UWB-based intent detection for seamless access

An access control device, comprising:

• an ultra wideband (UWB) subsystem configured to perform a ranging session with a mobile device and generate UWB data indicative of a distance of the mobile device from the access control device and an angle of arrival of a UWB signal from the mobile device;
• a light display positioned on an outer surface of the access control device and having a plurality of light segments;
• a processor;
• and
• a memory comprising a plurality of instructions stored thereon that, in response to execution by the processor, causes the processor to:
• receive the UWB data from the UWB subsystem;
• perform predictive analysis on the UWB data to generate expected location data associated with a location of the mobile device;
• determine a velocity of the mobile device and a heading of the mobile device based on the UWB data;
• determine whether the mobile device is on course to a dynamic target associated with a passageway secured by the access control device based on the velocity and the heading of the mobile device, wherein a width of the dynamic target is a function of a velocity of the mobile device and an angle of the mobile device relative to a center of the dynamic target;
• perform state estimation to determine whether the mobile device is within a secure distance threshold from the passageway, wherein the secure distance threshold dynamically changes based on the velocity of the mobile device;
• infer ingress intent of a user of the mobile device in response to determining that the mobile device is within the secure distance threshold and on course to the passageway;
• select a number of the plurality of light segments to illuminate based on the distance of the mobile device from the access control device;
• and
• illuminate the selected number of light segments.
