The invention relates to an operating unit (1) having a touch-sensitive operating surface (3) and a control unit (5), the operating surface (3) being designed to detect a touch area and to transmit information relating to the touch area to the control unit (5), the control unit (5) determining an activation point on the operating surface (3) from the information relating to the touch area, when the activation point is located in a predetermined block, a function associated with the block is executed, and only when the determined movement speed of the course of the touch area of the operating surface (3) exceeds a predetermined limit value, the function is executed. The control unit (5) determines the activation point from a position on or in the region of a boundary line which delimits the fingertip and is located in front of the direction of movement of the finger on the surface of the operating surface (3), and otherwise determines the activation point from the surface center of gravity of all regions of the operating surface (3) which are touched by the finger at a point in time.
本发明涉及一种操作单元(1),它具有触敏操作面(3)和控制单元(5),其中,该操作面(3)设计用于检测触摸区域并且传输关于触摸区域的信息至控制单元(5),其中,该控制单元(5)从关于触摸区域的信息中确定操作面(3)上的激活位点,并且当该激活位点位于预定的区块中时执行配属于该区块的功能,其中,仅当操作面(3)的触摸区域的走向的所确定的运动速度超过预定的极限值时,控制单元(5)才从限界指尖的、沿操作面(3)的表面上的手指的运动方向靠前的边界线上或边界线区域内的位置确定该激活位点,否则从操作面(3)的在一个时刻由手指触摸的所有区域的面重心确定该激活位点。
