Classification: CPC H  G | IPC G  H

Claim 14:
15. A computer program product comprising:
a computer readable storage device; and
program code on the computer readable storage device that when executed within a processor associated with a user device, the program code enables the user device to provide functionality of:
receiving, by a user device, at least one radio frequency identification (RFID) response signal from a tag antenna corresponding to a respective tag of an object in a space located within a detectable distance of the user device, each RFID response signal having a unique tag identification (ID) of the respective tag modulated thereon;
in response to receiving the corresponding RFID response signal from the respective tag within the space, identifying, by a processor, a directional location of the respective tag relative to the user device, the directional location including a general horizontal position within the space and a general vertical position within the space;
estimating, based on a signal strength and the directional location of the corresponding RFID response signal, a distance of the respective tag relative to the user device;
correlating the directional location and distance of the respective tag to generate a more precise point location of the object within the space; and
outputting the corresponding distance and horizontal and vertical position information to provide the more precise point location of the object within the space.
