A gesture recognition system comprises: a signal collection terminal, configured to collect and preprocess gesture data of a gesture object; a local recognition device, configured to extract features from the gesture data received from the signal collection terminal, form a multi-dimensional feature vector based on extracted features, establish local gesture models based on the multi-dimensional feature vector and perform local gesture recognition according to the local gesture models; and a cloud server, configured to receive the multi-dimensional feature vector from the local recognition device when there is a network connection between the local recognition device and the cloud server, establish cloud gesture models based on the received multi-dimensional feature vector and perform cloud gesture recognition according to the cloud gesture models. A gesture recognition method is also disclosed.

Gesture recognition system and gesture recognition method

A virtual inputting device comprises: a signal collection unit including a bioelectrical sensor for collecting bioelectrical signals and an acceleration sensor for collecting acceleration signals; a signal preprocessing unit for performing preprocessing for the bioelectrical signals and the acceleration signals collected by the signal collection unit; a signal segmentation unit for performing segmentation processing for the preprocessed bioelectrical signals and acceleration signals so as to obtain a plurality of gesture segments; a feature extracting unit for extracting feature values from the bioelectrical signals and the acceleration signals for respective gesture segments; a feature combination unit for combining feature values extracted from the feature extracting unit to form a combined feature vector; a gesture recognition unit for performing gesture recognition based on the combined feature vector; and a character mapping unit for obtaining characters corresponding to the recognized gesture according to a predetermined mapping relationship between characters and gestures.
