Abstract:
Systems and methods improve virtual reality and augmented reality functionality for mobile devices using radio frequency (RF) signals transmitted by a tracked device and received at four or more spatially separated antennae. These antennae are connected, wirelessly or through wired connections, to a base station. Through RF signal time of arrival information acquired at the antennae, the base station can continuously determine accurate position information of the tracked device, without lighting or line of sight limitations experienced by camera and other optical systems. As the position of the RF-transmitting tracked device is registered within a virtual environment produced by an interactive software program in communication with (or part of) the base station, the virtual viewpoint of the tracked device is controlled to reflect the relative position and orientation of the tracked device with respect to the virtual environment produced by the software program and displayed on a view screen.

Claim (Index 8):
A method of improving virtual reality or augmented reality interactions with a mobile device, the method comprising the steps of:\n measuring, by one or more inertial sensors of the mobile device, inertial data used to compute an orientation of the mobile device; transmitting, by the mobile device, radio frequency (RF) signals conveying RF data; receiving, by the mobile device, RF signals conveying a three-dimensional (3D) physical position of the mobile device determined from the RF data conveyed by the RF signals transmitted by the mobile device; displaying, by an interactive software program executing on the mobile device, a digital world on a view screen from a 3D viewpoint of the mobile device; dynamically updating, by the interactive software program, the 3D virtual viewpoint of the mobile device based on the three-dimensional physical position of the mobile device conveyed by the RF signals received by the mobile device and on the orientation of the mobile device computed from the inertial data measured by the one or more inertial sensors of the mobile device; and dynamically updating, by the interactive software program, the display of the digital world on the view screen in accordance with the dynamically updated 3D virtual viewpoint of the mobile device.
