Abstract:
1. A system for promoting physical activity comprising: at least two cameras which capture images of an object as it approaches and impacts a surface and generate image signals indicative of the captured images, at least one of said at least two cameras comprising a side view camera positioned with a viewing axis thereof substantially parallel to the surface, the side view camera capturing images illustrative of when the object impacts the surface, and at least one of said at least two cameras comprising a rear view camera positioned with a viewing axis thereof perpendicular to the surface or at an oblique angle with respect to the surface and such that the viewing axis of the rear view camera points toward the surface, the rear view camera capturing images of the surface itself and illustrative of where on the surface the object impacts; a processor in communication with the cameras, said processor receiving the image signals from the cameras and determining a specific point in time when the object impacts the surface based at least in part upon the images captured by the side view camera and without regard to the images captured by the rear view camera, and in what position the object impacts the surface based at least in part upon the images captured by the rear view camera at the specific point in time and without regard to the images captured by the side view camera, said processor generating, 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 said system; and a projector in communication with said processor, said projector receiving the feedback signals and, based at least in part upon the feedback signals, displaying visual feedback to the user on the surface.
