in a terminal, and includes the following steps.

[0055] In step S21, the touch object including the associated part touches the target area N times, and the average value of the reported point coordinates corresponding to the N times is determined as the first reported point coordinates.

[0056] In the disclosed embodiment, the first reporting point coordinates refer to the reporting point coordinates triggered when the peripheral area of ​​the touch object touches the target area and also contacts the touch screen.

[0057] In the disclosed embodiment, when obtaining the first reported point coordinates, the value of N can be as large as possible so that the obtained mean can be closer to the actual situation. Therefore, the accuracy of the finally obtained mean of the reported point coordinates can be guaranteed, and the mean is used as the first reported point coordinates.

[0058] In the embodiment of the present disclosure, after obtaining the reporting point affected by the associated part, in order to obtain the offset, the reporting point position when the touch object is not affected by the associated part is required.

[0059] In step S22, the touch object without the associated part touches the target area N times, and the average value of the reported point coordinates corresponding to the N times is determined as the second reported point coordinates.

[0060] In the embodiment of the present disclosure, the second reporting point coordinates refer to the reporting point coordinates triggered when the touch object touches the target area but the peripheral area does not contact the touch screen, that is, the reporting point actually desired to be corrected.

[0061] In the disclosed embodiment, when obtaining the second reported point coordinates, the value of N should be as large as possible so that the obtained mean can be closer to the actual situation. Therefore, the accuracy of the finally obtained mean of the reported point coordinates can be guaranteed, and the mean is used as the second reported point coordinates.

[0062] In the embodiment of the present disclosure, after obtaining the average reported point of the touch object in the target area under the influence of the associated part and the average reported point of the touch object without being affected by the associated part, the offset can be calculated.

[0063] In step S23, the difference between the first reporting point coordinates and the second reporting point coordinates is determined, and the difference is used as the reporting point offset.

[0064] In the disclosed embodiment, the difference between the first reported point coordinates and the second reported point coordinates is not limited to the numerical value, but also includes the direction of the offset.

[0065] In the embodiment of the present disclosure, the offset of a target area can be obtained, so for multiple target areas, the offset corresponding to each target area can also be obtained. Therefore, the reporting point offsets of all target areas can be obtained by this method.

[0066] In step S24, a correspondence between the target area and the reporting point offset is created.

[0067] In the disclosed embodiment, since the reporting point offsets corresponding to all target areas can be obtained, the corresponding relationship between the target area and the reporting point offset can be created through each target area and its corresponding reporting point offset. For example, for target area a, the reporting point offset that best fits the actual situation for the target area a can be obtained through multiple reporting points, and it is saved in the created corresponding relationship between the target area and the reporting point offset. The corresponding relationship can be called at any time in subsequent operations involving the target area a.

[0068] After obtaining the corresponding relationship between the target area and the reporting point offset, the subsequent reporting point correction operation can be made more convenient and quick.

[0069] In the embodiment of the present disclosure, after the corresponding relationship between the target area and the reporting point offset is created, the reporting point can be corrected using the corresponding relationship. Figure 3 is a flow chart of a method for correcting a reporting point according to an exemplary embodiment. Figure 3 As shown, the reporting point correction method is used in a terminal and includes the following steps.

[0070] In step S31, the positive or negative value of the reporting point offset value is determined.

[0071] In the disclosed embodiment, for a certain target area, the corrected reporting point may be in various directions of the target area, so the reporting point offset has positive and negative values, and the positive and negative signs are used to characterize the direction of the offset.

[0072] In the embodiment of the present disclosure, in order to determine the direction of the offset, it is necessary to judge whether the reporting point offset is positive or negative.

[0073] In the disclosed embodiment, after determining the positive or negative sign of the reporting point offset value, it is necessary to determine the direction and position of the correction according to the positive or negative sign.

[0074] In step S32, if the reporting point offset is a positive value, the first target area is shifted in the first offset direction by a value corresponding to the reporting point offset, and is determined as the second target area.

[0075] In the embodiment of the present disclosure, the first offset direction refers to the offset direction corresponding to a positive offset.

[0076] In the embodiment of the present disclosure, when the reporting point offset is a positive value, the first target area is offset in the first offset direction, and the offset value is the absolute value of the offset. For example, when the first offset direction is set to the right in the horizontal direction, if the reporting point offset corresponding to the first target area is +3, the first target area is used as the basis, and the area is moved to the right by 3 unit lengths in the horizontal direction, and the obtained area is determined as the second target area.

[0077] In step S33, if the reporting point offset is a negative value, the first target area is shifted in the second offset direction by a value corresponding to the reporting point offset, and is determined as the second target area.

[0078] In the embodiment of the present disclosure, when the reporting point offset is a negative value, the first target area is offset in the second offset direction, and the offset value is the absolute value of the offset. For example, when the second offset direction is set to the horizontal left, if the reporting point offset corresponding to the first target area is -3, the first target area is used as the basis, and the area is moved 3 units to the left in the horizontal direction, and the obtained area is determined as the second target area.

[0079] It should be understood that, in the embodiment of the present disclosure, the first offset direction and the second offset direction corresponding to the positive and negative offsets of the reporting points on the same horizontal line are in opposite directions.

[0080] In the embodiments of the present disclosure, the offset direction may be in any direction, and the present disclosure does not limit this.

[0081] After determining how to obtain the second target area according to the offset, the operation of correction according to the target area reporting point and the offset corresponding to the target area is implemented.

[0082] In the disclosed embodiment, although the reporting point correction operation can be implemented, before the reporting point position correction of the target area is performed, it is necessary to determine whether the current scene meets the reporting point correction conditions.

[0083] Figure 4 is a flow chart of a touch position determination method according to an exemplary embodiment. Figure 4 As shown, the touch position determination method is used in a terminal and includes the following steps.

[0084] In step S41, in response to detecting that a touch area exists on the touch screen of the electronic device, a capacitance change amount of the touch area is determined.

[0085] In the disclosed embodiment, the electronic device touch screen can detect the capacitance change when the touch object contacts the touch screen. For example, when the user touches the screen with a finger and a nail, the capacitance of the screen will change differently.

[0086] In the embodiment of the present disclosure, after the sum of the capacitance changes of the touched areas is determined, it is also necessary to compare the capacitance change with the capacitance change preset in advance.

[0087] In step S42, it is determined whether the capacitance change amount matches a preset capacitance change value.

[0088] In the embodiment of the present disclosure, the preset capacitance change value is a capacitance change amount generated when the touch object and the associated part are in contact with the touch screen of the electronic device, which is measured in advance.

[0089] In the disclosed embodiment, the matching of the capacitance change with the preset capacitance change value means that the capacitance change value at each point in the target area is equal to the preset capacitance change value at each point.

[0090] In step S43, it is determined that the associated portion of the touch object contacts the touch screen of the electronic device.

[0091] In the disclosed embodiment, after detecting that the capacitance change amount matches the preset capacitance change value, it is considered that the current scenario satisfies that the associated part of the touch object contacts the touch screen of the electronic device.

[0092] In the disclosed embodiment, the touch object may be a finger, the associated part of the touch object may be a nail, and the target area may be a keyboard area on the input method virtual keyboard. For example, when a finger with a nail touches the virtual keyboard, the nail may cause the position of the finger touching the screen to shift, so a correction operation needs to be performed on the reporting point. The reporting point obtained after correction is consistent with the reporting point of the finger on the virtual keyboard when it is not affected by the nail, thereby reducing the probability of the user making a wrong typing due to the nail, thereby improving the user experience.

[0093] In the disclosed embodiment, the method for correcting the reporting point can be used in the user's typing scenario, and can be used to optimize the touch screen reporting point position when the user has long nails, for example, to optimize the touch reporting point position of the 26-key input method.

[0094] In the embodiment of the present disclosure, data collection is required when determining the offset. To be practical, the coordinates of the 26-key reporting points can be collected manually. Since the thumb is the most commonly used tool when typing, the thumb can be used to collect data on the reporting point position.

[0095] In the embodiment of the present disclosure, during the acquisition process, when the real thumbnail can touch the screen, use the thumb to click each key on the keyboard, during which the fingernail is guaranteed to touch the screen, and the report point obtained by the click is recorded. Each report point is repeated 10 times, and the report point coordinates report_1_i (x j ,y j ). Integrate the 10 collected report points and take the average value to get the actual report point report_1_i(x,y) of the ith key when the user's fingernail touches the screen. Repeat the above method to get the actual report point of each area on the 26-key keyboard when the user's fingernail touches the screen when typing.

[0096] In the disclosed embodiment, if the user's nails are too short to touch the screen when typing, the user can put false nails on the thumb that can touch the screen, and then complete the data collection operation according to the above-mentioned collection method when the user's nails can touch the screen.

[0097] In the disclosed embodiment, after obtaining the reporting point of each key when the user's fingernails touch the screen while typing, it is also necessary to obtain the reporting point of each key when the user is not affected by the fingernails.

[0098] In the disclosed embodiment, the user can collect data again in a way that the fingernails cannot touch the screen, or can collect data by cutting the fingernails short so that they cannot touch the screen. For example, use the thumb to click each key on the keyboard, during which the fingernails are guaranteed to touch the screen, and enter the report point obtained by the click. Each report point is repeated 10 times, and the report point coordinates report_2_i (x j ,y j ). The 10 collected report positions are integrated and averaged to obtain the average report position report_2_i(x,y) when the user's fingernail does not touch the screen.

[0099] Through the above data collection, the accurate reporting point of each key on the keyboard can be obtained when the user's nail touches the screen and when the nail does not touch the screen.

[0100] In the disclosed embodiment, after the data collection work is completed, an offset table can be established based on the collected data to indicate the offset of each key.

[0101] In the disclosed embodiment, the offset of each key is obtained by subtracting the average value of the points reported when the user's nail touches the screen from the average value of the points reported when the user's nail does not touch the screen.

[0102] In the embodiment of the present disclosure, the offset of the i-th key is defined as Δdiff i (Δx, Δy), specify Δdiff i (Δx, Δy) = report_2_i(x, y) - report_1_i(x, y); where report_2_i(x, y) - report_1_i(x, y) represents the difference between the reported point when the user's nail does not touch the screen and the reported point when the user's nail touches the screen for the i-th key.

[0103] In the disclosed embodiment, the offset Δdiff of the i-th key i (Δx, Δy) contains two parameters for indicating the offset, Δx and Δy. Since the offset may be in various directions, for ease of operation, Δx is defined as the offset in the horizontal direction on the plane where the touch screen is located, with positive values ​​to the right; for example, Δx=3 means that the offset is 3 units in the horizontal direction to the right. Δy is defined as the offset in the vertical direction on the plane where the touch screen is located, with positive values ​​to the upward direction; for example, Δy=-3 means that the offset is 3 units in the vertical direction downward. By defining the direction, Δdiff can be used. i (Δx, Δy) represents any offset on the plane where the touch screen is located.

[0104] In the embodiment of the present disclosure, when establishing the offset table for point reporting correction, in order to facilitate processing, the offset Δdiff of the i-th key needs to be i (Δx, Δy) is further converted into the form of direction and absolute offset and its direction is recorded. The absolute offset of the i-th key is expressed in the form of |Δx| and |Δy|. The direction and absolute offset are recorded in the offset table and stored in the device. For example, if the Δdiff corresponding to the i-th key is i In (Δx, Δy), Δx=3, Δy=-3. The offset data recorded in the table should be: 3 unit lengths to the right in the horizontal direction and 3 unit lengths downward in the vertical direction.

[0105] To facilitate understanding of offset determination, Figure 5 is a diagram showing an example of determining an offset according to an exemplary embodiment.

[0106] like Figure 5As shown in the figure, area 1 represents fingers and area 2 represents nails. A, B, and C represent the three keys on the numeric keypad respectively. Point M is the reporting point when the user's nails touch the screen, and point N is the reporting point when the user has no nails or the nails are cut short and do not touch the screen. The straight line OM is the straight line in the horizontal direction of the plane where the keyboard is located, and the straight line ON is the straight line in the vertical direction of the plane where the keyboard is located. The angle between the straight line OM and the straight line ON is a right angle, and the length of OM is Δx and the length of ON is Δy.

[0107] In the disclosed embodiment, the user originally wants to touch key A, but the fingernail hits the screen, causing the reporting point to shift, and the actual reporting point is point M. If the user is not affected by the fingernail, he will press point N. Therefore, for key A, the offset is the offset from point N to point M. Therefore, for key A, the reporting point when the fingernail touches the screen is offset by a length of |Δx| to the right in the horizontal direction and a length of |Δy| to the downward in the vertical direction based on the reporting point when the fingernail does not touch the screen.

[0108] By determining the offset, the relationship between the reported points when the fingernail touches the screen and the reported points when the fingernail does not touch the screen becomes clear.

[0109] In the disclosed embodiment, by sequentially entering the offset of each key, the offset table of all keys can be established.

[0110] In the disclosed embodiment, after the offset table is established, the offset table can be used to correct the reporting point.

[0111] In the disclosed embodiment, when performing the reporting point correction operation, it is necessary to first detect whether the fingernail touches the screen; only when it is detected that the fingernail touches the screen, the subsequent correction operation is performed.

[0112] In the disclosed embodiment, the detection of the fingernail touching the screen is determined by the change in capacitance of the touch screen when the touch screen is touched.

[0113] In the disclosed embodiment, the capacitance change of the touch screen area when the user's fingernails and fingers touch the screen at the same time is preset in the terminal in advance. Since the capacitance change of the screen when the fingernails and fingers touch the screen are different, only when the user's fingernails and nails touch the screen at the same time when touching the screen, the capacitance change of the touch area will be the same as the capacitance change of the touch area when the user's fingernails and fingers touch the screen at the same time preset in the terminal. Therefore, this method can accurately identify whether the user's fingernails touch the screen when using fingers to touch the screen.

[0114] In the embodiment of the present disclosure, when it is confirmed that the user's finger and nail touch the screen at the same time, a correction operation will be performed on the reporting point at this time according to the offset table.

[0115] In the embodiment of the present disclosure, when performing the report point correction operation, if the key currently clicked by the user is the i-th key on the keyboard, the report point obtained in this case is recorded as report_i(x, y). This report point is the report point when the fingernail touches the screen, so the corresponding report point can be found in the offset table established in advance. According to the corresponding relationship in the table, the current report point plus the offset Δdiff obtained by looking up the table is i (Δx, Δy), the corrected reporting point can be obtained.

[0116] In the embodiment of the present disclosure, the correction report point is based on report_c_i(x,y)=report_i(x,y)+Δdiff i (Δx, Δy). Among them, report_c_i(x, y) is the corrected reporting point in the current scene, report_i(x, y) is the actual reporting point where the fingernail touches the screen in the current scene, and Δdiff i (Δx, Δy) represents the offset of the i-th key in the offset table. Through the above calculation, the corrected report_c_i(x,y) can be obtained when the user's fingernail hits the screen and the report for the i-th key is report_i(x,y). The corrected report is used as the command input terminal, which avoids the user's fingernail hitting the screen and causing the report to deviate, and the user cannot click the area they want to click, greatly improving the user's typing experience.

[0117] In the embodiments of the present disclosure, the user may touch the screen with both the fingernails and fingers at the same time when using other applications. At this time, the user may not need to perform typing operations, nor need to correct the reporting point. Therefore, the reporting point confirmation method in the present disclosure can be set to be executed only when the user is in a typing scenario, which can prevent the user from performing reporting point correction in a non-typing scenario, resulting in the user being unable to press the area he wants to press.

[0118] Based on the same concept, the embodiment of the present disclosure also provides a time reporting and confirmation device.

[0119] It is understandable that, in order to realize the above functions, the reporting point confirmation device provided by the embodiment of the present disclosure includes hardware structures and / or software modules corresponding to the execution of each function. In combination with the units and algorithm steps of each example disclosed in the embodiment of the present disclosure, the embodiment of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the technical solution of the embodiment of the present disclosure.
