An information processing apparatus includes a display section, a control section, a first movement information detecting section configured to detect an amount of movement from an initial point to a primary stopping point of an operator's index finger touching a touch panel; a second movement information detecting section configured to detect an amount of movement from an initial point to a primary stopping point of an operator's thumb touching the touch panel; an amount-of-value-change calculating section configured to calculate, from the amount of movement of the index finger, an amount of numerical value change at each numerical display switch; and a switching speed calculating section configured to calculate, from the amount of movement of the thumb, a switching speed at each numerical display switch. The control section allows the numerical display switch of the display section in the calculated amount of numerical value change at the calculated switching speed.
