An interactive camera system with virtual reality technology is provided. The system includes an augmented reality module, an accessory database, a voice database, and an integration module. The augmented reality module generates a virtual environment, and a user can combine a three-dimensional avatar substrate with a character image to form a three-dimensional avatar that displayed in the virtual environment. The accessory database and the voice database allow the user to select different accessory patterns and different voice modules for different types of three-dimensional avatar substrates. The integration module allows professional personnel to provide technical presentations, thesis introductions, or background introductions in the virtual environment, so that the presentations or the introductions can be performed with three-dimensional augmented reality effect.
