The Finnish developer of Blind Square told AppleVis in a recent
interview that he created an algorithm that determines someone’s
walking speed by measuring the distance between multiple inquiries to
the server, which can only be accessed every five seconds. The
algorithm can then accurately project someone’s location between
server inquiries. If a single developer working in his spare time can
do this, why can’t the full time Sendero team accomplish the same
thing?
