VPI Player: An Approach for Virtual Percussion Instrument using Kinect

Today the HCI application become more popular due to increasing use of gesture recognition which easily removes mechanical devices for operating system and helpful for human being to operate system naturally. A VPI player is way to check the skills of all level of instrument player including professional, non-professional, new learner. VPI player captures the hand movements of person and by using information of captured gesture it produce sound of selected instrument. In this paper, the proposed system is real time music system emphasis on percussion instrument only which introduces kinect as image acquisition device which eliminates lighting condition, cluttered background. Use of cosine algorithm to calculate difference between the hands coordinates and instrument coordinates. VPI player is most promising way to produce sound through hand gesture with increased accuracy and efficiency.
