Today’s invention is a new intuitive driving interface -something like a mouse moving on a mousemat.
A car driver grips a model car and moves it across the surface of a model rolling road inside the fullsize car. As the model car is turned, so the axial direction of the rolling road turns relative to the real car.
As the speed of the model is varied so the rolling road accelerates and the speed of the real vehicle responds.
A crude version of this could be achieved using eg an iPhone or Wii attached to the base of a model vehicle. It would be particularly good for people with a problem reversing or for those with physical disabilities (since there are no pedals etc required).
