Abstract

Technologies are generally described for a broadband passive sensing and tracking system that may employ a number of passive receivers that each have the capability of sensing electromagnetic waves (e.g., Radio Frequency "RF" signals) from surrounding broadcast sources. Each passive receiver may be adapted to sense through one or more antennas. Multiple receivers at different positions may be utilized to form a broadband sensing network adapted to perform collaborative tracking of a scene of interest. According to some examples, a beam-forming algorithm may be applied over the broadband sensing network utilizing an antenna array formed by the passive receivers to localize and track objects.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Patent Application Serial No. 12 / 719,797, filed March 8, 2010, entitled "BROADBAND PASSIVE TRACKING FOR AUGMENTED REALITY." The disclosure of this patent application is incorporated herein by reference for all purposes. Background technique [0003] Unless otherwise indicated herein, the materials described in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section. [0004] Augmented reality (AR) refers to a physical (real) world environment with elements augmented by virtual (typically computer-generated) imagery, creating a mixed reality. Traditionally, this augmentation is real-time and in the context of environmental factors, such as sporting events, military exercises, games, and the like. AR technology makes information about the real world around an individual interactive and digitally usable by add...
