Speaker detection in a virtual classroom using 3D triangulation

Virtual classroom creates an environment in which the students and professors at different physical locations can interact through internet. But one of the main issues with the virtual classroom approach is that it cannot ever bring up the environment of a real classroom, so the interaction between the speaker and the professor cannot be in a natural manner. Using 3-Dimensional triangulation, the localization of the active speaker can be determined and the interaction between the professor and the students can be enhanced.
