Network system based on remote user interface protocol and method of operating server and client of network system, and computer-readable medium having embodied thereon computer program for executing method of operating server and client of network system

A server for providing a virtual pointing device service in a network system which is based on a remote user interface protocol and includes a plurality of clients, the server comprising:

• a user interface information generating unit which generates at least pointing device user interface information;
• a communication unit which is communicably linked to at least one of the clients;
• and
• a control unit which controls the user interface information generating unit to generate pointing device user interface information, and transfers the generated pointing device user interface information to the communication unit, if a request for providing the virtual pointing device service is received from the communication unit.

A client which can provide a virtual pointing device service in a network system which is based on a remote user interface protocol and includes a server which can provide the virtual pointing device service, the client comprising:

• a command receiving unit which receives a user command;
• a communication unit which is communicably linked to the server;
• a display unit which displays a pointing device user interface screen based on pointing device user interface information;
• and
• a control unit which transfers a request for providing the virtual pointing device service to the communication unit, and controls the display unit to display the pointing device user interface screen if pointing device user interface information is received from the communication unit.

A method of operating a server for a virtual pointing device service in a network system including a server and a plurality of clients, the method comprising:

• transferring pointing device user interface information to at least one of the clients if a request for providing a virtual pointing device service is received from the at least one of the clients;
• updating location information of a pointing device based on pointing information if pointing information is received from the at least one of the clients;
• and
• generating pointing device user interface information based on updated location information of the pointing device, and transfers the generated pointing device user interface information to the at least one of the clients, if location information of the pointing device is updated.

A method of operating a client for a virtual pointing device service in a network system including a server and a plurality of clients, the method comprising:

• transferring a request for providing a virtual point device service to the server;
• displaying a screen in which pointing device user interface information is overlaid with remote user interface information if pointing device user interface information is received from the server;
• transferring a command to the server when the command is input based on the displayed screen;
• and
• displaying user interface information received from the server based on the input command.

A computer-readable medium having embodied thereon a computer program for executing a method of operating a server for a virtual pointing device service in a network system including a server and a plurality of clients, the method comprising:

• transferring pointing device user interface information to at least one of the clients if a request for providing a virtual pointing device service is received from the at least one of the clients;
• updating location information of a pointing device based on pointing information if pointing information is received from the at least one of the clients;
• and
• generating pointing device user interface information based on updated location information of the pointing device, and for transferring the generated pointing device user interface information to the at least one of the clients, if location information of the pointing device is updated.

A computer-readable medium having embodied thereon a computer program for executing a client operation method for a virtual pointing device service in a network system including a server and a plurality of clients, the method comprising:

• transferring a request for a providing a virtual pointing device service to the server;
• displaying a screen in which pointing device user interface information is overlaid with remote user interface information if pointing device user interface information is received from the server;
• transferring a command to the server if the command is input based on the displayed screen;
• and
• displaying user interface information received from the server based on the input command.

A server which can provide a remote user interface service in a network system which is based on a remote user interface protocol and includes a plurality of clients, the server Comprising:

• a user interface information generating unit which generates remote user interface information;
• a communication unit which is communicably linked to at least one of the clients;
• and
• a control unit which controls the remote user interface information generating unit to generate remote user interface information based on the pointing device moving event, and transfers the generated remote user interface information to the communication unit, if the pointing device moving event and location information corresponding thereto are received from the communication unit.

A client which can provide a remote user interface service in a network which is based on a remote user interface protocol and includes a server which can provide the remote user interface service, the client comprising:

• a pointing device;
• a communication unit which is used for communication between the server and the client;
• a display unit which displays a remote user interface screen;
• a pointing device handler which monitors the pointing device and generates a pointing device moving event;
• and
• a control unit which transfers the pointing device moving event and location information corresponding to the server through the communication unit if the pointing device moving event is generated from the pointing device handler, and controls the display unit to display the remote user interface screen based on remote user interface information if remote user interface information is received from the server.
