Abstract
Provided is an information processing apparatus that includes a transformation matrix calculation section, a scale calculation section, and an input display generation section. The transformation matrix calculation section calculates a transformation matrix that converts the coordinates of an input position of an input device within a projection region projected from a display apparatus from the coordinates of an image coordinate system of a sensor apparatus having detected the input position to the coordinates of a screen coordinate system of the display apparatus. The scale calculation section calculates a scale correction value for a display mode of the locus of the input position in reference to distance information regarding the distance between the display apparatus and the input position. The input display generation section generates an input image depicting the locus of the input position through the use of the transformation matrix and the scale correction value.
