A system for promoting physical activity includes at least two cameras which capture images of an object and generate image signals indicative of the captured images. A processor in communication with the cameras receives the image signals from the cameras and determines, based at least on part upon the image signals, when and in what position the object impacts a surface. The processor generates, based at least in part upon the determination of when and in what position the object impacts the surface, feedback signals indicative of feedback to be provided to a user of the system. A projector in communication with the processor receives the feedback signals and, based at least in part upon the feedback signals, displaying visual feedback to the user on the surface.
