VI. Description of the invention: [Technical field of the invention] _] The method for recognizing gestures and the touch module of the method, in particular, the declination of continuous displacement units generated according to gestures 'The accumulated non-linear indicators are used as the basis for gestures and gestures. They are widely used as touch modules for multi-touch input on various electronic devices. [Prior Art] 〇[_ With the advancement of touch technology, the traditional sliding function of the touchpad has been widely used in various electronic devices. _In addition, the conventional touchpad replaces the traditional mouse by performing a function of detecting an object (such as a finger) sliding on the surface thereof to perform a function of moving the cursor or clicking on a specific item displayed on the screen. use. [0003] However, as the additional functions of electronic products become more and more complicated, if the cursor movement of the conventional touch panel and the control method such as option selection are still used, it will inevitably greatly increase the complexity of the operation program. Not only does it increase the difficulty of control, but it also reduces the user's willingness to use it. [0004] To reduce the complexity of the operating procedure, there are different gestures to perform the corresponding input functions. In practice, this type of manipulation must preset the cut-in, jump-out mode, and the corresponding connection of gestures to specific functions. In other words, according to the trajectory of the slide on the touchpad, special gestures such as: click, double-click, drag window scroll, window zoom, window rotation, etc. in the window system are recognized. [0005] However, in practice, this method still has the following disadvantages. First, the cut-in and pop-out modes will increase the complexity of the control; its__, #099119596 Form No. A0101 Page 3 of 30' 201145097 As the number of gestures increases, the user must memorize the correspondence between gestures and specific manipulation capabilities, and the number of gesture determination loops and comparison circuits must also increase, which also wastes computational space and takes up circuit design space. Make the electronic device more power-hungry. [0006] With regard to the aforementioned cut-in and jump-out modes, there is also a use of the touchpad surface to draw a separate area for the manipulation of specific functions. In the case of page scrolling, for example, a specific area can be segmented on the surface of the touchpad. When the user uses a specific gesture to control the specific area, the page can be scrolled for browsing. However, this type of manipulation can only be applied to the scrolling of the page in the vertical direction, and the effect on the control efficiency is not satisfactory. In view of the above, in order to improve the above disadvantages, the inventors of the present invention propose a method for analyzing a two-dimensional trajectory to generate at least one non-linear index and a touch module using the same; thereby, the user can utilize Simple gestures, multi-function manipulation, and optimized touch operation efficiency. SUMMARY OF THE INVENTION [0008] The main objective of the present invention is to provide a method for analyzing a two-dimensional representation to generate at least one non-linear index and a touch module using the same, whereby the user can use a simple gesture. Control a variety of functions to optimize touch operation efficiency. [0009] In order to achieve the above object, the present invention provides a method for analyzing a two-dimensional trajectory to generate at least one non-linear index, comprising the steps of: capturing a two-dimensional trajectory, wherein the two-dimensional trajectory is sorted with time. a two-dimensional coordinate position; sequentially generating a plurality of displacement units according to the two-dimensional trajectory, wherein each displacement unit includes a displacement amount and a displacement direction of the two-dimensional trajectory moved within a predetermined time interval; The displacement of the displacement unit is compared with a reference value of a 099119596 form number A0101, page 4 of 30, 201145097; when the displacement of the displacement unit is greater than the reference value, the displacement direction of the displacement unit and the previous sequence displacement are calculated. The angle formed by the displacement direction of the unit; the angle is sequentially accumulated to obtain a cumulative angle, wherein the cumulative angle includes an accumulated value and a positive sign; and the integrated angle is converted into at least one non-linear index. [0010] In addition, the present invention also provides a touch module including a sensing surface and a controller. The sensing surface is distributed on the surface with a plurality of proximity sensors for sensing contact of at least one object on the sensing surface. The controller is electrically connected to the plurality of proximity sensors for determining a first array displacement and a second displacement of each of the objects sliding on the sensing surface, and calculating a second displacement between each group and the first displacement An angle formed by accumulating the included angles at an accumulated angle, and outputting at least one non-linear index according to the integrated angle; wherein, the second displacement of each group is determined after the first displacement, and the cumulative angle includes a cumulative The value is a plus sign. [0011] In implementation, the touch module detects a contact position and a contact time of the object on the sensing surface, and determines the nonlinear index according to the contact position, the contact time, and the cumulative angle. [0012] For a better understanding of the features and functions of the present invention, the embodiments are described in detail below with reference to the drawings. [Embodiment] [0013] Referring to Figure 1, there is shown a flow chart of a method of analyzing a two-dimensional trajectory of the present invention to produce at least one non-linear index. [0014] In step A1, as shown in FIG. 2, a two-dimensional trajectory 10 is first captured, and the two-dimensional trajectory 10 is a two-dimensional coordinate position sorted with time, including 099119596 form number A0101, page 5 / A total of 30 pages 0992034670-0 201145097 together point 1 0 2 and an end point 1 0 4; the aforementioned two-dimensional coordinate system can be described by different coordinate systems (such as right angle coordinate system or cylindrical coordinate system); in other words, the contact induction The point on the surface is the origin. The two-dimensional trajectory 10 represents that the user utilizes an object (such as a finger) to slide at least a part of the trajectory on a contact sensing surface; that is, the captured two-dimensional trajectory is when any one of the sliding trajectories is gliding. Inward. [0015] In addition, in the aspect of initiating the capture of the two-dimensional representation, the following modes may be utilized: First, when the object is detected to contact the contact sensing surface for the first time, the two-dimensional trajectory is captured; Second, when it is detected that the object continuously contacts the contact sensing surface for a certain period of time (preset time), the party begins to capture the two-dimensional trajectory; and third, when detecting that the object contacts the specific area of the contact sensing surface (preset Time), the party begins to capture the two-dimensional trajectory. [0016] In step Α2, as shown in FIG. 3, a plurality of displacement units 12 are sequentially generated according to the two-dimensional representation 10, wherein each displacement unit 12 includes the two-dimensional trajectory 10 at a preset time. The amount of displacement moved within the distance and its direction of displacement. The time of occurrence of each displacement unit 12 shown in FIG. 3 is not repeated with each other. However, the displacement unit implementation range of the present invention should not be limited thereto, and the order of occurrence of each displacement unit 12 is related to each other. However, the time of occurrence is reproducible with each other, that is, the end time of the displacement unit of the previous sequence may be later than the start time of the displacement unit of the subsequent sequence. [0017] Subsequently, in step A3, the displacement amount of each displacement unit 12 is sequentially compared with a reference value segment 14; when the displacement amount of the displacement unit 12 is greater than the length of the reference value segment 14, the square calculation The angle formed by the displacement direction of the displacement unit and the displacement direction of the previous sequential displacement unit. Accordingly, when it is judged that the displacement amounts of the displacement units 120, 122, and 124 are all greater than the reference value, 099119596, the form number Α0101, the sixth page, the total of 30 pages, 0992034670-0, 201145097, that is, the calculation of the aforementioned displacement units 120 and 122 and 122 The angle between 0 and 124 is 0 1 and 0 2 . Finally, in steps A4 and A5, the aforementioned angles are sequentially accumulated to obtain an integrated angle; wherein the cumulative angle includes an accumulated value and a plus sign: and the accumulated angle is converted into at least one non-linear index. In the present embodiment, as shown in Fig. 3A, wherein the counterclockwise direction is preset to a positive angle, the angles of Θ1 and 02 are both positive values. [0019] In addition, the conversion of the foregoing non-linear index can be achieved in many ways; for example, a threshold can be preset, and when the accumulated value of the accumulated angle exceeds the threshold, the non-converted according to the sign is converted A linear index; alternatively, a formula may be utilized to convert the aforementioned cumulative angle into the aforementioned non-linear index. The aforementioned non-linear indicators represent the corresponding control signals for the manipulation of specific functions. [0020] In addition, the present invention also provides a touch module. Please refer to FIG. 4, which is a structural diagram showing the first embodiment of the touch module. [0021] As shown in the figure, in the first embodiment, the touch module 2 includes an inductive surface 20 and a controller 22. The sensing surface 20 is disposed on the surface of the plurality of proximity sensors 202 and is provided with a plurality of sensing regions; wherein the proximity sensor 202 is configured to sense contact of at least one object (eg, a finger) on the sensing surface 20. The controller 22 is electrically connected to the plurality of proximity sensors 202 and has a capture unit 220, a processing unit 222, a calculation unit 224, a conversion unit 226, and a detection unit 228. [0022] The above-mentioned capturing unit 220 is configured to capture the two-dimensional trajectory 10 (as shown in FIG. 2). 099119596 Form No. A0101 Page 7/Total 30 Page 0992034670-0 201145097 'The two-dimensional trajectory 10 captured is The processing unit 222 sequentially processes the first and second displacements of the riding array, wherein the second displacement of each group is determined after the far-first displacement; subsequently, the calculation unit 224 can calculate the first in each group. And the angle between the two displacements and the first displacement, and accumulating the angles between the cumulative angles, wherein the cumulative angle includes - the cumulative value and a positive and negative sign; finally, using the foregoing converting unit 226, according to the aforementioned cumulative angle At least one non-linear indicator 24 is output.

In addition, the first displacement of each of the foregoing groups is the difference in position of the object contacting the sensing surface at two time points, and the second displacement of each group is the difference in position of the object contacting the sensing surface between the other two time points. 'And the time point of the first displacement is later than the first-displacement time point. As described above, the foregoing conversion unit 226 can utilize various methods to achieve the purpose of converting the cumulative angle and outputting the non-linear index; for example, the threshold can be preset - when the accumulated angle is accumulated: light_the threshold, That is, the aforementioned non-linear index is converted according to the sign; or the _ formula is used to convert the aforementioned cumulative angle into the aforementioned non-linear index.

Please refer to the 5th to 5th® ’ display for the use of the above touch module. As shown in FIG. 5, the sensing surface 2 is provided with four sensing regions 2040, 2042, 2044, and 2046. In operation, the controller (not shown) is assigned according to the starting position of the one-dimensional trajectory. The sensing area is used to determine which nonlinear index is generated. In the implementation, as shown in the fifth to fifth figures, the user can use the touch module 'on the screen 30 of an electronic device 3 to control the following four functions: the page scrolls vertically, and the page scrolls horizontally. , image rotation and image enlargement / reduction. As shown in FIG. 5, the sensing area 2046 above the sensing surface 20 is preset to manipulate the scrolling of the display screen in the vertical direction, and the object first contacts the sensing area 2046 and then slides out a two-dimensional trajectory; When the accumulated value of the two-dimensional trajectory exceeds a threshold, the sign of the cumulative angle is converted into a control signal that can scroll down or up on the screen 30. Similarly, the sign of the cumulative angle can also be converted into a control signal that can scroll down the page displayed on the screen 3 or scroll up one page, or move the display displayed on the screen 30 upward. , the item displays or the control signal displayed next time. Figure 5C shows the manipulation of another function, wherein the sensing area 2044 on the left side of the sensing surface 20 is preset to manipulate the display screen in the horizontal direction of the scroller 099119596 Form No. 1010101 Page 9 / Total 30 Page 0992034670-0 [0031] 201145097 and the object first contacts the sensing area 2044 and then slides out a two-dimensional trajectory; when the cumulative value exhibited by the two-dimensional trajectory exceeds a threshold value, the positive and negative signs of the cumulative angle are respectively converted into控制 Control signals that scroll left or right. [0032] Similarly, the sign of the cumulative angle can also be converted into a control signal that can turn the page displayed on the screen 30 to the right or to the left. [0033] In the first embodiment, regarding the gesture control page scrolling, an object (ie, a finger) is taken as an example, and the controlled page scrolling system is a constant speed; in other words, the controller only decides The direction of the page scrolling, but does not involve the judgment of speed. However, by manipulating the increase in the number of objects, the speed of page scrolling can be further controlled. For example, the detection unit can be used to detect the number of objects, and the page scrolling speed is increased or decreased proportionally as the number of objects (for example, the number of fingers) increases or decreases. [0034] The 5D figure shows the function control of image rotation, wherein the sensing area 2040 on the right side of the sensing surface 20 is preset as an area corresponding to the function, and the object first contacts the sensing area 2040 and then slides out a two-dimensional image. The trajectory; when the accumulated value represented by the two-dimensional trajectory exceeds a threshold, the positive and negative signs of the cumulative angle are respectively converted into control signals for rotating the image on the screen 30 clockwise or counterclockwise. [0035] FIG. 5E is a functional operation for displaying image enlargement/reduction, wherein the sensing area 2042 below the sensing surface 20 is preset to correspond to the function, and the object first contacts the sensing area 2040 and then slides out. A two-dimensional trajectory; when the cumulative value exhibited by the two-dimensional trajectory exceeds a threshold, the converted non-linear index is respectively a control that can enlarge or reduce the image on the screen 30. 099119596 Form No. A0101 Page 10 of 30 Page 0992034670-0 201145097 [0036] ❹ [0039] Signal. Regarding the image rotation and the manipulation of the image enlargement/reduction function, the control signal can be further defined by the cumulative value of the cumulative angle, in addition to the above-mentioned preset threshold to determine the type of control signal represented by the non-linear index. For example, 'in terms of image rotation, in addition to clockwise or counterclockwise rotation of the image with a clockwise and inverse clock gesture', the angle of rotation of a certain direction can be further determined according to the cumulative value of the cumulative angle (for example, 90, 180, 270 degrees). Wait) . In addition, in terms of the image enlargement and reduction function, the magnification of the image enlargement or reduction can also be determined according to the integrated value of the cumulative angle.

The smth processing unit 222 is configured to sequentially process the two-dimensional trajectory obtained by the capturing unit 220 into a plurality of displacement units; then, through the foregoing comparing unit 223, the displacement amount of each displacement unit is compared with a reference. The values are compared. When the displacement amount of one displacement unit is greater than the reference value, the calculating unit 224 calculates the angle formed by the (four) direction of the purely moving unit and the displacement direction of the previous sequential displacement unit, and accumulates the aforementioned angle to obtain a cumulative angle. In addition, when the number of objects used to manipulate the touch device exceeds one, the capture criterion of the one-dimensional track may be preset, that is, the track generated by capturing some of the plurality of objects may be selected; When implemented, it is explained in the following four examples. 099119596 Form No. 1010101 Page 11 of 30 0992034670-0 201145097 [0040] The first method is to capture the two-dimensional trajectory generated by the centroid position or the geographical center position of the complex object as the displacement criterion to obtain the phase. Corresponding non-linear indicators. In other words, the first displacement of each group is between two time points, the difference of the central position of the plurality of objects contacting the sensing surface; the second displacement of each group is between the other two time points, and the plurality of objects contacting the sensing surface The difference in the center position; wherein the time point of the second displacement is later than the time point of the first displacement. Taking Figure 7A as an example, the user touches with three fingers, but the two-dimensional trajectory captured is generated by the center finger. [0041] The second way is to capture the two-dimensional representation produced by the left edge position of the plurality of objects as the displacement criterion. In other words, the first displacement of each group is between two time points, the difference between the position of the left edge of the plurality of objects contacting the sensing surface; the second displacement of each group is between the other two time points, the plurality of objects contacting the The difference in the position of the left edge of the sensing surface; wherein the time point of the second displacement is later than the time point of the first displacement. Taking Figure 7B as an example, the two-dimensional trajectory captured is generated by the left-hand finger. [0042] The third way is to capture the two-dimensional representation produced by the right edge position of the plurality of objects as the displacement criterion. In other words, the first displacement of each group is between two time points, the difference between the position of the right edge of the plurality of objects contacting the sensing surface; the second displacement of each group is between the other two time points, the plurality of objects contacting the The difference in the position of the right edge of the sensing surface; wherein the time point of the second displacement is later than the time point of the first displacement. Taking Figure 7C as an example, the two-dimensional trajectory captured is generated by the right-hand finger. [0043] The fourth way is to respectively capture the two-dimensional trajectory generated by each object, and process it into the first displacement and the second displacement of the complex array, and calculate the cumulative angle 099119596 Form No. A0101 Page 12 of 30 Page 0992034670-0 201145097 [0044] [0047] [0047]
