Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.
The method is suitable for the situation that the cursor moves along with the pen point of the mouse pen on the intelligent terminal. The intelligent terminal can comprise a screen-equipped and intelligent terminal such as a tablet computer, a smart phone and a palm computer.
Fig. 1 shows a method for moving a cursor of an intelligent terminal along with a pen point of a mouse pen according to an embodiment of the present invention. The method for moving the cursor of the intelligent terminal along with the pen point of the mouse pen runs on the intelligent terminal. The method for the intelligent terminal cursor to move along with the pen point of the mouse pen comprises the following steps:
s150: and receiving a moving signal sent by the mouse pen. The moving signal comprises the moving direction of the pen point when the pen point moves a preset distance relative to the front position of the pen point on a motion plane by taking the screen surface of the intelligent terminal as a motion plane.
The pen point of the mouse pen moves on a screen surface of the intelligent terminal as a motion plane, and through the positioning function of the mouse pen, a moving signal is sent to the intelligent terminal every time the pen point moves a preset distance relative to the front position of the pen point. The moving signal comprises the moving direction of the pen point of the mouse pen, so that the mobile terminal can determine the current position of the cursor according to the previous position, the preset distance and the moving direction of the cursor.
It should be noted that, when the driver of the mouse pen is installed, or after the driver is installed, the mouse pen needs to send a preset distance to the intelligent terminal. The writing recognition precision of the mouse pen can be achieved by the preset distance, the self positioning precision of the mouse pen is generally higher than that of the infrared touch frame, and therefore the writing recognition precision of the intelligent terminal cursor moving along with the pen point of the mouse pen through the self positioning function of the mouse pen is higher than that of the intelligent terminal cursor moving along with the pen point of the mouse pen through the positioning function of the infrared touch frame. The recognition accuracy of a mouse pen, for example, is 1/1000 inches, i.e., the predetermined distance is 0.0254 mm. Therefore, the mobile signal does not need to be carried with the preset distance every time the mobile signal is sent, and resources are saved.
S170: and determining the current position of the cursor according to the previous position of the cursor, the preset distance and the moving direction.
When the intelligent terminal receives a moving signal, the position of the cursor corresponding to the mouse pen when the mouse pen sends the moving signal, namely the current position of the cursor, can be determined according to the previous position of the cursor, the preset distance and the moving direction in the received moving signal.
When the mouse pen moves to the position of the next movement signal to be sent, the mouse pen sends the next movement signal. And when the intelligent terminal receives a new moving signal, taking the current position corresponding to the previous moving signal as the previous position of the cursor. Therefore, repeated execution is realized, and the cursor of the intelligent terminal moves along with the pen point of the mouse pen.
According to the method for the intelligent terminal cursor to move along with the pen point of the mouse pen, when the intelligent terminal cursor works, when a moving signal is obtained every time, the previous position of the cursor is set to be the current position corresponding to the previous moving signal, and the current position corresponding to the current moving signal is determined according to the previous position, the preset distance and the moving direction of the cursor again. The obtained moving signal is sent when the pen point moves a preset distance relative to the front position of the pen point by taking the screen surface of the intelligent terminal as a moving plane, and the recognition accuracy of the mouse pen is higher than that of the infrared touch frame, so that the writing recognition accuracy of the method for moving the cursor of the intelligent terminal along with the pen point of the mouse pen is high.
Referring to fig. 2, in one embodiment, before the step of receiving the movement signal sent by the mouse pen, that is, step S250, the method further includes:
s210: and receiving a verification signal sent by the mouse pen.
A key on the mouse pen can be used as a check key, and a check signal is sent to the intelligent terminal through the check key. It should be noted that the screen surface of the intelligent terminal is provided with a mouse check point, and the mouse check point can be customized, for example, the mouse check point can be the position of the lower left corner, the center point, the upper left corner and the like of the screen surface. When the pen point of the mouse pen moves to the mouse check point, the check key can be used for sending a check signal to the intelligent terminal. And the intelligent terminal receives the inspection signal sent by the mouse pen.
S230: and moving the cursor to a preset check point according to the check signal.
And when the intelligent terminal receives the inspection signal, the cursor is moved to a preset check point. The preset check point is a preset position to which a corresponding cursor should move when the mouse pen moves to the mouse check point on the surface of the screen. Therefore, the pen point position of the mouse pen and the cursor position of the intelligent terminal are verified.
Specifically, moving the cursor to the preset check point according to the check signal may be implemented by a set positioning function, such as a SetCursorPOS function, that moves the cursor to a designated position of the screen. More specifically, setting the positioning function includes two parameters: a new X-axis coordinate of the cursor and a new Y-axis coordinate of the cursor; setting two parameters for setting the positioning function as an X-axis coordinate and a Y-axis coordinate of the preset check point, namely setting a new X-axis coordinate of the cursor as the X-axis coordinate of the preset check point and setting the new Y-axis coordinate of the cursor as the Y-axis coordinate of the preset check point.
In one embodiment, the function prototype and parameters for setting the positioning function are described below.
Function prototype: BOOL SetCursorPOS (int X, int Y);
parameters are as follows:
x: a new X coordinate of the cursor is specified, expressed in screen coordinates.
Y: a new Y coordinate of the cursor is specified in screen coordinates.
In one embodiment, the step of determining the current position of the cursor according to the previous position of the cursor, the preset distance and the moving direction includes: determining the current position of the cursor according to the previous position of the cursor, the preset distance, the moving direction and a scale factor; the scale factor is the pointer speed at which the cursor moves.
If the distance of the pen point of the mouse pen moving is X and the scale factor is N, the distance of the cursor moving of the intelligent terminal is NX, and the moving direction of the cursor moving is consistent with the moving direction of the mouse pen.
Specifically, in order to move the mouse pen by a distance of X, the cursor under the display screen will also move by a distance of X, the value of the scale factor being 1.
More specifically, when the cursor is moved to a preset check point according to the check signal, the scale factor N may be synchronously set to 1, so that the mouse pen moves by the distance of X, and the cursor under the display screen also moves by the distance of X. Setting the scaling factor may be accomplished by a system level parameter setting function, such as the SystemParameterinfo function. The SystemParameterinfo function may query or set system level parameters or may update user profiles in the set parameters. For ease of understanding, the SystemParameterinfo function is described below.
In one embodiment, the system level parameter setting function may be:
B00L SystemParametersinfo(SPI_GETMOUSESPEED，0，pvParam，SPIF_SENDCHANGE)。
among them, SPI _ getmouseed is used for Windows NT 5.0 and later versions, Windows 98, to retrieve the current mouse speed. The speed of the mouse determines how far the mouse is moved, and how far the pointer of the mouse will move.
The parameter pvParam points to an integer variable that receives a value between 1 (slowest) and 20 (fastest), with a default value of 10. This value may be set by the end user using a mouse control panel application or using an application that calls SPI _ setup. It should be noted that, in this embodiment, pvParam needs to be set to 1 by SPI _ setsovelocity. The SPI _ SETMOUSESPEED is used for Windows NT 5.0 and later versions and Windows 98, and the current mouse speed is set.
SPIF _ SENDCHANGE for broadcasting WM _ SETTINGCHANGE messages after updating user profiles.
Referring to fig. 3, in an embodiment, the step of determining the current position of the cursor according to the previous position of the cursor, the preset distance, and the moving direction includes:
s371: acquiring the previous position of the cursor; the previous position is the current position corresponding to the last mobile signal;
s373: and determining the position which moves the preset distance according to the moving direction as the current position corresponding to the current moving signal on the basis of the previous position.
And acquiring the current position corresponding to the previous moving signal as the previous position of the cursor. And then, on the basis of the previous position, determining the position which moves the preset distance according to the moving direction as the current position corresponding to the current moving signal. When a next moving signal is received, the current moving signal is a previous moving signal relative to the next moving signal, and the current position is a previous position. Therefore, repeated execution is realized, and the cursor of the intelligent terminal moves along with the pen point of the mouse pen.
Referring to fig. 4, the present invention further provides an apparatus for moving an intelligent terminal cursor along with a pen point of a mouse pen according to an embodiment of the present invention, where the apparatus for moving an intelligent terminal cursor along with a pen point of a mouse pen corresponds to the method for moving an intelligent terminal cursor along with a pen point of a mouse pen.
