The current cursor control system is mainly a mouse and a digital tablet system (tablet). Users can choose according to their needs. For example, if a user needs to operate a drawing software, he can choose a digital tablet for drawing.

The known digital board system includes a digital board and a digital pen for controlling the operation mode of the cursor in the computer. There is a coil in the pen of the digital pen, and the working area of the digital board has antenna loops arranged equidistantly in an array of X and Y axes. These antenna circuits are used to receive the frequency signal emitted by the dedicated digital pen, and use the processing unit to analyze and process the received frequency signal to determine the coordinate position of the digital pen relative to the digital board, and then to drag (scrolling) , click (clicking) or track (tracing) function.

When the known digital board system is applied to the operation of drawing software, by changing the force of the nib of the digital pen touching the digital board, the coil will change the frequency of the frequency signal it emits, and then generate different thicknesses on the computer screen.

Detailed ways

Please refer to "FIG. 1", "FIG. 2" and "FIG. 3", which are respectively a three-dimensional structure schematic diagram, a circuit block diagram and a cursor control method according to "FIG. 2" of an embodiment of the cursor control system disclosed in the present invention. Schematic diagram of the process. The cursor control system 100 is used to control a cursor (not shown). The cursor control system 100 includes a cursor sensing device 102 and a cursor control device 104 . The cursor sensing device 102 can be but not limited to a wireless digital tablet (tablet), and the cursor control device 104 can be but not limited to a wireless digital pen. Wherein, the cursor control device 104 includes two coils 106 separated by a distance D between the two coils 106 . Receiving the first signal S ₁ and the second signal S ₂ respectively transmitted by the second coil 106, when the frequencies of the first signal S ₁ and the second signal S ₂ are different, the first signal S ₁ and the second signal S ₂ are simultaneously transmitted Receive (step 300). That is to say, the cursor sensing device 102 receives the first signal S ₁ and the second signal S ₂ respectively transmitted by the two coils 106. Since the frequencies of the first signal S ₁ and the second signal S ₂ are different, the first signal S ₁ and the second signal _S2 can be received by the cursor sensing device 102 at the same time, but this embodiment is not intended to limit the present invention.

A first coordinate _P1 and a second coordinate _P2 are sensed according to the first signal _S1 and the second signal _S2 (step 302). That is to say, the cursor sensing device 102 senses the first coordinate P ₁ and the second coordinate P ₂ after receiving the first signal S ₁ and the second signal S ₂ . Wherein, the first coordinate _P1 and the second coordinate _P2 are the absolute coordinates of the second coil 106 on the cursor sensing device 102 when the second coil 106 transmits the first signal _S1 and the second signal _S2 respectively. Since the two coils 106 are separated by a distance D, there is a distance A between the first coordinate P ₁ and the second coordinate P ₂ when there is an angle θ between the cursor sensing device 102 and the cursor control device 104 .

A corresponding control signal is output through the distance A between the first coordinate _P1 and the second coordinate _P2 (step 304 ). That is to say, the cursor sensing device 102 obtains an inclination value (not shown) according to the distance A, and then outputs a corresponding control signal (not shown). Since the cursor sensing device 102 outputs a corresponding control signal through the distance A, the angle θ between the cursor control device 104 and the cursor sensing device 102 can be from zero to ninety degrees. When the angle θ between the cursor control device 104 and the cursor sensing device 102 is larger, the distance A between the first coordinate P ₁ and the second coordinate P ₂ is smaller. When the angle θ between the cursor control device 104 and the cursor sensing device 102 is smaller, the distance A between the first coordinate P ₁ and the second coordinate P ₂ is larger. Wherein, when the included angle θ is 90 degrees, the first coordinate P ₁ and the second coordinate P ₂ coincide.

In this embodiment, the cursor sensing device 102 may include but not limited to a preset value E. When the inclination value is greater than the preset value E, the cursor sensing device 102 outputs a first control signal (not shown). When the inclination value is less than or equal to the predetermined value E, the cursor sensing device 102 outputs a second control signal (not shown). Wherein, the inclination value may be a numerical value indicating the angle θ between the cursor sensing device 102 and the cursor control device 104 . The default value E can be a numerical value indicating that the angle between the cursor sensing device 102 and the cursor control device 104 is 90 degrees, but in order to cooperate with the user's operating habits (because the user cannot continue to use the cursor sensing device 102 The angle θ between the cursor control device 104 and the cursor control device 104 is operated in a manner of 90 degrees), in this embodiment, the preset value E may represent that the angle θ between the cursor sensing device 102 and the cursor control device 104 is 4 Fifteen degrees, but this embodiment is not intended to limit the present invention, and can be adjusted according to the actual user's operating habits. Wherein, when the angle θ between the cursor sensing device 102 and the cursor control device 104 is smaller, the inclination value can be smaller; when the angle θ between the cursor sensing device 102 and the cursor control device 104 is larger, the inclination value can be This embodiment is not intended to limit the present invention.

For example, the first control signal can make the operation mode of the cursor unchanged. In more detail, when the cursor control system 100 is used to control the cursor in drawing software, the cursor is originally in the pencil mode, and when the cursor sensing device 102 outputs the first control signal, the cursor is also in the pencil mode to match the user's operating habits. The second control signal can change the operation mode of the cursor. In more detail, when the cursor control system 100 is used to control the cursor in drawing software, the cursor is originally in the pencil mode, and when the cursor sensing device 102 outputs the second control signal, the cursor changes to the watercolor pen mode, but in this embodiment It is not intended to limit the present invention, and the application of the first control signal and the second control signal can be adjusted according to actual needs.

In other words, the first control signal and the second control signal can also be used for other purposes. For example, when the cursor control device 104 does not move on the cursor sensing device 102, but only changes the angle θ between the cursor control device 104 and the cursor sensing device 102, the cursor will be displaced, and this phenomenon will cause the user to the inconvenience. The output of the first control signal and the second control signal can be fed back and the cursor is controlled not to move. Or the first control signal can make the cursor control system 100 draw a thin line when it is applied to the operation of the drawing software, and the second control signal can make the cursor control system 100 draw a thick line when it is applied to the operation of the drawing software, so as to solve the known problem The cursor control system requires force when drawing a thick line, which may easily cause damage to the cursor control device and the cursor sensing device.

Please refer to "Fig. 4", "Fig. 5" and "Fig. 6", which are respectively a three-dimensional structure diagram, a circuit block diagram and a cursor control according to "Fig. 5" of another embodiment of the cursor control system disclosed in the present invention. Schematic diagram of the method flow. The cursor control system 200 is used to control a cursor (not shown). The cursor control system 200 includes a cursor sensing device 202 and a cursor control device 204 . The cursor sensing device 202 can be but not limited to a wireless digital tablet (tablet), and the cursor control device 204 can be but not limited to a wireless digital pen. Wherein, the cursor control device 204 includes two coils 206 and a control unit 208 , and the two coils 206 are separated by a distance X. Receive the first signal S ₃ and the second signal S ₄ respectively transmitted by the second coil 206, when the frequency of the first signal S ₃ and the second signal S ₄ are the same, the first signal S ₃ and the second signal S ₄ are different The time is received (step 400). That is to say, the frequency of the first signal _S3 and the second signal _S4 are the same, and the transmission time of the first signal _S3 and the second signal _S4 to the cursor sensing device 202 is staggered through the control unit 208, so that the cursor senses The time of receiving the first signal _S3 and the second signal _S4 by the detection device 202 is staggered to avoid mutual interference, but this embodiment is not intended to limit the present invention.

A first coordinate _P3 and a second coordinate _P4 are sensed according to the first signal _S3 and the second signal _S4 (step 402). That is to say, the cursor sensing device 202 senses the first coordinate P ₃ and the second coordinate P ₄ after receiving the first signal S ₃ and the second signal S ₄ . Wherein, the first coordinate _P3 and the second coordinate _P4 are the absolute coordinates of the second coil 206 on the cursor sensing device 202 when the second coil 206 transmits the first signal _S3 and the second signal _S4 respectively. Since the two coils 206 are separated by a distance X, when there is an angle α between the cursor sensing device 202 and the cursor control device 204 , there is a distance Y between the first coordinate P ₃ and the second coordinate P ₄ .

A corresponding control signal is output through the distance Y between the first coordinate _P3 and the second coordinate _P4 (step 404 ). That is to say, the cursor sensing device 202 obtains an inclination value (not shown) according to the distance Y, and then outputs a corresponding control signal (not shown). Since the cursor sensing device 202 outputs a corresponding control signal through the distance Y, the angle α between the cursor control device 204 and the cursor sensing device 202 can be from zero to ninety degrees.

When the angle α between the cursor control device 204 and the cursor sensing device 202 is larger, the distance Y between the first coordinate P ₃ and the second coordinate P ₄ is smaller. When the angle α between the cursor control device 204 and the cursor sensing device 202 is smaller, the distance Y between the first coordinate P ₃ and the second coordinate P ₄ is larger. Wherein, when the included angle α is ninety degrees, the first coordinate P ₃ and the second coordinate P ₄ coincide.

In this embodiment, the cursor sensing device 202 may include but not limited to a preset value F, and when the inclination value is greater than the preset value F, the cursor sensing device 202 outputs a first control signal (not shown). When the inclination value is less than or equal to the predetermined value F, the cursor sensing device 202 outputs a second control signal (not shown). Wherein, the inclination value can be a numerical value indicating the angle α between the cursor sensing device 202 and the cursor control device 204, and the preset value F can be a value indicating that the angle α between the cursor sensing device 202 and the cursor control device 204 is The value of thirty degrees is not used in this embodiment to limit the present invention. When the angle α between the cursor sensing device 202 and the cursor control device 204 is smaller, the inclination value can be smaller, and when the angle α between the cursor sensing device 202 and the cursor control device 204 is larger, the inclination value can be larger , this embodiment is not intended to limit the present invention.

According to the cursor control device, system and method disclosed in the present invention, a relative control signal can be output according to the distance between the first coordinate and the second coordinate sensed by the cursor sensing device, thereby controlling the operation mode of the cursor. For example: when the cursor control system is in the drawing software, the change of the distance between the first coordinate and the second coordinate can cause the cursor to change the mode of the brush or the thickness of the line, or the cursor control system can compensate for only changing the included angle to produce cursor displacement The problem. Therefore, the cursor control device, system and method disclosed in the present invention can solve the problems existing in the conventional cursor control system (that is, the digital board system). Moreover, when the frequencies of the first signal and the second signal transmitted by the two coils are different, the first signal and the second signal can be received by the cursor sensing device at the same time. When the frequencies of the first signal and the second signal transmitted by the two coils are the same, the first signal and the second signal can be received by the cursor sensing device at different times through the control unit of the cursor control device, so as to avoid mutual interference. The cursor sensing device senses an error.
