Gesture recognition method and system based on RFID (radio frequency identification devices)

Abstract

The invention relates to an information processing technology, and discloses a gesture recognition system based on RFID (radio frequency identification devices). The gesture recognition system comprises an RFID signal information acquisition module used for receiving a wireless signal from a reader by a transponder, and preprocessing an RFID signal; an anomaly detection and extraction module used for using an anomaly detection algorithm to recognize and extract abnormal changes of RFID signal state information; an action recognition module used for recognizing a gesture action by taking an abnormal segment caused by the gesture action as a target action class based on a matching algorithm; and a response recognition module used for executing a meaning that the gesture represents when recognizing a target gesture action. The gesture recognition method and system based on the RFID provided by the invention have the following beneficial effects that the universality is very high, and people subjected to detection do not need to carry any extra equipment, so that the inconvenience caused by carrying detection equipment by people subjected to detection can be avoided.

Description

technical field [0001] The invention relates to information processing technology, in particular to an RFID-based gesture recognition method and system. Background technique [0002] In the current human-computer interaction, gesture recognition is becoming more and more important. Through different body gestures, we can have various interactions with computers or machines. Therefore, gesture recognition is playing an increasingly important role in our lives. For example, in a smart home, we can use gestures to remotely control electrical equipment such as air conditioners and lights. We can use gestures to play somatosensory games and so on. [0003] Existing gesture recognition systems can be divided into the following categories. (1) Vision-based gesture recognition, such as Microsoft's Xbox somatosensory game console, captures human body postures through the camera to play somatosensory games. (2) Based on the wearable Sensor, such as using Myo, the gesture recognit...

Problems solved by technology

[0004] The above methods either need to carry additional sensor equipment, or need to be used in places where the line-of-sight and light are brighter, and the overhead is relatively large, which is not conducive to large-scale deployment.
