Method and apparatus for 3D signature and human computer interaction for spatial positioning of electronic tags

摘要

A method and apparatus for 3D signature and human computer interaction for performing spatial positioning on an electronic tag, wherein the method for performing spatial positioning on the electronic tag includes at least three groups distributed in three dimensions in the electronic apparatus. An array antenna is installed, and each group of array antennas includes a plurality of antenna array elements extending in one dimension, and when performing spatial positioning on the electronic tag, the electronic tag reader is activated and the radio frequency is When generating an electromagnetic field and sensing that an electronic tag exists in the radio frequency electromagnetic field, collecting the sensitive voltage generated in each antenna array element in each group of array antennas, and based on the sensitive voltage, Determining spatial position information of the electronic tag. The technical solution of the present invention can perform a spatial signature using an electronic tag, and improves the safety factor of the signature by converting the plane handwriting into the space handwriting.
