Abstract
The position detection method includes projecting a detecting image on a projection surface from a projection section, taking, by an imaging section, an image of the projection surface in a first direction from the projection section in a situation in which the detecting image is projected on the projection surface and a pointing body touches the projection surface to thereby generate imaging data, and detecting a position of a touch portion by the pointing body on the projection surface based on the imaging data, wherein the detecting image represents a plurality of objects located in a matrix and the position of the touch portion is detected based on a positional relationship in the predetermined direction corresponding to a first direction of the plurality of objects represented by the imaging data.
