Abstract

Data selection and display methods and systems are provided. First, data including a plurality of characters/symbols is displayed in a touch-sensitive display unit. A contact corresponding to an input tool on the touch-sensitive display unit is detected. According to the contact position on the touch-sensitive display unit, a plurality of candidate characters/symbols is determined from the characters/symbols, and a specific position where the candidate characters/symbols to be displayed in the touch-sensitive display unit is re-determined. Then, the candidate characters/symbols are displayed at the specific position in the touch-sensitive display unit.

Claims

1. A data selection and display method for use in an electronic device, comprising:

displaying data comprising a plurality of characters/symbols in a touch-sensitive display unit;

detecting a contact corresponding to an input tool on the touch-sensitive display unit;

determining a plurality of candidate characters/symbols from the characters/symbols according to the contact position on the touch-sensitive display unit;

re-determining a specific position where the candidate characters/symbols to be displayed in the touch-sensitive display unit according to the contact position on the touch-sensitive display unit; and

displaying the candidate characters/symbols at the specific position in the touch-sensitive display unit.

2. The method of claim 1, wherein a predefined number of the characters/symbols around the contact position is determined as the candidate characters/symbols, wherein the contact position is in the center of the candidate characters/symbols.

3. The method of claim 1, wherein the contact corresponding to the input tool has a contact range, and the characters/symbols within the contact range are determined as the candidate characters/symbols.

4. The method of claim 1, wherein a row or a column of the characters/symbols located at the contact position is determined as the candidate characters/symbols.

5. The method of claim 1, wherein the specific position is determined around the contact position.

6. The method of claim 5, wherein a distance between the specific position and the contact position is a predefined length.

7. The method of claim 1, wherein the contact corresponding to the input tool has a contact range, and the specific position is located at outside of the contact range.

8. The method of claim 1, further comprising:

displaying an interface at the specific position in the touch-sensitive display unit, wherein the interface is translucent or has a specific color; and

displaying the candidate characters/symbols on the interface.

9. The method of claim 1, further comprising:

detecting a movement on the touch-sensitive display unit; and

moving the candidate characters/symbols according to the movement.

10. The method of claim 1, further comprising:

displaying a cursor within the candidate characters/symbols according to the contact position;

detecting a movement on the touch-sensitive display unit; and

moving the cursor among the candidate characters/symbols according to the movement.

11. A data selection and display system for use in an electronic device, comprising:

a touch-sensitive display unit displaying data, wherein the data comprises a plurality of characters/symbols; and

a processing unit detecting a contact corresponding to an input tool on the touch-sensitive display unit, determining a plurality of candidate characters/symbols from the characters/symbols according to the contact position on the touch-sensitive display unit, re-determining a specific position where the candidate characters/symbols to be displayed in the touch-sensitive display unit according to the contact position on the touch-sensitive display unit, and displaying the candidate characters/symbols at the specific position in the touch-sensitive display unit.

12. The system of claim 11, wherein the processing unit determines a predefined number of the characters/symbols around the contact position as the candidate characters/symbols, wherein the contact position is in the center of the candidate characters/symbols.

13. The system of claim 11, wherein the contact corresponding to the input tool has a contact range, and the processing unit determines the characters/symbols within the contact range as the candidate characters/symbols.

14. The system of claim 11, wherein the processing unit determines a row or a column of the characters/symbols located at the contact position as the candidate characters/symbols.

15. The system of claim 11, wherein the specific position is determined around the contact position.

16. The system of claim 15, wherein a distance between the specific position and the contact position is a predefined length.

17. The system of claim 11, wherein the contact corresponding to the input tool has a contact range, and the specific position is located at outside of the contact range.

18. The system of claim 11, wherein the processing unit further displays an interface at the specific position in the touch-sensitive display unit, and displays the candidate characters/symbols on the interface, wherein the interface is translucent or has a specific color.

19. The system of claim 11, wherein the processing unit further detects a movement on the touch-sensitive display unit, and moves the candidate characters/symbols according to the movement.

20. The system of claim 11, wherein the processing unit further displays a cursor within the candidate characters/symbols according to the contact position, detects a movement on the touch-sensitive display unit, and moves the cursor among the candidate characters/symbols according to the movement.

21. A machine-readable storage medium comprising a computer program, which, when executed, causes a device to perform a data selection and display method, wherein the method comprises:

displaying data comprising a plurality of characters/symbols in a touch-sensitive display unit;

detecting a contact corresponding to an input tool on the touch-sensitive display unit;

determining a plurality of candidate characters/symbols from the characters/symbols according to the contact position on the touch-sensitive display unit;

re-determining a specific position where the candidate characters/symbols to be displayed in the touch-sensitive display unit according to the contact position on the touch-sensitive display unit; and

displaying the candidate characters/symbols at the specific position in the touch-sensitive display unit.
