Information processing apparatus, information processing method and computer program
There is provided an information processing apparatus according to the present invention including a detection unit for detecting a moving direction and a moving amount of a finger on an operation panel, and a moving control unit for changing the moving amount of an object on a display unit for a finger's unit moving amount depending on the moving direction of the finger which moves the object displayed on the display unit.
