Embodiments relate to selecting an object to display from an information processing device connected in a manner enabling the exchange of data to a touch panel having a display function. An aspect includes entering a trajectory extension mode in response to the user moving a finger over the touch panel at a speed equal to or greater than a predetermined speed. Another aspect includes extending and displaying a trajectory of the finger in response to the speed of the moving finger detected in the trajectory extension mode. Yet another aspect includes placing an object located at an end point of the extended trajectory on the touch panel in a selected state.
