Referring to fig. 1, the present application provides a method for controlling a mouse pointer, which specifically includes the following steps:
step one: acquiring a mouse pointer, analyzing the operation of the mouse pointer, and performing secondary analysis processing on the mouse pointer according to the operation time to obtain a secondary analysis result, wherein the secondary analysis result comprises the following steps: the specific way of generating the secondary analysis result is as follows:
s1: the mouse pointer is marked as a target object, whether the target object has clicking operation is judged, if the target object has clicking operation, the target object is marked as an object to be analyzed, otherwise, if the target object does not have clicking operation, the target object is marked as a normal object;
in combination with actual scene analysis, when the operation is performed by using the mouse under normal conditions, the mouse needs to be clicked, if the mouse pointer does not have any click, the mouse pointer does not need to be analyzed, and if the mouse pointer has click, the mouse pointer is further analyzed.
S2: and then acquiring the click time length of the object to be analyzed, and comparing the acquired click time length with a preset value, if the click time length exceeds the preset value, processing is not needed and an unprocessed signal is generated, otherwise, if the click time length does not exceed the preset value, processing is needed and a processed signal is generated. It should be noted that, when the mouse is used for operation, if the operation duration is short, the selection action reflected by the mouse is described, and if the operation duration is long, the dominant action reflected by the mouse is described.
In combination with the analysis of the actual application scene, when the mouse is used for drawing on the drawing board, the action of the mouse is reflected as a dominant action, and when the mouse is used, the movement track of the mouse generates a line, so that an image is formed by the line, the clicking time of the mouse in the process is long, but when the mouse is used for selecting, the simple clicking action can be completed, and the mouse is reflected as a selecting action.
Step two: analyzing paths in the motion process of the object to be analyzed, generating corresponding motion tracks, judging whether the object to be analyzed needs to be regulated and controlled according to the motion tracks, and generating regulation and control results, wherein the regulation and control results comprise: the specific mode of generating the regulation result is as follows:
p1: acquiring an operation point of an object to be analyzed, recording the operation point as a starting point, acquiring a real-time position of the object to be analyzed, taking the real-time position as a real-time end point, and generating a motion track according to the distance between the starting point and the real-time end point; it should be noted that, when the mouse pointer moves, the position where the clicking operation is generated is recorded as a starting point, and when the subsequent mouse pointer moves, the position where the mouse pointer changes in real time is recorded as a real-time end point.

if Q is more than or equal to Qy, the track segment exceeds the preset value and generates a normal signal at the same time, and the normal signal is not regulated and controlled, otherwise, if Q is less than Qy, the track segment does not exceed the preset value and generates a regulating signal at the same time. It should be noted that, the specific value of the preset value is set by the operator, and the preset value is a judgment standard for measuring whether to adjust.
In combination with the analysis of the actual situation, when the mouse is actually used for drawing the straight line, the state that the straight line cannot be maintained is also existed when the mouse is used for drawing the straight line further because the mouse operated by the human operator cannot always maintain the straight line state, and under the condition that the standard straight line icon is not drawn, but the straight line cannot be maintained, the mouse pointer is required to be regulated and controlled, meanwhile, the display by the mouse is possibly different from the actual situation operated by the human operator, and the drawing of the straight line cannot be further maintained.

It should be noted that, firstly, the track segment with the smallest difference between the segments is selected, the track segment meeting the requirement is obtained by calculating the difference between the tail end point of the previous segment and the head end point of the next segment of the adjacent track segment, then the sum of the height difference of the two track segments is calculated, and finally the average value is calculated and obtained as the adjustment standard.
Combining with actual situation analysis, when a single difference result is obtained, only a group of identical height differences are shown, the group of identical height differences are used as regulation and control standards, then the position of a real-time mouse pointer is obtained, the height of the ordinate is calculated, whether the height of the ordinate is identical to the regulation and control standards is judged, regulation is not needed for the identical height, otherwise, the difference between the two is calculated to generate regulation and control information, meanwhile, when a difference result without the single difference is obtained, a track section corresponding to a plurality of identical height differences is shown, at the moment, the generation time of different track sections is obtained, and the track section closest to the current time node is selected as standard to generate the regulation and control information.
Step four: and outputting the acquired regulation and control information to a control end, and regulating and controlling the mouse pointer by the control end through an operation driving program.
In combination with actual situation analysis, after the control end acquires the regulation and control information, the driver program can automatically lock the mouse transversely, namely, the track generated when the mouse pointer is utilized to move is a straight line, and the mouse pointer can not remove the locking until the mouse pointer stops clicking, so that the drawing of a complete straight line can be ensured.
Some of the data in the above formulas are numerical calculated by removing their dimensionality, and the contents not described in detail in the present specification are all well known in the prior art.
The above embodiments are only for illustrating the technical method of the present invention and not for limiting the same, and it should be understood by those skilled in the art that the technical method of the present invention may be modified or substituted without departing from the spirit and scope of the technical method of the present invention.
