technical field

The invention relates to the technology in the field of computer equipment, in particular to a method for a mouse auxiliary function for drawing a straight line.

Background technique

In designing and editing office scenarios, users need to use the mouse to draw straight lines. However, the mouse drawing function is generally free to draw manually, so it is difficult to form a standard straight line for the mouse movement track. Generally, when users draw graphics, they need to use software tools to draw straight lines; when the software is not installed in the computer system, users need to download and install the software to draw straight lines, and the operation process is cumbersome. In addition, when using the software, the user cannot determine the angle deviation of the drawn straight line, which may cause large errors in engineering design or industrial design, and even bring certain hidden dangers to the subsequent project implementation.

Therefore, it is necessary to study a new technical solution to solve the above problems.

Once the determination is completed, enter the straight line processing state, and send the direction processing results of the N times of movement data to the PC; , the direction determination algorithm is:

Step 2-1: Collect movement data in X and Y directions for N times of mouse movement;

Step 2-2: Sum the movement data in the X and Y directions respectively to obtain Xsum and Ysum, and then calculate the absolute values to obtain |Xsum| and |Ysum|;

Step 2-3: Calculate the difference Diff=||Xsum|-|Ysum||;

Step 2-4: Calculate the decision factor Factor=Max (|Xsum|/2, |Ysum|/2);

In the case of (Diff>Factor), the value X or Y direction is determined, and if (|Xsum|>|Ysum|), it is determined as the X-axis linear direction, otherwise (|Ysum|>|Xsum|), it is determined is the straight line direction of the Y-axis;

In the case of (Diff<Factor), the XY direction of the value is determined, and it is necessary to further determine whether it is XY45 degrees or XY135 degrees; among them, if the polarities of Xsum and Ysum are opposite, that is, one is positive and the other is negative, then it is the XY45 degree direction, On the contrary, if Xsum and Ysum have the same polarity, that is, they are both integers or negative numbers, they are in the XY135 degree direction;

Step 3: After that, the data obtained by the user moving the mouse is corrected in the corresponding judgment direction to ensure that the data reported by the mouse is straight line data;

Step 4: Until the user releases the function button, leaves the straight line mode, and returns to the standard mouse function.

As a preferred solution, the value of N is any integer from 16 to 20.

As a preferred solution, the function buttons are provided on the mouse; or, the function buttons are independent buttons outside the mouse and keyboard.

As a preferred solution, for the data reported by the mouse, the PC correspondingly controls the display to present the mouse to draw a straight line trajectory.

As a preferred solution, when drawing straight lines in different directions, first draw straight lines in one direction, then release the function button to leave the straight line mode and return to the standard mouse function, press the function button again, and go through steps 1, 2, Step 3 and Step 4 complete the straight line drawing in the other direction.

Send the direction processing results of the N times of movement data to the PC; wherein, the direction determination algorithm is:

Step 2-1: Collect movement data in X and Y directions for N times of mouse movement;

In the case of (Diff>Factor), the value X or Y direction is determined, and if (|Xsum|>|Ysum|), it is determined as the X-axis linear direction, otherwise (|Ysum|>|Xsum|), it is determined is the straight line direction of the Y-axis;

In the case of (Diff<Factor), the XY direction of the value is determined, and it is necessary to further determine whether it is XY45 degrees or XY135 degrees; among them, if the polarities of Xsum and Ysum are opposite, that is, one is positive and the other is negative, then it is the XY45 degree direction, On the contrary, if Xsum and Ysum have the same polarity, that is, they are both integers or negative numbers, they are in the XY135 degree direction;

Step 3: After that, the data obtained by the user moving the mouse is corrected in the corresponding judgment direction to ensure that the data reported by the mouse is straight line data;

Step 4: Until the user releases the function button, leaves the straight line mode, and returns to the standard mouse function.

Preferably, in step 3, after determining the direction of the straight line, linear processing is performed on the movement data in the X and Y directions of the mouse movement. According to the four directions, the corresponding processing algorithms are as follows:

If the determined straight line direction is the X-axis direction, discard the movement data in the Y-direction, and report only the X-direction movement data to the PC, and the reported data is [X, 0];

If the determined straight line direction is the Y-axis direction, discard the movement data in the X direction, and only report the data moved in the Y direction to the PC, and the reported data is [0, Y];

If the determined straight line direction is XY45 degree direction, then use the X direction to move the data in the opposite direction, that is, -X replaces the Y direction movement data and report it to the PC, and the reported data is [X, -X];

If the determined straight line direction is XY135 degree direction, replace the Y-direction movement data with the X-direction movement data and report the data to the PC, and the reported data is [X, X].

The mouse is a two-dimensional pointing device, and the reported data includes the movement data of the X and Y axes, the data comes from the sensor of the mouse, and both X and Y are signed integers. The X-axis direction is the horizontal direction, the Y-axis direction is the vertical direction, the XY45 degree direction is the stroke direction of Chinese characters, and the XY135 degree direction is the stroke direction of the Chinese character. The function buttons are arranged on the mouse; or, the function buttons are independent buttons outside the mouse and keyboard. The data reported by the mouse is controlled by the PC to display the mouse and draw a straight line on the display.

When you need to draw straight lines in different directions, first draw a straight line in one direction, then release the function button to leave the straight line mode and return to the standard mouse function, press the function button again, and go through steps 1, 2, 3, and 4 again.

Moreover, the mouse device is provided with a mouse sensor to feed back mouse movement data.

The function key is the function key for the mouse to enter the line drawing mode, and the function of the mouse line drawing mode is provided on the embedded software. This function realizes the function of drawing a trajectory of the mouse along a straight line by processing normal mouse sensor data. Users can use the function keys to switch between the straight line drawing mode and the free movement mode.

When the function button is not pressed, the mouse is in a standard state. When the function button is pressed, the mouse enters the line drawing mode, and the embedded software of the mouse waits to receive movement data. The user moves the mouse, and the mouse embedded software receives the movement data from the mouse sensor, wherein the mouse embedded software collects and stores the data of the previous N movements. The mouse embedded software determines the direction of the movement data collected in the first N times, and analyzes the movement direction. After the computer completes the direction determination, it performs straight line correction processing, and transmits the straight line correction processing results of the N times of movement data to the mouse embedded software, and the mouse embedded software stores the straight line correction processing results and presents the straight line trajectory on the display.

After that, when the user moves the mouse, the mouse embedded software receives the movement data, performs direction judgment processing, and retrieves the straight line correction processing result stored in the mouse embedded software, and directly presents the straight line trajectory on the display.
