Information display apparatus and information display program

An information display program executable in an information display apparatus for performing control based on a plurality of touch inputs from a multi-touch input panel, the information display program being adapted to cause the information display apparatus to perform a process comprising the steps:

• a contact-point acquisition step of acquiring a contact point on the multi-touch input panel;
• a multi-touch determination step of determining whether the contact point acquired through the contact-point acquisition step is a multi-touch;
• a touch-motion determination step of, when the contact point is determined as a multi-touch through the multi-touch determination step, determining a moving motion of the contact point;
• a page-number setting step of calculating and setting a turning-page number for a multi-page turning processing, based on the moving motion determined through the touch-motion determination step;
• and
• a page turning processing step of performing a page turning processing based on the turning-page number determined through the page-number setting step,
• wherein the page-number setting step includes:
• managing a distance during the contact-point moving motion, based on a plurality of segments for each of two moving motions in two directions;
• and calculating the turning-page number by multiplication between each of a plurality of multiple values assigned correspondingly to respective ones of the segments for the moving motion in one of the two directions, and a respective one of a plurality of page numbers assigned correspondingly to respective ones of the segments for the moving motion in the other direction.
