Embodiments of the invention

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

Force Touch, which refers to the generation and change of induced pressure, realizes the change of electrical data, and then generates instructions through electrical data, and finally reaches the process of indirectly implementing instructions through pressure. In various embodiments of the present invention, it is by applying the technical principle that the pressure change received by the pressure screen is converted into a change of the visual information on the pressure screen such as a graphic and transmitted to the user, and the user further judges the operation, thereby realizing Unlock the screen for this human-computer interaction process.

The basis of the implementation of the embodiment of the present invention is that the terminal device is equipped with a screen supporting pressure touch, which is simply referred to as a pressure screen, which is used to sense the coordinates of the pressure applied by the screen, the magnitude of the force, the direction of the force, the duration of the force, etc. Information; and the pressure of the pressure screen described in the embodiments of the present invention needs to be controlled within the maximum pressure range that it supports without being damaged.

In an embodiment of the invention, the pressure information received by the pressure screen is mapped to one or more visually stressed areas on the screen. According to the change of the pressure information, the display of the visual force area may also change, and the current pressure information of the user and the unlocking condition may be promptly and conveniently displayed to unlock or maintain the lock screen state, thereby completing the unlocking of the pressure screen.

In the embodiment of the present invention, it is relatively simple to receive a pressure each time the screen is subjected to multiple times. The scenario is described as an example. In the present example of the invention, the pressure screen is only subjected to pressure applied by the user at one point each time, and after pressure is applied to the pressure screen a plurality of times, the unlocking condition is finally satisfied by calculation to finally unlock the screen.

The scene in actual use may be more complicated. The pressure point of the pressure screen may be one or more at a time; for example, there are multiple stress points on the pressure screen, and the screen can be subjected to multiple pressures at the same time. The scene is equivalent to a scene in which the screen is subjected to a pressure every time and is subjected to multiple times, that is, equivalent to the scene described in the embodiment of the present invention, and the plurality of pieces of pressure information data can still be implemented according to the principle of the example of the present invention. Calculate, merge, map.

The method for unlocking the screen of the terminal provided by the embodiment of the present invention is described in detail below with reference to the accompanying drawings.

FIG. 1 is a flowchart of a method for releasing a screen lock of a terminal according to an embodiment of the present invention. As shown in FIG. 1 , the method provided in this embodiment may be performed by a terminal device configured with a pressure touch screen, and the method provided in this embodiment includes steps 101-104:

Step 101: When the pressure screen is in a lock screen state, one or more areas to be stressed are displayed on the pressure screen.

Before the step, the terminal device first reads the identifier bit data of the current lock screen state, and determines whether the pressure screen is currently in the lock screen state according to the identifier bit data, and performs execution when determining that the pressure screen is in the lock screen state. This step.

Step 102: Acquire pressure information of a user press received by the pressure screen.

Optionally, the pressure information includes: coordinate information (x, y), size information p, direction information a, and duration information t.

Step 103: Calculate the pressure information, and map the calculation result on the pressure screen to one or more visual force receiving regions.

Optionally, calculating the pressure information, and mapping the calculation result to the one or more visual force receiving regions on the pressure screen comprises: calculating the pressure information to obtain first coordinate data, and The first coordinate data is mapped on the pressure screen as a first visual force receiving area; the second visualization of mapping the first visual force receiving area of the first coordinate data mapping with the stored second coordinate data The logical region is calculated by the force region, and the third visualization after calculation is obtained. a force receiving area; storing the calculation result, and mapping the calculated third visual force receiving area on the pressure screen to the one or more visual force receiving areas.

It should be noted that, if the first coordinate data is calculated according to the pressure information obtained by the user pressing the pressure screen for the first time, the calculation result is the first coordinate data, the one or The plurality of visual force receiving regions are regions on which the first coordinate data is mapped on the pressure screen; the calculation result, that is, the first coordinate data is stored.

If the pressure information obtained by the user pressing the pressure screen for the second time is obtained, the data calculated according to the pressure information obtained by the user pressing the pressure screen for the second time can be regarded as the first coordinate data, and according to the user The coordinate data calculated by pressing the pressure information obtained by the pressure screen at a time, that is, the stored calculation result, can be regarded as the second coordinate data described in this embodiment, and in this step, the first The coordinate data is subjected to an AND operation with the stored second coordinate data, and the obtained calculation result is stored, and mapped to the one or more visual force receiving regions on the pressure screen.

In order to simplify the calculation, the visual force region obtained after a single force calculation will be mapped into a circular or an elliptical region; according to mathematical knowledge: in a plane coordinate, an elliptical region can be composed of 3 points. The coordinates are determined: the origin O, the long semi-axis end A, and the short semi-axis end B. When the distance a from the end point A of the long semi-axis of the ellipse to the origin is equal to the distance b from the end point B of the short semi-axis to the origin, the ellipse is a circle.

It is assumed that the coordinates of the three points O, A, and B are known as O(X, Y), A(X, Y), B(X, Y), respectively, where point O is the origin of the ellipse and point A is elliptical. The end point of the long semi-axis, point B is the short semi-axis end point of the ellipse, and the coordinates of points O, A, B can also be expressed as follows:

XO, YO represent the X-axis coordinate and the Y-axis coordinate of point O, respectively;

XA, YA represent the X-axis coordinate and the Y-axis coordinate of point A, respectively;

XB and YB respectively represent the X-axis coordinate and the Y-axis coordinate of point B;

Then the x and y coordinates of all points satisfying the following function are on an ellipse:

[(x-XO)cos θ+(y-YO)sin θ] ² /a ² +[(y-YO)cos θ-(x-XO)sin θ] ² /b ² =0

In the function:

XO and YO are known as the X-axis coordinate and the Y-axis coordinate of point O.

θ is the angle formed by the long-axis direction vector and the X-axis, and tan θ=(YA-YO)/(XA-XO), which can be derived from the known point coordinates;

a is the length of the ellipse long semi-axis, a = √ (XA-XO) + (YA-YO) ² , which can be derived from the known point coordinates;

b is the short semi-axis length of the ellipse, b=√(XB-XO)+(YB-YO) ² , which can be derived from the known point coordinates;

If a=b, then the x and y coordinates of all points satisfying this function are on a circle.

In summary: If the coordinates of the three points O, A, B are known, an ellipse or a circle of any position can be determined. Referring to FIG. 2, FIG. 2 is a schematic diagram of determining a circular or elliptical region by coordinates of three points O, A, and B on a plane.

In practical applications, the coordinates O(X, Y), A(X, Y), B(X, Y) of the three points O, A, and B can be calculated by the given algorithm formulas f1, f2, and f3. :

F1(x,y,p,a,t)=>O(X,Y);

F2(x,y,p,a,t)=>A(X,Y);

F3(x, y, p, a, t) => B(X, Y).

The coordinates of these three points will determine a circular or elliptical area, that is, a set of data O(X, Y), A(X, Y) generated by the calculation of the force information x, y, p, a, t. B (X, Y) is mapped to a visual force area displayed on the screen. This area can be called Area1 to determine whether the area meets the unlock condition.

If it is determined that the unlocking condition is not satisfied temporarily, the pressure is continuously detected. After the pressure screen is stressed for the second time, an area Area2 is still calculated according to the above method. In this case, the area of the first Area1 and the second Area2 need to be merged, and then the combined new area Area' is determined. To meet the unlocking conditions, the process of merging this area uses the "logical AND" calculation, namely Area1&&Area2=Area'. Referring to FIG. 3, FIG. 3 is a schematic diagram of region merging.

Step 104: Unlock the pressure screen when it is determined that the one or more visual force receiving regions completely cover the one or more to-be-stressed regions.

Optionally, after the pressure screen is unlocked, the stored calculation result is cleared, and the identifier bit data is set to a non-lock screen state.

The method provided in this embodiment will be described below with reference to examples.

First, the terminal device reads the identification bit data of the current lock screen state, and determines whether the screen lock screen state is currently; if the screen lock screen state is currently, one or more areas to be stressed are displayed on the screen; and the screen is detected. The pressure information of the secondary stress.

4 is a schematic diagram of a region to be stressed displayed on the pressure screen when the terminal enters the lock screen state, as shown in FIG. 4, at this time, a hexagonal area to be subjected to force is displayed on the pressure screen, and the screen is not subjected to any pressure. If the force area of the screen completely covers this hexagonal area after this, the unlocking condition is satisfied.

The pressure information received each time, including the coordinates of the force point, the magnitude of the force, the direction of the force, the duration of the force, etc., are calculated and converted into a set of coordinate data, which will be mapped to one or more on the screen. The visual force area is displayed; then the set of coordinate data and the already stored set of coordinate data are combined to generate a new set of coordinate data, and the new set of coordinate data is mapped to one or more new ones on the screen. The visual force area is displayed.

5 is a schematic diagram of a visual force-receiving area of the first set of coordinate data maps displayed on the pressure screen. After the pressure information is calculated, the map is displayed as an elliptical area on the pressure screen; it is determined that the force-receiving area is not The hexagonal area to be stressed is completely covered, and the unlocking condition is not satisfied, so it is not unlocked.

It should be noted that if the pressure information coordinate data is not stored, the new coordinate data after the combined calculation is still the coordinate data corresponding to the pressure information of the current group, and the newly visualized force region mapped after the combined calculation is still the pressure. The visual force area mapped by the coordinate data corresponding to the information.

A set of new coordinate data generated after the combined calculation is stored, and according to the new set of coordinate data, refreshing and displaying the stressed area and the area to be stressed mapped after each force are used to prompt the user of the current pressure information and whether Meet the unlock conditions.

Determining whether the new set of coordinate data satisfies the unlocking condition, that is, comparing the stressed area with the area to be stressed, determining whether the stressed area completely covers the area to be stressed; if the unlocking condition has been met, the force is already applied If the area completely covers the area to be stressed, clear the display of all the stressed area and the area to be stressed, refresh the screen display to unlock, and clear the group generated by this combined calculation. New coordinate data and position the lock screen status as non-lock screen.

FIG. 6 is a schematic diagram of a visual force-receiving area of the second set of coordinate data maps displayed on the pressure screen. After the current pressure information is calculated, it is mapped to a larger elliptical area and displayed on the pressure screen.

Figure 7 is a schematic diagram of the visual force area of the two forces combined display displayed on the pressure screen. The first two pressure information are mapped to a visualized area and displayed on the screen after the combined calculation. The force areas are combined to completely cover the hexagonal area to be stressed. When the unlocking condition is met, the display of all the stressed areas and the area to be stressed is cleared, and the screen display is unlocked; the unlocked pressure screen is shown in Figure 8.
