Method and system for indoor geolocation and access control

A non-transitory computer-readable device having instructions thereon that, when executed by at least one computing device, cause the at least one computing device to perform operations comprising:

• collecting environment information by a first reader device configured to control access to a first secure area via first ultrasound communications;
• determining first input information based on the environment information, the first input information including exit information captured by a door sensor at a door of the first secure area wherein the exit information is determined based on whether a request to exit has been received by the first reader device;
• determining, via a machine learning model, access intention information identifying the first secure area or a second secure area as an object of interest based on the exit information included in the first input information and second input information, wherein the second input information is associated with a second reader device that controls access to the second secure area and is co-located with the first reader device;
• and
• providing, based on the access intention information, access to one of the first secure area or the second secure area.

A system comprising:

• a memory storing instructions thereon;
• and
• at least one processor coupled with the memory and configured by the instructions to:
• collect environment information by a first reader device configured to control access to a first secure area via first ultrasound communications;
• determine first input information based on the environment information, the first input information including exit information captured by a door sensor at a door of the first secure area wherein the exit information is determined based on whether a request to exit has been received by the first reader device;
• determine, via a machine learning model, access intention information identifying the first secure area or a second secure area as an object of interest based on the first input information and second input information, wherein the second input information is associated with a second reader device that controls access to the second secure area and is co-located with the first reader device;
• and
• provide, based on the access intention information, access to one of the first secure area or the second secure area.
