Method for operating object between terminals and terminal using the method
A method for operating an object between a first terminal and a second terminal. The display space of one of the first and second terminals is extended to the other terminal. One of the first and second terminals intercepts an event associated with the object occurring in the terminal so as to obtain the position of the object, informs the other terminal of the position of the object, and redraws the object on the screen of the other terminal based on the received position.
1. A method of operating an object between a first terminal and a second terminal, wherein the first terminal and the second terminal are provided with respective input devices and displays, the method comprising:
extending the display space of the first terminal to the second terminal and the display space of the second terminal to the first terminal;
intercepting at the first terminal an event associated with a cursor occurring in the first terminal so as to obtain the position of the cursor;
informing the second terminal of the position information and movement information of the cursor and input information such that the second terminal redraws the cursor on the screen of the second terminal using the received position information when the position of the cursor indicates that the cursor needs to be displayed on the screen of the second terminal;
authorizing, by the second terminal, the control right for the redrawn cursor so that the cursor can be moved on the screen of the display of the second terminal; and
calculating, at the second terminal, the movement position of the redrawn cursor based on the movement information received from the first terminal, and controlling an object on the display of the second terminal based on the input information received from the first terminal.
2. The method of claim 1 , wherein said extending comprising mapping the coordinate system of the first terminal or the second terminal to the coordinate system of the second terminal or the first terminal in an arbitrary direction.
3. The method according to claim 1 , wherein the display modes/mode of the first terminal and/or the second terminal are/is converted so that the display modes of the first and second terminals are identical.
4. The method according to claim 1 , wherein redrawing the cursor comprises placing information on the cursor in a display memory of the second terminal or the first terminal through GDI or DIRECTX.
5. The method according to claim 1 , wherein the first and second terminals are connected by a network and transmit data over the network.
6. The method according to claim 5 , wherein said network comprises a wired network or a wireless network.
7. A system of operating an object between a first terminal and a second terminal, the first terminal, wherein the first terminal and the second terminal each is provided with an input device and a display, the first terminal comprising:
means for extending the display space of the first terminal to the second terminal;
means for intercepting at the first terminal an event associated with a cursor occurring in the first terminal so as to obtain the position of the cursor;
means for informing the second terminal of the position information of the cursor such that the second terminal redraws the cursor on the screen of the second terminal using the received position information when the position of the cursor indicates that the cursor needs to be displayed on the screen of the second terminal;
means for authorizing, by the second terminal, the control right for the cursor so that the cursor can be moved on the screen of the display of the second terminal; and
means for calculating, at the second terminal, the movement position of the redrawn cursor based on the movement information received from the first terminal, and controlling an object on the display of the second terminal based on the input information received from the first terminal;
the second terminal comprising:
means for extending the display space of the second terminal to the first terminal;
means for intercepting at the second terminal an event associated with cursor occurring in the second terminal so as to obtain the position of the cursor;
means for informing the first terminal of the position information of the cursor such that the first terminal redraws the cursor on the screen of the first terminal using the received position information when the position of the cursor indicates that the cursor needs to be displayed on the screen of the first terminal;
means for authorizing, by the first terminal, the control right for the redrawn cursor so that the cursor can be moved on the screen of the display of the first terminal; and
means for calculating, at the first terminal, the movement position of the redrawn cursor based on the movement information received from the second terminal, and controlling an object on the display of the first terminal based on the input information received from the second terminal.
8. The system according to claim 7 , wherein the means for extending the display space of the first terminal to the second terminal comprise:
means for mapping the coordinate system of the first terminal to the coordinate system of the second terminal in arbitrary direction; and
the means for extending the display space of the second terminal to the first terminal comprise means for mapping the coordinate system of the second terminal to the coordinate system of the first terminal in arbitrary direction.
9. The system according to claim 7 , wherein the first terminal is connected to the second terminal over a network.
10. The system according to claim 9 , wherein said network comprises a wired network or a wireless network.
