Embodiment Construction

[0039] 1. System scenario

[0040] figure 1 It is a system scene structure diagram, mainly composed of two parts: radio frequency identification module and gesture recognition module. The radio frequency identification module is mainly composed of the following parts: RFID reader, reader antenna, wearable device with RFID tag, and the gesture recognition module is mainly composed of the following parts: intelligent processing terminal, communication device, and interactive terminal. The gesture recognition module interacts with the radio frequency identification module through the communication device. The system (except the reader antenna) can be placed anywhere as required. In order to reduce the influence of the multipath effect in the wireless transmission process and ensure the stability of the signal, the reader antenna is placed about 1m to 1.5m away from the ground. The wearable device with the RFID tag needs to face the antenna directly, between 1m and 2m away from...

Abstract

The invention discloses a remote gesture interaction system based on a radio-frequency identification (RFID) technology and a working method thereof. The system mainly comprises wearable equipment pasted with an RFID tag, an RFID reader, a reader antenna, a smart processing terminal and an interactive terminal, wherein the RFID tag is pasted on the wearable equipment; the reader can acquire signal intensity information and phase information of the RFID tag on the wearable equipment in real time, and transmit the signal intensity information and the phase information to the smart processing terminal through communication equipment; the smart processing terminal is used for performing real-time sensing and identification on gestures of a user based on collected signal intensity information and phase information of the RFID tag, and transmitting the sensed gestures to the interactive terminal through the communication equipment; and the interactive terminal is used for displaying corresponding interaction effects on an application according to different gesture events.

Description

technical field [0001] The invention relates to the technical field of gesture space interaction, in particular to a gesture space interaction system based on radio frequency identification technology and a working method thereof. Background technique [0002] Gesture recognition technology refers to the technology of recognizing human gestures through algorithms such as mathematics and pattern recognition. [0003] With the development of radio frequency identification and wireless communication technology, new application modes based on radio frequency identification (RFID) technology have attracted much attention. With the help of non-contact automatic identification capability and wireless signal transmission technology, the RFID system can obtain the signal strength information of the tag, and with the help of signal analysis and pattern recognition algorithms, it can realize the pattern matching of actions, recognize human gestures, and finally achieve gesture recognit...
