<P>PROBLEM TO BE SOLVED: To provide an interactive system which reduces situations in which information from a transmitter cannot be detected. <P>SOLUTION: An interactive system 1 includes a plurality of projectors 100 and 200, a computer 300, and a transmitter (light-emitting pen 400) which transmits an optical signal. The plurality of projectors are installed so that projected images projected by respective projectors are displayed one over the other in one projection area. Each projector includes an imaging unit 50 or 250 which images a range including the projected image and forms first optical signal information based on an optical signal, and an optical signal output unit for outputting the optical signal to the computer 300. The computer 300 includes: an optical signal input unit which receives a plurality of pieces of first optical signal information; an optical signal information processing unit which forms second optical signal information on the basis of the plurality of pieces of first optical signal information; and an object operation unit which operates an object included in an image represented by an image signal, on the basis of the second optical signal information. <P>COPYRIGHT: (C)2013,JPO&INPIT |
