Problem Addressed

RF-based positioning has become the next frontier for innovation in mobile computing, business analytics, and human-computer interaction. Advancements in RF-based technology to-date have enabled the localization of RF sources to an accuracy of tens of centimeters. However, little has been done to further accurately track an RFID’s motion trajectory. This detailed, real-time motion tracking is critical for application of RF technology for gaming and gesture-based interfaces and requires a resolution several-fold higher than what existing RF-based localizing systems can offer.
