The information about children's behavior stems from a personal pipeline Santa Claus has to children's thoughts via a listening antenna that combines technologies currently used in cell phones and EKGs. A sophisticated signal processing system filters the data, giving Santa clues on who wants what, where children live, and even who has been bad or good. Effectively, it gives him advanced neuroimaging capabilities that tell him that Mary in Miami hopes for a surfboard, Michael from Minneapolis wants a snowboard, etc. Later, all this information is processed in an onboard sleigh guidance system, which provides Santa with the most efficient delivery route. The system serves as a fail-safe backstop to the letters Santa receives via snail mail from around the globe.
