Abstract: A personal digital assistant includes a display control unit that causes an object as a target of the touch operation to be displayed in the image display unit, an image input unit that acquires a video of an operation instruction object that performs the touch operation on the touch screen, and a shaking detection unit that analyzes the video of the operation instruction object, which is acquired by the image input unit, and calculates a relative shaking amount of the operation instruction object to a position of the personal digital assistant as a reference. The display control unit causes the object to be displayed in the image display unit to be displayed, based on the relative shaking amount of the operation instruction object, which is calculated by the shaking detection unit, such that the object is shifted in accordance with the relative shaking amount.
