A Novel Interference Suppression Method for Gesture Recognition Based on Frequency Hopping

Gesture recognition shows significant applicable values in intelligent connected vehicles (ICVs). However, gesture recognition for in-vehicle interaction faces the challenge of the complex interior environment. To tackle this problem, we present a novel interference suppression method for gesture recognition, which uses frequency hopping (FH) of SparkLink Low Energy (SLE). The experimental results show that the proposed method achieves an overall accuracy of $\mathbf{9 4 \%}$, while the accuracy of the single frequency band method reaches only 89.06%.
