STEERING WHEEL INPUT/INTERACTIVE SURFACE
First Claim
1. A computer input device comprising an input face having a plurality of touch-sensitive input face zones and a control unit coupled thereto, characterized in that the device further comprises layers or fabric layers having fibers, wires or in particular lamellas integrated into a touch-sensitive layer or adjacent fabric layers, wherein the fibers, wires or lamellas are configured so that the ratio of the application of force to the spring travel which can be perceived by the fingers behaves nonlinearly and after a certain small spring travel the further application of force does not increase but rather stays the same or decreases again and provides a through connection which can be clearly felt in a sensitive fashion similar to a toggle-lever effect.

Abstract
The steering wheel input is a flexible, interactive input, based on a touch-sensitive surface. Groups of functions are available from many positions of hands and fingers, gripping and controlling the steering wheel. For example travel directions indicators, headlight flashing/dipping and windscreen wipers can be controlled without having to raise the hand from the steering wheel. The keypad of a mobile telephone can also be simulated. PDA inputs can be carried out. A computer keyboard can be simulated Continuous encompassment of the hands is corrected by computer. The touch areas are continuously and dynamically adapted in the relationship thereof with respect to the balls of the hands or the thumb and fingers. This concept produces ergonomically appropriate and dynamically updated touch areas.
