Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The embodiments and features of the embodiments of the present invention may be arbitrarily combined with each other without conflict. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
In addition, the term "or/and" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" in this document generally indicates that the preceding and following related objects are in an "or" relationship unless otherwise specified.
In the embodiment of the present invention, the electronic device may include a mobile phone, a tablet computer (PAD), and the like, although the type of the electronic device in the embodiment of the present invention is not limited thereto. The pressure sensing area may be an area on the electronic device, for example, an area on a touch screen of the electronic device, and the electronic device may sense the pressure sensing area by a user pressing the pressure sensing area.
A touch screen provided on an electronic device is an input device that can receive an input signal such as pressure, and when a user touches a surface of the touch screen through an operation body, pressure may be applied to the touch screen, and the electronic device can detect and recognize the pressure, so that the electronic device can perform a corresponding operation according to the recognized pressure. For example, a user applies pressure to the touch screen, and if information corresponding to the pressure corresponds to a certain trigger instruction preset in the electronic device, the electronic device may execute the trigger instruction to complete a corresponding function. The user can know in advance which kind of pressure corresponds to which kind of response mode of electronic equipment to only need when needing electronic equipment to accomplish corresponding function exert on the touch-sensitive screen corresponding pressure can, it is comparatively convenient to operate. In this case, the electronic device is required to respond to the operation of the user accurately, on the premise that the pressure sensitivity of the touch panel of the electronic device is not changed as much as possible, and when the pressure sensitivity is not changed, the electronic device can respond to the same pressure applied by the user.
However, in the use process of the electronic device, the touch screen may deform, and the distance between two poles of the capacitor disposed under the touch screen may become small, thereby causing the pressure sensitivity of the touch screen to change. For example, if a user applies pressure 1, the electronic device itself should respond 1, but if the distance between two electrodes of the capacitor under the touch screen becomes small, the electronic device may respond 1 when the user applies pressure 2 smaller than the pressure 1, and it is known that the deformation of the electronic device may cause a change in the pressure sensitivity of the touch screen, and thus the false response rate of the electronic device is high.
In view of these problems, the following provides a technical solution of an embodiment of the present invention, and by using the technical solution provided by the embodiment of the present invention, the electronic device can automatically adjust the pressure sensitivity that changes, so that the error response rate of the electronic device can be reduced. The technical scheme provided by the embodiment of the invention is described in the following with reference to the accompanying drawings.
Referring to fig. 1, a method for adjusting the sensitivity of a pressure sensing area according to an embodiment of the present invention is described as follows.
Step 101: executing a control instruction, wherein the control instruction is used for instructing and adjusting the pressure sensitivity of the pressure sensing area;
step 102: determining a target adjustment region from the pressure sensing region; the target adjustment area is a partial area in the pressure sensing area;
step 103: obtaining an adjustment value for a target adjustment region;
step 104: the pressure sensitivity of the target adjustment region is adjusted based on the adjustment value.
When the pressure sensitivity of the touch screen needs to be adjusted, a user can operate the electronic device, so that the electronic device can generate a control instruction according to the operation of the user. For example, a button, which may be a software button or a hardware button, may be provided on the electronic device, and when the user triggers the button, the electronic device may generate a control command, so as to adjust the pressure sensitivity of the pressure sensing area.
The electronic device may determine a target adjustment region from the pressure sensing region after responding to the control command to adjust the pressure sensitivity of the target adjustment region. The target adjustment zone may be a partial zone or a full zone of the pressure sensing zone. For example, the pressure sensing area may be divided into a plurality of sub-areas, which may be divided by a user, or may be set by the electronic device when the electronic device leaves a factory, the shapes of different sub-areas may be the same or different, the areas of different sub-areas may be the same or different, and for different electronic devices, the number of sub-areas may also be different, which is not limited in the embodiment of the present invention. For example, for an electronic device, 3 × 3 sub-regions may be equally divided on the pressure-sensitive area of the touch screen of the electronic device, similar to the form of a grid of nine squares, or several sub-regions may be randomly divided on the pressure-sensitive area of the touch screen of the electronic device, and since the sub-regions are randomly divided, the areas, shapes, and the like of the sub-regions may be different, and these dividing manners are merely examples and are not limitations of the embodiments of the present invention.
In the embodiment of the present invention, the capacitance of any one sub-region may be regarded as a capacitance between the surface of the sub-region and a Ground (GND) of the electronic device, where the surface of the sub-region and the ground of the electronic device are two plates of the capacitance of the sub-region respectively, and a dielectric is filled between the two plates, and taking any one of the sub-regions as an example, the capacitance value of the sub-region may be calculated by using the following formula:
C＝εS/4πkd (1)
in equation (1), ε is the dielectric constant of the dielectric between the two plates of the sub-region 'S capacitance, S is the area of the sub-region, k is the electrostatic constant, and d is the distance between the two plates of the sub-region' S capacitance. As can be seen from equation (1), the capacitance value of the sub-region is inversely proportional to the distance between the two plates of the capacitance of the sub-region when the area of the sub-region is not changed. As can be known from the foregoing analysis, a change in a distance between two plates of a capacitance of the sub-region may also cause a change in the pressure sensitivity of the touch screen, and therefore, if a capacitance value of the sub-region changes, it can be considered that the pressure sensitivity of the sub-region changes, and what is to be adjusted in the embodiment of the present invention is the pressure sensitivity of the sub-region with the changed pressure sensitivity, so in the embodiment of the present invention, the electronic device may determine the sub-region with the changed capacitance value as the target adjustment region. In addition, there may be one or more sub-regions in which the capacitance value changes, and the electronic device may determine part or all of the sub-regions in which the capacitance value changes as the target adjustment region.
How the electronics determine whether the capacitance value of the sub-area changes is described below. In the embodiment of the present invention, the electronic device may first obtain the capacitance value of each sub-region included in the pressure sensing region, and compare the capacitance value of each sub-region with the preset capacitance value of the corresponding sub-region, and if the capacitance value of the sub-region is inconsistent with the preset capacitance value corresponding to the sub-region, it is determined that the capacitance value of the sub-region has changed, for example, the capacitance value of the sub-region 1 is inconsistent with the preset capacitance value set for the sub-region 1, and it is determined that the capacitance value of the sub-region 1 has changed. The preset capacitance value may be a capacitance value corresponding to a reference pressure sensitivity, and the reference pressure sensitivity may be a pressure sensitivity of the touch screen after pressure calibration is performed when the touch screen leaves a factory, for example, after the touch screen leaves the factory and pressure calibration is performed, the capacitance value corresponding to each sub-region may be stored, which is the preset capacitance value. Because the preset capacitance value corresponds to the reference pressure sensitivity, the preset capacitance value can also be considered as a reference capacitance value, and if the capacitance value of the sub-region is inconsistent with the preset capacitance value set for the sub-region, it can be considered that the capacitance value of the sub-region deviates from the reference, that is, the capacitance value changes.
In the embodiment of the present invention, the preset capacitance value is set, including but not limited to the following two ways:
the first setting mode is as follows: the electronic device may set a preset capacitance value, and the preset capacitance value corresponding to each sub-region included in the pressure sensing region is the preset capacitance value, and when the capacitance value of any one sub-region is compared with the preset capacitance value, the capacitance value of the sub-region is compared with the preset capacitance value. For example, the touch screen is usually subjected to pressure calibration when being shipped from a factory, so that the pressure sensitivity of each sub-area included in the pressure sensing area is consistent, and the preset capacitance values corresponding to the pressure sensitivity of each sub-area may be the same or may have a small difference. Alternatively, if the electronic device does not need to accurately determine the capacitance variation of each sub-region, the electronic device may also set only one preset capacitance, and the embodiment of the present invention is not limited thereto.
The second setting mode is as follows: the electronic device may set a preset capacitance value for each sub-region included in the pressure sensing region, for example, the pressure sensing region includes K sub-regions, and the electronic device needs to set K preset capacitance values, and when comparing the capacitance value of the sub-region with the preset capacitance value, the capacitance value of the sub-region is compared with the preset capacitance value corresponding to the sub-region. For example, the touch screen is usually subjected to pressure calibration when leaving a factory, so that the pressure sensitivity of each sub-area included in the pressure sensing area is consistent, and at this time, preset capacitance values corresponding to the pressure sensitivity of each sub-area may not be the same or partially different, or may have a large difference, in this case, the electronic device may set the preset capacitance values for each sub-area, so that subsequent comparison results may be more accurate. Or, if the electronic device needs to determine the capacitance value change condition of each sub-region more accurately, the electronic device may also set a preset capacitance value for each sub-region, which is not limited in the embodiments of the present invention.
After determining the target adjustment region, the electronic device may determine an adjustment value of the target adjustment region to adjust the pressure sensitivity of the target adjustment region, where the adjustment value refers to an adjustment value of the pressure sensitivity. In the embodiment of the present invention, the adjustment value may be used to indicate an adjustment direction, such as a lifting direction or a lowering direction, and may also be used to indicate an adjustment magnitude, such as how much pressure sensitivity should be lifted specifically or how much pressure sensitivity should be lowered specifically. In the following, an example of any sub-region is described to describe how the electronic device determines the adjustment value of the sub-region.
In one embodiment, the electronic device may determine the adjustment direction of the sub-region according to a magnitude relationship between the capacitance value of the sub-region and a preset capacitance value of the sub-region. If the capacitance value of the sub-region is greater than the preset capacitance value of the sub-region, the electronic device may determine that the adjustment direction of the pressure sensitivity of the sub-region is a decreasing direction, that is, the pressure sensitivity of the sub-region needs to be decreased, and if the capacitance value of the sub-region is less than the preset capacitance value of the sub-region, the electronic device may determine that the adjustment direction of the pressure sensitivity of the sub-region is a increasing direction. I.e. the pressure sensitivity of the sub-region needs to be increased.
In this embodiment, after determining the adjustment value of the target adjustment region, the electronic device may generate a corresponding increase instruction or decrease instruction according to the adjustment value, and if the increase instruction is generated, the electronic device may increase the pressure sensitivity of the corresponding sub-region by executing the increase instruction, and if the decrease instruction is generated, the electronic device may decrease the pressure sensitivity of the corresponding sub-region by executing the decrease instruction. The lifting amplitude and the reducing amplitude can be preset, and the lifting amplitude and the reducing amplitude can be equal or unequal in value.
In one embodiment, the electronics can determine the adjustment magnitude of the pressure sensitivity from the difference between the capacitance value of the sub-region and a preset capacitance value of the sub-region. In this embodiment, the difference between the capacitance value of the sub-region and the predetermined capacitance value of the sub-region is determined, and thus the magnitude relationship between the capacitance value of the sub-region and the predetermined capacitance value of the sub-region is also known, so that the adjustment range can be determined in addition to the adjustment direction. The change of the capacitance value of one sub-area may cause the change of the pressure sensitivity of the sub-area, and if the change of the capacitance value is different, the change of the pressure sensitivity may also be different, for example, the larger the change of the capacitance value is, the larger the change of the pressure sensitivity may be, and the adjustment amplitude may be determined accordingly. The electronic device may preset a corresponding relationship between a variation range of the capacitance value and a variation range of the pressure sensitivity, and taking any one of the sub-regions included in the target adjustment region as an example, after the electronic device determines a difference between the capacitance value of the sub-region and a preset capacitance value of the sub-region, the variation range of the pressure sensitivity corresponding to the difference in the corresponding relationship may be determined by querying the corresponding relationship, so that the variation range of the queried pressure sensitivity may be determined as the adjustment range of the pressure sensitivity of the sub-region at this time.
In this embodiment, after determining the adjustment value of the target adjustment region, the electronic device may generate a corresponding lifting instruction or a corresponding lowering instruction according to the adjustment value, if the lifting instruction is generated, the electronic device may execute the lifting instruction to lift the pressure sensitivity of the sub-region to be corresponded according to the determined adjustment range, and if the lowering instruction is generated, the electronic device may execute the lowering instruction to lower the pressure sensitivity of the sub-region to be corresponded according to the determined adjustment range.
The electronic device adjusts the pressure sensitivity of the target adjustment region so that the adjusted pressure sensitivity of the target adjustment region is restored to the reference pressure sensitivity as much as possible. And since the pressure sensitivity of the target adjustment region is restored to the reference pressure sensitivity, the pressure sensitivities of the respective sub-regions in the target adjustment region substantially tend to be uniform, thereby facilitating the user's operation.
In the embodiment of the present invention, since the target adjustment region may include one or more sub-regions, if the target adjustment region includes a plurality of sub-regions, two of the sub-regions may be referred to as a first target adjustment region and a second target adjustment region, respectively. Since the change values of the capacitance values of the first target adjustment region and the second target adjustment region may be the same or different, the adjustment values of the pressure sensitivity determined by the electronic device for the first target adjustment region and the second target adjustment region may be the same or different. If the determined adjustment values of the first target adjustment area and the second target adjustment area are the same, the electronic device may respectively adjust the pressure sensitivities of the first target adjustment area and the second target adjustment area according to the same adjustment value, and if the determined adjustment values of the first target adjustment area and the second target adjustment area are different, the electronic device may respectively adjust the pressure sensitivities of the first target adjustment area and the second target adjustment area according to different adjustment values.
The foregoing embodiment is directed to the electronic device adjusting the pressure sensitivity of the target adjustment region so that the adjusted pressure sensitivities are the same, and the following describes a manner in which the electronic device adjusting the pressure value corresponding to the pressure sensitivity of the target adjustment region so that the adjusted pressure sensitivities are the same.
The electronic device responds only when the pressure applied to the touch screen by the user, which is sensed by the electronic device, needs to reach a pressure value corresponding to the pressure sensitivity of the touch screen. For example, if the sensitivity of the touch screen is 1, the pressure value corresponding to the pressure sensitivity is 1, and the electronic device itself should respond to 1 when the user applies the pressure 1, but if the pressure sensitivity of the touch screen is 2 and the pressure value corresponding to the pressure sensitivity is 2, the electronic device may respond to 1 only if the user needs to apply the pressure 2, it is known that the pressure sensitivity may correspond to the pressure value, and the pressure sensitivity of the electronic device for adjusting the pressure sensing area of the touch screen may be the pressure value corresponding to the pressure sensitivity for adjusting the corresponding area.
In a specific implementation, the electronic device may be provided with a pressure sensing element such as a pressure sensor, for example, the electronic device may be provided with several pressure sensors, each of which may cover a part of the pressure sensing area of the touch screen, for example, 4 pressure sensors. The electronic device may determine an area covered by each pressure sensor as a target adjustment area, and the pressure sensitivity of the electronic device in the adjustment target adjustment area may be the sensitivity of the pressure sensor corresponding to the adjustment target adjustment area.
The electronics can adjust the sensitivity of the pressure sensor by adjusting a pressure threshold of the pressure sensor. Specifically, the pressure sensor may store a preset pressure threshold, where the pressure threshold may be a pressure value corresponding to a reference pressure sensitivity of the touch screen, and the reference pressure sensitivity may be a pressure sensitivity of the touch screen after pressure calibration when the touch screen leaves a factory, and for example, the pressure threshold corresponding to the reference pressure sensitivity may be stored after the touch screen leaves the factory and pressure calibration is performed, which is the preset pressure threshold. The electronic device may preset a corresponding relationship between the pressure sensitivity and the pressure value, determine the pressure sensitivity of the target adjustment region in the electronic device, and determine the pressure value corresponding to the pressure sensitivity of the target adjustment region by querying the corresponding relationship, so that the pressure value may be adjusted to the pressure threshold of the pressure sensor set in the target adjustment region. For example, if the electronic device needs to adjust the pressure sensitivity of the target adjustment region, the electronic device may adjust a pressure threshold stored in a pressure sensor disposed in the corresponding target adjustment region, the electronic device may obtain the current pressure sensitivity of the target adjustment region, obtain a pressure value of the target adjustment region according to the corresponding relationship between the pressure sensitivity and the pressure value and the current pressure sensitivity of the target adjustment region, and write the pressure value into the pressure sensor disposed in the corresponding target adjustment region as a new pressure threshold, so that the electronic device may perform the same response as before the adjustment if the sub-region receives the same pressure as before the adjustment after the adjustment.
In the embodiment of the invention, when the pressure sensitivity of the pressure sensing area needs to be adjusted, the target adjustment area can be determined, and the adjustment value of the target adjustment area can be obtained, so that the pressure sensitivity of the target adjustment area can be adjusted according to the adjustment value, and thus, even if the pressure sensitivity of the touch screen is changed, the pressure sensitivity can be adjusted by the method provided by the embodiment of the invention, so that the false response caused by the change of the pressure sensitivity of the touch screen is avoided as much as possible, the false response rate of the electronic equipment is reduced, the pressure sensitivity can be automatically adjusted, and the intelligence of the electronic equipment is higher.
The following describes the apparatus provided by the embodiment of the present invention with reference to the drawings.
Referring to fig. 2, based on the same inventive concept, an embodiment of the present invention provides an electronic device, which may include a touch screen 201 and a processor 202. Fig. 2 illustrates the electronic device as a mobile phone, but is not limited thereto. In addition, since the processor 202 is actually disposed inside the handset, it should not be visible, and is therefore illustrated in fig. 2 by a dashed box. A pressure sensitive area may be included on the touch screen 201. The processor 202 may be configured to execute a control instruction for instructing to adjust a pressure sensitivity of a pressure sensing area of the touch screen, determine a target adjustment area from the pressure sensing area, the target adjustment area being a partial area of the pressure sensing area, obtain an adjustment value for the target adjustment area, and adjust the pressure sensitivity of the target adjustment area based on the adjustment value.
Optionally, the target adjustment area may be one or more.
