1. An interactive presentation system, comprising:
an active infrared camera, arranged in front of a presenter, for taking a visible image and an infrared image of the presenter;
a command recognition system connected to the active infrared camera to perform a gesture recognition algorithm upon receipt of the infrared image of the presenter from the active infrared camera and outputting a corresponding command;
an image synthesis system connected to the active infrared camera to synthesize the visible image of the presenter received from the active infrared camera and a presentation material, and connected to the command recognition system to control the presentation material upon receipt of a command signal outputted from the command recognition system; and
a screen arranged in front of the presenter to display the synthesized visible image and the presentation material received from the image synthesis system, so that the presenter can perform a presentation while viewing the visible image of the presenter synthesized with the presentation material in real time.
