One system includes processor configured to define a first virtual zone around a piece of equipment, determine a location of a person, and define a second virtual zone around the person at the location. As the location of the person changes, the processor is further configured to determine a direction of travel of the person, and automatically modify the second virtual zone to extend a first distance in the direction of travel of the person and extend in a second distance opposite the direction, wherein the first distance is greater than the second distance. In response to at least a portion of the second virtual zone overlapping with at least a portion of the first virtual zone, the processor is configured to perform at least one action."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Proximity detection systems and methods","description":"Methods and systems for detecting a person located around a piece of equipment.
