Untersuchungen und Gestaltungshinweise für adaptive multifunktionale Stellteile mit aktiver haptischer Rückmeldung

The number of operable functions of a product is associated with the number of operating elements and displays. If there are too many elements and displays, the user friendliness is affected because of the increased complexity of this kind of human machine interface. To reduce this complexity, the substitution of many single operating elements by one adaptive multifunctional operating element is a possible solution of this problem. An adaptive multifunctional operating element is defined as an element for the operation of several functions. Because of its active components and the haptical feedback resulting from these components, an adaptive multifunctional operating element can be adapted to the situation, the user or the task. Therefore, with such an operating element, it is not only possible to haptically transmit information, which, up to now, are displayed visually but also to reduce operating errors .
