Reporters obtained the following quote from the background information supplied by the inventors:“Augmented reality (AR) is an interactive experience of a real-world environment whereby the objectsthat reside in the real-world are augmented by overlaying computer-generated perceptual information. Theoverlaid information may be additive to the natural environment.“There are several AR techniques to render virtual images over real-world objects. Simultaneous Localizationand Mapping (SLAM) is an AR technique that localizes sensors with respect to their surroundings,while at the same time maps the structure of the environment. Recognition-based (or marker-based) ARuses a camera to identify visual markers or objects to showcase an overlay only when the marker is sensedby the device. Location-based AR relies on GPS, a digital compass, a velocity meter, or an accelerometerto provide data about location, and the AR visualizations are activated based on these inputs.
