PROBLEM TO BE SOLVED: To provide an information processing system, an information processing apparatus, an information processing method, and a program.SOLUTION: An information processing apparatus 500 includes: at least one camera 501 facing a display unit and acquiring an image of coordinate specifying means which specifies a position in a three-dimensional space; a transformation matrix holding unit 508 which holds a transformation matrix for transforming position coordinates of the image of the camera 501 into world coordinates which are position coordinates on a three-dimensional space where the display unit is located; a world coordinate calculation unit 503 which transforms position coordinates of the coordinate specifying means in the image, by means of the transformation matrix, into world coordinates; and a recalibration determination unit 504 which determines recalibration of the transformation matrix by use of image coordinates of a point specified by the coordinate specifying means and located in the image.SELECTED DRAWING: Figure 5 |
