<P>PROBLEM TO BE SOLVED: To provide an information processing system and a program thereof capable of performing a highly precise calibration process of position coordinates on a display screen in display means of a computer device. <P>SOLUTION: An information processing system 10 includes: a screen 4 formed with a coded pattern indicating position coordinates; an electronic pen 1 reading the coded pattern; a computer device 2 receiving information related to the coded pattern transmitted from the electronic pen 1 and processing according to the information; and a projector 3 receiving image signals from the computer device 2 and projecting an image to the screen 4. In the calibration process, when recognizing a plurality of pen touches with respect to a projected specific calibration mark, the computer device 2 determines which position coordinates of the pen touches are adopted as the position coordinates corresponding to the specific calibration mark based on whether or not the position coordinates of the plurality of pen touches are present within a same recognition range and whether or not the pen touches are performed within a predetermined time range. <P>COPYRIGHT: (C)2012,JPO&INPIT |
