Claim of US Patent No. 9,600,066

1. A 3D human-machine interaction method, comprising steps of: configuring an electronic tag with an ID for a hand; configuring
a Radio Frequency (RF) electromagnetic field containing a 3D virtual human-machine interface imaging space;
after the hand enters the RF electromagnetic field, acquiring information on the electronic tag on the hand;
acquiring coordinates, moving velocities, moving directions, and moving tracks of a finger and/or a palm part in the 3D virtual
human-machine interface imaging space according to the acquired information on the electronic tag;

matching the coordinates to a control or hot spot displayed in the 3D virtual human-machine interface imaging space;
determining whether a movement of the finger and/or the palm part matches a movement defined for touch control of the control
or hot spot in the 3D virtual human-machine interface imaging space; and when the movement of the finger and/or the palm part
matches the movement defined for touch control of the control or hot spot, triggering operation of the control or hot spot
in the 3D virtual human-machine interface imaging space,

wherein the step of acquiring information on the electronic tag on the hand comprises steps of:
performing contactless RF signal coupling of a Radio Frequency Identification (RFID) read-write module in a terminal and the
electronic tag through a coupling element; transferring energy and exchanging data between the RFID read-write module and
the electronic tag within a coupling channel; and after the data exchange, acquiring, by the terminal, the information on
the electronic tag on the hand,

wherein the step of acquiring, by the terminal, the information on the electronic tag on the hand comprises steps of: when
the contactless RF signal coupling of the RFID read-write module and the electronic tag is performed inductively,

converting a change in a distance between an antenna of the RFID read-write module and an antenna of the electronic tag into
a change in an antenna voltage or an antenna current; and acquiring the information on the electronic tag by: modulating,
by a processing module of the terminal, the antenna voltage of the electronic tag and demodulating the antenna voltage of
the RFID read-write module according to resistive load modulated data information transfer.
