Fast-gesture recognition and classification using Kinect: an application for a virtual reality drumkit

In this paper, we present a system for the detection of fast gestural motion by using a linear predictor of hand movements. We also use the proposed detection scheme for the implementation of a virtual drumkit simulator. A database of drum-hitting motions is gathered and two different sets of features are proposed to discriminate different drum-hitting gestures. The two feature sets are related to observations of different nature: the trajectory of the hand and the pose of the arm. These two sets are used to train classifier models using a variety of machine learning techniques in order to analyse which features and machine learning techniques are more suitable for our classification task. Finally, the system has been validated by means of the Kinect application implemented and the participation of 12 different subjects for the experimental performance evaluation. Results showed a successful discrimination rate higher than 95 % for six different gestures per hand and good user experience.
