Abstract
A position detection device includes a detection section adapted to detect an operation to a screen, a detection control section adapted to identify the pointing element with which the operation is performed, and associate the operation with the pointing element, and a processing section adapted to process the operation associated with the pointing element out of the operations. In the case in which a first operation and a second operation, which is performed within a predetermined period of time before the first operation, with a single pointing element are detected, and a coordinate of the first operation and a coordinate of the second operation are located within a predetermined range, the detection control section treats the coordinate of the first operation as the same coordinate as the coordinate of the second operation. Further, the detection control section changes the predetermined range in accordance with the detection position in the screen.
