Description of the Invention: [Technical Field of the Invention] The present invention relates to a method for operating an object on a touch screen. The method of making, especially with multiple fingers [previous technique] A large part of the conventional touchpad or the use of an object, such as - the root finger = the touch screen of the control screen is the control panel or the familiar touch Control the screen to do the ^ stylus 'in the touch. This type of conventional touchpad is either a known touchpad or a positional shop that can't be used for multiple objects (such as multiple fingers). The gesture commands developed by the conventional touch screen have to be limited. In the Taiwan Invention Patent Application No. _18951 "Multiple Object Detection Method for Capacitive Touch Panel", it has been revealed that a multi-object debt measurement method for a capacitive touch panel is provided by at least - preset_ It is the interference of the noise or the object on the touchpad relies on 'touching or leaving the touchpad with the correct touch object, so as to accurately detect the operation of various gestures. The disclosed Capacitor 2 touchpad provides positional measurement of multiple objects. The inventors of the present invention have in view of the conventional method of operating an object on a touch screen, that is, the gesture 'has still improved, and thus the invention is improved and improved. The method for operating an object with a plurality of fingers on a touch screen . 200925952 [Summary of the Invention]. The touch of a borrower's eve finger on the touch screen becomes a touch-touch object. This towel's so-called main operation package 3 selects an object, moves an object, enlarges an object, and reduces an object. In order to achieve the above object of the present invention, the present invention provides a method for operating a plurality of fingers == on-screen operation object, including: the first step is to obtain the position information of the touched point; the second step is to If the touched point is greater than or equal to three', it is judged whether the area composed of the plurality of touched inspection information contains the object, and the third step takes the area in the second step_the object. Then, in the other touches of the touch screen, the selected object is shifted, enlarged/reduced, and the like. The invention of the present invention is further understood by the following description of the invention. [Embodiment] The first figure is a schematic diagram of the operation of the method for operating an object on the touch screen. The touch screen 1 is used in the method of operating the object of the present invention to directly use the conventional touch screen. In general, the touchwire includes a touch panel 10 and a display 12 that can display objects 14a, 14b. Since the touch panel 10 is a transparent body, when the touch panel 10 is overlaid on the display 12, the objects 14a, 14b are observed at the mouth. Touch screen i can _ to multiple fingers press ^ 200925952 f control board 10 on the position information of a plurality of touched traces F3, such as = the user's three fingers pressed on the touchpad iq touched Touch it. The position information of the touch (4) screen 1 can be taken as a field mark or a relative coordinate. For example, the coordinates of the touched point F1 are _), and so on. The coordinates of the touched points F1 to F3 are touched by the main _ to select whether the object displayed on the display η is selected, and the object referred to here, for example, the program shortcut pattern (iGQn) displayed on the desktop of the window operating system. . In different applications, the piece may also be a picture to be processed, for example, in an image processing program. The second heart F image is a schematic diagram of the method for operating an object by using a plurality of fingers on the touch screen. The second A figure gesture on the touch screen can be used as the object selection command of the present invention. As shown in the second figure A, the gamma uses three fingers to touch the touch screen i near the same time, so that the touch screen senses two touch points F2 and F3. If there is an image object 14a in the area formed by the touch point n, F2 and F3, the host selects the image object (4). The touch screen 1 detects and analyzes the position information of the plurality of touched points F1~F3 touched by the touch finger surface, and then the touch screen jade will correspond to the touched touches. The coordinates f of the points F1 to F3 are transmitted to the host. The host calculates the area formed by the touched points F1 to F3 based on the coordinates of the touch points F1 to F3. Next, the host determines whether the area contains an object, e.g., the image object 14a is included in the area, and the image object 14a is selected. 200925952 According to the present invention, the touched object of the _ control and the screen must be greater than or equal to three, because three points can constitute one face - more than one touch point F F3 gets a virtual area. Of course, 'this method of financing is not only _ can only be operated through three touched points'. The invention can also be operated with more than three touched points, as the third figure does not 'completely four fingers Perform an action like selecting an object. Moreover, the touch screen of the touch screen with the method of the crop material has good index sensing capability. The bottom mosquito will use the __ Benfa duck as the other embodiment of the method. ° °F, see the second B picture, in the position information of the plurality of touched points F1~F3, the maximum and minimum coordinate values of the X-axis are obtained in the X-axis to obtain the maximum inter-axis and the leaf in the Y-axis. Maximum and minimum coordinate values to obtain the maximum distance of the γ axis. For example, in a plurality of touched points F1 to F3, the maximum and minimum coordinate values in the γ-axis are Y3 and γ, respectively, and the maximum and minimum values of the 裇 in the χ axis are Χ3 and xi, respectively, so γ The maximum distance of the axis is the distance from γ3 to γι, and the maximum spacing of the X axis is the distance from X3 to X1. Therefore, in the method for fabricating the object of the present invention, by using the coordinates of the touched points F1 to F3, the maximum pitch of the X-axis and the maximum pitch of the Y-axis, a virtual rectangular region 16a' is obtained by calculation and the virtual rectangular region is obtained. The four endpoint coordinates of 16a are (χι,Η), «1,Υ3), (Χ3,Υ1), (χ3,Υ3). That is, the electronic machine implementing the method of the present invention determines a virtual 200925952 rectangular area 16a based on the coordinates of the plurality of touched points F1 to F3. Next, it is judged whether or not the virtual rectangular area 16a contains an object, for example, the image object 14a is included in the virtual rectangular area 16a, and the image object 14a', that is, the image object i4a is selected as the selected object. The electronic device determines, according to the four endpoint coordinates of the virtual rectangular area 16a, which coordinates of all the image objects are located in the range of the virtual rectangular area 16a. For example, the image object 14a is determined to be selected by the electronic device. object. The above-mentioned means for calculating the virtual rectangular area 16a is only used to explain how to form an area in the fine touch points F1 to F3. However, the present invention is not limited thereto. According to an embodiment of the invention, if the movement of the touched point area is detected, then the selected object is moved. Referring to the second c-figure, when the coordinates of the touched points F1 to F3 are changed to the new position information (that is, the touched point 1 F3 ) % ', the selected image object 14a is correspondingly Move to the new location location. In other words, the movement of the second c-off gesture can be used as the image object shift command of the present invention. In the second C picture, in the process of moving the image object 14a in the virtual rectangular area 16a to the virtual rectangular area 16b, the user's three fingers are mailed on the touch screen 1 to make up the control. Point 3, Pitogo (4) coordinates are side and analyze the sister, it is possible to determine the direction and displacement of the touch point movement, and accordingly move the object 14a. 200925952 The operation of the gesture of dragging the surface of the object is as follows: If _ is touched and F3 has one or more touch points on the touch screen! Moving 'the cow case', the individual touches the finger of the touched Wei F3 touched by the touch wire, and only the two fingers hit by the touch point (four) move on the touch screen 1 'the corresponding The thief moves the selected object 14a until the towed touch points FI, F2 stop dragging. In the second D picture, 'when the user completes the selection operation of selecting the image object...', then, the langer only has _ two fingers, that is, the touch point Η and F2, and the thief Wei on the touch screen , drag _ action until the touch point FI F2 stops. The coordinates of the touched points F1 and F2 on the touch screen 1 will be made and difficult, and the coordinates generated when the upper touch points ρι, F2 are dragged (four) will be processed and parsed. . Finally, the last dragged position on the touch screen will be side-by-side and parsed, that is, touched off, F2. According to the side touch point HX and the seat when it is dragged, the displacement direction of the touched points FI and F2 can be changed, and the displacement direction is changed, and the virtual rectangular area is selected as the selected image. The object 14a follows the direction of the displacement, and moves and drags the selected image object 14a. Please refer to the second E, F image. If one or more of the touched points π to F3 are detected, one or more touches are detected. The point changes to the new position, and the change of the 200925952 touch of the gesture causes the area formed by the three touched points to change, and the corresponding change changes the size of the selected object. This Wei can be processed, for example, in an image. In the second E diagram, in the process in which the image object (4) in the virtual rectangular area 16a is enlarged to the relative position of the virtual rectangular area 16b, the user will be dragged outward by the touch point 座 (coordinate (χι, Υ 1)). To the touched point η, (coordinate (XI, Π,)). In the touch screen 1, from the touched point F1 (coordinates (χι, γι) dragged to the touched point F1, (shop 1 ,, γι,)) The coordinates of the change are detected and resolved. According to the touch points F1 to F3, and the calculation, the virtual moment domain 16a, the hall, and the area change of the virtual rectangular area 16a and the virtual rectangular area 16b are calculated. Because the changed virtual rectangle The area of the area 16b is larger than the virtual rectangular area 16a before the change, and therefore, the image object 14a in the virtual rectangular area is enlarged to the relative position of the virtual rectangular area 16b according to the magnification ratio of the area change. In the third F picture, in the process in which the image object 14a in the virtual rectangular area 16a is reduced to the relative position of the virtual rectangular area, the user drags the touched point F1 (coordinate (X1, Y1)) inwardly to Touched point F1 (seat (XI, Y1)). In the touch screen, drag from the touched point (coordinate (X1, Y1)) until it is touched by F1' (coordinate (χι,, γι) , "All the coordinates of the change" will be measured and analyzed. According to the touch points F1~F3, F1', the virtual rectangular areas 16a, 16b are respectively obtained, and then 11 200925952, the virtual rectangular area 16b is calculated. The ratio of the area to the virtual __shirt is changed. Because The secret virtual rectangle area 16b is less than the virtual rectangular area 16a before the change. Therefore, the image object 14 in the virtual rectangular area 16a is reduced to the relative position of the virtual rectangular area 16b according to the reduction ratio of the area change ratio. According to the characteristics of the touch screen 1, the user can also touch the touch screen 1 with four fingers or five fingers. In the third towel, #四 finger touches the touch panel 1G At the time of 'touching the screen 丨 _ and analyzing the position information of the touched point called 4 ,, according to the coordinates of the touched points F1 to F4, the area formed by the touched points F and F4 can be obtained. For example, the virtual rectangular area is obtained according to the above calculation principle of the maximum spacing of the X-axis and the maximum spacing of the Y-axis. As for how to advance the selection, (4), enlarge and reduce the potential action, it is no longer described. The method for operating an object on a touch screen by using a plurality of fingers can be implemented by means of firmware or software, for example, by using a touch screen controller to obtain coordinates and lying gestures, or * fine control screen belongs to The software installed on the host determines the gesture and further determines the function corresponding to the gesture. The present invention can be applied to a personal assistant (PDA), a notebook computer, a mobile phone, a portable multimedia player, a portable game machine, and the like. The features and spirits of the present invention are intended to be more apparent from the detailed description of the preferred embodiments described herein.
