Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Example 1
Fig. 1 is a flowchart of a method for controlling a mouse pointer according to an embodiment of the present invention, where the method can be performed by a device for controlling a mouse pointer. As shown in fig. 1, the method specifically includes the following steps:
Step 110, determining the relative orientation 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, a mouse pointer on a control screen can be controlled to move at intervals, and the control of the page turning pen on the mouse pointer 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 electrified and binding with a computer is completed. The user holds the page turning pen to enable the pen point of the page turning pen to face to the preset boundary point on the 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 vertexes of the screen. The page turning pen is respectively pointed at four vertexes of the screen, and when the page turning pen faces to the boundary point, the relative position between the page turning pen and the screen is determined and used 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 a target relative orientation. After binding of the page turning pen with a computer is completed, an output voltage signal of a gyroscope built in the page turning pen can be acquired by the singlechip, the space state of the page turning pen is calculated, and an initial point of a mouse pointer is output. An initial point may be set in advance, for example, a midpoint of the screen is set as the initial point. The direction of the page turning pen is an initial angle, the page turning pen is rotated from the initial point to the boundary point, and 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, namely the relative direction of the target.
In this embodiment, optionally, determining the target relative orientation of the page turning pen when the page turning pen faces to the boundary point of the preset moving range on the screen includes: responding to a range determining 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 target relative orientation of the page turning pen when the page turning pen faces the boundary point according to the target output voltage signal.
Specifically, the user holds the page-turning pen with his/her pen tip facing the screen. The pen point of the page turning pen faces to the boundary point of the preset moving range on the screen, wherein the preset moving range can be the range of the screen, and the boundary point can be the vertexes of four corners of the screen. After the pen point is aligned to one boundary point, a user sends a range determining instruction through the page turning pen, and when the range determining instruction is sent to all four boundary points, the movable range of the mouse pointer 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 determining instruction, acquiring an output voltage signal of the 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 position with the screen according to the output voltage signal, namely the target relative position when the page turning pen faces the boundary point is obtained, wherein the target relative position is a three-dimensional rotation angle when the page turning pen nib points to the boundary point, and for example, the angle between the page turning pen and the plane of the screen, 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 beneficial effect of this setting is that the target output signal when the page turning pen points to the boundary point is determined, thereby 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 formally using the page-turning pen, and whether the page-turning pen is pointed out of the movement range may be determined in real time. And recording the target output voltage signal and the target relative azimuth of the gyroscope, storing the target output voltage signal and the target relative azimuth as boundary information of a screen, and improving the determination accuracy of a moving range, thereby improving the control accuracy of a mouse pointer.
And 120, judging whether the page turning pen is positioned outside the moving range according to the target relative position and the current relative position of the page turning pen in the moving process.
The pen point of the page turning pen faces to the screen, rotates around X, Y and the Z axis, and controls the mouse pointer to correspondingly move on the screen. In the moving process of the page turning pen, the current relative position 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 moving range boundary or not can be determined, namely whether the page turning pen points to a position outside the moving range of the screen or not can be determined. For example, it may be determined whether the current relative orientation is consistent with the target relative orientation, and if so, the boundary point of the movement range toward which the page turning pen is oriented may be determined. According to the relative target orientation of the pen point to the boundary point, the relative orientation of the page turning pen when the page turning pen faces the boundary line of the moving range can be obtained, and if the current relative range is consistent with the relative orientation of the page turning pen when the page turning pen faces the boundary line of the moving range, the boundary line of the page turning pen facing the moving range can be judged.
In this embodiment, optionally, determining whether the page turning pen is located outside the moving range according to the target relative position 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 target relative position with the current relative position, 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 azimuth, but the current output voltage of the gyroscope, and the current relative azimuth can be calculated according to the current output voltage. The current relative orientation may be the rotation angle between the current and the X, Y and Z axes of the page turning pen, or may be represented by the projection of the vector in the direction pointed by the page turning pen on the XZ, YZ and XY planes. The relative orientation of the target may also be represented by the projection of the angle or vector of the page-turning pen to three axes on three planes. Comparing the relative position of the target with the current relative position, wherein the relative position of the target is a condition for determining whether the page turning pen points out of the moving range, and determining whether the current relative position meets the condition for pointing out of the moving range according to the comparison result, if so, determining that the pen point of the page turning pen points out of the moving range; if not, determining that the pointing direction of the page turning pen is still within the moving range. The beneficial effects of setting up like this lie in, can confirm the current relative position of page turning pen in real time, in time judge whether the directional of page turning pen has exceeded the movable range, be convenient for follow-up under the condition that exceeds the movable range, continue to control the mouse pointer, avoid page turning pen and mouse's disconnection, improve the control accuracy of mouse pointer.
In this embodiment, optionally, comparing the target relative position with the current relative position, and determining whether the direction of the page turning pen is located 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 azimuth and a target three-dimensional rotation angle of the page turning pen in the target relative azimuth; 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 or not; if yes, determining that the orientation of the page turning pen is located outside the moving range.
Specifically, the relative orientation may be the rotation angle of the page turning pen about the X-axis, Y-axis, and Z-axis as the three-dimensional rotation angle. The three-dimensional rotation angle of the pen point of the page turning pen can be continuously changed in the moving process. And determining the target three-dimensional rotation angle of the relative direction of the target, and determining the three-dimensional rotation angle range when the page turning pen points to any point on the boundary line according to the target three-dimensional rotation angle. For example, if the page-turning pen points to the upper boundary of the screen and the mouse pointer is controlled to move on the upper boundary, the three-dimensional rotation angle between the page-turning pen and any point on the upper boundary is located between the target three-dimensional rotation angles of two vertices of the upper boundary of the screen. That is, the relative orientation of the page-turning pen when pointing to the boundary line can be determined from the target relative orientations of 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 under the current relative position is consistent with the target three-dimensional rotation angle of the page turning pen under the target relative position, the boundary point that the page turning pen controls the mouse pointer to reach the moving range can be determined. If the current relative position is consistent with the relative position when the boundary line is pointed, namely the current three-dimensional rotation angle is consistent with the three-dimensional rotation angle when the boundary line is pointed, determining that the current relative position of the page turning pen meets the condition of the boundary line pointing, and determining that the page turning pen points to the boundary line. If the current three-dimensional rotation angle is larger than the target three-dimensional rotation angle or the current three-dimensional rotation exceeds the range of the three-dimensional rotation angle when pointing to any point on the boundary line, determining that the pointing direction of the page turning pen is out of the moving range. The beneficial effects of setting up like this lie in, can in time accurate judgement page turning pen has pointed out outside the movable range, be convenient for confirm the virtual travel route of mouse pointer outside the movable range, avoid page turning pen and mouse disconnection, improve the control accuracy of mouse pointer.
And 130, if so, controlling the mouse pointer to be positioned at the boundary of the moving range, and 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.
The mouse pointer cannot exceed the outside of the screen, and if the page turning pen faces 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 pointing direction of the page turning pen moves out of the moving range, and the actual moving route of the page turning pen can be calculated through sensors such as a gyroscope and an accelerometer arranged in the page turning pen. The page turning pen may incorporate a 6-axis sensor, which 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. Wherein the virtual moving route of the mouse pointer may coincide with the actual moving route of the page turning pen or with the route of the actual moving route projected on the screen plane, but the mouse pointer may not actually move. The virtual movement route is an assumed movement route obtained by the movement of the mouse pointer along with the movement of the page turning pen outside the movement range.
In this embodiment, optionally, according to an actual movement route of the page turning pen outside the movement range, determining a virtual movement route of the mouse pointer outside the movement 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 X, Y and the Z axis 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 rotating angle change rate and the acceleration value.
Specifically, the gyroscope built-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 translation pen moving process, and the accelerometer built-in the page turning pen can determine the acceleration value of the page turning pen in X, Y and the Z axis in the translation pen moving process. And (3) carrying out primary integration on the acceleration value to obtain a speed value of the page turning pen, and carrying out secondary integration to obtain a displacement value of the page turning pen. According to the change rate of the rotation angle and the displacement value, the rotation direction and the movement displacement of the page turning pen equipment are determined, the change of the page turning pen equipment in a space state can be obtained, and according to the connection between the page turning pen and the mouse pointer, the virtual movement route of the mouse pointer outside the movement range is determined. Fig. 2 is a schematic diagram of pointing directions of a page-turning pen in a three-dimensional space according to an 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 a pen point of the page turning pen, rxz is the projection of an inertia force vector R on an XZ plane, and Ryz is the projection of the inertia force vector R on a YZ plane. Axz is the angle formed by Rxz and Z axis, ayz is the angle formed by Ryz and Z axis.
The rate of change of the angle of rotation of the page turning pen 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 both acquired data of an ADC (Analog to Digital Converter, analog-to-digital converter), adcGyroXZ represents a rotation angle of the projection of the vector R in the XZ plane, adcGyroYZ represents a rotation angle of the projection of the vector R in the YZ plane, and AdcGyroXY represents a 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, and may be 3.3V, for example. Alpha is a preset parameter and can be 1023 or 1024.VzeroRate is a static voltage and refers to the output value of the gyroscope when it is not affected by any rotation. The 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 page turning pen in the X, Y and Z-axis 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 sampled voltage value of the ADC at acceleration 0, and Sensitivity' is the accelerometer Sensitivity, which can be obtained by interrogation. After the acceleration in 3 directions is obtained, the velocity value can be obtained by the primary integration, and the displacement value can be obtained by the secondary integration.
According to the rotation angles and displacement values of the page turning pen in three directions, the movement route of the mouse pointer can be controlled, and the virtual movement route of the mouse pointer can be obtained because the mouse pointer cannot actually move outside the movement range. Through the built-in 6-axis sensor, the rotation direction and the movement displacement of the page turning pen can be perceived, the change of the page turning pen in a space state can be perceived, the determination precision of a virtual movement route is improved, the page turning pen and a mouse are ensured to be always connected, the phenomenon that the page turning pen cannot accurately control a mouse pointer after returning to a 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, and 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.
In the moving process of the page turning pen, whether the pointing 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 yes, determining an 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 movement of the mouse pointer in the movement range according to the actual movement route of the page turning pen in 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 rotation angle of the page turning pen around X, Y and the Z axis, and the acceleration values of the page turning pen in X, Y and the Z axis directions can be determined by a 6-axis sensor built in the page turning pen. 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 displacement amounts of the page turning pen on three planes according to the acceleration values. According to the change and 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 beneficial effect of the arrangement is that the calculation method of the moving route of the mouse pointer is unchanged no matter whether the page turning pen exceeds the moving range or not, the connection between the page turning pen and the mouse pointer is always kept, and the mouse pointer can rapidly 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-turning pen moves outside the upper screen boundary toward the upper screen boundary, the virtual mouse pointer moves downward along the virtual movement route without moving from the actual upper screen boundary toward the lower boundary, improving the control accuracy of the mouse pointer.
According to the technical scheme, the range of the relative azimuth of the page turning pen in the preset moving range is determined by determining the target relative azimuth 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 azimuth and the target relative azimuth. If so, the position of the mouse pointer at the boundary is enabled to continuously calculate the virtual moving route of the mouse pointer outside the moving range, namely the mouse pointer is considered to move along with the page turning pen outside the moving range. When the page turning pen returns to the moving range, the mouse pointer can continue to move along with the page turning pen in the moving range. The problem that in the prior art, after the page turning pen exceeds the moving range, the connection between the mouse pointer and the page turning pen is disconnected is solved, real-time control of the mouse pointer is achieved, the situation that the mouse pointer cannot correspond to the pointing position of the page turning pen after the page turning pen returns to the moving range is avoided, and the control precision of the mouse pointer is improved.
Example two
Fig. 3 is a flowchart of a method for controlling a mouse pointer according to a second embodiment of the present invention, which is further optimized based on the above embodiment, and the method can be performed by a device for controlling a mouse pointer. As shown in fig. 3, the method specifically includes the following steps:
Step 310, determining the relative orientation of the target when the page turning pen faces to the boundary point of the preset moving range on the screen.
Step 320, judging whether the page turning pen is located outside the moving range according to the target relative orientation and the current relative orientation of the page turning pen in the moving process.
And 330, if the page turning pen is not located outside the moving range, 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.
