Abstract

The disclosure provides a method for collaboratively operating shared content in a video conference, wherein the shared content is shared by a sharing terminal to a shared terminal. In the method, an operation event is transmitted by the shared terminal to the sharing terminal. The operation event is then transmitted to a virtual device of the sharing terminal, and the operation event is performed on the shared content by the virtual device.

Claims

1. A method for collaboratively operating shared content in a video conference, wherein the shared content is shared by a sharing terminal to a shared terminal, the method comprising:

transmitting an operation event by the shared terminal to the sharing terminal;

transmitting the operation event to a virtual device of the sharing terminal; and

performing the operation event on the shared content by the virtual device.

2. The method as claimed in claim 1, further comprising:

setting the shared content to be able to be operated collaboratively by the sharing terminal.

3. The method as claimed in claim 2, further comprising:

determining whether the shared content is able to be operated collaboratively and, if so, transmitting the operation event to the virtual device of the sharing terminal.

4. The method as claimed in claim 3, further comprising:

determining whether the operation event is performed within an active region of the shared content according to coordinates of the operation event in the shared terminal and, if so, transmitting the operation event by the shared terminal to the sharing terminal.

5. The method as claimed in claim 4, further comprising:

normalizing the coordinates and generating normalized coordinates for the operation event; and

determining performing coordinates, which are used when the operation event is performed on the shared content, according to the normalized coordinates, and directing the virtual device to perform the operation event on the shared content according to the performing coordinates.

6. A video conferencing system, including a sharing terminal and a shared terminal, wherein the sharing terminal and the shared terminal are connected to each other through a network, wherein the sharing terminal comprises:

a sharing unit, sharing shared content to the shared terminal through the network;

a process unit, receiving an operation event from the shared terminal through the network; and

a virtual device system, receiving the operation event from the process unit and assigning the operation event to a virtual device which performs the operation event on the shared content, and

wherein the shared terminal comprises;

a shared unit, receiving the shared content through the network and displaying the shared content on a display unit of the shared terminal; and

a detect/retrieve unit, detecting the operation event, retrieving the operation event, and transmitting the operation event to the process unit through the network.

7. The video conferencing system as claimed in claim 6, wherein the process unit further determines whether the shared content is able to be operated collaboratively and, if so, transmits the operation event to the virtual device of the virtual device system.

8. The video conferencing system as claimed in claim 7, wherein the detect/retrieve unit further determines whether the operation event is performed within an active region of the shared content according to coordinates of the operation event relative to the shared content and, if so, transmits the operation event to the process unit through the network.

9. The video conferencing system as claimed in claim 8, wherein the detect/retrieve unit further normalizes the coordinates and generates normalized coordinates for the operation event, and the process unit further determines performing coordinates, which are used when the operation event is performed on the shared content, according to the normalized coordinates, and the virtual device performs the operation event on the shared content according to the performing coordinates.

10. A computer program embodied in a non-transitory computer-readable storage medium, wherein the computer program is loaded into and executed by an electronic device for collaboratively operating shared content in a video conference, the computer program comprising:

a first code for setting shared content, which is shared by a sharing terminal to a shared terminal, to be able to be operated collaboratively;

a second code for directing the shared terminal to determine whether the operation event is performed within an active region of the shared content according to coordinates of the operation event in the shared terminal and, if so, directing the shared terminal to normalize the coordinates to generate normalized coordinates and transmit the operation event to the sharing terminal;

a third code for directing the sharing terminal to determine whether the shared content is able to be operated collaboratively and, if so, directing the sharing terminal to determine performing coordinates, which are used when the operation event is performed on the shared content according to the normalized coordinates, and transmit the operation event to a virtual device of the sharing terminal; and

a fourth code for directing the virtual device to perform the operation on the shared content according to the performing coordinates.
