A system and method for providing immersive interaction between users and interactive software programs comprise receiving radio frequency (RF) signals, transmitted by an RF-transmitting device, at three or more spatially separated antennas. Time of arrival information is acquired from the RF signals. A position of the RF-transmitting device is computed from the time of arrival information acquired from the RF signals. The position of the RF-transmitting device is registered within a virtual environment produced by an interactive software program (which can execute on a mobile device). The virtual environment, as affected by the registered position of the RF-transmitting device, is transmitted to a display apparatus for display.
