This study proposes the development of a virtual environment, as a computer game format, that aid the training and the practice of Paralympic sport shooting, using a digital image analysis system, involving techniques of acquisition and processing of acquired images. The image acquisition was performed by a webcam that interacts with the software, which performs the processing and image analysis in matrix form, displaying the results dynamically inside the game's screen. It can be said as a conclusion that it was possible to use programming techniques in Mat lab, combined with the capture and image processing, to create a training tool able to simulate the practice of Paralympic sport shooting, providing the appropriate interactivity using graphic interfaces.
