Abstract
An interactive presentation system includes: an imaging device; an image analyzer that calculates information regarding a pointed position by using captured-image data; a controller that receives the information and operates based on an input from an input device; a storage device controlled by the controller to store the information; a pattern generator controlled by the controller to generate a pattern image; an image display device that receives an output from the pattern generator; and a projector that enlarges and projects an output from the image display device. Upon initialization based on the input from the input device, the controller defines a pointed position as a boundary position of a command, assigns the command to an area demarcated by the boundary position, and stores the boundary position in the storage device. After initialization, the controller compares a pointed position and the boundary position and executes the command associated to the information.
