Abstract

An information processing apparatus inputs an angular rate detected by a gyroscope included in an input device and displays an image on a display device. The information processing apparatus initially calculates an orientation of the input device based on the angular rate. Then, the information processing apparatus calculates a coordinate point at an intersection between a line extending from a predetermined position in a predetermined space toward a vector representing the orientation and a predetermined plane within the predetermined space. A display range of a display target that is to be displayed on the display device is controlled based on the coordinate point.
