Abstract:
1. An interactive presentation system for providing instructions regarding a projected image through interactive operations, the interactive presentation system comprising: an imaging device configured to capture an image over an imaging area including an area of the projected image and outside of the area of the projected image; an image analysis device configured to calculate positional information regarding a pointed position by using image data of the image captured by the imaging device; a control device configured to receive the positional information calculated by the image analysis device as an input and operate based on information inputted from an input device; a storage device configured to store the positional information calculated by the image analysis device under control of the control device; an image display device; and a projector configured to enlarge and project an output from the image display device; wherein in an initialization stage in which initialization is conducted based on the information inputted from the input device, the control device stores, in the storage device, a boundary position of a command, which defines an operation area to be set outside the area of the projected image in the imaging area, with a predetermined command being assigned to the operation area, and the control device compares a pointed position obtained via the imaging device and the boundary position stored in the storage device in the initialization stage, and executes the predetermined command associated to the positional information regarding the pointed position.
