Description

A method, system and mobile terminal for processing coordinate events reported by a touch screen

technical field

The present invention relates to the technical field of communication, and more specifically, relates to a method, a system and a mobile terminal for processing a coordinate event reported by a touch screen.

Background technique

The touch screen brings great convenience to the user's operation, but there are differences in personal use methods. Some people like to hold the mobile phone with their left hand, and some people like to hold their mobile phone with their right hand. When we use the left hand to operate the touch screen to slide, the sliding track of our finger is usually like Figure 1, and when we use the right hand to operate the touch screen to slide, the sliding track of our finger is usually like Figure 2, no matter Swipe left or right, as long as it is operated with one hand, it is often an arc. When different people swipe, the arc may be different, but the trend is definitely the same.

At present, many applications (such as Sohu News, 3G News, QQ) and other interfaces support horizontal sliding and vertical sliding operations, that is, when the finger slides up and down, the vertical content scroll bar will be operated. When the finger slides left and right, it will switch the horizontal sliding list (for example, switch from IT to sports or entertainment), as shown in Figure 3 below.

As described in Figure 1 and Figure 2, the trajectory of our one-handed operation is often an arc, that is, the coordinates have a large movement in the x-axis direction and a large movement in the y-axis direction, then when When such coordinates are reported up, sometimes it will cause such a problem: my original intention is to slide down, but the application interface actually slides horizontally (most users are more casual when sliding up and down, while horizontal operation Time is more standardized), and different applications, the situation is also different.

Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Embodiment one

Embodiment 1 of the present invention provides a method for processing a coordinate event reported by a touch screen, and this embodiment will be described in detail below with reference to the accompanying drawings.

Fig. 4 is a flow chart of the method of Embodiment 1 of the present invention. With reference to Fig. 4, the method of the embodiment of the present invention includes the following steps:

Step S101, judging whether the currently used application supports horizontal sliding list operation;

Step S102, when the application program supports horizontal sliding list operation, collect the starting point coordinates and end point coordinates of the sliding track when the user performs sliding operation on the touch screen, and do not report the end point coordinates after the collection;

Step S103, calculating the slope of the sliding track according to the starting point coordinates and the ending point coordinates;

Step S104, comparing the absolute value of the slope of the sliding track with the set value;

Step S105, when the absolute value of the slope of the sliding track is greater than the set value, modify the abscissa of the end point coordinates to the abscissa of the start point coordinates, and report the corrected end point coordinates;

Step S106, when the application layer receives the corrected coordinates of the end point, respond to vertical sliding.

In some application programs that support horizontal sliding list operations, the present invention collects the starting point coordinates and end point coordinates of the sliding track when the user performs a sliding operation on the touch screen, calculates the slope of the sliding track through the starting point coordinates and the end point coordinates, and calculates the slope of the sliding track. The absolute value is compared with the set value to determine whether the absolute value of the slope of the sliding track is greater than the set value, so as to correct and standardize the coordinates of the end point, so as to prevent the application layer from mistaking the vertical sliding operation performed by the user on the touch screen as a horizontal sliding operation , and at the same time, when these corrected and standardized coordinates are reported to the application layer, different results will not be caused by different application layer processing principles.

Embodiment two

Embodiment 2 of the present invention provides a method for processing a coordinate event reported by a touch screen, which is an improvement on the basis of Embodiment 1.

Fig. 5 is a method flow chart of the second embodiment of the present invention, referring to Fig. 5, the method of the embodiment of the present invention includes the following steps:

Step S201, preset a set value compared with the absolute value of the slope of the sliding track;

Step S202, judging whether the currently used application program supports the horizontal sliding list operation, if the application program does not support the horizontal sliding list operation, then perform step S203, and when the application program supports the horizontal sliding list operation, then perform step S204;

Step S203, do not correct the reported coordinates of the touch screen, and adopt the normal reported coordinate processing;

Step S204, collect the starting point coordinates and end point coordinates of the sliding track when the user performs a sliding operation on the touch screen, and do not report the end point coordinates after the collection;

The touch screen device can collect the coordinate data of the finger, for example, collect 2 coordinate point data, that is, the coordinates of the starting point and the end point of the sliding track, from (x0, y0) to (x1, y1), where x represents the horizontal direction and y represents the vertical direction . In addition, after the coordinate data is collected, the coordinates of the end point are not reported to the application layer, so that the application layer will not think that the sliding has ended.

Step S205, calculating the slope of the sliding track according to the starting point coordinates and the ending point coordinates;

Further, the slope of the sliding track is obtained by dividing the difference between the ordinate of the starting point and the end point by the difference between the abscissa of the starting point and the end point, that is, the slope of the sliding track is k=(y1-y0)/( x1-x0).

Step S206, comparing the absolute value of the slope of the sliding track with the set value, when the absolute value of the slope of the sliding track is greater than the set value, then perform steps S207 and S208 in sequence, and when the absolute value of the slope of the sliding track is less than When setting the value, then execute step S209 and step S210 in sequence;

Step S207, modifying the abscissa of the end point coordinates to the abscissa of the starting point coordinates, and reporting the corrected end point coordinates;

Step S208, when the application layer receives the corrected coordinates of the end point, it responds by sliding vertically;

Step S209, reporting the normal end point coordinates;

Step S210, when the application layer receives the normal coordinates of the end point, it makes a horizontal sliding response.

Step S211 , when exiting the application program that supports horizontal sliding list operation, exit the touch screen to report coordinate correction, and adopt the normal process of reporting coordinates.

For ease of understanding, let’s take a practical application as an example. For example, the application that supports horizontal sliding list operation is 3G news, and the setting value is set to 0.5. If the absolute value of the slope of the sliding track is less than the setting value 0.5, then The driver layer of the touch screen will recognize that it is a horizontal slide, and report the normal end point coordinates at this time. After receiving these coordinates, the application layer will also consider it a horizontal slide and make a corresponding response, that is, the list of horizontal slides can be switched, as shown in Figure 3 As shown, switch from IT to sports or entertainment; if the absolute value of the slope of the sliding track is greater than the set value of 0.5, the driver layer of the touch screen will be considered as vertical sliding, and the coordinates of the end point will be modified to (x0, y1). When the application layer receives When modifying the coordinates of the end point, it must be regarded as vertical sliding, so as to respond to vertical sliding, that is, to operate the vertical content scroll bar.

What needs to be explained here is that different application layers have different processing methods. For example, in Sohu News, if the slope of the sliding track is 1 (about 45 degrees in the sliding direction), it will be considered as a horizontal sliding; but NetEase For news, etc., when the slope of the sliding track is 0.5, it is considered to be a horizontal sliding. The advantage of the present invention is that the absolute value of the slope of the sliding track can be compared with the set value to judge whether the absolute value of the slope of the sliding track is greater than the set value so as to correct and standardize the coordinates of the end point. When the coordinates are reported to the application layer, different results will not be caused by different application layer processing principles.
