<P>PROBLEM TO BE SOLVED: To directly execute three-dimensional position designation and image drawing corresponding to a three-dimensional image for projection. <P>SOLUTION: A projection system includes: an input unit 11 for inputting an image signal; a projection system (13-18) for projecting a left-eye image and a right-eye image, each having invisible position coordinate information superposed thereon, corresponding to the image signal input by the input unit 11; an antenna 26 and a pointer communication unit 24 for receiving information indicative of each position coordinate of the left-eye image and the right-eye image sent from a point device (2) and information indicative of the direction and the magnitude of external force given to the pointer device (2); and a CPU 19 for calculating, based on the received information, the designation position of the image, projected by the projection system (13-18), in a three-dimensional space, and for projecting an image obtained by adding a predetermined point image to the image projected by the projection system (13-18) according to the calculated designation position in the three-dimensional space. <P>COPYRIGHT: (C)2013,JPO&INPIT |
