Abstract
A method and apparatus for transcribing composite images. In one embodiment, a method comprises projecting a first image onto a surface, wherein a first coordinate system defines positions within the first image and a second coordinate system defines positions on the surface. The method further comprises forming a second image on the surface by using a stylus, and recording the formation of the second image relative to the first image by periodically detecting the position of the stylus relative to the second coordinate system by receiving and processing signals transmitted from the stylus. The method also comprises translating the position of the stylus relative to the second coordinate system to a position relative to the first coordinate system, and storing the composite image comprising the first image and the second image as machine-readable data.
