System and control method for online brainstorming

A system for processing online brainstorming and a control method thereof are provided to process the online brainstorming by providing an online brainstorming tool performing a brainstorming conference in a web environment. A brainstorming conference manager(100) enables a chairman to manage each part to attain a goal of online brainstorming, and a messenger processor(200) enables joiners to join in the online brainstorming or interchange an opinion by including a messenger window. An idea card processor(300) transforms an idea of the joiner into data by including an idea card window. An idea board processor(400) represents the idea of the joiners by including an idea board window and operates the idea board window by interconnecting with the idea card window. The idea card processor allows the joiner to generate and store the idea card window, and moves contents of the idea card to the idea board window when the joiner loads the idea card window. The idea board processor allows the joiner representing the idea appointed by the conference manager to use the idea board and allows other joiners to view an idea representation process.
