Description

Method for triggering mouse rapid roller and linear mode by keyboard

Technical Field

The invention relates to the technical field of computer equipment, in particular to a method for triggering a mouse rapid roller and a linear mode by a keyboard.

Background

The keyboard and the mouse are standard computer peripheral devices, and usually, the keyboard and the mouse are used by a user in a matching way. Computer peripheral providers typically provide keyboards and mice, and provide corresponding computer software to provide more personalized services to users.

The scroll wheel is a standard component of a mouse and generally functions as an aid to vertical browsing, such as browsing a web page or document. The function of the scroll wheel is to scroll the screen up or down to enable page-turning browsing. When the user wants to continuously page, the scroll wheel needs to be continuously rolled. Continuous physical rolling, low efficiency, and fatigue. At present, most of the roller rapid page turning modes in the market adopt physical implementation modes, such as a MicroGear/MagSpeed physical roller scheme of Logitech and a physical roller scheme of Microsoft, but the adoption of the physical flying speed roller implementation scheme has high requirements on the fineness of mouse components and high manufacturing cost; in addition, the physical mode realizes the rapid page turning mode of the roller, and the rolling frequency is difficult to adjust.

In designing and editing an office scene, a user needs to use a mouse to draw a straight line. However, the mouse drawing function is generally free drawing by hand, and therefore, the mouse moving track is difficult to form a standard straight line. In general, when a user draws a graph, the user needs to draw a straight line by means of a software tool; when the software is not installed in the computer system, the user needs to download and install the software to draw the straight line, and the operation process is complicated. In addition, when software is used, a 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 subsequent engineering implementation.

And, generally, the computer keyboard standard is configured with a function key (Fn) for triggering a second function of the key, for example, implementing a multimedia Mute function by using a combination key "Fn + F1". The Fn key belongs to a self-defined key and does not have any function, and the Fn key is matched with other keys to trigger second functions of other keys.

Disclosure of Invention

In view of the above, the present invention is directed to a method for triggering a mouse fast wheel mode and a mouse straight-line mode by a keyboard, which combines device firmware and computer software, and allows a mouse fast wheel mode and a mouse straight-line mode to be triggered by function keys of the keyboard through the computer driving software, wherein one hand presses the function keys of the keyboard, the other hand uses the mouse, and the user experience and habit are better.

In order to achieve the purpose, the invention adopts the following technical scheme:

FIG. 2 is a detailed flow chart of the event processing of the present invention (including both the jog wheel and the straight line mode).

Detailed Description

Referring to fig. 1 and 2, a flow chart of event processing according to the present invention is shown.

A method for triggering mouse rapid roller and linear mode by keyboard includes providing function key on keyboard, receiving said event by PC software when said function key is pressed down, giving command to mouse and making mouse enter rapid roller and linear mode;

if: a user triggers a first rolling up or down event of a mouse roller, the event is reported normally, and then the rolling up or down event is automatically repeated at a set frequency, namely, the mouse enters a rapid mode repetition state;

if: the user starts to move the mouse, collects data of the previous N times of mouse movement, analyzes the data, judges the direction, enters a linear processing state once the judgment is finished, and sends the direction processing result of the N times of movement data to the PC; after that, the data obtained by the mouse moved by the user is corrected in the corresponding judgment direction, so that the data reported by the mouse is ensured to be linear data;

until the user releases the function key, the PC software receives the event and issues an instruction to inform the mouse, and the mouse leaves the rapid rolling wheel and linear mode and returns to the function of the standard mouse.

In this embodiment, the Fn function keys of the keyboard are used as the function keys, and any other keys of the keyboard may be used as the function keys. (other keys are also possible and the function is bound)

The mouse realizes the functions of a rapid roller and a linear mode. The mouse is connected with the computer system, and meanwhile, the mouse provides an instruction interface for the computer system. The computer system receives the instruction signal and sends an operation instruction to the mouse, so that the mouse enters a rapid rolling wheel mode and a linear mode. The computer system causes the mouse to leave the jog wheel or straight mode by receiving a reset signal and sending a return command to the mouse.

The computer system is provided with product tool software provided by the same mouse and keyboard manufacturer. The software is driving software and bears the intermediary action. The software enables the mouse and the keyboard to be linked, and provides a rapid roller and a linear mode for assisting office work.

After the mouse enters the fast wheel and linear mode, take the fast wheel mode as an example:

at the moment, the roller enters a default state of a rapid mode;

in the fast mode, when a user triggers a first scroll up or down event, the event is normally reported, and then the scroll up or down event is automatically repeated at a frequency of a set time interval (for example, 10ms, other time intervals can be defined), that is, the fast mode is in a repeated state; stopping automatically until the user triggers:

case 1: the user scrolls in the opposite direction for one lattice, automatically and repeatedly sends the information to stop, returns to the default state of the rapid mode, and continuously detects the subsequent user input.

Case 2: the user releases the function key, automatically and repeatedly sends and stops, leaves the rapid mode, and returns to the function of the standard roller.

Taking the straight line mode as an example:

in this case, step 1: the mouse enters a linear mode, is in a preparation state and waits for direction judgment;

step 2: when a user starts to move a mouse, collecting data of previous N times of mouse movement (wherein N is an integer from 16 to 20), analyzing the data, judging the direction, entering a linear processing state once the judgment is finished, and sending a direction processing result of the N times of movement data to a PC (personal computer); the direction judgment algorithm is as follows:

if (Diff < Factor), the value XY direction is identified, and further judgment of XY45 degrees or XY135 degrees is needed; wherein, if the polarity of Xsum and Ysum is opposite, namely one is positive number and the other is negative number, the XY 45-degree direction is obtained, otherwise, the polarity of Xsum and Ysum is the same, namely the two are integers or negative numbers at the same time, the XY 135-degree direction is obtained;

and step 3: then, the data obtained by the user moving the mouse are corrected according to the judgment direction, and the data reported by the mouse are ensured to be linear data;

and 4, 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 the linear direction is determined, the linear processing is performed on the movement data of the mouse in the X and Y directions, and according to the four directions, the corresponding processing algorithm is as follows:

if the determined straight line direction is the X-axis direction, discarding the moving data in the Y direction, and reporting the data moving in the X direction to the PC, wherein the reported data is [ X,0];

if the determined linear direction is the Y-axis direction, discarding the X-direction moving data, reporting the Y-direction moving data to the PC, and reporting the data to be [0, Y ];

The mouse is a two-dimensional pointing device whose reported data contains X and Y axis movement data from the sensors of the mouse, both X and Y being signed integers. The X-axis direction is the transverse direction, the Y-axis direction is the longitudinal direction, the XY 45-degree direction is the left-falling direction of Chinese character strokes, and the XY 135-degree direction is the right-falling direction of Chinese character strokes. The function keys are arranged on the mouse or the keyboard; or the function keys are keys independent from the mouse and the keyboard. And the data reported by the mouse is correspondingly controlled by the PC to present a linear track drawn by the mouse on the display.

When the straight lines in different directions need to be drawn, the straight line in one direction is drawn firstly, then the function key is released by a user, the function key is separated from the straight line mode and returns to the function of the standard mouse, the function key is pressed again, and the straight line drawing in the other direction is completed through the steps 1, 2, 3 and 4.

The design of the invention is characterized in that:

1. the mouse is combined with computer software through equipment firmware, the rapid rolling wheel mode and the linear mode of the mouse are triggered by the function keys of the keyboard through the computer driving software, the function keys of the keyboard are pressed by one hand, the mouse is used by the other hand, and the use habit and the use experience of a user are better.

3. The straight line mode can be triggered by a specific key, and the operation is simple; meanwhile, the method collects the multiple movement data of the user, analyzes and detects the direction, and finally corrects the data to ensure that the linear track of the mouse has no angular deviation; particularly, after the linear direction is judged, linear processing is carried out on the moving data of the mouse in the X and Y directions according to the four directions, and a user is ensured to obtain a perfect straight line from a data source head without the problem of angle deviation; and the mouse movement data come from a standard mouse sensor, the use habit of the user is reserved, and the humanized requirement is met.
