However, the above-mentioned input method using a digital pen to perform manipulation indicators is convenient, but this method only provides the required relative displacement and moving track of the cursor on the general window screen, and its application range is very limited. Moreover, the area on the digital board that can be written by the digital pen is very limited. When the user wants to draw a straight line when using the drawing software, the writing area of the digital board often limits the displacement distance of the digital pen, resulting in interruption of the drawn line. . Just like this, there are also inconveniences when drawing. the

Detailed ways

In the following preferred embodiments, the input device with double induction coils and the output method of the rotation motion of the present invention will be described in detail. However, the concept of the invention can also be used in other areas. The following examples are only used to illustrate the purpose and technical solutions of the present invention, and are not intended to limit the scope thereof. the

FIG. 1 is a schematic diagram of an input device on a track retrieval device according to a first embodiment of the present invention. Referring to FIG. 1 , the input device 10 can be designed as a pen-shaped structure, but it is not limited thereto. A primary coil 11 and a secondary coil 12 are respectively provided inside the input device 10 (it should be noted that the term "main" or "secondary" for the coils is only used as an illustration to separate the two groups of coils, and there is no other limitation). Along the pen tip O of the input device 10 as the axis R, the primary coil 11 and the secondary coil 12 are arranged on opposite sides of the axis R respectively. In addition, the input device 10 further has a radio frequency circuit 13 , and electrically connects the primary coil 11 and the secondary coil 12 to the radio frequency circuit 13 respectively. the

In this embodiment, the primary coil 11 can generate a primary induction signal, and the secondary coil 12 can generate a secondary induction signal. Wherein, a main frequency zone where the main induction signal is located does not overlap with a secondary frequency section where the auxiliary induction signal is located. For example, the main frequency range of the main sensing signal can be 120K-250K Hz, and the secondary frequency range of the secondary sensing signal can be 40K-80K Hz, but it is not limited thereto. the

In addition, the track retrieval device 20 can be a digital board (Digital Board), but not limited thereto. The track retrieval device 20 includes a working area 21 for the input device 10 to move on the working area 21 . The working area 21 is formed by interlacing signal lines in the X-axis direction and the Y-axis direction, and constitutes a main sensing circuit 22 and a secondary sensing circuit 23 . When the pen tip O of the input device 10 touches the working area 21 , the main induction signal generated by the main coil 11 can be transmitted to the main induction circuit 22 through the radio frequency circuit 13 . Similarly, the auxiliary induction signal generated by the auxiliary coil 12 can also be transmitted to the auxiliary induction circuit 23 through the radio frequency circuit 13. the

In short, when the user holds the input device 10 to perform a trajectory displacement action on the working area 21 of the trajectory retrieval device 20 , the radio frequency circuit 13 can synchronously send the main sensing signal and the secondary sensing signal of different frequencies to the trajectory retrieval device 20 . At the same time, the main and auxiliary sensing circuits 22 and 23 can respectively receive the main sensing signal and the secondary sensing signal, and convert the main sensing signal and the secondary sensing signal into a main position signal and a secondary position signal respectively (for example, by filtering mode), so as to determine the trajectory of the input device 10 on the trajectory retrieval device 20 . However, obtaining the moving trajectory (such as a straight line, an oblique line, or a curve, etc.) of the input device 10 by the trajectory retrieval device 20 is a common prior art, and details are not repeated here. the

Next, the present invention will be described with another embodiment. As shown in FIG. 2 , it is a schematic diagram of an input device on a track retrieval device according to a second embodiment of the present invention. Its specific implementation is roughly the same as the aforementioned embodiments, and only the differences will be described below. The input device 10 also includes a switch 14 (Swich) for electrically connecting the primary coil 11 and the secondary coil 12 respectively. The main coil 11 can generate a main induction signal, and the auxiliary coil 12 can generate an auxiliary induction signal, and make a main frequency range where the main induction signal is located overlap with a sub frequency area where the auxiliary induction signal is located. the

In this embodiment, the switcher 14 transmits the main induction signal or the auxiliary induction signal to the radio frequency circuit 13 in an alternating manner. In simple terms, when the switch 14 is transmitting the main sensing signal, its secondary sensing signal is temporarily stored in a buffer memory (Buffer) (not shown). Afterwards, after the switcher 14 finishes transmitting the main sensing signal, it then transmits the secondary sensing signal to the radio frequency circuit 13, and temporarily stores the main sensing signal into a memory (not shown). In this way, the switch 14 can respectively transmit the main sensing signal and the secondary sensing signal to the radio frequency circuit 13 in turn within a specific time interval. the

According to the specific time or receiving times set by the switcher 14, the radio frequency circuit 13 receives the main induction signal and the auxiliary induction signal in turn at different times, and then the main induction signal and the auxiliary induction signal are sent to the track in turn by the radio frequency circuit 13 The main and auxiliary sensing circuits 22 and 23 of the retrieval device 20 receive the signal to determine the position of the input device 10 on the track retrieval device 20 . the

In addition, the input device 10 of the present invention is not limited to a digital pen or other pen-shaped structures, and the input device 10 can also be designed as a mouse structure. As shown in FIG. 3 , it is a schematic diagram of the input device of the third embodiment on the track retrieval device. Its specific implementation is roughly the same as the aforementioned embodiments, and only the differences will be described below. The input device 10 can be a mouse structure (such as a wired mouse or a wireless mouse), and a primary coil 11 and a secondary coil 12 are arranged in parallel with each other inside the input device 10 . And the primary coil 11 and the secondary coil 12 are respectively electrically connected to the radio frequency circuit 13 . the

In this way, the user can hold the input device 10 and move on the working area 21 of the trajectory retrieval device 20 . At this time, the main induction signal generated by the main coil 11 can be transmitted to the main induction circuit 22 through the radio frequency circuit 13 . Similarly, the auxiliary induction signal generated by the auxiliary coil 12 can also be transmitted to the auxiliary induction circuit 23 through the radio frequency circuit 13 . In this way, when the user manipulates the input device 10 (such as a wireless mouse), the radio frequency circuit 13 can synchronously send the main sensing signal and the auxiliary sensing signal to the main and auxiliary sensing circuits 22 and 23, and then send the main sensing signal and the auxiliary sensing signal They are respectively converted into a main position signal and a secondary position signal (for example, by filtering), so as to determine the traveling track of the input device 10 on the track search device 20 . the

In addition, as shown in FIG. 4 , it is a schematic diagram of the input device of the fourth embodiment on the track retrieval device. Its specific implementation is roughly the same as the aforementioned embodiments, and only the differences will be described below. In this embodiment, the input device 10 (such as a mouse structure) further includes a switch 14 (Swich), which is electrically connected to the primary coil 11 and the secondary coil 12 respectively. And make the main frequency section of the main induction signal generated by the main coil 11 overlap with the sub frequency section of the auxiliary induction signal generated by the auxiliary coil 12 . the

Therefore, the switcher 14 can alternately transmit the main induction signal or the auxiliary induction signal to the radio frequency circuit 13 at different times, and then the main induction signal and the auxiliary induction signal are transmitted to the radio frequency circuit 13 in turn. The main and auxiliary sensing circuits 22 and 23 of the trajectory retrieval device 20 receive the signal to determine the travel trajectory of the input device 10 on the trajectory retrieval device 20 . the

As shown in FIG. 5 , it is a flowchart of a method for outputting a rotation signal from an input device with double induction coils. According to the structure of each embodiment of the above-mentioned input device, all can be applied to the method flow chart of FIG. For a time, receive the main induction signal and the auxiliary induction signal with the trajectory retrieval device 20, and convert the main induction signal and the auxiliary induction signal into a first main position signal and a first auxiliary position signal; step S230, at a second time Rotate the input device 10 to receive the main induction signal and the auxiliary induction signal again with the trajectory retrieval device 20, and convert the main induction signal and the auxiliary induction signal into a second main position signal and a second auxiliary position signal; step S240, compare The first main position signal and the second main position signal, and compare the first sub-position signal and the second sub-position signal, so that the trajectory retrieval device outputs a rotation signal to an electronic device, and the electronic device executes an action command correspondingly according to the rotation signal . the

In order to describe the signal output mode of the rotation direction more clearly, FIG. 6 and FIG. 7 are illustrated in detail, and can be applied to each embodiment shown in FIG. 1 to FIG. 4 , but not limited to the aforementioned embodiments. 6 and 7 are schematic diagrams for determining the rotation direction of the input device with double induction coils. The X and Y shown in the figure represent the X-axis direction and the Y-axis direction in the two-dimensional coordinates, and the pen tip O of the input device 10 is used as the intersection point of the X-axis and the Y-axis, and the X-axis and the Y-axis are divided into There are first quadrant (+, +), second quadrant (-, +), third quadrant (-, -) and fourth quadrant (+, -). The main induction signal and the auxiliary induction signal sent by the main coil 11 and the auxiliary coil 12 are converted into a first main position signal A and a first auxiliary position signal B respectively. Based on this, the positions of the first main position signal A (hereinafter referred to as point A) and the first auxiliary position signal B (hereinafter referred to as point B) between the quadrants are determined.

When the user rotates the input device 10, the pen tip O can be used as a reference point, or the midpoint between the main coil 11 and the secondary coil 12 can be used as a reference point, so that point A moves to point A' (that is, represents the second main position signal A'), point B moves to point B' (that is, represents the second secondary position signal B'). If point A moves to point A', and point B moves to point B' in the order of the first quadrant→fourth quadrant→third quadrant→second quadrant (as shown in Figure 6), then The trajectory retrieval device 20 determines that the input device 10 rotates in a clockwise direction, so as to output a clockwise rotation signal to the electronic device (not shown), and then controls the electronic device to switch to the first mode. the

If point A moves to point A', and point B moves to point B' in the order of the first quadrant→second quadrant→third quadrant→fourth quadrant (as shown in Figure 7), then The trajectory retrieval device 20 determines that the input device 10 rotates in a counterclockwise direction, so as to output a counterclockwise rotation signal to the electronic device (not shown), and then controls the electronic device to switch to the second mode. the

It can be understood that when the input device 10 rotates, the trajectory retrieval device 20 can also simply determine the coordinate changes of the X-axis and Y-axis when point A moves to point A', and determine the X-axis when point B moves to point B' , The coordinate change of the Y axis. Since the movement of point A on the X-axis and the Y-axis must be "same" and "opposite" to the movement of point B on the X-axis and Y-axis, the trajectory retrieval device 20 performs a sequence from the determinable input device 10. Clockwise or counterclockwise rotation. For example, when the coordinate system of point A on the Y axis changes from large to small, and the corresponding point B changes from small to large in the coordinate system of the Y axis, it means a clockwise rotation. the

In this way, by rotating the input device 10 on the trajectory retrieval device 20, the rotation direction of the input device 10 (such as clockwise or counterclockwise) is judged, and then a corresponding clockwise rotation signal or a corresponding counterclockwise rotation signal is output. The rotation signal in the clockwise direction is sent to the electronic device, so that the electronic device executes an action command correspondingly according to the signal of the rotation direction. For example, when the input device 10 is rotated clockwise, the window screen of the electronic device (such as a computer) can be controlled to rotate clockwise (ie execute the first mode). If the input device 10 is rotated counterclockwise, the window screen can be manipulated to rotate counterclockwise (ie, execute the second mode). the

However, this is an example description, not intended to limit the patent scope of the present invention. It can also rotate the input device 10 clockwise or counterclockwise to correspond to action commands for manipulating the electronic device, including but not limited to functions such as zooming in or zooming out the window. Alternatively, the object in the window can be rotated. For example, the object can be a 3D model drawn by an application program (such as drawing software), and the rotation direction of the input device 10 can be used to control the 3D model to rotate at an angle of 360°. It is only necessary to operate the electronic device with the clockwise rotation signal and the counterclockwise rotation signal to switch between the first mode and the second mode, or execute an action command corresponding to the rotation signal. the

Furthermore, another embodiment is used to clearly describe another way of outputting the signal of the rotation direction, especially illustrated in FIG. 9 and FIG. 10 , and the embodiment shown in FIG. 8 can be applied, but not limited thereto. 9 and 10 are schematic diagrams for determining the rotation direction of the input device with double induction coils. X and Y shown in the figure represent the X-axis direction and the Y-axis direction in the two-dimensional coordinates. In this embodiment, the first main position signal A generated by the main coil 11 of the input device 10 is used as a reference point, or the first main position signal A is located at the intersection of the X axis and the Y axis, while the X axis and the Y axis The axis is divided into the first quadrant (+, +), the second quadrant (-, +), the third quadrant (-,-) and the fourth quadrant (+,-), and the first quadrant produced by the secondary coil 12 The auxiliary position signal B is rotationally shifted relative to the first main position signal A. the

When the user rotates the input device 10, the first main position signal A of the main coil 11 can be used as a reference point, that is, point A is fixed, so that point B moves to point B' (that is, represents the second secondary position signal B') . If the order in which point B moves to point B' is from the first quadrant→the fourth quadrant→the third quadrant→the second quadrant (as shown in Figure 9), then the track retrieval device 20 determines that the input device 10 is moving along Rotate in a clockwise direction, so as to output a clockwise rotation signal to the electronic device (not shown), and then control the electronic device to switch modes or execute specific action commands. the

If the order in which point B moves to point B' is from the first quadrant → the second quadrant → the third quadrant → the fourth quadrant (as shown in Figure 10), then the trajectory retrieval device 20 determines that the input device 10 is moving along the Rotate in a counterclockwise direction, so as to output a counterclockwise rotation signal to the electronic device (not shown), and then control the electronic device to switch modes or execute specific action commands. the

It is particularly noteworthy that the user can also use the first secondary position signal B of the secondary coil 12 as a reference point, while the first primary position signal A of the primary coil 11 rotates relative to the first secondary position signal B; due to the way of judging are the same and therefore not discussed separately. the

Certainly, the present invention also can have other various embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these Corresponding changes and deformations should belong to the scope of protection of the appended claims of the present invention. the
