Abstract
Description
本發明為一種觸控裝置的手勢辨識方法，係指一種判斷觸碰於觸控裝置上之手勢的辨識方法。The invention provides a gesture recognition method for a touch device, which is a method for determining a gesture of touching a touch device.
觸控裝置的技術與時俱進，觸控裝置可辨識的操作方式也隨之增加，由最早的單指點擊到現有技術的多指點擊。隨著操作複雜度增加，判斷單指或多指的辨識上也時常會因為使用者的習慣而出現誤判。The technology of the touch device keeps pace with the times, and the identifiable operation mode of the touch device is also increased, from the earliest single-finger click to the multi-finger click of the prior art. As the complexity of the operation increases, judging the identification of single or multiple fingers is often misjudged by the user's habits.
以筆記型電腦之鍵盤下方的觸控板為例，該觸控板主要替代滑鼠的功能，來操控螢幕上的游標。但由於觸控板位置與鍵盤較為接近，故使用者在使用鍵盤時，部分手指或手掌可能會不經意地置放於觸控板上，待使用者欲使用觸控板時，原先置放於觸控板的手指或手掌會被誤判為使用者有意的操作，例如使用者欲使用觸控板進行單指點擊動作，但由於原先已將手掌或大拇指置放於觸控板上，故此時的單指點擊將被誤判為多指點擊，而執行了非使用者所欲之操作，因此，現有技術的手勢辨識方法無法判別上述情況，將不便於使用。Take the touchpad below the keyboard of the notebook computer as an example. The touchpad mainly replaces the function of the mouse to control the cursor on the screen. However, since the position of the touchpad is relatively close to the keyboard, some fingers or palms may be inadvertently placed on the touchpad when the user uses the keyboard. When the user wants to use the touchpad, the user first places it on the touchpad. The finger or palm of the control board will be misjudged as the user's intentional operation. For example, the user wants to use the touchpad for single-finger click action, but since the palm or thumb has been placed on the touchpad, this time The single-finger click will be misjudged as a multi-finger click, and the non-user-intended operation is performed. Therefore, the prior art gesture recognition method cannot determine the above situation and will be inconvenient to use.
有鑑於此，本發明研擬不同於以往的手勢辨識方法，以期能解決現有技術的問題。In view of this, the present invention develops a gesture recognition method different from the prior art, in order to solve the problems of the prior art.
為達到上述之發明目的，本發明所採用的技術手段為創作一種觸控裝置的手勢辨識方法，係包括以下步驟： （a）偵測接觸該觸控裝置的物件； （b）偵測到一按壓事件發生； （c）判斷接觸該觸控裝置的物件包含一第一物件及一第二物件； （d）判斷該第一物件與該第二物件中任一物件在該觸控裝置上的位移距離大於一第一位移臨界值； （e）判斷該第一物件與該第二物件之間的距離差小於一間距臨界值； （f）在執行步驟c、d與e之後，送出一多指點擊訊號。In order to achieve the above object, the technical means adopted by the present invention is to create a gesture recognition method for a touch device, which comprises the following steps: (a) detecting an object contacting the touch device; (b) detecting one a pressing event occurs; (c) determining that the object contacting the touch device comprises a first object and a second object; (d) determining that any one of the first object and the second object is on the touch device The displacement distance is greater than a first displacement threshold; (e) determining that the distance difference between the first object and the second object is less than a spacing threshold; (f) after performing steps c, d and e, sending more Refers to the click signal.
進一步而言，若判斷該第一物件與該第二物件在該觸控裝置上的位移距離小於該第一位移臨界值，且判斷該第一物件與該第二物件分別接觸該觸控裝置的時間差小於一預設時間值，則送出一多指點擊訊號。Further, if it is determined that the displacement distance of the first object and the second object on the touch device is less than the first displacement threshold, and determining that the first object and the second object respectively contact the touch device When the time difference is less than a preset time value, a multi-finger click signal is sent.
進一步而言，若判斷該第二物件的位移距離大於該第一位移臨界值，且該第一物件的位移距離小於該第一位移臨界值，則送出一特定鍵點擊訊號。Further, if it is determined that the displacement distance of the second object is greater than the first displacement threshold, and the displacement distance of the first object is less than the first displacement threshold, a specific key click signal is sent.
本發明的優點在於，利用判斷接觸到觸控裝置之物件的時間差或距離差，來減少誤判手勢的情況，有助於提升使用的便利性。The invention has the advantages that the time difference or the distance difference of the object contacting the touch device is used to reduce the misjudgment gesture, which helps to improve the convenience of use.
以下配合圖式及本發明之實施例，進一步闡述本發明為達成預定發明目的所採取的技術手段。The technical means adopted by the present invention for achieving the intended purpose of the invention are further explained below in conjunction with the drawings and the embodiments of the present invention.
請參閱圖1所示，本發明之觸控裝置的手勢辨識方法包含有以下步驟：Referring to FIG. 1 , the gesture recognition method of the touch device of the present invention includes the following steps:
偵測觸碰物件（S1）：偵測觸控裝置上是否有觸碰物件，並記錄觸碰物件在觸控裝置上的狀態，例如觸碰時間點（順序）、觸碰位置、移動距離等。Detecting touch object (S1): detecting whether there is a touch object on the touch device, and recording the state of the touch object on the touch device, such as the touch time point (sequence), touch position, moving distance, etc. .
偵測單擊事件（S2）：當偵測到該觸控裝置發生一按壓事件時，即開始依據步驟S1中所記錄的資訊進行以下步驟的判斷。在一實施例中，該觸控裝置包括一開關設置於一觸控板之下，該按壓事件通常表示該觸控板被下壓而觸動該開關。Detecting a click event (S2): When it is detected that a touch event occurs in the touch device, the following steps are determined according to the information recorded in step S1. In one embodiment, the touch device includes a switch disposed under a touch panel, and the pressing event generally indicates that the touch panel is depressed to touch the switch.
判斷觸碰物件是否包含一第一物件與一第二物件（S3）：若觸碰物件僅包含第一物件，即代表為單指的操作，則進一步執行步驟S4；若觸碰物件包含第一物件及第二物件，即代表為多指的操作，則進一步執行步驟S5。其中第一物件為較早觸碰觸控裝置的物件，第二物件為較晚觸碰觸控裝置的物件。Determining whether the touch object includes a first object and a second object (S3): if the touch object only includes the first object, that is, the operation of the single finger, step S4 is further performed; if the touch object includes the first The object and the second object, that is, the operation representing the multi-finger, further perform step S5. The first object is an object that touches the touch device earlier, and the second object is an object that touches the touch device later.
判斷第一物件的位移距離是否大於一位移臨界值（S4）：該第一物件在觸控裝置上的位移距離若大於一位移臨界值，則送出特定鍵點擊訊號（S41），在一實施例中，這個特定鍵點擊訊號被用於模擬點擊滑鼠左鍵。該第一物件在觸控裝置上的位移距離若小於一位移臨界值，則送出單指點擊訊號（S42），觸控裝置可再根據該單指點擊的位置來決定要執行左鍵指令或右鍵指令。Determining whether the displacement distance of the first object is greater than a displacement threshold (S4): if the displacement distance of the first object on the touch device is greater than a displacement threshold, sending a specific key click signal (S41), in an embodiment In this, the specific key click signal is used to simulate the click of the left mouse button. If the displacement distance of the first object on the touch device is less than a displacement threshold, the single-finger click signal is sent (S42), and the touch device can further determine whether to execute the left-key command or the right button according to the position of the single-finger click. instruction.
判斷任一物件的位移距離是否大於一位移臨界值（S5）：任一物件在觸控裝置上的位移距離若小於一位移臨界值，則進一步執行步驟S6；任一物件在觸控裝置上的位移距離若大於一位移臨界值，則進一步執行步驟S7。其中步驟S4與步驟S5中的位移臨界值可為相同數值或不同數值。Determining whether the displacement distance of any object is greater than a displacement threshold (S5): if the displacement distance of any object on the touch device is less than a displacement threshold, step S6 is further performed; any object is on the touch device. If the displacement distance is greater than a displacement threshold, step S7 is further performed. The displacement thresholds in step S4 and step S5 may be the same value or different values.
判斷第一物件與第二物件的接觸時間差是否大於預設時間值（S6）：藉由比較該第一物件接觸該觸控裝置的時間點與該第二物件接觸該觸控裝置的時間點可以獲得上述的接觸時間差，該第一物件與該第二物件接觸觸控裝置的時間差距若小於預設時間值，則送出多指點擊訊號（S61）；該第一物件與該第二物件接觸觸控裝置的時間差距若大於預設時間值，送出單指點擊訊號（S62），觸控裝置可再視該單擊事件的發生位置來決定要執行左鍵指令或右鍵指令。如果先觸碰的第一物件為閒置在觸控裝置上的觸碰物件，而第二物件明顯比第一物件晚觸碰觸控裝置，這意謂著第二物件可能才是使用者有意的操作。因此，利用第二物件與第一物件的接觸時間差，有助於確認使用者想進行的操作是多指操作還是單指操作，進而提昇手勢判斷的準確性。Determining whether the contact time difference between the first object and the second object is greater than a preset time value (S6): by comparing a time point at which the first object contacts the touch device with a time point at which the second object contacts the touch device Obtaining the contact time difference, if the time difference between the first object and the second object contacting the touch device is less than the preset time value, sending the multi-finger click signal (S61); the first object contacting the second object If the time difference of the control device is greater than the preset time value, the single-finger click signal is sent (S62), and the touch device can determine the execution position of the click event to determine whether to execute the left-click command or the right-click command. If the first object touched first is a touch object that is idle on the touch device, and the second object is obviously touched by the touch device later than the first object, this means that the second object may be intentional to the user. operating. Therefore, the difference in contact time between the second object and the first object helps to confirm whether the operation that the user wants to perform is a multi-finger operation or a single-finger operation, thereby improving the accuracy of the gesture determination.
在步驟S7中，判斷是否第二物件的位移距離大於位移臨界值，且第一物件的位移距離小於位移臨界值?。如果第二物件的位移距離大於位移臨界值，而第一物件的位移距離小於位移臨界值，則送出特定鍵點擊訊號（S71），在一實施例中，這個特定鍵點擊訊號被用於模擬點擊滑鼠左鍵。如果步驟S7的判斷為否，也就是至少第一物件的位移距離大於位移臨界值，則進一步執行步驟S8。In step S7, it is determined whether the displacement distance of the second object is greater than the displacement threshold, and the displacement distance of the first object is less than the displacement threshold. If the displacement distance of the second object is greater than the displacement threshold, and the displacement distance of the first object is less than the displacement threshold, a specific key click signal is sent (S71). In an embodiment, the specific key click signal is used to simulate the click. Left mouse button. If the determination of step S7 is NO, that is, at least the displacement distance of the first object is greater than the displacement threshold, step S8 is further performed.
判斷第一、第二物件之間的距離差是否大於一間距臨界值（S8）。步驟S8是判斷按壓事件發生時，在觸控裝置上的第一物件的位置與第二物件的位置之間，其距離差是否大於間距臨界值，。若大於間距臨界值，則送出單指點擊訊號（S81）；若小於間距臨界值，則送出多指點擊訊號（S82）。在按壓事件發生時，根據一般使用者的習慣，如果使用者是有意的進行多指的點擊操作，第一物件與第二物件之間的距離應該不會太大。因此，在按壓事件發生時，根據第二物件與第一物件之間的距離，有助於確認使用者想進行的操作是多指操作還是單指操作，進而提昇手勢判斷的準確性。It is determined whether the difference in distance between the first and second objects is greater than a distance threshold (S8). Step S8 is to determine whether the distance difference between the position of the first object on the touch device and the position of the second object is greater than the distance threshold when the pressing event occurs. If it is greater than the threshold value, a single-finger click signal is sent (S81); if it is smaller than the spacing threshold, a multi-finger click signal is sent (S82). When the pressing event occurs, according to the habit of the general user, if the user intentionally performs a multi-finger click operation, the distance between the first object and the second object should not be too large. Therefore, when the pressing event occurs, according to the distance between the second object and the first object, it is helpful to confirm whether the operation that the user wants to perform is a multi-finger operation or a single-finger operation, thereby improving the accuracy of the gesture determination.
步驟S4及S5的位移距離係對應第一或第二物件在按壓事件發生之前的移動，在上述實施例中，係在判斷發生按壓事件之後，根據該第一及第二物件在按壓事件之前在觸控裝置上的移動而判斷出第一與第二物件的位移距離。在其他實施例中，也可以先計算第一或第二物件移動的位移距離，若判斷累計的位移距離超過該位移臨界值之後，偵測到發生按壓事件，則執行步驟S8。換言之，在本發明的方法中，判斷第一或第二物件的位移距離可以是在按壓事件發生之後或之前進行。以下運用數個具體實施例來加以說明本發明之手勢辨識方法，僅為具體說明而非用以限制本發明：The displacement distances of steps S4 and S5 correspond to the movement of the first or second object before the pressing event occurs. In the above embodiment, after determining that the pressing event occurs, according to the first and second objects before the pressing event The displacement of the first and second objects is determined by the movement on the touch device. In other embodiments, the displacement distance of the movement of the first or second object may be calculated first. If it is determined that the accumulated displacement distance exceeds the displacement threshold, and a pressing event is detected, step S8 is performed. In other words, in the method of the present invention, determining the displacement distance of the first or second object may be performed after or before the pressing event occurs. The following describes the gesture recognition method of the present invention by using a few specific embodiments, which are merely illustrative and not intended to limit the present invention:
實施例 1 請參閱圖2所示，觸控裝置10上已先存在使用者閒置之手掌20，此時使用者之另一手指30點擊觸控裝置10欲進行單指點擊操作，實際上使用者的手掌20並非其所欲用以執行操作的物件，由於觸控裝置10上偵測到手掌20及手指30兩個物件，兩物件均未進行移動，且手掌20已閒置於觸控裝置10上一段時間，與手指30接觸觸控裝置10的時間有一定的時間差，故此時手指30在觸控裝置上的按壓將視為單指點擊事件，而觸控裝置10將執行單指點擊指令。See Example 1 shown in FIG, 10 is already pre-existing idle user touch device 202 of the palm, the finger 30 at this time another user clicks the touch device 10 to be a single finger tap operation, a user actually The palm 20 is not the object for performing the operation. Since the two objects of the palm 20 and the finger 30 are detected on the touch device 10, the two objects are not moved, and the palm 20 is idle on the touch device 10. For a period of time, there is a certain time difference between the time when the finger 30 is in contact with the touch device 10. Therefore, the pressing of the finger 30 on the touch device will be regarded as a single-finger click event, and the touch device 10 will execute a single-finger click command.
實施例 2 請參閱圖3所示，使用者同時使用兩隻手指30點擊觸控裝置10欲進行點擊操作，實際上使用者係欲以兩隻手指30執行操作，由於觸控裝置10上辨識到兩隻手指30，兩隻手指30均未進行移動且為同時或僅具有微小的時間差對觸控裝置進行按壓，故此時兩隻手指30的按壓動作將視為多指點擊事件，而觸控裝置10將執行多指點擊指令。 Example 2 Referring to FIG. 3, the user 30 clicking while using two fingers touch device 10 to be performed the click operation, the operation is actually performed based user trying to use two fingers 30, since the touch device 10 to identify The two fingers 30 and the two fingers 30 are not moved and the touch device is pressed at the same time or only with a slight time difference, so the pressing action of the two fingers 30 will be regarded as a multi-finger click event, and the touch device 10 will execute the multi-finger click command.
實施例 3 請參閱圖4所示，觸控裝置10上已先存在使用者閒置之手掌20，此時使用者之另一手指30於觸控裝置10上滑移一定距離後並按壓觸控裝置10欲進行特定操作，實際上使用者的手掌20並非其所欲用以執行操作的物件，而使用者係欲以手指30操控游標移動後，執行特定鍵點擊指令，由於觸控裝置10上辨識到手掌20及手指30兩個物件，兩物件中為較晚觸碰到觸控裝置10的手指30進行移動，而先碰觸的手掌20並未明顯移動，故此時手指30的按壓動作將視為特定鍵點擊事件，而觸控裝置10將執行特定鍵點擊指令。See Example 3 as shown in FIG, 10 is already pre-existing idle user's palm touch device 204, the user at this time another finger 30 sliding on a distance from the touch device 10 and the touch device is pressed 10 In order to perform a specific operation, the user's palm 20 is not actually the object for performing the operation, and the user wants to perform the specific key click command after the cursor 30 is manipulated by the finger 30, because the touch device 10 recognizes The two objects of the palm 20 and the finger 30 are moved by the finger 30 that touches the touch device 10 at a later time, and the palm 20 that is touched first does not move significantly, so the pressing action of the finger 30 will be regarded as the pressing action. For a particular key click event, the touch device 10 will execute a particular key click command.
實施例 4 請參閱圖5所示，使用者先以第一手指31在觸控裝置10上滑移一定距離後，隨後再以第二手指32按壓觸控裝置10之特定位置，實際上使用者係以第一手指31將游標移動至特定位置後，再以第二手指32按壓觸控裝置以執行該特定位置所對應之單鍵指令，由於觸控裝置10上偵測到到兩隻手指31、32，第二手指32並未移動，第一手指31明顯移動，但第一手指31與第二手指32的間距過大，故此時第二手指32的按壓將視為單指點擊事件，而觸控裝置10將執行單指點擊指令。 Example 4 Referring to FIG. 5, the first user 31 to slip after a certain distance on the touch device 10, followed by pressing the finger 32 to a second specific position of the touch device 10, in fact, the user first finger After the cursor is moved to the specific position by the first finger 31, the touch device is pressed by the second finger 32 to execute the single button command corresponding to the specific position, because the two fingers 31 are detected on the touch device 10. 32, the second finger 32 does not move, the first finger 31 moves obviously, but the distance between the first finger 31 and the second finger 32 is too large, so the pressing of the second finger 32 will be regarded as a single-finger click event. The control device 10 will execute a single finger click command.
實施例 5 請參閱圖6所示，使用者先以第一手指31在觸控裝置10上滑移一定距離後，再放上第二手指32，並透過第二手指32在相鄰第一手指31的位置按壓觸控裝置10，實際上使用者係以第一手指31將游標移動至特定位置後，再以第一手指31及第二手指32按壓觸控裝置而欲產生多指點擊效果，由於觸控裝置10上偵測到兩隻手指31、32，第二手指32並未移動，第一手指31明顯移動，且在按壓事件發生時，第二手指32相鄰於第一手指31，故此操作將被視為多指點擊事件，而觸控裝置10將執行多指點擊指令。See Example 5 shown in FIG. 6, the user first after the first finger 31 a distance in the sliding touch device 10, and put on the second finger 32, and through a second finger adjacent to the first finger 32 The position of 31 presses the touch device 10, and the user actually moves the cursor to a specific position with the first finger 31, and then presses the touch device with the first finger 31 and the second finger 32 to generate a multi-finger click effect. Since the two fingers 31, 32 are detected on the touch device 10, the second finger 32 does not move, the first finger 31 moves significantly, and when the pressing event occurs, the second finger 32 is adjacent to the first finger 31. Therefore, the operation will be regarded as a multi-finger click event, and the touch device 10 will execute a multi-finger click command.
實施例 6 請參閱圖7所示，使用者之手指30於觸控裝置10上滑移一定距離後並按壓觸控裝置10欲進行特定操作，實際上使用者係欲以手指30操控游標移動後，執行特定鍵點擊指令，由於觸控裝置10上僅辨識到手指30此單一物件，且手指30進行移動後按壓觸控板，故此時手指30的按壓將視為特定鍵點擊事件，而觸控裝置10將執行特定鍵點擊指令。 Example 6 After see FIG. 7, the user's finger 30 after a certain distance on the touch slide 10 and means 10 to be pressed against the touch device for a specific operation, in fact, the user trying to use the finger-based control cursor 30 The specific key click command is executed. Since the touch device 10 recognizes only the single object of the finger 30 and the finger 30 moves and presses the touch panel, the pressing of the finger 30 will be regarded as a specific key click event, and the touch is performed. Device 10 will execute a particular key click command.
實施例 7 請參閱圖8所示，使用者之手指30按壓觸控裝置10欲進行特定操作，實際上使用者係欲執行該特定位置的單鍵點擊指令，由於觸控裝置10上僅辨識到手指30此單一物件，且手指30未移動，故此時手指30的按壓將視為單指點擊事件，而觸控裝置10將執行單指點擊指令。 Example 7 Referring to FIG. 8, the user's finger 30 presses the touch device 10 to be a particular operation, in fact, a single button click command to be the user train the particular location is performed, since the touch device 10 to recognize only The finger 30 is a single object, and the finger 30 is not moved, so the pressing of the finger 30 at this time will be regarded as a single-finger click event, and the touch device 10 will execute a single-finger click command.
綜上所述，本發明的手勢辨識方法，可以藉由判斷時間差或距離差的方式，來識別使用者真正想要進行的手勢操作，，以使得所辨識獲得的指令能更準確的命中使用者所欲下達的指令，提高觸控操作的準確度，進而增加使用便利性。In summary, the gesture recognition method of the present invention can identify the gesture operation that the user really wants to perform by judging the time difference or the distance difference, so that the recognized instruction can hit the user more accurately. The instructions to be issued improve the accuracy of the touch operation and increase the convenience of use.
在以上的實施例中，修改各步驟的順序是可能的，並且仍可以達到相同的手勢判斷結果。以上所述僅是本發明的實施例而已，並非對本發明做任何形式上的限制，雖然本發明已以實施例揭露如上，然而並非用以限定本發明，任何所屬技術領域中具有通常知識者，在不脫離本發明技術方案的範圍內，當可利用上述揭示的技術內容作出些許更動或修飾為等同變化的等效實施例，但凡是未脫離本發明技術方案的內容，依據本發明的技術實質對以上實施例所作的任何簡單修改、等同變化與修飾，均仍屬於本發明技術方案的範圍內。In the above embodiments, it is possible to modify the order of the steps, and the same gesture judgment result can still be achieved.
