Direction determination of a wireless tag

A method, comprising:

• receiving wireless signal replies that include signal strength indicators from a wireless tag responsive to wireless communications from a mobile device to the wireless tag, the wireless tag being physically placed in or affixed to an object;
• tracking movement of the mobile device based on motion sensor inputs to identify a location of the mobile device;
• determining a rotational orientation of the mobile device in a three-dimensional space at the location;
• and
• determining a direction toward the wireless tag in the three-dimensional space relative to the location of the mobile device based on the signal strength indicators in the wireless signal replies from the wireless tag and the rotational orientation of the mobile device in the three-dimensional space.

A method, comprising:

• receiving identification responses that include signal strength indicators from one or more RFID tags responsive to interrogation signals transmitted from a RFID reader;
• tracking movement of the RFID reader in a three-dimensional space based on motion sensor inputs to identify a location of the RFID reader;
• determining a rotational orientation of the RFID reader in the three-dimensional space;
• and
• determining a direction toward each of the one or more RFID tags in the three-dimensional space relative to the location of the RFID reader based on the signal strength indicators in the identification responses from respective ones of the one or more RFID tags and the rotational orientation of the RFID reader in the three-dimensional space.
