Briefly, in accordance with one or more embodiments, an image or projection cone is projected onto a projection surface via a raster scan to generate the image, or in a light cone. Movements of two or more input sources with respect to projection cone are detected, and a determination is made whether the input sources have crossed a crossover line in the projection cone. If the input sources have moved greater than a threshold amount after crossing the crossover line, position data between the input sources may be exchanged to reflect proper position data for the input sources. |
