Ultrahigh-frequency passive touch sensing RFID tag for man-machine interaction and use method thereof

Abstract

The invention discloses an ultrahigh-frequency passive touch sensing RFID tag for man-machine interaction and a use method thereof, the tag comprises an antenna main body, a coupling feed ring and a short-circuit metal sheet, and the coupling feed ring comprises a ring structure, a short-circuit connection sheet and an RFID chip; the tag in the invention can also be used as a structural unit, anda plurality of units can be orderly arranged to form wireless man-machine interaction equipment. The label is simple in structure, low in cost and convenient to process; the device is completely passive and long in service life; ultra-thin flexible folding is achieved, and carrying is convenient; the adhesive tape can be attached to various objects, even the surfaces of human bodies and clothes, and is convenient to use; the effective working distance is long and can reach up to more than ten meters without being limited by the sight distance; the same receiver can read input information of aplurality of devices at the same time. In conclusion, the designed RFID tag can achieve touch sensing and has the advantages of being simple in structure, portable, low in cost, convenient to use, long in working time, long in working distance, high in adaptability and the like.

Description

technical field [0001] The invention belongs to the field of antenna technology and wireless communication, and relates to an ultra-high frequency passive touch sensor RFID tag for human-computer interaction and a usage method. Background technique [0002] Human-computer interaction technology (Human-Computer Interaction Techniques) refers to the technology that realizes the dialogue between human and computer in an effective way through computer input and output devices. In recent years, with the trend of miniaturization and portability of electronic equipment such as computers, requirements for miniaturization, light weight, and longer use time have been put forward for human-computer interaction equipment. Although new human-computer interaction technologies such as augmented reality (AR), virtual reality (VR), speech recognition, and gesture recognition are currently developing rapidly, they rely on image and speech recognition algorithms that are still in the developme...

AI Technical Summary

Problems solved by technology

[0004] 2. Use time: traditional wireless human-computer interaction devices are generally powered by batteries, and the use time is limited by the power;

[0005] 3. Adaptability: Traditional wireless human-computer interaction devices generally have a one-to-one correspondence between receivers and supporting equipment. When configuring multiple different wireless human-computer interaction devices on the same computer, multiple different receivers must be installed, which greatly occupies computer interface space
