Abstract
A three-dimensional image sensor for detecting the three-dimensional position of an object, a coordinate detection unit for detecting the coordinate position of an objective point on a display screen based on the position of the object in a virtual pointing space, a movement detection unit for detecting the three-dimensional movement of the object in the pointing space, and an operation input contents determination unit for determining an operation based on the three-dimensional movement or the like of the object are provided, so that the inconvenience of moving a pointing device such as a finger to a fixed spatial plane is avoided by setting the pointing space which can be operated by the pointing device as a pyramid shape defined by connecting the display screen and a reference point.
