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 from the 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;

    identify the 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 rate of 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 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.
