AI enabled sign language recognition and VR space bidirectional communication using triboelectric smart glove

Nature Communications, Journal Year: 2021, Volume and Issue: 12(1)

Published: Sept. 10, 2021

Sign language recognition, especially the sentence is of great significance for lowering communication barrier between hearing/speech impaired and non-signers. The general glove solutions, which are employed to detect motions our dexterous hands, only achieve recognizing discrete single gestures (i.e., numbers, letters, or words) instead sentences, far from satisfying meet signers' daily communication. Here, we propose an artificial intelligence enabled sign recognition system comprising sensing gloves, deep learning block, virtual reality interface. Non-segmentation segmentation assisted model achieves 50 words 20 sentences. Significantly, approach splits entire signals into word units. Then recognizes all elements reversely reconstructs Furthermore, new/never-seen sentences created by new-order recombination can be recognized with average correct rate 86.67%. Finally, results projected space translated text audio, allowing remote bidirectional signers
