Abstract

Methods for data transmission for use in an electronic device including a touch-sensitive display unit are provided. First, a first event indicating that a specific button has been pressed, and then held is received. In response to the first event, contacts and movements of an object on the touch-sensitive display unit are received and touching script data corresponding to the contacts and movements of the object are recorded. Thereafter, in response to receiving a second event indicating that the specific button has been released, the touching script data is transmitted to at least one device such that the touching script data is displayed in a display unit of the device when the touching script data has been received.

Claims

1. A method for data transmission, for use in an electronic device at least comprising a touch-sensitive display unit, comprising:

receiving a first event indicating that a specific button has been pressed and then held;

in response to the first event, receiving contacts and movements of an object on the touch-sensitive display unit and recording touching script data corresponding to the contacts and movements of the object; and

in response to receiving a second event indicating that the specific button has been released, transmitting the touching script data to at least one device such that the touching script data is displayed in a display unit of the device when the touching script data has been received,

wherein visually observable data containing the touching script data displayed in the touch-sensitive display unit is not clickable by the object when the specific button has not been released and is clickable by the object when the specific button has been released, and

wherein the object is a stylus including the specific button and the first event indicating that the specific button has been pressed and held is generated by the stylus.

2. The method of claim 1, wherein the step of recording touching script data corresponding to the contacts and movements of the object further comprises:

displaying the touching script data corresponding to the contacts and movements of the object in the touch-sensitive display unit.

3. The method of claim 1, wherein the step of transmitting the touching script data to at least one device further comprises:

transmitting the touching script data to the at least one device via a wireless network or a near field communication (NFC).

4. The method of claim 1, wherein the step of transmitting the touching script data to at least one device further comprises:

transmitting the touching script data to the at least one device via a server of a network.

5. The method of claim 1, further comprising:

receiving a replied touching script data from the device; and

displaying the replied touching script data in the touch-sensitive display unit, wherein the visually observable data displayed in the touch-sensitive display unit is not clickable until the specific button has been clicked or a specific gesture has been detected.

6. An electronic device, comprising:

a storage unit;

a touch-sensitive display unit displaying visually observable data;

a transmission module; and

a processing unit receiving a first event indicating that a specific button has been pressed, and then held,

in response to the first event, receiving contacts and movements of an object on the touch-sensitive display unit and recording touching script data corresponding to the contacts and movements of the object, and

in response to receiving a second event indicating that the specific button has been released, transmitting the touching script data to at least one device via the transmission module such that the touching script data is displayed in a display unit of the device when the touching script data has been received,

wherein visually observable data containing the touching script data displayed in the touch-sensitive display unit is not clickable by the object when the specific button has not been released and is clickable by the object when the specific button has been released, and

wherein the object is a stylus including the specific button and the processing unit further receives the first event generated by the stylus.

7. The electronic device of claim 6, wherein the processing unit further displays the touching script data corresponding to the contacts and movements of the object in the touch-sensitive display unit when recording touching script data corresponding to the contacts and movements of the object.

8. The electronic device of claim 6, wherein the processing unit further transmits the touching script data to the device via the transmission module via a wireless network or a near field communication (NFC).

9. The electronic device of claim 6, wherein the processing unit further transmits the touching script data to the device via the transmission module via a server of a network.

10. An input device for handwritten data, comprising:

a stylus comprising a stylus nib and a button;

a button;

a transmission module; and

a control unit recording contacts and movements of the stylus nib in response to a first event indicating that the button has been pressed and then held, and

in response to receiving a second event indicating that the button has been released, generating touching script data corresponding to the contacts and movements of the stylus nib and transmitting the touching script data to at least one device via the transmission module such that the touching script data is displayed in a display unit of the at least one device when the touching script data has been received,

wherein visually observable data containing the touching script data displayed in the touch-sensitive display unit is not clickable by the stylus nib when the specific button has not been released and is clickable by the stylus nib when the specific button has been released.

11. The input device for handwritten data of claim 10, further comprising buttons for selecting and indicating the at least one device.

12. The input device for handwritten data of claim 10, further comprising a display unit for displaying the touching script data.

13. A non-transitory machine-readable storage medium comprising a computer program, which, when executed, causes a device to perform a method for data transmission, wherein the method comprises:

receiving a first event indicating that a specific button has been pressed and held;

in response to the first event, receiving contacts and movements of an object on a touch-sensitive display unit and recording touching script data corresponding to the contacts and movements of the object; and

in response to receiving a second event indicating that the specific button has been released, transmitting the touching script data to at least one device,

wherein visually observable data containing the touching script data displayed in the touch-sensitive display unit is not clickable by the object when the specific button has not been released and is clickable by the object when the specific button has been released, and

wherein the object is a stylus including the specific button and the processing unit further receives the first event generated by the stylus.
