Responsive training device

A responsive rehabilitation device for responding to a user interaction therewith, the responsive rehabilitation device being in the form of a compressible body comprising:

• a surface enclosing the compressible body;
• a controller positioned centrally within the compressible body;
• at least one pressure sensor configured to sense a deformation of the compressible body in response to a pressure applied to the surface and to generate a quantitative sensor output to the controller in response to the pressure applied to the surface;
• at least one transponder positioned inside the compressible body, the at least one transponder configured to provide at least one of an audio output, a visual output or a combination thereof as a function of the quantitative sensor output;
• and
• wherein the controller is configured to control the at least one transponder as a function of the quantitative sensor output,
• wherein the at least one pressure sensor is a capacitive sensor including at least two conducting bodies separated by the controller and a dielectric material, wherein the two conducting bodies are placed substantially parallel to each other on each side of the controller, the capacitive sensor is configured for
• measuring change in capacitance between said at least two conducting bodies, said change in capacitance is a result of a change in distance between the at least two conducting bodies, and
• converting the measured change in capacitance to the quantitative sensor output.
