Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart illustrating a method for controlling a mouse pointer according to an embodiment of the present invention, where the method is applicable to a case where a page turning pen is used to control the mouse pointer, and the method can be executed by a control device of the mouse pointer. As shown in fig. 1, the method specifically includes the following steps:
and step 110, determining the relative position of the target when the page turning pen faces to the boundary point of the preset moving range on the screen.
The page turning pen is a digital page turning pen and can control a mouse pointer on a screen to move in an air-isolated mode, and the control of the mouse pointer by the page turning pen can be determined by the pen point state of the page turning pen. Before the page turning pen is used, the page turning pen is powered on and is bound with a computer. A user holds the page turning pen in a hand mode, and a pen point of the page turning pen faces to a preset boundary point on a screen. The range of the screen may be preset as a movement range in which the mouse pointer is movable, and the boundary points may be four vertices of the screen. And respectively pointing the page turning pen to four vertexes of the screen, and determining the relative position between the page turning pen and the screen when the page turning pen faces to the boundary point as the target relative position. The relative orientation may refer to an angle between the page turning pen and the boundary point, for example, a horizontal direction may be taken as an X axis, a direction perpendicular to the screen may be taken as a Y axis, and a vertical direction may be taken as a Z axis, so that a three-dimensional angle between the page turning pen and the screen when pointing to the boundary point may be obtained as the target relative orientation. After the page turning pen is bound with a computer, the single chip microcomputer can collect output voltage signals of a gyroscope arranged in the page turning pen, the space state of the page turning pen is calculated, and the initial point of a mouse pointer is output. An initial point may also be set in advance, for example, a midpoint of the screen as the initial point. And rotating the page turning pen from the initial pointing point to the boundary pointing point by taking the initial page turning pen facing the initial point as an initial angle, wherein the obtained three-dimensional rotation angle is the three-dimensional angle between the page turning pen and the screen when the page turning pen points to the boundary point, and is the target relative direction.
In this embodiment, optionally, determining the relative position of the target when the page turning pen faces the boundary point of the preset movement range on the screen includes: responding to a range determination instruction sent by a page turning pen towards a boundary point of a preset moving range on a screen, and determining a target output voltage signal when the page turning pen faces the boundary point; and determining the relative position of the target when the page turning pen faces the boundary point according to the target output voltage signal.
Specifically, the user holds the page turning pen to face the pen point to the screen. The pen point of the page turning pen is opposite to the boundary point of the preset movement range on the screen, the preset movement range can be the range of the screen, and the boundary point can be the top points of four corners of the screen. After the pen point is aligned with one boundary point, a user sends a range determining instruction through the page turning pen, and after the range determining instruction is sent to all four boundary points, the moving range of the mouse pointer which can move is determined, namely the page turning pen can only control the mouse pointer to move in a quadrangle formed by the four boundary points.
And after responding to the range determination instruction, acquiring an output voltage signal of a gyroscope in the page turning pen as a target output voltage signal. The target output voltage signal is a voltage signal output when the page turning pen faces the boundary point. The page turning pen can calculate the relative orientation between the page turning pen and the screen according to the output voltage signal, namely the target relative orientation when the page turning pen faces the boundary point is obtained, wherein the target relative orientation is the three-dimensional rotation angle when the pen point of the page turning pen points to the boundary point, and for example, the angle between the page turning pen and the screen plane, the angle between the page turning pen and the horizontal ground and the angle between the page turning pen and the vertical plane can be obtained. The method has the advantages that the target output signal when the page turning pen points to the boundary point is determined, so that the relative position of the target is determined, and the moving range of the mouse pointer is determined according to the relative position of the target. That is, the movement range of the mouse pointer on the screen may be determined before the flipper pen is used formally, and whether the flipper pen points out of the movement range may be determined in real time. And recording a target output voltage signal and a target relative direction of the gyroscope, storing the target output voltage signal and the target relative direction as boundary information of a screen, and improving the determination precision of the moving range and further improving the control precision of a mouse pointer.
And step 120, judging whether the page turning pen is positioned outside the moving range according to the relative direction of the target and the current relative direction of the page turning pen in the moving process.
The pen point of the page turning pen faces the screen and rotates around X, Y and the Z axis, and the mouse pointer is controlled to move correspondingly on the screen. In the moving process of the page turning pen, the current relative direction between the page turning pen and the screen can be obtained in real time. According to the current relative position and the target relative position, whether the page turning pen controls the mouse pointer to reach the boundary of the moving range can be determined, namely whether the page turning pen points to a position outside the screen moving range can be determined. For example, whether the current relative orientation is consistent with the target relative orientation may be determined, and if so, it may be determined that the page turning pen is facing the boundary point of the moving range. And if the current relative range is consistent with the relative direction of the page turning pen towards the boundary line of the moving range, the page turning pen can be judged to face the boundary line of the moving range.
In this embodiment, optionally, determining whether the page turning pen is located outside the moving range according to the relative position of the target and the current relative position of the page turning pen in the moving process includes: acquiring a current output voltage signal of the page turning pen in the moving process, and determining a current relative position according to the current output voltage signal; and comparing the relative orientation of the target with the current relative orientation, and determining whether the orientation of the page turning pen is out of the moving range according to the comparison result.
Specifically, the data that the page turning pen can directly output is not the current relative orientation, but the current output voltage of the gyroscope, and the current relative orientation can be calculated according to the current output voltage. The current relative orientation may be the current rotation angle between the page turning pen and the X axis, the Y axis and the Z axis, or may be represented by the projection of the vector in the direction pointed by the page turning pen on the XZ plane, the YZ plane and the XY plane. The relative orientation of the target may also be represented by the projection of the angle or vector of the flipper pen to the three axes onto the three planes. Comparing the target relative orientation with the current relative orientation, wherein the target relative orientation is a condition for determining whether the page turning pen points out of the moving range, and according to the comparison result, determining whether the current relative orientation meets the condition for pointing out of the moving range, if so, determining that the pen point of the page turning pen points out of the moving range; if not, the direction of the page turning pen is still determined to be within the moving range. The mouse pointer control method has the advantages that the current relative position of the page turning pen can be determined in real time, whether the direction of the page turning pen exceeds the moving range or not is judged in time, the mouse pointer can be controlled continuously under the condition that the direction of the page turning pen exceeds the moving range, disconnection between the page turning pen and the mouse is avoided, and control precision of the mouse pointer is improved.
In this embodiment, optionally, comparing the relative position of the target with the current relative position, and determining whether the orientation of the page turning pen is outside the moving range according to the comparison result, includes: determining a current three-dimensional rotation angle of the page turning pen in the current relative direction and a target three-dimensional rotation angle of the page turning pen in the target relative direction; comparing the current three-dimensional rotation angle with the target three-dimensional rotation angle, and judging whether the current three-dimensional rotation angle is larger than the target three-dimensional rotation angle; if yes, determining that the orientation of the page turning pen is out of the moving range.
Specifically, the relative orientation may be a rotation angle of the page turning pen around the X-axis, the Y-axis, and the Z-axis as a three-dimensional rotation angle. The three-dimensional rotation angle of the pen point of the page turning pen can be changed continuously in the moving process. And determining a three-dimensional rotation angle of the target relative to the direction, and determining the three-dimensional rotation angle range when the page turning pen points to any point on the boundary line according to the three-dimensional rotation angle of the target. For example, the page turning pen points to the upper boundary of the screen, and the mouse pointer is controlled to move on the upper boundary line, so that the three-dimensional rotation angle between the page turning pen and any point on the upper boundary line is located between the target three-dimensional rotation angles of two vertexes of the upper boundary of the screen. That is, the relative position of the page turning pen when pointing to the boundary line can be determined according to the relative positions of the target at the four points. In the moving process of the page turning pen, if the current relative position calculated by the page turning pen is consistent with the target relative position, namely the current three-dimensional rotation angle of the page turning pen in the current relative position is consistent with the target three-dimensional rotation angle of the page turning pen in the target relative position, the situation that the page turning pen controls the mouse pointer to reach the boundary point of the moving range can be determined. And if the current relative position is consistent with the relative position when the current relative position points to the boundary line, namely the current three-dimensional rotation angle is consistent with the three-dimensional rotation angle when the current three-dimensional rotation angle points to the boundary line, determining that the current relative position of the page turning pen meets the condition of pointing to the boundary line, and determining that the page turning pen points to the boundary line. And if the current three-dimensional rotation angle is larger than the target three-dimensional rotation angle or the range of the three-dimensional rotation angle when the current three-dimensional rotation exceeds any point on the pointing boundary line, determining that the pointing direction of the page turning pen is positioned outside the moving range. The mouse pointer positioning method has the advantages that whether the page turning pen points out of the moving range can be timely and accurately judged, the virtual moving route of the mouse pointer out of the moving range can be conveniently determined, the page turning pen is prevented from being disconnected with the mouse, and the control precision of the mouse pointer is improved.
And step 130, if so, controlling the mouse pointer to be positioned at the boundary of the moving range, and determining the virtual moving route of the mouse pointer outside the moving range according to the actual moving route of the page turning pen outside the moving range.
And if the page turning pen is determined to face the moving range, namely the outside of the screen, the mouse pointer is controlled to be positioned at the boundary of the moving range. The direction of the page turning pen moves outside the moving range, and the actual moving route of the page turning pen can be calculated through sensors such as a gyroscope, an accelerometer and the like arranged in the page turning pen. The page turning pen may have a 6-axis sensor built in, and the 6-axis sensor may include a 3-axis gyroscope and a 3-axis accelerometer. According to the actual moving route of the page turning pen, the virtual moving route of the mouse pointer can be determined. The virtual moving route of the mouse pointer can be consistent with the actual moving route of the page turning pen, or the virtual moving route of the mouse pointer can be consistent with the route projected by the actual moving route on the screen plane, but the mouse pointer does not actually move. The virtual movement route is an assumed movement route of the mouse pointer along with the movement of the page flipper outside the movement range.
In this embodiment, optionally, determining a virtual moving route of the mouse pointer outside the moving range according to the actual moving route of the page turning pen outside the moving range includes: determining the rotation angle change rate of the page turning pen around X, Y and the Z axis and the acceleration value of the page turning pen in the X, Y and Z axis directions according to the actual moving route of the page turning pen outside the moving range; and determining a virtual moving route of the mouse pointer outside the moving range according to the rotation angle change rate and the acceleration value.
Specifically, the gyroscope arranged in the translation pen can determine the rotation angle change rate of the page turning pen around X, Y and the Z axis in the moving process of the translation pen, and the accelerometer arranged in the page turning pen can determine the acceleration values of the page turning pen in the X, Y and Z axis directions in the moving process of the translation pen. The speed value of the page turning pen can be obtained by integrating the acceleration value for the first time, and the displacement value of the page turning pen can be obtained by integrating the acceleration value for the second time. And determining the rotation direction and the movement displacement of the page turning pen device according to the rotation angle change rate and the displacement value, so as to obtain the change of the page turning pen device in the space state, and determining the virtual movement route of the mouse pointer outside the movement range according to the connection between the page turning pen and the mouse pointer. FIG. 2 is a schematic diagram of the direction of the page turning pen in a three-dimensional space according to the embodiment of the present invention. In fig. 2, the horizontal direction is taken as the X axis, the direction perpendicular to the screen is taken as the Y axis, and the vertical direction is taken as the Z axis. R is a vector pointed by the pen point of the page turning pen, Rxz is a projection of an inertia force vector R on an XZ plane, and Ryz is a projection of the inertia force vector R on a YZ plane. Axz is the angle formed by Rxz and Z axis, and Ayz is the angle formed by Ryz and Z axis.
The rate of change of the angle of rotation of the flipper about X, Y and the Z axis can be determined according to the following formula:
wherein, RateAxz is the rotation angle change rate of the gyroscope in the page turning pen around the Y axis, RateAyz is the rotation angle change rate of the gyroscope around the X axis, and RateAxy is the rotation angle change rate of the gyroscope around the Z axis. AdcGyroXZ, AdcGyroYZ and AdcGyroXY are all the collected data of an ADC (Analog to Digital Converter), and AdcGyroXZ represents the rotation angle of the projection of the vector R in the XZ plane, AdcGyroYZ represents the rotation angle of the projection of the vector R in the YZ plane, and AdcGyroXY represents the rotation angle of the projection of the vector R in the XY plane. Vref is the reference voltage of the ADC, and the value is determined by the model of the ADC, which may be 3.3V, for example. α is a preset parameter and may be 1023 or 1024. VzeroRate is a static voltage and refers to the output value of the gyroscope without any rotational influence. Sensitivity is the Sensitivity of the gyroscope. After the gyroscope has an initial position, the rotation change rate around X, Y and the Z axis is determined, and the rotation change rate is integrated to form a three-dimensional rotation angle, so that the gyroscope can sense the angle change of the page turning pen device in three directions in space.
The acceleration values of the flipper pen in the X, Y and Z directions can be determined according to the following formula:
wherein Rx is the acceleration value of the page turning pen in the X-axis direction, Ry is the acceleration value in the Y-axis direction, and Rz is the acceleration value in the Z-axis direction. AdcRx is the sample value of the ADC on the X-axis, AdcRy is the sample value of the ADC on the Y-axis, and AdcRz is the sample value of the ADC on the Z-axis. VzeroG is the sampling voltage value of the ADC when the acceleration is 0, and Sensitivity' is the Sensitivity of the accelerometer, and can be obtained through query. After the accelerations in 3 directions are obtained, the velocity value can be obtained through the first integration, and the displacement value can be obtained through the second integration.
According to the rotation angles and the displacement values of the page turning pen in three directions, the moving route of the mouse pointer can be controlled, and the virtual moving route of the mouse pointer can be obtained because the mouse pointer cannot actually move outside the moving range. Through the built-in 6 sensors, the rotation direction and the movement displacement of the page turning pen can be sensed, the change of the page turning pen in a space state can be sensed, the determination precision of a virtual movement route is improved, the page turning pen is guaranteed to be always connected with a mouse, the situation that the mouse pointer cannot be accurately controlled after the page turning pen returns to the movement range is avoided, and the control precision of the mouse pointer is improved.
And 140, judging whether the virtual moving route returns to the moving range, if so, controlling the mouse pointer to move in the moving range according to the actual moving route of the page turning pen in the moving range.
During the moving process of the page turning pen, whether the direction of the page turning pen returns to the moving range or not is judged in real time, namely whether the virtual moving route of the mouse pointer returns to the moving range or not is judged. If so, determining the actual moving route of the page turning pen in the moving range, and controlling the mouse pointer to move in the moving range according to the actual moving route.
In this embodiment, optionally, controlling the mouse pointer to move within the movement range according to the actual movement route of the page turning pen within the movement range includes: determining the current moving route of the mouse pointer in the moving range according to the actual moving route of the page turning pen in the moving range; and controlling the mouse pointer to move in the moving range according to the current moving route.
Specifically, whether the page turning pen points out of the moving range or in the moving range, the moving route of the mouse pointer is determined according to the actual moving route of the page turning pen. The rate of change of the angle of rotation of the flipper about X, Y and the Z axis, and the acceleration of the flipper in the X, Y and Z directions can be determined by a 6-axis sensor built into the flipper. And determining the rotation angle change of the page turning pen in three directions in space according to the rotation angle change rate. And determining the displacement of the page turning pen on three planes according to the acceleration value. According to the change and the displacement of the rotation angle, the current moving route of the mouse pointer on the screen can be determined, and the mouse pointer is controlled to move according to the current moving route. The mouse pointer calculation method has the advantages that no matter whether the page turning pen exceeds the moving range or not, the calculation method of the moving route of the mouse pointer is unchanged, the page turning pen is always kept in contact with the mouse pointer, and the mouse pointer can quickly correspond to the pointing position of the page turning pen after the page turning pen returns to the moving range. For example, when the page flipping pen moves to the upper boundary of the screen outside the upper boundary of the screen, the virtual mouse pointer moves downward along the virtual movement route without moving from the actual upper boundary of the screen to the lower boundary, improving the control accuracy of the mouse pointer.
According to the technical scheme of the embodiment, the range of the relative position of the page turning pen in the preset moving range is determined by determining the relative position of the target when the page turning pen faces the boundary point, and whether the page turning pen exceeds the preset moving range can be judged according to the current relative position and the relative position of the target. If so, enabling the mouse pointer to be located at the position of the boundary, and continuously calculating the virtual moving route of the mouse pointer outside the moving range, namely considering that the mouse pointer moves along with the page turning pen outside the moving range. After the page turning pen returns to the moving range, the mouse pointer can continuously move in the moving range along with the page turning pen. The problem of in the prior art, after the page turning pen surpassed the moving range, the mouse pointer was disconnected with the page turning pen's problem is solved, realize the real-time control to the mouse pointer, avoid the page turning pen after returning to the moving range, the condition that the mouse pointer can't correspond to the directional position of page turning pen takes place, improves the control accuracy of mouse pointer.
