Specifically, the input unit 130 may include a touch panel 131 and other input devices 132. The touch panel 131, also referred to as a touch screen, may collect touch operations of a user on or near the touch panel 131 (e.g., operations of the user on or near the touch panel 131 using any suitable object or accessory such as a finger or a stylus pen), and drive the corresponding connection device according to a preset program. Alternatively, the touch panel 131 may include two parts, i.e., a touch detection device and a touch controller.

Fig. 2 is a schematic flow chart of a false touch prevention method according to an embodiment of the present disclosure. As shown in fig. 2, the method for preventing false touch may be applied to an electronic device, and the method may include:
step 101: acquiring current contact data of a user on a touch panel of the electronic equipment.
It should be noted that, when a user holds the electronic device, the user mainly holds the electronic device by touching a side area of the electronic device, and when the user holds the electronic device, the user may touch a side area of a touch panel, that is, a touch screen. For example, if the sensing unit array is a capacitance sensing matrix, when a user holds the electronic device, the sensing value of the capacitance sensing matrix changes, and the current touch data is obtained by obtaining the sensing value of the current capacitance sensing matrix.
Step 102: inputting the current contact data into a trained recognition model to obtain a suppression area corresponding to the current contact data, wherein the trained recognition model is obtained by training a preset recognition model through holding posture data and touch operation data generated by a user under various holding postures, the holding posture data is used for indicating contact data generated by the contact between a holding part of the user and the touch panel, and the touch operation data is used for indicating contact data generated by the touch operation of an operation part of the user on the touch panel.
It should be noted that the electronic device is provided with a trained recognition model, the obtained current contact data is input into the trained recognition model, and the trained recognition model can output a corresponding inhibition area, that is, information of the inhibition area on the touch panel, which needs to be prevented from being touched by mistake, is generated according to the contact data of the user.
The trained recognition model is obtained through training or correction, a preset recognition model capable of generating a suppression area according to contact data is preset in the electronic device before delivery, but the preset recognition model is obtained through training based on big data operated by a user, the size of a hand of each user, the thickness of fingers and other parameters are different, so that a recognition error may exist in the preset recognition model for the current user, and therefore the trained recognition model can be obtained through collecting personal contact data generated by the current user under various holding postures and training or correcting the preset recognition model through the personal contact data, and the accuracy of model recognition is improved.
The electronic device comprises a touch panel, a holding part, a holding gesture data acquisition module, a touch operation data acquisition module, a recognition model training module and a recognition model training module, wherein the holding gesture data acquisition module is used for acquiring holding gesture data and touch operation data generated by a user under various holding gestures to train a preset recognition model, the holding gesture data can comprise contact data generated by the contact of the holding part of the user and the touch panel, and the touch operation data can comprise contact data generated by the touch operation of the operating part of the user on the touch panel. For example, when a user holds the electronic device with a left hand, the user can use the thumb or other fingers of the left hand to perform touch control operation on the screen, and can use any finger of the right hand to perform touch control operation on the screen. The preset recognition model is trained or corrected through collecting the holding gesture data and the touch operation data, the trained recognition model is obtained, and the accuracy of model recognition can be improved.
Step 103: and executing a first operation on the inhibition area corresponding to the current contact data, wherein the first operation is used for controlling the touch sensitivity of the inhibition area corresponding to the current contact data to be less than or equal to a sensitivity threshold.
It should be noted that the touch function of the touch panel may be divided into a plurality of independently controllable sub-areas according to a preset unit area, and after determining a suppression area corresponding to current contact data, the touch sensitivity of the sub-area corresponding to the suppression area corresponding to the current contact data is adjusted, so that the touch sensitivity of the sub-area corresponding to the suppression area corresponding to the current contact data is set to be less than or equal to a preset sensitivity threshold; or after the suppression area corresponding to the current contact data is determined, the touch function of the sub-area corresponding to the suppression area corresponding to the current contact data may be turned off, that is, the touch sensitivity of the suppression area corresponding to the current contact data is reduced to 0, so that after the touch sensitivity of the suppression area is reduced, when the user touches the suppression area, corresponding touch response may not be performed, and thus, false triggering after the user touches is avoided.
In some embodiments, the starting modes for collecting the holding posture data and the touch operation data generated by the user under various holding postures are more, for example, the holding posture data and the touch operation data can be collected according to the user requirement, and when the user feels that the current suppression area is not accurate, the user can click through a menu of the electronic device to enter a data collection process; or when the user starts for the first time or enters the false touch prevention mode, the system automatically starts a data acquisition process; the data can be automatically collected when the user uses the false touch prevention function at ordinary times; the starting mode for collecting the holding gesture data and the touch operation data generated by the user under various holding gestures is not limited.
In this embodiment, the electronic device can collect holding posture data and touch operation data generated by the user in various holding postures when the user-defined false touch prevention switch is turned on, the false touch prevention function is turned on, or the false touch prevention function is entered.
Fig. 3 is a schematic flow chart of a false touch prevention method provided in an embodiment of the present application, as shown in fig. 3, on the basis of the embodiment shown in fig. 2, before step 101, the method may further include:
step 201: and outputting prompt information, wherein the prompt information is used for indicating a holding gesture of the electronic equipment held by a user and touch operation performed by the user in the holding gesture.

It can be understood that the schematic diagram of the above-mentioned prompt information is not used to limit the holding manner that needs to be collected, and in an actual application scenario, it may be determined according to needs which holding gesture data and touch operation data corresponding to the holding gesture + touch operation are collected. In addition, the touch panel collects the holding gesture data and the touch operation data in millimeter level, that is to say, the data collected by holding, clicking, sliding and the like are discrete characteristic data.
After the holding posture data and the touch operation data generated under various holding postures are obtained, the information needing to be obtained is a suppression area, so that the preset recognition model can be trained after the collected data are processed.
In some embodiments, in order to improve the accuracy of the training model, when acquiring the holding posture data corresponding to the user holding in the holding posture and the touch operation data corresponding to the user performing the touch operation, the detected data may be acquired after verification, that is, only valid data is acquired, and invalid data is discarded.
In this embodiment, the acquiring, in step 202, holding gesture data corresponding to the user holding the electronic device with the holding gesture and touch operation data corresponding to the user performing the touch operation may include:
step 2021: detecting holding gesture data corresponding to the fact that the user holds the electronic equipment in the holding gesture and touch operation data corresponding to the fact that the user performs the touch operation;
step 2022: determining whether the holding gesture adopted by the user is matched with the holding gesture indicated by the prompt information according to the touch operation data;
step 2023: and responding to the matching of the holding gesture adopted by the user and the holding gesture indicated by the prompt information, acquiring holding gesture data corresponding to the holding gesture adopted by the user for holding the electronic equipment, and performing touch operation data corresponding to the touch operation.
Further, the touch operation data may include a sliding track between the operation part of the user and the touch panel, and the step 2022 determines whether the holding posture adopted by the user matches the holding posture indicated by the prompt information according to the touch operation data may include: determining an operation part corresponding to the touch operation according to the operation part of the user and the sliding track of the touch panel; and determining whether the holding gesture adopted by the user is matched with the holding gesture indicated by the prompt information or not according to the operation part corresponding to the touch operation and the holding part corresponding to the holding gesture indicated by the prompt information.
It should be noted that, when the user performs the holding operation and the touch operation according to the prompt information, data of the holding gesture and the touch operation are detected. However, in order to determine the correctness of the acquired data, verification needs to be performed, and one way may be to determine an operation portion corresponding to the touch operation according to the operation portion of the user and the sliding track of the touch panel, and verify whether the holding gesture adopted by the user matches the holding gesture indicated by the prompt information according to the operation portion corresponding to the touch operation and the holding portion corresponding to the holding gesture indicated by the prompt information.
Further, the determining, according to the operation portion corresponding to the touch operation and the holding portion corresponding to the holding gesture indicated by the prompt information, whether the holding gesture adopted by the user matches the holding gesture indicated by the prompt information may include: if the operation part is a thumb and belongs to a hand corresponding to the holding part, determining that the holding posture adopted by the user is matched with the holding posture indicated by the prompt information; or if the operation part is a finger and does not belong to the hand corresponding to the holding part, determining that the holding posture adopted by the user is matched with the holding posture indicated by the prompt information.
For example, when the holding gesture indicated by the prompt information is left-handed holding and the detected operation part of the user is the left thumb, it may be determined that the user is left-handed holding or left-handed operation, that is, the holding gesture adopted by the user matches the holding gesture indicated by the prompt information; if the holding gesture prompted by the prompt message is left-handed holding, and the detected operation part of the user is the index finger of the right hand, the left-handed holding and the right-handed operation can be determined, namely the holding gesture adopted by the user is matched with the holding gesture indicated by the prompt message. When the user holds the hand, the user can perform touch operation with the thumb of the left hand or with any finger of the right hand, and whether the holding part adopted by the user is correct can be verified reversely by determining the operation part corresponding to the touch operation.
Further, when the holding portion and the operation portion of the user belong to the same hand, the operation portion may be a finger, and determining the operation portion corresponding to the touch operation according to the sliding track between the operation portion of the user and the touch panel may include: determining a midpoint according to a starting point of the sliding track and an end point of the sliding track, wherein the midpoint is a midpoint of a connecting line of the starting point and the end point; determining an intersection point of a perpendicular bisector of the sliding track and the sliding track; and determining an operation part corresponding to the touch operation according to the magnitude relation between the difference value of the abscissa of the midpoint and the intersection point and a difference value threshold, wherein if the difference value is greater than the difference value threshold, the operation part is a right hand finger, and if the difference value is less than the difference value threshold, the operation part is a left hand finger.
It should be noted that, according to the sliding data entered by the user, the positions of the finger joints relative to the mobile phone screen are calculated by combining the movement characteristic trajectories of the finger joints of the human body with ergonomics, so that the mobile phone operator can hold the mobile phone with one left hand, one right hand or both hands. The trajectory calculation can assist in interpreting the holding posture, and can also be used for conjecturing the contact area of the tiger's mouth and the big thenar by combining the acquired holding posture data for restraining the area setting.
For example, fig. 6 is a schematic diagram of a thumb sliding track provided in an embodiment of the present application, as shown in fig. 6, a coordinate system is preset on a screen of an electronic device, a lower left corner of the electronic device facing a user's sight line is used as an origin, an x axis is a lower edge line of the electronic device, a y axis is a left edge line of the electronic device, left and right hand operation judgment is recognized by using track data, and a corresponding geometric relationship is shown in fig. 6. The identification method comprises the following steps: first, process (x) 1 ,y 1 ) And (x) 2 ,y 2 ) Midpoint of straight line segment (x) z ,y z ) Making a perpendicular bisector L and intersecting the arc line at (x) 0 ,y 0 ) And (4) point. Midpoint:
the perpendicular bisector L:
by calculating (x) z ,y z ) And (x) 0 ,y 0 ) The relative coordinate position of (a) determines whether the thumb is operated to slide the screen with the left hand or the right hand, when (x) z -x 0 )>When 0, the mobile phone is operated by the right hand, when (x) z -x 0 )<And when 0, the mobile phone is operated by the left hand.
Further, when the holding portion and the operation portion of the user do not belong to the same hand, the operation portion may be a finger, and determining the operation portion corresponding to the touch operation according to the sliding track between the operation portion of the user and the touch panel may include: and determining an operation part corresponding to the touch operation according to the fingerprint characteristics of the sliding track.
It can be understood that the preset identification model arranged in the electronic device can be used for learning and marking according to the fingerprint characteristics of click capacity data, and the touch finger type, namely the finger action of the left hand and the right hand, can be accurately identified. Thus, after the user inputs click data or swipe data, it is possible to determine which finger of which hand is operated from the fingerprint.
Fig. 7 is a flowchart of another method for preventing false touch according to an embodiment of the present application, and as shown in fig. 7, on the basis of the embodiment shown in fig. 3, after step 203, that is, after obtaining the holding gesture data and the touch operation data generated by the user in the plurality of holding gestures, the method may further include:
step 204: and determining a corresponding inhibition area under each holding gesture according to the holding gesture data and the touch operation data generated under each holding gesture.
It should be noted that, by analyzing the holding posture data and the touch operation data corresponding to one holding posture, the suppression area corresponding to the holding posture can be determined, and after processing the holding posture data and the touch operation data corresponding to each of the plurality of holding postures by the same method, the suppression area corresponding to each holding posture is obtained, and the suppression area data can be used for training the preset recognition model.
Step 205: and training the preset recognition model according to the holding posture data, the touch operation data and the corresponding inhibition area under each holding posture generated under the plurality of holding postures to obtain the trained recognition model.
It should be noted that a preset identification model is built in the electronic device before the electronic device leaves the factory, and the model can accurately identify the touch finger type, that is, which finger motion of the left hand and the right hand, by learning and marking the fingerprint features of the click-through capacity data by using a disclosed image feature deep learning method. Due to the fact that the characteristics of the hands of each user are different, the preset recognition model is trained by using the characteristic data of personal holding and touch of the user, and the accuracy of the model can be further improved.
In this embodiment, 80% of the acquired holding posture data and touch operation data generated by the user in the plurality of holding postures can be used as a training set, and 20% of the acquired holding posture data and touch operation data can be used as a checking set to be applied to a preset recognition model for correction, so that the model recognition accuracy can be greatly improved after the model is corrected.
In some embodiments, the electronic device has a plurality of suppression areas preset therein, and the step 204 determines, according to the holding posture data and the touch operation data generated in each of the holding postures, a suppression area corresponding to each of the holding postures, which may include: determining a target inhibition area corresponding to the holding posture; acquiring holding posture data in the target inhibition area in the holding posture data; determining at least one polygon according to the holding posture data in the target inhibition area; determining a maximum bounding rectangle of the at least one polygon; and determining the maximum circumscribed rectangle as a corresponding inhibition area under the holding posture.

It should be noted that each holding posture may have a corresponding preset suppression area, so that after the holding posture is determined, the range of the corresponding suppression area that needs to be suppressed, that is, the corresponding target suppression area, may be determined, then the holding posture data in the target suppression area may be obtained, the corresponding polygon may be determined according to the holding posture data, and the maximum circumscribed rectangle of the polygon may be solved, where the maximum circumscribed rectangle is the corresponding suppression area.
The calculation method of the rectangular area of the inhibition area in the holding posture can be as follows: and acquiring irregular graphs corresponding to the acquired touch screen capacitance value change data under the holding gesture, and calculating the maximum external rectangle of the irregular graphs.
