1. An information processing apparatus, comprising:
a transformation matrix calculation section configured to calculate a transformation matrix for converting coordinates of an input position of an input device within a projection region projected from a display apparatus from coordinates of an image coordinate system of a sensor apparatus having detected the input position to coordinates of a screen coordinate system of the display apparatus;
a scale calculation section configured to calculate a scale correction value for a display mode of a locus of the input position in reference to distance information regarding a distance between the display apparatus and the input position; and
an input display generation section configured to generate an input image depicting the locus of the input position through use of the transformation matrix and the scale correction value.
