Action data generation device and client and system for information transmission
First Claim
1. A system for information transmission, comprising a plurality of clients for information transmission, each client comprising:
- an action input unit for receiving action information on an interface and sending the action information to an action data generation unit;
the action data generation unit, for receiving action information input by the action input unit and generating action data according to the action information, wherein action data includes a path part and a data part, wherein, for each instance of action information received from the action input unit, the path part consists of coordinates of a contact point on the interface or a physical coordinate change sequence of an action path on the interface characterizing a change of physical coordinates of a contact points on the interface, and the data part consist of a file path, binary file data, or no data;
a sending unit for sending separately the path part and the data part of the action data generated by the action data generation unit to any other client in the system;
a receiving unit for receiving action data from any other client in the system;
an action information reconstructing unit for reconstructing, from the received action data, action information for display on the interface based on the action data received by the receiving unit; and
a display unit for displaying the action information reconstructed by the action information reconstructing unit,wherein at least one client operates in a controlling mode, and at least one client operates in a controlled mode; and
wherein the client operating in the controlled mode, after being authorized by the client operating in the controlling mode, activates the action input unit, the action data generation unit and the sending unit of the client operating in the controlled mode.
