The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The embodiment of the disclosure provides a method 10 for dynamically adjusting a false touch prevention area, which is applied to a mobile terminal, where the mobile terminal includes a touch screen and an acceleration sensor, the mobile terminal is provided with the false touch prevention area for preventing a user from making a false touch to cause an unnecessary operation, the false touch prevention area is generally arranged at an edge of the touch screen of the mobile terminal and is generally close to a position where the user holds the mobile terminal by a hand, and especially in the mobile terminal with a curved screen, the touch screen with the curved surface extends to a side surface of the mobile terminal, so that a side portion of the touch screen is often set to be the false touch prevention area in a screen locking state or other states, and a touch signal is ignored in the false touch prevention area, that is, even if the user touches the false touch prevention area of the touch. The false touch prevention area is used for flexibly responding to the user operation in a normal receiving state and preventing the false touch operation caused by sudden movement, and the mobile terminal can be a mobile phone and other devices. Therefore, the method 10 for dynamically adjusting the false touch prevention area provided by the embodiment of the present disclosure, as shown in fig. 1, includes steps S11-S13:
step S11: and acquiring acceleration data output by the acceleration sensor.
An acceleration sensor is a sensor that is capable of measuring acceleration, sensing acceleration and converting it into a usable output signal. The damper is generally composed of a mass block, a damper, an elastic element, a sensitive element, an adjusting circuit and the like. In the acceleration process, the acceleration sensor obtains an acceleration value by measuring the inertial force borne by the mass block and utilizing a Newton's second law. Common acceleration sensors include capacitive type, inductive type, strain type, piezoresistive type, piezoelectric type, and the like, according to different sensing elements of the acceleration sensor. The principle of acceleration sensors is newton's second law, i.e. the law of acceleration, i.e. the balance of forces, a (acceleration) being F (inertial force)/M (mass), most acceleration sensors operating according to the principle of the piezoelectric effect. The so-called piezoelectric effect is "the phenomenon that external force applied to the crystal for heteropolar crystals without symmetry centers changes the polarization state of the crystal in addition to deforming the crystal, and establishes an electric field inside the crystal, and the medium is polarized due to mechanical force action is called positive piezoelectric effect". The acceleration sensor utilizes the characteristic that the crystal is deformed due to acceleration in the acceleration sensor. Since this deformation generates a voltage, the acceleration can be converted into a voltage output by simply calculating the relationship between the generated voltage and the applied acceleration.
In an embodiment, the acquired acceleration data may be the partial accelerations of the mobile terminal in three dimensions, that is, an x-axis partial acceleration, a y-axis partial acceleration, and a z-axis partial acceleration, where the x-axis partial acceleration may correspond to the width direction of the mobile terminal, the y-axis partial acceleration may correspond to the length direction of the mobile terminal, and the z-axis partial acceleration may correspond to the thickness direction of the mobile terminal. The acceleration data can be stored in a memory buffer area or other external memories and arranged in a logic structure such as a queue or a stack according to the time sequence, and the mobile terminal can read the data according to the requirement and determine the motion state by judging the size change of the data.
Step S12: and judging whether the mobile terminal has sudden motion currently or not according to the acceleration data.
When the mobile terminal suddenly shakes or shakes sharply, for example, in a bus, the speed of the vehicle suddenly changes, such as suddenly stops or accelerates, and the acceleration data output by the acceleration sensor will change greatly. And reading acceleration data output by the acceleration sensor, and comparing the data at the front moment and the rear moment so as to detect whether the mobile terminal suddenly changes from static or gentle motion to high-speed motion.
Step S13: and if the mobile terminal is suddenly moved at present, increasing the area of the false touch prevention area positioned at the edge of the touch screen.
At present, mobile terminals increasingly adopt large screens, especially curved screens, to improve the operation experience of users. The curved screen is a display screen made of flexible plastic and is mainly realized by an OLED panel. Compared with a straight screen, the curved screen has better elasticity and is not easy to break. When the curved-surface screen is used for a mobile terminal, the curved design of the curved-surface screen is beneficial to holding, the curved-surface screen is better fitted with the palm radian, the distance of the thumb touching the screen when the screen is operated by a single hand is reduced, and the experience of transverse screen-crossing operation under a large-size screen is promoted. The curves may provide better privacy of information to the handset holder, for example, a person sitting next may not be able to see what is displayed on the screen of the device. The application of a large screen, especially a curved screen, expands the area of the content displayed by the mobile terminal on one hand, and on the other hand, almost the whole front and side surfaces of the device are in the area capable of inducing touch operation, so that a user is easy to generate misoperation.
When the mobile terminal suddenly shakes or shakes violently, a user can hold the mobile terminal tightly without self, a palm or a finger touches the edge of the screen or the middle part of the screen, and unnecessary operation is generated due to mistaken touch, so that user experience is influenced. After the sudden motion state of the mobile terminal is detected, the mobile terminal increases the false touch prevention area, so that false touch operation caused by stress reaction of the user at the moment can be flexibly prevented, and the user experience is improved.
In one embodiment, step S12 may include: if the difference value obtained by subtracting the partial acceleration of the same dimension at the previous moment from the partial acceleration of any dimension at the current moment is larger than a first threshold value, or if the difference value obtained by subtracting the total acceleration at the previous moment from the total acceleration at the current moment is larger than a second threshold value, judging that the mobile terminal suddenly moves; wherein the total acceleration is the vector sum of the component accelerations of the three dimensions.
In this embodiment, the degree of the sudden change of the acceleration is determined by a difference between the front time and the rear time, and when the difference is greater than the first threshold, it is determined that the mobile terminal has suddenly moved. This case does not only consider that the mobile terminal suddenly moves from a standstill, but by detecting the component acceleration of each dimension, a sudden change in the direction of movement may also cause an increase in the area of the anti-false touch region.
In one embodiment, step S12 may include: if the partial acceleration of any dimension at the previous moment is smaller than a third threshold and the partial acceleration of the same dimension at the current moment is larger than a fourth threshold, or if the total acceleration at the previous moment is smaller than a fifth threshold and the total acceleration at the current moment is larger than a sixth threshold, determining that the mobile terminal has sudden motion; wherein the total acceleration is the vector sum of the three-dimensional component accelerations; the fourth threshold is greater than the third threshold, and the sixth threshold is greater than the fifth threshold.
In this embodiment, a short time change in acceleration from a lower value to a higher value is used to determine the occurrence of sudden motion. This case emphasizes consideration of the user's normal use smoothly to a state where a motion suddenly occurs.
In one embodiment, step S13 may include: and expanding the false touch prevention area towards the center of the touch screen.
In this embodiment, the area of the anti-false-touch region can be changed by changing the shape of the region, and the anti-false-touch region is enlarged from a position close to the edge to the center of the screen, so as to cover more parts, even the whole screen, thereby reducing the probability of false operation caused by actions of a user such as gripping and scratching, or completely avoiding the occurrence of false operation.
As shown in fig. 2, the edge of the touch screen 11 of the mobile terminal is provided with an error touch prevention area 111, a user usually touches only a small portion of the edge when holding the mobile terminal under normal conditions, and when an emergency occurs, such as collision, sudden stop, or acceleration, the user may not grip the mobile phone autonomously, and may also have a situation that fingers slide, which may cause a larger range of touch, thereby causing an error operation, such as opening an application or pressing some operation buttons, sometimes causing the mobile terminal to send information incorrectly, confirm an order, or open many application programs, which seriously affects the operation of the user, and causes user annoyance.
Therefore, as shown in fig. 3, according to the embodiment, when an emergency situation is detected, the area of the erroneous-touch prevention region 112 is enlarged by flexibly enlarging the erroneous-touch prevention region toward the center of the touch panel 11, and the area of the erroneous-touch prevention region 112 is enlarged.
In an embodiment, as shown in fig. 4, before step S11, the method 10 for dynamically adjusting a false touch prevention area may further include: step S14: acquiring preset settings of a false touch prevention area, wherein the preset settings comprise initial settings of a mobile terminal or user-defined settings; the method 10 for dynamically adjusting the anti-false touch region may further include: step S15: and if the mobile terminal does not have sudden motion at present, keeping the false touch prevention area according to preset settings.
In this embodiment, the size and the shape of the false touch prevention region of the touch screen may be set when leaving the factory, the user may also set the relevant parameters by user-defining through the interactive interface, the region area may be set to a corresponding size according to the user requirement, and the dynamic adjustment of the region area is performed on the basis of the preset setting of the false touch prevention region. When the user normally uses or returns to normal from sudden movement, the false touch prevention area keeps the initial level, thereby ensuring the normal use of the user.
