本發明係為一種指標控制裝置、系統及其方法，特別係關於一種利用指標控制裝置與指標感測裝置的夾角大小控制指標的指標控制裝置、系統及其方法。The invention relates to an index control device, a system and a method thereof, in particular to an index control device, a system and a method thereof, which use an angle control index of an index control device and an index sensing device.
隨著資訊科技的發展，越來越多相關的電子產品被開發，以符合市場的需求，也使得電腦更容易讓使用者操作。現今的指標控制系統主要為滑鼠與數位板系統(Tablet)，使用者可以依據其需求而進行選擇，例如：使用者需進行繪圖軟體的操作，可選擇數位板以便進行製圖。With the development of information technology, more and more related electronic products have been developed to meet the needs of the market, making the computer easier for users to operate.

以上關於本發明的內容說明及以下之實施方式的說明係用以示範與解釋本發明的精神與原理，並且提供本發明的專利申請範圍更進一步的解釋。The description of the present invention and the following description of the embodiments of the present invention are intended to illustrate and explain the spirit and principles of the invention, and to provide further explanation of the scope of the invention.
請參照「第1圖」、「第2圖」與「第3圖」，係分別為依據本發明所揭露之指標控制系統的一實施例立體結構示意圖、電路方塊示意圖與依據「第2圖」的指標控制方法流程示意圖。指標控制系統100用以控制指標(未標示)，指標控制系統100包括指標感測裝置102與指標控制裝置104。指標感測裝置102可為但不限於無線數位板(Tablet)，指標控制裝置104可為但不限於無線數位筆。其中，指標控制裝置104包括二線圈106，二線圈106相隔一距離D。接收二線圈106所分別傳輸的第一信號S1 與第二信號S2 ，當第一信號S1 與第二信號S2 的頻率不同時，第一信號S1 與第二信號S2 係同時被接收(步驟-300)。也就是說，指標感測裝置102接收二線圈106所分別傳輸的第一信號S1 與第二信號S2 ，由於第一信號S1 與第二信號S2 的頻率不同，使得第一信號S1 與第二信號S2 可同時被指標感測裝置102接收，但本實施例並非用以限定本發明。Please refer to FIG. 1 , FIG. 2 and FIG. 3 , which are schematic diagrams of a three-dimensional structure, a circuit block diagram and a "block 2" diagram of an embodiment of an index control system according to the present invention. Schematic diagram of the indicator control method flow. The indicator control system 100 is used to control indicators (not shown), and the indicator control system 100 includes an indicator sensing device 102 and an indicator control device 104. The indicator sensing device 102 can be, but is not limited to, a wireless tablet, and the indicator control device 104 can be, but is not limited to, a wireless digital pen. The index control device 104 includes two coils 106 separated by a distance D. Receiving the first signal S 1 and the second signal S 2 respectively transmitted by the two coils 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 Received (step -300). That is, the index sensing device 102 receives the first signal S 1 and the second signal S 2 respectively transmitted by the two coils 106, and the first signal S is different because the frequencies of the first signal S 1 and the second signal S 2 are different. 1 and the second signal S 2 may be simultaneously received by the index sensing device 102, but this embodiment is not intended to limit the present invention.
依據第一信號S1 與第二信號S2 感應第一座標P1 與第二座標P2 (步驟-302)。也就是說，指標感測裝置102接收第一信號S1 與第二信號S2 後，感應出第一座標P1 與第二座標P2 。其中，第一座標P1 與第二座標P2 係為二線圈106分別發射第一信號S1 與第二信號S2 時，二線圈106分別於指標感測裝置102的絕對座標。由於二線圈106相隔一距離D，所以當指標感測裝置102與指標控制裝置104間具有夾角θ時，第一座標P1 與第二座標P2 間存在有一距離A。According to the first signal S 1 and second signal S 2 induction first coordinate and the second coordinate P 1 P 2 (step -302). That is, after receiving the first signal S 1 and the second signal S 2 , the index sensing device 102 senses the first coordinate P 1 and the second coordinate P 2 . The first coordinate P 1 and the second coordinate P 2 are when the two coils 106 respectively emit the first signal S 1 and the second signal S 2 , and the two coils 106 are respectively located at the absolute coordinates of the index sensing device 102 . Since the two coils 106 are separated by a distance D, when the index sensing device 102 and the index control device 104 have an angle θ, there is a distance A between the first coordinate P 1 and the second coordinate P 2 .
藉由第一座標P1 與第二座標P2 的距離A輸出對應的控制信號(步驟-304)。也就是說，指標感測裝置102依據距離A獲得傾角值(未標示)，進而輸出對應的控制信號(未標示)。由於指標感測裝置102藉由距離A而輸出對應的控制信號，所以指標控制裝置104與指標感測裝置102間的夾角θ係可為零到九十度的角度。當指標控制裝置104與指標感測裝置102間的夾角θ越大時，第一座標P1 與第二座標P2 的距離A越小。當指標控制裝置104與指標感測裝置102間的夾角θ越小時，第一座標P1 與第二座標P2 的距離A越大。其中，當夾角θ為九十度時，第一座標P1 與第二座標P2 重合。A corresponding control signal is output by the distance A between the first coordinate P 1 and the second coordinate P 2 (step-304). That is to say, the index sensing device 102 obtains a tilt value (not labeled) according to the distance A, and further outputs a corresponding control signal (not labeled). Since the index sensing device 102 outputs a corresponding control signal by the distance A, the angle θ between the index control device 104 and the index sensing device 102 can be an angle of zero to ninety degrees. When the angle θ between the index control device 104 and the index 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 index control device 104 and the index 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 angle θ is ninety degrees, the first coordinate P 1 and the second coordinate P 2 coincide.
在本實施例中，指標感測裝置102可包括但不限於一預定值E，當傾角值大於預定值E時，指標感測裝置102輸出第一控制信號(未標示)。當傾角值小於或等於預定值E時，指標感測裝置102輸出第二控制信號(未標示)。其中，傾角值可為表示出指標感測裝置102與指標控制裝置104之間夾角θ的數值。預定值E可為表示出指標感測裝置102與指標控制裝置104之間夾角成九 十度的數值，但為配合使用者的操作習慣(因使用者不可能持續以指標感測裝置102與指標控制裝置104間夾角θ成九十度的方式進行操作)，在本實施例中，預定值E可為表示出指標感測裝置102與指標控制裝置104之間夾角θ成四十五度的數值，但本實施例並非用以限定本發明，可依據實際使用者的操作習慣進行調整。其中，當指標感測裝置102與指標控制裝置104之間夾角θ越小時，傾角值可越小，當指標感測裝置102與指標控制裝置104之間夾角θ越大時，傾角值可越大，本實施例並非用以限定本發明。In the present embodiment, the index sensing device 102 can include, but is not limited to, a predetermined value E. When the tilt value is greater than the predetermined value E, the index sensing device 102 outputs a first control signal (not labeled). When the tilt value is less than or equal to the predetermined value E, the index sensing device 102 outputs a second control signal (not labeled). The tilt value may be a value indicating an angle θ between the index sensing device 102 and the index control device 104. The predetermined value E may be such that the angle between the index sensing device 102 and the index control device 104 is nine. The value of ten degrees, but in order to cooperate with the user's operating habits (because the user cannot continue to operate in such a manner that the angle θ between the index sensing device 102 and the index control device 104 is ninety degrees), in this embodiment, The predetermined value E may be a value indicating that the angle θ between the index sensing device 102 and the index control device 104 is forty-five degrees. However, this embodiment is not intended to limit the present invention, and may be adjusted according to actual user operating habits. . Wherein, when the angle θ between the index sensing device 102 and the index control device 104 is smaller, the inclination value can be smaller. When the angle θ between the index sensing device 102 and the index control device 104 is larger, the inclination value can be larger. This embodiment is not intended to limit the invention.
舉例而言，第一控制信號可使指標的運作模式不變。更詳細地說，當指標控制系統100係應用於控制繪圖軟體中的指標時，指標原本為鉛筆模式，當指標感測裝置102輸出第一控制信號時，指標亦為鉛筆模式，以配合使用者的操作習慣。第二控制信號可使指標的運作模式改變。更詳細地說，當指標控制系統100係應用於控制繪圖軟體中的指標時，指標原本為鉛筆模式，當指標感測裝置102輸出第二控制信號時，指標改變為水彩筆模式，但本實施例並非用以限定本發明，第一控制信號與第二控制信號的應用可依據實際需求而進行調整。For example, the first control signal can make the operation mode of the indicator unchanged. In more detail, when the indicator control system 100 is applied to the indicator in the control drawing software, the indicator is originally in the pencil mode. When the indicator sensing device 102 outputs the first control signal, the indicator is also in the pencil mode to match the user. Operating habits. The second control signal can change the mode of operation of the indicator. In more detail, when the index control system 100 is applied to control the index in the drawing software, the index is originally a pencil mode, and when the index sensing device 102 outputs the second control signal, the indicator is changed to the watercolor brush mode, but the implementation The example is not intended to limit the present invention, and the application of the first control signal and the second control signal may be adjusted according to actual needs.
換句話說，第一控制信號與第二控制信號亦可作為其他用途。舉例而言，當指標控制裝置104於指標感測裝置102上不移動，僅改變指標控制裝置104於指標感測裝置102間的夾角θ時，會使指標產生位移，此現象會造成使用者的不便。而第一控制信號與第二控制信號的輸出可回饋且控制指標不產生位移。更或者 第一控制信號可使指標控制系統100應用於繪圖軟體的操作時繪製出細線，而第二控制信號可使指標控制系統100應用於繪圖軟體的操作時繪製出粗線，藉以解決習知指標控制系統於繪製粗線時需用力且易造成指標控制裝置與指標感測裝置損壞的問題。In other words, the first control signal and the second control signal can also be used for other purposes. For example, when the index control device 104 does not move on the index sensing device 102, and only changes the angle θ between the index control device 104 and the index sensing device 102, the index is displaced, which may cause the user to inconvenient. The output of the first control signal and the second control signal can be fed back and the control index does not generate a displacement. More or The first control signal can cause the indicator control system 100 to draw a thin line when the drawing software is applied, and the second control signal can cause the indicator control system 100 to draw a thick line when the drawing software is used for the operation of the drawing software, thereby solving the conventional index control. The system needs to be forceful when drawing thick lines and easily cause damage to the indicator control device and the indicator sensing device.

Schematic diagram of the indicator control method flow. The indicator control system 200 is used to control indicators (not shown), and the indicator control system 200 includes an indicator sensing device 202 and an indicator control device 204. The indicator sensing device 202 can be, but is not limited to, a wireless tablet, and the indicator control device 204 can be, but is not limited to, a wireless digital pen. The index control device 204 includes two coils 206 and a control unit 208, and the two coils 206 are separated by a distance X. Receiving a second coil 206, respectively, a first signal S 3 and the second transmission signal S 4, S 3 when the first signal and the second signal frequency is the same S. 4, the first and the second signal S 3. 4 based on the signal S It is received at different times (step -400). That is, the first signal S 3 and the second signal S 4 have the same frequency, and the control unit 208 interleaves the time when the first signal S 3 and the second signal S 4 are transmitted to the index sensing device 202, thereby making the indicator The sensing device 202 receives the time of the first signal S 3 and the second signal S 4 to be staggered to avoid mutual interference, but the embodiment is not intended to limit the present invention.
依據第一信號S3 與第二信號S4 感應第一座標P3 與第二座標P4 (步驟-402)。也就是說，指標感測裝置202接收第一信號S3 與第二信號S4 後，感應出第一座標P3 與第二座標P4 。其中，第一座標P3 與第二座標P4 係為二線圈206分別發射第一信號S3 與第二信號S4 時，二線圈206分別於指標感測裝置202的絕對座標。由 於二線圈206相隔一距離X，所以當指標感測裝置202與指標控制裝置204間具有夾角α時，第一座標P3 與第二座標P4 間存在有一距離Y。According to the first signal and the second signal S 3 S 4 P 3 induction first coordinate and the second coordinate P 4 (step -402). That is to say, after receiving the first signal S 3 and the second signal S 4 , the index sensing device 202 senses the first coordinate P 3 and the second coordinate P 4 . The first coordinate P 3 and the second coordinate P 4 are when the two coils 206 respectively emit the first signal S 3 and the second signal S 4 , and the two coils 206 are respectively located at the absolute coordinates of the index sensing device 202 . Since the two coils 206 are separated by a distance X, when the index sensing device 202 and the index control device 204 have an angle α, there is a distance Y between the first coordinate P 3 and the second coordinate P 4 .
藉由第一座標P3 與第二座標P4 的距離Y輸出對應的控制信號(步驟-404)。也就是說，指標感測裝置202依據距離Y獲得傾角值(未標示)，進而輸出對應的控制信號(未標示)。由於指標感測裝置202藉由距離Y而輸出對應的控制信號，所以指標控制裝置204與指標感測裝置202間的夾角α係可為零到九十度的角度。A corresponding control signal is output by the distance Y between the first coordinate P 3 and the second coordinate P 4 (step-404). That is, the index sensing device 202 obtains a tilt value (not labeled) according to the distance Y, and then outputs a corresponding control signal (not labeled). Since the index sensing device 202 outputs a corresponding control signal by the distance Y, the angle α between the index control device 204 and the index sensing device 202 can be an angle of zero to ninety degrees.
當指標控制裝置204與指標感測裝置202間的夾角α越大時，第一座標P3 與第二座標P4 的距離Y越小。當指標控制裝置204與指標感測裝置202間的夾角α越小時，第一座標P3 與第二座標P4 的距離Y越大。其中，當夾角α為九十度時，第一座標P3 與第二座標P4 重合。When the angle α between the index control device 204 and the index 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 index control device 204 and the index 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 angle α is ninety degrees, the first coordinate P 3 and the second coordinate P 4 coincide.

When the angle α between the index sensing device 202 and the index control device 204 is smaller, the inclination value can be smaller. When the angle α between the index sensing device 202 and the index control device 204 is larger, the inclination value can be larger. The examples are not intended to limit the invention.
依據本發明所揭露之指標控制裝置、系統及其方法，可藉由指標感測裝置所感應的第一座標與第二座標間之距離大小而輸出相對的控制信號，進而控制指標的運作模式。例如：指標控制系統於繪圖軟體中時，第一座標與第二座標間的距離改變可使指標改變筆刷的模式或線條的粗細，更或者指標控制系統可補償僅改變夾角而產生指標位移的問題。因此，本發明所揭露之指標控制裝置、系統及其方法可解決習知指標控制系統(即數位板系統)所存在的問題。而且，當二線圈所發射第一信號與第二信號的頻率不同時，第一信號與第二信號可同時被指標感測裝置接收。當二線圈所發射第一信號與第二信號的頻率相同時，可藉由指標控制裝置的控制單元，使第一信號與第二信號於不同時間被指標感測裝置接收，以避免互相干擾而造成指標感測裝置感應錯誤。According to the index control device, system and method disclosed in the present invention, the relative control signal can be outputted by the distance between the first coordinate and the second coordinate induced by the index sensing device, thereby controlling the operation mode of the index. For example, when the indicator control system is in the drawing software, the distance between the first coordinate and the second coordinate can change the mode or the thickness of the brush, or the index control system can compensate for the change of the angle and the index displacement. problem. Therefore, the index control device, system and method disclosed by the present invention can solve the problems of the conventional index control system (ie, the tablet 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 simultaneously received by the index sensing device. When the frequency 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 indicator sensing device at different times by the control unit of the index control device to avoid mutual interference. Causes the indicator sensing device to sense errors.
