The steering wheel input is a flexible, interactive input based on a touch-sensitive surface. Groups of functions are available from many positions of hand surfaces and fingers on said surface. A computer keyboard can be simulated. The keypad of a mobile telephone can also be simulated. PDA inputs can be carried out by means of longitudinally aligned pressure places. Travel directions, headlight flashing/dipping and windscreen wipers can be controlled without having to raise the hand from the steering wheel. Continuous encompassment of the hands is corrected by computer. The interactive surface produces ergonomically appropriate and dynamically updated touch areas, particularly around the middle finger, index finger and thumb. More particularly, differentiation occurs with regard to the activities of curved and extended finger positions. The applications on the steering wheel are highlighted and described with variants. The touch areas are continuously and dynamically adapted in the relationship thereof with respect to the hands or balls of the thumb and fingers. They can also be continuously and dynamically adapted by measuring the real actuated touch places within an experienced time period. Adaptation and training of the input surface areas i.e. the instantaneous touch areas valid for respective signals also occurs by actuation itself. Said interactive surface can: a) react upon touch, b) exhibit fine motor, perceivable, tactile feedback in terms of switch behavior and c) offer fabric layers or coatings with visual feedback. |
