It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0024] IME smart surface touch buttons can be made through screen printing technology. By detecting whether the capacitance of the touch button changes, it can be judged whether there is a finger touch operation. Compared with mechanical buttons, touch buttons are beautiful in appearance, easy to use, and have a long life. However, considering that if there is a water film or water droplets on the touch button, the capacitance of the touch button will be changed, and false touch sensing may occur. In addition, the touch button cannot effectively prevent false touch of human skin. If the human skin touches it unintentionally, it will also cause false touch sensing.
[0025] In view of this, the present disclosure provides a method, system, vehicle, medium and program product for preventing false touches of touch keys. When a touch operation is detected, whether the touch operation is a false touch operation is determined based on the pressure-related parameter change information of the touch panel and the capacitance-related parameter change information of the touch key, and then the touch operation is shielded when it is determined to be a false touch operation. In this way, it is possible to effectively identify whether the touch operation is a false touch operation, thereby avoiding the problem of false triggering of keys due to false touches, and improving the user experience.
[0026] Before describing in detail the specific implementation of the method for preventing accidental touch of a touch key provided by the present disclosure, first, the system for preventing accidental touch of a touch key provided by the present disclosure is described.
[0027] Figure 1 FIG. 1 is a block diagram of a touch key anti-mistouch system according to an exemplary embodiment. Figure 1 As shown, the touch button anti-mis-touch system 100 may include a touch panel 101, a pressure detection device 102 and a control device 103. Among them, a plurality of touch buttons 1011 are arranged on the touch panel 101, the pressure detection device 102 is used to detect the pressure-related parameter change information of the touch panel 101, and the control device 103 is respectively connected to the touch button 1011 and the pressure detection device 102, and is used to execute the steps of the touch button anti-mis-touch method provided in the present disclosure. Among them, the touch button anti-mis-touch method will be described in detail below.
[0028] In the present disclosure, the touch key is a capacitive key. When a user touches the touch key, the capacitance value of the touch key changes. Therefore, whether the touch key is touched can be determined based on whether the capacitance value of the touch key changes. It should be understood that there can be multiple touch keys. Figure 1 In the description, four touch buttons are taken as an example. In actual applications, the number of touch buttons may be more or less, and the present disclosure does not make any specific limitation on this.
[0029] In addition, when the user touches the touch panel intentionally or unintentionally, the user will apply pressure to the touch panel 101 , and then the pressure detection device 102 can detect the pressure-related parameter change information of the touch panel where the touch key is located.
[0030] By adopting the above technical solution, the control device is connected to the touch button and the pressure detection device respectively, and when the touch operation on the touch button is detected, the pressure-related parameter change information of the touch panel and the capacitance-related parameter change information of each touch button can be obtained respectively, and then the shielding touch operation is determined according to the pressure-related parameter change information and the capacitance-related parameter change information. In this way, it is possible to effectively identify whether the touch operation is an erroneous touch operation, thereby avoiding the problem of erroneous triggering of the button due to erroneous touch, and improving the user experience.
[0031] In one embodiment, the touch panel 101 includes a first carrier film 1012, a second carrier film 1013 and a plastic layer 1014, wherein the first carrier film 1012 and the second carrier film 1013 are both disposed on the surface of the plastic layer 1014. The first carrier film 1012 includes a light-transmitting area 10121, and a touch button 1011 is printed on the second carrier film 1013 and below the light-transmitting area 10121.
[0032] It should be understood that printing the touch button 1011 on the second carrier film 1013 below the light-transmitting area 10121 means that the light-transmitting area 10121 is located above the touch button 1011 arranged on the second carrier film 1013 to ensure visualization of the light-transmitting area 10121 .
[0033] In one implementation of this embodiment, the first carrier membrane 1012 and the second carrier membrane 1013 are separately provided. For example, Figure 2 FIG. 1 is a schematic diagram of a touch panel according to an exemplary embodiment. Figure 2 As shown, the first carrier film 1012 is disposed on the upper surface of the plastic layer 1014, and the second carrier film 1013 is disposed on the lower surface of the plastic layer 1014. The first carrier film 1012 includes a light-transmitting area 10121, and a touch button 1011 is printed on the second carrier film 1013 and below the light-transmitting area 10121. In this way, the touch buttons are visualized, and it is convenient for users to touch different touch buttons according to different needs.
[0034] The first carrier film 1012 and the second carrier film 1013 can be made of polycarbonate (PC), polyimide (PI), polypropylene (PP), PEP, etc. The thickness of the first carrier film 1012 and the second carrier film 1013 ranges from [0.15 mm to 0.5 mm]. Figure 2In the embodiment, the first carrier film 1012 and the second carrier film 1013 can be combined by insert injection molding, or by injection molding and gluing. For example, the injection molding and gluing method is that after the first carrier film 1012 is injection molded, the second carrier film 1013 is glued together with the injection molded first carrier film 1012 by adhesive.
[0035] The area on the first carrier film 1012 may be all light-transmitting areas, or part of the area may be light-transmitting areas and part of the area may be opaque areas. Considering that the pressure detection device is usually arranged on the back of the touch panel, in order to avoid visualization of the pressure detection device for aesthetics, in the present disclosure, the area on the first carrier film 1012 includes the light-transmitting area 10121 and the opaque area 10122 as an example.
[0036] For example, Figure 2 As shown, a light-transmitting ink can be screen-printed on the first carrier film 1012 to form a light-transmitting area 10121, and a light-isolating ink can be screen-printed to form a light-impermeable area 10122. The light-transmitting area 10121 and the light-impermeable area 10122 can be evenly spaced. It should be understood that the light-transmitting area 10121 and the light-impermeable area 10122 can also be unevenly spaced, and the present disclosure does not specifically limit this.
[0037] The second carrier film 1013 is provided with a touch button 1011. The touch button 1011 can be attached to the second carrier film 1013 by screen printing. In order to facilitate the user to view and select the touch button to be touched, the beacon of the touch button needs to be visualized. Figure 2 As shown, the touch button 1011 is printed on the second carrier film 1013 and in the area below the light-transmitting area 10121. In addition, the size of the touch button 1011 disposed on the second carrier film 1013 is greater than or equal to 8 mm x 8 mm.
[0038] The first carrier film 1012 and the second carrier film 1013 are respectively arranged on the upper and lower surfaces of the plastic layer 1014 by insert injection molding or injection molding plus pasting. In the process of injection molding and pasting, the first carrier film 1012 and the second carrier film 1013 cannot generate bubbles, and the relative dielectric constant of the plastic layer 1014 is greater than or equal to 2, and the thickness of the plastic layer is less than 5mm. In addition, the thinner the dielectric layer between the touch button and the user's finger, and the larger the size of the touch button, the greater the voltage change value converted from the capacitance change value.
[0039] In another implementation of this embodiment, the first carrier film 1012 and the second carrier film 1013 are integrated on the upper surface of the plastic layer 1014 , and the second carrier film 1013 is located below the first carrier film 1012 . Figure 3FIG. 1 is a schematic diagram of another touch panel according to an exemplary embodiment. Figure 3 As shown, the carrier film after the first carrier film 1012 and the second carrier film 1013 are integrated can be called an integrated carrier film 1015. The integrated carrier film 1015 is arranged on the upper surface of the plastic layer 1014. The upper surface of the integrated carrier film 1015 is the first carrier film, including a light-transmitting area. For example, the area on the upper surface of the integrated carrier film 1015 can be all light-transmitting areas 10121, or part of the area is the light-transmitting area 10121 and part of the area is the opaque area 10122. The light-transmitting area 10121 and the opaque area 10122 are formed as follows: Figure 2 The above is not repeated here.
[0040] The lower surface of the integrated carrier film 1015 is a second carrier film provided with a touch button 1011. The specific setting method of the touch button 1011 is as described above and will not be repeated here. It should be understood that when the first carrier film 1012 and the second carrier film 1013 are integrated, the size of the touch button 1011 should be greater than or equal to 4mmx4mm.
[0041] In addition, Figure 2 and Figure 3 In addition to the touch button 1011, the second carrier module 1013 is also provided with a conductive circuit 1016, and the conductive circuit 1016 is used to transmit electrical signals. For example, the control device 103 obtains the capacitance-related parameter change information of the touch button through the conductive circuit 1016. The conductive circuit 1016 and the touch button 1011 are conductive silver paste or transparent conductive ink, and the setting positions of the conductive circuit 1016 and the touch button 1011 do not overlap. In addition, the conductive circuit 1016 can also be attached to the second carrier module 1013 or the lower surface of the integrated carrier membrane 1015 through a screen printing process.
[0042] In one embodiment, the pressure detection device 102 is independently provided with the touch panel 101. For example, the pressure detection device 102 can be provided on the back of the touch panel 101. For example, the pressure detection device 102 is bonded to the back of the touch panel 101, or the pressure detection device 102 contacts the plastic column 10141 provided on the lower surface of the plastic layer 1014.
[0043] In one implementation of this embodiment, Figure 2 Take the touch panel shown as an example. Figure 4A and Figure 4B FIG. 1 is a schematic diagram of a touch key anti-mistouch system according to an exemplary embodiment. Figure 4A In the embodiment, the pressure detection device 102 is bonded to the entire back side of the second carrier module 1013. Figure 4B In the embodiment, a plastic column 10141 is connected to the lower surface of the plastic layer 1014, and the pressure detection device 102 is arranged in contact with the plastic column 10141. If the length of the second carrier module 1013 is less than the length of the plastic layer 1014, the plastic column 10141 can be arranged on the lower surface of the plastic layer 1014 and at a position not in contact with the second carrier module 1013. If the length of the second carrier module 1013 is greater than or equal to the length of the plastic layer 1014, a hole can be opened on the second carrier module 1013 so that the plastic column 10141 on the lower surface of the plastic layer 1014 can contact with the pressure detection device 102 through the hole on the second carrier module 1013. Figure 4B In the figure, the length of the second carrier module 1013 is equal to the length of the plastic layer 1014 .
[0044] In another implementation of this embodiment, Figure 3 Take the touch panel shown as an example. Figure 5A and Figure 5B FIG. 1 is a schematic diagram of another touch key anti-mistouch system according to an exemplary embodiment. Figure 5A In the embodiment, the pressure detection device 102 is bonded to the lower surface of the plastic column 10141. Figure 5B In the figure, a plastic column 10141 is connected to the lower surface of the plastic layer 1014 , and the pressure detection device 102 is arranged in contact with the plastic column 10141 .
[0045] It should be understood that in Figures 4A to 5B The minimum pressure range detected by the pressure detection device can be [10N, 50N], and the minimum deformation range caused by pressure can be [0.1μm, 1μm].
[0046] In another embodiment, the pressure detection device 102 may include at least two pressure sensors 1021, and the pressure sensors 1021 may be integrated in the touch panel 101. For example, each pressure sensor 1021 is disposed on the second carrier membrane 1013 at a position different from the touch button 1011.
[0047] Taking geometric symmetry into consideration, when two pressure sensors 1021 are arranged on the symmetry axis of multiple touch keys, it may not be possible to accurately locate the touch positions on the symmetry axis of the two pressure sensors 1021 and the touch positions at the symmetric positions of the touch panel 101. Therefore, when the pressure detection device 102 includes two pressure sensors 1021, the two pressure sensors 1021 are arranged on the asymmetric axis of multiple touch keys.
[0048] In one implementation of this embodiment, Figure 2 Take the touch panel shown as an example. Figure 6FIG. 1 is a schematic diagram of another touch key anti-mistouch system according to an exemplary embodiment. Figure 6 As shown, the pressure detection device 102 may include three pressure sensors 1021 , and the three pressure sensors 1021 are all arranged on the second carrier membrane 1013 and at positions different from the touch button 1011 .
[0049] In another implementation of this embodiment, Figure 3 Take the touch panel shown as an example. Figure 7 FIG. 1 is a schematic diagram of another touch key anti-mistouch system according to an exemplary embodiment. Figure 7 As shown, the pressure detection device 102 may include three pressure sensors 1021 , and the three pressure sensors 1021 are all arranged on the lower surface of the integrated carrier membrane 1015 and at positions different from the touch button 1011 .
[0050] exist Figure 6 and Figure 7 In the embodiment, considering that the pressure sensor is integrated in the touch panel 101, the minimum pressure range detected by the pressure sensor may be [5N, 50N]. Figure 7 In the structure shown, the minimum deformation caused by pressure ranges from [10nm to 1μm].
[0051] It should be understood that in the present disclosure, the pressure sensor 1021 can be disposed on the second carrier diaphragm 1013 or on the lower surface of the integrated carrier diaphragm 1015 through a pad. The pad can be a conductive silver paste or a transparent conductive ink, which is attached to the second carrier diaphragm 1013 or the lower surface of the integrated carrier diaphragm 1015 through a screen printing process.
[0052] In this way, by utilizing the anti-mistouch system for touch buttons provided by the present disclosure, it is possible to effectively identify whether a touch operation is a mistouch operation, thereby avoiding the problem of mistouch triggering of buttons due to mistouch, thereby improving the user experience.
[0053] The specific implementation of the method for preventing accidental touch of a touch button provided by the present disclosure is described below.
[0054] Figure 8 FIG. 1 is a flow chart of a method for preventing accidental touches of a touch key according to an exemplary embodiment. The method can be applied to the control device 103 in the system for preventing accidental touches of a touch key provided in the present disclosure. Figure 8 As shown, the method may include the following steps.
[0055] In step S81, in response to detecting a touch operation on a touch key, pressure-related parameter change information of the touch panel where the touch key is located and capacitance-related parameter change information of each touch key are respectively acquired.
[0056] In the present disclosure, if only a touch operation on a non-touch key in the touch panel is detected, there is no need to further determine whether the trigger operation is a false trigger operation, that is, only when there is a touch operation on a touch key is it necessary to further determine whether the touch operation is a false touch operation. Therefore, when the control device 103 detects a touch operation on a touch key, it respectively detects the pressure-related parameter change information of the touch panel and the capacitance-related parameter change information of each touch key.
[0057] In the present disclosure, the control device 103 can detect whether there is a touch operation on the touch key according to any detection method. However, considering that the touch key is usually a capacitive key, if the touch key is touched, the capacitance-related parameters of the touch key will change. Therefore, in one possible method, the control device 103 can obtain the capacitance-related parameter change information of each touch key, and if there is a target touch key whose capacitance change value is not zero according to the capacitance-related parameter change information, it is determined that a touch operation on the target touch key is detected, and then further obtain the pressure-related parameter change information of the touch panel where the touch key is located.
[0058] For example, a pressure detection device is provided below the touch panel, and the control device 103 can obtain the pressure-related parameter change information of the touch panel where the touch button is located through the pressure detection device.
[0059] In the present disclosure, the pressure-related parameter may include one of the following: a pressure parameter, a voltage parameter corresponding to the pressure parameter, and a piezoresistive parameter corresponding to the pressure parameter. Among them, the technology of obtaining the pressure parameter, the voltage parameter corresponding to the pressure parameter, or the piezoresistive parameter corresponding to the pressure parameter through the pressure detection device is a relatively mature technology, and the present disclosure does not limit this.
[0060] The capacitance-related parameter change information may include a capacitance parameter or a voltage parameter corresponding to the capacitance parameter.
[0061] In step S82, a shielded touch operation is determined according to the pressure-related parameter change information and the capacitance-related parameter change information.
[0062] For example, according to the pressure-related parameter change information and the capacitance-related parameter change information, it is determined that the touch operation is a false touch operation, and then it is determined to shield the touch operation.
[0063] By adopting the above technical solution, when a touch operation on a touch key is detected, the pressure-related parameter change information of the touch panel and the capacitance-related parameter change information of each touch key are obtained respectively, and whether it is an erroneous touch operation is determined according to the pressure-related parameter change information and the capacitance-related parameter change information, and then the touch operation is shielded when it is determined that the touch operation is an erroneous touch operation. In this way, it is possible to effectively identify whether the touch operation is an erroneous touch operation, thereby avoiding the problem of erroneous triggering of keys due to erroneous touches, and improving the user experience.
[0064] In one embodiment, step S82 determines the shielding touch operation based on the pressure-related parameter change information and the capacitance-related parameter change information, and may include: determining the shielding touch operation when the pressure change value represented by the pressure-related parameter change information and / or the capacitance change value represented by the capacitance-related parameter change information is zero.
[0065] For example, when the pressure change value represented by the pressure-related parameter change information is zero and the capacitance change value represented by the capacitance-related parameter change information is not zero, it is determined that the touch operation is an erroneous operation, and the touch operation is shielded.
[0066] As another example, when the pressure change value represented by the pressure-related parameter change information is not zero and the capacitance change value represented by the capacitance-related parameter change information is zero, it is determined that the touch operation is an erroneous operation, and the touch operation is shielded.
[0067] As another example, when the pressure change value represented by the pressure-related parameter change information is zero and the capacitance change value represented by the capacitance-related parameter change information is zero, it is determined that the touch operation is an erroneous operation, and the touch operation is shielded.
[0068] Fig. 9A and 9B FIG. 1 is a schematic diagram showing a method of pressing a touch key according to an exemplary embodiment. Fig. 9A In the example, the user touches the touch key surface with his finger, and the voltage change value of the touch key is not 0. However, due to the small pressing force, the touch panel does not produce effective deformation, that is, the voltage change value corresponding to the pressure parameter is 0. At this time, it can be determined that the touch key is not triggered, that is, the touch operation is considered to be an erroneous touch operation. Fig. 9B In the example, when a user presses the touch button surface with his finger, the voltage change value of the touch button is not 0, and the voltage change value corresponding to the pressure parameter is also not 0. At this time, the touch operation can be considered as an intentional touch operation, and a corresponding action is performed in response to the touch operation.
[0069] In addition, the method may further include: If the pressure-related parameter change information indicates that the change value of the pressure-related parameter is not zero, and the capacitance-related parameter change information indicates that the change value of the capacitance-related parameter is not zero, then the touch operation is determined to be an intentional touch operation, and then it is determined not to shield the touch operation, that is, a corresponding action is performed in response to the touch operation.
[0070] In another embodiment, the method may further include: Determine that the pressure change value represented by the pressure-related parameter change information and the capacitance change value represented by the capacitance-related parameter change information are not zero at the same time; Acquire a first touch position on the touch panel; Acquire a second touch position on the touch panel; A shielding touch operation is determined according to the first touch position and the second touch position.
[0071] In this embodiment, the first touch position and the second touch position may be acquired by any sensor capable of acquiring a touch position, and the present disclosure does not limit this.
[0072] In one embodiment, obtaining the first touch position on the touch panel may include: determining the first touch position on the touch panel according to pressure-related parameter change information. Obtaining the second touch position on the touch panel may include: determining the second touch position on the touch panel according to capacitance-related parameter change information.
[0073] Among them, the specific implementation method of obtaining the first touch position on the touch panel can be: obtaining a first corresponding relationship between preset pressure-related parameter change information and the touch position; and obtaining the first touch position on the touch panel according to the first corresponding relationship and the pressure-related parameter change information.
[0074] In this embodiment, the first correspondence between the pressure-related parameter change information and the touch position can be preset. For example, the first correspondence between the pressure-related parameter change information and the touch position is obtained by acquiring the pressure-related parameter change information detected by the pressure detection device when the touch key is pressed.
[0075] The pressure detection device includes at least two pressure sensors; if the pressure detection device includes two pressure sensors, the two pressure sensors are arranged on the asymmetric axes of the plurality of touch keys.
[0076] Fig.10 FIG. 1 is a schematic diagram showing the distribution of a touch button and a pressure detection device according to an exemplary embodiment. Fig.10As shown, it is assumed that four touch buttons are provided on the touch panel, which are respectively recorded as the first touch button, the second touch button, the third touch button and the fourth touch button. In addition, the pressure detection device includes two pressure sensors, which are respectively recorded as the first pressure sensor and the second pressure sensor, wherein the first pressure sensor and the second pressure sensor are arranged on the asymmetric axis of the above four touch buttons. The touch buttons can be pressed under different pressing conditions, and the change values of the pressure-related parameters of the first pressure sensor and the second pressure sensor and the pressing position are recorded each time the pressing is performed. Among them, the pressing conditions include the conditions where a single touch button is pressed, multiple buttons are pressed in combination, and a part of the touch panel is pressed and the entire touch panel is pressed.
[0077] For example, Fig.10 As shown, the pressing conditions may include pressing each of the four touch keys individually, pressing two, three and four of the four touch keys simultaneously, pressing a partial touch panel and pressing the entire touch panel. For each pressing, the pressure-related parameter change values of the first pressure sensor and the second pressure sensor during the pressing and the position of the pressing are recorded to obtain a first corresponding relationship between the pressure-related parameter change information and the touch position.
[0078] It should be understood that if the pressure detection device includes N pressure sensors, the determined first corresponding relationship refers to the corresponding relationship between the pressure-related parameter change information of the N pressure sensors and the touch position.
[0079] When a touch operation on a touch key is detected, a first touch position on the touch panel may be obtained according to the acquired pressure-related parameter change information and the above-mentioned first corresponding relationship.
[0080] In addition, a specific implementation of obtaining the second touch position on the touch panel may be: determining a target touch key corresponding to the touch operation according to capacitance-related parameter change information; and determining the position of the target touch key as the second touch position on the touch panel.
[0081] For example, a second correspondence relationship between each touch key and a position may be preset. When the capacitance-related parameter change information of each touch key is obtained, a touch key whose capacitance-related parameter change value is not zero is determined as a target touch key, and then the position corresponding to the target touch key is determined according to the second correspondence relationship, and the position is determined as the second touch position.
[0082] After the first touch position and the second touch position are respectively determined, a shielding touch operation is determined according to the first touch position and the second touch position.
[0083] In the present disclosure, whether a touch operation is an erroneous operation is comprehensively determined based on a first touch position determined based on pressure-related parameter change information and a second touch position determined based on capacitance-related parameter change information, and the touch operation is shielded when it is determined that the touch operation is an erroneous operation.
[0084] In an embodiment, determining the shielding touch operation according to the first touch position and the second touch position may include: if the distance between the first touch position and the second touch position is greater than a preset distance value, determining the shielding touch operation.
[0085] If the distance between the first touch position and the second touch position is greater than the preset distance value, it is considered that the user has pressed other positions on the touch panel in addition to the touch button, and the other positions are far away from the touch button. At this time, the probability that the user intentionally presses the touch button is low. Therefore, the touch operation can be determined as a false touch operation. In order to avoid false button responses, the touch operation can be blocked.
[0086] In addition, the method may further include: If the distance between the first touch position and the second touch position is less than or equal to a preset distance value, a corresponding action is performed in response to the touch operation.
[0087] In this embodiment, if the distance between the first touch position and the second touch position is less than or equal to the preset distance value, it is considered that the user intentionally touches the touch button, that is, the touch operation is determined to be an intentional touch operation. At this time, in order to meet the user's needs, a corresponding action can be performed in response to the touch operation. For example, if the touch operation is an operation of touching a touch button for controlling the on-board air conditioner, the on-board air conditioner is controlled to turn on in response to the touch operation.
[0088] In one embodiment, the preset distance value may be 0, so that when the first touch position is the same as the second touch position, the touch operation is determined to be an intentional touch operation, and a corresponding action is performed in response to the touch operation. When the first touch position is different from the second touch position, the touch operation is determined to be an erroneous touch operation, and the touch operation is shielded.
[0089] Fig.11 FIG. 1 is a schematic diagram showing an error touch operation according to an exemplary embodiment. Fig.11 As shown, the first touch position determined based on the pressure-related parameter change information includes not only the position of the touch button but also other positions on the touch panel, and the other positions are far away from the touch button, then the touch operation is determined as an erroneous touch operation, and in this case, the touch operation can be shielded.
[0090] Fig.12 FIG. 1 is a flow chart of another method for preventing accidental touch of a touch key according to an exemplary embodiment. Fig.12 As shown, the method may include the following steps.
[0091] In step S121, in response to detecting a touch operation on a touch key, pressure-related parameter change information of the touch panel where the touch key is located and capacitance-related parameter change information of each touch key are respectively acquired.
[0092] In step S122, a first touch position on the touch panel is determined according to the pressure-related parameter change information.
[0093] For example, a first correspondence relationship between preset pressure-related parameter change information and a touch position is obtained; and a first touch position on the touch panel is obtained according to the first correspondence relationship and the pressure-related parameter change information.
[0094] In step S123, a second touch position on the touch panel is determined according to the capacitance-related parameter change information.
[0095] For example, a target touch key corresponding to the touch operation is determined according to the capacitance-related parameter change information; and a position of the target touch key is determined as a second touch position on the touch panel.
[0096] The order of step S122 and step S123 is not specifically limited. For example, step S122 may be performed first and then step S123, or step S123 may be performed first and then step S122. Step S122 and step S123 may also be performed simultaneously. Fig.12 In the example, step S122 is executed first and then step S123 is executed.
[0097] In step S124, if the distance between the first touch position and the second touch position is less than or equal to the preset distance value, a corresponding action is performed in response to the touch operation.
[0098] In step S125 , if the distance between the first touch position and the second touch position is greater than a preset distance value, it is determined that the touch operation is shielded.
[0099] By adopting the above technical solution, when a touch operation on a touch key is detected, the pressure-related parameter change information of the touch panel and the capacitance-related parameter change information of each touch key are obtained respectively, and then whether to shield the touch operation is determined according to the pressure-related parameter change information and the capacitance-related parameter change information. In this way, it is possible to effectively identify whether the touch operation is an erroneous touch operation, thereby avoiding the problem of erroneous triggering of keys due to erroneous touches, and improving the user experience.
