Description of the Invention: [Technical Field] The present invention relates to a data selection method and system, and more particularly to a method for selecting a character symbol through a touch display unit and adjusting a range of selected character symbols Method and system. [Prior Art] In recent years, portable devices, particularly hand-held devices, have become more advanced and more functional. For example, handheld devices can have telecommunications capabilities, e-mail, advanced address book management, media playback, and a host of other capabilities and applications. Due to the convenience of these devices, these devices have also become one of the necessities of life. Currently, many handheld devices are equipped with touch-sensitive display units. Users can directly perform related operations, such as operating applications and data input, through the touch display unit. In some cases, the user often wants to select and copy a piece of text displayed in the touch-sensitive display unit, and then paste the text into another application. However, due to the size limitation of the touch display unit and the displayed text, if the user selects the text using the finger, the cursor and the text are often blocked by the finger, which may result in the inability to accurately select a piece of text, which causes operational troubles. On the other hand, when the text is selected incorrectly, the user must repeatedly select the text, and each time the text is re-selected, the previously selected text will be canceled, causing inconvenience to the user. In addition, the user can also press a specific button, such as the CTRL button, and simultaneously select to complete the adjustment of the selected text. At the same time, pressing a specific button and performing text selection in a hand-held HTC098026/0746-A42027-TW/Draft-Final/ 4 201112040 device with a limited area is very difficult and inconvenient to operate. SUMMARY OF THE INVENTION In view of this, the present invention provides a data selection method and system. A data selection method according to an embodiment of the present invention. First, the data including the complex digital symbol is displayed in a touch display unit, and the selection of at least one of the corresponding character symbols is received through the touch display unit. Then, detecting one of the corresponding selected character symbols on the touch display unit, and determining a specific boundary of the selected character symbol according to the position corresponding to the selected character symbol. Wherein, when the contact is within a predetermined range of the first boundary of one of the selected character symbols, the specific boundary is determined to be the first boundary. Thereafter, one of the touch display units is detected to move, and the range of the selected character symbols is adjusted according to the movement and the specific boundary. A data selection system according to an embodiment of the invention includes a touch display unit and a processing unit. The touch display unit displays data including complex digital symbols. The processing unit receives the selection of at least one of the corresponding character symbols by the touch display unit. The processing unit detects one of the corresponding selected character symbols on the touch-sensitive display unit, and determines a specific boundary of the selected character symbol according to the position corresponding to the selected character symbol. Wherein, when the contact is within a predetermined range of the first boundary of one of the selected character symbols, the specific boundary is determined to be the first boundary. The processing unit detects a movement on the touch display unit and adjusts the range of the selected character symbol according to the movement and the specific boundary. In some embodiments, after detecting the movement on the touch-sensitive display unit, a predetermined time may be delayed, and after a predetermined time, the range of the selected character symbol is adjusted according to the movement and the specific boundary. HTC098026/0746-A42027-TW/Draft-Final/ 5 201112040 ;^Invented the above method can exist through code. When the code is carried by the machine and executed, the machine becomes the device for carrying out the invention. The above described objects, features and advantages of the present invention will become more apparent from the description of the appended claims. [Embodiment] FIG. 1 shows a data selection system according to an embodiment of the present invention. The data selection system 100 according to the embodiment of the present invention can be applied to an electronic device such as a portable device such as a personal digital assistant, a smart phone, a mobile phone, a mobile Internet device (MID), or a mini-note type. Handheld devices such as computers (Netbooks). The data selection system 1 includes at least one touch display unit 110, a storage unit 120, and a processing unit 130. The touch display unit 110 is coupled to a screen of a touch sensing device (not shown). The touch sensing device has a touch surface including at least one dimensional sensor for detecting contact and movement of an input tool such as a finger or a stylus on its surface. The touch display unit 110 can display related materials, and/or related icons and interfaces, and the like. The storage unit 12A may include information provided to the touch display unit for display. Where t, the data may include complex digital meta-symbols. The processing unit 130 is configured to perform the data selection method of the present case, the details of which will be described later. Figure 2 shows a method of selecting data in accordance with an embodiment of the present invention. The data selection method according to the embodiment of the present invention can be applied to an electronic device such as a portable device, such as a personal digital assistant, a smart phone, a mobile phone, a mobile internet device, or a mini-note computer. In step S210, the information including the complex digital element HTC098026/0746-A42027-TW/Drafl-Final/ Λ 201112040 symbol is displayed in the touch display unit. Then, in step S220, the selection of at least one of the corresponding character symbols is received through the touch-sensitive display unit. It should be noted that in some embodiments, the selection of the corresponding character symbol can be accomplished by double clicking on the character symbol through the touch display unit. In some embodiments, the selection of the corresponding character symbol can be accomplished by touching the touch display unit to the character symbol for a predetermined time (long press). In some embodiments, the selection of the corresponding character symbol can be accomplished by dragging the touch symbol on the character symbol. Note that the above manner of selecting a character symbol is only an example of the present case, and the present invention is not limited thereto. Additionally, in some embodiments, the selected character symbols can be highlighted in a touch sensitive display unit. Then, in step S230, one of the corresponding selected character symbols on the touch-sensitive display unit is detected to be in contact, and in step S240, a specific boundary of the selected character symbol is determined according to the position corresponding to the selected character symbol. It is worth noting that in this case, the contact does not have to be precisely pointed to the left or right boundary of the selected symbol to complete the selection of one of the boundaries. Figure 3 shows a method of determining a particular boundary in accordance with an embodiment of the present invention. • In step S310, it is determined whether the contact is within a predetermined range of the right boundary of the selected character symbol, such as within a circular range of a given radius centered on the right boundary. If the contact is within the predetermined range of the right boundary of the selected character symbol (YES in step S310), in step S320, the specific boundary is determined to be the right boundary, and the flow is ended. If the contact is not within a predetermined range of the right boundary of the selected character symbol (No in step S310), it is determined whether the contact is within a predetermined range of the left boundary of the selected character symbol, such as a circle having a predetermined radius centered on the left boundary Within the shape range. If the contact is within a predetermined range of the left boundary of the selected character symbol (YES in step S330), as in step S340, the specific boundary is determined to be. HTC098026/0746-A42027-TW/Draft-Final/ 201112040 Left boundary and end the process. If the contact is not within the predetermined range of the left boundary of the selected character symbol (NO in step S330), the flow is ended. Fig. 4 shows an example of a specific boundary decision in accordance with an embodiment of the present invention. As shown in Fig. 4, the range of the selected character symbol ST has a right boundary RB and a left boundary LB. When the contact position of the user's finger is located in the predetermined range RPR of the right border RB, the specific boundary is determined as the right boundary RB. When the contact position of the user's finger is in the predetermined range LPR of the left border LB, the specific boundary is the left boundary LB. After the specific boundary is determined, the reference to FIG. 2 is continued. In step S250, one of the touch display units is detected to move. If no movement is detected on the touch-sensitive display unit (NO in step S250), the determination in step S250 is continued. If the movement is detected on the touch-sensitive display unit (YES in step S250), in step S260, the range of the selected character symbol is adjusted according to the movement (including direction and distance) and the specific boundary. For example, when a particular boundary is a right border and the direction of movement is to the right, the right border of the selected character symbol will be adjusted to the right to select more character symbols. The reminder is that unlike the conventional technique of re-selecting text, the previously selected text will be canceled. In this case, not only does it need to press extra keys, but after the specific boundary is decided, the previously selected character symbol will continue. Reserved for subsequent adjustments to increase user convenience. Figure 5 shows a data selection method in accordance with another embodiment of the present invention. The data selection method according to the embodiment of the present invention can be applied to an electronic device such as a portable device such as a personal digital assistant, a smart phone, a mobile phone, a mobile internet device, or a mini-note computer. HTC098026/0746-A42027-TW/Draft-Finay 8 201112040 In this embodiment, the adjustment of the selected character symbol range and the movement of the finger can have a time difference to increase the convenience of the user to view the selected character symbol. In step S510, the data including the complex digital symbol is displayed in the touch display unit. Then, in step S520, the selection of at least one of the corresponding character symbols is received through the touch display unit. Similarly, the selection of the corresponding character symbol can be performed by double-clicking on the character symbol through the touch-sensitive display unit, touching the character symbol on the character symbol for a predetermined time (long press), and/or The touch display unit is dragged on the character symbol to complete. Similarly, in some embodiments, the selected character symbols can be highlighted in a touch-sensitive display unit. Then, in step S530, one of the corresponding selected character symbols on the touch-sensitive display unit is detected to be in contact, and in step S540, a specific boundary of the selected character symbol is determined according to the position corresponding to the selected character symbol. It is noted that the method of determining a particular boundary may be similar to the embodiment of Figure 3, the details of which are omitted herein. After the specific boundary is determined, in step S550, one of the touch display units is detected to move. If no movement is detected on the touch display unit (NO in step S550), the determination in step S550 is continued. If the movement is detected on the touch display unit (YES in step S550), in step S560, the delay is for a predetermined time, such as 0.5 or 1 second, and after a predetermined time, as in step S570, according to the movement (including direction and distance). ) Adjust the range of selected character symbols with a specific boundary. 6A to 6C are diagrams showing an example of adjustment of the range of selected character symbols in accordance with an embodiment of the present invention. First, the user touches the vicinity of the right border RB of the range of the corresponding selected character symbol ST on the touch display unit by using the finger F, thereby determining that the specific boundary is the right border RB, as shown in FIG. 6A & HTC098026/0746-A42027- TW/Draft-Final/ 9 201112040 shown. After that, use the finger F to move to the right and the winter finger F to move to the right as shown in Fig. 0B.
