Interactive step-type gymnastics practice device

Abstract

The invention relates to an interactive gymnastics practice device which is used together with an image and sound system forming the gymnastics program to be followed by a user, comprising a first level of generally-pressure-sensitive surfaces, the surfaces extending essentially in a continuous manner and in substantially the same plane. The invention is characterized in that the device comprises at least one second level of surfaces which are pressure sensitive or which can control an action in response to a pressure, the second level surfaces extending essentially in a continuous manner and in substantially the same plane.

1 - 10 . (canceled) 
     
     
         11 . A device for doing interactive gymnastics in association with an image and sound system constituting a gymnastics program to be followed by a user, said device being a protuberant object in the shape of a block, said block comprising:
 one top surface for receiving the feet of a user;   at least two analog weight sensors each able to send to the image and sound system a signal that varies depending on the weight applied by the feet of the user on the top surface for causing an action to take place in response to the signal;   wherein each of said signals transmitted by said at least two weight sensors is accompanied by a specific identifier signal indicative of an identity of the device.   
     
     
         12 . The device of  claim 11 , wherein the block is parallelepiped. 
     
     
         13 . The device of  claim 11 , wherein said device is arranged to recognize the weight of said block. 
     
     
         14 . The device of  claim 13 , wherein said device is self-calibrating. 
     
     
         15 . The device of  claim 11 , wherein said weight sensors are located under said block. 
     
     
         16 . The device of  claim 11 , wherein said block comprises four weight sensors under said block. 
     
     
         17 . The device of  claim 11 , wherein said block comprises four legs located under said block. 
     
     
         18 . The device of  claim 11 , wherein said block comprises a mechanism for increasing or reducing the height of said top surface. 
     
     
         19 . The device of  claim 11 , wherein said at least two weight sensors are pressure-sensitive sensors. 
     
     
         20 . The device of  claim 11 , wherein said block comprises light emitting diodes (LEDs). 
     
     
         21 . The device of  claim 11 , wherein the signals sent to the image and sound system cause a response in a choreography program. 
     
     
         22 . The device of  claim 11 , wherein the signals sent to the image and sound system cause a response in a step program.
