For example, handheld devices can have telecommunications capabilities, email, 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 a touch display unit. 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, thereby causing a situation in which a piece of text cannot be accurately selected, 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, thereby 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 handheld device having a limited area is very difficult and inconvenient in operation.

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 100 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 120 may include information provided to the touch display unit 110 for display. Among them, the data may include complex digital 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 handheld device such as a mini notebook computer.

In step S210, the data including the complex digital 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 display unit. It should be noted that in some embodiments, the selection of the corresponding character symbol may be performed 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 contacting the touch display unit with 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. It should be noted that the above manner of selecting a character symbol is merely an example of the present case, and the present invention is not limited thereto. In addition, in some embodiments, the selected character symbols can be highlighted in the touch 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 character 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 predetermined 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 the predetermined range of the left boundary of the selected character symbol (YES in step S330), in step S340, the specific boundary is determined to be the left boundary, and the flow is ended. 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. Figure 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 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 boundary LB, the specific boundary is determined as 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 display unit (NO in step S250), the determination in step S250 is continued. If the movement is detected on the touch 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 specific boundary is a right boundary and the moving direction is rightward, the right boundary 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 handheld device such as a mini notebook computer. In this embodiment, the adjustment of the selected character symbol range and the movement of the finger may 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, contacting the character symbol on the character symbol for a predetermined time (long press), and/or through the touch. The controlled 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, delay 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. After that, the user moves the finger F to the right as shown in FIG. 6B.
