Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. 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 dynamic display area adjustment method 10, which is applied to a mobile terminal, where the mobile terminal includes a touch screen and an acceleration sensor, and the touch screen is used for displaying content and receiving a touch signal of a user. In practical applications, some areas of the touch screen may receive a touch signal of a user at any time, and respond according to the touch signal, for example, corresponding function buttons may be displayed on the touch screen, and the user may click the function buttons by touch to implement corresponding functions. And under the condition that a user holds the mobile terminal, the areas on the two sides are close to the positions held by the hands of the user, particularly in the mobile terminal with the curved screen, the curved touch screen extends to the side face of the mobile terminal, and the side area can also display content and receive touch signals of the user. In some emergency situations, the user may suddenly increase the grip area or inadvertently touch the area near the grip position, resulting in a malfunction situation. To solve the above problem, the method 10 for dynamically adjusting a display area provided in 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, reducing the area of the display area 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 the large screen, especially the curved screen, expands the area of the content displayed by the mobile terminal on one hand, and enables almost the whole front and side surfaces of the device to be in the area capable of inducing touch operation on the other hand, so that the user is easy to generate misoperation.
When the mobile terminal suddenly shakes or shakes violently, a user may inadvertently hold the mobile terminal tightly, and a palm or a finger touches the screen or a middle part of the screen, which may cause a false touch and unnecessary operations, affecting user experience. Therefore, in the embodiment of the disclosure, after the mobile terminal is detected to be in a sudden motion state, the mobile terminal reduces the display area, and no function button or instruction area for receiving the touch signal of the user is displayed at the edge of the touch screen, so that the touch signal is not triggered even if the user touches the edge or the middle part of the screen, and the touch signal is not displayed and received on the screen under normal conditions, thereby flexibly preventing the false touch operation caused by the stress reaction of the user at the moment, and improving the user experience.
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 divided acceleration of each dimension, a sudden change in the direction of movement may also cause the display area to shrink.
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 reducing the display area towards the center of the touch screen.
In this embodiment, changing the area of the display area may be implemented by changing the shape of the area, and the display area is reduced from being full of the full screen to the center of the screen according to a certain ratio, or even reduced to a point, so that the edge portion of the screen, or even the full screen, has almost no display content, and no meaningful touch signal is generated even if the user touches the non-display portion, thereby reducing the probability of misoperation caused by actions such as gripping and scratching of the user, or completely avoiding the occurrence of misoperation.
Under normal conditions, a user usually touches only a small part of the edge in a normal holding mode, and when an emergency occurs, such as collision, sudden stop or acceleration, the user may not autonomously grip the mobile phone, and may also have a situation that fingers slide, which may cause a larger range of touches, thereby causing misoperation, such as opening an application or pressing some operation buttons, sometimes causing the mobile terminal to mistakenly send information, confirm an order or open many application programs, seriously affecting the operation of the user, and causing user annoyance.
Therefore, when the emergency situation is detected, as shown in fig. 2, the display area 111 of the touch screen 11 of the mobile terminal is reduced toward the center of the touch screen 11. Even if the user touches or clicks the non-display portion of the screen at this time, no meaningful operation instruction is generated, and the above can be avoided.
In an embodiment, as shown in fig. 3, before step S11, the method 10 for dynamically adjusting a display area may further include: step S14: acquiring preset settings of a display area, wherein the preset settings comprise initial settings of a mobile terminal or user-defined settings; the display area dynamic adjustment method 10 may further include: step S15: and if the mobile terminal does not have sudden motion at present, keeping the display area according to preset settings.
In this embodiment, the size of the display area of the touch screen may be set when the touch screen leaves the factory, the user may also set the relevant parameters by user-defining through the interactive interface, the area of the area may be set to a corresponding size according to the user's requirement, and the dynamic adjustment of the area is performed on the basis of the preset setting of the display area. When the user uses the display device normally or returns to normal from sudden movement, the display area keeps the initial area, so that the normal use of the user is ensured.

In one embodiment, the acceleration data includes component accelerations of the mobile terminal in three dimensions, including an x-axis component acceleration, a y-axis component acceleration, and a z-axis component acceleration.
In an embodiment, the motion analysis unit 120 is configured to: 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 an embodiment, the motion analysis unit 120 is configured to: 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.
