INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING APPARATUS, METHOD OF TRANSFORMING COORDINATES

摘要

An information processing system includes a pointer to designate a position in a three-dimensional space relative to a display, a first image capture device to capture the position designated by the pointer relative to the display as a virtual image of the pointer, a parameter calculator to calculate a first parameter used for transforming coordinates of the position designated by the pointer in the virtual image to world coordinates when the pointer is operated on the display by touching the display, or a second parameter used for transforming coordinates of the position designated by the pointer in the virtual image when the pointer is operated above the display without touching the display, and a world coordinate calculator to transform the coordinates of the position designated by the pointer in the virtual image to the world coordinates by applying the first parameter or the second parameter.

1. An information processing system comprising:
a pointer to designate a position in a three-dimensional space relative to a display; a first image capture device to capture the position designated by the pointer relative to the display as a virtual image of the pointer; a parameter calculator to calculate a first parameter used for transforming coordinates of the position designated by the pointer in the virtual image to world coordinates when the pointer is operated on the display by touching the display, or a second parameter used for transforming coordinates of the position designated by the pointer in the virtual image when the pointer is operated above the display without touching the display; and a world coordinate calculator to transform the coordinates of the position designated by the pointer in the virtual image to the world coordinates by applying the first parameter or the second parameter calculated by the parameter calculator.
