Properties of shadow-cursor for calibrating screen coordinates of tabletop displays

Abstract

This manuscript introduces the basic idea of a shadow-cursor for calibrating the screen coordinates of tabletop displays. The shadow-cursor is an invisible mouse cursor. We explain how the shadow-cursor works to calibrate the screen coordinates and discuss its properties of accuracy, and then show that the shadow-cursor has the potential to align the screen coordinates. © 2011 Springer-Verlag.
