The keeper's note
Detects human-object interactions by reading signals from a wireless RFID tag antenna embedded in the object.
Abstract
There are provided systems and methods for a user interaction with an object having awireless tag with an antenna. An example system includes a memory storing a tag processing software, and a hardware processor executing the tag processing software to receive a signal from the wireless tag of the object via the antenna, the signal including a wireless tag identification (ID) uniquely identifying the wireless tag, identify the object using the wireless tag ID, extract one or more communication channel parameters from the signal, determine the user interaction with the object based on the one or more communication channel parameters extracted from the signal.

Claims
1. A system for determining an interaction of a user with an object based on a state of the object having a wireless tag with an antenna for reading by a wireless tag reader, the system comprising: a memory storing a tag processing software; and a hardware processor executing the tag processing software to: receive, from the wireless tag reader over a period of time, a plurality of signals fromthe wireless tag of the object via the antenna, each signal of the plurality of signals being for a successful read of the wireless tag, each signal of the plurality of signals including a wireless tag identification (ID) uniquely identifying the wireless tag; identifythe object using the wireless tag ID; determine, over the period of time, wireless channel parameters based on the plurality of signals, the wireless channel parameters including a signal strength indicator (RSSI) of each signal of the plurality of signals, a read rateof the plurality of signals, and an RF phase of each signal of the plurality of signals; classify, based on analyzing the RSSI of the plurality of signals, the read rate of the plurality of signals, and the RF phase of the plurality of signals over the period of time, the state of the object as one of still, moving, and rotating; and determine the user interaction with the object based on the state of the object, the user interaction including keeping the object still, moving the object, rotating the object, and covering the object; wherein the read rate corresponds to a number of successful reads of the wireless tag overthe period of time; and wherein the covering of the object is determined based on the read rate of the wireless tag over the period of time being less than a predetermined number over the period of time.
8. A method of determining an interaction of a user with an object based on a state of the object having a wireless tag with an antenna for reading by a wireless tag reader, the method using a system having a memory storing a tag processing software and a processor executing the tag processing software, the method comprising: receiving, from the wireless tag reader over a period of time using the processor, a plurality ofsignals from the wireless tag of the object via the antenna, each signal of the pluralityof signals being for a successful read of the wireless tag, each signal of the plurality of signals including a wireless tag identification (ID) uniquely identifying the wireless tag; identifying, using the processor, the object using the wireless tag ID; determining, using the processor and over the period of time, wireless channel parameters based on the plurality of signals, the wireless channel parameters including a signal strength indicator (RSSI) of each signal of the plurality of signals, a read rate of the plurality of signals, and an RF phase of each signal of the plurality of signals; classifying, using the processor, based on analyzing the RSSI of the plurality of signals, the read rate of the plurality of signals, and the RF phase of the plurality of signals over the period of time, the state of the object as one of still, moving, and rotating; and determine, using the processor, the user interaction with the object based on the state of the object, the user interaction including keeping the object still, moving the object, rotating the object, and covering the object; wherein the read rate corresponds to a number of successful reads of the wireless tag over the period of time; and wherein the covering of the object is determined based on the read rate of the wireless tag over the period of time being less than a predetermined number over the period of time.
