Sequence-Based Device-Free Gesture Recognition Framework for Multi-Channel Acoustic Signals

ICASSP 2023accepted

Device-free gesture recognition schemes based on acoustic sensing signals are promising solutions for next-generation human-computer interaction systems. However, existing gesture recognition frameworks reuse visual neural networks to perform feature extraction. These approaches ignore the time sequ…
