Patent attributes
A method and data processing device for detecting and tracking objects in a space. The method includes transmitting an inquiry signal that traverses into the space, which is behind a physical barrier and is pre-configured with a plurality of radio frequency identification (RFID) tags. The method includes monitoring for a corresponding response signal. In response to not detecting the corresponding response signal, an RFID reader module transmits a second signal. The method includes monitoring for and recording a RFID response signal, which is generated in response to the second signal impinging on the RFID tag and one or more objects in the space. The method includes extracting a reflection signal from the response signal to determine the presence of an unknown object. The method includes tracking the unknown object within the space, and providing more specific position data of the unknown object to a display of an electronic device.
