SPATIAL POSITION INDICATION SYSTEM

A spatial position indication system is provided which enables an operator of an electronic pen to perform drawing while seamlessly switching between drawing by line drawing and drawing by gesture.The spatial position indication system includes an electronic pen, an indicated position detecting device unit, a spatial position detecting device unit, and a selecting unit. The indicated position detecting device unit detects a position indicated by the electronic pen in a detection region including a hover region over an input surface. The spatial position detecting device unit detects the position of the electronic pen in a spatial region including at least a part of the hover region of the indicated position detecting device unit separately from and independently of the indicated position detecting device unit. On the basis of detection output of the position indicated by the electronic pen and spatial position detection output, the selecting unit performs selection control so as to use one of the indicated position detection output and the spatial position detection output according to a separation distance of the electronic pen from the input surface when a drawing image to be displayed on a display unit is generated.
