 The processing unit 10 is configured to invoke and execute the touch screen scrolling control system 11 to implement scrolling control of the touch screen display system 12 of the data processing device 1.

 As shown in FIG. 3, it is a functional block diagram of the touch screen scrolling control system 11 of FIG. The touch screen scrolling control system 11 includes a parameter setting module 110, a trajectory computing module 111, and a scrolling control module 112.

 The parameter setting module 110 is configured to acquire a trajectory operation parameter for performing scrolling control on the touch screen display system 12. The parameter setting module acquires the trajectory operation parameter according to the following steps: The default saved trajectory operation parameter, and when the first setting or need to be reset, provides a selection item to set the trajectory operation parameter.

In other embodiments of the present invention, the trajectory operation parameter includes any applicable one that can be used for the touch screen display system 12 The parameters for scrolling control.

Referring to FIG. 4 of the embodiment, the sliding distance range, the sliding time range, and the continuous scrolling range correspond to each other, for example, n0 < A nl (sliding distance range) and tl < B < Tl (sliding time range) corresponding continuous scrolling range It is 0.1 area to be scrolled (ie: continuous scrolling range is 0.1 X area to be scrolled;), where there is no necessary inclusion and cross relationship between each sliding time range, for example, tl < B T1 and t2 < B T2 There is no inevitable existence and inclusion The system does not necessarily have a range cross relationship, and those skilled in the art can set according to the performance requirements of the touch screen display system.

 The trajectory computing module 111 is configured to detect a continuous touch event through the touch screen display system 12, and acquire touch track data according to the detected touch event. In this embodiment, the continuous touch event refers to a continuous touch behavior event, that is, the interruption of the touch behavior cannot occur between the start of the touch behavior and the end of the touch behavior; the touch track data includes starting to slide. The position, the end of the sliding position, the sliding distance, and the sliding time.

 The trajectory computing module 111 is further configured to analyze whether the continuous scrolling is required according to the acquired touch trajectory data and the set trajectory operation parameters.

 In this embodiment, the trajectory computing module 111 determines whether the continuous trajectory is required by analyzing whether the acquired touch trajectory data satisfies the set trajectory operation parameter. For example, when the sliding distance is in the range of n0 < A nl and the sliding time is in the range of tl < B T1, the trajectory computing module 111 determines that continuous scrolling is required.

 The trajectory computing module 111 is further configured to determine an effective continuous scrolling direction and range according to the acquired touch trajectory data and the set trajectory operation parameters when continuous scrolling is required.

 In the present embodiment, the trajectory operation module 111 determines the direction of the continuous scrolling by performing quadrant division on the sliding direction. The area to be scrolled 1002 is equally divided into quadrant regions according to the coordinate system. As shown in FIG. 5, in the plane rectangular coordinate system XOY, the area to be scrolled ABCD is equally divided into four quadrant regions, namely AOB, BOC, COD, DOA. Wherein, the origin 0 represents the position at which the sliding starts, and the line segment is made according to the position where the sliding starts and the position where the sliding ends, and the direction of the continuous scrolling is determined by analyzing which quadrant region of the straight paragraph into the division, for example, the straight line segment 01, 01 falls. Into the quadrant DOA, the determined continuous scrolling direction is the positive axis direction of the Y-axis.

The effective continuous scrolling direction refers to a direction in which the area to be scrolled can be scrolled. When the area to be scrolled can only scroll in one coordinate axis direction, if the determined continuous scrolling direction is the direction of the other coordinate axis, the trajectory operation module 111 determines that the determined continuous scrolling direction is invalid. Scrolling direction, no continuous scrolling operation. For example, when scrolling only in the positive and negative directions of the Y-axis, if the determined continuous scrolling direction is the positive or negative axis direction of the X-axis, the trajectory calculation module ill determines that the determined continuous scrolling direction is invalid. Scrolling direction, no continuous scrolling operation.

 There are many ways to determine the direction of continuous scrolling.

In this embodiment, the trajectory operation module 111 determines whether continuous scrolling is required by analyzing whether the acquired touch trajectory data satisfies the set trajectory operation parameter.

 When continuous scrolling is required, the following steps S16, S17, and S18 are performed, or, when continuous scrolling is not required, the process proceeds to the following step S15.

 In step S15, the scroll control module 112 scrolls in real time according to the detected touch event.

 In step S16, the trajectory operation module 111 determines the direction and range of the continuous scrolling according to the acquired touch trajectory data and the set trajectory operation parameters.
