  • Patent number: 4995607
    Abstract: An interactive sports training device comprises a screen mountable adjacent a playing area. An array of sensors is mounted on the back of the screen for generating an electrical sensor signal in response to the impact of an object against the screen, the sensor signal being representative of the location, and preferably force, of the impact. A programmed central processing unit receives the sensor signal and generates a response signal. A display receives the response signal and displays a preselected message dependent on the response signal received. The message generates is thus dependent on the location, and preferably force, of the impact.
