Patent number: 11892562Abstract: A performing device of an impulse-like gesture recognition system executes an impulse-like gesture recognition method. A performing procedure of the impulse-like gesture recognition method includes steps of: receiving a sensing signal from a sensing unit; determining a prediction with at least one impulse-like label according to the sensing frames by a deep learning-based model; and classifying at least one gesture event according to the prediction. The gesture event is classified to determine the motion of the user. Since the at least one impulse-like label is used to label at least one detection score of the deep learning-based model, the detection score is non-decreasing, reaction time of the at least one gesture event for an incoming gesture is fast, rapid consecutive gestures are easily decomposed, and an expensive post-processing is not needed.Type: GrantFiled: October 30, 2020Date of Patent: February 6, 2024Assignee: KaiKuTek Inc.Inventors: Mike Chun-Hung Wang, Chun-Hsuan Kuo, Wen-jyi Hwang, Guan-Sian Wu, Chieh Wu, Wen-Yen Chou, Yu-Feng Wu, Fang Li, Wen-Yen Chang
