INFORMATION-INPUTTING DEVICE INPUTTING CONTACT POINT OF OBJECT ON RECORDING SURFACE AS INFORMATION

An information-inputting device is provided which device includes a plurality of photographing units photographing an area on a plane; an object-recognizing unit extracting an object located on the plane from a photographed image, and recognizing whether the object is a specific object; a location-calculating unit calculating a contact position of the specific object on the plane from the photographed image if the object has been recognized as the specific object; and a data-storing unit storing information about a track of the contact position while the specific object is contacting the plane. The information-inputting device determines a shape of the object on the plane by use of the object-recognizing unit, and calculates the contact positions of the specific object by use of the location-calculating unit if the object has been determined as the specific object by the object-recognizing unit. Subsequently, the information-inputting device stores the track of the contact position while the specific object is contacting the plane. Thus, the information-inputting device can record data in a recording medium in real time while the data is being written on a recording surface without specifying types of writing implements and materials used for the recording surface.
