The user can touch the key ln in the virtual keyboard u to input a small word. If the user needs to input an uppercase English word, the touch-cut key device 1 needs to display the virtual D on the touch screen 14 as shown in the figure (8). The virtual keyboard 12 includes a plurality of uppercase English keys 12 and the user touches the button. 121 to lose people to write English. In order to allow the user to input a variety of characters or symbols, the virtual keyboard has one less switching key, such as the English case switching button 112 or the English button 113. Double pre-cutting However, the switching keys of this type are limited in size and are not easy to operate for users. In addition, if the number of virtual keyboards increases, for example; write keyboard, English uppercase keyboard, second language round key: number sub-keyboard, keyboard with different key layout, etc., the use of the switch key becomes complicated by 201101113, but is reduced Convenience [Summary of the Invention] In view of the above-mentioned problems of the prior art, the present invention provides an electronic device with a virtual keyboard and an i virtual = operation method to improve the convenience of switching the virtual keyboard / virtual keyboard : The purpose of L's proposed an electronic device consists of a unit 1: - unit. The processing unit is executed - the keyboard: formula is generated to > a virtual keyboard' display unit displays the virtual keyboard. The touch 7G generates a plurality of input pressing signals, and the _trajectory formed by processing a single t number of signals = at least one switch operation is performed on at least one of the keys. Paper, the switching operation can be - keyboard hidden / appearing operation, or 3 multiple virtual keyboards, or = keyboard arrangement position or (four) order. U α plural virtual virtual two virtual keyboards can include a symbol input virtual keyboard and a text input virtual keyboard. Among them, the key layout of a plurality of virtual keyboards is different. According to still another object of the present invention, a virtual keyboard method is provided for displaying an electronic device of at least one virtual keyboard, and the following steps are included. First, a lookup table is provided, which records the correspondence between the two and a switching operation. Then, receiving a plurality of rounds of signals, and then identifying the corresponding track patterns formed by the plurality of input pressing signals, and then searching for a switching operation corresponding to the identified track 201101113 trace patterns in the lookup table. Finally, at least one virtual keyboard is switched in accordance with the searched switching operation. The switching operation may be a keyboard hiding/appearing operation, or a conversion operation between a plurality of virtual keyboards, or changing the arrangement position or arrangement order of the plurality of virtual keyboards. The plurality of virtual keyboards may include a symbol input virtual keyboard and a text input virtual keyboard. _ Among them, the key layout of multiple virtual keyboards is different. [Embodiment] Please refer to Fig. 2, which is a block diagram of an embodiment of an electronic device having a virtual keyboard of the present invention. In the figure, the electronic device 2 can be a portable computer, a wireless communication device, a PDA or any touch-operated electronic device. The electronic device 2 includes a processing unit 21 and a storage unit. 22. A display unit 23 and a touch Q control unit 24. The storage unit 22 storage processing unit 21 can execute a job system 25, a keyboard program 26, a track determination program 28, and a lookup table 29. After the electronic device 2 is activated, the processing unit 21 reads the operating system 25 from the storage unit 22 and executes it to generate a user interface that allows the user to operate the basic functions of the electronic device 2 through the user interface. When the user activates the data entry function, the processing unit 21 executes the keyboard program 26 to generate at least one virtual keyboard 27. If the virtual keyboard 27 is plural, the plurality of virtual keyboards 27 preferably include virtual keyboards of different languages, or include a symbol input keyboard and a text input keyboard, or a button layout having a different 201101113. There is a pre-arranged order between the virtual keys & 27 for the user to switch, such as the first set of 97X6 ▲ brother 3 map is not 'capital English key catch order * t warehouse from stone through, number to symbol keyboard 273 — far The non-qwerty keyboard 274 is set on the top and the phonetic keyboard 275 is set on the bottom. When the touch is detected, the touch unit 24 generates an input press signal 241 including the touch position=, and transmits it to the processing unit 321%. The processing unit 21 continuously receives the plurality of input press signals 241, and includes When the touch position data changes with time, the processing unit executes a trajectory determination program 28 to identify which track pattern 211 formed by the plurality of input press signals is a trajectory pattern. The query records the correspondence between at least one track pattern and at least one switching operation as shown. Track pattern switching operation ___ Rightward track switch to right keyboard _ & Left track jump - Switch to left keyboard Switch to upper keyboard Downward switch to lower keyboard track~~——. Hide keyboard circle track L —--- Set the keyboard configuration 201101113 Apricot 4 ΓΓ 21 According to the determined trajectory pattern in the query table 29, the trajectory pattern table judged by the record in the right look-up table 29 should: switch operation to perform a virtual keyboard 27 The technique of 'track trajectory in the second operation of switching operation is no longer repeated here. The technique of W material (4) is well known, and it is a schematic diagram of the following several switching operations in Fig. 4 to Fig. 6'. In Figure 4, use the == disk: English keyboard 271 to switch to the uppercase English keyboard 272. In the future, you must find the appropriate switch button and then press the switch button, but on the second f + device 2, the user only needs to touch The touch unit is Μ 划 = track 291. When the user draws the trajectory 291, the touch unit 24 continuously generates a plurality of input pressing signals 241, and the trajectory determining program uses: ==, the input pressing signal 241 forms a rightward trajectory pattern, and the trace map: It is checked whether there is a record in the lookup table 29: the switching action corresponding to the track pattern. In the table, the record to the right is corresponding to the "switch to the right keyboard", and then corresponds to the keyboard configuration shown in Figure 3, so the processing unit 21 displays the English uppercase keyboard/2 for the user to capitalize English; similarly, if the user draws a rightward track pattern when displaying the numeric symbol keyboard 273, the processing unit 21 displays the English lowercase keyboard 271 instead. As shown in FIG. 5, the trajectory judging program 28 recognizes that the 292 formed by the input pressing signals 241 is a leftward trajectory pattern, according to the lookup table 29 (for example - for example) and f3 The keyboard configuration party processing unit 21 displays the numeric symbol keyboard 273 for the user to input numbers or symbols; similarly, if the user draws the leftward trace pattern when displaying the English uppercase write keyboard 272 7 201101113, the processing unit 21 displays the English display. Lowercase keyboard 27 In addition, when displaying the English lowercase keyboard 27 English uppercase writing keyboard 272 or the number, number keyboard 273, when the user draws an upward trajectory pattern, the processing unit 21 displays the non-qwerty keyboard 274; when the user draws out - When the track pattern is downward, the processing material 21 is changed to display the phonetic keyboard 275 °, wherein the above-mentioned track is preferably located in the display area of the virtual keyboard, so that the touch application of other non-virtual keyboards can be distinguished. In addition to switching between keyboards, the switching operation recorded in the lookup table 29 can also be a keyboard hiding/appearing operation. As shown in Fig. 6, the program 28 recognizes that the input press signal M1 forms the tick track of the keyboard. Therefore, the processing unit 21 hides the virtual b. The right plurality of virtual keyboards may include at least one single = disk mounted virtual keyboard and virtual as needed. The keyboard system can be displayed on the display at the same time. It can also be used to define special function keys or shortcut keys. The pattern of the obedience is also - the P-hidden/out of the virtual keyboard of the person has two inquiries, and the current one. Staying, as shown in Figure 7, when the execution is judged, the road Ge Ling Shang J out of the trace 294 traces The pattern, because _ 294 is - above the upper left arrow, for the HZ single; ^ the secondary keyboard 279 is displayed on the virtual keyboard unit Sia. When the right user draws the trajectory 294 again, the secondary keyboard 279 is hidden. The switch operation of the disk configuration type of the towel type record may include a key change keyboard configuration mode. In addition, the switching of the records recorded in the query table 8 201101113 may include a switching operation of the input prediction mode as needed. If the processing unit 21 has a plurality of input prediction modes, the user can also switch the input prediction mode by tiling. The virtual keyboard is displayed on the display unit 23, and in the illustration of the above embodiment, the display unit 23 is configured as a screen, and the touch unit 24 is disposed on the display unit 23. The virtual keyboard is not limited to the screen display, and the display unit 23 can also be implemented by the projection device. The virtual keyboard is projected on the touch unit 24, so that the user can recognize the key position of the virtual key disk for operation. Please refer to FIG. 8 , which is a flow chart showing the steps of the virtual keyboard operating method of the present invention. In the figure, the method is for an electronic device capable of displaying at least one virtual keyboard, which comprises the following steps. In step 81, a lookup table is provided, which records the correspondence between a track pattern and a switching operation, as shown in Table 1. A plurality of input press signals are then received at step 82. Wherein, if the virtual keyboard is plural, it preferably includes a virtual keyboard of different language systems, or a symbol input keyboard and a text input keyboard, 〇 or a different key layout (qwerty keyboard and non-qwerty keyboard). In step 83, a track pattern corresponding to a track formed by a plurality of input press signals is identified. Preferably, the trajectory is located in a display area of the virtual keyboard. In step 84, the lookup table is searched for a switching operation corresponding to the identified trace pattern. At step 85, at least one virtual keyboard is switched in accordance with the searched switching operation. If there is only one virtual keyboard, the switching operation can be the hidden/appearing operation of the keyboard, or the input prediction mode of 201101113. If the two keys are used: the above two switching operations can be virtual = hidden, now 'or 4 ==Disc: Arrange the position or order. From Taigong is an example, (4) is limited.
