The keeper's note

Determines interaction states of a wireless tag attached to an object by sending an interrogation signal and analyzing the tags response.

Abstract

There is provided a system including a wireless tag reader, a wireless tag attached to an object, a non-transitory memory storing an executable code, and a hardware processor executing the executable code to transmit, using the wireless tag reader, an interrogationsignal, receive, using the wireless tag reader, a tag signal from the wireless tag attached to the object, in response to the interrogation signal, the tag signal including a wireless tag identification uniquely identifying the wireless tag, determine a tag state associated with the wireless tag using a probabilistic estimate based on the tag signal received from the wireless tag, and determine an interaction state of the object based on the tagstate of the wireless tag attached to the object.

Claims

1: A system comprising: a wireless tag reader; a wireless tag attached to an object; a non-transitory memory storing an executable code and a probability distribution of previous tag states of the wireless tag determined based on previous user interactions with the wireless tag; a hardware processor executing the executable code to: transmit, using the wireless tag reader, an interrogation signal; receive, using the wireless tag reader, a tag signal from the wireless tag attached to the object, in response to the interrogation signal, the tag signal including anelectronic product code (EPC) uniquely identifying the wireless tag; use the tag signal received from the wireless tag to probabilistically determine a current tag state of the wireless tag using the probability distribution of the previous tag states of the wireless tag; and determine an interaction state of the object based on the tag state of the wireless tag attached to the object. 11: A method for use with a system including a wireless tag reader, a non-transitory memory storing a probability distribution of previous tag states of a wireless tag determined based on previous user interactions with the wireless tag, and a hardware processor, the method comprising: transmitting, using the wireless tag reader, an interrogation signal; receiving, using the wireless tag reader, a tag signal from thewireless tag attached to an object in response to the interrogation signal, the tag signal including an electronic product code (EPC) uniquely identifying the wireless tag; using the tag signal received from the wireless tag to probabilistically determine a current tagstate of the wireless tag using the probability distribution of the previous tag states of the wireless tag; and determining, using the hardware processor, an interaction state ofthe object based on the tag state of the wireless tag attached to the object. 20: The method of claim further comprises updating the probability distribution using the current tagstate.
