Abstract

A touch control method used for an electronic device storing a relationship table recording a mapping relationship between handwritten touch input and a number of commands includes the following steps. Display an electronic file. Sense a touch trace of a user on the displayed electronic file and generating a trigger signal if the touch trace forms a closed loop having an enclosed region. Sense handwritten touch input by the user within the enclosed region and generate associated signals. Recognize a circled path having an enclosed region as input by the user according to the generated signals. Determine a command associated with the sensed handwritten touch input according to the relationship table in response to the trigger signal. Retrieve content of the displayed electronic file displayed within the enclosed region. And execute the retrieved command to the retrieved content. An electronic device using the method is also provided.

Claims

1. An electronic device comprising:

a storage unit, configured for storing a relationship table recording a mapping relationship between handwritten touch inputs and a plurality of commands associated with the handwritten touch inputs;

a display unit for displaying an electronic file;

a touch input unit, configured for generating a trigger signal if a touch trace of a user on the displayed electronic file forming a closed loop having an enclosed region, sensing handwritten touch input by the user within the enclosed region and generating signals associated with the handwritten touch input; and

a processor, comprising;

a command identification module, configured for determining a command associated with the sensed handwritten touch input according to the relationship table in response to the trigger signal;

a content retrieving module, configured for retrieving content of the displayed electronic file within the enclosed region; and

a control module, configured for controlling executing the retrieved command to the retrieved content.

2. The electronic device as described in claim 1, wherein when the handwritten touch input within the enclosed region is a predetermined term or letter meaning or representative of print, the command identification module retrieves a printing command from the relationship table, and the control module controls transmitting the retrieved content to a printer for printing.

3. The electronic device as described in claim 1, wherein when the handwritten touch input within the enclosed region is a predetermined term or letter meaning or representative of fax, the command identification module retrieves a fax command from the relationship table, and the control module controls transmitting the retrieved content to a fax machine selected by the user.

4. The electronic device as described in claim 1, wherein when the handwritten touch input within the enclosed region is a predetermined term or letter meaning or representative of delete, the command identification module retrieves a deleting command associated with the touch input from the relationship table, and the control module controls deleting the retrieved content of the displayed electronic file.

5. The electronic device as described in claim 1, wherein when the handwritten touch input within the enclosed region is a predetermined term or letter meaning or representative of copy, the command identification module retrieves a copy command associated with the touch input from the relationship table, and the control module controls copying and storing the retrieved content for future use.

6. The electronic device as described in claim 1, wherein when the handwritten touch input within the enclosed region is a predetermined term or letter meaning or representative of translate, the command identification module retrieves a translation command associated with the touch input from the relationship table, and the control module controls translating the retrieved content of the displayed electronic file to a language selected by the user.

7. The electronic device as described in claim 1, wherein the handwritten touch input is selected from the group consisting of:

a character, a letter, a term, a phrase, a sentence, a symbol, a numeral, and a sign.

8. A touch control method used for an electronic device, the electronic device storing a relationship table recording a mapping relationship between handwritten touch input and a plurality of commands associated therewith, the method comprising:

displaying an electronic file;

sensing a touch trace of a user on the displayed electronic file and generating a trigger signal if the touch trace forms a closed loop having an enclosed region;

sensing handwritten touch input by the user within the enclosed region and generating signals associated with the user'"'"'s handwritten touch input;

recognizing a circled path having an enclosed region as input by the user according to the generated signals;

determining a command associated with the sensed handwritten touch input according to the relationship table in response to the trigger signal;

retrieving content of the displayed electronic file displayed within the enclosed region; and

executing the retrieved command to the retrieved content.

9. The method as described in claim 8, wherein if the handwritten touch input within the enclosed region is a predetermined term or letter meaning or representative of printing, a printing command is determined.

10. The method as described in claim 8, wherein the detail steps of “

identifying a handwritten touch input on the enclosed region input by the user according to the generated signals, and retrieving a command associated with the handwritten touch input from the relationship table” and

“

controlling executing the retrieved command to the retrieved content”

are;

identifying whether the handwritten touch input on the enclosed region input by the user is a predetermined term meaning fax;

retrieving a fax command associated with the handwritten touch input from the relationship table; and

controlling transmitting the retrieved content to a fax number selected by the user.

11. The method as described in claim 8, wherein the detail steps of “

determining a command associated with the sensed handwritten touch input according to the relationship table in response to the trigger signal” and

“

executing the retrieved command to the retrieved content”

are;

determining whether the handwritten touch input within the enclosed region is a predetermined term or letter meaning or representative of delete;

retrieving a deleting command associated with the handwritten touch input from the relationship table; and

deleting the retrieved content of the displayed electronic file.

12. The method as described in claim 8, wherein the detail steps of “

determining a command associated with the sensed handwritten touch input according to the relationship table in response to the trigger signal” and

“

executing the retrieved command to the retrieved content”

are;

determining whether the handwritten touch input within the enclosed region is a predetermined term or letter meaning or representative of copy;

retrieving a copy command associated with the handwritten touch input from the relationship table; and

copying and storing the retrieved content for future use.

13. The method as described in claim 8, wherein the detail steps of “

determining a command associated with the sensed handwritten touch input according to the relationship table in response to the trigger signal” and
