The apparatus may also include at least one radar device that (1) transmits a frequency-modulated radar signal to the transponder and (2) receives signals whose frequencies are within the certain frequency range. In addition, the apparatus may include a processing device that (1) detects a signal returned to the radar device from the transponder, (2) calculates, based on the returned signal, a distance between the transponder and the radar device, and then (3) determines, based on the distance between the transponder and the radar device, a current physical location of at least a portion of the user. Various other apparatuses, systems, and methods are also disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Devices, systems, and methods for radar-based artificial reality tracking","description":"The disclosed apparatus may include at least one transponder that (1) is located on a wearable device worn by a user and (2) retransmits signals received at the transponder after shifting frequencies ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11474227","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
