Displaying information based on wireless ranging

A wireless device, comprising:

• an interface circuit configured to communicate wirelessly with a tag;
• a processor, communicatively coupled to the interface circuit, configured to execute a program module;
• a display;
• and
• a memory, communicatively coupled to the processor, configured to store the program module, wherein the program module comprises instructions for:
• determining that an object associated with a tag is known to the wireless device based on an anonymous identifier included in a wireless transmission received from the tag;
• performing a wireless ranging operation, responsive to determining the object is known to the wireless device, the wireless ranging operation including:
• transmitting a wireless signal including an identifier encoded on the wireless signal to the tag;
• and
• receiving a response from the tag, wherein the tag responds to the wireless signal responsive to recognizing the identifier encoded on the wireless signal;
• determining a location of the tag relative to the wireless device based on the wireless ranging operation, the location of the tag comprising a direction and a range;
• determining a direction to which the display of the wireless device is oriented relative to the location of the tag;
• and
• based on the determined direction, presenting output information that indicates a location of the object relative to the wireless device.

A non-transitory computer-readable medium storing instructions for displaying information for one or more objects associated with a wireless device, the instructions comprising:

• instructions for determining that an object associated with a tag is known to the wireless device based on an anonymous identifier included in a wireless transmission received from the tag;
• instructions for performing a wireless ranging operation, responsive to determining the object is known to the wireless device, the wireless ranging operation including:
• transmitting a wireless power signal including an identifier encoded on the wireless power signal to the tag;
• and
• receiving a response from the tag, wherein the tag responds to the wireless power signal responsive to recognizing the identifier encoded on the wireless power signal;
• instructions for determining a location of the tag relative to the wireless device based on the wireless ranging operation, the location of the tag comprising a direction and a range;
• instructions for determining a direction in which a display of the wireless device is facing;
• and
• instructions for presenting output information, based on the determined direction, that indicates a location of the object relative to the wireless device.
