The nature of information is digital and discrete. It is invisible, but we can depict it with mathematical science.Each student handles his/her individual research problem.Discussion with the peers is important tosolve it. We must develop partnership and friendship.Block diagram of brain computer interface systemEye-gaze input systemRevealing the Limits of the Source Coding ProblemsDevelopment of the User Friendly Computer Interface
