Detailed ways

Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements.

Please refer to FIG. 1 , which describes the workflow of an embodiment of the method for operating a touch screen with one hand based on a mobile terminal in the present invention. As shown in Figure 1, the following steps are included:

Step S101, setting the size and position of the touch area;

Specifically, as shown in FIG. 2, step S101 specifically includes:

Step S1011, setting left-hand operation and right-hand operation;

Step S1012, respectively setting the size of the touch area during left-hand operation and right-hand operation; the size of the touch area can be set by the user at will, of course, it can also be set according to the user's age group or usage habits, such as when the user is a child, you can set Smaller size touch area, when the user is an adult, set a larger size touch area, or the user is used to operating in a very small area, then you can set a smaller size touch area;

Step S1013, respectively setting the position of the touch area during left-hand operation and right-hand operation; wherein the position of the touch area can be any area on the touch screen, of course, for the convenience of user operation, it is generally set at the lower left or right corner of the touch screen, such as When the user is accustomed to right-handed operation, the position of the touch area can be set at the lower right corner of the touch screen so that the user can conveniently operate the touch area. Specifically: assuming that the size of the touch screen is x0*y0, establish a rectangular coordinate system ( As shown in Figure 3), the upper left corner of the touch screen is the origin A (0, 0), the lower right corner is point D (x0, y0), the lower left corner is point C (0, y0), and the upper right corner is point B (x0 , 0), if the size of the touch area is set to a*b, and the position of the touch area is the lower right corner of the touch screen, then the position of the touch area in the Cartesian coordinate system is: the D' coordinate of the lower right corner of the touch area The same coordinates as point D, the upper left corner of the touch area is point A' (x0-a, y0-b), the lower left corner of the touch area is point C' (x0-a, y0), the upper right corner of the touch area Point B'(x0, y0-b), at this time a point coordinate M'(x1, y1) in the touch area corresponds to point M(x2, y2) on the touch screen, where x2=(x1-x0+ a)*x0/a, y2=(y1-y0+b)*y0/b, M'(x1, y1) is the coordinate of the first point, M(x2, y2) is the coordinate of the second point, a< x0, b<y0;

Step S1014, exiting the setting of the one-handed operation mode;

Step S102, turn on the one-handed operation mode switch to enter the one-handed operation mode; an option will be added in the settings, and then a button will also be added in the shortcut switch (in the drop-down list of the status bar or the desktop widget) as one-handed operation The mode switch is similar to the switch of wifi and bluetooth, and the system will add a variable to save the state of the one-handed operation mode switch;

Step S103, select left-handed operation or right-handed operation in the one-handed operation mode;

Step S104, receiving the touch operation input in the touch area and obtaining the coordinates of the first point of the touch operation; for example: when the left hand operation is selected, the positions of the touch area and the touch screen in the Cartesian coordinate system are shown in Figure 4, if the user Perform a touch operation on a certain point N' in the touch area, and use this point as the first point, then the mobile terminal receives the touch operation and obtains the coordinates N' (x3, y3) of the first point; it should be noted that the touch area For transparent display, users can clearly see the application interface on the entire touch screen. After entering the one-handed operation mode, the user can choose to mark the touch area with a dotted frame (as shown in Figure 4) to deepen the user's understanding of the touch screen. The impression of the area, when the user is used to one-handed operation, he can choose to remove the dotted frame to make the interface more beautiful; in addition, when entering the one-handed operation mode, only the touch area is the operable area, and the mobile terminal only controls the area within the touch area. Touch operations are processed, and touch operations in other areas are shielded, so that user misoperations can be avoided;

Step S105, convert the coordinates of the first point in the touch area to the coordinates of the second point on the touch screen according to the coordinate mapping relationship; as shown in Figure 3, the upper left corner of the touch screen is the origin A (0,0), and the lower right corner is the point D (x0, y0), point C (0, y0) in the lower left corner, and point B (x0, 0) in the upper right corner, set the size of the touch area to a*b, and the position of the touch area is the lower left corner of the touch screen , that is, the coordinates of point C' in the lower left corner of the touch area are the same as those of point C, the lower right corner of the touch area is point D'(a, y0), and the upper left corner of the touch area is point A'(0, y0-b ), the upper right corner of the touch area is point B'(a, y0-b), at this time the first point coordinate N'(x3, y3) in the touch area corresponds to the second point coordinate N(x4 , y4), where x4=x3*x0/a, y4=(y3-y0+b)*y0/b, that is, the touch screen and the touch area are mapped point-to-point, and the touch operation in the touch area can be mapped as The operation on the entire touch screen realizes the operation of the entire touch screen in a small touch area, which is convenient for the user to operate the large-screen mobile terminal with one hand and improves the user experience;

Step S106, highlighting the coordinates of the second point; as shown in Figure 4, highlighting the coordinates N(x4, y4) of the second point, that is, at the position of the coordinates N(x4, y4) of the second point in the form of a bright spot Display, when the coordinates of the second point are highlighted, it can help the user to confirm whether the operation in the touch area is correct to avoid user misoperation. At the same time, after multiple touch operations in the touch area and correspondingly highlight the touch screen After the corresponding position is displayed, it is beneficial for the user to form an overall area corresponding relationship, improve the operation accuracy, and avoid user misoperation; of course, "highlight the second point coordinates" can also be controlled by a switch, and the user can choose not to display it. Since the operation in the one-handed operation mode is generally relatively simple, such as turning pages or selecting buttons, in this case the touch screen interface is not too complicated, so there is no need for particularly precise operations. After the conversion behavior, the probability of misoperation will be very small;

It should be noted that in this embodiment, a "confirm" operation can also be added. After the coordinates of the second point are highlighted, if the user wants to operate the area, then select "confirm" to enter the next operation. On the contrary, if the user If you find that it is not an area you want to operate, you don’t need to choose “OK”. After a set time, the mobile terminal will block the user’s touch operation, and will not deal with the touch screen accordingly. Canceling the opportunity of touch operation is more conducive to improving the accuracy of user operation;

Step S107 , according to the touch operation and the coordinates of the second point, corresponding processing is performed on the mobile terminal; for example, controlling the mobile terminal to answer a call or performing a page turning operation on a running application program.

It should be noted that, in the method for operating a touch screen with one hand based on a mobile terminal in the present invention, the touch operation is a short press, a long press or a slide, wherein the slide includes continuous slide (such as page turning operation) and non-continuous slide (such as performing an operation on the interface). Zooming operation), when zooming the interface, you need to slide at different positions on the touch screen at the same time, which is called discontinuous sliding. When the touch operation is a short press or a long press, the coordinates of the first point of the touch operation and the corresponding second The point coordinates are the coordinates of the touch point (as shown in Figure 3 and Figure 4). When the touch operation is continuous sliding, the touch operation corresponds to multi-point coordinates, and the multi-point coordinates constitute the area F' corresponding to the touch operation, and the area F 'corresponds to the area F on the touch screen, and the area F' is in one-to-one correspondence with the coordinate points in the area F. At this time, the coordinates of the first point include the coordinates of all points in the area F', and the coordinates of the second point include the coordinates of the area F. The coordinates of all points within, as shown in Figure 5, when the touch area is located in the lower right corner of the touch screen, area F' includes points 1', 2', 3'...n', area F includes points 1, 2, 3...n, the coordinates of the first point include the coordinates of points 1', 2', 3'...n', and the coordinates of the second point include the coordinates of points 1, 2, 3...n, where the points 1' has coordinates of 1' (a1', b1'), point 2' has coordinates of 2' (a2', b2') ... point n' has coordinates of n' (an', bn'), point 1 has coordinates of 1 (a1, b1), the coordinates of point 2 are 2 (a2, b2) ... the coordinates of point n are n (an, bn), a1=(a1'-x0+a)*x0/a, b1=(b1 '-y0+b)*y0/b, a2=(a2'-x0+a)*x0/a, b2=(b2'-y0+b)*y0/b...an=(an'-x0 +a)*x0/a, bn=(bn'-y0+b)*y0/b, that is, when the touch operation is continuous sliding, there is a multi-point mapping between the first point coordinates and the second point coordinates, when the touch operation When it is non-continuous sliding, the coordinates of the first point and the second point of the touch operation are still multi-point mapping, and the coordinate mapping relationship between each point is the same as the coordinate mapping relationship when the touch operation is long press or short press .
