1. An operating unit, comprising:
a touch-sensitive operating area; and
a control unit, wherein
the touch-sensitive operating area is configured to detect regions of the touch-sensitive operating area touched by a user's finger and configured to transmit information relating to the regions touched by the user's finger to the control unit,
the control unit is configured to determine an activation location on the touch-sensitive operating area from the information relating to the regions touched by the user's finger and, if the determined activation location is in a predefined field of the touch-sensitive operating area, is configured to perform a function assigned to the predefined field,
the control unit is configured to determine the activation location
on or in a region of a boundary line bounding a fingertip and that is at a front in a direction of movement of the user's finger on a surface of the touch-sensitive operating area, only when a determined speed of movement of a course of regions of the touch-sensitive operating area touched exceeds a predefined limit value, and
from an area centroid of all regions of the touch-sensitive operating area touched by the finger at a point in time when the determined speed of movement of the course of regions of the touch-sensitive operating area touched does not exceed the predefined limit value.
