摘要：A computerized musical percussion instrument is disclosed. Markers carried bythe musician are observed by an imager to produce a series of two dimensional imagesover the time of the performance. A processor receives the images and distinguishesbetween markers (e.g. left hand, right hand) by comparing the position and size of

unidentified markers in the current image to the position and size of identified markers inpreceding images. The processor analyses each markers' movements and detects a drumhit when a marker undergoes a sharp reversal of its motion direction after reachingsufficient speed. The processor determines which drum the musician intends to hit bycomparing the position and size of the marker at the instant of the hit to the position andsize attributes of each drum. The processor outputs an audio signal for each hit,corresponding to the drum hit, with a volume determined by marker speed.
