Example 1
According to fig. 3, the screen is divided into five areas, a, B, C, D, E, illustrated as resolution 800 × 480. Area A: coordinates in the upper right corner (0, 0), left in the lower right corner (0+ a, 0+ b); b area range: coordinates in the upper right corner (800-a, 0), left in the lower right corner (800, 0+ b); c area range: coordinates of the upper right corner (800-a, 480-b), left of the lower right corner (800, 480); d area range: coordinates in the upper right corner (0, 480-b), left in the lower right corner (0+ a, 480); e, area range: coordinates in the upper right corner (0+ a, 0+ b), left in the lower right corner (800-a, 480-b);

Five areas A, B, C, D and E divided by the screen area have no specific significance, and only five areas including the upper left corner, the upper right corner, the lower left corner and the center of the screen are marked.
For the origin offset, since five areas A, B, C, D and E define a range, a larger offset can be covered, and a specific coordinate point is not limited.
According to fig. 5, for the coordinate origin position change, as the origin is changed from the upper left corner shown in fig. 3 to the lower right corner shown in fig. 5, the area a in fig. 5 corresponds to the area C in fig. 3, the area B in fig. 5 corresponds to the area D in fig. 3, the area C in fig. 5 corresponds to the area a in fig. 3, the area D in fig. 5 corresponds to the area B in fig. 3, and the area E in fig. 5 is consistent with the area 1 in fig. 3.
Description of the principle of software validation of trigger rules:
using a stack with the capacity of 8 to store coordinate point data, after clicking a screen to acquire coordinates, firstly judging whether the coordinate points belong to five areas of A, B, C, D and E, if the coordinate points belong to the defined area, recording the data into the stack, when the stack is full, judging whether the recorded coordinates of the stack top belong to the area E, and then checking whether the difference value between the click time of the coordinate of the stack top and the click time of the coordinate of the stack bottom is less than the defined time 8 s.
It is next determined whether the click sequence complies with the triggering rules illustrated in FIG. 4.
Data structure in the stack: x coordinate, y left, time clicked, area clicked.
The screen calibration trigger verification logic is as follows:
as shown in fig. 2, the trigger screen calibration logic determines that the process is started:
prepare for calibration trigger logic verification.
The first step is as follows: judging whether the position mark of the stack top is an area 'E', if not, returning to the beginning of the process; if so, the second step is entered.
The second step is that: checking whether the interval between the stack top clicking time and the stack bottom clicking time is less than 8s, and if the interval is more than 8s, returning to the beginning of the process; if so, go to the third step.
The third step: it is verified whether the sum of the first 4 position flags on the stack is equal to the sum of the 4 th to 7 th position flags and is equal to 266. If not, returning to the beginning of the flow; if yes, the fourth step is entered.
The fourth step: verifying whether the position mark in the stack is symmetrical by taking the 4 th node as a center, and if not, returning to the beginning of the process; if yes, screen calibration is triggered, and the process is ended.
