Kinect, a 3D sensing device from Microsoft, invokes the Human Computer Interaction (HCI) research evolution. Kinect has been implemented in many areas, including music. One implementation was in a Virtual Musical Instrument (VMI) system, which uses natural gestures to produce synthetic sounds similar to a real musical instrument. From related work, we found that the use of a large joint, such as hand, arm or leg, is inconvenient and limits the way of playing VMI. Thus this study proposed a fast and reliable finger tracking algorithm suitable for VMI playing. In addition, a virtual guitar system application was developed as an implementation of the proposed algorithm. Experimental results show that the proposed method can be used to play a variety of tunes with an acceptable quality. Furthermore, the proposed application could be used by a beginner who does not have any experience in music or playing a real musical instrument.
