ABSTRACT:
An information-inputting device is provided, which includes a plurality of photographing units photographing an area on a plane. An object located on the plane is then extracted from an image that includes the plane and the object, and it is determined whether the object is a specific object. If the object is the specific object, a position of a contact point between the specific object and the plane is calculated.
