Camera-based registration techniques use a camera to automatically align the geometry of large scale displays composed of multiple overlapping light projectors. We present a method to implement a laser-pointer interface for these displays which capitalizes on the presence of this camera in the display environment and its precomputed knowledge about the display geometry. We describe our camera-registration framework and laser pointer integration and detail the functionality provided to applications. Our laser pointer integration supports both single pointer and multipointer interaction.
