<P>PROBLEM TO BE SOLVED: To provide good operability irrespective of the number of operators who simultaneously operate. <P>SOLUTION: A center position of a body of an operator is left as it is on an Xd-Yd plane of a screen coordinate system. The center position serves as an original point of an operator coordinate system, and a display position of a pointer Po is calculated based on a position of a hand from the original point. A range in which the hand of the operator reaches easily is determined, and based on this range and a size of a GUI screen 130, a ratio of scaling on the position of the hand is set so that the pointer Po moves to an end of the screen when the hand moves to an end of this range. <P>COPYRIGHT: (C)2011,JPO&INPIT |
