Displaying information based on wireless ranging

A wireless communication device, comprising:

• an interface circuit configured to communicate wirelessly with an object proximate to the wireless communication device using at least one wireless communication protocol;
• a processor, communicatively coupled to the interface circuit, configured to execute a program module;
• and
• a memory, communicatively coupled to the processor, configured to store the program module, wherein the program module includes instructions for:
• receiving, from the object proximate to the wireless communication device via a wireless personal area network (WPAN) or wireless local area network (WLAN), a transmission that includes an anonymous identifier;
• determining, based at least on the anonymous identifier, whether the object is associated with the wireless communication device;
• and
• when the object is associated with the wireless communication device:
• waking up a wireless communication interface from a power-reduced state to perform a wireless ranging operation;
• performing the wireless ranging operation using the wireless communication interface to determine a location of the object relative to the wireless communication device;
• and
• responsive to the location of the object exceeding a threshold distance from the wireless communication device, generating a notification on a user interface of the wireless communication device, the notification providing a reminder to maintain a proximity of the object to the wireless communication device within the threshold distance.

A computer-program product for use in conjunction with a wireless communication device, the computer-program product comprising a non-transitory computer-readable storage medium and a computer-program mechanism embedded therein to generate a notification associated with an object proximate to the wireless communication device, the computer-program mechanism including:

• instructions for receiving, by the wireless communication device from the object proximate to the wireless communication device via a wireless personal area network (WPAN) or wireless local area network (WLAN), a transmission that includes an anonymous identifier;
• instructions for determining, by the wireless communication device based at least on the anonymous identifier, whether the object is associated with the wireless communication device;
• and
• instructions for, when the object is associated with the wireless communication device:
• waking up a wireless communication interface from a power-reduced state to perform a wireless ranging operation;
• performing the wireless ranging operation using the wireless communication interface to determine a location of the object relative to the wireless communication device;
• and
• generating, by the wireless communication device responsive to the location of the object exceeding a threshold distance from the wireless communication device, the notification on a user interface of the wireless communication device, the notification providing a reminder to maintain a proximity of the object to the wireless communication device within the threshold distance.
