Information processing apparatus installed with touch panel as user interface

The present invention provides an information processing apparatus installed with a touch panel as user interface. The information processing apparatus includes a detection unit capable of detecting first and second touch positions on a touch panel touched by first and second objects, respectively, a storage unit that stores the first and second touch positions and holds a final touch position as the touch position after each touch is released, a calculation unit that calculates a position obtained by a predetermined rule from the first and second touch positions stored by the storage unit, and a determination unit that determines whether an operation performed on the touch panel is an operation of moving a display content displayed on the touch panel, or an operation of rotating or changing a size of a display content displayed on the touch panel, based on whether the position calculated by the calculation unit is moved, a speed of movement, or an amount of movement.
