Abstract
Reporters obtained the following quote from the background information supplied by the inventors: “There are many cases in which physical devices are used in a variety of settings involving groups of people and/or objects, such as in the fo rmation of posts and lines to demark crowd control areas or permitted pathways f or movement.These provide regions which may be fluid, and tend to require manpo wer to continually reconfigure them.The posts themselves provide opportunities for gathering/inferring/presenting/rendering/conveying information which may be optical, visual, or otherwise.Robotic devices of this sort may serve a variety of purposes in both gathering/ inferring/presenting/rendering/conveying informati on and demarking areas.”
