METHOD AND DEVICE FOR PERFORMING SPATIAL POSITIONING ON ELECTRONIC TAG, 3D SIGNING AND HUMAN-COMPUTER INTERACTION

摘要

Provided are a method and a device for performing spatial positioning on an electronic tag, 3D signature and human-computer interaction. The method for performing spatial positioning on an electronic tag includes: arranging at least three sets of three-dimensionally distributed array antennas on an electronic device, each set of array antennas including multiple antenna array elements extending in one dimension; turning on an electronic tag reader to generate a radio frequency electromagnetic field when spatial positioning is performed on an electronic tag; acquiring induced voltage generated on each antenna array element in each set of array antennas when it is sensed that there is an electronic tag in the radio frequency electromagnetic field; and determining spatial position information of the electronic tag according to the induced voltage. The technical solution of the present invention can use the electronic tag to perform spatial signature, and thereby from a planar handwriting to a spatial handwriting, increases a signature safety factor.
