請參閱圖6配合圖2及圖5所示，以一個工作週期為例，該輸入裝置20之電極單元23’接收到來自該觸控裝置10之觸控電極111所發送的上行訊號S_up ，該上行訊號S_up 中包含有代表該發送時間的時間戳記S_t1 ，該觸控裝置10之觸控電極111隨後進入接收模式RX，準備經由該觸控電極111接收來自該輸入裝置20之電極單元23的訊號。該輸入裝置20接收上行訊號S_up 後，在該工作週期中依據該上行訊號S_up 中的同步資訊透過該電極單元23間隔發送第一下行訊號S_down1 、第二下行訊號S_down2 、第三下行訊號S_down3 ，以供該觸控裝置10之觸控電極111在該工作週期中接收，進而利用該些下行訊號S_down1 、S_down2 、S_down3 來判斷該輸入裝置20相對於該觸控裝置10上的位置，該些下行訊號S_down1 、S_down2 、S_down3 除了可供該觸控裝置10判斷該輸入裝置20之位置的訊號之外，或者也能包含有該輸入裝置的相關資訊，例如：識別ID等；另外，同樣在該工作週期中，該輸入裝置20之無線通訊單元24間隔發送第一伴隨資訊S_side1 、第二伴隨資訊S_side2 、第三伴隨資訊S_side3 ，以供該觸控裝置10之無線通訊單元13接收，該些伴隨資訊可為前述之壓力資訊、傾斜角資訊或按鍵資訊等。而且，該第一伴隨資訊S_side1 包含有第一時間戳記S_t1-1 、該第二伴隨資訊S_side2 包含有第二時間戳記S_t1-2 、該第三伴隨資訊S_side3 包含有第三時間戳記S_t1-3 ，該第一、第二及第三時間戳記S_t1-1 、S_t1-2 、S_t1-3 、均包含有對應該工作週期之上行訊號S_up 中所包含的時間戳記S_t1 、並另包含該筆伴隨資訊的順序戳記。Please refer to FIG. 6 in conjunction with FIG. 2 and FIG. 5. Taking a working cycle as an example, the electrode unit 23' of the input device 20 receives the uplink signal S _up sent by the touch electrode 111 of the touch device 10. The uplink signal S _up includes a time stamp S _t1 representing the sending time, and the touch electrode 111 of the touch device 10 then enters the receiving mode RX, ready to receive the electrode unit from the input device 20 via the touch electrode 111 23 signal. After the input device 20 receives the uplink signal S _up , it sends the first downlink signal S _down1 , the second downlink signal S _down2 , and the third downlink signal S _down1 , the second downlink signal S _down2 , and the third through the electrode unit 23 at intervals according to the synchronization information in the uplink signal S _up in the working cycle. The downstream signal S _down3 is for the touch electrode 111 of the touch device 10 to receive during the work cycle, and the downstream signals S _down1 , S _down2 and S _{down3 are} used to determine whether the input device 20 is relative to the touch device 10, the downstream signals S _down1 , S _down2 , and S _down3 can _not only be used by the touch device 10 to determine the position of the input device 20, or can also contain relevant information of the input device, for example : identification ID; Further, also in this working cycle, the wireless communication unit 20 transmits the input means 24 spaced along a first information S _side1, along with the second information S _side2, along with third information _S side3, for the contact The wireless communication unit 13 of the control device 10 receives the accompanying information, which may be the aforementioned pressure information, tilt angle information, or button information. Moreover, the first accompanying information S _side1 includes a first time stamp S _t1-1 , the second accompanying information S _side2 includes a second time stamp S _t1-2 , and the third accompanying information S _side3 includes a third time stamp _S t1-3, the first, second and third timestamp _{_{_{S t1-1, S t1-2, S t1-3}}} , each time it should contain S _up an uplink signal included in the duty cycle of the stamp S _t1 , and additionally contains the sequence stamp of the accompanying information.

當該觸控裝置10接收到前述下行訊號S_down1 、S_down2 、S_down3 後，會將其填入韌體中相對應該工作週期的紀錄位置，例如若該觸控裝置10在一第一工作週期傳送該上行訊號S_up ，則該觸控裝置10在該第一工作週期接收到該下行訊號S_down1 、S_down2 、S_down3 後，會將其填入韌體中對應該第一工作週期的紀錄位置；另外，當該觸控裝置10接收到該伴隨資訊S_side1 、S_side2 、S_side3 後，則會依據該伴隨資訊S_side1 、S_side2 、S_side3 所包含的時間戳記S_t1 ，將其填入韌體中與該時間戳記S_t1 相對應之該第一工作週期的其他紀錄位置，藉此紀錄該工作週期中該輸入裝置20的座標、壓力資訊、按鍵資訊、ID等，待資訊整合後，會再將整合後內容傳送給該主機102。When the touch device 10 receives the aforementioned downlink signals S _down1 , S _down2 , and S _down3 , it will fill in the record position corresponding to the duty cycle in the firmware. For example, if the touch device 10 is in a first duty cycle After transmitting the uplink signal S _up , the touch device 10 receives the downlink signals S _down1 , S _down2 , and S _down3 in the first duty cycle, and fills them in the firmware corresponding to the record of the first duty cycle position; Further, when the touch device 10 after receiving the associated information _S _side1, S _side2, S side3, will be according to the accompanying information _S _side1, S _side2, S side3 contains timestamp S _t1, which is filled Into the firmware corresponding to the time stamp S _t1 in other recording positions of the first working cycle, so as to record the coordinates, pressure information, key information, ID, etc. of the input device 20 in the working cycle. After the information is integrated , The integrated content will be sent to the host 102 again.

由於該輸入裝置20之無線通訊單元24在傳遞該伴隨資訊S_side 時可能因訊號的延遲而導致該觸控裝置10的無線通訊單元13並非在該同一工作週期中收到該伴隨資訊S_side ，以圖6所示之實施態樣為例，該第三伴隨資訊S_side3 在下一工作週期才由該觸控裝置10的無線通訊單元13接收到，但由於該第三伴隨資訊S_side3 中已包含該第三時間戳記S_t1-3 ，故該觸控裝置10仍可透過該第三時間戳記S_t1-3 辨別此時所收到的該第三伴隨資訊S_side3 屬於哪一個工作週期，因此該觸控裝置10在將該第三伴隨資訊S_side3 填入韌體時，不會因為接收到該伴隨資訊S_side 當下的工作週期已非原工作週期而將相關訊息記錄到錯誤位置。Since the wireless communication unit 20 of the input device 24 may vary along the signal transfer delay caused by the wireless communication unit 10 of the touch device 13 is not received at the S _side information accompanying the information during the same work cycle S _side, Taking the implementation aspect shown in FIG. 6 as an example, the third accompanying information S _{side3 is received} by the wireless communication unit 13 of the touch device 10 in the next working cycle, but because the third accompanying information S _side3 already contains The third time stamp _St1-3 , so the touch device 10 can still use the third time stamp _{St1-3 to} identify which duty cycle the third accompanying information S _side3 received at this time belongs to. Therefore, the When the touch device 10 fills the third accompanying information S _side3 into the firmware, it will not record related information to the wrong location because the current work cycle of receiving the accompanying information S _side is not the original work cycle.

因此，透過前述時間戳記S_t 的使用，可有效確保該伴隨資訊S_side 能和相對應時間的下行訊號S_down 結合運用，則使用者的操作能被正確的呈現，避免因無線傳輸的延遲而造成資料遺失或漏墨的情況發生。Therefore, through the use of the aforementioned time stamp S _t , it can be effectively ensured that the accompanying information S _side can be used in conjunction with the corresponding time downlink signal S _down , and the user's operation can be correctly presented, avoiding the delay of wireless transmission. A situation that causes data loss or ink leakage occurs.

That is, the downstream signal S _down further includes a contact message S _c . In one embodiment, the contact sensor 25 is the pressure sensor, and when the pressure value sensed by the contact sensor 25 is greater than a threshold value (for example, the threshold value is 0), the input device 20 is determined The contact terminal 211 is in contact with the touch device 10, and vice versa.

當該輸入裝置20之接觸端211接觸該觸控裝置10時，該接觸訊息S_c 呈現為一第一訊息；當該輸入裝置20之接觸端211未接觸該觸控裝置10時，該接觸訊息S_c 呈現為一第二訊息；該第一訊息與該第二訊息不同，譬如可分別為0及1。該觸控裝置10可藉由所接收到的下行訊號S_down 中包含的該接觸訊息S_c ，來得知該輸入裝置20之接觸端211是否接觸到該觸控裝置10。在一實施樣態中，可透過所接收到的該接觸訊息S_c 及先前所接收到的伴隨資訊S_side ，來推算出一模擬伴隨資訊S_side ^* ，進而透過該模擬伴隨資訊S_side ^* 來維持使用者體驗。舉例而言，當該觸控裝置10之無線通訊單元13在第1～5工作週期均正常皆收到該伴隨資訊S_side ，但在第6工作週期未收到該伴隨資訊S_side 時，透過在第6工作週期所接收到的該接觸訊息S_c 及在前面至少一個工作週期所接收到的伴隨資訊S_side ，來決定一模擬伴隨資訊S_side ^* ，例如直接採用第5工作週期的壓力值或第3、4、5工作週期的平均壓力值來作為第6工作週期的壓力值(亦即該模擬伴隨資訊S_side ^* )，又或者利用前面數個工作週期之伴隨資訊中的壓力值配合速度當作權重值來計算第6週期的壓力值，其中速度與壓力值權重成反比。When the contact end 211 of the input device 20 contacts the touch device 10, the contact message _{Sc is} presented as a first message; when the contact end 211 of the input device 20 does not contact the touch device 10, the contact message S _{c is} presented as a second message; the first message is different from the second message, such as 0 and 1, respectively. The touch device 10 may be contacted by the message received by the S _c S _down downstream signal included in the input to that apparatus 20 of the contact terminal 211 is in contact to the touch device 10. In an implementation mode, the received contact information _Sc and the previously received accompanying information S _side can be used to calculate a simulated accompanying information S _side ^* , and then through the simulated accompanying information S _side ^* Maintain user experience. For example, when the wireless communication unit 13 of the touch device 10 normally receives the accompanying information S _side in the first to fifth working cycles, but does not receive the accompanying information S _side in the sixth working cycle, through working sixth cycle received the contacts message S _c, and in front of the at least one duty cycle of the received associated information S _side, determines a simulated accompanying information S _side ^*, for example, directly from the pressure value the fifth work cycle Or the average pressure value of the 3rd, 4th, and 5th working cycle as the pressure value of the 6th working cycle (that is, the simulation accompanying information S _side ^* ), or using the pressure value in the accompanying information of the previous several working cycles to match Speed is used as the weight value to calculate the pressure value of the 6th cycle, where the speed is inversely proportional to the weight of the pressure value.

該下行訊號S_down 中所包含之該接觸訊息S_c 可透過不同方式來呈現。在一實施例中（如圖8所示），該下行訊號S_down 中包含有一燈塔訊息S_beacon 及該接觸訊息S_c ，則在該輸入裝置20之接觸端211接觸該觸控裝置10時，該接觸訊息S_c 以該第一訊息呈現；在無接觸時，該接觸訊息S_c 以該第二訊息呈現。在另一實施例中（如圖9所示），該下行訊號S_down ^# 包含有一燈塔訊息S_beacon ^＃，該燈塔訊息S_beacon ^＃以不同頻率來呈現該接觸訊息S_c ，在有接觸時，該燈塔訊息S_beacon ^＃以一第一頻率呈現；在無接觸時，該燈塔訊息S_beacon ^＃則以一第二頻率呈現。The downlink signal S _down the contacts included in the message S _c can be presented in different ways. In one embodiment (FIG. 8), the downstream signal S _down a beacon message contains the contacts and S _beacon message S _c, the contacts 211 of the touch device 10 is at the contact end 20 of the input device, S _c of the contact post is presented in the first message; in the absence of contact of the contact post S _c presented with the second message. In another embodiment (as shown in Figure 9), the downlink signal S _down ^# includes a beacon message S _beacon ^# , and the beacon message S _beacon ^# presents the contact information S _c with different frequencies. When there is contact, The beacon message S _beacon ^# is presented with a first frequency; when there is no contact, the beacon message S _beacon ^# is presented with a second frequency.

因此，無論是否具有無線通訊單元、或在無線通訊單元失效的狀態下，該觸控裝置10均能藉由該接觸訊息S_c 來獲悉該輸入裝置20是否有接觸到該觸控裝置10，並能進一步透過演算法模擬該輸入裝置20對應於該觸控裝置10之壓力及其他可能的伴隨資訊。Thus, whether or not having wireless communication unit, or in the state of the wireless communication unit fails, the touch device 10 by this contact can be learned message S _c of the input device 20 is to contact the touch device 10, and The pressure of the input device 20 corresponding to the touch device 10 and other possible accompanying information can be further simulated through an algorithm.
